The research project "Carbon Dioxide Storage and Biomass Usage in Cities" investigates the potential of biomass usage for both carbon dioxide absorption and storage and its potential as a substitution for fossil fuels. The main objective of the project is to evaluate the potential of biomass to contribute to a decrease in carbon dioxide emissions through its use in energy production and building construction.

The project is organized in two modules:

In the first module, the CO2 emissions from the use of biomass from urban landscape management for energy generation are compared with the emissions of energy generation from fossil fuels. In the first step, the annual amount of biomass from urban landscape management areas is determined by use of Urban Vegetation Structure Types and characteristic values from external sources. The annual amount of biomass serves as a basis for the calculation of the technical potential for energy generation. The lifecycle of the energy generation is then analyzed in regard to CO2 emissions.

In the second module, the quantity of biomass usage in the form of timber construction materials or other building products made of renewable raw materials, is evaluated based on an analysis of construction practices. The target is the calculation of possible reductions of CO2 emissions. These reductions result from reduced emissions in the construction of timber materials compared to the emissions in the construction of alternative materials. Additionally, when incorporated in the building stock such biomass products store carbon dioxide for 70 to 100 years, therefore functioning as additional temporary carbon storage.

Dresden, Germany is taken as a specific case study in these investigations.
