Chinas$8 trillion plan to create a new Silk Road withsea and land links across Asiaisthe riskiest environmental projectin history, aglobal expert on major infrastructure projects has said.
The Belt and Road initiativeis already underway. Itaims to boost trade and economic growth across a vast area of the globe through the building of massive new transport infrastructure and energy projects.
But Professor WilliamLauranceof James CookUniversity in Australia has warned it could be the riskiest environmental venture ever undertaken.
China has enormous ambitions, but with that comes enormous responsibilities, he wrote in theNature Sustainabilityjournal.
If all goes to plan, theBelt and Road initiative will ultimately span at least 64 nations across Asia, Africa, Europe and the Pacific region.
By 2050 the project could involve 7,000 infrastructure projects seeing $8 trillion (5.9 trillion) in investment, Prof Laurance and his team of researchers wrote.
Last year, a report by the Fitch credit rating agency said $900bn(660bn) worth of projects were planned or already underway.
The initiative is made up of two main components: the Silk Road Economic Belt, and the 21st Century Maritime Silk Road.
The belt is to be an overland corridor linking China to the Middle East, central Asia and continuing on to Europe.Oil pipelines,bridges, tunnelsand rail and road links will be built to sustain it.
The road will bemade up of sea links between China, east Africa and countries around the Mediterranean.
TheWorldwide Fund for Nature (WWF)has warnedthat the planned corridors overlap with the range of 265 threatened species includingsaigaantelopes, tigers and giant pandas.
They have also identified that routes overlap with 1,739 designated important bird areas or key biodiversity areas as well as 46 biodiversity hotspots.
China claims its Belt and Road will be a blueprint for responsible development, but thats going to require it to fundamentally change the way it does business internationally, said Professor Laurance.Too many Chinese firms and financiers operating overseas are poorly controlled by their government in large part because they are so profitable.
He added: In the last two decades Ive seen countless examples of aggressive and even predatory exploitation by Chinese firms, especially in developing nations with weak environmental controls.
But the authors add that the project puts China in a position to change how their developers approach projects outside China which could potentially make them world leaders in sustainability.
China is doing a much better job of improving environmental safeguards inside China than internationally, said Professor Laurance.It has produced a mountain of green documents and promises about the Belt and Road, but a leopard doesnt just change its spots overnight.
China has a unique opportunity, but if its business as usual then the costs for the environment and economic risks for investors could be flat-out scary.
The report comes as climate scientists warn unfettered economic growth could spur rapid global warming.
Models may have to be recalibrated for projections of what a worst case climate change scenario is, as new studies take into account greater global economic growth than previously forecast.
The Centre for International Climate Research in Norway recently said the rise in carbon emissions in Europe over the past four years hascome as economic growth has sped up. In 2017, EU emissions rose by 1.8 per cent.
