About us

The Earth, and every species on it, is facing a climate and ecological emergency. Small World Consulting exists as a response to that emergency.


We work with organisations of all sizes and in all sectors. We are world-leading experts in measuring the carbon and climate impact of full supply chains and operations. We measure the carbon footprint of landscapes and advise on sustainable land management. 


We look at the smallest details to the global big picture. We can help you see yourself thriving in a low-carbon future.

Our mission

Our mission is to help as many organisations as possible take meaningful action to become truly sustainable.

Our values

We say it like it is, we support our clients in facing every challenge, and we call out greenwash.

We'll push you to think differently, to set ambitious goals and to inspire others to join you on your journey to a sustainable future. We believe in taking action rather than waiting for perfection.

We try to uphold our values of honesty, kindness and respect for all people and species in everything we do.

Our team

The Small World team of consultants are specialists and are here to support you with every step. We use the spending data you already have and can delve into particular products and processes to get the most realistic picture of your carbon footprint.

Founded in 2005 by world-leading carbon footprint expert Professor Mike Berners-Lee, our team are specialists in carbon accounting, working with big companies like BT to small values-driven organisations like The Ecology Building Society and Jude's Ice Cream. We have specialists in sustainable land management, working with small individual estates like Holker to all 15 of the UK's National Parks.

Want to work with us?


If you share our values, are committed to tackling the climate crisis and are willing to do what it takes to reduce your emissions, we'd love to hear from you.
