Although European banks have been tightening their lending criteria for fossils fuels as part of pledges to cut financed carbon emissions to zero by 2050, environmental groups and some activists investors have been urging them to go faster.
The new commitments, coming days ahead of BNP's annual shareholder meeting, also included a complete phasing out of all financing to non-diversified oil companies.
"BNP Paribas no longer provides dedicated financing for the development of new oil and gas fields, regardless of the financing terms," the bank said in a statement.
BNP Paribas had already announced plans in January to cut oil exploration financing by 80% by 2030, and on Thursday it confirmed it was on track with its climate change targets for the power generation, oil and gas and automotive sectors.
"Its new commitments are welcome and suggest that banks' financing appetite for new oil and gas is rapidly drying up," responsible investment group ShareAction said in a statement, though it added the bank still had a way to go.
A group of three climate-minded organisations - Oxfam, Friends of the Earth and Notre Affaire à Tous - which this year sued the bank over its fossil-fuel financing, said the move was a "small step", but added the banks climate policy was still not strict enough.
Indirect funding of gas projects via loans to involved companies, as well as the bank's handling of corporate bonds, were loopholes BNP still needed to close, ShareAction and the three groups involved in the legal case said.
Banks have been announcing plans to shift towards lower-carbon sectors and away from fossil fuels, although with many of their goals being targeted at 2030, it can be hard to assess progress.
BNP's French rival, Societe Generale (SOGN.PA), last year said it wanted to reduce its financial exposure to the oil and gas production sectors by 20% by 2025 compared with 2019.
Credit Agricole (CAGR.PA) pledged it would stop financing oil extraction projects by 2025.
BNP also said it had set new portfolio alignment targets for 2030 for the emissions-heavy steel, aluminium and cement sectors, saying it was looking to cut the "emissions intensity" of its investments by 10 to 25% from last year.
