The new methodology, developed by FAO and partners, identifies areas within dairy production where greenhouse emissions can be curbed - for example, by changing feed composition or feeding practices, or improving the energy efficiency of equipment - and explains how those reductions can be measured and reported.
Importantly, it has been certified by Gold Standard, an independent body that evaluates climate projects under the UN's Clean Development Mechanism and ensures they deliver genuine emission reductions.
This certification is key to allowing smallholder dairy operations to receive internationally-accepted carbon credits in exchange for emission reductions. These can be sold on carbon markets - a potential revenue stream that creates a financial incentive for the dairy industry to go greener and opens new opportunities for small-scale producers to access investment funding for their farms.
"Investing in ways to make smallholder dairy systems more productive is an efficient way to simultaneously reduce greenhouse gas emissions and ensure food security," said Henning Steinfeld, chief of FAO's Livestock Information, Sector Analysis and Policy Branch. "This methodology will help to channel finance to projects that have real impacts on the livelihoods of millions of smallholder dairy farmers," he added.
He estimated that milk production will have to grow by 144 million tonnes by 2025 to meet rising demands.
