China National Offshore Oil Corp. said it will increase spending on clean energy so that its carbon emissions peak by 2028, while also bringing forward its net-zero deadline to 2050, according to the company’s climate action plan released Wednesday. The offshore oil and gas giant’s spending on renewable energy will account for 10%-15% of its total over 2026-2030, from a range of 5%-10% announced last year for the period through 2025. The emissions counted will only be the company’s own, and won’t include those generated by the customers of its fossil fuels.
