Put this four-point plan into action and we can drastically cut global warming pollution. We have solutions in hand right now to drastically cut global warming pollution. Act now -- put clean, innovative energy technologies to use, and enact policies to encourage their rapid, widespread adoption -- and we can stop global warming in its tracks. Instead of nearly doubling U.S. global warming pollution by 2050, we can cut it by more than half using today's technology. And with the proper incentives in place, even more innovative solutions will emerge along the way, leading to even bigger reductions. This four-point plan is how we get started. Step 1: Boost Energy Efficiency.
