About Us
SustainOpp is an independent partner for organisations that need to show real progress on sustainability
SustainOpp exists to close the gap between sustainability ambition and what actually happens in portfolios, operations and reporting. We bring together deep experience in ESG regulation, sustainable finance, data and transformation, applied inside some of the most demanding sustainability programmes in the market.
For each engagement, we assemble a senior-led team shaped to the brief, drawing on a trusted network of specialists where needed. Clients get the right balance of strategic perspective and delivery firepower – without unnecessary overhead.
We work as an extension of your in-house team, not as distant commentators. That means helping you design the policies, actions, targets, data architecture and governance you need, and staying close enough to ensure they work in practice. We judge success by outcomes you can point to: cleaner audit trails, clearer investor narratives, tighter risk control, lower operational friction and new opportunities unlocked. Reports and workshops are milestones, not the finish line.
Our Approach
Our apporach is underpinned by five core principles:
Foresight, not box-ticking
We stay close to the moving edge of regulation and market expectations – from CSRD/ESRS and ISSB to TCFD/TNFD, PRI and OECD guidance. Our focus is not on reciting acronyms, but on translating them into clear choices on scope, timing and focus, so clients can comply and use these frameworks as levers for improvement and positioning.
Strategy tied to value
We speak in the currency boards and investors care about: growth, margin, risk and cost of capital. Every initiative we support has a clear value rationale. By quantifying upside and downside, we help clients prioritise ESG effort where it genuinely moves financial and stakeholder outcomes.
End-to-end partnership
We stay involved from first diagnostic through to implementation and audit-readiness. We don’t hand over a strategy deck and disappear; we co-create solutions, support execution and refine them over time. Clients work with us as long-term partners, not episodic advisers.
Data-led and tech-enabled
We use technology, including AI and advanced analytics, to strengthen and accelerate sustainability programmes. From AI-enabled benchmarking to digital data capture and reporting, we reduce friction and improve the quality, consistency and usefulness of ESG information.
Straight dealing and trust
We operate with independence and integrity. Our advice is evidence-based and candid about constraints, whether data quality, organisational readiness or change fatigue. Building trust – internally and with external stakeholders – is not an outcome, it is a prerequisite.
Why SustainOpp?
Institutional-grade rigour, without institutional baggage. We combine the depth of major sustainability programmes with the focus of a specialist practice, delivering work that stands up to regulators, investors and stakeholders – and actually changes how capital, strategy and operations are run.
