Carbon-heavy development in countries part of China's Belt and Road Initiative could render the Paris climate goals unreachable, according to a new analysis on the gargantuan global infrastructure project released on Monday.
The massive network of ports, railways, roads and industrial parks spanning Asia, Africa, the Middle East and Europe will see trillions invested in new infrastructure across 126 countries.
While the Chinese state is putting up a significant part of the cash, the project will also see other national and private-sector investment, and opponents warn of its devastating environmental impact.
An analysis of the possible carbon footprint of infrastructure development in Belt and Road (BRI) countries said there was a significant risk of the initiative alone producing enough greenhouse gas emissions to derail the Paris climate goals.
The 2015 accord enjoins nations to cap temperature rises to "well below" two degrees Celsius (3.6 Farenheit) above pre-industrial levels.
The Tsinghua Center for Finance and Development said that the 126 Belt and Road Initiative (BRI) countries excluding China currently account for 28 percent of manmade emissions.
It modelled the effects of different approaches to the development of megaports, pipelines, train lines and highways in 17 BRI countries.
It found that countries such as Russia, Iran, Saudi Arabia and Indonesia would need to lower carbon emissions 68 percent by 2050 compared to current trajectories in order to keep the world on course to 2C of warming.
"We have a business-as-usual scenario that says if you continue the way you are then even if every other country on the planet—which includes US, Europe, China and India—goes on a 2C pathway, this is still going to blow the carbon budget," says Simon Zadek, senior visiting fellow at the Tsinghua Center.
"The BRI growth dynamic is so large that if you get the carbon (emissions) wrong in a way it doesn't matter anymore what anyone else does."
