The best consumption for the climate is the one we don't engage in. Most of us still have room for maneuver when it comes to reducing and avoiding unnecessary purchases. We should make use of it!
The bottom line is that we can't or don't want to avoid consumption completely - and buying decisions are part of our daily lives. That's why it's best not to make them somehow, but to make them consciously and with our own values in mind. Because that way we can use our money like a political voice for a good future. Voting by receipt!
