The research project mainly contributes to the improvement of the national emissions inventory. Lacks of limestone usage were identified in the field of resource emissions. All input of limestone and lime in any branches of the economy, the relevance for emissions, as well as the consideration in the German emissions inventory were analysed and acquired for any relevant item of the balance sheet. Items of balance which have been taken into the inventory in 2006 were made available, including all new and detailed information. The entire limestone and lime balance for Germany is represented there. The emissions in the base year 1990, which were definitely determined with the coverage for 2006, were adjusted to about 3.5 million tonnes carbon dioxide. Therefore the completeness of the inventory has been increased.
