I created this topic because it is the #1 reason for global carbon emissions. Here is a 2015 Time Magazine climate change list to back that up: http://time.com/3935248/am-i-hurting-the-planet/

In the August 2015 Consumer Reports magazine, check out the list on page 63, of oil-gulping vehicles, which alone is worth the price for that magazine issue. The biggest surprises on that list for me are the following, with % of vehicles needing at least 1 qt. oil between oil changes in parentheses. Newest model years fare best, and 2010 model years (shown below) fare worst:

Subaru Outback (14), Subaru Legacy (19), Subaru Forester (4), Subaru Impreza (2), Volvo XC60 (6), Volvo XC70 (13).

Bottom line: Save your motor oil purchase receipts to show your car dealer in order to get repairs. If you buy any of the vehicles on that list, also purchase an extended warranty.

"Britain to ban sale of all diesel and petrol cars and vans from 2040

"As part of a government strategy to improve air quality, Britain is to ban all new petrol and diesel cars and vans from 2040 amid fears that rising levels of nitrogen oxide pose a major risk to public health.

"The commitment, which follows a similar pledge in France, is part of the government’s much-anticipated clean air plan, which has been at the heart of a protracted high court legal battle."

8 contd. Solar sails sound a little tricky--wonder what design they went with in the end.

Solar, wind powered ferries to sail on S.F. Bay
‘Like switching from a gas guzzling SUV to a hybrid car,’ activist says
Miguel Llanos | 5/25/2006

Two (600-passenger) tourist ferries powered in part by the wind and the sun will carry visitors to San Francisco’s Alcatraz island under a contract between the National Park Service and a private company...

...Solar Sailor, an Australian company...operates a similar ferry in Sydney.

...one Solar Sailor concept includes a large, rigid wing covered in solar panels that captures solar and wind power while also allowing sail navigation when conditions are right. In bad weather, the sail folds down flat above the deck like a roof.

...“Large batteries on board the vessels will store electricity generated by the diesel generators and collected by solar panels,” Bluewater said in a statement. “The electricity then powers the electric motors.”

The batteries allow the diesel engines to be turned off at port, which means no smells or emissions at the boarding ramp. The vessels can also be plugged into an onshore power outlet to recharge the batteries.

The diesel generators themselves will burn low-sulfur fuel and will have pollution controls that cut emissions by 70 to 90 percent compared to conventional marine diesels...

World's first electrified public road opens in Sweden
Apr13 2018

...The 2km stretch outside Sweden's Arlanda Airport ...

An electric truck working for the logistics company PostNord will over the next 12 months use the road to stay charged as it shuttles deliveries between Arlanda Airport and its distribution centre 12km away.

The truck has been fitted with a connector underneath its chassis which attaches to an electrified groove in the road, drawing power like a car on a Scaletrix track.

"Everything is 100 percent automatic, based on the connector magnetically sensing the road," Hans Säll, Chief Executive of the eRoadArlanda Consortium, told The Local. "As a driver you drive as usual, the connector goes down onto the track automatically and if you leave the track, it goes up automatically."

..."You can send data through electric cables, so it's no problem to identify the car, and the rail will know if you are allowed to draw electricity or not and it will be able to charge you."

... there's an enormous difference in cost between having cars with big batteries, and cars with small batteries and electric roads."

But he said that setting up a national system would require investment in infrastructure.

...overhead cables developed by the German engineering giant Siemens..."can only handle heavy traffic"

.safety risk is minimal.

"The electricity is about 6cm down in the tracks and the electricity is also connected to the earth, so even if we flood the road with salt water, if you measure the electricity at the surface, it's less than one volt."

Collectively, the world's ships emit the same amount of carbon as Germany, and air quality is a local issue in ports. Fascinating to me, at least, the strategies that can help bring down fuel use (BBC audio report below).

The UN's International Maritime Organization has decreed that as of Jan 1, 2020, allowable sulfur content of fuels will decrease from 3.55% (heavy fuel oil, $450-500 per ton(ne?)) to 0.5% (marine distillate, 30-60% more expensive), which will drive fuel efficiency strategies. An existing cargo ship with life span of ~40 years will have fewer options to reduce fuel use than newly constructed ones. (I bet there will be pressure to change Jones Act, which stipulates that ships that serve US ports only must be built in the US.)

Record private jet flights into Davos as leaders arrive for climate talk
Rebecca Ratcliffe | Tue 22 Jan 2019

David Attenborough might have urged world leaders at Davos to take urgent action on climate change, but it appears no one was listening. As he spoke, experts predicted up to 1,500 individual private jets will fly to and from airfields serving the Swiss ski resort this week.

