Yet automakers are reluctant to support these cleaner technologies, claiming there is no consumer demand. We know they're wrong and have launched the Clean Car Pledge Campaign to prove it. The campaign will show automakers and policymakers that consumers want clean cars. Soon Motor vehicles produce a third of the pollutants that cause US smog and a quarter of the US emissions of the heat-trapping gases that cause global warming. With the number of motor vehicles expected to grow dramatically in the next few decades, these problems will only worsen.
Automobile emissions have enormous impacts.
Their smog-forming pollution darkens our skies and clogs our lungs. Experts predict that global warming will lead to increasingly severe weather, broader ranges for diseases and pests, and reduced biodiversity and crop productivity. The time for clean cars is now. When fueled with clean power, battery electrics offer the greatest environmental benefits of any vehicle on the road. Improvements in the technology will increase environmental benefits and allow vehicles to go farther before recharging.
