About Keslio

The sustainability team you can hand the hard part to

We built Keslio on a simple belief: meeting what your customers, investors, and regulators expect of you on sustainability should not require becoming an expert or standing up a team of your own. That work is our job, so it does not have to become yours.

Our mission

How can we support you?

Most people who come to us are not sustainability experts and have no wish to become one. They are a finance lead, an operations manager, or a founder who just got asked for an emissions number, a questionnaire, a report, or a policy, on top of their real job.

That is the problem we exist to solve. You bring us the goal or the question; we turn it into credible numbers, a clear report, or a practical plan you can stand behind. We solve the problem in front of you, without selling you a transformation program you did not ask for.

There are two ways to work with us. Ongoing, as a fractional sustainability team that carries the work month to month. Or one project at a time, when you need a strategy, a GHG baseline, a report, or a rating done once and done right. The services below spell out both.

However you work with us, the standard does not change. Every number comes with the honest caveats and the sources behind it, so you can defend it to whoever asked. Our free emissions calculator and the public data it runs on are there for one reason: so you can see we work this way before you ever pay us.

Keslio is part of Lanmea, a group of specialist advisory firms. So when a sustainability question turns into a bigger one, we can also bring in B2B marketing, technology and data, or corporate finance expertise, and you have one team to grow with instead of a new search each time.
