Helping tech companies who are
creating a more sustainable future

What is Net Zero

Climate-tech scaleups play an outsized role in tackling the climate crisis. 40% of emission reductions rely on technologies not yet commercially deployed on a mass-market scale.  This is why Tech Nation is delighted to launch Net Zero 2.0, supporting scale-ups to achieve scale and accelerate the UK’s goal to drive down global emissions.

We are looking for early-stage scaleups which operate across key sectors, including electricity & energy, transport & mobility, agriculture, food systems, manufacturing and building technology. Companies may directly contribute to net zero, with emission-reducing and carbon capture technologies or may contribute indirectly by changing consumer behaviour, or increasing efficiencies.

Net Zero is tailor-made to help mission-driven founders realise their visions. The best part? It’s free to join and we don’t take an equity stake in your business.

As we have already closed our second callout for the Net Zero programme, you can pre-register your interest to be the first to hear about application opportunities.

Who is Net Zero for?

Net Zero is for fast-growth tech companies which help the UK reduce greenhouse gas emissions either directly or indirectly. Companies may work digital, hardware and life science sectors.

Criteria for applicants:

  • Headquartered in the UK
  • Potential and ambition to make an at scale impact 
  • Evidence that the product or service is beyond the minimum viable product phase
  • Proven evidence of some market traction
  • Grant funding or investment up to Seed or Series A or has revenues below £1.5m

What does the Net Zero programme involve?

Net Zero is a six-month, free growth programme for tech companies that are creating a more sustainable future. We run masterclasses, insight sessions and peer to peer networking events for our fast growth, sustainable cohort.


Founder focused sessions delivered by entrepreneurs who have lived the journey. Tackle fundamental growth barriers such as financing, sales, talent and culture.


Sessions for your leadership team to upskill themselves. Explore challenges faced in marketing, operations, finance, product, tech, and HR functions.

Sustainability sessions

Work with leaders, experts, influencers and stakeholders to quantify your company’s impact and potential in the tech ecosystem and on the planet.


Gain positioning as a fast-growth UK sustainability company through Tech Nation marketing and press. Be on the radar with government, corporates and investors.
