It wasn’t pertinent to my point. I was merely pointing out that coal is a huge problem.

Also, the United States is 15% of global emissions, not 28%.

Fair enough, the figures I found were probably older.

My point is the USA should fix its own problem before lecturing others. Other countries are far more advanced in renewables, time to catch up.
