What is Nutrient Neutrality?
“A means of ensuring that development does not add to existing nutrient (nitrogen and/or phosphorus) burdens of the surrounding water environment” - NHS Property Services, 2020.
Nutrient Neutrality is achieved when a developer proves that their development will not increase the amounts of Nitrogen or Phosphorus in a sensitive water environment. When high levels of Nitrogen and Phosphorous enter a watercourse, they disrupt natural processes and impact wildlife and water quality. These nutrients come from agricultural activity, sewage and its treatment, septic tanks and industrial processes.
Following a November 2018 ruling in the European Court of Justice, Natural England advised Local Planning Authorities that planning permission should not be granted for a project unless it can prove that it will achieve Nutrient Neutrality.
Nutrient Neutrality must be achieved ‘in perpetuity’, meaning that mitigation must remain in place for 80 to 120 years.
