Xero and Sumday team up on free carbon accounting tools

This article was contributed by Sustainable Choice Group.

If you’re a Xero customer, you’re already measuring your carbon… but you might not know it.

If you’re using Xero to manage your business, you now have access to something seriously valuable: a free, fully integrated carbon accounting solution through Xero and Sumday.

Xero has partnered with carbon accounting platform Sumday to give all Xero customers 12 months free access to Sumday’s carbon reporting tools. It’s simple, cost-effective, and available now via the Xero App Store.

And this isn’t theoretical data. Sumday pulls directly from your general ledger to help you estimate and track your carbon emissions using the same numbers you already use to manage your finances, meaning it’s just as good and just as secure. 

This partnership makes sustainability reporting more accessible, and less dependent on expensive resources or endless spreadsheets for small businesses.

Why this matters

If you’ve ever had a client, supplier or procurement partner ask for your emissions data, or you know it’s only a matter of time, this is the kind of tool that can save you a lot of headaches.

Until now, emissions tracking might have felt complicated for small businesses. But expectations are rising fast. Regulators, retailers, and even your customers are beginning to expect credible, trackable environmental data. And they don’t just want it from large corporates, they’re expecting it across the supply chain.

Sumday lets Xero users track emissions across their business with just a few clicks. It pulls in your financial data, applies emissions  factors, and gives you visibility into your biggest areas of impact, without the technical guesswork.

What Xero customers get

If you sign up before 1 April 2026, you’ll receive:

• 12 months free access to Sumday
• Unlimited users (for businesses) or up to 5 staff (for accounting firms)
• Access to Sumday Academy for training
• A carbon accounting support desk managed by CPAs
• Sumd[AI]: an AI assistant to help generate reports and interpret standards
• Tools to collect and share data with your suppliers and customers
• A unique, branded URL ‘Profile’, allowing you to communicate your carbon emissions easily to others

For accountants and bookkeepers, this also includes a firm-level account to manage your own carbon reporting and build capability across your client base.

And if you’re wondering — yes, we use it too

At Sustainable Choice Group, we use Xero for finance and Sumday for carbon accounting. We run our numbers through this exact integration. It’s simple and affordable for our little start-up (FREE) which is exactly what small businesses need if we’re going to meet rising expectations without over-engineering the process.

And while this isn’t a sponsored post, it’s worth noting that Xero is one of our most loyal customers. So, while there’s no formal collaboration behind this write-up, you could call it values-aligned.

Because when a major brand like Xero invests in helping thousands of small businesses take climate action seriously, we think that deserves attention.

What this enables

With this setup, you can:

• Build your first carbon baseline without hiring a consultant
• See where your emissions are coming from (by category or project)
• Start measuring and managing your impact with real data
• Respond confidently to customer or retailer requests for ESG reporting
• Stay ahead of emerging carbon reporting requirements (instead of scrambling later)

It’s a low-friction way to start, especially for businesses that need data but don’t have in-house resources (or extra budget lying around).
