Climate change and air pollution are two of the most challenging global environmental problems. While the idea of integrating action on air quality and climate is no longer new – the role of air pollutants in climate change has been gaining significant attention in recent years – linking air pollution and climate change policies more closely remains a challenge. The IASS has collaboratively led a number of workshops and conferences to increase dialogue and engagement on the topic of air quality and climate, including the scientific and policy communities as well as non-governmental organizations. One of the challenges associated with integration is the assessment of mitigation options. Challenges made all the more challenging because while air pollutants and GHGs are often emitted from the same sources, their effects on radiative forcing and human health, as well as their spatial and temporal distribution, vary wildly. One of the main focus areas of the latest workshops has been on metrics. How can metrics be used to assess and help identify co-benefits and trade-offs? Are the metrics currently in use sufficient? Are new developments needed? And if metrics are applied to this context how should they be stress tested in advance to avoid misleading informational biases for decision-making? Application of appropriate metrics that are well rooted in science and yet easy to understand are crucial to decision-making. Results from these dialogues and workshops will be presented.
