As more companies seek to reduce their carbon dioxide and greenhouse gas emissions, carbon accounting softwares 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 softwares. 

Using carbon accounting softwares 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 softwares 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.

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 towards 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. 

This is where carbon accounting softwares come in handy. Running a business is difficult enough, so that’s why many companies in 2023 are seeking carbon accounting softwares to help them determine their current carbon emissions and create successful mitigation strategies to reduce their carbon footprint.

What are carbon accounting softwares?

Carbon accounting softwares are third parties that help you with carbon accounting in order to manage and support a company in the efforts to reduce their carbon emissions.  

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

Despite the great benefits of carbon accounting softwares, they’re still relatively new – and many companies have yet to subscribe to the potential positive impacts carbon accounting softwares could yield for their company. 

Carbon accounting softwares seek to 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 gasses that provoke global warming.

According to the Greenhouse Gas Protocol, the term “carbon emissions” can refer to methane, perfluorochemicals, sulfur, hexafluoride, hydrofluorocarbons and 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. 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 softwares help to establish greater transparency and ultimately, better communication between stakeholders and other potential investors. 

As more companies join the movement to achieve net-zero emissions by 2050, carbon accounting and seeking third party assistance to manage carbon emissions through carbon accounting softwares is more imperative to success than ever. 

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. 

It’s no easy task to decide what the best carbon accounting software is for you, as every business is different and requires specific needs to meet their individual environmental goals.
