What Is a Carbon Reduction Consultant? A Complete Guide
Understanding your business's carbon emissions is an important part of making informed environmental decisions. Whether you're measuring your carbon footprint for the first time or exploring ways to reduce emissions, there are different approaches available to help you get started.
Some businesses choose to manage their carbon tracking independently, using software to collect information, calculate emissions and monitor their progress. Others prefer additional support from a carbon reduction consultant, particularly when working with multiple suppliers, reviewing complex data or developing a longer-term reduction plan.
Both approaches can be useful, and they don't have to be separate. Carbon tracking software can make emissions measurement more accessible, while consultants can provide specialist knowledge and practical support when it's needed.
So, what do carbon reduction consultants actually do, and does your business need one?
This guide explains their role, the services they provide, when expert support may be useful and how businesses can combine consultancy with carbon tracking software.
What Is a Carbon Reduction Consultant?
A carbon reduction consultant is a specialist who helps organisations measure and understand their greenhouse gas emissions, identify opportunities to reduce them and develop practical plans for taking action.
Their work can involve reviewing energy consumption, carrying out a carbon footprint assessment, examining business activities and recommending changes that may help an organisation reduce emissions over time.
Some consultants specialise in particular areas, such as energy efficiency, supply chains or carbon reporting. Others offer broader support across different parts of a business's operations.
The type of support needed often depends on where a business is in its carbon measurement process. An organisation starting from scratch might appreciate help identifying emissions sources and gathering information, while one with an established carbon footprint may want expert guidance on reviewing results and deciding what to prioritise next.
Importantly, businesses don't necessarily need a consultant to begin measuring their emissions. Carbon tracking software and accessible guidance can help organisations manage much of this work themselves, with specialist advice available where it adds value.
What Do Carbon Reduction Consultants Actually Do?
Carbon reduction consultants can support different stages of a business's carbon measurement and reduction planning process.
Although the services offered vary between providers, their work generally falls into five areas.
1. Assessing a Business's Carbon Footprint
A carbon footprint assessment involves identifying relevant greenhouse gas emissions sources and calculating emissions associated with an organisation's activities over a defined period.
This might include energy used in buildings, fuel consumed by company vehicles, business travel, purchased goods and services, or activities carried out by suppliers.
Under the GHG Protocol's greenhouse gas accounting standards, business emissions are commonly organised into three categories:
Scope 1: Direct emissions from sources owned or controlled by the business, such as fuel burned in company vehicles.
Scope 2: Indirect emissions from the generation of purchased electricity, heating, cooling or steam consumed by the business.
Scope 3: Other indirect emissions across the organisation's value chain, including relevant purchased goods, business travel and supplier activities.
A carbon consultant may help determine which emissions sources are relevant, review the information available and advise on appropriate calculation methods.
For a beginner-friendly explanation, read our guide to Scope 1, 2 and 3 carbon emissions.
2. Collecting and Reviewing Carbon Data
Measuring emissions involves bringing together information from different areas of a business. Some of this data may already be available in electricity bills, fuel records, supplier invoices, travel bookings and purchasing information.
A consultant can help identify which records are relevant, review existing calculations and work with internal teams or suppliers to gather additional information.
For example, an organisation might already have electricity bills and business travel records but need more detailed information about purchased products or supplier activities. A consultant could help establish what data is available and where an appropriate estimate may be needed.
Our guide to carbon data sources most businesses already have explains where useful information can often be found.
Where estimates are necessary, consultants can also help review the assumptions and methods used. Estimates can be useful in carbon accounting, provided their limitations are understood and recorded.
You can learn more in our article on whether businesses can estimate carbon emissions.
3. Identifying Opportunities to Reduce Emissions
Once a business understands where its emissions come from, a consultant can help identify areas where changes may be worthwhile.
These opportunities depend on the organisation's operations, facilities, suppliers and priorities.
For example, a consultant might review:
Energy consumption across offices, venues or other facilities.
Heating, cooling, lighting and equipment efficiency.
Transport and business travel arrangements.
Purchasing decisions and supplier information.
Operational processes that influence energy or resource use.
A business with several premises might explore building energy efficiency, while an organisation with extensive purchasing activities may focus on supplier engagement.
The aim is to identify practical opportunities based on the organisation's own emissions information, rather than applying the same recommendations to every business.
It's also important to distinguish identifying opportunities from achieving reductions. Changes need to be implemented and their results assessed before a business can confidently report that emissions have fallen.
4. Developing a Carbon Reduction Plan
A carbon reduction plan sets out how an organisation intends to address its greenhouse gas emissions over time.
It may include priority emissions sources, proposed actions, responsibilities, timescales and methods for monitoring progress.
A consultant can help assess different options and develop a plan that reflects the organisation's activities, resources and objectives.
An important starting point is understanding the business's existing emissions. This is often called a carbon baseline, which provides a reference point for comparing emissions over time.
Our guide to what a carbon baseline is and why it matters explains how businesses can use this information to support future planning.
5. Providing On-Site Support and Specialist Advice
Some organisations benefit from having a specialist visit their premises to understand how their operations work.
