Leadership in fighting climate change? Cmon' every EU-country is better at fighting climate change than the US. Denmark has at least 50% of their energy coming from their huge wind farms. Norway has a huge network of chargers for electrical cars, tax cuts for electrical cars and Sweden is huge in all sorts of environmental savings.
In Sweden you can't even order a fucking burger without seeing how much CO2 that produces and ads for vegetarian burgers that are better for the environment.
If you really think US is good at all at fighting climate change, you should really come to the EU and watch us recycle. Even during the recent terror attack in Stockholm there were people recycling.
