ONTOS

Sustainability,
turned into action.

Ontos helps businesses, investors and financial institutions turn sustainability priorities into practical strategy, stronger decisions and lasting progress.

Five ways to work together.

From a defined advisory question to embedded leadership that owns the work end to end.

  1. A strategy is only useful if it decides something. Ontos helps you set priorities, design governance and build a roadmap that holds up in day-to-day work, then defines the KPIs and targets to track it. The result: a prioritised set of objectives, a governance model, a sequenced roadmap and decision materials ready for management or the board.

  2. Responsible investment only works when it lives inside the investment process, not beside it. Ontos builds policies and frameworks your teams can actually use — from exclusions and ESG integration to sustainable finance frameworks for labelled instruments. What you're left with: a strategy and policy, integration procedures, and materials ready for investment committees and boards.

  3. Good due diligence answers the question a decision-maker is actually asking, not just a score. Ontos assesses sustainability risk across deals, managers and portfolios — including climate and nature-related exposure using methods such as ENCORE — and sets out what it means for the investment, with findings written for the committee that has to decide and a follow-up plan with owners and timelines.

  4. Reporting is the visible end of a longer chain: collection, validation, calculation and judgement. Ontos strengthens that chain — GHG accounting, gap assessments against CSRD, ESRS, SFDR and TCFD, and disclosure reviews — leaving behind a documented, repeatable reporting process, not just a one-off set of figures.

  5. Some sustainability questions need more than advice — they need someone to own them. As an interim sustainability manager, Ontos works inside your organisation with a defined mandate, clear priorities and a planned exit, building internal capability as it goes. The outcome: continuity, named ownership and a clean handover.
