Quizplus · Accepted Answer

During his campaign, Barack Obama proposed a "cap and trade" system in which the government would auction permits to emit carbon. This would create a market for companies to buy and sell emissions permits, ultimately reducing carbon emissions by imposing a cap on the overall amount of emissions allowed. The government would auction off the permits, providing revenue that could be used to invest in clean energy and other climate change mitigation efforts.
