How the SME Climate Hub's Carbon Calculator Tracks Scope 3

How technology can help to demystify supply chains

This launch signifies more than just the introduction of another calculator.

For SMEs integrated into global supply chains, it marks a transformative approach to how carbon data can influence procurement and strategic decisions.

Emitwise’s contribution makes enterprise-grade emissions tracking attainable for smaller entities.

Emitwise, a platform specialising in carbon accounting, is frequently utilised by procurement teams facing supply chain complexities.

Its system leverages primary emissions data — sourced directly from suppliers or measured activities — to facilitate informed decision-making aimed at reducing Scope 3 emissions.

This category is particularly challenging as it includes aspects from raw materials to transportation and distribution.

“By enabling SMEs to access such tools, we are fostering real supply chain decarbonisation,” says Ian Hind, Head of Partnerships at Emitwise.

“Through our partnership with the SME Climate Hub, small businesses are now empowered to manage their carbon footprint more effectively.

“The expansion of the Hub’s free suite of tools ensures that even more SMEs can begin decarbonising, thus accelerating meaningful climate action across supply chains.”

The significance of this initiative lies in the fact that SMEs account for approximately 40% of global business-related emissions and contribute to half of the global GDP.

While larger corporations often have dedicated sustainability teams, SMEs typically lack such in-house resources.

Providing these businesses with access to high-quality, free tools opens pathways to improved data, greater transparency and, ultimately, reduced emissions across various industries.
