UN's environmental assembly

United Nations Environment Assembly, 170 countries gathered to discuss sustainable consumption. According to articles, air pollution costs us $5trillion annually and so they have set an 80% reduction of fossil fuel use by 2050 goal. The 2015 Paris Climate Agreement said that 2/3 of the planet do not have access to controlled waste disposal, do you?

What could you do to reduce your fossil fuels use and help their 2050 goals? maybe walking, instead of driving?
