Campus carbon neutrality 11, 1997 and put into practice on February 16, 2005. The protocol targets industrialized countries because they are the ones producing most of the greenhouse gases. Specific chemicals that it wants to reduce are carbon dioxide, methane, nitrous oxide, Sulfur hexafluoride, hydrofluorocarbons, and perfluorocarbons. Thirty-seven industrialized countries and parts of Europe have signed and are bound by the agreement. The United States is not one of them. The Kyoto Protocol allots a specific amount of greenhouse gas emissions that each country can produce, however, countries can also trade emissions with other countries, resulting in the cap and trade system. If
Greenhouse gas emissions in Kentucky tons of perfluorocarbons (PFCs) (4.8 MMTCE), and 0.003 million metric tons of nitrous oxide (0.2 MMTCE) The major source of carbon dioxide emissions was fossil fuel combustion (96%), the majority of which is utility coal. Minor emissions came from cement and lime production and forest/grassland conversion. Carbon dioxide sinks (i.e., an increase in forest carbon storage) offset about 26% of the total carbon dioxide emissions. Sources of methane emissions were coal mining (73%), domesticated animals (12%), landfills (10%), manure management (3%), and natural gas/oil extraction (2%). Nitrous oxide emissions were from fertilizer use. Sources of perfluorocarbons were HCFC-22 production (91%)
