wind - how little to off set ?
Assuming that methane gas is considered to be a major green house gas can I assume that if I give up F--ting my flying will have a neutral carbon foot print ?
If so how much less would I need to degas if if fly a Gazelle than say an R22.
Seriously now - climate change is a problem and will be taken more seriously by all when it is seen to be tackled in less of a tax raising type way.
