U.S. oil major Chevron Corp. has no plans to shrink its oil and gas business for wind and solar energy unlike some rivals, CFO Pierre Breber said on June 24, amid pressure from shareholders to lower carbon emissions.

Major oil and gas producers are facing pressure from investors to lower greenhouse gas emissions and adapt their business to a lower carbon future.

Chevron’s shareholders in May voted in favor of a non-binding resolution calling on the firm to cut emissions generated by the use of its products. That same day, a Dutch court ordered rival Royal Dutch Shell Plc to deepen its emissions cuts and Exxon Mobil Corp. lost three board seats to an activist fund advocating for a strategy that addresses climate change.

Chevron will invest some $3 billion into lowering emissions between now and 2028—a figure it expected to grow, Breber said at the Reuters Events Global Energy Transition conference.

Some $2 billion of that will go to address lowering carbon emissions in its own operations, while another $750 million will be allocated for renewable fuels such as renewable natural gas, he added.

Shell last week joined two Norwegian utility companies in a bid on the country’s first offshore wind auction. Earlier this month, BP Plc separately boosted its investment in renewable energy with the $220 million purchase of solar projects from 7X energy.
