Because money. People can’t afford to upgrade their lifestyle to solar panels and organic foods and a new electric car. Corporations aren’t going to stop making things out of plastics and poisons if it costs them more profit.
It is not going down, but at least it stopped going up in last 10 years. So something is happening.
It will take time. I drive 10 yo ICE car and I can't afford new ev car now, but hopefully before my current car will die in 5+ years, second hand ev market will exist.
Most emissions are caused by rich people. Quite frankly as soon as you forget about the car, the rest is rather cheap. Solar panels powering a home are not crazily expensive and organic food staples are also not that much more expensive then the conventional competition. Electric cars are expensive, but the proper choice is to try to live car free anyway. A bicycle is cheap after all.
Anybody who actually is emitting more then the global average can live in a way that massivly reduces their emissions and afford to do it. Not to zero, but to a point, where it is absolutly reasitic to demand companies and governments to push for the rest.
