The table provides an illustrtion on the energy production’s CO2 emissions from 5 countries: the USA, China, Russia, Japan and India with their positions in the world rank in the years of 1985, 1995 and 2005.
Overall, all countries with the exception of Japan increased the gas emissions in their production. The world changed in 1995, but after that remained the same.
More precisely, two countries, namely China and India, experienced a rapid increase in the CO2 emission throughout the whole period: with the growth by over two and three times respectively. The US and Russia increased the production of CO2, but in a more steady manner: from 5.8 Gt in 1985 to 6.9 Gt in 2005 for the US and from 1.5 Gt to 2 Gt for Russia in the same years. The numbers for Japan fluctuated starting from 1.2 Gt in 1985 with a slight rise for 0.1 Gt in 1995 and decrease back to the initial number in 2005.
Turning to ranking system, the leader of 1985 was the US, but fell to second place due to the rise of energy production in China. At the same time, Russia and Japan lost in rank both by one point and remained at the same level up to 2005. By contrast, India changed its positions from fifth 1985 to the third place in 1995 and on.
