Fonterra says 34 per cent of its farmers now have tailored farm environment plans, up from 23 per cent at the start of the year.
The company has just released its latest sustainability report, which for the second year is including a triple bottom line of economic, social and environmental impacts.
Global Sustainability director Carolyn Mortland said another 1000 of the co-operative's 10,000 suppliers had farm specific plans compared to last year, many of them in higher risk catchments.
Mortland said there was a bottleneck of farmers wanting plans, and Fonterra was increasing its sustainable farm advisor pool from 30 to 40.
