In short, there's plenty who can! The Sumday advisor directory includes advisors who know how to use Sumday and how to do your carbon accounting. You can reach out to them directly to understand what's involved for your business and their fees.

Why would my business need to be carbon accounting to an audit ready standard?

You may not have a legal obligation to do this of course, but if any of the following applies to you, carbon accounting properly can be increasingly important. Here are some common reasons: You want to make sustainability related claims online or in your marketing materials "we're low carbon, carbon negative, environmentally friendly, a lower carbon option" for example. It's greenwashing if you have no evidence to back this up You supply goods or services to larger organisations, you may be asked for this data to meet changing procurement policies. You want to provide your carbon emissions as a point of difference so customers know you're taking this seriously. You want to apply for grants to access funding for sustainability initiatives, it's becoming a common question. You want to understand who of your suppliers are taking sustainability seriously and accounting for their emissions. You want to be able to tell the story of your progress around emission reduction year on year.

Do I need to use my accountant for carbon accounting?

You don't have to, but like financial accounting you may need their skills and support to do this to an audit ready standard. Often they'll have the data you need and can ensure it's complete, reducing the risks of mistakes and accusations of greenwashing.
