The 30 UK tech scaleups tackling climate change to watch

Tech Nation has announced the 30 scaleups that have been selected to join the new Net Zero programme. Announced in Alok Sharma’s speech today at London Tech Week, the companies come from across the UK and across a range of sectors including construction, agriculture, and energy.

The cohort includes companies that are building electric vehicles, creating vertical farms and animal-free dairy products, measuring environmental footprints, and improving manufacturing and recycling supply chains. These companies represent the most promising UK scaleups contributing to the UK reaching its goal of net zero greenhouse gas emissions by 2050.

In a new report, published today, Tech Nation found that the UK leads Europe for the number of Net Zero companies, at 323 compared to 207 in France (35% less) and 150 in Germany (53% less). Furthermore, 37% of UK Net Zero companies are at an early stage of growth, showing an impressive pipeline for the sector. 26% of UK Net Zero companies are late-stage, highlighting the growth already happening to meet emission targets. In 2019, the UK also led Europe for VC investment into Net Zero companies at £336mn in VC investment, 55% more than France which received £216mn, and 18% more than Germany with £283mn. VC investment in Net Zero in the UK has grown by 28% from 2018 to 2019. 

The government-backed initiative is the first of its kind, designed to accelerate the growth of the UK’s most promising Net Zero scaleups. Sessions will include quantifying sustainability, navigating the regulatory landscape, and how to internationalise a Net Zero business. The programme comes at a critical moment, with COVID-19 highlighting the key role played by technology in aiding a green recovery to the crisis and the importance of building a sustainable future.

The programme is supported by partners BNP Paribas, who bring their expertise to scaling up climate action. The partnership will support the collective mobilisation of clean tech solutions, which are a vital part of accelerating the transition to a low carbon economy. Companies selected to join were assessed through a rigorous judging process. The judging panel included Hayden Wood, CEO, Bulb, Pippa Gawley, Founder and Director, Zero Carbon Capital, Mark Hodgson, Chief Business Officer, Cervest, Tom Adeyoola, NED, Verco, Dr Ben Caldecott, Director of the Oxford Sustainable Finance Programme at the University of Oxford, Helen Clarkson, CEO, The Climate Group, Jeff Eneberi, Director, Sustainable Seaweed and Azeem Azhar, Founder, Exponential View.

In addition to the 30 companies joining the Net Zero cohort, four additional ‘Fellows’ will join the programme. The Fellows selected are net zero companies at a later stage of funding, or are alumni of Tech Nation growth programmes. The Fellows will have access to the Net Zero coaching sessions and peer-to-peer learning opportunities. The Fellows will also share their learnings and experience as net zero companies who already have experience scaling within this unique space.

Business and Energy Secretary Alok Sharma said: “As part of our plan to reach net zero emissions by 2050, we are funding green startups and unleashing the talent and creativity of entrepreneurs across the country.

“Innovative companies like these will help us to create green jobs and build back better as we recover from the coronavirus pandemic.”

Gerard Grech, Chief Executive, Tech Nation, commented: “The UK's Net Zero sector already leads Europe for VC investment, at £336mn, and is home to 323 tech companies that are working hard to reduce carbon emissions globally. Scaling such businesses can be hard, which is why we are delighted to launch a new programme focused on businesses at this stage of growth from all over the UK, especially given the impact they will have on climate change and their drive towards a net zero economy.”

Zheela Qaiser, Programme Lead, Net Zero Programme, commented: “All 149 applications we received for the Net Zero programme were excellent, showcasing the richness of solutions that small teams of innovators are working on to help us make monumental changes to the way our human world and systems impact our planet. I’m so impressed with our final cohort, and am looking forward to helping them work through the unique challenges that net zero companies face.”

Anne Marie Verstraeten, UK Country Head, BNP Paribas, commented: “Supporting Net Zero in the UK requires collective mobilisation, and clean tech solutions are a vital part of accelerating the energy transition. As a bank supporting the transition to a low carbon economy, we have a responsibility to connect our ecosystem of clients and the innovative start-ups at the forefront of developing technologies that tackle environmental challenges. This partnership with Tech Nation highlights the power of coalitions that is essential to scaling up climate action and creating a fairer, greener and more resilient world.”

Mark Hodgson, Chief Business Officer, Cervest, Judge for the Net Zero programme, said: "I was hugely impressed by the high standard of submissions for Tech Nation's Net Zero Programme. These inspiring, growing companies are creating a more resilient economy and I look forward to working with them to drive the UK's Net Zero ambitions forward.”

Susannah McClintock, Investment Director, Sustainable Ventures, Judge for the Net Zero programme, said: “It is fantastic to see how these exciting UK companies are contributing to the enormous challenge of achieving net zero; the applications showed the depth of innovation and talent in startups and early stage working to address climate change through commercial solutions."

Revannth N Murugesan, Co-founder and CEO, Antonym said: “Having been through Tech Nation Rising Stars in 2019, we are very aware of the huge scope of opportunities that came our way through Tech Nation. As a company, our vision is to accelerate the UK's low carbon economy by decarbonising transportation, and we are sure by being part of the Net Zero programme, we'll be able to achieve this effectively with the support from Tech Nation.”
