California has postponed enforcing its strict new diesel-emission standards for four years.
With Honda's president saying the company had "no future" if it didn't make vehicles that emitted less carbon dioxide, the Japanese carmaker is now gearing up to join Toyota, GM and Nissan in the electric-car and plug-in hybird derby.
Some 115,000 people have signed up at Nissan's website to get more information about the all-electric Leaf compact sedan, which goes on sale in December. Those folks, and anyone else who registers at the site by the end of Tuesday, can sign up to be among the first to own one of the zero-emission vehicles.
What are car makers tooting their horns about? All the earth-friendlier engines at the Detroit auto show. Hyundai's plug-in Blue Will concept car and Nissan's all-electric Leaf are just a couple of the new models. Companies are keen to show they are serious about raising gas mileage and reducing emissions.
In a political victory for Barack Obama, the U.S. president emerged from the global climate summit in Copenhagen late Friday with a deal with China, India and other key countries to reduce earth-harming emissions. But environmentalists were disappointed the cuts were not binding while skeptics weren't disappointed there was a deal at all.

Most dramatic is a proposal that rich nations provide a $100 billion per year to help poorer nations cope with emission cuts.
