SLU calculates and reports emissions and uptake from Sweden's Land use, Land Use Change and Forestry sector (LULUCF).
We are systematically working to reduce our negative impact on the environment and increase our positive impact. Our Environmental Management Systems (EMS) is certified according to ISO 14001.

Our single largest environmental remedial measure in Swedish freshwaters is liming the waters to reduce damage by acidification. It comprises significant monitoring by hydrochemical and biological sampling. The monitoring is conducted both regionally and nationally.
The regional monitoring of liming effects include both chemical and biological sampling. The chemical analysis primarily aims to assess whether the calcium doses are appropriate to fulfill the liming objectives. Therefore, it is usually limited to sampling during the most acid conditions, and only comprises a few hydrochemical parameters, typically pH, alkalinity and some measure of water colour or organic material content.
The national monitoring of liming effects commenced in 2007 with the target lake inventory. About 3 000 limed so-called target lakes were analysed with respect to chemical composition, during the autumns in 2007 and 2008. The sampling also comprised about 1 800 unlimed reference lakes. The inventory aimed to provide a basis for assessment of acidification of the limed lakes. In autumn 2010, a continuous programme with so-called cyclical low-intensity monitoring of limed and reference lakes was initiated. One sixth of all target lakes are sampled every hydrological year, once in autumn and once in the succeeding spring. A parallel programme for limed target watercourses and unlimed reference watercourses was initiated simultaneously.
