Described by the United Nations as a legally binding international treaty on climate change, the Paris Agreement, adopted in late 2015, aims to "limit global warming to well below 2, preferably to 1.5 degrees Celsius, compared to pre-industrial levels."
"We are going to have to think about additional action on top of that," he said. "And that will require further tightening of NDCs in future years but also, maybe, some cross-cutting initiatives at COP26 on methane, on deforestation, on accelerating the drive towards electric vehicles, which can be agreed across all countries."When it came to getting results, Turner stressed the important role national governments could play.
One example of how governments are attempting to generate change is in the automotive industry. The U.K., for instance, wants to stop the sale of new diesel and petrol cars and vans by 2030 and require, from 2035, all new cars and vans to have zero tailpipe emissions. In a separate interview with CNBC's Steve Sedgwick over the weekend, former U.S. Energy Secretary Ernest Moniz touched upon these subjects.
