We help companies and investors integrate sustainability.
Whether you are answering your first customer request or building a full sustainability program, we turn each step into numbers, reports, and plans that hold up and move you forward.
What's on your desk?
A request with a deadline
A customer, platform, or investor asked for emissions data, a questionnaire, or evidence. Send it to us and we'll tell you exactly what it needs, free.
Building it properly
You want a real emissions baseline, a credible report, a better rating, a strategy, or a standing sustainability team. Start with the service that fits.
You're an investor
You need sustainability handled across a portfolio: diligence, monitoring, value creation, or an investment strategy that holds up.
The work we take on
Every engagement starts from what you actually need, and ends with something you can use: numbers, documents, answers, decisions.
All services →For companies
Supplier Request Support
A customer or platform asked your company for sustainability data. Keslio reads the request, tells you what it needs, and prepares a response you can defend. Free first review.
Fractional Sustainability Team
Sustainability keeps landing on your desk and it is not your actual job. You need someone to own it without hiring a full-time role.
Sustainability Strategy
You know sustainability matters to your customers and investors, but you do not have a plan you can actually point to.
GHG Emissions Calculations
Someone asked for your emissions and you need an answer that holds up. We calculate your Scope 1, 2, and 3 emissions (your direct, your energy, and your value-chain footprint) with the method and evidence to back every figure, ready for a report, an investor, or a customer.
Reporting and Communications
You have to publish something about your sustainability, and you are worried about saying too much, too little, or the wrong thing.
Ratings and Certifications
A customer wants you rated on EcoVadis, or you are chasing a certification, and the questionnaire is longer than you expected.
For investors
Portfolio Management
You need sustainability data across your portfolio, and every company reports it differently, if at all.
Investment Strategy Development
Your LPs, regulators, or your own commitments expect a responsible investment approach, and right now it is more intention than process.
