A major Senate climate change bill is written and ready to be debated before the Environment and Public Works committee, the chairwoman of the panel said Tuesday.

Sen. Barbara Boxer’s legislation would distribution of tens of billions of dollars of pollution allowances to power plants, manufacturing, and other industries. It will mirror cap and trade legislation passed by the House in late June with, she noted, “a few tweaks.”

The legislation has been sent to the Environmental Protection Agency for analysis, which should be completed by the end of the month.
