Developing countries, such as India- main source of greenhouse gases
It might be very heart wrenching to know that the emission of global yearly carbon 
dioxide from fossils ad manufacturing cement have increased from 6.1 bn tonnes in 1992 to 8.5 billion tonnes by 2007. But more alarming signs are that recently the US Department of Energy's Carbon Dioxide Information Analysis Centre at Oak Ridge National Lab (ORNL), through their studies that presently developing countries like China and India have become the biggest source of emission of such gases.
Gregg Marland of ORNL's Environmental Sciences Division, informed, “The most recent estimates suggest that India passed Japan in 2002, China became the largest emitter in 2006, and India is poised to pass Russia to become the third largest emitter, probably this year. The US was the largest emitter of CO2 (carbon dioxide) in 1992, followed in order by China, Russia, Japan and India.”
According to the latest findings, the amount of annual emissions of greenhouse gases is increasing at a very fast pace and further the pattern has also altered significantly since the drafting of the United Nations Framework Convention on Climate Change in 1992.
Following this, the International community thought to take a productive step towards limiting the emission of greenhouse gases.
A press release issued by ORNL, informed that 38 developed countries previously agreed in the Kyoto Protocol, to reduce their emissions of greenhouse gases in order to reduce the adverse affect put by them on the earth’s climate.
The release further read, “At the time of drafting the United Nations Convention, those 38 countries were responsible for 62 per cent of carbon dioxide emissions attributable to all countries. By the time the Kyoto Protocol was drafted in 1997 that fraction was down to 57 per cent.”
The Kyoto Protocol came into force in 2005, and the recent emission estimates show that by then 38 countries “were the source of less than half of the national total of emissions, and this value as of 2007 was 47 per cent.”
Presently the developing countries including India are the main source of global emission of greenhouse gases. Excluding the U.S., around 181 countries have approved the Kyoto Protocol till now.
