“I will make a bet today that what happened to the car regulation will happen to the SAF [Sustainable Aviation Fuels] regulation in Europe,” French energy giant TotalEnergies CEO Patrick Pouyanné predicted at the World Economic Forum in Davos earlier this month.

Carmakers provide a model on how to get the EU to backtrack. The bloc mandated that no CO2-emitting cars could be sold from 2035, essentially killing the combustion engine and replacing it with batteries (possibly with a minor role for hydrogen).

But many carmakers — allied with countries like Germany, Italy and automaking nations in Central Europe — pushed back, arguing that the 2035 mandate would destroy the car sector just as it is battling U.S. President Donald Trump’s tariffs, sluggish demand and a rising threat from Chinese competitors.

In the end, the European Commission gave way and watered down the 2035 mandate, which will now only aim to cut CO2 emissions by 90 percent.

Aviation demands

The aviation sector has a similar list of issues with the EU. It is taking aim at a host of other climate policies, such as including aviation in the bloc’s cap-and-trade Emissions Trading System and intervening on non-CO2 impacts of airplanes like contrails — the ice clouds produced by airplanes that have an effect on global warming.

Brussels introduced several regulations over the last 15 years to address the growing climate impact of air transport, which accounts for about 3 percent of global CO2 emissions. Those policies include the obligation to use sustainable aviation fuels, to put a price on carbon emissions and to take action on non-CO2 emissions.
