Incorporating gas-powered generation as a sustainable investment into Asian taxonomies could have unintended consequences, finds a new report by the Institute for Energy Economics and Financial Analysis (IEEFA).
Doing so could lock Asia into a high-emitting future while also posing a credibility and greenwashing problem that Asian policymakers and ESG debt investors would be wise to avoid.

This is particularly important as Europe and the U.S. ramp up their climate ambition, with the U.S. Treasury releasing a guidance last month requesting multinational development banks rapidly align portfolios with the Paris Agreement, develop targets for green bonds, ‘green’ the partnerships with financial intermediaries, and align policy based operations with climate goals.
A taxonomy specifies the technical requirements of an asset or project that companies must satisfy to enable the labelling of the project as a green or sustainable investment, giving ESG investors reliable information on where to deploy capital to support the acceleration of a sustainable energy transition.
However, the report notes that controversial or ‘transitional’ economic activities such as gas-powered generation are likely to be recognised in Asian taxonomies as sustainable investments, with energy policy planners attempting to justify the merits of gas and LNG as a reasonable bridging fuel to greening the economy.
There are many Asian taxonomies in preparation that are designed to prioritise an ‘orderly transitional pathway’, including a regional taxonomy for Southeast Asia.
While most Asian taxonomies have yet to acknowledge the undue influence of the oil and gas industry, this will be controversial going forward as the region contemplates replacing coal-fired generation with gas-fired power.
“Gas is a fossil fuel and its high emissions—like coal’s—do not equate to it being a sustainable asset,” says report author Christina Ng.
“And after more than a decade’s effort, carbon capture is yet to be proven as economically and technically viable at scale, which creates a credibility issue for labelling gas power plants as sustainable investments.”
The report notes that financial institutions could also be entangled in greenwashing risk as many of them are lenders to gas-related power projects and are green/sustainable bond issuers themselves.
“Investors could also be proactive and voice their concerns now over the direction of taxonomy discussions.”
Ng notes the existence of a sustainable finance taxonomy does not prevent projects that the taxonomy excludes—such as gas or carbon abatement projects—from being financed through conventional sources of finance. They just would not be labelled sustainable investments or qualify for sustainable debt instruments.
“If Asian policymakers and regulators want market development to proceed smoothly and taxonomies to be influential, now is the time to appreciate that industry is only one voice in market creation,” says Ng.
