Achieving the European Union’s 2050 climate goals requires a collective effort from individuals, policymakers, industries, civil society organisations, and researchers. While systemic change is critical, empowering individuals to make sustainable lifestyle choices is equally essential. The PSLifestyle project has worked to bridge this gap, providing citizens with tools to measure and reduce their carbon footprints while offering policymakers valuable data to inform impactful policies. After four years of implementation, the PSLifestyle project is coming to a close in 2025.
