“I would almost want to say, ‘let’s not mess it up. Let’s keep it rolling,’” he added in remarks to the Natural Gas Roundtable, where he responded to a question on climate policy.
But many climate advocates say that ultimately, a transition to very low and zero-carbon fuels will be needed to achieve the very steep emissions cuts necessary to avoid the most dangerous climatic changes.
Environmentalists back various proposals to impose a price on carbon emissions, such as cap and trade or a carbon tax.
Those proposals lack traction in Congress.
But the Environmental Protection Agency is weighing carbon regulations that will put even more pressure on coal-fired generation, which is increasingly squeezed by natural gas and rules to curb other pollutants.
