Net Zero Pioneers, an exclusive new report created by BusinessGreen featuring 50 cutting-edge businesses that are accelerating the development of a net zero emission economy, launches today. 

The Net Zero Pioneers report showcases the UK’s most innovative and impactful businesses working on the UK’s net zero transition, profiling the myriad ways in which they are working to turbocharge decarbonisation efforts in every corner of the economy. From energy and transport to industry and agriculture, from the emerging carbon removals sector to the evolving circular economy, from blue chips with centuries of heritage to start ups with nothing but a good idea and a dream of greatness, every corner of the UK business community contains pioneers who are mobilising to lead the pursuit of the UK’s net zero goals. 

Commissioned by the Net Zero Festival – which takes place from 31st Oct – 1st November 2023 at the Business Design Centre, Islington, the new report provides an invaluable insight into the breadth and reach of the innovation and investment that is turbocharging efforts to deliver on both corporate and economy-wide net zero goals. 

At a time when the UK’s net zero transition is under fire from some high-profile critics, the Net Zero Pioneers report provides an invaluable snapshot of the vibrant innovation ecosystem that is serving to catalyse the green economy and how these companies are playing a critical role in both accelerating progress toward net zero emissions and bolstering UK competitiveness.


James Murray, co-founder of the Net Zero Festival, said: “With the recent government rollback of key net zero policies, it is more important than ever to showcase the many brilliant businesses that are making remarkable strides to deliver net zero emissions across multiple sectors and industries. The Pioneers Report seeks to celebrate their efforts and demonstrate how the commitment to climate goals and targets is helping to drive the development of exciting new technologies and business models that will deliver multiple benefits to both individual consumers and the UK economy as a whole.”

The Top 50 businesses featured in the inaugural Net Zero Pioneers report are:
