This report contains the greenhouse gas results of the land use, land-use change and forestry sector (LULUCF) for Vienna. This balance was estimated as part of a work package of the “Vienna Urban Carbon Laboratory” (VUCL) project.
The LULUCF greenhouse gas balance of Vienna represents an average net sink of around 11,000 tons of CO2eq. per year for the years 2018–2020. This net sink is mainly determined by the sink capacity of the forest in Vienna, which absorbs net approx. 43,000 tons of CO2 per year. The settlement category in Vienna is the largest source of emissions in the LULUCF sector and releases an average of 29,000 tons of CO2eq. per year. The other land use categories are minor sources.
The proportion of vegetation, especially trees, in Vienna is an important lever that can determine whether the LULUCF sector is a net source or sink.
