Over the last two decades much scientific effort has been expended on the radiative gaseous emissions in the atmosphere.
Although there are no regulatory requirements for managing gaseous emissions at present, the long term
indications are, that impact relater to air pollution must embrace the broad diversity and challenges associated with
urban wastewater cycle management. This study has been considered as a precursor to development of a comprehensive
impact assessment of gaseous emission from urban wastewater infrastructure and treatment facilities. It has
been carried out in consideration of the future climate change scientific projections, including socio-economic and
environmental impacts. Major progress could be gained from systemic approaches in relation to factors influencing
emission and the collected data demonstrates correlation between wastewater quality, treatment and energy used
with the level of emission. An early attempt was made to attribute environmental impact and costs on per capita
basis, as the weight of responsibility to take action is shifting to the community and individuals. The presented
framework and methodology offers reliable evaluation of gaseous emissions is an integrated context comprising
technology, environment, social and economic factors.
