At the UN this week envoys from more than 130 nations, including 60 world leaders, will convene to sign the Paris Climate Change Agreement. This historic deal, achieved during global climate talks last December, was bolstered by contributions from hundreds of city mayors and corporate CEOs who made their own climate pledges during the negotiations.
Now robust implementation of these pledges from cities, states, companies, and investors worldwide will be crucial to delivering on the agreement’s promise. But what do these commitments add to national plans? And how do they factor into the global climate agenda?
According to new Yale research, the potential impact of these commitments is crucial. In a new analysis published in Nature
, a research team highlights the need to move from a discordant system of climate commitments to a more transparent, coordinated, and comprehensive framework.
Using data from a UN registry known as NAZCA (Non-State Actor Zone for Climate Action)
, the Yale team analyzed more than 11,300 climate commitments from cities, regions, private companies, and financial institutions throughout the world. Launched in 2014 by the UN Framework Convention on Climate Change, NAZCA is the world’s most comprehensive climate action registry.
The new analysis, led by Angel Hsu
, an Assistant Professor at Yale-NUS College and the Yale School of Forestry & Environmental Studies (F&ES), provides a detailed picture of this sub-national and non-state climate action landscape.
