The Trump administration has formally notified the United Nations that it will withdraw IN 2020, the United States from the Paris Agreement that was signed by former President Barack Obama in 2015. The United States, the world’s largest historic greenhouse gas emitter, has vowed to boost U.S. oil, gas and coal industries to accelerate U.S. growth. Several U.S. governors, mayors and other local leaders have however reaffirmed their commitment to the Paris Agreement in the absence of federal leadership on the issue.
