World-leading thought and action on climate and sustainability
How could you thrive in a sustainable world?
We help organisations of all sizes to understand the issues facing humanity, the role they can play, and how to thrive in the volatile world ahead. We help you engage with the challenges, find the opportunities, play your part, and tell your story. We'll make you anthropocene-fit.
​
We don’t offer box-ticking. Organisations should exist to benefit people and planet. If that’s not your aim, we may not be the right fit. If it is, we’re here to help—wherever you are in your journey.
​We know where numbers can help – and when you need something more.
​
If you need help calculating your carbon footprint using the most in-depth and custom research, or you want to explore the many ways you could become truly sustainable, our expert team will give you evidence-based assessments and inspire you to take impactful actions.
Carbon accounting alone doesn’t make you sustainable, but it's an important piece of the jigsaw.
We’ve been leading the industry for many years, offering system-complete, transparent, realistic, robust, and practical carbon accounting.
We count everything and show you where and how to take action.
Our Multi-Regional Input-Output model (SWC MRIO) helps you to calculate the most reliable, system-complete carbon footprint.
We give you a transparent methodology and specialist one-to-one support so you know exactly what your emission factors contain.
Total Carbon is an approach to carbon accounting that counts absolutely everything in the supply chains of all products and organisations.
With 3 datasets, methodology and support, you can use spend-based and life-cycle analysis data, without the serious errors that often occur when these two methods are simply mixed together.
We help every part of the food supply chain understand how to optimise your role in food production, nature recovery, climate, and livelihoods.
We measure emissions across landscapes and map your priorities to your landscape to show how every parcel of land fits with your vision.
We've counted the carbon in all kinds of industries
We have over 20 years of experience working with organisations from telecoms and finance to manufacturing and retail. We know the emissions in everything from an email to a pair of trainers.
We've also got expertise and a research background in looking at food and land. We've measured the carbon footprint of a tub of ice cream and a whole National Park.
​
Small World's global impact
We're proud to work with companies like Cogo, Ecologi and Sage, which use our data to help 1000s of businesses and individuals measure their carbon footprint, the first step in taking action to reduce it.
Our work with clients like BT Group is helping it lead the way in low-carbon telecoms. And helping the team at AMRC to think big about sustainability has them leading the whole of UK manufacturing to a sustainable future.

Big Picture sustainable thinking
We look at your organisation in the context of the emerging polycrisis, not just carbon numbers.
​
We help you explore the opportunities and threats in new ways, so you could truly thrive in a sustainable future.
