The level of detail of the results, and their reliability, clearly varies from country to country, depending on the availability of data, the sophistication of analysis tools, and the amount of resources which could be applied to clarifying costs and potentials of abatement options. The ten country studies involved in the project achieved by no means the same level of detail in their analyses of GHG abatement. Some countries joined the project at a relatively late stage, while others had a long tradition of similar work and expertise which could be built on. The country teams also used different models, and had quite different amounts of data available. Thus a significant spread in the extent of the analysis is inevitable.
Work is likely to continue in all the countries, extending the breadth and depth of the analysis.
Part of this continuing work will make up Phase Three. The studies build on the Phase Two work and are being undertaken by the Department of Energy and the Southern Centre for Energy and Environment in Zimbabwe, and by the Ministry of Energy and Mines, Venezuela. The local teams are supported by the Energy Systems Group at Ris , Denmark, and Lawrence Berkeley Laboratory, USA, respectively. The UNEP Centre is also participating actively in both country studies and in the further development of the guidelines. The Phase Three studies are financed by UNEP and are scheduled for completion in mid-1994.
