Dairy Processing - January/February 2022 - 47

" It's coming out of the farm gate emissions - cradle to farm
gate on a dairy farm is globally around 90-plus percent of
emissions - and the dairy food supply chain curves on the
dairy farm. "
Methane (CH4) is a gas produced largely from bacteria
that live in soil, water and the stomachs of ruminant animals,
such as cows. Methane is considered a greenhouse gas (GHG)
because it can trap infrared radiation in the atmosphere,
causing an increase in air temperatures. Methane is the
second most abundant global man-made GHG, behind carbon
dioxide (CO2), According to a report by Sustainable Dairy in
conjunction with the University of Wisconsin-Extension.
Methane, once emitted, will exist in the atmosphere for
12 years, which is shorter than the lifetime of CO2. However,
methane is able to trap more radiation compared to CO2
resulting in much greater global warming potential. Overall,
methane represents 16% of annual GHG emitted to the Earth's
atmosphere based on its Global Warming Potential.
While there are challenges for the dairy industry in
reducing its carbon footprint, there is plenty processors can
do to have an impact. DFA is doing its part by supporting
advances in feed efficiency, herd nutrition and feed additives
designed to reduce emissions and using renewable energy
methods, such as solar panels and wind power, on farms and
in processing facilities.
Land O'Lakes, Inc.'s on-farm sustainability commitments
are on track to be adopted by its more than 1,600 memberdairy
farms by 2025. By that target date, all Land O'Lakes'
dairy farmer-owners will complete an intensive, on-farm
sustainability assessment aligned with the US Dairy
Stewardship Commitment while maintaining universal
compliance with the National Milk Producers Federation's
(NMPF) National Dairy Farmers Assuring Responsible
Management (FARM) program.
" What climate science is telling us is the sense of urgency
is now, " Weller said. " So, what's happened is a response.
We have global governments, full supply chains, individual
companies now realizing that sense of urgency. They are
making global commitments and they are now looking
for solutions. "
