Seems pretty straightforward as far as fact checks go. The Paris Accord says nothing about coal, it's all about emissions. We could increase coal use too if we wanted to, as long as our emissions go down. So really, the statement from Trump is true but misleading.

"It" doesn't stop us, we negotiated this as part of a global agreement to reduce emissions. Because we're the world's biggest source of emissions and also the richest, our responsibility is greater than that of a developing country like India that can't afford new nuclear plants and whose citizens can't afford solar roofs.
