GM is dedicated to improving vehicle fuel economy and being part of broader energy security and climate change solutions. During the last 30 years, we have doubled passenger car fleet fuel economy and increased light truck fleet fuel economy by 60 percent.

In the last few years, we have:

• Offered more models than any other automaker that achieve 30 miles per gallon or more on the highway;
• Sold more than two million vehicles that can run on E85 ethanol;
• Developed eight hybrid vehicles for the 2008 model year – including the world's first two–mode hybrid that improves both city and highway mileage;
• Developed plans for extended-range electric and fuel cell vehicles such as the Chevrolet Volt concept and Equinox.

There is no question that our products and manufacturing facilities have an impact on the environment. Not only do internal combustion engines produce emissions and greenhouse gases, but in the process of building millions of vehicles per year, our manufacturing facilities emit CO2 and greenhouse gases as well. GM is committed to reducing our impact on the environment.

Facilities
Innovative technologies have already helped us improve the environmental performance of our facilities. Greenhouse gas emissions are down, as are total carbon dioxide emissions. And recycling is up.

Cars and Trucks – Hydrogen is the Future
From the beginning, cars and trucks have been powered by the internal combustion engine, and while we are making the ICE better every year, improving old technology is not enough. Innovative technologies will provide the answers we need going forward.

Hydrogen Fuel Cells: Ultimately, we expect hydrogen fuel cells to replace the internal combustion engine altogether. Fuel cells, which produce electricity from hydrogen and oxygen, emit clean water and nothing else. Over the long term, the hydrogen fuel cell offers the best strategy for reducing our dependence on petroleum and eliminating CO2 emissions.

Hybrid Electric Vehicles: It will take approximately a decade until safe, affordable hydrogen fuel cells are widely available. In the meantime, GM will offer a range of hybrid cars and trucks and continue to improve the internal combustion engine. Beginning this year, we will introduce our first hybrid electric powertrains, which will eventually power over a dozen vehicle models, including pickup trucks, SUVs and sedans.

Better Internal Combustion Engines
We also are continually improving the internal combustion engine to provide better efficiency, fuel economy and performance. We have already begun rolling out a range of technologies, including the fuel-saving Displacement on Demand. In the short run, these technologies will help protect our natural resources, as we work toward longer-term solutions.
