According to this article, the G20 is making a commitment to “green finance”.

The conventional economic-development model viewed environmental protection as a “luxury good” that societies could afford only after they became rich. Such thinking explains why the dramatic growth in global income, 80-fold in real terms during the last century, has been accompanied by a decline, according to the United Nations Environment Programme, in natural capital in 127 of 140 countries…

But China is already taking concrete steps in the right direction. On August 30, President Xi Jinping presided over a decision by the Central Leading Group for Comprehensively Deepening Reforms to transform China’s financial system to facilitate green investment. The so-called “guidelines for establishing a green finance system” adopted at the meeting represent the world’s first attempt at an integrated policy package to promote an ambitious shift toward a green economy.

According to the guidelines, China will have to develop a wide range of new financial instruments, including green credit, green development funds, green bonds, green equity index products, green insurance, and carbon finance. It must also introduce a host of specific policies, regulations, and incentives, including innovative use of the central bank’s relending operations, interest subsidies, and guarantees. And it must establish a national-level Green Development Fund, much like the United Kingdom’s Green Investment Bank.
