The world is already experiencing severe impacts of climate change, from extreme heat waves, sea level rise to species die-offs and crop failures. Must act quickly to stabilize global warming below 1.5° C (2.7° F) to avoid much greater threats, as the IPCC report released last October made crystal clear.

In 2017 several leading climate analysis organizations came together as part of the Mission 2020 campaign to define six milestones—in energy, transport, land use, industry, infrastructure, and finance—that would need to be met by 2020 to bend the curve in global greenhouse gas emissions and put the world on a pathway consistent with the Paris Ag

This paper discusses the development of the accounting guidance under the Paris Agreement.

Much has changed since countries first developed their NDCs. All Parties have the opportunity to communicate new or updated NDCs by 2020, informed by the outcomes of a facilitative dialogue in 2018, and incorporating advances in renewable energy, technology and policy developments in key sectors.

This paper assesses each of the world’s countries in terms of whether their greenhouse gas (GHG) emissions have peaked, when they have peaked, and whether they have a commitment that implies an emissions peak in the future.

When it comes to climate action, effective measurement, reporting and verification (MRV) of emissions and emissions reductions is critical to help countries understand GHG sources and trends, design mitigation strategies, enhance credibility and take other policy actions.
