[Call for action: the health sector as a driver of societal transition towards Planetary Health].

Humanity is facing existential challenges that require urgent action to address the triple planetary crises. Drawing on the principles of planetary health, the paper argues that health professionals and the health sector have historically been important drivers of societal change, and that time has come once again for the sector to take up such active roles in addressing the planetary-health challenges. The paper provides an overview of the current frontlines of planetary health in the Netherlands: in education, research, new governance and sustainable leadership, as well as in various movements for greater transformative connection and transdisciplinary collaboration.

Turning green: the impact of changing to more eco-friendly respiratory healthcare - a carbon and cost analysis of Dutch prescription data.

Objectives: Dry powder inhalers (DPIs) and soft mist inhalers have a substantially lower global warming potential than pressurised metered-dose inhalers (pMDIs). To help mitigate climate change, we assessed the potential emission reduction in CO equivalents when replacing pMDIs by non-propellant inhalers (NPIs) in Dutch respiratory healthcare and estimated the associated cost.

Design: We performed a descriptive analysis of prescription data from two national databases of two independent governmental bodies.
