"President Trump late Thursday replaced an executive order signed by former President Obama that sought to reduce federal agencies’ energy use and greenhouse gas emissions.
The revocation came as part of a late-night executive order that instructs agencies to set their own goals for efficiency and “prioritize actions that reduce waste, cut costs, enhance the resilience of Federal infrastructure and operations, and enable more effective accomplishment of its mission.”
Obama signed the original order in 2015, with a goal of reducing the federal government’s greenhouse gas emissions 40 percent in a decade. It asked agencies to reduce buildings’ energy use by 2.5 percent per year, use clean energy for 25 percent of their energy needs and shrink water use by 36 percent."
