Yes, it is tokenism but what with "flightshaming" and F- e they have to be seen to do something and , rationally, they have the money to fund effective carbon offsetting.
I actually think the FIA and Liberty have missed trick here. With the logistics being 70% or more of the CO2 footprint a ruthless cut back in number of trucks, and aircraft size would have looked very positive and also forced a big cost reduction on the teams.
A lot of it is about perception and F1 is not on a winner right now.
Speaking of perception I can easily wind up my classic car finds by telling them if Classics keep leaving shows belching out raw hydrocarbons into every bodies face they will become socially unacceptable soon. I point out most classic engines from 60's / 70's have later versions with emisions controls and they will probably have to accept installing that emissions gear to be able to drive on roads one day.
