A number of Bank of Japan policymakers see the need for an in-depth analysis of the economic impact a newly introduced funding program will have on efforts to tackle climate change, a summary of opinions showed Wednesday.

According to the summary, which details views expressed at the July 15-16 policy meeting, one member said the BOJ's move to offer zero-interest funds to financial institutions making loans and investments to tackle climate change was "appropriate" because it takes into account market neutrality and policy flexibility.

"With the fund-provisioning measure to support efforts on climate change, the bank will make sustained and positive efforts that can contribute to stabilizing the macroeconomy in the long run," the member said.
