Barack Obama
Would implement an economy-wide cap-and-trade program to reduce greenhouse gas emissions to the level recommended by top scientists. Would make the United States a leader in the global effort to combat climate change by leading anew international global warming partnership. Would establish a National Low Carbon Fuel Standard (LCFS) to speed the introduction of low-carbon non-petroleum fuels. Would create a Technology Transfer program within the Department of Energy dedicated to exporting climate-friendly technologies to developing countries. Would offer incentives to maintain forests globally and manage them sustainably. Would develop domestic incentives that reward forest owners, farmers and ranchers when they plant trees, restore grasslands or undertake farming practices that capture carbon dioxide from the atmosphere.
 Watch Obama speak about the environment

Ron Paul
States the key to sound environmental policy is respect for private property rights. Believes the strict enforcement of property rights corrects environmental wrongs while increasing the cost of polluting. Individuals, businesses, localities, and states must be free to negotiate environmental standards. Voted against the drilling in the Arctic National Wildlife Refuge in 2001, but voted for new oil refineries in 2006. Opposes the Kyoto Protocol. Voted in 2003 against speeding up forest thinning projects. Read more about Paul's environmental policies
