A new study from experts at 30 international institutions is proposing concrete plans on how to make the deep emission cuts across 15 of the biggest economies to keep the world below a 2C degree temperature rise and avoid much worse climate change impacts.

The deep decarbonization report from the Pathways to Deep Decarbonisation Project takes as its starting point the targets which governments have already agreed under UN climate change negotiations but which have not yet been achieved. “We do not subscribe to the view held by some that the 2C limit is impossible to achieve,” the report said, adding that the science about the 2C degree threshold was clear.

Jeffrey Sachs, director of Columbia University’s Earth Institute, and a leader of the project was quoted in a story about the report saying the detailed data on electricity supply, transport and shipping, and building codes in each country, was aimed at turning these targets into operational realities.

The study looks at the economies of America, Australia, Brazil, Britain, Canada, China, France, Germany, India, Indonesia, Japan, Mexico, Russia, South Africa, and South Korea, which between them account for 70% of global greenhouse gas emissions.
