We don't know if the OP already has a fairly low carbon footprint, or has done all they can to reduce it.
Cumulative effort and reducing carbon footprints on many fronts is what we need.
Things like:
- Walk / Cycle where you can. Use public transport where you cant.
- Have your heating / AC lower.
- Stop using single use plastics.
- Eat less meat.
- Swap all your bulbs to low power equivalents.
- Take shorter showers.
- Turn off your work monitors / PC when you leave the office. (Assuming tech population here)
- Switch to a power provider that only uses 100% renewable power. (Like bulb in the UK)
- Support a charity that is planting trees or is fighting to save the rain forest.
- Donate/pay to have some charity/company do some carbon removal for you.
- Change your browsers default search engine to Ecosia (Bing results and they plant trees with the profits)
Lots of tiny things can be done now, with relatively little effort. In parallel with companies and researchers work on better carbon capture techniques.
