New Standards from 2025
Carbon accounting is no longer a niche capability, it’s becoming a mainstream compliance requirement. From 2025, the largest companies in multiple jurisdictions, including Australia, New Zealand, the UK, and the EU, will be required to report their emissions data in annual reports under new sustainability disclosure standards. Limited assurance will be mandatory at first, with a pathway to reasonable assurance already mapped out. That’s not just environmental reporting, that’s accounting. And who better to call in when assurance is on the table than the firm already trusted with the financials?
But what if your clients aren’t over required revenue thresholds?
Even if your clients fall below the compliance threshold, they’re likely part of a larger company’s supply chain. When a big company lends to or buys from an SMB, the emissions from that product or service become part of their Scope 3 emissions which they will need to account for. And without actual data from their suppliers, these companies are forced to use industry-average estimates by taking the total spent and multiplying it by an average emissions factor for that product. Under this approach, unless a company spends less with your client, those emissions won't come down. If 90% of a companies carbon footprint is based on that method - you can see why coporates will struggle to meet targets or credibly show reduction.
In 2025, leading businesses are asking a critical question:
How can we collect real emissions data from our supply chain without creating unreasonable burdens?
The answer: integrate carbon into the normal course of business — just like financials. And with the right tools, it’s both affordable and scalable.
That’s where you come in. As an advisor, you already hold much of the data. Adding carbon to your offering helps your clients stay compliant, credible, and competitive and positions your firm as essential in this next wave of reporting.
