To be frank, the U.S. federal government has not really been a major leader in greenhouse gas reductions. Most of the heavy lifting so far has been done by states and local governments along with businesses. As the article points out, there will be more pressure on these entities to get more aggressive with greenhouse gas reduction in the absence of federal leadership.
If the current occupant of the White House loses the election, which is looking likely, the U.S. will probably stay in the Paris Accord. However, in the coming year of uncertainty, many are looking for alternative ways to advance a global fix to the greenhouse gas problem without U.S. leadership. The withdraw is another example of the U.S. walking away from leadership positions on the global stage.
