Reps. David McKinley and Kurt Schrader said they’ve crafted what’s long been a unicorn in Washington: a climate bill that can appeal to both parties and prompt serious emissions cuts.

In fact, McKinley, a West Virginia Republican who fights vigorously for a future for coal, and Schrader, an Oregon Democrat who stresses the urgency of addressing climate change, argue their approach is the only one with a chance of garnering substantial bipartisan support. That buy-in from both parties, they said, is necessary to create durable climate policy that won’t be chipped away over time by partisan politics.
