I understand the strong desire to help the environment, but why lead with that? I think it's become apparent that the average person doesn't really care about the environment. People do care about maximum convenience and minimal cost , which usually leads to waste. We should try harder to create a system that aligns the incentive of taking care of the Earth than we try to force people to care about the environment. Remember, if your reasoning is that "if people would just XYZ", it's bad reasoning.
According to page 116 of the report of this EU survey: https://europa.eu/eurobarometer/surveys/detail/3752, Sweden and Denmark have climare change as their number 1 and number 2 most important topics to be addressed in the European Parliament respectively. It makes sense to extend that to the OP which is norwegian and say that a lot of the target audience probably cares
I do however agree that making the cheapest/best solutions also be good for the environment would be ideal.
