UN Knows Industry/Energy Pollutes

We have hundreds of millions of cows, don't we? a 4-stroke engine is small change. a 2-stroke engine is literally thousands of times filthier than a 4-stroke engine. Industrial pollution is thousands of times filthier than automotive pollution, is it not? The world has ~400 nuclear plants and thousands to tens of thousands of coal burning plants, and as many major factories or more.

Cars are minor, immediately economically visible markers.