Political and business leaders and lobbyists are opting for bigger, more expensive aircrafts, according to analysis by the Air Charter Service, which found the number of private jet flights grew by 11% last year.

“There appears to be a trend towards larger aircraft, with expensive heavy jets the aircraft of choice, with Gulfstream GVs and Global Expresses both being used more than 100 times each last year,” said Andy Christie, private jets director at the ACS.

This is partly due to the long distances travelled, he said, “but also possibly due to business rivals not wanting to be seen to be outdone by one another”. Last year, more than 1,300 aircraft flights were recorded at the conference, the highest number since ACS began recording private jet activity in 2013.

Countries with the highest number of arrivals and departures out of the local airports over the past five years included Germany, France, UK, US, Russia and the United Arab Emirates, according to ACS.

The World Economic Forum’s global risk report, released ahead of this week’s meeting, identified environmental challenges, including the failure to mitigate climate change, as top of the list of dangers facing the world economy...

Air quality on cruise ship deck 'worse than world's most polluted cities', investigation finds
Chloe Farand | 4 July 2017

...Daniel Rieger, of the German environment association NABU (Nature And Biodiversity Conservation Union), said: “Ships cause not only greenhouse gas emissions, but also sulphur oxides, nitrogen oxides and particulate matter.

"Per day one cruise ship emits as much particulate matter as a million cars. So 30 cruise ships pollute as much as all the cars in the United Kingdom.”

...John Maggs, president of the Clean Shipping Coalition, also told Dispatches: “Most large ships burn heavy fuel oil. It’s a residual product from the refining industry, so after the refiners have produced the petrol and diesel we put in our cars, they’re left with what is essentially a waste product. It’s called residual fuel, or heavy fuel oil.

"From an environmental point of view, it’s bad because of the air pollution caused by the very high sulphur content. The shipping industry, however, has traditionally liked it because it’s much cheaper than other fuels.”...

Swedish shipping to go fossil-free by 2045
Sami Grover | February 14, 2019

This could speed up progress for the industry in general.

From spinning sails to kite-power, there are plenty of ideas out there for reducing the carbon footprint of the shipping industry. Usually, however, they are supplemental power sources, designed to reduce overall emissions, but not eliminate them entirely.

Business Green reports, however, that the Swedish shipping industry has loftier goals: aiming to go 100% fossil fuel-free by 2045. Specifically, the Swedish Shipowners' Association is working with a government initiative called Fossil-Free Sweden to figure out a roadmap for their industry to contribute to overall national goals of 70% emissions cuts for domestic transport by 2030, and net zero by 2045.
If achieved, that would put Sweden ahead of shipping giant Maersk—which is aiming for the same goal by 2050. But it's good to see pressure building from multiple sides, hopefully creating the kind of competition that can move innovation forward even faster than expected. (It's worth noting that this comes hot on the heels of concern that installing scrubbers on existing ships and/or switching to lower sulphur fuels could be counterproductive.)

Now, exactly how the industry achieves its lofty goals remains to be seen, but an opinion piece by two industry leaders suggests they are betting on a mix of electric propulsion, significant efficiency improvements and 'low carbon' biofuels (careful now!) to get them where they need to go...

SeaBubbles shows off its ‘flying’ all-electric boat in Miami
Sarah Perez / 2/17/2019

...This innovative boat design combines technology from nautical industries and aviation and intelligent software to raise the hull of the boat out of the water using foils, which helps it consume less energy by allowing it to travel on rougher waters with reduced drag, while also keeping the passenger cabin relatively comfortable.

When raised, the boat is “flying” above the water, so to speak.

...a way for cities to reduce traffic congestion and help the environment by taking advantage of the area’s waterways to move people around in fast water taxis.

...a normal boat with a normal combustion engine, the fuel price you’re paying is between $70 and $130 per hour. With us, it’s $2,” he says.

The cost savings come from an all-electric design, which means the boat charges at a power station — preferably one that’s solar charged, of course — instead of guzzling gas...

If Seeing the World Helps Ruin It, Should We Stay Home?
Andy Newman | June 3, 2019

In the age of global warming, traveling — by plane, boat or car — is a fraught choice. And yet the world beckons.

The glaciers are melting, the coral reefs are dying, Miami Beach is slowly going under.

Quick, says a voice in your head, go see them before they disappear! You are evil, says another voice. For you are hastening their destruction.

To a lot of people who like to travel, these are morally bewildering times. Something that seemed like pure escape and adventure has become double-edged, harmful, the epitome of selfish consumption. Going someplace far away, we now know, is the biggest single action a private citizen can take to worsen climate change. One seat on a flight from New York to Los Angeles effectively adds months worth of human-generated carbon emissions to the atmosphere.

