Can reducing your company's carbon footprint help your business?
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 and provide more precise emissions calculations.
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 gasses 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.
Why else is reducing carbon emissions with a carbon management platform a good idea?
Additional benefits to carbon accounting include:
- Allows for improved emissions data collection and simultaneously integrates data analysis to help curate personalized 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.

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.

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.
How do I choose the right carbon accounting software for my company?
Choosing the right carbon accounting tool will vary depending on your business needs and goals.
However, there are a few things that companies (regardless of size and sector) should consider before choosing the carbon accounting tool for them.
Here are some things to think about when deciding which platform will prove most useful to optimize your carbon reduction strategy:

- Decide which platforms are best able to align with the necessary standards and environmental protocols in your region
- Determine the cost effectiveness of each platform and which carbon management investment is most feasible for your business
- Pick a user-friendly platform that allows your employees to collaborate with stakeholders and your supply chain with ease
- Ensure that that carbon accounting tool of your choice makes data security and privacy protection a top priority
