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.

Interesting statement. So where do we find all of these planes?

There is a shortage everywhere already.

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.

A Future Without Long-Haul Vacations

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.

From more intense wildfires to prolonged droughts, climate change is impacting the ecology of the American West. That’s got researchers in our region looking at a new way to fight some of these impacts: drones.

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.

And of course CO2 is not the only factor to be taken into account when comparing the climate effect of different modes of transportation:
