To adjust the focus of this picture a little closer, just our passenger cars and light trucks contribute to a whopping 58 percent of total transportation emissions, placing our car-centric society in the fossil fuel spotlight. Petroleum has accounted for more than 90 percent of transportation energy in the last 50 years.

It’s not just the poor air quality, long lines, and excessive fossil fuel company representation ; nations are still too far apart in their positions on a fossil fuel phaseout, the top priority for this COP. Yet global fossil fuel production and use continue to expand. Particulate matter (PM2.5)

And fossil fuel power plants may not stick to their retirement schedules for a variety of reasons. In 2021 alone, the plants slated for retirement emitted more than 28,000 tonnes of nitrogen oxides (NO x ), 32,000 tonnes of sulfur dioxide (SO 2 ), and 51 million tonnes of carbon dioxide (CO 2 ), according to EIA data.

And we’re still trying to recover from a pandemic that has made even more clear the disproportionate impacts of air pollution on overburdened communities, making them even more vulnerable to the negative impacts of COVID 19. Similarly, communities now tied to fossil fuels need support in moving beyond that dependence.

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.

We need more electricity to transition our homes and cars off fossil fuels, but we can’t afford to let that electricity come from more gas power plants. Because unlike moving sources of air pollution like cars, gas plants are completely stationary. Why is this inequitable and disproportionate siting a problem?

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.
