10 Best Carbon Accounting Software of 2023 (Ranked)

10 Best Carbon Accounting Software of 2023 (Ranked)

The terms business accounting software and enterprise resource planning (ERP) software are often used interchangeably, but they refer to two different types of tools.

Most recently, carbon accounting started coming to mind when the two above terms were being talked about, as more and more companies are trying to be proactive in monitoring and reporting their greenhouse gas (GHG) emissions.

With most companies being more aware of their environmental impact, it has become increasingly important to have a way to manage and report on carbon emissions.

Doing so can help companies set goals for reducing emissions, track progress, and make informed decisions about how to operate more sustainably.

More companies are attempting to reach a net-zero emission, where they offset their carbon footprint entirely.

That said, reaching a net-zero emissions goal requires strategic planning by the various companies.

In this article, I will go through the best carbon accounting software and highlight its features, so you can decide which software fits your company best.

Let’s get right into it.

What Is Carbon Accounting Software?

Carbon accounting software works to help organizations quantify and manage all aspects of their carbon reduction efforts.

With the proper carbon management tools, companies can streamline their intel collection process and draw insights to make better data-driven decisions.

Yet, the carbon accounting software industry is still in its infancy.

For that reason, it’s important to note that “carbon” is used as an umbrella term for several types of greenhouse gases.

As outlined by the Greenhouse Gas Protocol, this includes:

  • Methane
  • Perfluorochemicals
  • Sulfur
  • Hexafluoride
  • Hydrofluorocarbons
  • Nitrous oxide

Companies that do the work to integrate carbon accounting software into their broader approach to carbon management are better equipped to manage compliance concerns and stakeholder expectations.

Both of these are critical to a company’s public reputation.

Those embracing audit-grade carbon accounting software are better prepared to communicate their CO2 footprints to critical stakeholders and manage compliance concerns.

Yet price-conscious SMEs can consider Sweep as a possible solution that comes with its tradeoffs.

Features To Look For In Carbon Accounting Software

Now, the question is: Which features should you look for in carbon accounting software and why?

It’s important to note that companies are ultimately looking for manageable ways to handle their carbon footprint responsibly and adequately comply with emissions legislation.

Due to regulations changing from region to region, a carbon accounting tool that’s flexible enough to cover those needs—often at scale—is critical.

As you go through vetting your best carbon accounting systems, consider the following pointers to make an informed choice.

Data unification

How tamper-resistant the data collection process is and what automation features you can use to keep up with the data collection process are all important.

The more accurate data you can centralize, the easier time a company has drawing insights and creating accurate reports.

Industry track record

It’s not enough to know what features a carbon accounting tool offers.

Its industry track record also matters.

Asking yourself questions such as the following is key:

  • Who are the founders?
  • What history do they have in the emissions industry?
  • What are their relevant partnerships, and how are they leveraged?

The more you can learn about the background of an emissions solution and how it came to be, the better-rounded your understanding of what the solution is capable of once implemented.

Robust emissions reporting and analytics

The need for accessible reporting and analytics features can’t be stressed enough.

Carbon accounting software is designed to help you ditch the time-consuming process of managing data in siloes or through manual processes.

When vetting your options, understand what value you can reap from its reporting and analytics capabilities.

The more automation options you have to configure a reporting and analytics workflow, the better.

Best Carbon Accounting Software – FAQ

What Does A Carbon Accounting Software Platform Do?

A carbon accounting software platform helps organizations track and manage all aspects of their carbon emissions.

Carbon reporting helps organizations to:

  • Understand their total carbon footprint
  • Benchmark performance against industry peers
  • Set goals for reducing emissions
  • Manage and monitor progress towards those goals
  • Through emissions reports, communicate their emissions data and sustainability efforts to key stakeholders

With frameworks like the GHG Protocol in place, more businesses realize the importance of accurate carbon sustainability data regarding GHG emissions.

This type of management software can help businesses stay compliant with emissions regulations and improve their overall sustainability practices.

What Methodologies Can Offset Carbon Accounting Software Platforms Use?

The Greenhouse Gas Protocol (GHG Protocol) is the most common carbon accounting methodology.

The GHG Protocol provides a comprehensive approach to measuring and managing carbon emissions and reducing GHG emissions.

ESG reporting is another framework that businesses can use to measure and report on their environmental, social, and governance metrics.

The value chain or life cycle assessment (LCA) is another popular approach that businesses use to understand and manage their impact on the environment.

Carbon offsets can be used to help businesses offset their emissions.

Carbon offsets can be purchased from carbon offset projects, which help reduce greenhouse gas emissions in the atmosphere.

Organizations can use carbon accounting software platforms to track and manage their purchases of offsets, as well as report on their progress towards offsetting their emissions.

Why Is Climate Action Needed?

The environmental impact of human activities on the planet has been well documented.

A software platform that can help organizations track and manage their emissions is a critical part of mitigating the impact of climate change.

Organizations that can effectively manage their emissions can reduce their environmental impact and improve their bottom line.

What Does Carbon Neutral Mean?

Carbon neutrality is the goal of reducing net greenhouse gas emissions to zero.

A carbon-neutral organization would have no net emissions, meaning that carbon reduction measures would offset any emissions they produce.

Carbon footprint measures the total amount of greenhouse gases emitted by an individual, product, event, or company.

What Are The Emissions Factors That Carbon Accounting Software Platforms Use?

Emissions factors are data that quantify the emissions from a given activity.

Emissions factors can be expressed in weight, volume, or distance traveled.

The ability to track emissions and understand emissions factors is critical for businesses that want to manage and reduce their impact on the environment.

Renewable energy credits (RECs) are a type of carbon offset that can be used to offset emissions.

RECs are credits generated from the production of renewable energy, such as solar or wind power.

Organizations can use RECs to offset their emissions and report on their progress towards offsetting their emissions.

What Is Decarbonzation?

Decarbonization is the process of reducing an organization’s or individual’s carbon footprint.

It can be achieved through various means, such as investing in renewable energy, switching to low-carbon transportation, or using more efficient buildings.

When it comes to energy consumption, real-time data monitoring can be a powerful tool for reducing energy use.

Organizations that can effectively manage their emissions can reduce their environmental impact and improve their bottom line.

Wrap Up.

Climate change is an ongoing global concern growing as businesses mature and new regulations are implemented.

Organizations worldwide can expect reduction targets to get more stringent as efforts to reduce climate change grow.

The good news is that organizations can onboard many end-to-end carbon accounting solutions to harness their net-zero initiatives.

This list provided some of the top carbon account software options today.
