New Jersey governor signed the toughest U.S. global warming law

Governor Jon Corzine made New Jersey the first state to call for strict greenhouse gas reductions by 2050 in an effort to fight global warming and climate change. Corzine signed the Global Warming Response Act that mandates greenhouse gas emissions in New Jersey to be cut by 16 percent by 2020 and 80 percent by 2050.

The new law also sends a message to the Bush administration, who opposes mandatory emission cuts, preferring voluntary goals instead. But that, Corzine says, is not enough. "We want to send a message to Washington. Wake up, get with the program and start doing something about greenhouse gasses," the Democratic governor told reporters.

Other states have introduced their own measures since the federal government has yet to require mandatory emission regulations. California also passed a greenhouse gas law recently that mandates emission cuts. And while it has a long term goal of cutting emissions by 80 percent in 2050, it is merely a target, and not enforceable like that of the New Jersey law.
