Static chambers to measure crops’ nitrous oxide emissions.
Fitting necklaces to measure cows’ methane emissions.
Gas chromatography to measure out greenhouse gas.
The environmental performance dashboard, to trace all incoming and outgoing flows on the farm.
PerfAgro P3, simulating the impact of the implementation of different technical options on three parameters: Profit, Planet and Population.

Results of the 1st carbon assessment of the farm in 2006
Total : 17 000 000 MJ fossil fuel and 2 800 tons eq. CO2 in 2006.
Fossil fuel consumption of 100 persons ;
Greenhouse gas emissions of 440 persons.
The Grignon farm feeds 7500 to 9500 persons.

Actions taken since 2005
High milk productivity/cow (approx. 10 000 L milk/cow/year).
Minimal soil work (no till whenever possible).
Introduction of more
legumes in crop
rotation.
Cows grazing when they are not in
production.
Cattle diet change (rape cake, industry co-products…).
Improvement of the agricultural waste management practices.
Energetic crops field trial.

The path to progress….
- 40% fossil fuel consumption-17% greenhouse gas emissions

The Grignon yoghurt fossil fuel and carbon profile in 2008
*Agricultural production: item including the production of milk at the Grignon farm (60%) as well as the milk powder incorporated to the yoghurts (40%).

An example of innovation:Chaff* harvest
*Chaff is made up of glumes, hulls, unthreshed heads and pods, short straw, leaf
material, and whole or cracked kernels or seeds from cereal, oilseed and pulse crops. Weed seeds are also a major component of
chaff.

The “triple win” benefits of chaff harvest
Partial weeding > less herbicides use Helps soil work minimization > less fossil fuel consumption Can be used for animal feed or as renewable energy in a biomass
boiler > optimization of the global energy balance

An example of innovation:Biomethanization
Biomethanization or biogasification is the process of decomposing biomass with anaerobic bacteria to produce biogas.
Farm waste
Urban waste: restaurants
grease, grass-cutting, etc.
Heat + electricity

Biomethanization: a “triple win” industrial ecology project
In 2012 a biomethanization unit will use 10 000 tons of cattle and diverse urban waste to produce 660 toe renewable energy. The Grignon farm will produce more energy that it needs. 81% of the current total carbon emissions will be avoided thanks to this project.
