Chris Adams speaks with climate advisor Helen Neal about the growing regulations around environmental claims, including the EU’s Empowering Consumers for the Green Transition (EmpCo) Directive. They explore why greenwashing often results from poor communication between sustainability, marketing and legal teams, and how businesses can make credible, evidence based claims without falling into greenhushing. Helen also introduces her IMPACT framework and Zena Review, a tool designed to help businesses identify potential risks in their sustainability messaging.

This Week in Green Software, Dr. Nick Souter from the University of Sussex explores how researchers can reduce the carbon footprint of scientific computing without compromising research quality. He shares practical ways to measure and optimise the energy use of fMRI data processing, including how removing unnecessary steps from a pipeline can cut emissions by around 50%. The conversation also examines responsible AI use, sustainable data storage, and how certification initiatives can make sustainability a standard part of scientific research.
