Framework alignment notes

i
SBTN: Rate of nutrient (nitrogen or phosphorus) loading in wastewater streams, indicating whether these are discharged directly to the environment or sent to waste-water treatment by a third party
ISO 14046 - data describing water quality (including for water withdrawal, release and water receiving body) emissions to air, water and soil that impact water quality

Target example
i

[Company name] will reduce their rate of nutrient load into wastewater streams in [basin] by [target percentage]% by [target year], compared with a baseline of [baseline percentage]% in [baseline year]. They will also indicate the source of this discharge, whether it is discharged directly to the environment or treated by a 3rd party.

Target source: Adapted from SBTN Freshwater Target

Additional Metric Notes
i

ACT-D stage: Assess Maturity stage: Advancing Metric Contribution to Action: Tracking nutrient loading helps mitigate eutrophication risks and supports responsible nutrient management. Observations/Successes/Challenges: > Requires on-site monitoring > Nutrient pollution often originates from diffuse sources, making it hard to attribute emissions to specific companies. > Nutrients may be diluted in some areas but highly concentrated in others, leading to localized environmental damage. > Nutrient runoff is influenced by rainfall, soil type, and climate, making year-to-year comparisons complex.
