Operation Zero

At HCWH Europe, our vision is that every European country develops a national decarbonisation plan for its healthcare sector. With the support of our project partners ARUP, we have established Operation Zero - a groundbreaking project to put the European healthcare sector on the path to net zero carbon emissions, in line with European and international climate commitments.

Designing net zero roadmaps for healthcare

Through Operation Zero, we have developed and piloted a new methodology that any national or regional health authority can use to measure its healthcare emissions and establish a decarbonisation roadmap that achieves net zero by 2050.


Designing a net zero roadmap for healthcare provides a framework to Front cover of publication Designing a net zero roadmap for healthcarecreate a decarbonisation roadmap for healthcare systems. This includes how to calculate a carbon footprint, model emissions trajectories, and develop the appropriate governance structures to support the process.

This technical methodology is primarily aimed at analysts working within national or regional health authorities, but also includes guidance for policy officials. It was piloted by three national and regional health authorities, ensuring that it is robust and ultimately drives action among European health systems.

National healthcare decarbonisation roadmaps

Phase one | 2021 - 2022

HCWH Europe initially partnered with three national and regional health authorities to develop and pilot this methodology, supporting them to generate detailed climate footprint analyses and decarbonisation roadmaps. Through these pilots, we gained valuable feedback on the practicalities and limitations of developing decarbonisation roadmaps that helped to build a more rigorous methodology.

Phase two | 2023 - ongoing

Building on the lessons learnt in phase one, we are now working with two further national health authorities to generate detailed climate footprint analyses and decarbonisation roadmaps for their health systems using the Operation Zero methodology. 

We are also developing a community of practice comprising health authorities that are driving action towards net zero carbon emissions within the European healthcare sector. They will help refine the methodology and ensure it is applicable to health systems across Europe and beyond.
