CO₂ Equivalencies
These equivalencies put the calculated Global Warming Potential into familiar terms for context. They do not represent transportation or operational impacts associated with the pipe.

Methodology, assumptions, and source data
Calculation Method
Project pipe mass = pipe weight (kg/m) × project length (m).
Each environmental result equals project pipe mass, converted to metric tonnes, multiplied by the material-specific environmental factor.
Diameter Availability
CSP and RCP comparisons are provided for pipe diameters from 300 mm (12 in.) through 3000 mm (120 in.). Larger CSP diameters are not included because equivalent RCP sizes are not available for a direct material comparison. HDPE results are shown only where an HDPE pipe-weight value is available.
Environmental impact factors and pipe-weight values in this calculator are based on the NCSPA-supplied EPD dataset used for this updated calculator. Final public-facing EPD title, declaration number, publication date, and system-boundary wording should be inserted here before publication.
