78% of the total greenhouse gas emissions increase from 1970 to 2011 comes from fossil fuel combustion and industrial processes. The second-largest contributors to this increase are agriculture, deforestation, and other land-use changes.
Singapore contributes around 0.11% of global emissions. The average Singaporean generates a shocking 9000 kg of carbon emissions annually, which is twice of the world's average, and more than four times the target to maintain a sustainable footprint.
