Nearly 200 countries signed a pact at the COP26 climate conference in Glasgow last year calling on banks and financial institutions across the world to mobilise more finance to help achieve global goals and to seek innovative ways to pay for climate adaptation.

But a review of 32 banks throughout east and Southeast Asia showed that none had made any clear commitments or adequate implementation plans to meet the goals of the Paris climate agreement, according to Asia Research & Engagement, a Singapore-based environment group.

The banks have been quick to launch green financial products but they have lagged when it comes to cleaning up their existing products and carrying out policies required to divert capital away from carbon-intensive industries, it said.

"This raises concerns of greenwashing: that banks are seeking a marketing benefit for sustainable finance deals while providing higher levels of finance to dirty industries," the report said.

Of the 32 banks in major economies including China, Japan, South Korea, Singapore and Indonesia, only nine had long-term net-zero commitments for the emissions they finance, while only 13 have policies prohibiting the financing of new coal-fired power.

The highest-ranked Asian bank was the DBS Group in Singapore, which has set a long-term net-zero target but has not yet made any clear short- or medium-term plans, and also had a number of gaps in its financing policies.

DBS did not respond immediately to a request for comment.

Five banks were given the lowest rating because they had "barely started" their journey towards climate readiness, including China's Bank of Ningbo, Ping An Bank and the Shanghai Pudong Development Bank.

None of three banks immediately responded to requests for comment.

ARE said banks needed to establish clear climate policies that were aligned with national goals in order to avoid future regulatory risks and ensure their clients' transition to cleaner and more competitive technologies.
