Countries committed under the Paris Agreement to a broad goal of limiting global temperature rise to under 2 degrees C (3.6 degrees F), ideally 1.5 degrees C (2.7 degrees F). The latest report from the Intergovernmental Panel on Climate Change (IPCC) makes it clear that half a degree of warming makes a huge difference, and 1.5 degrees C is the safer target.
So how and where do we start to get to 1.5, rather than 2 degrees or worse? The most recent climate science shows that our most likely, least expensive option is to peak global greenhouse gas (GHG) emissions by 2020 and dramatically reduce them from that point forward.
The Mission 2020 campaign defines six milestones –in energy, transport, land use, industry, infrastructure and finance – that give governments and industries a clear roadmap to put us on a path towards achieving 1.5 degrees C. In a working paperpublished today, WRI found progress in some areas, but we'll need faster action in order to achieve the 2020 turning point.
Here are 12 charts that measure progress on the milestones.