And yet we fly more and more...

Scientists reduce friction--at atomic levels at least:

Scientists seek materials that defy friction at the atomic level
Going super-slippery could help cut down on energy loss
Emily Conover | August 1, 2019By

...by scrutinizing atoms’ wily ways, scientists are devising new techniques to cut down on friction, going beyond known slippery surfaces like ice, Teflon and the banana peel of countless comedy gags. Some scientists have found ways to bring friction down to near-zero levels, a property known as superlubricity. Others are studying quantum effects that reduce friction.

...Atomic acrobatics might help turn friction up and down at will, a useful ability since there are times when friction, a force working against the motion of a sliding or rolling object, is helpful. The frictional force of tires on asphalt, for example, lets a car turn without spinning out. But friction also saps the car’s speed, so that more energy is needed to keep the vehicle moving.

...Some materials slide easily over one another, while others require extra oomph to move. That movability is described by a number called the coefficient of friction. The more slippery the pair, the lower the coefficient. The numbers below are estimates; exact values depend on conditions.

Sliding materials Coefficient of friction
Index finger on sandpaper 1
Tires on dry pavement 1
Tires on wet pavement 0.6
Steel on steel 0.6
Tires on icy pavement 0.2
Banana peel on linoleum 0.07
Steel on Teflon 0.04
Steel on ice 0.01

...Gaining the ability to wrangle friction could have real-world consequences. It’s estimated that a third of the energy that goes into powering fossil fuel–guzzling cars is lost to friction, converted into other forms of energy like heat and sound. The same hindrance affects just about every other machine imaginable, so that an estimated one-fifth of the world’s annual energy consumption goes to fighting friction. Reducing those losses would mean “huge savings”...

UK rail line becomes first in world to be powered by solar farm (Guardian)

The world’s first solar farm to power a railway line directly is due to plug into the track near Aldershot, paving the way for solar-powered trains.

From Friday, about 100 solar panels at the trackside site will supply renewable electricity to power the signalling and lights on Network Rail’s Wessex route.

The 30kW pilot scheme could pave the way for a larger project capable of directly powering the trains that use this route from next year.

The solar breakthrough comes as Network Rail plans to spend billions of pounds electrifying rail lines to avoid running trains on diesel. This could help reduce air pollution, greenhouse gas emissions and costs.

Solar panels are already used to power the operations of train stations, including Blackfriars in central London. But the Aldershot project is the first time a solar array will bypass the electricity grid to plug directly into a railway’s “traction” system...

Yes, trolley buses were widespread in London in my youth, and as you say they still exist in Toronto and probaby one or two other places. Wiring routes in a city where all the trolley buses on a particular route belong to the same company, though, is on a rather different scale than wiring long distance motorways. But who knows, it might happen.

Until shore charging infrastructure is in place, west coast ferries will continue to burn fuel, sounds like.

Also, unless just too decrepit, fuel-burning ferries will no doubt be sold to other uses. The fuel-burning Wolfe Islander III will serve as backup during busy summers and in emergencies--it has 15-20 years left in its lifespan I think?

Growing demand for SUVs 'could negate electric car benefits' (Guardian)

The world’s thirst for oil will continue to grow over the next two decades, with climate-damaging emissions climbing until at least 2040, the global energy watchdog has warned, pointing the finger at the growing appetite for gas-guzzling cars.

Growing demand for SUVs in the US, China, Europe and elsewhere could negate all the environmental benefits of the increased use of electric cars, the International Energy Agency (IEA) says. Because of their size, SUVs are harder to electrify than smaller vehicles...


I have to confess I drive a large 4WD diesel, but I hesitate to call my 20-year old Land Rover an "SUV". Mine isn't a Chelsea Tractor (a UK soubriquet for the large SUVs which are used only to pick up the kids from posh private schools in an exclusive part of London where the chance of going off-road is roughly similar to that of a snowball in hell), it's a working vehicle which we need as we have to negotiate a rough and frequently muddy 25 km dirt road to get to the nearest tarmac road. There are now electrification kits available for Landies, used on some tourist safari vehicles, but at the moment the cost looks to be in the region of USD 30,000, the range is only about 60 km or so between recharges, and since I am off grid I would have to invest in a lot more solar panels and batteries in order to be able to charge it. Not an option at the moment. Maybe prices will come down and technology will improve.

