Trump’s fossil fuel crusade confronts the climate faithful

Pulling out of the Paris climate agreement was not enough, an ex-aide to the U.S. president says on the eve of a summit in Brazil: “You have to potentially destroy it.”

President Donald Trump is no longer content to stand aloof from the global alliance trying to combat climate change. His new goal is to demolish it — and replace it with a new coalition reliant on U.S. fossil fuels.

Trump’s increasingly assertive energy diplomacy is one of the biggest challenges awaiting the world leaders, diplomats and business luminaries gathering for a United Nations summit in Brazil to try to advance the fight against global warming. The U.S. president will not be there — unlike the leaders of countries including France, Germany and the United Kingdom, who will speak before delegates from nearly 200 nations on Thursday and Friday. But his efforts to undermine the Paris climate agreement already loom over the talks, as does his initial success in drawing support from other countries.

“It’s not enough to just withdraw from” the 2015 pact and the broader U.N. climate framework that governs the annual talks, said Richard Goldberg, who worked as a top staffer on Trump’s White House National Energy Dominance Council and is now senior adviser to the think tank Foundation for Defense of Democracies. “You have to degrade it. You have to deter it. You have to potentially destroy it.”

Trump’s approach includes striking deals demanding that Japan, Europe and other trading partners buy more U.S. natural gas and oil, using diplomatic strong-arming to deter foreign leaders from cutting fossil fuel pollution, and making the United States inhospitable to clean energy investment.
