Direct Land Use Change Assessment Tool
Calculating greenhouse gas emissions from land use change
Deforestation is one of the major issues facing the global agriculture production system, with as much 8% of global CO2 emissions being attributable to land use change. A well-known example is deforestation for the cultivation of crops such as soybean and oil palm. Many publications have focussed (rightfully so) on this issue and have provided solid global or country specific estimations of CO2 emissions due to land use change based on available statistics and/or satellite imagery
A big challenge for Life Cycle Assessments (LCA) researchers is to translate this impact of land use change to specific crops from specific countries while little primary data is available. Our ‘Direct Land Use Change Assessment Tool’ is specifically designed to address this challenge.

Update: version 2018
In December 2018 the Direct Land Use Change Assessment Tool has been updated. In this update we incorporated the latest data from Food and Agriculture Organization of the United Nations (FAO) up to 2016. Many of the background data have changed, such as areas reported, forest area statistics, and estimations of biomass carbon stock in forests.References to the tool
The ‘Direct Land Use Change Assessment Tool’ has grown in past years based on the PAS2050 and specifically the PAS2050-1 frameworks, the basic methodology of which is now widely referenced in. Examples are the PEF guidelines & Envifood protocol. It is the most comprehensive implementation of a methodology for GHG emissions from direct land use change that is widely applied.
Three functionalities
The tool provides three basic functionalities,
based on three different approaches related to data availability of the user.
Country known & land use unknown
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.
Country & land use unknown
A weighted average is determined based on FAO statistics, using the same methodology as in ‘country know & land use unknown’ for calculating the GHG emissions for each relevant country.
Country & land use known
These approaches are described in the PAS 2050-1 published by BSI and are made operational in this tool using various IPCC data sources.
Complete dataset is now available
