"Eddie and the C Free team have been excellent to work with over the last year. They have provided invaluable help as we continue our carbon tracking journey. C Free has been a great partner to help us and has demonstrated a clear commitment to continue to iterate and improve their collection methods using feedback. They have been brilliant at creating a genuine transformational rather than a transactional relationship which we look forward to continuing as we further track, report and lower our environmental impact."

FAQ

When we calculate your carbon footprint we take a deep dive into your business operations to ensure that we get as accurate an impression of your emissions as possible. Every business is different which means that every calculation is different. This does make it difficult for us to put a standard price on our service without speaking with you first. Our carbon footprint calculations and GHG reports start at £2,500 and this increases with complexity and size of the business. We do have different packages depending on your needs so its worth booking a call and, after a brief chat, we can put together a proposal.

This is one of those “How long is a piece of string?" questions. But let me give you some numbers so you can get an idea. The time taken is split into two main parts: Data Collection - that involves you, the client, and the calculation and report writeup - that is on us, C Free. In terms of data collection, this can take anywhere between a week and 6 months. We have been working hard on improving client data collection so that it takes less and less time, with some of our clients returning everything we need in a matter of days. To be safe 1-2 months is usually a sensible timeframe for collecting the data. We contractually oblige ourselves to complete the calculation and return the reports, dashboard, and presentation within 60 days of receiving all of the data we need. Often this is significantly less with our average time being 30 days. We have been known to turn this around in a week, but do not recommend this unless there is a deadline that has to be hit and is agreed upon before starting the work. With this in mind, you can be confident you will have a full calculation and report in around 2-3 months, as long as you are engaged with the process and don't let it slip down the priority list.

CCF - otherwise known as a Corporate Carbon Footprint or a calculation of your business includes measuring emissions across scope 1, 2 and 3 emissions. This is the type of calculation that you need to complete for a Carbon Reduction Plan, for sustainability questionnaires, and for assessments like B Corp. The idea here is to get a picture of all of the emissions that are related to your business. PCF - A Product Carbon Footprint (PCF) specifically targets the emissions associated with the lifecycle of an individual product—from the extraction of raw materials to manufacturing, distribution, use, and end-of-life disposal. A PCF is crucial for businesses looking to assess the environmental impact of specific products, helping to make informed decisions on product design, sourcing, and end-of-life strategies. It’s often a component of detailed product labeling and can demonstrate to clients and consumers the commitment to reducing carbon impact on a per-product basis. LCA - Life Cycle Assessment (LCA) is a comprehensive methodology that goes beyond just carbon emissions, evaluating a broad spectrum of environmental impacts (such as water use, resource depletion, and pollution) throughout a product’s life. It assesses each stage of the product’s life cycle in-depth, from raw material extraction, production, and transportation to use, and disposal. LCAs provide a more holistic view than PCFs, helping businesses understand and mitigate various environmental impacts, often to meet regulatory standards or to improve overall sustainability performance across multiple indicators beyond carbon alone.

PPN 06/21 is a UK government procurement policy that requires suppliers bidding for large government contracts to produce a Carbon Reduction Plan (CRP). The CRP must detail your current carbon emissions, outline your commitment to achieving net zero by 2050 at the latest, and demonstrate your efforts to reduce emissions. C Free helps you create a compliant CRP, ensuring that your business meets the necessary requirements for public sector tenders.

As part of our service to NHS suppliers, we will sit on a call with you and run through answering the Evergreen assessment questions. We specialise in carbon accounting so we can only assist with the carbon-related questions. There are other aspects of the Evergreen Assessment that you will need to complete such as a modern slavery statement.

The GHG (Greenhouse Gas) Protocol is the most widely used international accounting standard for measuring and managing greenhouse gas emissions. It categorises emissions into three scopes: Scope 1 (direct emissions), Scope 2 (indirect emissions from purchased energy), and Scope 3 (all other indirect emissions in your value chain). At C Free, we use the GHG Protocol as our methodology to accurately calculate your emissions across all relevant scopes, ensuring your carbon reporting is comprehensive and aligned with global standards.

Absolutely. Our primary service will produce a draft Carbon Reduction Plan compliant with the regulations for you to sign off and submit. A CRP is a declaration made by you the company, so it will need to be signed, made into a pdf and made publicly available by uploading to your website.

Certainly. We have supported clients with the carbon aspects of their B Corp applications. Check out this case study for an example.

