The Industrial and Commercial Bank of China, which is also called ICBC, has listed a $1.58 billion equivalent green bond on the London Stock Exchange, which is being used to finance environmentally sustainable assets.

The listing is the largest-ever for a green bond on the London Stock Exchange, which is also known as the LSE, and represents the first Chinese issuance on the exchange’s International Securities Market.

A green bond is a type of loan that companies, governments, and banks use to finance climate and environment projects.

“These bonds are priced extremely tightly, financing assets around the world, from China to Pakistan, to windfarms in Scotland, so it shows the reach of ICBC operations,” said Nikhil Rathi, chief executive of the LSE.

The new ICBC London green bonds are backed by a range of low-carbon transport assets, as well as those in wind, solar, and marine renewables, including three railway lines in China, multiple onshore wind and solar farms in China and Pakistan, and the 588-megawatt Beatrice offshore wind farm under construction in Scotland.

Sean Kidney, chief executive of the Climate Bonds Initiative, said the move signaled ICBC’s intent to become the leading green credit bank in the world. He said it also indicated China’s commitment to reducing the environmental impact of the Belt and Road Initiative, which is a major infrastructure and economic development plan involving more than 60 nations.

“We have an incredible challenge, globally, in addressing climate change and the environmental impact of pollution,” Kidney said. “President Xi Jinping said the Belt and Road project must go green, it’s critical for the world and it’s critical for China and it’s critical for those countries that learn from the Chinese example, to leapfrog to green.”

The dual-currency green bond includes a three-year floating rate dollar tranche that raised $500 million, a five-year floating rate dollar tranche that raised $500 million, and a three-year floating rate euro tranche that raised 500 million euros ($586 million).

Han Ruixiang, general manager of ICBC London Branch, said the bank will use the proceeds to finance green assets under the bank’s Green Bond Framework, including those in renewable energy, energy efficiency, low-carbon transportation, sustainable water, and wastewater management.

“These assets are located within the countries covered by the Belt and Road Initiative and include a UK offshore wind farm,” Han said.

John Glen, economic secretary to the treasury and city minister, said the strengthening of ties between the UK’s financial services industry and Chinese banks and investors is crucial in light of Britain’s pending exit from the European Union.

“As the UK leaves the European Union, it is really very important that we look to deepen these global financial partnerships,” Glen said. “The treasury is committed to strengthening the financial services industry relations with China.”

Global green bond issuance reached $155.5 billion in 2017, an increase of more than 78 percent from 2016, according to a report from London-based law firm Linklaters. China is one of the leaders in green bond issuances, making $36.4 billion available last year.
