Where is Global Warming Potential coming from?

• >60% from primary sector

(CH4 has 25 times higher

impact on GWP than CO

₂

)

• 10-20% from processing

• 15% consumer

Milk is nutritious and sustainable!

Conclusions

1. Optimization of current processes will not really help us,

innovation in the entire production chain is needed!

2. To avoid high economic risks, companies have to develop

innovative process technologies together

3. Be critical, be aware of subjective interests and do you your

own calculations on climate impact of food production

(including dairy)
