Emission inventory for greenhouse gases Rotterdam
Topic of the practice
The city of Rotterdam developed a CO2 footprint as part of the Rotterdam Climate Initiative (RCI). The footprint was developed independently from the regional AQ emission inventories for PM and NOx It covers a different area (the port and the city territory) tan the regional emission inventory that covers Rijnmond (Rotterdam, the port + 14 smaller cities and municipalities).
Good Practice Information
For a detailed description we refer to http://www.dcmr.nl/binaries/publicatie/2010/nulmeting-rotterdam-2007.pdf, a document in dutch.
This baseline study forms the numerical starting point for the Rotterdam Climate Initiative (RCI). RCI is a collaboration of the city of Rotterdam, DCMR, the regional EPA, the Port of Rotterdam Authority and Deltalinqs the organisation of logistical and industrial companies in Rotterdam.
The 1990 CO2 emissions form the basis for the RCI target: a reduction of 50% CO2 emission in 2025 compared to the level in 1995. The situation in 2005 provides a complete and recent picture of the emission in Rotterdam, prior to the start of RCI. The situation in 2025 provides a good estimate of the emission according to autonomous development (existing policy without RCI application), as well as insights into the achievable reduction in CO2 emissions.
The 1994 emission level of approximately 24 Mton means that in 2025 the emission may not exceed 12 Mton. This baseline study differentiates between 3 groups of sources responsible for emissions: industry and energy generation, transport and ‘built up areas’ including homes and offices. This provides insights into where the major sources of emission derive from and therefore where the greatest effect can be achieved. This has become the base for formulating the actions and regulations in the RCI programme. The measurements and deviation from targets will be presented in an annual monitor-report.
The costs for compiling this inventory are not known as it was part of a larger process of building up a climate coalition in Rotterdam.
Evidence of success
The Rotterdam footprint is a good example for a number of reasons:
- it is a good emission inventory as such for the year 2005 but it also includes a forecast (2025) and a backcast (1990) of emissions so that it can be used for policy formulation.
- it was used for policy formulation and for creating awareness, that is why sources that are numerically not very important are still included: every sector has to contribute somewhat: climate is a shared problem.
- there is a monitoring program associated to it so that policy impact and the RCI targets can be monitored. Both the footprint and the monitoring program are well documented.
- Footprints can be made using the so-called ‘area-approach’, whereby the CO2 emission levels are determined on the basis of what is emitted by Rotterdam and the ‘user-approach’, whereby the emissions levels are related to the actual use in Rotterdam. This footprint contains both (for the reference year 2005).
