The main purpose of the study is to identify and quantify anthropogenic sources of atmospheric emissions of greenhouse gases in Tanzania. In particular the study aims at:

• increasing the quantity and quality of base-line data available in order to further scientific understanding of the relationship of GHG emissions to climate change;
• enhancing the ability of various institutions in Tanzania to monitor, and report national inventories of GHG sources and sinks;
• the promotion of exchange of information related to climate change and national policy options and technology choices that could lead to eventual reduction of GHG emissions world wide;
• the identification of national policy and technological options that could reduce the national level of emissions; and
• the promotion of institutional links within the country and between Tanzanian and international institutions and agencies.

This study is a collaborative effort of various institutions including:- the Ministry of Tourism, Natural Resources and Environment (MTNRE); the National Environment Management Council (NEMC); the Directorate of Meteorology (D0M); the Ministry of Water, Energy and Minerals (MWEM); the University of Dar es Salaam (UDSM); and the Centre for Energy, Environment, Science and Technology (CEEST); with the Department of Environment (DoE) of MTNRE being the lead agency. Other researchers were coopted for short durations from the Ardhi Institute, the Water Resources Institute, the Sokoine University of Agriculture, the Ministry of Agriculture (MoA), the Ministry of Lands, Housing and Urban Development, and the Department of Forestry. The institutional links between CEEST and SCEE have been an important feature of this study. A National Steering Committee oversaw and gave guidance on the implementation of the study. The Committee members were drawn from DoE, DoM, NEMC, MWEM, MoA and the Department of Forestry, the Ministry of Industries and Trade, the University of Dar es Salaam, and CEEST.The team of core and coopted researchers were organised under the following categories of sectors for the study of emissions:-

• energy and transport;
• industrial activities;
• agricultural activities;
• forestry and land use;
• commercial and household energy use; and
• solid waste and wastewater management.

This report is the national inventory of Tanzania, and presents the findings of the study team. A base line inventory of sources and sinks of greenhouse gases for Tanzania is being presented. While a lot of gaps do exist in the data available and that which is required for a detailed inventory, the work highlights areas where further research is needed for such an undertaking, including that of establishing country specific emission factors.The aforesaid notwithstanding, the study team is of the opinion that work done thus provides for an adequate basis for priority ranking of emission sources and sinks to allow for concentration of efforts towards the more significant of these. A basis also exists for embarking on work related to mitigation of greenhouse gas emissions and assessment of vulnerability and adaptation to climate change.Finally the study team proposes that a mechanism needs to be put in place for the continued updating of the inventory.
