He is the author of acclaimed books, including There is No Planet B: A Handbook for the Make or Break Years, and How Bad Are Bananas? The carbon footprint of everything. He is a professor at Lancaster University, where his research includes supply chain carbon modelling, sustainable food systems and the environmental impact of ICT. He has made numerous speaking, radio and television broadcast appearances to promote public awareness of sustainability and climate change issues.
Dr Dmitry Yumashev
Principal Land Consultant
Dmitry has a background in applied mathematics and started his career as an aerospace scientist. He subsequently developed an interest in sustainability, and has worked on a range of projects with partners from academia, the private sector and UK Government. His contributions include scenario and uncertainty analysis of Arctic climate feedbacks and of soil carbon sequestration potential in the UK, as well as estimates of UK’s electronic waste flows to aid recycling. Dmitry is thrilled to work with SWC on assessing decarbonisation and carbon sequestration options for UK businesses in line with the 2050 Net Zero target.
Dr Sarah Donaldson
Sarah has a background in Ecology and Environmental Sciences, and completed a PhD in Plant Physiology at Lancaster University in 2018. She leads a variety of projects, including GHG audits for a range of organisations, carbon footprinting training courses, media and public communications work, and development of carbon calculator tools.
Assistant to Mike Berners-Lee
Mairéad has a BA in Law from Cambridge University and an MSc in Philosophy and Public Policy from the LSE. Her thirst for understanding the world has taken her from projects mapping coral reefs in Madagascar, to studying in Japan, to human rights work in rural Uganda and even management of an Irish pub in Kampala. It was from ski touring in the Arctic that her personal experience of the changing environment focused her efforts on the climate emergency. With 20 years of Executive Assistant and office management experience, Mairéad ensures Small World runs smoothly and supports the team with project administration and client liaison.
Dr Hannah Wright
Hannah has contributed to environmental conservation projects and developed ecological and agronomic research across the globe. She completed her MSc and PhD in soil and crop sciences at Lancaster University. Since, she has delivered carbon accounting projects for a range of businesses and organisations and continues to expand this work. Hannah has a special interest in the development of holistic nature-based solutions for resilient ecosystems and communities, and is building expertise in the application of specialised carbon accounting tools and approaches to sustainable land use projects.
Dr Tom Davies
Tom has a background in Molecular Biology and studied for a PhD in photosynthesis at The University of Sheffield. Whilst at Sheffield he co-authored a sustainability audit that formed the basis of the university's sustainability strategy and campaigned for the university to switch to a clean energy supplier. Tom also undertook a PhD placement at Small World Consulting in 2020, working extensively on the updated version of How Bad Are Bananas? Returning to SWC in 2022, Tom now works on various consultancy projects, including the development of carbon calculator tools.
Dr Tom Higgs
Tom has a background in physics, having studied at Royal Holloway and Cambridge, completing his PhD there on superconducting spintronics. While continuing to work in physics during the pandemic, Tom became more concerned with working on the challenges to overcome the climate crisis. He had previously followed his interest in sustainable transport to work as a smart mobility engineer. Tom enjoys applying his training in precise yet systemic thinking to carbon accounting and consultancy work.
