When Zabel and Williams released a video on the Internet expressing their concerns over the Obama administration’s plans to use a cap and trade program to fight climate change, they were told to keep it to themselves.

Laurie Williams and husband Alan Zabel worked as lawyers for the Environmental Protection Agency, EPA, in its San Francisco office for more than 20 years, and they know more about climate change than most politicians. But when the couple released a video on the Internet expressing their concerns over the Obama administration’s plans to use cap-and-trade legislation to fight climate change, they were told to keep it to themselves.

Williams and Zabel oppose cap and trade — a controversial government allowance program in which companies are issued emissions limits, or caps, which they can then trade — as a means to fight climate change.

“Cap-and-trade with offsets provides a false sense of progress and puts money in the pockets of investors,” Zabel said in the video. “We think that these restrictions might not be constitutional,” he said.
