We call an argument rational, if it is based on measures. We act rational if we use those arguments in order to fulfill a self-interest. Yet, most things can‘t be measured. The often used Carbon Footprint for example, for any product, is rather an estimate instead of a real measure.
- Where does a supply chain for a product start?
- Do you take into consideration that at one point maybe trees had to be cut down in order to built the production site?
- Where to stop measuring? When it‘s not used anymore? Or at landfill?
We treat the impact of carbon on the climate analytically. Yet, it’s complex. Complex problems can‘t be solved analytically.
Believing that rationality exists in this way is a trap that wins most arguments. When we address the future of humanity, rationality is not enough.
