“The US has a singular responsibility to lead: It is second in global climate pollution after China, but far and away responsible for the largest share of cumulative emissions. Since 1850, the US has released a fifth of all carbon emissions, far ahead of every other country, according to an analysis by the research group Carbon Brief.
But US political polarization remains one of the biggest obstacles to global action. The US has never come to an international conference with a comprehensive climate agenda backed by Congress, mostly because Republican lawmakers have refused to negotiate on a serious action plan. So Democrats have banked on passing Biden’s climate plans in the Build Back Better agenda with a simple Senate majority. Their bet on reconciliation has put a good portion of Biden’s climate agenda in the hands of West Virginia Sen. Joe Manchin, who is personally invested in the coal industry.
Biden brings a mixed bag of promises to Glasgow. The administration does not have a signed, final law from Congress that backs up his words with billions of dollars in funding. What he has are ambitious promises of slashing pollution in half by 2030, quadrupling international aid, and helping countries adapt to the impacts of climate change. Most of that will depend on Congress following through, and a successful regulatory agenda that survives Supreme Court scrutiny.”
