In a significant milestone for Trinity College Dublin’s School of Engineering, a team of academics has been awarded the prestigious 2023 Haagen-Smit Prize for their groundbreaking research on air pollution, published in the journal Atmospheric Environment. Professors Aonghus McNabola, Brian Broderick, Assistant Professor John Gallagher, and Adjunct Professor Prashant Kumar were recognized for their exceptional contribution to air pollution science.

Their award-winning paper, "Air Pollution Abatement Performances of Green Infrastructure in Open Road and Built-Up Street Canyon Environments: A Review," was a collaborative effort spearheaded by Professor Prashant Kumar of the University of Surrey’s Global Centre for Clean Air Research (GCARE). The research also involved experts from the U.S. Environmental Protection Agency, University College Dublin, Trinity College Dublin, and the University of Bologna.

Published in 2017, the paper has achieved wide recognition, with 791 citations to date. Its findings have gained attention beyond academia, being featured in 50 news stories and cited in over 20 policy documents, emphasizing its significant real-world impact.

The research has transformed the understanding of how urban green infrastructure (GI) affects air quality and public health. By reviewing global evidence, the study provided crucial insights into how GI can reduce air pollution, helping to address challenges related to climate change and human health.

In addition to highlighting the benefits of GI, the study offered best practices for its effective implementation to ensure optimal outcomes for air quality and human well-being. This comprehensive approach has shaped research agendas and influenced policies at local, national, European, and global levels.

The importance of the study’s findings is underscored by their inclusion in key policy documents and guidelines from bodies such as the United Nations, European Commission, UK Parliament, and City Hall London. The impact of this research continues to resonate worldwide, shaping discussions on urban green spaces, air quality, and climate change mitigation.

The achievements of Professors McNabola, Broderick, Gallagher, and Kumar highlight Trinity College Dublin’s research excellence and the importance of interdisciplinary collaboration in tackling complex environmental challenges. Their work stands as a testament to the School of Engineering’s commitment to advancing knowledge and promoting positive change for society and the environment.
