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. This requires transformational changes from how power our homes and factories and build our cities to how feed our families and move around. So how is the world doing? Are countries, businesses, states and cities making the deep structural economic and societal shifts that are required? In this paper, World Resources Institute assesses progress toward six milestones set by Mission 2020 – in energy, transport, land use, industry, infrastructure and finance – that if met would put governments and industries on the path toward achieving the 1.5º C goal.
