Land Use Change
The impact of Land Use Change (LUC) on climate change is included in Agri-footprint® 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
This tool for assessing direct land use change was developed alongside the PAS 2050-1 standard to provide a predefined way of calculating greenhouse gas (GHG) emissions from land use change.The tool provides three basic functionalities, based on three different approaches related to data availability of the user.
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.
The PAS 2050-1 method is referred to by the Food SCP (ENVIFOOD) and the PEF standards.
Download the tool
You can download the tool, which is reviewed by the World Resource Institute and the WBCSD (GHG protocol), from the website of Blonk Consultants.
