Land Use Change

The impact of Land Use Change 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.

This tool for assessing direct land use change was developed alongside the PAS 2050-1 standard to provide a predefined way of calculating Built on GHG Protocolgreenhouse gas (GHG) emissions from land use change. This tool provides two basic functionalities. The first is to provide an estimate of the GHG emissions from land use change for a crop grown in a given country when the 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. The second functionality is the calculation of GHG emissions from land use change when the previous land use is known. Both these approaches are described in PAS 2050-1, published by BSI, and are made operational in this tool using various IPCC data sources. Both options work for specific country & crop combinations, where for the second functionality more details are required.

The PAS 2050-1 method is referred to by the Food SCP (ENVIFOOD) and the PEF standards.

You can download the tool, which is reviewed by the World Resource Institute and the WBCSD (GHG protocol), from the Blonk Consultants website.
