Here is what I try: Host stuff in data centers that are operated by 100% Renewables, use hardware efficiently (virtualisation, ARM boards for simple tasks), fly not more than every 2-5 years, eat meat only once a week, use public transport as much as possible (easier said in Europe I assume), take cold showers whenever I have the courage, make sure my bank does not invest my money in fossil fuel or military projects, ... Politicians and also scientists still avoid to say this aloud but without sufficiency there will be not enough change. The window of efficiency has passed.
