City of Santa Ana Environmental Checklist Discussion Environmental Setting State Greenhouse Gas Emissions Worldwide, California is the 121h largest emitter of carbon dioxide (CO2) and is responsible for approximately 2% of the world's CO2 emissions (CEC 2006). Transportation is responsible for 41% of the state's GHG emissions, followed by the industrial sector (23 %), electricity generation (20 %), agriculture and forestry (8%), and other sources (8%) (CEC 2006). Emissions of CO2 and nitrous oxide (N20) are byproducts of fossil fuel combustion, among other sources. Methane (CH4), a highly potent GHG, results From off - gassing associated with agricultural practices and landfills, among other sources. Sinks of CO2 include uptake by vegetation and dissolution into the ocean. California GHG emissions in 2006 totaled approximately 479.8 million metric tons (MMT) in carbon dioxide equivalents (CO2e). Greenhouse gas emissions other than CO2 are commonly converted into carbon dioxide equivalents, which takes into account the differing global warming potential (GWP) of different gases. For example, the Intergovernmental Panel on Climate Change ([PCC) finds that N20 has a GWP of 310 and methane has a GWP of 21. Thus, emissions of 1 tort of N20 and 1 ton of CH4are represented as the emissions of 310 tons and 21 tons of CO2e, respectively. This method allows for the summation of different greenhouse gas emissions into a single total. Climate change could impact the natural environment in California in the following ways (among others): Rising sea levels along the California coastline, particularly in San Francisco and the San Joaquin Delta due to ocean expansion. • Extreme -heat conditions, such as heat waves and very high temperatures, which could last longer and become more frequent. • An increase its heat- related human deaths, infectious diseases, and a higher risk of respiratory problems caused by deteriorating air quality.
