U.S. President Joe Biden has forgone the traditional post-inauguration honeymoon period, issuing more than 40 executive orders within days of taking office. One of the first directives on his list confirmed his new administration’s intention to formally rejoin the Paris Agreement on climate change. This will occur on 19 February 2021 in a landmark move designed to reshape global climate policy for years to come. The U.S. re-adoption of the key goals set by the United Nations Framework Convention on Climate Change (UNFCCC) is widely seen as a curtain-raiser to Biden’s USD 2 trillion clean energy program and environmental leadership drive, which were promised during his election campaign and have since been outlined in an executive order. The 46th president has acted swiftly to reassure the international climate community of the U.S.’s allegiance by appointing a special envoy for climate and reaffirming his intention to position the environment as the centerpiece of U.S. foreign policy through a ‘whole of government’ approach.
