Context and Objectives

European dairy production systems (DPS) face many challenges across the three pillars (3P) of sustainability. The MILKEY project will develop a holistic approach for achieving 3P sustainability of DPS targeted to key European regions. Greenhouse gas (GHG) mitigation is a core aim of MILKEY, along with analysis of other environmental impacts and of economic and social factors that influence the functioning of this sector.

MILKEY will:

  • establish a unified analytical protocol to facilitate comparison and synthesis of GHG emission mitigation and sustainability assessments across the DPS case studies and key European regions.
  • use qualitative methods such as in-depth interviews with farmers and a variety of quantitative tools, such as life cycle assessment and economic-biophysical modelling.
  • focus on assessing 3P sustainability interactions and mitigation potentials for key European areas. It will assess flexible concepts for sustainable milk production and identify co-benefits and trade-offs.


The MILKEY projet will follow this workplan:


Expected results

MILKEY will approach the challenge of measuring and reporting actual reductions in GHG emissions by developing a biophysical-economic tool at the farm level that includes the necessary information about the most promising mitigation options for reporting purposes and makes them directly applicable to an individual farm.
