A quick look at the graph in this Times Report shows the carbon dioxide CO2 emissions for the US, European Union, China and the Rest of the World in 2020. For the EU it is about 3.0 billion tons of CO2 emissions, for US it is 5 billon tons, for China 10 billion tons and the Rest of the World 16.0 billion tons. What this tells us is that a lot will depend on not just China, but India and other countries such as Brazil, Mexico, Indonesia in the developing world for how much CO2 emissions can be reduced to tackle climate change and other environmental problems. 

For that 16 billion tons in the rest of the world reduction will depend on renewable supply and technologies to do it, rapid growth of economies in India and other countries to generate the resources and technology initiatives to get a shift from coal. Meanwhile it is a choice between having electricity for homes in rural areas in India or not. This is where bright spots such as solar technology in India that are giving quantum leaps for renewable solar energy with new technology cutting cost in successive waves of development can play a part.
