The pie graphs show greenhouse gas emissions worldwide in 2002 and the forecast for 2030. The column chart shows carbon dioxide emissions around the world.

The graphs give past and future data concerning worldwide

carbon

dioxide

emissions

. As can be seen in the two pie charts, developing

countries

are expected to account for a bigger share of

emissions

in 2030, 48%, compared to 38% in 2002.

In contrast

, OECD

countries

are projected to make up a lower proportion, 43%, 9% down over the same period.

Countries

with transition economies are estimated to take up the remaining 9% in 2030, 1 % less than in 2002. The bar chart reveals that

carbon

dioxide

emissions

will expand to varying degrees in different sectors by 2030. The industry will continue to be the major producer of

carbon

dioxide

, rising to more than 10

billion

tons in 2030. Next comes the consumer sector, which is projected to more than double its

emissions

from less than 4

billion

to 8

billion

or more tons. Transportation, the third largest producer, will see a huge growth to 6

billion

, triple the amount in 2002.

By comparison

, waste combustion and other sectors make up a much lower proportion, each producing an estimated 1

billion

carbon

dioxide

. To summarise, developing

countries

will overtake OECD

countries

to become the major

carbon

dioxide

emission producer by 2030.

While

industry is responsible for the highest amount of

carbon

dioxide

emissions

, consumer and transportation experience the greatest increases.
