Banks and regulators around the world are putting growing pressure on companies.

In China, The Industrial and Commercial Bank of China - the largest bank in the country - revealed plans to include environmental risk as a criteria when screening for loans. The decision is linked to policy changes in the country to try and tackle air pollution and improve emissions standards.

The Securities and Exchange Commission in the US ordered global oil giant Exxon Mobil to let shareholders vote on a climate risk resolution. This decision overrules an attempt by Exxon to block a shareholder resolution  forcing the company to reveal how climate action could affect its profits.

And, at a meeting of leading bankers in London, Bank of England governor Mark Carney stated that green finance would be a priority for the next G20 meeting in China.
