Unlike CO2, methane only needs to reduce and stabilise, rather than go to net zero.
DairyNZ was one of the 10 primary sector organisations involved in He Waka Eke Noa.
A collaborative approach was important for the agriculture industry, McGougan said.
"Getting everyone together and formulating what will best suit our sector is what He Waka Eke Noa is all about," he told The Country Sport Breakfast's Brian Kelly.
He Waka Eke Noa's recommendations recognised the work that had already been done on each farm individually, which was a better outcome for Kiwi farmers, McGougan said.
"Rather than just a blanket ETS, which is basically a tax, this way is incentive-driven."
These incentives would help farmers decrease emissions and invest in technology, he said.
"It gives us options as farmers to do better, rather than being told what to do."
Pricing hadn't been set yet, but He Waka Eke Noa had recommended a cap of 11 cents per kg on methane for the first three years.
McGougan believed this wouldn't be a prohibitive cost for farmers, especially when compared to the Emissions Trading Scheme.
"It will be at the Government's discretion what the offsets are but hopefully it won't be at the ETS [pricing] because if things are at the ETS [prices] we'd be going out of business pretty quickly."
The Government will now consider the partnership's advice alongside advice from the Climate Change Commission, before making decisions later this year on how agricultural emissions are to be priced from 2025.
