Emissions from fossil fuel combustion account for a majority of anthropogenic CO2 emissions. In 2008, global emissions of CO2 from energy use totaled 30 gigatons.
Application of Life Cycle Assessment to US Water and Wastewater Treatment Facilities
This study documents the energy intensity and environmental impacts from operation of water and wastewater treatment systems through case-studies in US. Life-cycle energy and impact assessments were conducted for the Ann Arbor Water Treatment Plant (WTP) and Ann Arbor Wastewater Treatment Plant (WWTP) in Michigan. The framework for assessment was modified to assess the environmental burdens from Laguna WWTP in California and Ypsilanti Community Utility Authority (YCUA) WWTP in Michigan.
