Ever wondered what goes on behind the scenes as we help global clients untangle the complexities of travel-related CO2 emissions? Here’s a glimpse into a typical day from one of our sustainability analysts—a role that’s part detective, part data scientist, and part trusted advisor.
Every day starts with new questions from our clients. Increasingly, they want to understand not just how much CO2 their business travel generates, but what they can do about it. For example:
It's not just about the numbers anymore—clients want actionable insights and scenario modelling to guide real decisions. They're looking for solutions, not just reports.
Flexibility is key. Most clients default to DEFRA for emissions calculations, but even that isn't as
straightforward as it sounds. There are choices to make: include or exclude radiative forcing, how
to treat different travel classes, whether to count "well to tank" fuel emissions, and how to define
short versus long haul. DEFRA is widely used, making it great for benchmarking, but it's not always
the most sophisticated tool for every unique situation.
Some clients bring their own blend of government, third-party, and in-house methodologies. The most
important thing is that whatever approach is used, it’s well-documented, applied consistently, and
fully auditable. That consistency is non-negotiable.
And the differences can be dramatic. We recently modelled the impact for a client comparing EPA and
DEFRA methodologies and found that total emissions could vary by as much as threefold. That’s a huge
swing—one that can affect everything from sustainability targets to critical audit outcomes. It
truly underscores why getting the methodology right and being clear about it is so vital.
We’re seeing a clear shift: clients are moving from cost-based to distance-based reporting. For air
travel, that’s relatively easy. For ground transport—think taxis—it takes a lot more digging to get
accurate numbers. It's a journey, not a sprint, but the direction is clear.
There’s also a move toward scenario-driven analysis. Clients want to see the impact of specific
policies, like mandating rail for trips under a certain distance, or limiting the use of business
class. And it’s not just about their own reporting anymore: our clients' customers are demanding
more granular data to help with their own supply chain emissions disclosures. This means we’re now
breaking down emissions at the project, location, or even facility level. Talk about getting into
the weeds!
Here’s the reality: accurate CO2 reporting lives and dies on data quality. Travel data is messy—refunds, exchanges, cancellations, and the tangle between expense data and travel booking data can all lead to errors. We’ve seen clients accidentally double-count emissions because they didn’t understand the difference between what was paid on a BTA card and what was later expensed. It happens more often than you'd think!
That’s where our expertise comes in. We’ve developed a suite of workflows and algorithms to clean,
combine, and calculate CO2 from disparate data sources. Our approach isn’t just about crunching
numbers; it’s about understanding trends and ensuring that assumptions are applied consistently, so
the insights are reliable, even when the data isn’t perfect. We make sense of the chaos.
We also help clients model the impact of switching methodologies, so they can see what would happen
if they moved from DEFRA to EPA, or vice versa. This transparency is vital for auditability and
stakeholder trust. No surprises, just clear understanding.
Without our help, clients would face a mountain of work—debating methodologies, wrangling messy
data, and struggling to draw meaningful insights, especially from historic records. The risk of
failed audits or undue scrutiny on travel emissions numbers would be much higher. Imagine the
headaches!
We make CO2 reporting easy: we do the heavy lifting on data, advise on best practices, and ensure
consistency and audit-readiness. In a world where audit requirements are tightening and supply chain
partners are asking tougher questions, that peace of mind is invaluable.
In short: Our days are spent making sense of complexity, turning messy data into actionable
insights, and helping clients not just measure—but manage—their travel emissions. And as
expectations rise, from both regulators and the market, that work has never been more important.
