Battery-Powered Plane Crashes in Norway as Country Tries to Ditch Fossil Fuels
https://www.theverge.com/2019/8/15/20806776/norway-electric-plane-battery-crash-fjord-jet-fuel-avinor

An all-electric battery-powered plane has crashed into a lake in Norway, in what is a setback for the country’s attempt to move away from fossil fuel-powered flight. Reuters reports that the Alpha Electro G2 plane is owned and operated by Avinor, Norway’s state-run airport operator, and was being flown by its chief executive, Dag Falk-Petersen, when it crashed. On the day of the incident, the CEO was in the process of giving flights to members of the Norwegian government, and junior government minister Aase Marthe Horrigmo was on board at the time. Both escaped from the crash unharmed.

... it’s currently unclear exactly what caused the crash. Forbes reports that the pilot said he lost all power from the engines as he was approaching the airport to land. He estimated that the plate was travelling at around 43mph when it hit the water.

The plane was an Alpha Electro G2 manufactured by Pipstrel, and it’s the first electric two-seater aircraft to have been approved for commercial production, according to Forbes. It has a range of around 81 miles, and a maximum flight time of an hour. Reuters reported that Norway first started testing the plane last year. ...

Intact airplane — hardly a ‘crash.’  More like an ‘off-airport forced landing mishap.’  ;)
It happens.
People who say it cannot be done should not interrupt those who are doing it.

Passengers could soon be flying on planes fuelled by waste gases from steelworks.

The plan involves using the gases from Tata's Port Talbot plant, which developers believe could be used for thousands of flights a year.

Tata, along with Neath Port Talbot council and American bioengineering firm LanzaTech are working on the plan.

Virgin Atlantic worked with LanzaTech last year to fly from Orlando to London powered by recycled carbon jet fuel.

Waste gases are an unavoidable part of the industrial production of steel and it is thought it could generate 30 million gallons of biofuel for the aviation industry every year.

Looks like a good idea.

Every time I settle down to write a travel article lately, I feel like a canary in a coal mine, whistling denial. Perhaps, if my work achieves any kind of posterity, it will be in a museum of defunct pastimes from the Extinction Age. Amid the exhibits of hamburgers and combustion engines will be a gallery of press cuttings from the era of mass tourism, fossils for future, static generations to gawp at, wondering at the excess of their deluded forebears, who continued jetting around the planet even as that planet withered and burned before their eyes.

Prince Harry wants to make tourism more sustainable — is he a hypocrite?
https://www.cbc.ca/news/world/royal-fascinator-prince-harry-air-travel-prince-andrew-jeffrey-epstein-1.5272019
Quote
Goodman said focusing on individual actions is just the place to start in efforts to develop fundamental structural changes that lead to carbon-neutral economies, and suggested that people like Harry should take a close look at their own actions, too.

"Rich countries and celebrity individuals need to get their own houses in order, namely because they owe a much greater debt, based on their historical carbon emissions and extravagant lifestyles, compared to others across the globe."

Whatever Harry does, it seems unlikely his private jet travel to the south of France and Ibiza this summer will quickly be forgotten. Author and biographer Penny Junor said it will come back to haunt him.

"However many commercial flights he takes now, there will always be that little paragraph saying that he was heavily criticized for taking four jets in 11 days."

Heathrow Airport warns climate activists against flying drones
https://www.dw.com/en/heathrow-airport-warns-climate-activists-against-flying-drones/a-50370788
Quote
London's Heathrow Airport on Tuesday said it is working with law enforcement to ensure drones are not deployed by climate protesters to disrupt air traffic.

"We have in place the dynamic risks assessment programs which are carried out by airfield and security experts and at no time will safety be compromised," according to a statement issued by airport authorities. "Alongside drone detection capabilities, we will mitigate the impact of this illegal action and operate in a way that is safe at all times."

Protesters plan to fly toy drones near the airport in a bid to halt flights and pressure the government to do more on fighting emissions from the aviation industry.

Aviation’s black box: Non-disclosure agreements, closed doors and rising CO2
https://www.climatechangenews.com/2019/09/12/non-disclosure-agreements-closed-doors-rising-co2-uns-aviation-body/
Quote
The International Civil Aviation Organisation (Icao), headquartered in downtown Montreal, has been charged with reducing the rising carbon emissions from international flight – an enormous commercial, technical and public relations challenge for the industry.

