Referring to the last post, we can conclude that most of the greenhouse gases are from energy use and the burning of fossil fuels. But, which which countries are contributing to these emissions and how much?
I think it is safe to say that greenhouse gases emissions are coming from most everywhere in the world, based on the map below.
What sectors of the economy contribute and how much?
The agriculture sector has GHG emissions from animals and from crop management. GHG are from animal wastes, energy use,livestodk,soil practices, crop burning, and livestock. The energy sector emitts GHG due to electricity generation and natural gas usage [3]. Industry/Manufacturing and Land use sectors contribute GHG by air condition, heating, refrigeration, and toxic pollutants, as well as production or processing of oil and gas. The Transportation sector has GHG emissions from cars that produce air pollutants and are not "green" vehicles. Also, especially in the United States, GHG emissions are extremely high for transportation because we travel everywhere. By reducing vechile use or miles traveled, we can cut down on GHG emissions. Waste management can increase waste diversion from landfills and recycle to limit the amount of GHG emissions. The water sector consumes a lot energy associated with water delivery, treatment, and use contributing to GHG emissions [3].
I think it is safe to say that greenhouse gases emissions are coming from most everywhere in the world, based on the map below.
The chart below is the per capita greenhouse gas emissions in 2005, including land-use change. Also in 2005 Qatar was the biggest contributor to GHG emissions with 55.5 tonnes of carbon dioxide [1]. This could be because Qatar has become one of middle east's wealthiest states "due to its enormous oil and natural gas revenues [2]."
Next in line for 2005 GHG emissions was United Arab Emirates (38.8 tonnes of CO2), then Kuwait (35.0 tonnes of CO2). To continue the list, starting with number four for highest emissions of CO2 is as follows: Luxembourg (27.5 tonnes), Australia (26.9 tonnes), United States (23.5 tonnes), Canada (22.6 tonnes), Trinidad/Tobago (19.6 tonnes), and number ten: Turkmenistan (18.9 tones).

The pie chart below shows some of the sectors and the percentage of energy consumption contributing to GHG emissions in the United States.
As seen by the chart, electric power and transportation are the biggest contributors to energy consumption. A similar graph again confirms that transportation and electricity uses the most energy in the United States, which was in 2006.
However, the Industrial field in the world is the largest consumer of energy. This could include processes like manufacturing, disposal, and heating/cooling.
Later posts will confirm the specific amount of energy use for the country of Kuwait, so we can gain a better sense of how much actual energy is used for a certain task, such as driving. It is clear that most everything uses some amount of energy, which contributes to a lot of GHG emissions.
