Uhh... no. Air travel for example was 2.5% of global CO2 emissions in 2018. This kind of nonsense is almost as bad as denialism because it pushes the false "we can't radically cut CO2 without abandoning all modern technology!" narrative.
Yes, we absolutely can. Coal burning and only coal burning accounts for a whopping 61% of global manmade CO2 emissions. That means oil, gas, and agriculture are responsible for less than 50% of global emissions combined.
Phasing out coal for electricity generation in favor of renewables and nuclear is by far the #1 thing we can do. We could stop using airplanes entirely and it would make no measurable impact compared to closing even 10% of all global coal power plants.
The narrative should be that coal is the enemy. Keep it simple and bang the drum: coal, coal, coal. After coal there's a long tail of CO2 emitters and the next one to tackle is the next largest. That's probably oil for land and sea transport, which is far easier to replace with alternatives (mostly EVs) than aviation. By the time we get rid of >50% of coal power we might already have replaced a double digit percentage of the car fleet with EVs.
Air travel at 2.5% is not even worth bringing up.