Between 2013 and 2018, aviation sector emissions grew from 710 to 905 million tonnes of CO2, according to the latest estimates by the International Air Transport Association (Iata). Flying now generates just under 3% of global emissions, roughly the same as Germany. Icao’s own forecast anticipates emissions to increase by up to 300% by 2050 under business as usual.

Climate advocates say oversight is critical in a matter of such high public interest. But through interviews with delegates and observers, Climate Home News has found scrutiny is restricted and key information protected by non-disclosure agreements.

Climate change: Germany's conservatives mull doubling air travel tax
https://www.bbc.com/news/world-europe-49719276?intlink_from_url=&link_location=live-reporting-story
Quote
Germany's ruling conservatives have proposed doubling taxes on domestic flights, as part of a wider package to cut CO2 emissions.

The decision was taken by the leadership of the Christian Democrats (CDU), who form a coalition with the Christian Social Union (CSU) and the Social Democrats (SPD).

Tax of €7.38 (£6.5; $8.1) per ticket is currently levied on domestic flights.

Connecting flights that are part of long-haul journey will be exempt.

OPINION: INSTEAD OF FLIGHT SHAMING, LET’S BE THOUGHTFUL AND SELECTIVE ABOUT ALL TRAVEL
https://ensia.com/voices/flight-shaming-flying-travel-carbon-co2-emissions-flyless-aviation-cars-trains/
Quote
In early June 2019, the three of us were having a conversation at the University of British Columbia when Lior expressed some dissatisfaction about an activity at his kids’ school that suggested airplane travel is bad for the climate. In fact, he said, per passenger mile, air travel carbon emissions are of the same order of magnitude as other modes of transportation, so it doesn’t matter covering climate nowmuch whether you drive or fly. However, he further explained, since larger planes are more carbon-efficient and since takeoff and landing are particularly costly, the carbon efficiency of air travel significantly depends on distance. In other words, short-haul flights tend to be inefficient relative to driving, while transcontinental flights are very efficient.

The other two of us looked at each other, bewildered. We had both calculated our carbon budgets and seen that a single transatlantic flight would blow our annual carbon budget. Many prominent climate scientists were touting #flyingless. But was Lior right? Had we been drinking flight-shaming Kool-Aid?

That evening, we looked up the numbers on Wikipedia and found, to our surprise, that Lior seemed right! At least to some extent. We tweeted about it to let the experts weigh in.

The key point about air travel is just how easy it makes emitting lots of CO2.  How many people are going to hop in a car and drive from Vancouver to Toronto for a conference or holiday?  Google Maps puts that at 40 hours of driving, then another 40 hours to get back home again.  The per capita per km emissions flying and driving may be similar but that's beside the point when almost no one is going to consider driving a journey that is easy in a plane.

Europe’s Airports Step Up To Climate Change Challenge

This past June, ACI EUROPE announced a resolution for its 500 members to reach net zero carbon emissions by 2050, for the carbon emissions under their control. That commitment has been undersigned by 203 airports to date run by more than 47 airport operators across 42 European countries, representing 64.3% of European air passenger traffic. Nine airports have signed the commitment over the past 3 months: Aberdeen, Glasgow, Liege, Luxembourg, Malta, Salzburg, Southampton, Turin and Toulouse-Blagnac. More are expected to join the pledge in the coming months.

There are already three net zero airports in Europe: Luleå, Ronneby and Visby - operated by the Swedish airport operator, Swedavia. Swedavia aims to achieve zero emissions for all its airports by 2020, including the hub at Stockholm-Arlanda.

  1% of English residents take one-fifth of overseas flights, survey shows

https://www.theguardian.com/environment/2019/sep/25/1-of-english-residents-take-one-fifth-of-overseas-flights-survey-shows

 Quotes:
The figures, published in a Department for Transport survey, also reveal that the 10% most frequent flyers in England took more than half of all international flights in 2018. However, 48% of the population did not take a single flight abroad in the last year.

Environmental activists said the new figures showed the UK could cut air traffic and emissions without affecting ordinary holidaymakers.

Leo Murray, director of innovation at 10:10 Climate Action
What we need to do is target a minority of problem flyers and stop them from taking so many flights,” he added.

The findings are based on responses from more than 15,000 English residents who participated in the 2018 National Transport Survey and were revealed to the Guardian following a Freedom of Information request.

There is currently no country in which travellers pay an escalating levy on each flight they take in a year.

