Jay Inslee proposed applying U.S. anti-corruption laws to climate change deniers overseas as part of a foreign policy shift away from what the Washington governor called the “Axis of Oil.”

The proposal, announced in a 50-page campaign position paper released Wednesday, lays out Inslee’s vision for mobilizing the entire world to shrink planet-warming emissions. The detailed plan could set a tone that Inslee’s rivals for the 2020 Democratic presidential nomination will mimic as the contenders compete in an arm’s race over climate policy.

Inslee’s proposal came a day after former Vice President Joe Biden and Sen. Elizabeth Warren (D-Mass.), two top-tier Democratic candidates in the 2020 election, unveiled their own climate plans with varying degrees of ambition. But it’s Inslee who looked poised to rattle the climate debate for the second time since the governor’s $9 trillion, Green New Deal-style proposal for a domestic climate jobs plan added new seriousness to a presidential campaign initially written off as quixotic.

Citing the far-right German party AfD’s recent targeting of Swedish teenager and climate activist Greta Thunberg, Inslee proposes using anti-corruption laws to “impose consequences for undermining international cooperation, including on climate and much more.” Inslee warned that “nations deeply invested in exploiting fossil fuel reserves are openly flouting consensus on climate change or targeting climate activists domestically,” and said the White House could use the Global Magnitsky Act, which gives the president the power to institute a travel ban or asset freeze on human rights violators in any country.

“We’re standing up against the most powerful economic interests in world history, namely fossil fuel industry and governments who are handmaidens to them,” Inslee told HuffPost.

In the plan, Inslee declared the “United States will not only cease to cooperate with these countries to impede efforts to confront global climate change,” but will threaten to “utilize the Global Magnitsky Act to hold to account individuals and entities responsible for human rights violations and corrupt activities that contribute to targeting civil society advocates, including climate activists.”

“It’s an extension of existing authority against a known threat,” Inslee said. “That’s the fossil fuel industry in league with governments to suppress voices around the country.”
