Executive Summary
Small businesses are increasingly expected to show credible carbon reporting especially in public‑sector procurement and within larger supply chains, but many find carbon reporting hard to start and even harder to maintain alongside day‑to‑day operational priorities.
This guide provides a practical, size‑appropriate approach to creating a Carbon Reduction Plan (CRP) that is fit for purpose for small businesses. It focuses on:
- What needs to be included (and what can be kept proportionate)
- How to collect the minimum viable data using records small organisations already hold
- How to publish, sign‑off and update a CRP in line with official procurement expectations
- How to avoid common reporting issues, particularly around Scope 3 and consistency.
For wider market context (barriers, drivers and why expectations are rising), see the supporting Market Briefing: Carbon Reduction Plans for Small Business.
This short video provides an overview of what’s covered in the guide, outlining how small organisations can approach Carbon Reduction Plans in a clear, practical and proportionate way.
What a Carbon Reduction Plan is
A Carbon Reduction Plan is a short, practical document that sets out an organisation’s emissions for a single reporting year, its commitment to reducing carbon, and the actions already taken or planned to achieve this.
For small organisations, it provides a straightforward way to explain how carbon is being managed and improved over time. It is commonly used to respond to procurement or customer requests for carbon information and to support consistent comparison, without needing to produce a full sustainability report or wider ESG documentation.
When Small Businesses are Asked for a Carbon Reduction Plan
Small organisations are most commonly asked for a Carbon Reduction Plans when:
- bidding for or supplying into in‑scope public‑sector procurement, and/or
- responding to customer and supply‑chain requests for emissions information and commitments.
Official procurement guidance and templates sit under Procurement Policy Note 06/21: Taking account of Carbon Reduction Plans in the procurement of major government contracts.
The “Minimum Viable” Structure – What Your Carbon Reduction Plan Must Cover
For procurement‑aligned Carbon Reduction Plans, official guidance sets expectations for:
- Commitment to Net Zero (by 2050 at the latest, within the UK context)
- Baseline emissions (what you are measuring progress against)
- Current year emissions for Scope 1 and Scope 2, plus a required subset of Scope 3 categories
- Carbon reduction measures already taken and planned (past / current / future)
- Declaration and sign‑off at director (or equivalent) level
- Publication on your UK website, with regular updates.
The required subset of Scope 3
Alongside direct energy use (Scope 1 and 2), Carbon Reduction Plans also include a set of indirect emissions known as Scope 3. These cover activities that sit outside day‑to‑day operations but are still linked to how the organisation works.
For most small organisations, this focuses on a limited, defined subset, such as staff commuting, business travel, waste, and the transport or distribution of goods and services. These categories are included because they are common to most organisations and can usually be estimated using information that is already available.
Practical point from our energy consultants for small organisations: Many organisations start by reporting the required Scope 3 categories using the best information available, then improve data quality over time as systems and supplier data develop. Where information is not yet complete, it helps to explain this clearly and indicate when updates are expected, rather than leaving sections blank. This approach keeps reporting transparent and avoids unnecessary follow‑up, while allowing Scope 3 reporting to mature at a manageable pace.
Step‑by‑step: a Practical Sequence for Small Businesses
Step 1 – Choose a reporting period you can repeat annually
Use a consistent 12‑month period across Scope 1, 2 and 3 so your results are comparable year on year.
Our energy consultant’s practical tip: many small organisations align the Carbon Reduction Reporting year to their financial year for ease of repeatable reporting.
Step 2 – Set organisational boundaries (keep it simple and explain it)
Organisational boundaries define which parts of your organisation are included in your carbon reporting. In simple terms, they set out what you are responsible for measuring and what sits outside your scope.
The GHG Protocol sets out three recognised ways of defining these boundaries:
- Equity share – reporting emissions in proportion to your ownership share;
- Financial control – reporting emissions from activities you financially control; and
- Operational control – reporting emissions from activities you operate and manage day to day.
For most small organisations, this comes down to choosing the approach that best reflects how the organisation actually runs – for example, whether you operate sites, vehicles or services directly, or whether they are controlled by another party.
What matters most is being clear and consistent. Once an approach is chosen, it should be applied the same way each year and explained in plain language. This helps ensure emissions are not double‑counted or overlooked, and allows progress to be tracked meaningfully over time.
