So, was waiting until I was sufficiently quiet (bored) at work to reply to this!
Answering your initial question first.
I very much try to lessen my impact in as many of my day-to-day choices as I think I can.
I’ve been on a green energy tariff for a while now, first with Bulb, and now with London Power (https://mylondonpower.com/), which also reinvests any profits into (admittedly vague) ‘green’ projects in London.
I do ‘offset’ every month with Ecologi, which pays for a number of trees to be planted. (well aware of various criticisms of off-setting but I’d rather plant some trees than nothing)
Whenever I have to replace something at home, I try to find the most energy efficient if it’s an appliance, or the most recyclable/eco-conscious if it’s a scrubbing brush or cleaning product for example. Similarly, I only use rechargeable batteries and LED lights.
And that’s the way I feel I make the most difference to my personal footprint - just seeing if I can do better every time I buy something new/change some aspect of my life.
Relatedly - I discovered this site the other day from a Positive News article (About us - Trainhugger) which I intend to use next time I book train tickets. Tree planted for every ticket (partnered with the Royal Forestry Society) and a third of revenue into eco-initiatives.
All of that said though, I’m totally with a lot of the sentiment in this thread that I know I’m doing X or Y, but I’m a drop in a drop in a drop in the ocean compared to Shell, BP, Coca Cola, Nestle, etc etc etc.
So I hope that enough governments around the world stop being cunts (and in that respect I will continue to protest and write to my MP and so on), but I’ll at least do what I can - more from a moral view than thinking it will have a practical effect I suppose.
