Sanders unveils climate change plan

WASHINGTON (AP) — Vermont Sen. Bernie Sanders is rolling out a plan to slow the effect of climate change, vowing to cut U.S. carbon emissions by 40 percent by 2030.
The Democratic presidential candidate said in a proposal released on Monday he would seek to impose a tax on carbon dioxide pollution, long a nonstarter with majority Republicans in Congress, and aim to slash carbon pollution in the U.S. by 80 percent by 2050 compared to levels in 1990. The proposal, he said, would put "people before the profits of polluters."
