In order to enable environmental authorities in Chinese cities to generate a regular emissions inventory of the transport sector, GIZ China published the guide “Monitoring Greenhouse Gas (GHG) Emissions of Transport Activities in Chinese Cities – A Step-by-Step Guide to Data Collection”.
The report was developed as an output for the TRANSfer project, which is implemented by GIZ and financed by the International Climate Initiative of the German Ministry for the Environment, Nature Conversation, Building and Nuclear Safety (BMUB).
The guide provides a detailed approach for setting-up an emission monitoring system for urban passenger transport. Sensitive to both, the local traffic situations and data availability, the guide outlines three different approaches to calculate transport activities:
- The basic approach: Initial start on GHG monitoring. Calculations are mainly based on non-local default values but already allow a reasonable understanding of the sector;
- The advanced approach: Calculations are done with locally specific parameters resulting in reasonable accuracy;
- The developed approach: High Requirements for data availability provide highly accurate monitoring results.
The guide refers to the calculation tool China Road Transport Emission model which was launched in 2014 and is based on the European Handbook for Emission Factors (HBEFA).
The guide and the model are currently used by the China Sustainable Urban Transport Research Centre (CUSTReC) to calculate emissions in the cities of Chengdu, Suzhou and Harbin. It is based on practical experiences and CUSTReC and GIZ organised a trainings on emission quantification and monitoring in urban transport for the three cities. CUSTReC develops the emission monitoring system for the Large City Congestion and Carbon Reduction project of the Global Environmental Facility (GEF), which is managed by the World Bank and the Chinese Ministry of Transport.
For more technical details on modeling GHG emissions, and the approach of HBEFA adoption in China, a Technical Paper was developed. A short leaflet summarises the features of the CRTEM/HBEFA-China tool.
