Most Companies Are Flying Blind on Their Biggest Emissions Source

Here's the uncomfortable truth: Scope 3 emissions account for 65-95% of most companies' carbon footprints, yet the data to measure them properly is a mess. Suppliers don't have their own emissions data, methodologies vary wildly across the 15 GHG Protocol categories, and you're often forced to rely on estimates instead of real numbers. It's not just a reporting headache: it's fundamentally understating your climate impact.

The root problem? You don't control your supply chain, and your suppliers aren't equipped to give you what you need. Apollo's recent analysis breaks down why Scope 3 data rarely arrives ready to use, highlighting how smaller businesses in particular lack the infrastructure to track and share emissions data. Without standardized approaches, you're left piecing together invoices, receipts, and rough estimates while trying to figure out which of the 15 categories even apply to your operations.

So what's the fix? Start with the low-hanging fruit: focus on upstream categories like purchased goods, business travel, and employee commuting where data is more accessible and materiality is clearer. Work with frameworks like the GHG Protocol and CDP templates to bring consistency to your approach, and invest in supplier engagement early (even if the data isn't perfect at first). The goal isn't immediate perfection; it's building a transparent, repeatable process that actually gets you closer to the real numbers over time.
