In response to the need for urgent and decisive action to keep within the 1.5 - 2°C target of the Paris Agreement, the Pathfinder Initiative aims to increase motivation and capacity by showing how the implementation of well-designed policies and technologies can yield multiple benefits for people and planet.
Scientific oversight for the initiative is provided by The Lancet Pathfinder Commission, comprised of international experts in decarbonisation from key sectors, including energy, cities, food, transport and health care.
We provide practical, evidence based pathways to zero carbon through transformative local, regional and global actions. Our vision is to create a global community that delivers transformative solutions for a healthier, fairer and more prosperous post-carbon society.
Significant progress is still needed to create a healthy, ‘post-carbon’ future, no longer dependent on burning fossil fuels and other unsustainable practices, where human societies are thriving within planetary boundaries. To achieve this goal, transformative actions must be implemented on a local, regional and global scale.
The Pathfinder Initiative aims to assess and synthesise lessons from the implementation of practical, evidence-based pathways to zero carbon societies support evidence-informed decision making based on real-world case studies and robust scientific evidence. Highlighting knowledge gaps and identifying how to address the challenges of implementation across diverse settings, these pathways will enable significant improvements to be achieved with minimal delay with the aim of accelerating progress to a post-carbon society.
Funded by the Wellcome Trust and with support from the Oak Foundation, the Initiative is led by researchers at the London School of Hygiene & Tropical Medicine (LSHTM). The Lancet Pathfinder Commission will provide scientific oversight, where international experts across key decarbonisation sectors and disciplines will guide and inform the work for analysis.
The Initiative will also establish Champions to create a dedicated advocacy effort to effectively communicate findings and increase motivation for change. The findings will be published in The Lancet medical journal.
Pathfinder co-Chair Andy Haines was recently listed as no. 28 on Reuters list of the top 1000 most influential climate scientists in the world.

Please note the publications below include background material from previous research and products of the Commission.
Our call for case studies is now open.
To find practical pathways to zero-carbon by 2050, we need real-world examples from a range of organisations, people and cities.
By submitting your examples, you will have the opportunity to be referenced in our final lancet report and featured in our unique dashboard of case studies across the world.
We are looking for evaluations of actions that mitigate greenhouse gases and also benefit health and wellbeing. Potential impacts on health can also include risk factors, such as changes in air pollution, diets or exposure to extreme temperatures. Both successes and failures, as well as published and unpublished examples are invited.
Evidence can include actions taken by the public and private sectors, civil society and not-for-profit organisations. Actions can come from any sector, including energy, transport, agriculture and land use, oceans, industry, human settlements, health care, and education, and from nature-based solutions like conservation and restoration.
We also welcome evidence of cross-sectoral or systemwide actions, including actions at the nexus between mitigation and adaptation.
You will submit your evidence by filling out an online form and providing further information.
The case studies gathered by Pathfinder will be used to map the evidence for health benefits of carbon reduction actions, to indicate where the gaps are and to provide frameworks for action to help policy makers and other actors to decide where best to focus their resources. We aim to present initial results at COP26 in November 2021, and final results at COP27 in November 2022.
