Basically, carbon sinks are holding tanks for carbon or carbon compounds, like carbon dioxide (CO2). One of the largest reservoirs of carbon is the Earthâs hard rock crust. Over the eons sedimentary rocks were formed that contain loads of carbon compounds, including the hydrocarbons that we now use as fossil fuels.
China and the United States, the world's two largest economies, are responsible for emitting nearly half the planet's carbon dioxide emissions. China overtook the United States in 2006 as the world's biggest CO2 polluter due to its hardening coal addiction. Per capita, however, America's carbon footprint is far bigger.
