A study found that 85% of organisations are concerned about reducing their greenhouse gas emissions, yet only 9% of companies are able to quantify their total emissions comprehensively (BCG).
Accordingly, carbon accounting measures and tracks the amount of CO2e an activity or entity emits. Modern companies use software to make this process easier, automated, more accurate, and more frequent, ensuring reliable data for sustainability reporting.

Essential features to look for in carbon accounting software
Here are 6 critical features businesses should prioritise when searching for a carbon accounting solution:
1. Intuitive and powerful data collection
To ensure accurate and efficient carbon accounting, interfaces for manual input, bulk imports, and API connections help maintain data hygiene and reduce errors.

Using a dedicated carbon management software versus building internal solutions
Internal solutions, often using multiple spreadsheets and scattered data, lack the expertise and accuracy needed for emissions analysis. A SAP survey found that only a third of mid-market executives are satisfied with their data quality, and 86% still use spreadsheets for emissions tracking.
Switching to carbon accounting software simplifies data collection, automates calculations, and improves accuracy. Read our 11 reasons why you should not use spreadsheets for carbon accounting in our dedicated article.
As a carbon accounting expert, I strongly advocate using sustainability software over internal solutions. Unlike cumbersome internal solutions reliant on spreadsheets, advanced software offers efficient data collection, accurate emissions calculations, streamlined data integration across departments, and enhanced stakeholder transparency. This allows for vast time and cost savings whilst strengthening brand resilience and mitigating risks related to compliance and sustainability commitments.

How to choose the best carbon accounting software for your company?
To ensure you choose a solution that aligns with your sustainability goals and operational needs, we recommend asking these 12 questions when evaluating carbon footprint software:
Companies looking to make a meaningful impact on the environment must choose a carbon accounting software aligned with GHG Protocol Methodology. GHG Protocol supplies the world's most widely used greenhouse gas accounting and is essential for ensuring accuracy and reliable carbon management. From an operational perspective - prioritising a platform that is easy to use, provides intuitive and data-driven insights, and has a team of real-world climate experts behind it is essential to setting your organisation up for sustainability success.

Examples of companies using carbon accounting software
Businesses around the globe are using software to overcome carbon accounting challenges and undergo sustainable transformation. Here's a few examples of companies who have seen exceptional results:
Ganni
Ganni faced difficulty in ensuring accurate emissions data, leading to misassumptions and resource inefficiencies. Plan A’s Carbon Management Platform enabled Ganni to seamlessly collect, store and measure emissions data, whilst identifying any gaps or areas for data improvement. This enables Ganni to realise a 7% absolute emissions reduction on their 2021 baseline (despite an 18% AAGR since 2021).
Furthermore, Ganni had difficulties in setting targets that are ambitious (yet achievable), and identifying initial levers for emissions reduction. Plan A’s Off-platform assistance to help Ganni establish reduction targets and identify reduction levers (prioritising effort based on high-impact areas, e.g. switching to low-carbon materials phasing out carbon-heavy materials like virgin leather). This has enabled Ganni to make 14% progress toward achieving their goal of 50% target kg CO2 reduction by 2027
AMPECO
AMPECO faced difficulty in streamlining data collection and entry, leading to time and resource inefficiencies.Plan A’s Carbon Management Platform enabled AMPECO to efficiently onboard their business activity data; enabling time savings of up to 80%. Petar Georgiev, Head of Sustainability at AMPECO notes that Plan A has allowed for a “significant” amount of time saved on data entry.
Furthermore, AMPECO previously faced difficulty in pinpointing areas for improvement and optimisation across their operations and wider value chain. Plan A’s all-in-one platform with customisable dashboards enabled AMPECO to intuitively analyse their emissions through visual charts to identify areas for improvement and drive decarbonisation progress (e.g. optimising cloud usage and running their platform more efficiently). Ultimately, this has enabled AMPECO to stay on-track toward an ambitious target of 50% Scope 1 & 2 emission reduction by 2025
All carbon accounting software providers in 2025
Businesses that do not take the lead on sustainability will ultimately be unable to remain competitive. Accordingly, companies must integrate carbon accounting software into their broader corporate strategy. Companies must look to source a comprehensive and user-friendly platform that is underpinned by data, decarbonisation-oriented, scalable, and able to be tested before purchasing.
What is a good carbon accounting software for EU companies?
Evolving regulations in the EU (e.g. the CSRD) mean companies are required to adopt robust carbon management systems to ensure compliance and meet growing stakeholder demands. Carbon accounting software enables companies to not only streamline carbon accounting, but also align with regulations, report in line with frameworks such as the Greenhouse Gas Protocol, and identify areas for emission reduction.
One standout option for EU companies is Plan A. Renowned for its comprehensive features, Plan A offers tailored solutions to navigate the complexities of carbon accounting and regulatory compliance thanks to the dedicated module "CSRD Manager". The software combines data collection, emissions tracking, and actionable insights to help companies reduce their carbon footprint with ease. Moreover, it supports seamless reporting, making it a highly reliable choice for businesses striving to prepare for EU sustainability regulations.
How much does carbon accounting software cost?
The cost of carbon accounting software usually ranges between €3,000 and €80,000+ per year. However, this range can vary significantly based on factors such as company size, industry, the complexity of operations, and the level of customisation required. For instance, a multinational corporation with multiple facilities may incur higher costs due to the need for advanced data integrations and industry-specific analytics.
It’s essential to recognise that the cost of the software is only part of the equation. Choosing a robust platform like Plan A offers added extensive value beyond carbon tracking. Advanced features, such as ROI of decarbonisation tools and cost-saving calculators, help companies identify financially viable emission reduction opportunities. These tools not only enhance sustainability but also improve overall profitability.
