Consideration of the impact of climate change has penetrated urban infrastructure planning worldwide, and the water sector is no exception. This paper provides an approach to incorporate a low-carbon consideration and climate externalities into an environmental economic analysis for an urban water treatment work planning with a case study from Ningbo, China. The discounted incremental costs are calculated with carbon footprint accounting. The analysis confirms that the inclusion of GHG emission costs as a component in the techno-economic criteria affects the priority ranking for the siting options, and may lead to an 'entirely different decision on the siting of the water supply facility. However, these criteria should be cross-examined with a sensitivity test during the decision making process, with the discounting rate and carbon pricing level being the main sensitivity factors. This study suggests that the benchmark discount rate for the water supply infrastructure average incremental economic cost accounting should be decreased from 6% to 4.5-4.0%. (C) 2015 Elsevier Ltd.
