Increasingly, customers and investors are asking about supplier sustainability practices. For many SMEs, the biggest untapped lever for reducing emissions is the collective behaviour of the people in your organisation. Your staff make hundreds of decisions every week that affect your carbon footprint: how they travel, what they print, how they heat or cool the office, whether they flag wasteful practices they notice. Training and awareness programmes help translate your sustainability commitments into practical action across the whole business.

This guide explains how to build employee awareness of your organisation’s carbon footprint, embed climate action into your workplace culture, and develop the internal capability to make sustained progress on reducing emissions over time.

How this helps your business

Enables practical action: Reducing emissions requires more than just leadership commitment. By involving your entire team, you ensure that staff consistently make decisions that cut emissions in their daily work, driving measurable progress across the business.
Builds culture and retention: A clear commitment to sustainability, backed by employee engagement, is increasingly valued by staff. Businesses that actively involve teams in climate action report stronger engagement and retention.
Strengthens your sustainability story: Evidence of active employee engagement demonstrates that your commitments are being put into action.

How to build employee awareness and climate action capability

✅ Start with a baseline: know what your people already know

Before rolling out training or campaigns, it helps to understand your starting point. A short, anonymous survey can reveal:

How aware staff are of the business’s carbon footprint and net zero commitments.
Which areas of the business they think have the biggest environmental impact (and where there may be misconceptions).
What barriers they perceive to taking more sustainable actions at work.
Whether any staff already have relevant knowledge or enthusiasm that you can build on.

This takes 30–60 minutes to design and can be completed by staff in under five minutes. The results give you a clear foundation for prioritising where to focus your awareness efforts first, and a useful benchmark to measure progress against in future.

Don’t be discouraged if only a handful of people complete the survey, however, a low response may indicate the need for a different approach to engage staff. In these cases, consider hosting a brief discussion session or informal focus group instead. A face-to-face conversation can help win people over and encourage open sharing of views in a more dynamic way than a written survey. It also gives attendees the chance to ask questions and express concerns directly.

✅ Appoint a Green Champion

A Green Champion is someone within your business who takes on a voluntary role as an internal advocate for sustainability. They are not expected to be an expert and can be working at any level in the business. Their value is enthusiasm, visibility, and continuity: keeping sustainability on the agenda.

Practical things a Green Champion can do:

Share relevant news, tips, or resources with colleagues (for example via email, a Slack channel, or a noticeboard).
Coordinate low-cost engagement activities such as sustainability challenges, awareness weeks, or a suggestions box.
Act as a first point of contact for staff who have ideas or questions about the business’s sustainability efforts.
Feed sustainability-related observations and ideas back to management.

Smaller businesses may have a single champion; larger ones might build a small cross-functional group. The key is to ensure the role is genuinely supported by management with protected time to pursue it, rather than addeding, unfunded responsibilities on top of someone’s existing workload.

✅ Use free and low-cost training resources

You do not need a large training budget to build meaningful awareness. Several high-quality free resources are designed specifically for SMEs:

Sage University (sageu.com): Sage’s learning platform includes carbon accounting training covering how to measure and track greenhouse gas emissions, understand reporting methodologies, and calculate your business’s carbon footprint. Particularly useful for finance and accounting staff who will be involved in emissions measurement and reporting.
Sage Net Zero Hub (sage.com/en-gb/net-zero): A collection of practical resources, guides, and tools from Sage to help SMEs understand and act on their net zero journey, including content on carbon measurement, sustainability reporting, and supplier engagement.
Climate Fit (smeclimatehub.org): A free seven-module online training programme from CISL and the SME Climate Hub, covering governance, operations, supply chain, finance, and people. Modules are 20–30 minutes each and can be completed independently, making them easy to fit around busy schedules.
The Carbon Literacy Project (carbonliteracy.com): Offers a structured course kit for businesses, including slides, activities, and supporting materials. The course leads to a recognised Carbon Literacy Certificate for participants and can be delivered as a single full day or broken into shorter modules.
The SBTi Academy (sciencebasedtargets.org/academy): Free foundational modules on science-based target setting — useful for anyone involved in your sustainability strategy, reporting, or supplier engagement.

For businesses ready to invest further, organisations such as the Carbon Trust, Positive Planet, and the Cambridge Institute for Sustainability Leadership (CISL) offer bespoke workshops, e-learning platforms, and coaching programmes.

✅ Make training relevant to specific roles

Abstract training about climate change does not reliably change behaviour; practical guidance about what people can do in their specific roles does. When designing or selecting training content, link it clearly to the decisions your staff face day-to-day:

Operations and facilities staff: Energy efficiency, waste reduction, equipment purchasing, supplier choices.
Finance and procurement: Supplier sustainability questions, integrating carbon criteria into purchasing decisions, budget allocation for lower-carbon options.
Sales and account management: Articulating your sustainability credentials to clients, understanding customer sustainability requirements and reporting expectations.
All staff: Commuting choices, digital and AI usage habits, printing and paper reduction, reporting issues like equipment left on overnight.

✅ Communicate progress and celebrate action

One of the most effective ways to maintain engagement over time is to show that efforts are making a difference. This does not require sophisticated measurement, a simple annual update comparing this year’s energy bills, commuting survey results, or waste volumes to the previous year is meaningful.

Practical ways to maintain momentum:

Share a brief quarterly update on your sustainability progress with the whole team.
Recognise and celebrate contributions like a staff member who spotted a way to reduce energy use, or a team that successfully changed a supplier.
Tie sustainability milestones into existing recognition or reward structures where possible.
Use internal channels (email newsletters, Slack, noticeboards) to share tips, celebrate wins, and keep the topic visible.

Common Mistakes to Avoid

❌Treating awareness as a one-off activity: A single presentation or email rarely produces lasting change. Awareness needs to be reinforced regularly, through different formats and channels, over time.

❌Making it too abstract: Content that focuses on global statistics rather than your specific business footprint and the practical actions available to your team is unlikely to drive behaviour change. Ground messaging in the context of your organisation.

❌Assigning responsibility without giving time or resource: Nominating a Green Champion and then giving them no time, no budget, and no visible management support is counterproductive. It signals that sustainability is not genuinely valued.

❌Focusing only on individual habits: While personal behaviours matter, the biggest emissions reductions in most SMEs come from structural decisions like energy contracts, supplier choices, and travel policies. Awareness programmes should build understanding of personal and company-wide choices.

❌Waiting until you have a full strategy: Some businesses delay employee engagement until their emissions reduction strategy is fully developed. Starting earlier, with imperfect data and incomplete plans helps to builds momentum and gain useful ideas from staff.

Cost and Effort

Cost: Low

The most impactful awareness activities require little to no budget. Free training resources (Climate Fit, the Carbon Literacy Project, the SBTi Academy), a Green Champion model, and regular internal communications can all be implemented at minimal cost. If you choose to commission external trainers or bespoke e-learning programmes, costs will vary.

Effort: Low to medium

Initial setup: 3–5 hours to survey staff, identify a champion, and design a basic awareness plan.
Ongoing: 1–2 hours per month to maintain communications, coordinate any awareness activities, and keep sustainability visible across the team.

Conclusion

Reducing emissions requires decisions and behaviours to change across your whole organisation, not just in one person or one department. A structured approach to training and awareness helps embed this across your team by building the knowledge, motivation, and practical capability to take meaningful action. Better still, this does not require a large investment. The most effective approaches are those that are consistent, grounded in your specific business context, and actively supported by leadership.
