Planetary boundaries, wellbeing & healthcare with Mia Heide (WELA) What does it actually mean for human health that we’ve now exceeded 7 out of 9 planetary boundaries – up from 6 out of 9 in 2023 – and how should healthcare systems respond? In this episode, we're joined by Mia Heide, engineer and researcher at WELA – Wellbeing Economy Lab, to unpack the latest science and what it implies for policy, practice, and care pathways. Sustainable Healthcare Podcast … We talk about:What the planetary boundaries framework is – and why it’s about hard limits, not “nice-to-have” goalsThe new 2025 assessment showing we’ve transgressed 7/9 boundaries, and what changed since 2023 How to downscale planetary boundaries to a country level (e.g. Denmark) using different sharing principles – equal per capita, capacity to reduce, historical responsibility, and “grandfathering” Why some principles give wealthy countries like Denmark a negative carbon budget, and why “equal” is not the same as “fair” The concept of decent living standards – what’s the minimum energy and material footprint needed to secure basic human needs globally? Health impacts of specific boundaries once we overshoot them, including:Climate change: extreme weather, heat stress, displacement and food securityFreshwater change: water scarcity, sanitation breakdown, conflict riskNovel entities (PFAS, microplastics, synthetic chemicals): cancer risk, hormone disruption, fertility impacts – and why this is hugely under-discussed in public health The uncomfortable paradox: we need to meet basic needs and stay within limits – and every tonne of CO₂ still counts Why healthcare decarbonisation must be seen in a two-way relationship:Healthcare activities impact planetary boundariesOvershooting those boundaries, in turn, undermines population health and health system resilience Where Mia still finds motivation and drive in 2025 – and why “a different world is possible” is not just a sloganAbout our guest – Mia Heide & WELA Mia Heide is an engineer and researcher at WELA – Wellbeing Economy Lab, a Danish, independent think tank working for a wellbeing economy where societal progress is measured by the ability to create good lives for all within planetary boundaries – now and for future generations.
