The U.S. and China announced a landmark joint agreement Wednesday to cut back on greenhouse gas emissions.

“We have a special responsibility to lead the global effort when it comes to climate change,” stated Obama at the APEC summit on Nov. 12.

Together, the U.S. and China emit almost a third of the world’s greenhouse gasses. Under the terms of the proposal, the U.S. will emit at least 26% less carbon dioxide in 2025 than it did in 2005. China said it would boost use of renewable and nuclear energy to begin reducing emission levels.
