One long distance flight (roundtrip) per year has about the same CO2 equivalent as going from vegan to "normal" meat consumption (namely about a quarter of the average citizen's CO2 footprint). Draw your own conclusions, inform others.

One way is to reduce your climate impact to 2 tons / year and spread the word.

well I already don't own a car (last mile vehicle is enough for my use), and follow a mediterranean diet, avoid waste, etc

But e.g. as much as I try to avoid single use plastic, my limited useage is not going to do much vs just banning / heavily taxing them.

So my question was more : what can I do to actually make the lines move.

I answered this before but can't find my post (is there an easy way to search your own comments?)

Basically I said put pressure on your politician. As an individual you can't do much, a politician is the person to make things happen - it's their job! - so pressure them.

I'm currently doing this to my own (in the UK). They seem to be struggling rather pitifully to understand the difference in priorities between Brexit, and a Catastrophe of Human Making aka climate change. Well, FWIW I'll keep pressuring them.

Or nothing at all. Whichever suits.
