The pie graphs illustrate greenhouse gas emissions and forecasts from 2002 to 2030, while the column chart shows global carbon dioxide emissions.
Overall, in 2002, emissions from developing countries accounted for around half, whereas by 2030, emissions from the OECD nations were approximately half. Transition economies had the lowest emissions in both 2002 and 2030. In 2002, waste combustion emissions were the lowest among sectors, while industrial emissions were the highest. This pattern remained the same in 2030, with waste combustion still being the lowest and industry maintaining its status as the sector with the highest emissions.
In 2002, developing countries made up about half of the emissions pie chart, with 38%, while the OECD countries accounted for around 52%. By 2030, transition economies showed a 1% change compared to 2002. Emissions from developing countries dropped to 48%, while the OECD’s share decreased to 43%.
Worldwide carbon emissions by sector in 2002 showed that the ‘other’ sector and waste combustion had the lowest emissions, each contributing around 2 billion tons. In contrast, industrial emissions were the highest, at around 6 billion tons. The consumer sector produced 4 billion tons, and transportation accounted for about 3 billion tons. By 2030, industrial emissions remained the highest at 6 billion tons, while waste combustion continued to be the lowest at 2 billion tons.