Chris Stark, the CCC’s chief executive
He argued that the UK should take a leading role in cutting emissions from the sector, rather than wait for more comprehensive international agreements to be struck.

… However, 48% of the population did not take a single flight abroad in the last year.
This suggests 52% of the residents of England did fly abroad during a 12-month period.  Frankly, I don't believe it; most people don't hardly every fly.  Maybe 52% of those who flew even once during the year traveled abroad.  The end of my speculations.

From the internet:
Quote
“An estimated 70 per cent of all flights in 2013 were taken by just 15 per cent of the [English] population, with 57 per cent of the [English] population taking no flights abroad”

In March 2014 the survey asked a random selection of 1,000 adults in Great Britain how many trips by plane they’d taken in the last 12 months. 52% hadn’t flown at all.

We asked the Department for Transport, which designed the survey, about this claim. It said a more precise estimate is that the 15% of adults in Great Britain who made 3 or more flights (our frequent fliers) made 71% of flights from March 2013 to March 2014.

The same survey asked about what types of flights people had taken. 7% had flown domestically, …
Now, with some more data: boy, more people fly then I expected.  (I all but stopped 30 years ago - about 6 within-the-US flights [all but one round-trips] since then, none in 5 years.  I guess I presumed others stopped too.  :'()  And, most English flyers leave England.  (Duh, I think: England is, after all, the size of Mississippi.)

Ban air miles to combat climate crisis, recommends UK research
Quote
Air miles programs should be banned and a levy on frequent flyers implemented in order to reduce carbon emissions from aviation, according to new research.
...
"Flying is a uniquely high-impact activity and is the quickest and cheapest way for a consumer to increase their carbon footprint," the report says.

Air miles programs encourage people to take extra flights to keep up their "privileged traveler status" and should be banned, according to the report.

So-called "mileage runs" are a common way for travelers to top up their points in order to maintain access to perks such as priority boarding.
An air miles levy would be based on the number of miles flown by each passenger, penalizing those who fly the most while leaving the majority of people unaffected.

Research shows that 15% of the UK population take 70% of flights, and these travelers -- who tend to be wealthier and less price-sensitive -- would shoulder most of the burden. By way of comparison, 50% of Britons don't fly at all in any one year.

Landing (and emergency diversions) are the most difficult parts of a flight regime.  Automating these tasks, and introducing the technology as a rarely-used safety enhancement, makes it a desirable feature that is likely to be more widely adopted in small aircraft.

Garmin mentions their Autoland software can enter a holding pattern, if needed to reduce speed.  Add takeoff and flight commands — and the ability for Air Traffic Control to interact with the plane — and fully autonomous flights are a given.  ATC today assigns flight routes and altitudes for aircraft on instrument flight plans, and establishes published airport approach and departure patterns.  Now envision a computer-controlled ATC system, which is certainly in our future....

At a minimum, one hopes it inspires/shames other airlines into doing the same.

EasyJet 1st Airline In World To Go Carbon Neutral — Starting Today
November 19th, 2019
Quote
In a corporate press release, EasyJet today announced that as of today all of its flights will be carbon neutral. EasyJet has a total of 331 airplanes and will become the first major airline in the world to operate a fleet that is fully net-zero carbon. What this means a little more specifically is that EasyJet will have balanced all of its carbon emissions via carbon removal efforts.

Furthermore, this is an “interim measure,” as EasyJet plans to go beyond this in the future. “We will continue the push to reinvent aviation for the long-term, including the development of sustainable fuel and electric flying,” EasyJet writes.

The airline expects to spend £25 million ($32.4 million) over the next year compensating for every tonne of CO2 emitted from fuel used for EasyJet flights. The goal is to make sure there is one tonne less in the atmosphere to counter the added tonne. EasyJet will either reduce CO2 by physically removing it from the air (planting more trees) or by avoiding the release of more CO2 (for example, by installing wind or solar power plants). ...

That "carbon neutral" is just another marketing ploy.
For every plane and every flight Easyjet is pumping tons of extra CO2 (and other shit) into our atmosphere. So consumerists can have a weekend in Paris.
Now Easyjet wants them to not feel bad about it. This "carbon neutral" lie will be eagerly swallowed.

Carbon offsetting is not carbon neutral. It is 'kicking the can down the road' so our consumerist systems don't have to change.

Where are the airballoon and zeppelin tickets? They have a huge area to put flexible solar panels on.