Step 3 Gather the data using records you already have
For most small organisations, the quickest path is to build from existing operational records:
- Scope 1 (direct fuels): fuel invoices/receipts, generator fuel, fleet fuel cards (if applicable)
- Scope 2 (purchased energy): electricity/gas bills, landlord or facilities statements where energy is shared
- Scope 3 (required subset):
- business travel: travel booking records, expenses, mileage logs
- commuting/teleworking: a simple staff travel survey and basic homeworking assumptions
- waste: waste contractor invoices and waste transfer notes
- transport/distribution: courier invoices, delivery schedules, logistics supplier summaries.
For further information on emission scopes see our guidance: Scope 1, 2 and 3 Emissions Explained.
Step 4 Convert activity data into emissions using recognised conversion factors
To report emissions in tonnes of CO₂e, official guidance points to using government greenhouse gas conversion factors. The Department for Energy Security and Net Zero publishes annual conversion factors, with a condensed set recommended for most users.
What does CO₂e mean?
CO₂e stands for carbon dioxide equivalent. It is a standard unit used to express the climate impact of all greenhouse gases as a single, comparable figure, based on the amount of carbon dioxide (CO₂) that would cause the same level of warming.
Step 5 – Set targets and describe measures (past, current, future)
It is helpful to present carbon reduction measures in a simple, structured way that shows how activity is progressing over time. This can include:
- actions that have already been implemented,
- initiatives that are currently underway, and
- planned measures with indicative timelines.
This approach makes it easier for stakeholders to understand what has been done, what is in progress, and how future reductions are expected to be delivered, without the need for detailed or complex reporting.
Use a mix of absolute targets (reducing total emissions from your baseline) and intensity targets (such as emissions per £m of revenue or per unit delivered) can provide flexibility as the organisation grows, while still demonstrating progress.
Early progress often comes from short‑term, low‑disruption actions. This might include improving building controls, installing LED lighting where it is missing, consolidating deliveries, encouraging efficient driving, defaulting to rail for domestic travel where practical, or improving waste segregation.
Alongside this, it is useful to outline medium‑ and longer‑term plans, even where delivery will be incremental. This could include higher‑efficiency heating and cooling, heat pumps where feasible, on‑site solar generation, renewable electricity purchasing, or phased fleet replacement and charging strategies.
Where Scope 3 emissions are material, gradual supplier engagement can help improve both data quality and outcomes. Starting with suppliers linked to the largest emissions sources, simple requests for billed waste weights, transport distances and modes, or available emissions data can support steady improvement over time.
A short roadmap can bring this together. Showing indicative milestones over the next 12, 24 and 36 months, supported by light‑touch quarterly or six‑monthly check‑ins, makes it easier to track progress and feed results into each annual Carbon Reduction Plan update.
Our energy consultants top tip is – keep it proportionate: For small organisations, start with measures that are operationally realistic (energy efficiency, procurement choices, travel, commuting and waste practices) and build ambition over time.
Step 6 – Approval, declaration and sign‑off (don’t treat this as optional)
Your Carbon Reduction Plans should be approved by the board (or equivalent management body) and signed off by a director (or equivalent), including name, job title and date.
Step 7 – Publish it and update it annually
Making your Carbon Reduction Plan easy to find on your website helps customers, procurement teams and partners quickly understand your approach without repeated requests. Keeping previous versions available also provides a simple way to show progress over time, which can build confidence with stakeholders.
Where an organisation does not have a website, guidance allows for the plan to be shared on request, ensuring flexibility for smaller organisations.
Updating the Carbon Reduction Plan once a year, ideally within a few months of the financial year end, helps keep information current and avoids last‑minute work when requests arise. Regular, light‑touch reviews make carbon reporting more manageable and proportionate, rather than something that becomes a one‑off or reactive task.
If you need support producing a procurement‑aligned Carbon Reduction Plan, you can review what a Carbon Reduction Plan service typically covers and what information is required.
Common Reporting Issues for Small Businesses (and how to avoid them)
Inconsistent dates and boundaries
Small businesses often lose comparability by changing the reporting period or boundary approach year to year. Keep both consistent and explain any changes clearly.
Scope 3 information that may still be in progress
For small organisations, it is common for some Scope 3 information to take longer to collect, particularly where data sits with suppliers or employees. Where figures are not yet available, it is helpful to explain this clearly and indicate when the information is expected to be added.
Being open about what is still in progress creates clarity for customers and procurement teams, avoids unnecessary follow‑up questions, and demonstrates a structured approach to improving carbon data over time.
Making the Carbon Reduction Plan easy to find
Ensuring your Carbon Reduction Plan is easy to locate on your website helps reduce friction when customers, procurement teams or partners request it. Clear signposting saves time and prevents repeated requests for the same information.
For small organisations, this simple step can make engagement smoother and more consistent, particularly where carbon information is requested as part of tenders or supplier reviews.
