ESG Investing

ESG investing is the practice of weighing environmental, social and governance factors alongside financial ones — screening out some businesses, favouring others, pressing companies on their practices — because these factors affect risk and return, and because investors' beneficiaries and regulators require it. In private markets it is a diligence workstream and a reporting duty; in fintech the S and G — conduct, data, governance — matter most.

Also known as
ESG, Sustainable investing, Responsible investing
Used at
fund selection by institutional investors, fund managers' investment and ownership policies, acquisition diligence, and the reporting regimes — the EU's SFDR for funds, CSRD for companies, the UK's stewardship code
Binding
partly — SFDR classifies funds (Article 6, 8 or 9) and requires disclosure; CSRD requires large companies to report; the substance of what "ESG" means remains contested and has been politicised in the US
Typical practice in private equity
an ESG questionnaire in diligence, a policy in the LPA, annual portfolio reporting to LPs on a set of KPIs, and exclusions (weapons, tobacco, some fossil fuels); venture funds apply lighter versions
Typical fintech content
governance and conduct (how the company treats customers, its complaints and regulatory record), data and privacy, financial inclusion and affordability of credit, AI fairness, cyber security, and the diversity of the team
Parties
LPs and their beneficiaries, fund managers, portfolio companies, acquirers, and the regulators and rating agencies who define and score it

How ESG investing works in practice

A pension fund's beneficiaries and its regulator expect it to consider sustainability; it writes ESG into its manager selection. A private equity fund raising from it adopts a policy: an exclusion list, an ESG assessment in every deal's diligence, a set of KPIs reported yearly, and an SFDR classification for the fund. When the fund looks at a fintech, the assessment is mostly governance and conduct: is the board independent, does the compliance function have teeth, what do complaints and the regulator's correspondence show, how are vulnerable customers treated, how is customer data used, is the lending fair and affordable, is the AI in the credit model explainable. The findings go into the price and the 100-day plan the same way a finance finding would.

Whether ESG improves returns is argued in both directions with data; what is not argued is that a fintech with a poor conduct record is a regulatory risk, that a lender whose affordability checks fail is a redress liability, and that a company whose data practices break the law is worth less — which is ESG under a name a chief risk officer would recognise. The reporting regimes add cost and, in the EU, a classification that affects which LPs can invest.

For an acquirer, the ESG diligence of a fintech target is the conduct diligence with a different cover page, and worth doing under either.

Example

A fund classified under SFDR Article 8 looks at a consumer-lending fintech. Its ESG diligence finds: affordability checks that the regulator has questioned in two letters; a complaint rate twice the sector's; a credit model with no explainability documentation; a board with no independent director; strong data security; a workforce with a 40% gender gap in senior roles. Financially the company is excellent. The fund prices a €4m remediation programme into the deal, makes an independent chair and a model-governance framework conditions of its 100-day plan, and reports the KPIs to its LPs from year one. A rival fund without an ESG process bid €5m more and lost the deal when its LP advisory committee asked about the regulator's letters.

Common mistakes

- Treating ESG as a questionnaire rather than as conduct, data and governance diligence with consequences. - Reporting KPIs nobody in the fund uses to make a decision. - Confusing an SFDR classification with a promise about returns. - Excluding sectors by label and missing the conduct risk inside the sectors kept. - Ignoring that in a fintech the "S" and "G" are the licence.
