Methodology used in FeedPrint: a tool quantifying greenhouse gas emissions of feed production and utilization

The methodology for calculating greenhouse gas emissions of the feed production chain is described in detail. Beside using existing guidelines, flexibility is realised by a systematic breakdown of the feed production chain into stages and a standardised method to calculate transport emissions, improved allocation is realized by detailed analysis of industrial processes. The calculation tool FeedPrint covers the complete Dutch Feed list, over 300 feed materials, sourced from countries all over the globe. Animal nutrition is incorporated in the tool to evaluate the ultimate effect of changing rations.
