The 2025 EuroHealthNet Annual Seminar will begin by setting out the evidence of the health and health equity impacts of climate change, including the costs of inaction. Experts will explore what difference we can make – as public health professionals and beyond. How can we take action, advocate for, and achieve change, bringing everyone on board? A high-level policy panel will discuss how initiatives across sectors and across levels of governance can create a healthier planet and protect everyone's health and wellbeing.
