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 Agreement. To achieve each milestone, the organizations identified two or more outcomes, and this working paper takes stock of progress made toward those outcomes.
