Keep in mind that personal carbon footprint is an invention of fossil marketers, and a lot of that is intentionally ineffective distraction. You can't build long-distance UHVDC power lines yourself. Really big changes can only be done at the state level. If you need a new car, an EV is still better than a new gas car, but having public transport and rail network is even more efficient. But you can't create a properly functioning well-funded transport system yourself. As an individual the best you can do is insulate your house, and if you need heating, get a heat pump. Domestic heating/cooling energy use is significant, and needs to be electrified before it can be decarbonized. Some things like rooftop solar panels + batteries do work, but that is offloading switching costs to individuals, while the fossil industry is still getting subsidies. Grid-scale solar farms and storage are more cost effective. Wind farms are even better, but you can't build ones tall enough in your backyard.
