EarthTalk: Obama's Climate Change Inititative

Dear EarthTalk: What is the gist of President Obama's new plan to tackle global warming and how does the green community feel about what the White House is proposing? -- Bill Kemp, Seattle, Wash.
In what's being billed as the greatest environmental initiative of his presidency, Barack Obama announced on June 25 that his administration is instituting stringent mandatory restrictions on greenhouse gas emissions by power plants, factories and other industrial sources.
These sources combined account for roughly 40 percent of all greenhouse gas emissions across the U.S. The goal is to reduce overall greenhouse gas emissions nationally by four percent below 1990 levels within the next seven years.
The new policy also directs the Department of Interior to approve enough renewable energy projects on public lands to power six million homes by 2020 and offers up $8 billion in loan guarantees for energy efficiency and advanced fossil fuel projects.
And while Obama helped shepherd in a doubling of gas mileage standards for automobiles, SUVs and pickups during his first term, he is now calling for much more stringent standards for heavy duty truck models introduced in 2018 and after.

Because the U.S. Supreme Court ruled in 2007 that the Environmental Protection Agency -- part of the executive branch under the White House -- can regulate carbon dioxide under the Clean Air Act just like it does soot, lead and other types of air pollution, Obama's new plan does not need Congressional approval, although Congress will certainly play a role in determining just how the emissions cuts are implemented.
"We limit the amount of toxic chemicals like mercury and arsenic and sulfur in our air and water," says Obama. "But power plants can still dump unlimited amounts of carbon pollution into our air for free. That's not right, that's not safe, and it needs to stop."
Most environmentalists are happy that Obama is finally committing to decisive action to reduce the nation's carbon footprint.
"This is the change Americans have been waiting for on climate," said the Sierra Club's Michael Brune. "President Obama is finally putting action behind his words." "It's clearly time to act,"
But other greens aren't so bullish on the new strategy. The Center for Biological Diversity, a leading non-profit committed to species protection, calls Obama's plan "modest," and warns that it falls short by failing to set a nationwide pollution cap for carbon dioxide.
