To keep the window open to limit global warming to 1.5 C, countries need to accelerate transformation towards a net-zero emissions future across all sectors at a far faster pace than recent trends, according to this report from World Resources Institute and ClimateWorks Foundation, with input from Climate Action Tracker.

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
