The graph compares the level of greenhouse gas emissions in two years of 2002 and 2030, and the level of carbon dioxide emissions such as waste combustion, transportation, consumer, industry, and other sectors throughout the world.
Overall, It is clear that in 2002 more than half (52%) of greenhouse gas emissions accounted for OECD, but estimated to substitute its position to developing country (48%) in 2030.
Although, in 2002, the highest proportion of greenhouse gas emissions contributed for OECD and developing countries ranked second by accounting 38%, the least proportion is for transition economies (10%). Industry is the highest carbon dioxide emissions which is more than 6 billion tons belonged in 2002 and will be soared dramatically to more 10 billion tons. While, consumer and transportation are responsible for carbon dioxide emissions, approximately less than 5 and 2 billion tons, respectively.
In contrast, in 2030 it is estimated developing countries’ greenhouse gas emissions will be rose gradually from 38% to 48% among two other contributors. Moreover, OECD contribution will decline slightly from 52% to 43%. During this period transition economies will remain almost steady with slight decrease from 10% to 9%. Also, it is forecasted that carbon dioxide emissions from industry will be doubled from 6 to 11 billion tons.
More than 9 billion tons will be emission from consumer in 2030 which is three-fold more than its level in 2002. This pattern is similar transportation amount of carbon emission. waste combustion and other sectors remain unchanged for 28 years.
