Lorraine is highly skilled in business change and project management with an MBA, possessing a rich experience in health and social care and major capital programmes.  A key example being client project manager for an award winning £40m new build mental health hospital. The 2015 Boxing Day floods prompted Lorraine to change career from the NHS to study an MSc in Conservation and Biodiversity at Lancaster University. After interning with SWC, Lorraine now specialises in the application of research to land use, with a keen interest in natures carbon sinks e.g. peatland, wetland and forestry carbon sequestration.


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. 


Mairéad Brown

Executive Assistant

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 and teaching in Japan, to human rights work in rural Uganda and even management of an Irish pub in Kampala. She has travelled and resided extensively across four continents, but it was through ski touring in the Arctic that her personal experience of the rapidly changing environment focused her concerns and efforts on the climate crisis. 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.


Matt Jones


Matt has a BA in Geography from the University of Oxford, where he specialised in conservation research and ecology. At Small World he primarily leads projects focused on understanding where clients fit in to the big picture of tackling the climate crisis, going beyond just their emissions. Matt has successfully delivered valuable insights to a range of organisations on their climate journey, with a specific focus on reshaping the way the asset management industry thinks about its climate responsibility.


Charlie Rogers

Junior Consultant

Charlie has a background in biology and earth sciences, having graduated from the University of Bristol with a degree in Palaeontology and Evolution. She grew her passion for science communication whilst volunteering for the Bristol Dinosaur Project, and first got involved with Small World in early 2020, working with Mike on giving his ‘There Is No Planet B’ talks. With a particular interest in the last 66 million years of climate change during her degree, she is keen to apply her knowledge of past climates and to develop her skills to pursue a career in sustainability at Small World.

Dr Dmitry Yumashev


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.


Rosie Watson


Rosie has a first-class degree in Environment and Business from the University of Leeds. She has assisted with various projects at Small World since 2017, including researching for and editing Mike’s book There Is No Planet B, and contributing to research into the global food system. She has experience working for sustainability-related charities and business-networks, in the UK and abroad.  She was recently away for over a year, attempting to run from the UK to Mongolia, on a climate-communication adventure called the New Story Run. She made in 4800km to the Black Sea, before being stopped by covid-19 restrictions, but hopes to continue when possible. While back at Small World, she is expanding her work with clients, assisting with their carbon foot printing as well as big picture strategies. 

Laura Turner

Phd Internship

Laura is a PhD student at the University of Nottingham studying how Arctic ecosystems respond to environmental change. Whilst studying at the University of Sheffield she was a campaign coordinator on the Sustainability Committee where she co-led a group which successfully advocated for the University to switch to a clean energy supplier. She contributed to the report this campaign was based on, and also to the development of University’s first Sustainability Strategy. Laura began here placement in March 2021 and is assisting on various consultancy projects.


Alex Boyd


Alex is a graduate from Lancaster University having studied for an MPhys in Physics, Astrophysics and Cosmology. After graduating, he undertook an internship with a local sustainability charity researching methods to estimate the potential energy generation from solar PV in Ambleside. Alex began an internship with SWC in March 2020 and since then he has quickly developed an interest in EEIO modelling and carbon accounting as well as assisting with various consultancy projects including GHG audits, menu calculators, and assessment frameworks. Alex has recently begun a PhD programme in partnership with SWC and the Centre for Global Eco-Innovation. He is working on developing a global, multiregional EEIO model to help companies better assess their scope 3 emissions.


Gwen Harrison


Gwen is an independent climate change and sustainability consultant with nearly 20 years’ experience. She has worked with private, public and third sector organisations on projects covering a wide range of topics including low carbon energy, buildings, communities, land management and food systems. She has an MSc in Carbon Management from the University of Glasgow, and an earlier MSc in Petroleum Geology from Imperial College. She has worked with SWC on numerous carbon footprinting and sustainability projects over the last 8 years.


Dr Robin Frost


After leaving Cambridge with a degree in computer science, Robin spent twenty-five years in business, working initially in the banking industry, then the food industry for eighteen years based in Yorkshire. With an increasing interest in sustainable business, he undertook an MSc in Environmental Informatics at Lancaster University. Whilst there he met Mike which led to him undertaking a PhD with Small World on estimating supply chain emissions in organisations. During and after the PhD Robin worked with Small World using and enhancing the technique of Environmentally Extended Input-Output modelling and applying it in a variety of settings. A move to Edinburgh and a new position working with Scottish Government has not ended his interest in sustainability and he provides advice and assistance in his spare time.


Tom Davies

Phd Internship

Tom is a PhD student at The University of Sheffield, studying the regulation of photosynthetic light harvesting in plants. He also co-authored both a sustainability audit for The University of Sheffield in 2018, and a report advocating that the university switches to a clean energy supplier in the same year. Pursuing his interests in sustainability and climate change, Tom began a placement at SWC in January 2020, working on an update to How Bad are Bananas? and various consultancy projects.
