51toCarbonZero has been named in the Sifted 100 UK & Ireland 2026, Sifted’s annual ranking of the fastest-growing startups and scaleups across the region. The recognition places 51toCarbonZero among the UK and Ireland’s fastest-growing technology businesses and highlights the growing importance of climate technology, carbon accounting and ESG as commercially critical categories.
We’re proud to share that 51toCarbonZero has been included in the Sifted 100 UK & Ireland 2026, a respected annual ranking from Sifted, one of Europe’s best-known startup and technology publications.
For us, this is more than a growth milestone. It is recognition that the market for climate intelligence, carbon accounting and ESG is becoming more commercially important, more visible and more central to business performance.
What gives the ranking real weight is its methodology. The Sifted 100 is a data-led list based on revenue growth over the past three financial years, with companies required to submit supporting financial documentation as part of the process. Inclusion reflects sustained commercial momentum, not just profile or market attention.
In this year’s ranking, 51toCarbonZero was listed at #92 overall and was one of just two companies featured in the Climate – Carbon Accounting & ESG category. It is especially encouraging to see this category recognised as a distinct space in its own right, reflecting the growing role of climate technology in helping businesses manage risk, improve reporting and drive measurable operational value.
That recognition becomes even more meaningful in the context of the wider report. Sifted notes that climate had a record nine companies included in this year’s ranking, despite a tougher backdrop for climate tech more broadly. That signals something important. This is no longer a niche conversation. Businesses that help organisations turn sustainability into practical, commercially relevant action are increasingly part of the mainstream growth story.
That shift is exactly where 51toCarbonZero is positioned.
We work with organisations that need to move from climate ambition to measurable operational action. Our AI-powered platform brings together enterprise data, emissions intelligence and decision support to help businesses identify where carbon can be reduced fastest and at lowest cost, while improving regulatory readiness, operational efficiency and long-term resilience.
Put simply, we believe the climate transition is a business transformation, not just a reporting exercise.
That matters because many organisations are now under pressure from boards, investors, procurement requirements and regulation, while still relying on manual processes, disconnected systems and overstretched internal teams. Our model is designed for exactly that challenge. We combine software with expert advisory support, including scenario planning, ROI modelling and dedicated Climate Success Managers, so clients can move faster and act with greater confidence.
The growth behind this recognition has been built on outcomes that matter to clients. Across our work, clients have achieved 100% audit pass rates and 42% resource savings compared with traditional consultancy approaches. More broadly, our client work shows how better climate data and execution can strengthen investor confidence, improve procurement outcomes and unlock measurable operational value.
That is why this recognition matters to us.
Being named in the Sifted 100 UK & Ireland 2026 places 51toCarbonZero among the region’s fastest-growing technology businesses, while also highlighting the rising importance of Climate – Carbon Accounting & ESG as a category in its own right. More than that, it reinforces something we have believed for some time: when sustainability is approached in the right way, it does not sit outside business performance. It improves it.
We’re grateful to our clients, partners and team for helping us reach this point.
And we see this as a milestone, not an endpoint.
As more organisations look to turn climate commitments into credible, commercially valuable action, we remain focused on helping them do exactly that. Get in touch if we can help your organisation.
