Denmark emissions of greenhouse gases (CO2, CH4, N2O) 1990 and 2010 projections Denmark emissions of greenhouse gases (CO2, CH4, N2O) 1990 and 2010 projections
Emissions from human activities, and primarily fossil fuels, contribute to climate change, global warming and the greenhouse effect. This is primarily from industry, energy, transportation and related sectors. Please note that this collection of graphics has since been updated, please see http://www.grida.no or http://unfccc.int/ for the latest information and graphics.

Human influences on the atmosphere during the industrial era Human influences on the atmosphere during the industrial era
In many of the world’s largest cities (Beijing, Calcutta, Mexico City, Rio de Janeiro, etc.) WHO World Health Organization) air quality guidelines are not met. In 1996 global emissions of carbon dioxide were nearly four times the 1950 total.

Greenhouse gas (GHG) emissions by source, 2004 Greenhouse gas (GHG) emissions by source, 2004
Overall, agriculture (cropping and livestock) contributes 13.5 % of global greenhouse gas emissions mostly through emissions of methane and nitrous oxide (about 47% and 58% of total anthropogenic emissions of CH4 and N2O, respectively). The largest producer is power generation at 25.9% followed by industry with 19.4%.

The degradation of arctic sub-sea permafrost is already releasing methane from the massive, frozen, undersea carbon pool and more is expected with further warming.

Methane in Air Above Water Surface Methane in Air Above Water Surface
Mixing ratio of methane in the air above the water surface measured along a ship’s route in September 2005. The dotted line shows the Latitude-specific monthly average of 1.85 parts per million by volume established for the Barrow, Alaska, USA, monitoring station at 71° 19’ N, 156° 35’ W (http://www. cmdl.noaa.gov/ccgg/insitu.html); this is the normal level of methane in the atmosphere at this latitude.

Sustainable development mechanism projects by type Sustainable development mechanism projects by type
Of the 1003 projects falling under the framework of Clean Development Mechanism (CDM) which have been implemented in the region of Latin America and the Caribbean, the majority of the projects are related to renewable energy sources and reduction of methane (87% of the total). Only 1% of the CDM projects are related to transportation, 2% to forestation and reforestation, and 2% to fuel substitution. Consequently, there is a clear need for more ex...

Methane (CH4) and nitrous oxide (N2O) emissions in Latin America and the Caribbean Methane (CH4) and nitrous oxide (N2O) emissions in Latin America and the Caribbean
In addition to carbon dioxide (CO2), other greenhouse gasses that play an important role in the region are methane (CH4) and nitrous oxide (N2O). These gasses are produced primarily in the sectors of waste management, mining, industrial processes, and in the production and distribution of natural gas, petroleum and agricultural products. Among the region’s countries, Brazil is the highest emitter of both methane and nitrous oxide. Other countries...

Energy consumption by usage in a building Energy consumption by usage in a building
Buildings (residential and commercial) account for 10 to 15% of all greenhouse gas emissions, including almost 70% carbon dioxide and 25% methane.
