Academic Foundation and Early Career
Born in 1993 in Falkirk, Scotland, Hannah Ritchie built her expertise in environmental science at the University of Edinburgh. She first earned an undergraduate degree in environmental geoscience, followed by a master's degree in carbon management—the study of reducing and sequestering carbon dioxide to mitigate global warming.
Ritchie continued her doctoral studies in Scotland, focusing on the intricate relationship between malnutrition and global food systems. Her PhD thesis, Global food systems: addressing malnutrition through sustainable system pathways (2018), developed a scalable framework to analyze food system pathways. Her research specifically investigated whether it is possible to sustain a growing global population without causing further environmental degradation.
ไม่มีภาพประกอบResearch and Professional Impact
Ritchie began her professional career as a sustainability lecturer at the University of Edinburgh before transitioning to the University of Oxford. At Oxford, she focused on creating data visualizations—the graphical representation of information—to make complex data more communicable to the general public.
Contributions to Our World in Data
Joining Our World in Data in 2017 as Head of Research, Ritchie expanded her scope to include air pollution, deforestation, and energy. She gained significant global visibility during the COVID-19 pandemic by building the platform's comprehensive COVID-19 information dashboard. By 2023, she ascended to the role of Deputy Editor and Lead Researcher.
Advocacy and Public Engagement
Beyond her research, Ritchie is an active voice in policy and public discourse. In 2024, she was appointed to Scotland's Just Transition Commission, an independent body advising on the shift toward a low-carbon economy. She also reaches a wide audience through her newsletter, "Sustainability by Numbers," which has over 60,000 subscribers.
Her research often challenges common misconceptions. For instance, she has highlighted that for the majority of food products, the carbon footprint is minimally affected by the distance the food is transported.
Literary Works and Recognition
Ritchie has authored two significant books that synthesize her data-driven approach to the environment. Not the End of the World (2024) focuses on large-scale problem-solving and the possibility of ending climate change, while Clearing the Air (2025) provides a hopeful guide to climate solutions through a question-and-answer format.