A Major but Little-Known Supporter of Climate Denial: Freight Railroads (The Atlantic)

In the fight against climate change, the nation’s freight railroads have painted themselves as heroes. Rail is the “the most environmentally friendly way” to move cargo over land, says the Association of American Railroads, the industry’s trade group. The industry’s four biggest companies agree: “Railroads are essential to moving {climate} objectives forward,” says CSX Transportation, the largest railroad east of the Mississippi.

Yet for almost 30 years, the biggest players in the freight-rail industry have waged a campaign to discredit climate science and oppose almost any federal climate policy, reveals new research analyzed by The Atlantic.

The four largest American freight railroads—BNSF Railway, Norfolk Southern, Union Pacific, and CSX—have sat at the center of the climate-denial movement nearly since it began, documents and studies show. These four companies have joined or funded groups that attacked individual scientists, cast doubt on scientific consensus, and rejected reports from major scientific institutions, including the United Nations–led Intergovernmental Panel on Climate Change. Their effort has cost at least tens of millions of dollars and outlasted individual leaders and coalitions...

Why you shouldn't feel too guilty about flying (Business Insider)

But I also think the debate around flying -- particularly the Swedish notion of flygskam, or flight shame -- reflects a larger problem in the way we talk about climate change.

It's a conversation that is heavily skewed toward individual behavior and personal choice -- how much I fly, what kind of car you drive, whether we've installed efficient light bulbs. And that obscures a much bigger, and more important, picture.

While we fret over our own actions -- and each other's -- we are failing to ponder much more consequential questions about how the systems that shape our lives have led us to this point of crisis. Questions about corporate malfeasance, the power of big money and decades of political failure.

The finding that just 100 companies -- including vast oil and gas concerns -- are responsible for 71% of all greenhouse gas emissions since 1988 has provided a framework for a different way of thinking about this problem.

This approach, rather than blaming individuals for living in the world as it is, places responsibility on big fossil fuel companies that have known for decades what their products were doing to the climate but chose to propagate doubt about the overwhelming scientific evidence instead of working to develop cleaner alternatives.

It also places it on the politicians who have too often done their bidding, failing to use their power to demand reductions in carbon emissions.

"The big polluters' masterstroke was to blame the climate crisis on you and me"...


Interesting argument (by "an environmental journalist, and I care tremendously about the climate"). While it doesn't remove the need for individuals to take their own responsibility for climate change, it's an interesting thought that the big corporations have done a first class PR job of shifting all the focus to individual actions while themselves continuing to produce 71% of the greenhouse gas emissions.

Airless tires

Bridgestone Airless Tires Are Coming to a Semi-Truck Near You—But First, Bikes

The company's airless tires are composed of three pieces—the wheel, the "web," and the tread.

The company has developed an airless truck tire rated to support 5,000 pounds at speeds of up to 75 mph without overheating. (A comparable pneumatic tire would need to be inflated to 120 psi for the same duty cycle.) Apparently, the time saved by fleet managers no longer needing to check and maintain tire pressures—as well as spent repairing punctures and blowouts on the road—is significant.

Kimpel also told us that this is a sustainability play for Bridgestone, given that unlike pneumatic tires, the rubber tread can be replaced as it wears without worrying about whether it's airtight. They don't know yet about the service life of the wheel and web, though they say they're looking into how the components can be reused to maximize sustainability. Bridgestone has been eyeing airless tires for years, and it isn't the only tire manufacturer looking at the tech—Michelin has been toying with the idea, too.

Is this the start of an aviation revolution? (BBC)

As air journeys go, it was just a short hop into the early morning sky before the de Havilland seaplane splashed back down on the Fraser River in Richmond, British Columbia. Four minutes earlier it had taken off from the same patch of water. But despite its brief duration, the flight may have marked the start of an aviation revolution.

Those keen of hearing at the riverside on that cold December morning might have been able to pick up something different amid the rumble of the propellers and whoosh of water as the six-passenger de Havilland DHC-2 Beaver took off and landed.

Climate change means longer take-offs and fewer passengers per aeroplane – new study (The Conversation)

As the local climates at airports around the world have changed in the past few decades, the conditions that pilots have relied on in order to take off safely have changed too. Our new research suggests that higher temperatures and weaker winds are making take-off more difficult. In the long run, this means that airlines are delivering fewer passengers and cargo for the same amount of fuel...

climate change isn’t just about temperature – winds are slowing down and changing direction around the world too. This is a problem for airport runways that were built many years ago to align with the prevailing winds at the time.

Research has predicted that take-off distances will get longer as the climate warms. This is because higher temperatures reduce air density, which the wings and engines need to get airborne. With reduced headwinds, aeroplanes also need to generate more groundspeed just to get into the air. Once they’re up there, they’re subject to in-flight turbulence, which is getting worse due to climate change increasing the energy in jet stream winds...


