Nations Agree to Five-Year Reviews of Climate Change Commitments

By - JUL. 22, 2015

The Paris climate talks continue to gather momentum. At the recent ministerial gathering of 46 nations in Paris, countries agreed that there will be a five-year review of any climate change commitments that emerge this year. Chief French climate negotiator, Laurence Tubiana, called the discussion a "breakthrough" that “was not obvious to get."

This was one of the crucial milestones for the Paris climate talks being a success that Mike Bloomberg, the Secretary-General’s Special Envoy for Cities and Climate Change, had outline in his recent WSJ op-ed: “Success in Paris requires nations to agree that commitments should be revised every five years as technology advances. This will send an important signal to the private sector: Government policies will increasingly prioritize low-carbon development, which will spur greater investment in the technologies that will drive it.”

For nations to reach an agreement on a five-year review schedule before COP21 is another sign that the global community is serious about building momentum for a successful conference in Paris this December – and it happened the same week that Pope Francis signaled his commitment to and understanding of the role of cities in making climate progress, another sign of the momentum that is building on climate change.

There are so many facets to climate change that make it difficult to address, but you don’t give up just because it’s difficult. You work harder.