An on-site assessment may involve examining energy use, reviewing equipment, discussing operational processes or gathering more detailed information from suppliers.
For example, a business operating several buildings may want expert input on its energy consumption, while an event organiser might need help collecting information from venues, caterers, transport providers and production contractors.
This can be especially useful when supplier records or existing activity data don't provide enough detail to understand particular emissions sources.
For event organisers, our guide to tracking Scope 3 supply chain emissions for events explains why supplier information is an important part of event carbon measurement.
Which UK Carbon Reporting Requirements Can Consultants Help With?
Some carbon consultants also support businesses with emissions reporting and related regulatory requirements.
The rules that apply depend on the organisation's size, activities and circumstances. Not every UK business is required to report under the same frameworks, and hiring a consultant does not automatically guarantee compliance.
Here are some of the main requirements and standards businesses may come across.
Streamlined Energy and Carbon Reporting (SECR)
SECR requires certain UK organisations, including quoted companies and qualifying large unquoted companies and limited liability partnerships, to disclose energy use and greenhouse gas emissions information in their annual reporting.
A consultant may help an organisation gather relevant energy information, review emissions calculations and prepare supporting data.
You can find the official requirements in the GOV.UK environmental reporting guidelines.
We also explain the framework in our guide to SECR reporting requirements in the UK.
Energy Savings Opportunity Scheme (ESOS)
ESOS is a mandatory energy assessment scheme for qualifying large UK undertakings and corporate groups.
Organisations within its scope must complete an energy assessment every four years, covering relevant energy consumption across buildings, industrial processes and transport.
Consultants with the appropriate expertise may help businesses prepare for these assessments or identify opportunities to improve energy efficiency. Formal ESOS assessment requirements, including the role of an approved lead assessor, must still be met.
The GOV.UK ESOS guidance explains which organisations qualify and what they need to do.
Carbon Reduction Plans for Government Contracts (PPN 006)
Some businesses bidding for major UK central government contracts may need to provide a Carbon Reduction Plan as part of the procurement process.
Under Procurement Policy Note 006, this generally concerns relevant contracts valued above £5 million per year, including VAT, subject to the policy's scope and proportionality provisions.
A consultant may help a business prepare the emissions information and reduction planning needed for a relevant tender.
A formal procurement Carbon Reduction Plan has specific requirements and should not be confused with a voluntary internal reduction plan. The organisation remains responsible for meeting the applicable requirements.
UK Emissions Trading Scheme (UK ETS)
The UK ETS applies to specified regulated activities and operators, including parts of energy-intensive industry, power generation and aviation.
Organisations covered by the scheme have particular emissions monitoring, reporting and allowance obligations.
Specialist consultants may support these activities, although UK ETS work can require expertise and formal verification arrangements beyond general carbon footprint consultancy.
The government provides guidance on participating in the UK ETS.
GHG Protocol and ISO 14064-1
Alongside legal requirements, businesses may use recognised standards to guide how they measure and report greenhouse gas emissions.
The GHG Protocol provides widely used standards for corporate greenhouse gas accounting, including Scope 1, 2 and 3 emissions.
ISO 14064-1 provides requirements and guidance for quantifying and reporting greenhouse gas emissions and removals at the organisational level.
A consultant may help a business understand which methodology is appropriate for its circumstances. However, following a standard is not the same as receiving independent verification or certification.
How Much Does a Carbon Reduction Consultant Cost?
The cost of carbon consultancy varies depending on the organisation and the support required.
For example, a business looking for a one-off review of an existing carbon footprint may have different requirements from an organisation needing assistance across several premises, multiple suppliers and a detailed reduction plan.
Factors that can influence the cost include:
The size and complexity of the organisation.
The number of sites or activities being assessed.
Whether Scope 3 supplier data needs to be collected.
The quality and availability of existing information.
Whether on-site visits or specialist assessments are required.
The type of report, review or reduction plan being requested.
Some consultants offer fixed-fee services for clearly defined projects, while others provide tailored quotations or ongoing support.
When comparing options, it's useful to check exactly what is included, such as data collection, emissions calculations, reporting, expert review or reduction planning.
Businesses may also find that carbon tracking software provides a suitable way to manage their emissions independently, without needing to commission consultancy for every stage.
Do You Need a Carbon Reduction Consultant?
Not every business needs to hire a carbon reduction consultant to measure and track its emissions.
For many organisations, carbon tracking software provides a practical starting point. Businesses can gather information, calculate emissions and develop a clearer understanding of their carbon footprint without outsourcing the entire process.
The right approach depends on the organisation's activities, the information available and the time or expertise of the people managing the work.
For example, a small office-based business may already have access to the electricity, heating and travel records needed to begin measuring several important emissions sources.
A larger organisation with multiple sites, extensive supplier relationships or specialist reporting requirements may appreciate additional guidance.
Consultancy can also be useful when a business has already measured its emissions but wants expert support interpreting the results and identifying potential next steps.
