Just like we need graphs to help us believe that 2025 has really been the hottest year on record, or to track the much-needed slowdown in global warming that could help us avoid irreversible tipping points, businesses too need to see data first-hand to believe it. Data that shows their carbon emissions clearly and helps them set realistic goals towards their sustainability targets.
Recently, I was reviewing carbon data with a client who was considering switching to enhanced CO₂e reporting. When we compared two different data sets, there was an “ah-ha” moment. The numbers showed that this company – a business with a high volume of corporate and events-related travel – had been over-investing in carbon offsetting. The travel manager realised that the savings from more accurate reporting would more than pay for the enhanced service. A simple example, but it demonstrates how better data doesn’t just improve credibility, it makes financial sense too.
Seeing is believing. When we see data presented in graphs or tables, it becomes tangible. There’s a source, a structure, something we can trust. In contrast, words are easy to say but they’re not always validated. That’s why, in sustainability, the story only matters if the numbers back it up.
Yet when companies suddenly find themselves under pressure to demonstrate sustainability action, the instinct is often to act fast rather than act accurately. Without robust data, knee-jerk decisions can lead to unintended consequences, such as cutting travel altogether. That might reduce emissions, but at what cost to sales, relationships, or growth? Good data gives you options. It can highlight opportunities to switch suppliers, move shorter flights to rail, or combine trips more efficiently, all while keeping the business moving.
Enhanced carbon reporting is still relatively new. For years, most organisations relied on standard DEFRA calculations. Now, as businesses demand more detailed insight, reporting tools are becoming more dynamic and accurate. The shift is clear: investing in good data upfront delivers benefits that far outweigh the cost financially, operationally, and reputationally.
There’s little point investing in Sustainable Aviation Fuel, carbon offsets, or removal projects if you can’t explain what those actions equate to. Let the numbers tell the story. Use data to show progress against carbon neutrality or net zero goals, and to highlight where attention is still needed. This year’s reductions or offsets only count for this year. Next year, the process begins again. Budgeting based on real data ensures that businesses are investing the right amount in the right places.
For travel and event managers, this is where sustainability becomes real. Numbers speak for themselves. If aviation emissions have dropped, the data will prove it. If the goal was to shift 20% of air travel to rail, the evidence is right there. Tracking progress throughout the year allows teams to adapt, refine and demonstrate impact, not just intention.
Good data doesn’t just measure progress. It drives it. And it won’t cost the earth (excuse the pun!).
