- I live in a small apartment block that is very insulted and has a lot of natural light
- don't own a car and use bike / public transport
- work 100% remote
- I compensate CO2 when flying, even when for business
- I try to have a minimal set of possessions, and buy second-hand if possible (and am really aggressive about ad blocking, don't watch commercial TV)
- I got a vasectomy to not have children
- I try to write and engage in social media about it, read the primary literature
- Donate to reforestation / tree planting initiatives
But it's all bullshit isn't it? I doesn't change a damn thing. The fixation on the idea that individual consumer behavior will make a noticeable impact is laughable. The only way to make a difference is by changing the companies and business that pollute in the first place, not the people who buy the stuff. And that means taxing, de-investing, subsidizing alternatives, and for the love-of stop subsidizing fossil fuels. But that's never going to happen.
I mean even putting a stupid sail on cargo ships would cut down pollution more than the CO2 anything you and I could ever do. Or if we hike up the prices of transport considerably (so fruits from bloody Africa don't cost 20 cents in Northern Europe) we can change our entire logistics pipeline.
