2020 presidential candidate Beto O'Rourke has outlined a highly detailed strategy for tackling climate change. At the crux of his $5 trillion proposal is the goal to achieve net-zero carbon emissions by 2050.
The big picture: This is O'Rourke's first major policy proposal. It takes an aggressive position on tackling global warming through executive action and legislation. His plan calls climate change the "greatest threat we face."
