What is the green skills gap, and what can UK businesses do about it?

The green skills gap is the growing distance between the sustainability skills UK employers need and the skills their workforce currently has. Demand is rising far faster than supply, and it reaches ordinary businesses, not only the energy sector. The good news is that most of the gap in a typical SME can be closed with focused, practical training rather than new hires.

Green skills have moved from a niche concern to a mainstream business issue in a few short years. This article explains what the green skills gap is, how large it has become in the UK, what actually counts as a green skill, and the practical steps a business can take to close the gap in its own team.

What is the green skills gap?

The green skills gap is the shortfall between the sustainability related skills employers need and the skills available in the workforce. It has two sides. On one side, demand is climbing as businesses face regulation, customer requirements and net zero commitments. On the other, the supply of people with the right skills is growing much more slowly. The gap is the space between the two, and it is widening.

How big is the green skills gap in the UK?

The scale is significant, and every credible source points the same way.

The headline figures come from the energy transition, but the pressure is felt across every sector, because sustainability expectations now travel down supply chains and through tenders to businesses of every size.

What actually counts as a green skill?

It helps to split green skills into two types, because most businesses misjudge which one they are short of.

Technical green skills. Specialist capabilities such as carbon accounting, life cycle assessment, ISO 14001 implementation, energy management or building retrofit. A small number of people in an organisation usually need these.

Greening skills. Existing roles performed with a sustainability lens: procurement that assesses supplier ethics, finance that factors carbon into investment decisions, marketing that communicates credentials without greenwashing. This is where most of the gap sits in a typical business, and it is often overlooked because it does not carry the word green in the job title.

Why does the green skills gap matter for my business?

Three reasons make this a commercial issue rather than an abstract one.

It affects your ability to win work. Corporate customers and public sector buyers increasingly score sustainability and social value in tenders. If your team cannot answer the questions credibly, you lose ground to competitors who can.

It affects recruitment and retention. With demand outstripping supply, people with green skills are in a strong position and command rising salaries. Businesses that develop these skills internally are far less exposed than those that rely on hiring them.

It affects data quality. Much of the data behind ESG reporting and carbon baselines depends on staff across the business understanding what to record and why. A workforce with basic sustainability literacy produces better data with less effort.

Is the answer to hire or to train?

For most businesses, and especially SMEs, training existing staff is the more realistic and cost effective route. The market for experienced sustainability professionals is competitive and prices are rising. Green skills are also highly transferable, which means a capable finance, operations or procurement person can usually be upskilled to apply a sustainability lens to work they already understand. Hiring a specialist still makes sense for genuinely technical needs, but it rarely removes the need to build literacy across the wider team.

How do we close the green skills gap in our own team?

A sensible, staged approach works better than a single large intervention. We structure this using our Five Step Model (Assess, Develop, Implement, Engage, Transform).

Set a baseline. Understand where your organisation and your people sit today. The free Enveglas ESG Progress Checker is a quick way to establish a starting point.

Map roles to needs. Look at your obligations and impacts, then work out which roles need which skills. Not everyone needs the same thing.

Prioritise. Build broad literacy across the workforce first, then applied skills in the functions that touch impact, data and buyers.

Choose the right format. Short bite-sized modules suit broad awareness, workshops suit applied skills, and accredited qualifications suit those who need in-depth capability.

Embed and measure. Fold sustainability into how you already work and measure the change in behaviour and outcomes, not just course completions.
