April 3 (Reuters) - Citigroup ( C/PN ), JPMorgan ( JPM )

and Royal Bank of Canada ( RY ) will disclose a new

climate metric under agreements between New York City

Comptroller Brad Lander and the three large North American

banks.

Lander, who oversees public retirement assets, said on

Wednesday that the three banks will disclose their ratio of

financing for low-carbon energy projects compared with their

financing for fossil fuel projects.

In return, retirement funds Lander helps run have withdrawn

shareholder resolutions at each bank calling for the

disclosures.

The new transparency will help investors "more effectively

measure how well they are or aren't living up to their

commitments," Lander said in a statement. "As leading public

investors, we expect that energy supply ratio disclosure will

become a new standard for the banking sector."

The bank's forthcoming reports should at minimum cover their

equity and debt underwriting, syndicated lending and project

finance, a representative for Lander said.

A JPMorgan ( JPM ) spokesperson said the bank found common ground

with Lander on disclosing a clean energy financing ratio, with

an understanding it would take some time and resources to

develop a decision-useful approach.

"We will engage with NYC and our shareholders to provide the

market more clarity and transparency about our activities and

what financing the transition truly looks like," the

spokesperson said.

RBC Vice President of Climate Jennifer Livingstone said its

talks with Lander had been constructive and said it planned to

boost lending to low-carbon energy projects.

"We plan to disclose a clean energy supply financing ratio

in our 2024 Climate Report as it aligns to our strategic

objectives," she said in an email. "Transparency and advanced

disclosures on climate performance are critical to showing the

progress we are making."

Citi declined to comment.
