As Trump slashes and burns his way through environmental regulations, including the Paris Accord, he continues to bet that political polarization will work in his favor. Not only are his anti-scientific, anti-environmentalist positions firing up some within his base, but those positions are driving a deep wedge within organized labor. And unbeknownst to many environmental activists, they are being counted on to help drive that wedge even deeper.

Trump already has in his pocket most of the construction trades union leaders whose members are likely to benefit from infrastructure projects – whether fossil fuel pipelines or new airports or ...... paving over the Atlantic. His ballyhooed support of coal extraction has considerable support from miners and many utility workers as well.

But the real coup will come if Trump can tear apart alliances between the more progressive unions and the environmental community. Trump hopes to neutralize the larger Democratic-leaning unions, including those representing oil refinery workers and other industrial workers. That includes the United Steelworkers, a union that has supported environmental policies like the federal Clean Air Act and California’s Global Warming Solutions Act, and has a long history of fighting with the oil industry – not just over wages and benefits but also over health, safety and the environment.
