United States will miss Paris climate targets without further action, study finds

Even if the United States implements all current and proposed policies, it would miss its 2025 target by as much as 1.5 billion metric tons of carbon dioxide per year—roughly 20% of the nation’s total emissions, according to the analysis published today in Nature Climate Change.
Although the U.S. path to meeting its promises is uncertain, it has made further progress than some other countries, says Bill Hare, a climate scientist and CEO of Climate Analytics.
