As more companies seek to reduce their carbon dioxide and greenhouse gas emissions, carbon accounting software have become more useful than ever. 

Companies are growing cognizant of their environmental impact, and therefore – many have sought third party assistance to manage and reduce their carbon footprint through carbon accounting software. 

Using carbon accounting software allows companies to be held accountable for their new environmental goals, methods to reduce their emissions, monitor their emission reduction progress, and be provided with expert advice on how to proceed with their business in a more sustainable manner. 

But what are the best carbon accounting software as of 2024?

In this article, we'll explain what carbon accounting is, why it's important to invest in carbon accounting software, and the best carbon accounting software as of 2024.

What is carbon accounting?

Carbon accounting, which is sometimes referred to as greenhouse gas accounting – is a process a company uses to measure the amount of carbon dioxide emissions they are responsible for so that they may equally trade carbon credits between states, companies, and individuals in the carbon market.

Emissions data to help a company determine their carbon emissions can often prove difficult for companies to calculate alone, making carbon management software a great way for companies to be guided in the best carbon accounting method suitable for their business and ensure proper data collection in addition to the most effective carbon reduction targets.

💡 In fact, the market for carbon accounting software is growing exponentially – with the carbon accounting software market reaching a new high of $12.73 billion USD in 2022, $15.32 billion USD in 2023, and expectations to hit a high of $18.52 billion USD in 2024.

A carbon accounting platform can help companies to collect carbon data, reduce their future energy emissions and energy consumption, simplify their carbon reporting process, and even adhere to a major climate disclosure regulation such as the CSRD or SEC Climate Disclosure Rule. For example, carbon accounting allows companies to fairly exchange carbon credits and determine how much they should invest into a carbon offset project

Carbon accounting is a great first step towards developing a more sustainable business model and reducing carbon emissions. After all, it’s hard to pinpoint which carbon reduction measures to take if you don’t know how much carbon emissions you’re producing in the first place – but carbon accounting software can help companies to accurately measure and reduce emissions effectively.

Essentially, carbon accounting operates in a similar manner to financial accounting – but instead of trying to manage a company's financial data, the goal is to calculate emissions and process environmental data.

👉 This is where carbon accounting software come in handy. Running a business is difficult enough, so that’s why many companies in 2024 are seeking third party solutions such as carbon accounting software to help them determine their current carbon emissions and create successful mitigation strategies to reduce their carbon footprints and improve their overall sustainability efforts.

What is carbon accounting software and why use it?

Carbon accounting software is a third party solution to help you with carbon accounting in order to manage and support a company in the efforts to reduce their carbon emissions.  

Carbon accounting software can help keep companies informed about their carbon emissions, and actively seek to reduce their carbon footprint and future emissions as their company grows. 

💡 Despite the benefits of carbon accounting software, they’re still relatively new – which means that many companies have yet to subscribe to the potential positive impacts carbon accounting software could yield for their company.

Carbon accounting software can help companies reduce their carbon emissions. However, it’s important to note that the term “carbon emissions” is a generic term that is used to represent all types of greenhouse gases that provoke global warming.

According to the Greenhouse Gas Protocol, the term “carbon emissions” can refer to:

  • methane
  • perfluorochemicals
  • sulfur
  • hexafluoride
  • hydrofluorocarbons
  • nitrous oxide

Companies that choose to commit to a carbon accounting software allows them to improve their management of the carbon emissions that they are responsible for creating. Carbon accounting can also allow for better financial opportunities, as stakeholders are likely to take interest in a company that is seeking to reduce their carbon emissions.

💡 Carbon accounting software help to establish greater transparency and ultimately, better communication between stakeholders and other potential investors. 

Additional benefits to carbon accounting include:

  • Allows for improved emissions data collection and simultaneously integrates data analysis to help curate personalised sustainable practices and set reduction targets
  • New insight on the indirect emissions produced on behalf of your value chain or supply chain
  • Passive or AI powered carbon measurement can help companies to measure their GHG emissions and monitor their supply chains with ease
  • Facilitate business growth by adhering to science based targets and mandatory reporting
  • Breaks down a company's emissions sources into three different scope categories to allow for more precise emissions tracking, activity data collection, and overall progress tracking

As more companies join the movement to work towards net-zero emissions by 2050, carbon accounting and seeking third party assistance to manage carbon emissions through carbon accounting software is more imperative to success than ever. This is because planning towards net-zero emissions, which is where a company will counterbalance all of their carbon emissions entirely, requires careful planning that can be made easier through the use of a carbon accounting software. 

👉 If you choose the right carbon accounting software for your business, you could see a great improvement in the reduction of your carbon emissions. However, it's no easy task to decide what the best carbon accounting software is for your company – as every business has a different carbon agenda and requires specific needs to meet their individual environmental goals.

Carbon Analytics relies on data, automated reports, financial accounting activity, and historical trends to assist their customers with their carbon emission reduction tactics. 

While it is admirable and impressive that Carbon Analytics has illustrated the time-saving benefits of utilizing technology to make monitoring finances and emissions at the same time easier, it is important to note that Carbon Analytics may not be the best carbon accounting software if you’re seeking a well-rounded carbon accounting experience. 

👉 However, that is not to negate that Carbon Analytics is well suited to SMEs looking to manage their financial patterns and carbon emissions reduction tactics simultaneously – since Carbon Analytics offers user-friendly graphs and visuals to help SMEs develop the best roadmap for success.

Why is it important to invest in carbon accounting and enterprise software?

Your company could benefit from deciding to commit to carbon accounting software for several reasons, as it helps businesses to improve their sustainability experience and allow them access to advanced decarbonisation tactics on a single platform.

First off, using carbon accounting software is a great first step towards developing more sustainable business habits. As global warming continues to persist, investors and customers are seeking to partner or purchase products or services from businesses that seek environmental and social just as well instead of only financial success.

💡 In other words, investors and customers want to know that the product or service they are buying isn’t going to worsen the environmental state more than it already is – and that revenue or gaining business popularity isn’t their sole business incentive. 

Carbon accounting also helps to establish transparency and prevent future greenwashing. Committing to the use of carbon accounting software can also provide statistical evidence that is viable to prove that your company is indeed making an effort to reduce your carbon emissions.

While this remains pivotal for large enterprises, it is especially important for smaller businesses looking to establish themselves and ensure their sustainability initiatives are aligned with the GHG protocol.

Not only will using carbon accounting software help you to reach net-zero emissions and maintain or reduce your carbon footprint, but using carbon accounting software can also stimulate financial growth within a company or benefit financial institutions themselves. Since investors, employees, and consumers are growing increasingly interested in sustainability – the odds of attracting new consumers, investors, and employees increase alongside tangible dedication towards reducing carbon emissions and helping the environment.

Carbon accounting software can also help companies comply with new laws or government requirements more easily. Since carbon accounting is a verified process, politicians and lawmakers will be more likely to approve of a company’s dedication to reducing their carbon footprint and confirm  that they are complying with the current environmental regulations more easily. 

👉 All in all, committing to the use of carbon accounting software can only benefit everyone involved. It helps to reduce your carbon emissions, attract more investors and consumers, increase financial revenue, and ultimately grow your business – all while helping the planet.