Our calculations are absolutely compliant with SBTi requirements. Furthermore, we are more than happy to assist with the application process. We can be on call with you as you go through the submission to answer any questions and make sure it goes smoothly.

Carbon accounting is a bit like financial accounting in the way that there are SaaS carbon accounting softwares in the same way there are financial accounting softwares. The difference is that it’s quite tricky to use carbon accounting software and you really need to have some internal expertise to do so. What data do you need? Where do you get the data? How do you know which scope an emission should be in? How do you know which category it should be in? What emission factor has been used? C Free is a tech-enabled consultancy that has built up our own internal software to make data collection easy for our clients. We also make sure that everything is covered and help you find the data we need. In financial accounting terms, we're the software, bookkeeper, and management accountant.

Primarily, we follow the greenhouse gas protocol. However, we are familiar with all the major standards and adjust our approach to fit with the particular requirements of the given regulatory framework or requirements. For more info on our standard approach, check out our methodology document here.

The Carbon Accounting Alliance (CAA) is a global network of organisations, professionals, and experts dedicated to advancing carbon accounting practices. It fosters collaboration, shares best practices, and drives innovation in carbon measurement and management. As members of the CAA, C Free stays at the forefront of industry standards, ensuring our calculations are accurate, reliable, and up-to-date with the latest methodologies in carbon accounting.

We follow the GHG-protocol - the most globally renowned calculation standard - and have open sourced our methodology for public scrutiny. Furthermore, we have an extensive test suite that rigorously evaluates the performance of our calculations against industry standards. But beyond that, along with our calculation we report the uncertainty of our calculations. By conducting a Monte Carlo simulation, we can calculate the error on your footprint so that you can make informed decisions. You can read more about that here.

This depends on the data quality you have in house. If you keep good records of your business activity, this can be as simple as downloading a few spreadsheets and answering a survey. However, for many businesses, there is some work required to retrieve relevant data sets; typically a company will assign one person and it will take them, in total, a matter of hours to gather all relevant information.

First and foremost, we deliver whatever you need. One of our greatest strengths is our flexibility so we can deliver what you need for your project. However, in additional to your specific requirements, we will always deliver a GHG-protocol compliant report, detailing our calculation. this can be handed on to stakeholders who are interested in the details of your calculation. We can also produce a PPN 06/21 compliant carbon reduction plan and complete the sustainability sections of any tender applications you require. We also deliver a carbon dashboard. This is the hub of your emissions report delivering interactive access to various features of your footprint. Checkout this link to see an example.

Calculating your emissions is the essential first step in tackling them effectively. Without a clear picture of your carbon footprint, it’s nearly impossible to set meaningful reduction targets or track progress. By measuring emissions, you gain insights into high-impact areas where changes can make the biggest difference, enabling more strategic, data-driven decisions. Beyond internal benefits, a robust emissions calculation is often essential for meeting regulatory requirements, applying for tenders, and completing sustainability assessments like Carbon Reduction Plans. It’s also a critical part of making credible commitments toward going net zero or achieving carbon neutrality, showing clients, partners, and stakeholders that your business is serious about sustainability. In short, it positions your business as a responsible, forward-thinking leader in a market that increasingly values environmental impact and regulatory compliance.

Firstly we ask for expenses data. With this, we make a map of your company activity that will help us calculate your footprint. After categorising your expenses, we may ask for further data in selected areas depending on the kinds of activities your company does and the quality of the data in your expenses. This can be anything from energy bills and fuel cards to asset registers and travel data.

This depends on what you are calculating. Business calculations, much like financial accounts, should be recalculated every year to track progress towards your goals. However, PCFs/ LCAs need only be updated when there is a significant change in production or the supply chain.

We can help all companies with their carbon needs. However, we have particular expertise in helping companies meet regulatory requirements such as CSRD, PPN 06/21, and the Evergreen Assessment.

We keep all relevant data on our servers end and can setup any kind of data connection to your business systems you require.

The Corporate Sustainability Reporting Directive (CSRD) is a European Union regulation that mandates comprehensive sustainability reporting for a wider range of companies than previously required under the Non-Financial Reporting Directive (NFRD). Starting from 2024, it requires qualifying businesses to report on their environmental, social, and governance (ESG) impacts, with a strong emphasis on transparency in carbon emissions, sustainability efforts, and social responsibility. CSRD is intended to standardise ESG reporting across the EU, making it easier for investors and stakeholders to assess a company’s sustainability performance and compare it to industry peers. One part of CSRD is carbon reporting - we can help with this bit!
