UNSPSC 77121500: Air pollution

UNSPSC 77121500 Air pollution is a Class code spanning environmental compliance, monitoring, and emissions analysis work that state and local governments procure to meet federal and state air quality mandates, remediate contaminated sites, and track greenhouse gas progress toward climate targets. State and local buyers under this code include environmental agencies, departments of transportation, counties, municipalities, and school districts. The work ranges from operational air monitoring station management and stormwater compliance consulting to greenhouse gas inventory development, climate action planning, and environmental site assessment for brownfield remediation. Recent solicitations include the Town of Simsbury's RFP for MS4 stormwater compliance and industrial stormwater permit services (due July 14, 2026), the Georgia Department of Transportation's RFQ for environmental support services across NEPA, air quality, noise, cultural resources, and ecology disciplines (SOQ due August 17, 2026), the Texas Commission on Environmental Quality's RFP for continuous PM2.5 air monitoring station operation and maintenance at Big Bend National Park (proposals due March 23, 2026), and Rockland County's RFP for greenhouse gas emissions inventory and climate action planning services (proposals due June 30, 2026).

Activity concentrates in Connecticut, Texas, Georgia, and New York, with additional solicitations from California, Utah, and Florida. The code reflects mixed issuing-body participation—state environmental and transportation agencies compete alongside county and municipal procurement offices—with no single buyer dominating recent postings. Scope varies substantially: some solicitations focus on technical operations (air monitoring equipment maintenance, laboratory analysis), while others emphasize policy and planning deliverables (emissions inventories, climate action plans, stormwater management plans). Insurance, qualifications, and performance standards are consistent across opportunities, with multi-year contract terms and competitive evaluation on technical capability, cost, and relevant experience the norm. Set-asides and preferences appear selectively—HUB and DBE requirements surface in Texas TCEQ procurements; MWBE preferences in Rockland County; local business preferences in some municipal and county RFPs—but are not universal across the code.
