Country-specific GHG Emission Trends
In 2004, Annex I countries constituted 20% of the
worldâ€™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.

A 2 Â°C rise in temperature has increasingly been
referred to as the â€˜Magic Numberâ€™ in several climate
change forums. The rationale being that if the
world is to restrict the increase in temperature
to 2-2.4 Â°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.
