Why Metrics Matter: Evaluating Policy Choices for Reactive Nitrogen in the Chesapeake Bay Watershed

Why Metrics Matter: Evaluating Policy Choices for Reactive Nitrogen in the Chesapeake Bay Watershed

Primary Country: United States
Ecosystem: estuary
Sample Value Estimates:
  1. $4.4 billion / yr: damages per year caused by emissions of Nox from mobile sources (180,000 tonnes Nr/ye
  2. $108 million: damage attributed to nitrate loading of Chesapeake Bay
  3. $3.9 billion: damage attributed to human morbidity and mortality
  4. $10,000: marginal abatement cost per tonne of Nr from land based agriculture/nitrate (based on year $20
  5. $96,000: marginal abatement cost per tonne of Nr from land based urban and mixed open land uses/nitrate (yr $20
  6. $18,000: marginal abatement cost per tonne of Nr from freshwater based point sources/nitrates (yr $20
Region: Americas / Atlantic
