Sustainable practices across the entire global development spectrum are critical to achieving global climate change objectives. Corporate and national business and marketing strategies will have to factor these in their plans. According to U.S. Environment Protection Agency (USEPA), the top greenhouse gas emissions come from the following sectors and activities:
1. Electricity and Heat Production is estimated to produce 25 percent of 2010 global greenhouse gas emissions. The emissions occur from burning coal, natural gas, and oil for electricity and heat. It includes emissions from industrial electricity.
2. Industries in chemical, metallurgical, and mineral transformation processes not associated with energy consumption are responsible for 21 percent of global greenhouse gas emissions. This segment excludes energy consumption and emissions from waste management activities.
3. Agriculture, Forestry, and Other Land use are responsible for 24 percent of global greenhouse gas emissions. Agriculture includes the cultivation of crops and livestock, and deforestation is responsible for the bulk of emissions. The estimate does not include CO2 removed from the atmosphere by sequestering carbon in biomass, dead organic matter, and oils. These offset approximately 20 percent of emissions from this sector.
4. Transportation is responsible for 14 percent of 2010 GHG emissions. Ninety-five percent of the world’s transportation energy comes from petroleum-based fuels, large gasoline, and diesel.
5. Buildings which include onsite energy generation and burning fuels for heat in buildings or cooking in homes, produce six percent of GHGs
6. Other energy usages not directly associated with electricity or heat production, such as fuel extraction, refining, processing, and transportation, emit ten percent of GHG.
Sustainable practices must be implemented across the entire spectrum of business segments outlined above. The road to slowing climate change for the world will be hard. We are still in the early stages of the global climate change reversal transition.
