Nutrient Trading in Lake Rotorua: Goals and Trading Caps

Abstract

For a nutrient trading system to achieve the desired environmental outcome, or goal, this outcome needs to be translated into nutrient flows and allowances. To connect the nutrient loss provided for under the allowances with the environmental goal, a number of decisions need to be made. These decisions will shape the nutrient trading system. This paper looks at the information and analysis needed to ultimately define allowances and set trading caps for a nutrient trading system.
