What is Carbon Accounting Software?
Carbon accounting software helps businesses measure, monitor, and manage their greenhouse gas emissions. With it, companies can collect accurate emissions data and begin planning meaningful strategies to reduce, or eventually eliminate, their carbon footprint through decarbonization.
These platforms are typically built around the Greenhouse Gas Protocol (GHGP), which serves as the global standard for emissions tracking. Although referred to as “carbon” accounting, the term broadly includes various greenhouse gases, such as:
- Methane
- Nitrous oxide
- Hydrofluorocarbons
- Perfluorochemicals
- Sulfur hexafluoride
- And other related gases
In the Philippines, the Securities and Exchange Commission (SEC) has rolled out ESG reporting guidelines for publicly listed companies, aligning with global ESG frameworks.
As pressure for transparency grows, many Filipino businesses are turning to software solutions to simplify emissions tracking and prepare for future climate-related disclosures.

Key Features in Carbon Accounting Software
When evaluating carbon accounting solutions, businesses should focus on these 6 essential capabilities:
1. User-friendly and robust data input tools
Reliable carbon accounting starts with clean, complete data. Look for platforms that support manual entry, bulk uploads, and API integrations to streamline data collection, so organizations can fine-tune their ESG strategy.
2. Automated and accurate carbon footprint calculations
A strong solution should automatically calculate your company’s emissions across Scope 1, 2, and 3. These calculations form the foundation for compliance, reporting, and setting realistic reduction goals.
3. Comprehensive emissions reporting
Choose software that supports detailed GHG reporting, both for compliance and voluntary disclosure. Flexible export options—such as publish-ready PDFs and raw data files—are essential for internal and external use.
4. Decarbonisation target setting and tracking
Effective tools should help you define, visualise, and monitor emissions reduction targets using recognized methodologies like Science-Based Targets (SBTs). Interactive graphs and visualisations make progress easy to understand.
5. Real-time performance tracking and analytics
Advanced dashboards allow teams to track emissions and net-zero efforts continuously. Built-in analytics turn raw data into actionable insights, supporting smarter and faster sustainability decisions.
6. Actionable decarbonisation planning tools
The software should identify high-impact reduction opportunities and incorporate Scope 3 data for a full-supply-chain approach. Features that help manage emissions projects make implementation smoother and more scalable.
Using Dedicated Carbon Accounting Tools vs. Building Internal Solution
While the growing adoption of carbon accounting is a big step forward in addressing the climate crisis, actually measuring emissions isn’t simple. It requires structured data, clear methodology, and alignment with global frameworks.
So the question becomes: should your business build its own carbon accounting solution or use dedicated software?
Building a custom system in-house may seem appealing if you want full control or already have internal tools in place. But in reality, this approach demands significant time, technical resources, and deep sustainability expertise.
For most companies—especially those without a large ESG team—creating, maintaining, and validating a reliable system from scratch can become overwhelming fast.
On the other hand, using dedicated carbon accounting software gives you access to prebuilt emissions factors, automated data collection, and reporting tools aligned with international standards.
For small to mid-sized businesses, especially, dedicated software is often the smarter choice. It’s faster to implement, easier to manage, and allows your team to focus more on reducing emissions than manually calculating them.
How to Choose the Most Suitable Carbon Accounting Software
Selecting the right carbon accounting software starts with understanding your organisation’s unique requirements and sustainability objectives. It’s important to choose a platform that can accurately track and manage emissions based on your industry and operational scope.
Evaluate whether the software offers strong reporting functions, integrates easily with your existing systems, and is user-friendly. Also, ensure it complies with established frameworks such as the Greenhouse Gas Protocol or ISO 14064 for credible and consistent emissions reporting.

Carbon accounting software plays a critical role in helping businesses track emissions and meet sustainability standards efficiently. With the right tool, companies can automate reporting, set reduction targets, and align with global climate goals faster.
