Big Oil backs carbon tax push

Reed Saxon / AP

A strange bedfellows coalition, including four of the world's biggest oil and natural gas producers, environmental groups and political leaders, are announcing a unified push urging Congress to enact a carbon tax to address climate change on Wednesday.

Why it matters: The support of major oil and natural gas companies — Exxon Mobil Corp., Royal Dutch Shell, Total and BP — will be needed to get Republicans to back a policy that remains politically toxic. The coalition represents the most diverse set of interests pushing Washington on climate policy in a decade.
