Session 44: Footprinting and low carbon urban infrastructure development
The concept of 'green growth' has been connected to the 'green economy for sustainable development and poverty reduction', which is the first theme of the Rio+20 United Nations Conference on Sustainable Development (UNCSD). Rapid growth requires intensive urban infrastructure development, but due to the constraints of local government capabilities, the funding of urban infrastructure has become a critical issue. Against this background, this session explored and examined a new funding mechanism with the engagement of many stakeholders including public-private partnerships. Several cities already have invested in initiatives for green cities.
This session highlighted a two-year project, used as guidance on how cities in selected countries can play a key role in the green growth agenda by stimulating growth through smart investment in urban infrastructure, i.e., by building a physical infrastructure, by financial and tax incentives, energy supply, and heightening society's awareness of a sustainable lifestyle. This two-year project funded by APN ranges from institutional analysis, life cycle assessment, and risk analysis to integrated assessment with the study cases of Jakarta, Shanghai and Yokohama.
Furthermore, this session addressed the quantification of urban carbon footprints and their contribution to global, regional and national GHGs. Given the slow progress of international climate policy negotiations, cities and their citizens are playing a pivotal role in the mitigation of climate change. However, approaches to carbon footprinting are facing some methodological and empirical problems: Data availability for both footprinting methods; questions of boundaries (legal boundaries in the case of cities, individual/household boundaries in the case of personal carbon footprints); 'grey' energy in cities, including urban infrastructure related emissions; and, problems of communication and dissemination beyond the level of technical experts. Can public communication of carbon footprints help to put forward the idea of environmental justice, and vice versa, can urban mitigation policies help to reduce social inequalities, thus contributing to an improved social 'climate' of cities?