It's close on 25 years since I was involved in running humanitarian airlifts in Sudan, but I seem to recall that a C-130 taking off in the relative cool of dawn could carry 19 tons of food aid to drop on people's heads, while the same aircraft taking off in the heat of the afternoon (with the temperature often in the forties C) could only carry 12 tons.

Of personal interest to me as we often travel in Cessna Caravans in South Sudan - it's a very popular aircraft for humanitarian aid operations. A range of 100 miles would be useless here, though, as few journeys are as short as that. Hopefully the range will gradually be increased.

for shorter journeys with multiple travel options, some academics argue that a cultural change is necessary.

A solution could be integrated ticketing across all modes of transport, ensuring connections are automatically rebooked, whether by land or sky. This idea is already taking off. Some airlines, including AirFrance, offer passengers combined air and rail tickets. Lufthansa is working with Deutsche Bahn to replace flights with trains for national connections. Renfe, the national rail provider in Spain, is also working towards an integrated service which could include short air segments alongside longer train journeys.

green hydrogen ("water split by electrolysis using renewables such as wind or solar, producing hydrogen and oxygen")
blue hydrogen ("natural gas split into hydrogen and CO2, with the CO2 captured and stored)

gray hydrogen ("as blue hydrogen, but the CO2 is not captured but released into the atmosphere")

American trains need more than railfan nostalgia
A review of "Amtrak, America's Railroad"
Eric Goldwyn and Jonathan English | Nov 6, 2021

Amtrak, America’s Railroad: Transportation’s Orphan and Its Struggle for Survival from Geoffrey H. Doughty, Jeffrey T. Darbee, and Eugene E. Harmon

...When (Amtrak) was formed 50 years ago as a publicly-owned private corporation to take over the money-losing passenger operations from 20 private railroad companies, many expected that within a few years intercity rail travel would be replaced entirely by “modern” bus and air travel.

The United States Government provided Amtrak with $40 million while the private railroads contributed a more significant sum, roughly $200 million to ensure a smooth transition from passenger rail to intercity bus and air travel. But most of the cash flowed back to the private railroads for use of their trains, crews, and tracks. Today Amtrak remains in a liminal state. It has neither faded away, as many expected, nor become a modern passenger railroad that contributes meaningfully to transportation, decarbonization, or economic development goals outside of the Northeast Corridor.

...Outlined clearly in the book, Amtrak’s greatest problems stem from transportation policies that disadvantage passenger rail, uncertainty stemming from two-year allocations from Congress, and a governance structure that has inevitably pit the Amtrak board against the revolving door of Amtrak presidents...

...Unexamined in the book, however, is the connection between railroads, land use, and alleged economic development goals.
If towns and cities want to retain Amtrak service that operates at a loss, they need to cultivate a land-use mix that attempts to support rail travel by making the stations an anchor of development that can serve as a destination for, or source of, riders...

...High-speed rail, which doesn’t exist in the United States, is most competitive with automobiles and airplanes on short- to medium-length journeys that are less than 5 hours, or about 500 miles. Slower conventional rail is competitive only on even shorter distances. This is unfortunately the challenge for most Amtrak services outside the Northeast Corridor. In many cases, they struggle even to compete on travel time with the automobile...

Rwanda goes electric with locally made motorbikes (BBC)

The start-up Ampersand is pioneering the switch and hopes that over the next five years almost all of Rwanda's motorbikes will be electric. It is an ambitious dream - there are around 25,000 motorbike taxis operating in Kigali, some driving up to 10 hours a day, often covering hundreds of kilometres daily. "Motorbikes make up more than half of all vehicles in this part of the world"... "In Rwanda, drivers spend more in a year on petrol than the cost of a new motorbike. We've shown that we can offer an alternative in the same style as their current motorbike {that} costs less to buy, less to power and less to maintain"... savings on fuel and maintenance can double a driver's income...

It's Time To Be Clear: Rail And Public Transport Are The Quickest Way To Reach Decarbonisation (Rail Africa)

If we really want to make transport faster, cheaper and easier for all, let’s first provide people with more and better rail and public transport...


Can we use big batteries to power our trains? (Ars Technica)

With the rapid pace of development in electric vehicles, we will likely get to a place where eliminating carbon emissions from one form of transport is possible. But cleaning up the remaining major modes—planes, trains, and ships—appears to be considerably more challenging. A new analysis suggests we have a good idea of how to improve one of those.

