The California Dump Dirty Diesels Campaign
Since 1990, NRDC's advocacy victories have brought about a 56 percent reduction in diesel soot emissions in California. We have focused on this potent and toxic air pollutant because it is responsible for the majority of negative health impacts from air pollutants in California, including 70 percent of the cancer risk. While we have made great strides overall in protecting health and the environment in California, toxic hotspots such as ports, rail yards, and major freeways continue to present a serious risk for many of our communities. Employing legal advocacy -- and public campaigns such as the Clean Cargo Project -- NRDC is aggressively pursuing needed regulations for these hotspots.
The Many Dangers of Diesel Exhaust
Diesel engines emit a toxic brew of particulate matter (PM), smog-forming nitrogen oxides (NOx), and at least forty different toxic air contaminants. Diesel PM is a well known human carcinogen. Additionally, numerous studies have documented a range of adverse health impacts from long-term exposure to fine PM, including increased risk for cardiovascular disease (such as atherosclerosis and heart attack), birth defects, low birth weights, premature birth, more frequent emergency room visits for acute health events, and higher general mortality rates.
NRDC Victories Have Reduced Pollution While Saving Lives and Fuel
Almost 50 percent of smog-forming NOx emissions from diesels are expected to be reduced between now and 2020 due to rules and programs that NRDC fought for and won. Diesel soot emissions have already been cut in half since 1990. Since the California Air Resources Board's adoption in 2000 of the first "in-use diesel clean-up" rule for transit buses, NRDC has worked to ensure that 15 subsequent in-use diesel rules are as strong as possible. These rules resulted in fuel savings of an estimated five billion gallons of diesel and thousands of lives saved because of reduced pollution.
Many of these first-of-their-kind regulations are unfortunately under attack by various industry associations. NRDC has devoted significant legal resources towards defending these programs to ensure that their health benefits are not lost.

Hotspots: Responding to Emerging Pollution Threats
Strict standards for new diesel trucks and construction equipment, together with recently adopted "in-use" regulations, will significantly reduce diesel emissions in the coming decades. Unfortunately, under-regulated sources such as ships and trains will emerge as increasingly dangerous threats to health and the environment.
Toxic hotspots for diesel pollution may already be worsening at major commerce hubs such as ports and rail yards, and along freeways. These areas will experience significant increases in pollution with the growth of trucking and trade. For decades, the communities living in these areas have faced harmful levels of diesel pollution, and now even more people may become exposed to these toxic hotspots as the housing crunch forces new development into areas heavily impacted by diesel pollution.
NRDC is pushing hard to protect families in disproportionately impacted areas—along with their air, land, and water—by dumping dirty diesels in favor of cleaner, safer, and more efficient technologies. NRDC's Clean Cargo project targets the remaining diesel toxic hotspots for clean up through continued advocacy in California and sharing the tools that have worked well here with other regions experiencing growth in trade. We are employing legal tools to defend important existing regulations, while pressing for broader clean-up initiatives at ports and rail yards across the country. Finally, we are working with land use and transportation planners as well as health experts to direct new developments into areas that are less impacted by diesel pollution.
