The Economic and Social Commission for Asia and the Pacific (ESCAP) is the most inclusiveintergovernmental platform in the Asia-Pacific region. The Commission promotes cooperation amongits 53 member States and 9 associate members in pursuit of solutions to sustainable developmentchallenges. ESCAP is one of the five regional commissions of the United Nations. The ESCAP secretariat supports inclusive, resilient and sustainable development in the region bygenerating action-oriented knowledge, and by providing technical assistance and capacity-buildingservices in support of national development objectives, regional agreements and the implementation ofthe 2030 Agenda for Sustainable Development.

Copyright © United Nations 2026Tracking Number:ESCAP/4-TR/62 Executive Summary Air pollution remains a major global health risk, contributing to approximately 7.9 million deathsannually and ranking as the second leading risk factor for premature mortality worldwide.Particularly,indoor air quality (IAQ) has emerged as an important public health and environmental managementissue across the Asia–Pacific region. Aspeoplespend a large proportion of their timeinsidebuildingssuch as homes, workplaces,schoolsandhospitals,indoor environments represent a major source ofexposureto air pollutants.Poor indoor air quality has been associated with respiratory andcardiovascular diseases, allergic conditions, reduced productivity and negative learning outcomes.Despite increasing recognition of these impacts, indoor air quality management remains unevenlydeveloped across ESCAP member States. Literature reviews, survey responses and consultations with member States indicate substantialvariation in IAQ policy frameworks, monitoring capacity, institutional arrangements and technicalresources across the region. While some member States have established national IAQstandards,monitoring programs and regulatory systems, many others rely on voluntary guidance, buildingventilation standards or general environmental health regulations.Identified common challengesinclude limited technical expertise, insufficient monitoring data, unclear institutional responsibilitiesandnot yet establishedpractical implementation guidance. At the same time, member States expressedstrong interest in practical and step-by-step guidance that can be adapted to different national contextsand levels of institutional capacity. In response to these needs, this guideline presents aThree-TierFramework for indoor air qualityguideline valuesand management applicable to selected facilities and public indoor environments. Theframework is designed to support progressive development of IAQ management systems rather than asingle uniform regulatory approach. The three-tier structure reflects different levels of policydevelopment and implementation capacity. Tier 1 represents an entry level focused on basic monitoring,risk reduction and awareness-building measures. Tier 2 supports more systematicIAQmanagementthrough routine monitoring, standardised procedures and facility-level management programs. Tier 3represents an advanced level of IAQ management, includingIAQvalues, compliance verification, andintegration of monitoring systems with building management and digital technologies. The guideline provides recommended IAQvalues, monitoring approaches and management practicesforthree broad indoor environment categories: public facilities, residential buildings and general indoorworkplaces. Within public facilities, educational and healthcare facilities are presented as priorityexamples because they involve vulnerable populations and prolonged or repeated exposure. Thesefacility types were selected because they represent environments where people spend significantamounts of time and where exposure to indoor air pollutants may havesignificant he
