The Hidden Environmental Costs of AI Ft. Dr. Miriam Aczel w/Anita Nowak - Purposeful Empathy
AI is impacting every part of our lives—and we need to start paying more attention. Listen to this thought-provoking conversation with Dr. Miriam Aczel, a sustainability and environmental justice researcher at the United Nations University Institute for Water, Environment and Health, whose research explores the hidden carbon, water, and land footprints of artificial intelligence. We discuss: The environmental costs behind AI—and why focusing on energy use is not the whole story Why “green” AI is more complicated than simply switching to renewable energy How AI has the potential to drive powerful climate solutions Why empathy and environmental justice must shape how we build AI—especially for communities bearing most of the environmental costs If you’re concerned about the impact of AI on climate change and climate justice—you don’t want to miss this conversation. 00:00 Preview 00:42 Episode introduction 03:21 About Dr. Miriam Aczel 02:14 Miriam’s backstory 08:56 Miriam discusses the UN report “The Environmental Cost of Artificial Intelligence: Carbon, Water, and Land Footprints” that she authored 10:02 The physical infrastructure hidden behind “the cloud” 14:09 Why AI’s environmental footprint depends on where its infrastructure is built 17:50 What the fracking industry can teach us about the rapid expansion of AI infrastructure 21:00 Are AI data centers repeating the extractive patterns of traditional energy industries? 26:18 Why running AI queries at off-peak times reduces their environmental impact 27:45 How AI can improve wildfire prediction and model sea-level rise 33:40 The UN’s new AI Environmental Transparency Initiative 36:14 How smarter prompts can reduce AI’s energy consumption 38:47 How to reduce AI energy consumption by being intentional about the model you use 45:34 Dr. Miriam Aczel’s Purposeful Empathy story Episode #11 of Empathy in the Age of AI part II, a special 25-part series: https://tinyurl.com/exyw2nua CONNECT WITH MIRIAM ✩ LinkedIn https://www.linkedin.com/in/miriam-aczel-ph-d-693b8066/ ✩ Website https://unu.edu/inweh/about/expert/miriam-aczel CONNECT WITH ANITA ✩ Email purposefulempathy@gmail.com ✩ Website https://www.anitanowak.com ✩ Buy a copy of Purposeful Empathy http://tiny.cc/PurposefulEmpathyCA ✩ LinkedIn https://www.linkedin.com/in/anitanowak/ ✩ Instagram https://tinyurl.com/anitanowakinstagram ✩ Podcast Audio https://tinyurl.com/PurposefulEmpathyPodcast ✩ Bluesky https://bsky.app/profile/anitanowak.bsky.social SHOW NOTES ✩ The UN AI Environmental Transparency Initiative https://unu.edu/inweh/news/un-secretary-general-launches-ai-environmental-transparency-initiative-calling-ai ✩ Environmental Cost of AI’s Energy Use https://walkearth.org/wp-content/uploads/2026/06/unu-inweh-report-the_env_cost_of_ai-2026.pdf ✩ Environmental Cost of Artificial Intelligence: Carbon, Water, and Land Footprints https://unu.edu/inweh/collection/environmental-cost-of-AIs-Enrgy-Use-Carbon-water-and-land-footprints ✩ MIT Climate Change Engagement Program https://climateproject.mit.edu/education/climate-change-engagement-program Video edited by Jad Misri, Green Horizon Studio
