UNSPSC 81171901: Air quality science service

Consulting, advisory, information and research services from tertiary qualified professionals to advise on the contamination of the air by impurities (called pollutants) which can occur naturally or can be produced by human activities

UNSPSC 81171901 Air quality science service is a Commodity code. State and local governments buying under this code procure consulting and technical services focused on quantifying, monitoring, and planning for air pollutant emissions and indoor air quality compliance. Recent solicitations show demand for emissions inventory development, air quality testing and monitoring, and regulatory compliance support. The South Texas Development Council is procuring PM2.5 emissions inventorying, ambient air quality monitoring, pollution-level modeling, and regional air quality planning for Jim Hogg, Starr, Webb, and Zapata Counties under RFP AQR72026, due June 5, 2026. Broward County Port Everglades solicited development of a 2025 activity-based air emissions inventory quantifying mobile, indirect, and cargo-related emissions across port facilities, with proposals due June 8, 2026. Rockland County (New York) is procuring greenhouse gas emissions inventory and climate action plan development under RFP-RC-2026-016, due June 30, 2026. Issuing bodies include regional development councils, counties, and port authorities; school districts and cities appear in the recent activity block but predominantly for environmental testing and indoor air quality compliance rather than emissions science work. The Texas Procurement and Support Services division operates TxSMART Buy, a cooperative purchasing vehicle offering pre-negotiated indoor air quality equipment and services contracts to Texas state agencies, universities, and school districts.

Geographic activity concentrates in Texas (South Texas Development Council region, TxSMART Buy statewide), Florida (Broward County), and New York (Rockland County). East Lyme Public Schools (Connecticut) solicited a state-mandated five-year indoor air quality inspection report due March 26, 2026. The code sees steady but dispersed demand across regions; no single state or issuing-body type dominates recent postings. Most opportunities are RFPs with fixed-price or cost-reimbursable structures, populated by environmental consulting firms and engineers with emissions modeling and indoor air quality credentials. HUB subcontracting plans and DBE certification requirements apply to several Texas procurements. Response windows typically span 30–60 days from posting.
