The objective of this paper is to assess the impact of proposed Canadian climate change mitigation policies (discounting and carbon pricing) on cost, energy use, and greenhouse gas (GHG) emissions in the single-objective design/expansion optimization of the Amherstview water distribution system in Amherstview, Ontario, Canada. The single-objective optimization problem is solved with the elitist genetic algorithm (EGA). The optimization approach is used in a parametric analysis to examine the impact of discounting and carbon pricing on GHG reductions for cement-mortar ductile iron and polyvinyl chloride pipe materials. Preliminary results indicate that the discount rate and carbon prices investigated had no significant influence on energy use and GHG mass in the Amherstview system and did not meet the emission-reduction targets set by the Canadian government. This result was attributed to a number of factors, including adequately installed hydraulic capacity in the Amherstview system, the use of a time-declining GHG emission intensity factor, and the scope of the expansion problem.

This paper focuses on the status of policy studies on Global Climate Change and how renewable and high-efficiency generation technology can be part of the solution. It considers critical technologies and solutions toward realizing the targets set in the Kyoto treaty. Discussed is energy effi ciency in power generation, environmental benefits of high-effi ciency gas turbines in competitive energy markets which display less NOx and CO[sub 2] emissions per unit of power produced while providing power generators with the most competitive electricity, and experience in India in mitigating climate change with renewable energy as seen by the UN and an advisor to the Indian government in nonconventional energy sources. Also discussed is stabilization of greenhouse gas concentrations in the atmosphere that will present dangerous anthropogenic interference with the climate system as called for under the United Nations Framework Convention on Climate Change.
