The ambitions are high and the chains both aim to develop an approach that is widely applicable and that will also be widely available. This prompted Wageningen University & Research (WUR) to start a four-year programme (PPP).


Same goal, different approach

The activities of both dairy chains form the environment in which the approach and instruments for the reduction of greenhouse gas emissions are developed. Both chains started in 2022 with a group of dairy farmers to make and implement reduction plans.

Pilot companies

The plans include measures such as ration adjustments, the application of grass/clover mixtures and manure digestion.  In addition, innovations are tested and calculated integrally. The pilot companies are located on different types of soil (small, peat, sand) and work with different strategies (from high-tech to nature inclusive). This diversity offers opportunities to learn which measures work best in which situation.


Based on the research, the approach focuses in the first year mainly on the following components, where an important starting point is that ultimately an approach with associated instruments is developed that enables scaling up to large numbers of dairy farmers.

  1. Create company-specific plans with data from the KringloopWijzer for individual dairy farms aimed at substantial emission reductions with appropriate measures for the business situation.
  2. The further development of the approach for planning and progress monitoring. The applied approach is evaluated and combined with the most recent scientific insights on change processes. Upscaling plays an important role in this.
  3. Getting facts straight. Greenhouse gas emissions in dairy farming are still a relatively new topic. It is useful to list the facts in factsheets in a practical and accessible way on certain topics. With new reduction measures, it becomes clear what the principle behind them is and in which situation they work. Another topic that will in any case be discussed is the (im)possibilities of carbon sequestration.

Cooperation in the chain is needed

The dairy farmer does not have to and cannot do it alone. The PPP therefore also collaborates with a number of (mixed) feed companies (Agrifirm, ForFarmers, De Heus and Duynie) and with Lely (supplier of equipment and robots for dairy farms) and Rabobank. The dairy chains themselves are working with groups of dairy farmers. PPP Agro Advies supports dairy farmers in making their reduction plans.
