Our Approach

ESG investing, done with discipline.

Since 2000 we have selected companies on environmental, social, and governance strength — one proprietary screen, applied to every holding, with no compromise on rigour or returns.

From your values
to a working portfolio.

One standard, four disciplines: every holding must qualify on its own merits, and every portfolio must earn your trust through what it reports as much as what it returns.

Phase 01

Understand Your Values

Every relationship starts with a conversation, not a questionnaire template — establishing your goals, time horizon, and the values your portfolio must reflect before a single holding is considered.

Phase 02

Screen Every Holding

Our proprietary multi-factor ESG screen draws on third-party data, company disclosures, and 26 years of in-house research. Each company qualifies on its own merits, independently — or it does not qualify at all.

Phase 03

Construct the Portfolio

We build a diversified allocation that is 100% ESG from the ground up, then rebalance and reinvest dividends automatically — with sector and company exclusions honoured as your values evolve.

Phase 04

Report What Matters

Reporting goes beyond performance: carbon footprint, clean energy exposure, diversity scores, and the share of capital in positive-impact activities, so you can see the discipline at work.

What Sets It Apart

Differentiators of our approach.

Earth seen from the lunar surface
ESG labels are cheap. A screen with 26 years of research behind it is not.

Every holding qualifies independently — never bundled ESG-labelled funds

Fiduciary duty at all times, not only at the point of recommendation

Sector and company exclusions customised to your values

Impact reported alongside performance

Our Values

The commitments that keep the approach honest.

Evidence over labels

Claims are verified against data and disclosures — a label alone has never qualified a company for our portfolios.

Transparency throughout

Asset-based fees, disclosed conflicts, independent custody — every part of the relationship can be verified.

Impact you can measure

Carbon footprint, clean energy exposure, diversity, and positive-impact allocation reported alongside returns.