While it is a good sign that leadership at Easyjet is acknowledging the issue of climate change, their method of addressing the situation is already dated.

There is best practice corporate guidance currently in development that will exclude the use of carbon offsets as a means to claim 'carbon neutrality' or 'net-zero' emissions. The working group is currently getting feedback (although they've indicated the question of carbon offsets counting isn't on the table) and is planning on having the document finalized for use by corporations by COP25.

I believe many within and outside the industry will be thankful that someone is making this clear as carbon offsets have always been messy with studies indicated that their impact is often not what they are certified to in the long-term. Offsets for those not fully familiar consider what is the reduction impact of this activity from the baseline, where the baseline is usually the legal minimum. Even then, the long-term impacts of the superior activity can be short-term in nature (i.e. read about the issues around cook-stoves in developing countries or REDD forest protection projects in Brazil and elsewhere)

What will be allowed under this new schema is activities that directly remove GHG (mostly carbon) from the atmosphere including direct air carbon capture and to be determined forms of reforestation and soil sequestration (i.e. regenerative agriculture). In these cases, there will be a 1 for 1 balance of carbon emitted and pulled from the atmosphere. Whether companies can buy these 'credits' from others or have to do it within their value chain is up for debate.

Easyjet and many other companies (see Microsoft, Google, etc) will all have to walk back their carbon neutral claims starting in 2020 or be deemed greenwashing. Carbon Neutral / Net-Zero under this definition will likely be near impossible for some industries - but I think this is the reality we expected - carbon neutral and net-zero aren't easy - they take fundamental restructuring of how the economy works. You can't simply buy your way out of this one.

Easyjet's advisors on this really should have known better. They've put the company in a tough spot PR-wise and financially with a big capital outlay that would have had more impact going to R&D into bio-fuels and electrification.

(I advise a company that is now having to develop a strategy about how to best walk back their long-term carbon neutral commitment if you are wondering the source of this information).

Could you expand a little re. the company you're advising? I'm curious as to what they produce, the offsets they're considering, and the approximate size of the concern.
Forcing corporations to eschew their greenwashing claims has to be a positive, even if it does kill off a few marginally effective projects.

The offsets they considered were limited to those with only the most robust calculated impact - in this case landfill gas to energy projects that were not otherwise mandated by regulations (we had concerns with leakage for other project types). The total impact of their direct operations is relatively small when compared to others at less than 100,000 MTCO2e.

I would be a bad consultant if I named my client on a forum, so you'll have to respect my passing on that question :)

Sorry - I never intended that you dox yourself or your client. My interest was in your method and the relative size of your project.
Thanks

Flight shame: People are quitting flying because of climate change | CNN Travel

...
The campaign sparked a wave of social media posts showing people traveling by train, accompanied by the hashtags #flygskam and #tågskryt, which mean "flight shame" and "train brag" in Swedish.

According to a survey released in May 2019 by Swedish Railways (SJ), 37% of respondents chose to travel by train instead of plane where possible, compared to 20% at the start of 2018. An SJ spokesperson said: "Rail travel is soaring thanks to climate fears."

Domestic passenger numbers in July fell by 12% compared to the previous year, according to Swedavia, a company which operates Sweden's 10 busiest airports. ...

Harbour Air in Vancouver, BC completes the first test flight of its electric converted passenger/cargo airplane.
Quote
Harbour currently has 14 six-passenger DHC-2 Beaver aircraft, many of which are equipped with Pratt & Whitney PT-6A turbine engines that burn about $300 worth of jet A fuel per hour. By contrast, the eBeaver packs enough battery life to fly about 100 miles at a cost of around $10 to $20 worth of electricity.

E-planes have a very limited range compared to ICE-powered models because lithium-ion batteries have less than 5 percent the energy density of gasoline or jet fuel. However, 100 miles is enough for many of the short seaplane hops around Vancouver's lower mainland. The distance between Vancouver and British Columbia capital Victoria (downtown to downtown) is 58 miles and takes about 30 minutes by plane, while the same trip on a ferry can run over four hours including driving time and waiting. (Also, as your author can attest from brutal experience, the flight is a lot less boring.)

Despite the range challenges, electric planes have big advantages over ICE-powered models. That includes lower maintenance and operating costs, no need for fueling infrastructure (other than chargers) and easier boarding on local routes. "We are proving that low-cost, environmentally friendly, commercial electric air travel can be a reality in the very near future," said Ganzarski.
