According to saying of a new Global Carbon Project report “To become carbon neutral, first reduce all possible emissions and impacts and then contribute to a measured reduction elsewhere to balance the rest”. The report that was published on 3rd December shows that global carbon dioxide (CO2) emissions will likely reach a record high of 35.6 billion tonnes in 2012, up 2.6 percent from 2011. Carbon dioxide and other greenhouse gases warm the planet by absorbing the sun’s energy and preventing heat from escaping back into space. This phenomenon is called as green House effect, which is a major reason for global warming and polar ice melting. The Global Carbon Project, is in a broad sense an annual report card on mankind’s CO2 pollution.
1 PgC/yr = 1 Pentagram Carbon per Year(1 Pentagram = 1 billion metric tonne)
The analysis is done by the Global Carbon Project at the University of East Anglia and the Tyndall Center for Climate Change Research in the U.K. Report shows that China, the U.S., the European Union (E.U.) and India were the biggest emitters of global warming gases in 2011., also says emissions grew 3.1% in 2011, placing the world on a near-certain path towards dangerous climate change, such as more heat waves, droughts and storms.
According to reports India’s emissions grew 7.5% last year versus 9.4% growth in 2010, while emissions in the United States and the European Union fell 1.8% and 2.8% respectively in 2011. So there is a little bit relief for India in emission growth trend but still more is required.
The biggest contributors to global emissions in 2011 were China (2.5 PgC, 28%), the United States (1.5 PgC, 16%), the European Union (EU27; 1.0 PgC, 11%), and India (0.6 PgC, 7%). But the picture is different when we look at contributions to global emissions growth in 2011, it was largest from China (0.226 PgC above 2010 levels, 9.9% growth) and India (0.043 PgC, 7.5%).
In another study Bangalore is rated among the top polluted megacities of world, from the data collected by NASA’s high-tech satellites. Tel-Aviv university was tracking data of 189 megacities of world by the help of high-tech aerosol monitoring satellite.
