Climate change in Washington The main Global greenhouse Gas released in Washington include carbon dioxide (CO), methane (CH4), nitrous oxide (N2O), and other gases that contribute to global warming. The different emission types are placed into three categories: energy, industrial processes and agriculture. Different greenhouse gases range in their individual impact on global warming. For instance, one pound of nitrous oxide is 296 times more potent than a pound of carbon dioxide in contributing to global warming. This means even small quantities of gases emitted into the environment, like nitrous oxide, can have significant impacts on global warming. For Washington state in particular, energy
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%)
