Model to measure methane emissions needs to change
Farmer and former politician Sir Lockwood Smith is questioning the way that methane emissions from livestock are measured in NZ.
So says Crowe Horwath’s agribusiness specialist, Sean Bennett.
While there is still debate on which of the three proposed Zero-Carbon Bill options will be applied, there are obvious benefits to be gained for farm businesses in establishing appropriate tree plantings, or retiring certain land areas to offset possible future emission liabilities, he says.
"Obligations of the ETS will also bring opportunities for farmers and it is vital the new policy is understood by those set to be impacted, including farmers,” he says.
“Farmers should ensure they are positioned to capitalise on opportunities, document their carbon footprint, and compare it to data on plant and lab-based alternate proteins.
“When we can accurately measure what we have on-farm, and wrap the right story around carbon neutrality, we can then effectively take that to market.”
Shane Jones, New Zealand’s Forestry Minister stated the government wants to “fix the ETS to make it more streamlined, accessible and flexible and give users more confidence and certainty,” Jones admits there has not been clear, consistent information around the ETS, further commenting “one of the proposed improvements is a consistent, transparent way of making a decision about the supply of ETS units.”
Current policy supports shelter and erosion planting as a method to create carbon credits.
“If farmers can build on programs already in place by becoming more strategic with plantings, there is potential for farm businesses to create another income stream,” says Bennett.
Assessing your exact carbon neutrality score requires input from carbon specialists, however, there are methods to develop a rule of thumb understanding of how individual farm businesses rank in carbon neutrality – 12ha of pines, willow or poplar trees/1000 sheep, or 5.7ha/100 beef cattle and 8.7ha/100 dairy cows are carbon neutral.
“Most sheep and beef farm businesses we have assessed have proved to be carbon positive or well on the way to being so,” says Bennett.
“Sheep and beef farmers have an easier road to being carbon neutral, with latest figures showing that 24% of natural vegetation is on sheep and beef farms. There will be a point where we need to work alongside the dairy industry, as all agri sectors will be grouped together from a legislative perspective.”
With significant gains to be made from the ETS, Bennett urges farmers to take the time to educate themselves on their carbon position and consider how they can use it to their advantage. “If used correctly, it is an instrument that can add real value to your farming business.”
