The methodology behind the game
The FAO LEAP road testing
LEAP is an FAO United Nations multi-stakeholders initiative that is committed to improving the environmental performance of livestock supply chains, whilst ensuring its economic and social viability.

From 2016 onward, it has published 11 guidelines that help the industry to perform environmental analysis of animal productions.

The LEAP partnership took the effort in 2020 to give a harmonized approach to the environmental assessment of feed additives in livestock supply chain. After a public review, the LEAP additive guideline was published and entered the ‘road testing’ phase.

DSM, together with Blonk Consultants, road tested the LEAP additive guideline with a state-of-the-art LCA report, to assess the impact of feed additives on animal production and test the available LCA methodologies.
This is a multi-species, multiple-feed-additive-intervention and multiple-impact categories study, whose title is “The applicability of LCA guidelines to model the effect of feed additives on the environmental footprint of animal production”.
The baseline
The baseline animal farm systems defined in the study are meant to depict a Western European type of production system. This is a relatively high producing system that relies on high quality feed ingredients . For this, a mix of Dutch and Belgian data was used for the farm and feed systems.
This game displays 4 life cycle stages of the production process of 1kg of milk (fat and protein corrected milk - FPCM). Milk processing and end distribution are not included. It enables you to make variations of some parameters to explore how different variables affect the overall environmental footprints of 1kg of milk.