Rather than viewing consultancy as something every business must have, it's more helpful to think about which parts of carbon measurement and reduction planning your organisation would benefit from managing independently and where specialist input could add value.
Carbon Reduction Consultants vs Carbon Tracking Software: What's the Difference?
Carbon tracking software and consultancy serve different purposes, although they can work together.
Carbon tracking software helps businesses organise activity data, calculate emissions using relevant methodologies and monitor their carbon footprint over time.
Consultants provide specialist expertise, which may include reviewing information, advising on data collection, investigating operational activities and developing reduction plans.
Activity | Carbon tracking software | Carbon reduction consultant |
Organising emissions data | Helps structure and manage information | Can advise on what information to collect |
Calculating emissions | Supports calculations using relevant methods | Can review assumptions, methods and results |
Working with suppliers | May support organising supplier data | Can liaise with suppliers and investigate information gaps |
Monitoring emissions | Supports tracking over time | Can help interpret changes and identify priorities |
Developing reduction plans | Can provide useful emissions information | Can assess options and help develop a tailored plan |
On-site assessments | Does not replace physical investigation | Can examine facilities and operational activities directly |
The exact capabilities of software and consultancy services vary between providers.
For businesses comfortable managing their own carbon data, software may provide the support they need. For organisations wanting additional expertise, consultancy can help with specific tasks while the software continues to support ongoing measurement.
When Might Carbon Consultancy Be Useful?
There are several situations where businesses may decide that additional expert support would be worthwhile.
When You Don't Have a Dedicated Sustainability Team
Many organisations manage environmental responsibilities alongside other day-to-day business activities.
If collecting emissions data is taking time away from other priorities, a consultant or specialist support team may be able to help gather information, contact suppliers and organise the records needed for measurement.
When Your Supplier Data Is Complicated
Supplier-related emissions can involve information held by several different organisations.
An event organiser, for example, may need data from its venue, catering suppliers, transport providers and production contractors. A consultant can help establish which information is needed and work with suppliers to improve the available data.
When You Want an Expert Review
Businesses that have already calculated their carbon footprint may want a specialist to review the information, assumptions and methodology used.
This can be helpful when improving data quality, reviewing estimates or preparing information for stakeholders.
Expert review is not automatically the same as independent carbon footprint verification or formal assurance. Those services have separate requirements, so businesses should check exactly what type of review is being provided.
For more guidance, explore our article on how to improve your carbon data over time.
When You're Ready to Develop a Reduction Plan
Measuring emissions helps businesses understand which activities contribute to their carbon footprint.
A consultant can help use that information to explore possible actions, identify priorities and develop a practical reduction plan.
Some consultants may also advise on carbon credits or offsetting as part of a wider environmental strategy. However, purchasing carbon credits is different from reducing emissions within a business's own operations and value chain.
Claims about carbon neutrality or net zero require appropriate evidence and should not be based simply on purchasing offsets.
Our guide to carbon neutral vs net zero explains the distinction.
How Scope Combines Carbon Tracking Software With Optional Consultancy
At Scope Carbon Tracking, we aim to make measuring and understanding carbon emissions more accessible for businesses and event teams.
Our carbon tracking software is designed to help organisations manage their emissions information independently, without necessarily needing a consultant.
For those who would benefit from additional support, Scope also offers carbon consultancy services.
This can include help gathering information from suppliers, reviewing emissions data, developing a carbon reduction plan or arranging specialist on-site support where appropriate.
The aim is to give organisations flexibility. Some may choose to manage their carbon tracking themselves, while others may want help with a particular stage of the process.
Consultancy is an option, not a requirement for using Scope. Businesses can use the software independently and explore additional support if their needs change.
How to Choose the Right Carbon Reduction Support for Your Business
If you're considering working with a consultant, it's worth thinking about what you want to achieve and which parts of the process you'd like help with.
Some useful questions include:
Are we measuring our carbon footprint for the first time, or do we already have emissions data?
Do we have the time and resources to collect information internally?
Are there particular suppliers or activities we need help understanding?
Would an expert review of our calculations be useful?
Do we want support developing a carbon reduction plan?
Do we need on-site expertise, or would remote support be sufficient?
How will we continue tracking emissions after the consultancy work is complete?
You can also ask prospective consultants about their experience, the methodologies they use, the information they will need and what their services include.
If independent verification or assurance is required, check whether that specific service is available and whether the provider has the necessary independence and credentials.
Choosing the right support is about finding an approach that fits your organisation, whether that's software, consultancy or a combination of both.
Getting Started With Carbon Measurement and Reduction Planning
Carbon reduction consultants can provide useful expertise, from reviewing emissions data and working with suppliers to identifying reduction opportunities and developing practical plans.
However, consultancy isn't the only way to begin understanding your carbon footprint.
Businesses can start by identifying their main emissions sources, gathering the information they already have and using carbon tracking software to organise and measure their emissions.
As their understanding develops, they can decide whether additional specialist support would help with particular activities or future plans.
With Scope, businesses have the flexibility to take either approach. Our software supports independent carbon tracking, while optional consultancy provides additional expertise when it's useful.
