Land Use Change
The impact of Land Use Change (LUC) on climate change is included in Agri-footprint® 2.0 as a separate flow, allowing users to choose if they want to include LUC or not. Life Cycle Assessment (LCA) practitioners can easily include LUC in their sensitivity analysis if they wish. The comprehensive model used is the PAS 2050-1: Land Use Change Assessment Tool. This direct land use change (dLUC) is based on country averages modelled in the tool.
Direct Land Use Change Assessment Tool
The ‘Direct Land Use Change Assessment Tool’ provides a predefined way of calculating greenhouse gas emissions from land use change. These emissions arise when land is transformed from one use to another. A well-known example is deforestation for the cultivation of crops such as soybean and oil palm.
The tool gives insights in the emissions for a specific country and crop combination and attribute them to the cultivated crops. However, not in every case the previous land use is known. In this case the tool uses averages of land use change in the specific country, based on data from the database of the Food and Agricultural Organization of the United Nations (FAOSTAT).
Recently the tool has been updated, including the most recent statistics.

Three functionalities of the Direct Land Use Change Assessment Tool
- Country known, land use unknown
Provides an estimate of the GHG emissions from land use change for a crop grown in a given country if previous land use is not known. This estimate is based on a number of reference scenarios for previous land use, combined with data from relative crop land expansions based on FAOSTAT data.
- Country & land use unknown
The calculation of an estimate of the GHG emissions from land use change when both the country of production and previous land is not known. A weighted average is determined based on FAO statistics, using the same methodology as in 1) for calculating the GHG emissions for each relevant country.
- Country & land use known
The calculation of GHG emissions of land use change when the previous land use is known. All these approaches are described in the PAS 2050-1 published by BSI, and are made operational in this tool using various IPCC data sources.