The study, performed by California-based researchers, looks at the possibility of electrifying rail-based freight. It finds that the technology is pretty much ready, and under the right circumstances, the economics are on the verge of working out. Plus, putting giant batteries on freight cars has the potential to create some interesting side benefits...

Hunt for the ‘Blood Diamond of Batteries’ Impedes Green Energy Push
Dionne Searcey and Eric Lipton | Nov. 29, 2021

Dangerous mining conditions plague Congo, home to the world’s largest supply of cobalt, a key ingredient in electric cars. A leadership battle threatens reforms.

...Batteries containing cobalt reduce overheating in electric cars and extend their range, but the metal has become known as “the blood diamond of batteries” because of its high price and the perilous conditions in Congo, the largest producer of cobalt in the world. As a result, carmakers concerned about consumer blowback are rapidly moving to find alternatives to the element in electric vehicles, and they are increasingly looking to other nations with smaller reserves as possible suppliers.

There is a chance that Congo’s role in the emerging economy could be diminished if it fails to confront human-rights issues in its mines...

IF Rider Express has re-started Calgary to Regina, I could go again, but they only got that running (briefly) as covid hit (then it was cancelled again for obvious reasons).

4 Nairobi Bus Operators Now Using Electric Buses (Clean Technica)

one of Nairobi’s top public transportation providers, Embassava Sacco, has announced the introduction of four electric buses to its fleet... Embassava Sacco took delivery of 4 BYD K6 electric buses. The BYD K6 has a range of about 250 km. Embassava Sacco has become the 4th Nairobi bus operator to adopt electric buses, which is a significant milestone. BasiGo began supplying electric buses to bus operators last year after a successful 6-month pilot program. The fact that 4 bus operators have already adopted electric buses in such a short time is an outstanding achievement. It shows that confidence in the new technology is growing in the local sector...

Debunking three big myths about bike lanes
Taylor C. Noakes | May 24, 2023

Bike lanes do not increase congestion
a single two-way protected bike lane can move about 10 times as many people, and do so using less space, than a single lane of car traffic.
Protected bike lanes don’t just help decongest — they help decarbonize and improve public health and fitness.

Bike lanes are good for business
Over the course of a month, a cyclist or pedestrian will spend 40 per cent more than a motorist. Improvements to the public realm that facilitate pedestrian or cyclist access can increase retail sales by as much as 30 per cent. Installing bike-parking infrastructure can yield as much as five times the amount of retail spending per square metre than the same allowed to car parking. Cyclists and pedestrians were also shown to visit the small businesses of their local commercial thoroughfares more frequently than motorists did — frequently twice as often.

Bike lanes improve safety and reduce collisions
latest studies that demonstrate, unequivocally, that adding protected bike lanes improves safety not only for cyclists, but also for all road users.

Snapshots of the End of Travel: On Trying to Enter a Personal No-Fly Zone
Amy Benson Wrestles With the Devastating Consequences of Air Travel
Amy Benson | June 14, 2023

...travel is not neutral, ethically or ecologically. You drop into a different culture, a woven mat of flora and fauna, but you bring you with you. Never neutral...

Large aircraft burn about one gallon of jet fuel per second. Climate scientists have learned to use literary devices—imagery and analogy—to help us understand the numbers. The Suzuki Foundation, a science-based environmental nonprofit, takes a few tacks. The micro: one five-hour flight emits as much carbon “as heating a European home for an entire year.” And the macro: “If the aviation sector were a nation, it would be among the top ten global emitters.” The BBC puts it this way: a one-way “flight from London to San Francisco emits… more than twice (the CO2) produced by a family car in a year.”

...flying is almost always worse {than driving}...

Jet fuel produces an average of 21.5 pounds of CO2 per gallon and aviation gas 18.4, while auto fuel produces 19.6. Not a calamitous disparity, but airplanes burn a tremendous amount of fuel taking off and landing. And then there are the contrails, a mixture of CO2, heavy soot, and water vapor. Contrails “that persist for hours can form human-made cirrus clouds, which trap huge amounts of thermal radiation that would otherwise escape into space.” The radiation trapped by these clouds causes “a warming impact 3x that of CO2.” ...

Not computed in the carbon footprints of flights is the jet fuel airlines sometimes dump in the atmosphere when they need to lighten the plane before landing. They try to avoid this by filling the tanks with little over the fuel needed for the voyage. British Airways once estimated that “only .01% of fuel used by the aviation industry each year is dumped.” But that still equals “almost two million gallons (per year) by U.S. airlines alone.”

