Carbon accounting is a set of methods that measure how much greenhouse gas (GHG) an organization emits. It calculates emissions as a measure of carbon dioxide equivalent (CO2e) units, as a simple way to express the combined impact of CO2 and other greenhouse gases.
Carbon accounting helps organizations quantify the environmental impact of their activities. They can then use this data to identify opportunities for emission reduction across the value chain, thereby staying compliant with environmental regulations and doing their part to combat climate change.
Carbon accounting software enables a streamlined, data-backed approach to carbon accounting for organizations. Below are the carbon accounting platforms based on their advanced AI capabilities, sustainability management, and compliance with global standards.

What Is Carbon Accounting?
Carbon accounting is the systematic process of identifying and quantifying greenhouse gas emissions from an organization’s activities. Done correctly, carbon accounting helps organizations see exactly what their climate impact looks like, and thus be more intentional about resource usage and decarbonization.
Carbon accounting classifies GHG-emitting activities into three categories, known as scopes. In descending order of priority, they are as given below.
- Scope 1 — Direct emissions from fossil fuel burning activities that are directly under the organization’s control, such as manufacturing equipment that runs on diesel.
- Scope 2 — Indirect emissions from the energy purchased by an organization, such as electricity from a power plant.
- Scope 3 — Indirect emissions from the organization’s other purchases (such as leased commercial space or employee commuting) and external activities (such as the use or disposal of its sold products).
What Is Carbon Accounting Software?
Carbon accounting software is a platform designed to help companies track, measure, and manage their carbon footprint across business activities. By automating data collection and analysis, carbon accounting solutions help companies measure their GHG emissions precisely, identify emissions hotspots, take informed decisions to improve efficiency, and stay compliant with environmental standards.
What Are the Benefits of Carbon Accounting Software?
Carbon accounting software helps companies reduce costs, launch emissions reduction schemes, and enhance brand goodwill. Some benefits of carbon accounting software are given below.
- Automated Data Collection — The best carbon accounting platforms have a unified workflow that automatically collects data across multiple emissions sources.
- Streamlined Calculations — Carbon accounting platforms are powered by algorithms that match emissions data with a standardized set of factors to prepare accurate, easy-to-interpret results.
- Centralized Data Management — With carbon accounting tools, businesses can see exactly what their emissions patterns look like through a customizable dashboard.
- Improved Decision-Making — By quantifying the climate impact of their activities, carbon accounting platforms can help organizations identify and prioritize emissions reduction opportunities along their value chain. They can then set reduction goals and track their progress systematically.
- Compliance with Regulations and Standards — Around the world, regulators are requiring that businesses disclose their carbon emissions as per local standards. Carbon accounting software prepares standardized reports with all relevant data, helping businesses stay compliant.
- Demonstrate Environmental Commitment — Today, 77% of consumers believe it is important for a brand to have sustainable practices[1]. With carbon accounting software, businesses can start actioning carbon reduction initiatives and thus demonstrate their commitment to fighting climate change.
- Attract Green Investment — Businesses that have a structured approach to reducing emissions are much likelier to attract green investment, allowing them to further expand their carbon reduction initiatives.
What Are the Different Carbon Accounting Methods?
Below are tried-and-tested techniques employed by leading carbon accounting tools, especially to incorporate the full scope of carbon emissions from indirect Scope 2 and Scope 3 sources.
- Physical-unit method — This is one of the most popular carbon accounting methods. It involves measuring the number of physical units of the organization’s emission-generating activities, such as liters of gasoline burned or kWh of electricity used.
- Spend-based method — This method of carbon accounting multiplies the financial value of a purchased product with the associated emissions factor, measured as the quantity of GHG emissions per currency unit.
- Supplier-specific method — This involves collecting end-to-end GHG inventory data for each product from its supplier. It offers the highest degree of reporting accuracy, especially for Scope 3 emissions.
- Average-data method — This method approximates emissions by compiling data about resources consumed and activities undertaken and then applying secondary emission factors, like industry averages.
- Hybrid method — This method combines supplier-specific data with secondary data. It’s a flexible method that can be adapted to different levels of data quality and availability.
