Deadline for CLO Applications: 6pm Friday 27th February 2026
The Next CLO Award Ceremony: June 2026, Manchester (Further Details TBC)

In June 2026, we will hold our seventh Carbon Literate Organisation (CLO) Awards! Which means, now is the time to apply for CLO accreditation.

Engaging with Carbon Literacy and becoming a CLO is a proven way for organisations to accelerate their climate action, show their commitment to the low-carbon agenda, and help reach net-zero targets.

Whether you have been delivering Carbon Literacy for years or only recently begun your roll-out, a rapid shift to zero carbon is what the science requires of every person, product, and organisation. So, capitalise on CLO accreditation now to accelerate your organisation’s trajectory towards a low-carbon future.

What is a CLO?

Carbon Literate Organisation (CLO) accreditation offers organisations a visible ‘badge’ that showcases commitment to Carbon Literacy. Organisations accredited as a CLO have a substantial proportion of their workforce certified as Carbon Literate and take significant actions to accelerate a low-carbon culture.

Why become a CLO?

A Carbon Literate Organisation will typically experience decreased in-house energy and resource consumption, improved organisational profile, healthier and happier staff, a healthier working environment, a safer supply chain, lower variable costs, enhanced competitiveness, and reduced commercial risk. CLO accreditation also demonstrates an organisation’s corporate social responsibility in the clearest possible way.

The CLO Awards ceremony

At last year’s CLO awards ceremony, we recognised 84 newly accredited CLOs from a wide range of sectors. CEOs and sustainability leaders from CLOs in the UK and internationally shared their experiences with Carbon Literacy, videos of which are available to watch via our  YouTube channel. For further insight into what you can expect from the awards ceremony, take a look at our snapshot of the CLO Awards 2025.

Due to the continued growth in the number of organisations achieving CLO accreditation in the past year, we expect the CLO Awards 2026 to be packed with awardees from a vast range of sectors, all coming together to celebrate their achievement. We hope to see you there, too!

What do I need to do to secure a spot?

This depends on where your organisation is in its Carbon Literacy journey:

• If your organisation has already been  accredited as a CLO  since March 2025, you do not need to do anything. You will automatically receive an invitation to the 2025 award ceremony via email closer to the time.
• If your organisation had previously been accredited as a CLO before March 2025, you could apply to upgrade to the next tier.
• If your organisation is rolling out Carbon Literacy but has not yet applied for CLO accreditation, you can apply to become a CLO (at any tier for which you meet the requirements).
• If your organisation is entirely new to  Carbon Literacy, contact us by email ([email protected]) or by phone (0161 298 1782), and we can advise you on the most effective ways to accredit your people and organisation.

How to apply

If your organisation is interested in becoming accredited as a CLO for the first time or upgrading to a higher tier, please follow the link to our Carbon Literate Organisation Pack, which contains everything you’ll need to apply, including information on the fees and application criteria.

Deadline to apply

To make the deadline for the next wave of CLO accreditations and secure your spot at the CLO Awards 2026, applications must be completed and submitted to The Carbon Literacy Project, with the appropriate fee, by 6 pm Friday 27th February 2026.

Please apply with plenty of time, so we are in the best position to assist you with your application and any queries.

Please note: You can still apply to become a CLO at any point after this deadline. You will receive your digital certificate as soon as you are accredited, but you will be invited to and awarded your trophy at the 2027 awards.