Jet fuel emissions are set to spiral upward, just as the planet approaches the climatological Tipping Point. Currently, flights make up 2.5-5% of global emissions, though many climate scientists would weight the percentage higher to reflect the outsize damage those emissions cause. And this is with just three percent of the world population flying—the wealthiest citizens of the wealthiest countries. With burgeoning middle classes in China and India, the most populous nations, the number of passengers is “set to double in the next 20 years.” Even factoring in expected innovations in efficiency, emissions are expected to triple by 2050.

Oh, but carbon offsets! Modern day Indulgences, built on similarly shaky theology. It takes a leap of faith, in fact, to believe in the power of offsets to buy a clean conscience and a smaller footprint. The main mechanism for offsets is planting trees, but those trees are usually monoculture “forests,” terrible as a platform for biodiversity, and extra vulnerable to pests, fires, and species extinction. ...

"It is difficult to separate seeing and taking: the privilege of being among the 3 percent of the world’s population that flies."

Often, not a tree is planted. The money is paid, instead, to landowners (usually already wealthy) to prevent potential deforestation. But can hypothetical tree-saving cancel out the burning of an actual tank of jet fuel? What offsets do accomplish is market protection, ensuring guilt-free flights, cruises, tours, and resorts. Kevin Anderson, climate researcher for Nature, definitively scorches the offset economy as “…worse than doing nothing. It is without scientific legitimacy, is dangerously misleading and almost certainly contributes to a net increase in the absolute rate of global emissions growth.”...

Runs from Quebec City to Baie-Saint-Paul until September
Emily Chung | Jun 28, 2023

The first hydrogen-powered train in North America is taking riders on a two-and-a-half hour trip through central Quebec this summer.

It's a demonstration that launched earlier this month to show how electricity stored as hydrogen can replace diesel fuel on railways; where installing electrified rails or overhead wires would be challenging.

Advocates for the use of hydrogen in heavy transportation say it could raise awareness and boost confidence in the emerging technology in North America.

The tourist train made by French company Alstom runs from Montmorency Falls in Quebec City to Baie-Saint-Paul — partway along the Train de Charlevoix route — on Wednesday through Sunday until Sept. 30, carrying up to 120 people in two rail cars.

...The same model of train, known as the Coradia iLint, has previously carried passengers in eight European countries...

Cuts in ship pollution may have added to global warming??

‘We’re changing the clouds.’ An unintended test of geoengineering is fueling record ocean warmth
Paul Voosen | 2 Aug 2023

Pollution cuts have diminished “ship track” clouds, adding to global warming

...The obvious and primary driver of {Atlantic fever} is society’s emissions of greenhouse gases, which trap heat that the oceans steadily absorb. Another influence has been recent weather, especially stalled high-pressure systems that suppress cloud formation and allow the oceans to bake in the Sun.

But researchers are now waking up to another factor, one that could be filed under the category of unintended consequences: disappearing clouds known as ship tracks. Regulations imposed in 2020 by the United Nations’s International Maritime Organization (IMO) have cut ships’ sulfur pollution by more than 80% and improved air quality worldwide. The reduction has also lessened the effect of sulfate particles in seeding and brightening the distinctive low-lying, reflective clouds that follow in the wake of ships and help cool the planet...

Pioneering wind-powered cargo ship sets sail (BBC)

A cargo ship fitted with giant, rigid British-designed sails has set out on its maiden voyage. Shipping firm Cargill, which has chartered the vessel, hopes the technology will help the industry chart a course towards a greener future. The WindWings sails are designed to cut fuel consumption and therefore shipping's carbon footprint...The Pyxis Ocean's maiden journey, from China to Brazil, will provide the first real-world test of the WindWings - and an opportunity to assess whether a return to the traditional way of propelling ships could be the way forward for moving cargo at sea. Folded down when the ship is in port, the wings are opened out when it is in open water. They stand 123ft (37.5m) tall and are built of the same material as wind turbines, to make them durable. Enabling a vessel to be blown along by the wind, rather than rely solely on its engine, could hopefully eventually reduce a cargo ship's lifetime emissions by 30%...

This new 'levitating' Chinese train will be the fastest in the world
World Economic Forum | Jul 29, 2021

China has unveiled a new maglev train capable of a top speed of 600 kph.
The top speed makes the train the fastest ground vehicle in the world.
The train uses electro-magnetic force, meaning it "levitates" above the track with no contact between body and rail.
At 600 kph, it would only take 2.5 hours to travel from Beijing to Shanghai, a journey of more than 1,000 km or 620 miles.
By comparison, the journey would take 3 hours by plane and 5.5 hours by high-speed rail.

