Benchmarking: The Ultimate Catalyst for Better Air Quality Through Global Standards

This article first appeared on www.goaqs.org

Air quality is an invisible yet pervasive factor influencing our health, productivity, and overall well-being. While awareness of air pollution is growing, translating that awareness into actionable behavioral change remains a significant challenge. The key to unlocking this transformation lies in the power of benchmarking—a potent tool that, when coupled with global standards like the proposed Global Air Quality Standard (GO AQS), can empower individuals and communities to breathe cleaner air.

The Power of Comparison: Learning from Other Fields

The effectiveness of benchmarking as a driver for improvement is not a new concept; it has long been a cornerstone of success in diverse fields. Consider the world of athletics: elite athletes constantly benchmark their performance—speed, strength, endurance—against competitors in their category. This isn’t about shaming, but about identifying areas for improvement. A runner who sees their sprint times lagging behind others in their age group knows exactly where to focus their training. Similarly, in healthcare, patients track metrics like blood pressure or cholesterol against established healthy ranges or anonymized data from similar patient populations. This comparison provides a clear understanding of their health status, prompting necessary lifestyle changes or medical interventions.

A practical, personal example vividly illustrates this point: as an individual tracking my resting heart rate through an app that allows comparison against +56,000 users worldwide. Seeing a “superb” rating, indicating excellent heart aging, provides tangible positive reinforcement and validates my health efforts. Conversely, a less favorable comparison would flag a problematic area, encouraging focused action. This simple yet powerful mechanism of comparison fosters accountability and motivates behavioral adjustments.

Recommended CO2 Levels for Optimal Building Performance

Carbon dioxide (CO2) concentration is a critical indicator of indoor air quality (IAQ) and plays a significant role in building performance. While CO2 itself may not be directly harmful at typical indoor levels, its concentration serves as a proxy for ventilation effectiveness and the potential buildup of other indoor air pollutants, including pathogens, that can negatively impact occupant health and cognitive function. This article examines the relationship between CO2 levels and building performance, drawing upon research findings and expert insights to recommend CO2 levels that promote a healthy and productive indoor environment.

Understanding the Role of CO2 in Indoor Environments

CO2 is a natural component of the air we breathe, but its levels can increase significantly in indoor spaces due to human respiration and other combustion processes (candles, cooking, combustion heating, etc). When ventilation is inadequate, CO2 from these sources can accumulate, leading to elevated concentrations.
