It is difficult to convince people that lowering their standard of living or paying more for renewable energy is a good thing. Especially when countries far away (China and the US) stand for such a high proportion of the CO2 emissions that your own contribution seems negligible. In the last couple of days both the US and China have taken a step in the right direction by announcing long term plans for cutting emissions in order to reduce the effects of climate change. Hopefully, this will convince people that change is on the way and that we should all be part of it.
