Just launched: The new Biodiversity Footprint Calculator!
A free calculation tool by Plansup to assess both current and future biodiversity footprint of a company’s product at the landscape level. With the tool companies can test the effectiveness of presumed biodiversity friendly measures.
This tool calculates the biodiversity impact of your company’s supply chain, production process and transport that can be related to one or more products. With the calculator it is possible to calculate the biodiversity footprint for multiple scenarios. It is recommended to use the first scenario to describe the current situation and to use subsequent scenarios to describe all kinds of biodiversity friendly measures that are expected to change the footprint in the near future.
The methodology used in this calculator is based on the Biodiversity Footprint methodology developed by Plansup in collaboration with Wageningen Environmental Research (Alterra). The calculator is a limited version of the full Biodiversity Footprint method and focuses on the impact of the two most important pressure types on biodiversity: Land use and Green House Gas emissions. The impact is calculated for three parts of the value chain: Raw materials (/suppliers), Production process, and Transport.
The Biodiversity Footprint (BF) methodology is using parts of the internationally implemented GLOBIO methodology developed by the Netherlands Environmental Assessment Agency. In GLOBIO so-called ’cause-effect’ relationships are used (i.e. the effect of a pressure factor on biodiversity), based on the best available scientific knowledge. The local impact of pressure factors is determined in terms of the presence of species and the number of individuals per species. The BF method has been developed for the impact of three pressure types: Land use, Climate Change (via Green House Gas emissions), and Emissions of Nitrogen and Phosphorous into water. For the Dutch situation, the impact of Water extraction is added. By comparing the impact in the current situation with the impact in a new situation (after measures) the effectiveness of biodiversity friendly measures can be tested, not only afterwards but also in advance. On the basis of this method companies can assess their current impact on biodiversity and estimate their future impact after implementation of planned measures.
The biodiversity footprint is expressed in MSA.ha. MSA stands for Mean Species Abundance of original species, representing the intactness of the nature relative to the original state. The MSA value ranges between 0 and 1; 1 implicates that the area is undisturbed, and 0 for a complete loss of the original biodiversity. The MSA.ha footprint indicates the change of intactness within the area that is impacted for the product, multiplied with the extend of that area. The general equation for determining the biodiversity footprint is:
Footprint = ∑(ha area in use_i * [1-MSA_pressure factor_i])
in which i= land use, GHG
Please note that the method does not distinguish between current or previous conversion of land. Although the company cannot be held responsible for the destruction of nature that was caused many years ago by former users of the land, it is responsible for its current use of the land which prevents original biodiversity to restore.
The BF method is location specific while other methods such as Life Cycle Assessments use a regional approach and are less specific on the type of land use. As the biodiversity impact is highly dependent on the use intensity, a differentiation of land use types is essential for a correct biodiversity assessment.
The method for the calculation is explained in more detail in the webtool application itself.
