The problem nobody's naming

The people writing your sustainability story are rarely the ones trained to tell it.

In most UK businesses, the marketing team writes the campaign. The PR team drafts the press release. The sales team answers the tender question. The procurement team asks the supplier. The founder writes the LinkedIn post. And the sustainability lead, if there is one, sits somewhere else in the business, reviewing after the fact or not at all.

 

That worked when nobody was watching. In 2026, everybody is watching. The Advertising Standards Authority has been actively ruling against carbon and sustainability claims. Almost every ruling names the advertising copy, not the underlying carbon accounting. The Competition and Markets Authority has stepped up green-claims enforcement under the Green Claims Code (CMA). 

What Net Zero Academy does about it

The measurement isn't usually where UK businesses fall down on sustainability. The communication is. Net Zero Academy trains the people who write, brief, answer, and post, so the story your business tells stands up to scrutiny.

Reduces your greenwashing risk.

The ASA is actively ruling on carbon and sustainability claims, and most rulings name the advertising copy, not the underlying carbon accounting work.

Builds team confidence on carbon.

In meetings, in tenders, on LinkedIn, on stage, your team stops avoiding the sustainability question because the wording no longer feels quite so risky.

Puts you ahead on net zero rules.

ISO 14068-1:2023 replaced PAS 2060 in November 2025, and most of the UK market has not yet caught up. Your team will, and your competitors mostly will not.

Protects your brand from bad claims.

One badly worded claim can take years of PR and legal work to unwind. Training the people writing your sustainability story is the cheapest insurance you can buy.

The foundational course. Built to give every named role above the same working literacy in carbon and climate, so that when they write, brief, answer, or post, they know what they're saying.

Who Net Zero Academy is for

Marketing and content teams. The people writing your net zero content, running your campaigns, briefing your agencies, and answering "can we say we're carbon neutral in this ad?" Net zero Academy gives them the literacy to answer that question themselves

PR and communications teams. The people drafting your press releases, handling media questions, and running your LinkedIn presence. Net zero Academy gives them the standards and language they need to stand their ground in an interview.

Sales and business development teams. The people answering tender questions on carbon, sustainability, and environmental claims. Net zero Academy gives them the confidence to answer accurately without over-promising.

Procurement and supplier management teams. The people asking suppliers for carbon data, environmental credentials, and sustainability policies. Net zero Academy gives them the framework to ask the right questions and interpret the answers.

Founders, MDs, and senior leaders. The people writing board updates, investor materials, and public statements. Net zero Academy gives them a shared language and a defensible position.

Sustainability leads. Not because they need the foundations, but because they need the rest of the business to catch up. Net zero Academy is the tool that gets everyone else fluent enough to work with them.

Serious about credibility

Frequently Asked Questions:

What is Net Zero Academy?

Net Zero Academy is Carbon Neutral Britain's training programme for UK businesses. It is built for the people who communicate sustainability inside a business, marketing, PR, sales, procurement, and leadership, and is aligned to current UK certification standards including ISO 14068-1:2023 and the GHG Protocol Corporate Standard. Course 01 is available now. Further courses will follow.

Who is Net Zero Academy for?

Any UK business owner or team leader who needs their people to talk about sustainability accurately and confidently. Named audiences include marketing teams, PR teams, sales teams answering tender questions, procurement teams, founders, MDs, and sustainability leads. Both SME (10 to 250 staff) and mid-market (500+ staff) businesses use Net Zero Academy.

How is Net Zero Academy different from Carbon Literacy training?

Carbon Literacy Project training runs one-day whole-team awareness sessions accredited by CLP. Net Zero Academy is built for the specific roles that carry external communication risk, uses assessed learning with a 30-question test rather than an action pledge, and aligns to ISO 14068-1:2023 rather than to a training accreditation. Both can sit alongside each other. Many businesses will benefit from both.

Is Net Zero Academy accredited?

Climate Academy courses are aligned to the standards actually used in UK carbon reporting and certification, including ISO 14068-1:2023, ISO 14064-1, and the GHG Protocol Corporate Standard. CPD UK certification is in application. We deliberately position Net Zero Academy against the underlying standards rather than against a training-body accreditation, because the standards are what your business will actually be judged on.

How do I get access to Net Zero Academy?

Net Zero Academy is currently free for CNB certified clients. If you are already a CNB client, log in to your CNB account and Net ZeroAcademy will appear in your dashboard. If you are not yet a CNB client, Net Zero Academy becomes available as part of your certification. Talk to us about certification and we will get you set up on both.

What courses will you launch next?

We are focused on making Course 01 excellent before adding more. We do not publish a public roadmap until a course is committed. If you want to be first to hear about the next course, add your email to the Net Zero Academy notification list.

Can I buy Net Zero Academy without being a CNB client?

Not at this stage. Net Zero Academy launched in 2026 as part of the CNB service line, and we're focused on getting it right for our existing certified clients first. We expect to open it up more widely later in 2026. If you'd like to be first on that list, add your email to the Net Zero notification list, or start a conversation with us about certification
