Their choice of president will, in part, determine the shape of U.S. climate policy for the next four years.
The Democrat and Republican parties — and their respective nominees — have spelled out radically different visions for the future of American energy and emissions reductions, as well as the country's participation in international efforts to tackle climate change.
The official party lines are expressed in the Democratic and Republican "platforms," the U.S. equivalent of a manifesto. Clinton has laid out a detailed plan for U.S. energy and climate policy on her campaign website. Trump outlined his own vision during a speech on energy in North Dakota.
Both candidates have also made various scattergun comments on the subject during their campaigns and careers.
Clinton and Trump have also announced who will be joining them as their respective vice presidents. Tim Kaine, senator for Virginia, will join the Democratic ticket, while Mike Pence, governor of Indiana, will join the Republicans.
Carbon Brief has collected the climate and energy views of the candidates, their vice presidents and their parties' platforms in an interactive grid. This will be constantly updated as the election approaches.
