• Sustainable aviation Introduction (video)
Not zero emissions
• More sustainable travelling will be needed in the post-pandemic era
• The aviation sector should re-consider its strategy to reduce climate impact, Manchester report suggests
• Greener air travel will depend on these emerging technologies
DIRECT AIR CAPTURE
Claims that Direct Air Capture (DAC) is ‘100% green’ are misleading. DAC will not eliminate a flights actual CO2 emissions, and will add additional CO2 if DAC uses fossil fuel electricity.
• Researchers pull carbon out of the sky and convert it to instant jet fuel, reshaping aviation for good
• United Airlines aims to suck carbon dioxide from the friendly skies
• United Airlines will invest in carbon capture en route to net zero emissions
• Businesses aim to pull greenhouse gases from the air. It’s a gamble.
• Hybrid-electric plane that ‘scrubs’ exhaust before ejecting it into the atmosphere could reduce emissions of harmful nitrogen oxides by 95 per cent, MIT engineers claim
“SUSTAINABLE” AVIATION FUEL
The aviation industry uses marketing greenwash and accounting tricks to mislead you into thinking that actual flight emissions from ‘Sustainable’ Aviation Fuel (SAF) are a fraction of those from fossil jet fuel. A jet never burns pure SAF, so a common 50:50 blend with fossil jet fuel doubles claimed emissions. And actual flight CO2 emissions are additionally more than claimed, by the amount of CO2 drawn down in making the fuel. Furthermore SAF still creates non-CO2 emissions twice as warming as actual flight CO2 emissions.
• As the aviation industry recovers from one crisis, it is looking to the next: climate change
• Neste and Avfuel create strategic partnership for sustainable aviation fuel
• Boeing vows to develop planes able to fly on 100 per cent sustainable fuel by 2030
• Boeing wants all its aircraft to fly on sustainable fuels by 2030
• Future fuels change the balance of power
• Biofuels conference
When all sectors need to reduce their emissions to zero, the aviation industry buys/offsets the reductions of others in order to grow its own emissions.
• 4AIR launches as the first emissions reduction solution provider focused solely on private aviation
• Shell, BP, and Easyjet: The big polluters designing the rules for voluntary carbon offsets
• Implementing the Carbon Offsetting and Reduction Scheme for International Aviation
NET ZERO 2050
• Signature Aviation recognized with a prestigious ‘A’ score for its efforts to combat climate change
• Qantas and BP unveil strategic partnership to reduce carbon emissions
• Heavy industry, transport sectors to align on net-zero climate plans
CHANGING FLIGHT ROUTES
• Surfing the breeze: Transatlantic aircraft could use 16 per cent less fuel by hitching a better ride on the jet stream, study claims
• DFW airport wants to cut emissions to zero by 2030, but can it do it? And what does that mean?
Not zero warming
Burning hydrogen fuel still creates non-CO2 emissions twice as warming as avoided flight CO2 emissions, and generating enough CO2 emissions-free hydrogen will use more than all the renewable electricity currently generated.
