Country-specific GHG Emission Trends

In 2004, Annex I countries constituted 20% of the world’s population, accounting for 46% of global GHG emissions, while non-Annex I countries constituted 80% of the world population but contributed to only 54% of the emissions. Moreover, the per capita emissions in developed countries are expected to remain substantially higher than those in the developing countries.

In the following figure, we can see per capita emissions of some countries.

The Magic Number of Global Warming... Click to know

A 2 °C rise in temperature has increasingly been referred to as the ‘Magic Number’ in several climate change forums. The rationale being that if the world is to restrict the increase in temperature to 2-2.4 °C (the point after which scientists say the planet would suffer irreversible damage; and the point upto which it would still be possible to adapt to its impacts with realistic efforts and affordable costs), then emissions need to be reduced by 50% by 2050. This is not all; IPCC also states that to achieve this goal, global emissions need to peak by 2015, and decline thereafter.

We will now understand the various mitigation options available to us.
