According to the statement above, the governors intend to recruit more states into the US Climate Alliance. Together, they aim to meet the same goals as the Paris agreement, including reducing emissions from 2005 levels and beating the targets set by the federal Clean Power Plan. As noted, the three founding states represent about 68 million people, a fifth of the US population -- who produce a fifth of the US GDP.



The group of city leaders, known as the Mayors National Climate Action Agenda (or, Climate Mayors) stated back in March they would resist Trump's efforts to roll back Obama-era climatae policies. Their statement today lists all 61 participating mayors -- including William Peduto of Pittsburgh, a city Trump mentioned in today's speech.
