Professor Laurence Gill, from the School of Engineering at Trinity College Dublin, has been chosen as a Lead Author for the Intergovernmental Panel on Climate Change (IPCC) 2027 Methodology Report on Inventories for Short-lived Climate Forcers. This prestigious appointment recognizes Professor Gill’s expertise and leadership in environmental engineering and climate science. 

The IPCC plays a critical role in providing scientifically rigorous methodologies that guide countries in quantifying their greenhouse gas emissions. While previous reports have focused on key greenhouse gases like carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), the upcoming 2027 report will address Short-lived Climate Forcers (SLCFs). These include pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), non-methane volatile organic compounds (NMVOCs), sulfur dioxide (SO2), ammonia (NH3), black carbon (BC), organic carbon (OC), and hydrogen—many of which significantly impact global warming and air quality. 

SLCFs contribute to approximately half of global warming and have far-reaching consequences for human health and ecosystems. This new methodology report will provide countries with essential guidance on how to quantify and report emissions of these pollutants, ensuring more comprehensive and effective climate action. 

Professor Gill’s selection as a Lead Author underscores Trinity’s commitment to world-leading research in climate and environmental science. His contribution to this report will help shape global efforts to combat climate change and protect public health.
