Taking public transport by bus in the Chinese Metropolis Hefei as an example, the report analyses the practicability of standardised baselines as possible instruments for climate protection funding. The development of standardised baselines for the transport sector has been pushed since the nineties in order to better assess emission reductions of CDM projects. Further aims of standardising are a clinical comparison and a precise forecasting. For all projects of a defined sector, class, size or a given geographical origin it is possible to develop standardised baselines in the sense of reference value for emissions. The report was produced by Urda Eichhorst, Wolfgang Sterk, Susanne Böhler and Hanna Wang-Helmreich in the context of the initiative "Partnership on Sustainable Low Carbon Transport" (SLoCaT), commissioned by the Asian Development Bank. It complements the study "Applicability of Post 2012 Climate Instruments to the Transport Sector (SITS)", that analyses the impacts of climate protection funding mechanisms like the Clean Development Mechanism (CDM) in the transport sector of metropolises in emerging nations and gives recommendations for the further development of financing mechanisms.
