In 2012, over 80 organizations, including governments, supermarket chains, banks, animal feed suppliers, and civil society groups, signed the Grazing Covenant, aiming to encourage grazing for cows and maintain the number of dairy farms with grazing at a minimum of 81.2%, as per 2012 statistics. The success of the initiative is measured annually by the percentage of dairy farms that use grazing and the number of lactating cows that spend time outside during the grazing season. This information is tracked by both Statistics Netherlands and ZuivelNL, with the most recent results being published in December of each year.
