Begin by educating yourself and your team about the concepts of carbon accounting and footprinting. Understand the different scopes of emissions (Scope 1, Scope 2 and Scope 3), emission factors and global warming potentials.
Define your goals for carbon accounting. Are you aiming to reduce emissions, achieve carbon neutrality, or meet regulatory requirements? Determine the scope of your analysis, including which emissions sources you will include (eg: direct emissions, energy consumption, supply chain emissions).
Collect relevant data for each emissions source within your chosen scope. This could include energy consumption, fuel use, transportation, production processes and more. Data collection might involve analysing invoices, utility bills and operational records.
Identify appropriate emission factors for your activities. Emission factors provide the conversion rate of activity data (e.g., fuel consumption) to CO2 equivalent emissions. These factors are often provided by environmental agencies or industry associations.
Use the collected data and emission factors to calculate your organisation's emissions for each relevant source. This might involve spreadsheet calculations or specialised software.
Consider using specialised carbon accounting software or online tools. These platforms streamline data collection, calculations and reporting.
If your organisation lacks expertise in carbon accounting, consider hiring consultants or experts who specialise in sustainability and emissions analysis. They can guide you through the process and ensure accurate calculations.
Depending on your goals and stakeholders, you might choose to verify your emissions data through third-party audits. This adds credibility to your reported emissions and sustainability efforts.
Analyse the emissions data to identify high-impact areas and develop strategies for emissions reduction. These strategies might include energy efficiency improvements, renewable energy adoption and supply chain optimisation.
Carbon accounting is an ongoing process. Regularly monitor your emissions and track progress toward your goals. This allows you to adjust strategies if needed and demonstrate continuous improvement.
Communicate your emissions data and reduction efforts transparently to stakeholders. This could include sustainability reports, disclosures to investors and for large companies, participation in carbon reporting initiatives like the Carbon Disclosure Project (CDP).
Involve your employees in the carbon accounting process. Raise awareness about sustainability and encourage employees to contribute to emissions reduction efforts within their roles.
For Scope 3 emissions, work with your suppliers to gather data and collaborate on emission reduction strategies. Supply chain engagement can have a significant impact on your overall footprint.

Businesses can access carbon accounting and footprinting through a combination of internal efforts, external services and specialised tools.

Remember that the process might vary based on the size of your business, industry and specific goals. Whether you choose to handle carbon accounting internally or seek external assistance, the key is to start by understanding your emissions sources, collecting accurate data and gradually implementing reduction strategies. Over time, carbon accounting can become an integral part of your organisation’s sustainability practices.