Nova Scotia's lobster fleet well-suited to go electric, study finds
Michael Tutton · The Canadian Press · Posted: Sep 21, 2023

Province's fleet produces emissions equivalent to about 35,000 cars a year

...Brent Dancey, director of marine climate action at Oceans North, said in an interview Thursday the move to electric would be most efficient for new vessels, for which energy-efficient hulls could be designed to mesh with the needs of batteries.

However, he said boats that are currently operating could also be fitted for electric systems, especially when their diesel engines need to overhauled.

...Under the group's "simplified analysis" of the costs of a 12-metre vessel's propulsion system — assuming the boat would use about 260 kilowatt hours daily of energy — the price for a diesel engine would be $70,000, versus $170,000 for a battery-electric system.

But over time, operating and maintenance costs over 20 years for the diesel engine would be about $280,000, much higher than the roughly $85,000 for the battery-powered boat...

P.E.I. company excited by new report promoting electric lobster boats
Report says governments should set adoption targets and provide EV-like incentives
Nancy Russell · CBC News · Posted: Sep 25, 2023

In the report, Oceans North says the key to getting the shift going is for governments to set a 'market signal' by setting clear targets for emission reductions, as has occurred in the motor vehicle sector. (Roger Cosman/CBC)

A P.E.I. company that just launched a hybrid lobster boat is applauding a new report promoting incentives and targets for electrifying marine vessels.

AKA Energy Systems is hoping to launch its own all-electric lobster boat within the next year, following up on its work with hybrid vessels...

Researchers make surprising discovery about lifespan of EV batteries: ‘That was a shock’
Erin Feiger | September 19, 2023

...a study* done in March by Recurrent Motors Inc. — a Seattle-based battery analysis company — showed that overall, EV batteries are actually very reliable and long-lasting. In fact, they may last longer than the vehicles themselves.

The study took real-world data from 15,000 EVs of various makes and models in the U.S. By linking to the vehicles’ connectivity systems, the company took several battery readings daily, including charging activity, EV battery level, and estimated range.

The data showed that most EVs driven close to 100,000 miles still have at least 90 percent of their original range left...

"Electrification is efficiency".
The energy transition will reduce final energy demand (and primary energy too).
Here's the transition for transport 👇

EPA Proposes Endangerment Finding for Lead Emissions from Aircraft Engines that Operate on Leaded Fuel (News Release)
October 7, 2022

...“endangerment finding”... now obligates {US EPA} under the Clean Air Act to set new rules on what aircraft engines can emit.

“The science is clear: exposure to lead can cause irreversible and lifelong health effects in children,” EPA Administrator Michael Regan said in a statement. “Aircraft that use leaded fuel are the dominant source of lead emissions in our air.”

Now that the EPA has made its determination, the Federal Aviation Administration said Wednesday that it will move forward with rulemaking aimed at controlling or eliminating aviation lead emissions from piston-engine aircraft...

Whoa! Aeroplanes still use leaded fuels? How did that happen?

If I recall correctly, shipping industry is responsible for ~4% of global CO2 emissions (= Germany). Electricity increasingly powers ferries with shorter runs than ocean-going vessels, but sounds like ships (often with defined, shorter runs) are also adapting the technology. Typically, such vessels are equipped with backup generators that run on fossil fuels.

Never simple, though: when shippers moved to cleaner fuels recently, we learned that there was loss of clouds along shipping lanes, clouds that cooled...

Another plus of electricty: ships powered by electricity are much quieter--hopefully benefitting aquatic animals, corals to whales... (Hope right whales aren't losing noise cues of approaching ships?)

Montreal-based (saltie) shipping reps were first & most responsive to need for ballast management back in 1990s (to prevent transport of invasive species). Not all associations are as helpful, so kudos to Montreal!

CSL Orders First Fully Electric Battery Capable Self-Unloading Ship
Shipping Telegraph | 27/12/2023

Canada Steamship Lines (CSL), the Montreal headquartered ship owner and operator of self-unloading vessels, has announced a 20-year strategic partnership with Australian-based Adelaide Brighton Cement (Adbri) to build and operate the world’s first fully electric battery capable self-unloading vessel..

..approximately 50% of the vessel’s energy requirements will be provided by a combination of shore power and battery energy storage, with plans to install sufficient batteries in the future to allow 100% electric operations.

...Louis Martel, CSL president and chief executive, explained: “Developed in line with CSL and Adbri’s shared decarbonization vision, this groundbreaking vessel will initially run on a hybrid diesel and battery system, replacing 25% of diesel with electric power and lowering Scope 1 emissions by 40% compared to Accolade II,” and he adds that “By 2031, we aim to run the ship entirely on electric power, further reducing Scope 1 emissions to less than 10%.”...
