While national governments negotiated the Paris Agreement, its goal – to limit the increase in global temperature to under 2 degrees Celsius – can only be achieved if subnational state and local leaders, businesses, scientists, students, nonprofits, and others step up. The Summit, bringing together people from all walks of life, will showcase the surge of climate action around the world – and make the case that even more must be done.
The Summit will also help strengthen the push for greater emissions reduction targets at the United Nations Framework Convention on Climate Change’s 24th Conference of the Parties (COP 24) in December 2018. At COP 24, leaders will begin to set goals for the 5-year period that starts in 2020. A groundswell of climate action from the Summit will show that national leaders can, and must, further decarbonize the economy.
