Burning hydrogen increases the production of nitrogen oxides, for example, which if not addressed can increase harms for people living near a plant. Renewable energy like wind and solar is a clear solution: generate more electricity from renewables, and you can use less gas, and minimize the range of harms that come with that gas.

Union of Concerned Scientists’ (UCS) research shows that top fossil fuel producers’ emissions are responsible for as much as half of global surface temperature increase. The best solution: Replace fossil fuels with renewable energy. A small number of big corporations are responsible for the climate crisis.

But while greenhouse gas emissions may be reduced, a delivery fulfilled by a diesel-burning truck may lead to increases in emissions of smog-forming nitrogen oxides and lung-damaging particulate matter.

The majority 6–3 decision sharply curtails the EPA’s authority to set standards based on a broad range of flexible options to cut carbon emissions from the power sector—options such as replacing polluting fossil fuels with cheap and widely available wind and solar power coupled with battery storage.

Gas plants and infrastructure emit nitrogen oxides (NOx) during combustion, which degrade local air quality. And, perhaps most important, adding more clean energy sources will dramatically reduce the impacts from developing, transporting, and burning fossil fuels. First, there’s air pollution.

Some fossil fuel industry proponents have pitched coupling carbon capture and storage (CCS) with the methane reforming process to limit the resulting carbon pollution. A plant cofiring with 30% hydrogen, for example, could generate around 17% more NO x than the plant being fueled with only gas.

California’s leadership on reducing truck pollution has been on full display the past few years, passing critical regulations requiring 90 percent reduction in smog-forming nitrogen oxide (NO X ) emissions from diesel trucks and requiring manufacturers sell an increasing share of electric trucks to move away from fossil fuels altogether.
