While the pie charts provide greenhouse gas emissions worldwide between 2002 and 2030, the column chart illustrates carbon dioxide emissions in five different group included industry, consumer, transportation, waste combustion and other sectors.
Overall, while the data of greenhouse gas emissions in OECD and transition economies experienced a downward trend between 2002 and 2030, the proportion of emissions in developing countries recorded an upward tendency over the period. In addition, the carbon dioxide emissions by industry was the largest sector in 2002 and also in 2030. Meanwhile, the figure of waste combustion was the lowest over time.
In 2002, the greenhouse gas emissions in OECD accounted for more than a half of total, after which this figure is predicted to decrease significantly to 43% in 2030. In contrast, the amount of emissions in developing countries, which is forecasted to rose dramatically from 38% to 48% over the period of 28 years. In the meantime, the data of transition economies recorded 10% in 2002, followed by this figure will contract minimally to 9% in 2030.
In terms of the carbon dioxide emissions, industry started at 6 billion tons in 2002 and then is predicted to increase sharply to 10 billion tons in 2030. Followed by the consumer and transportation emissions rose significantly from 4 to 8 and from 2 to 6, respectively. Conversely, the data of waste combustion and other sectors remained around 1 billion ton over the period of 28 years.
