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 not...

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 ...

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...

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, mi...
