Big oil privately acknowledged efforts to downplay climate crisis, joint committee investigation finds

Internal documents revealed by committee show companies lobbied against climate laws they publicly claimed to support

Big oil has privately acknowledged its efforts to downplay the dangers of burning fossil fuels, US Democrats have found.

Major fossil-fuel firms have also pledged support for international climate efforts, but internally admit these efforts are incompatible with their own climate plans. And they have lobbied against climate laws and regulations they have publicly claimed to support, documents newly revealed by the committee show.
