Sustainability is not just about ticking boxes or meeting regulatory requirements. It is about building a mindset that puts environmental, social and governance (ESG) considerations into everyday decisions across an organisation. A strong ESG culture is often the difference between superficial adoption and genuine, lasting change. In this article we look at how private equity managers and portfolio companies can make sustainability part of how the business operates, and why that pays off.

1. Leadership commitment
A shift in culture begins at the top. When the leadership team champions ESG goals, people at every level feel encouraged to align their work with them. This might include:
- Regular communication on ESG progress, including where targets are being missed.
- Budgets earmarked for sustainability initiatives.
- ESG metrics in bonus or promotion criteria.
2. A clear mission and values
Formalise your sustainability ethos in the company's mission statement and core values. Doing so clarifies expectations and attracts talent that wants to work for a responsible business. Referencing widely accepted frameworks, such as the UN Sustainable Development Goals, provides a shared vocabulary and global context.
3. Employee training and engagement
To embed ESG into day-to-day activities, employees need to understand both the how and the why:
- Workshops and seminars: sessions on carbon accounting, waste reduction or responsible sourcing.
- Internal platforms: an ESG portal where staff can share ideas, track progress and celebrate milestones.
- Recognition: acknowledging teams or individuals who lead impactful initiatives.
Progress has to be measurable to be motivating. A solid data infrastructure helps; our guide to modernising ESG data management in portfolio companies explains what that looks like.
4. Aligning ESG with operations
Sustainability should not sit in a silo. Integrate ESG principles into core processes:
- Procurement: vet suppliers for labour practices and environmental performance, and ask for their emissions data.
- Product design: favour lower-impact materials and reduce resource intensity.
- Financial planning: factor ESG metrics into capital expenditure decisions and link them to financing advantages, such as the ESG ratchet in lending agreements.
5. Fostering a collaborative culture
ESG thrives where information and responsibilities flow across departments. Encourage cross-functional teams, bringing together marketing, operations and finance, to tackle sustainability challenges together. This cross-pollination of ideas often produces the most practical solutions.
6. Storytelling and transparency
A strong ESG culture is built on honest communication. Share successes regularly, such as a significant drop in waste or a new community programme, and acknowledge setbacks and lessons learned. Openness builds trust among employees, LPs and external stakeholders alike. For how this extends to investors, see our article on sharing live ESG data with LPs.
7. Overcoming resistance
Cultural change can meet scepticism, or outright hostility, if employees see sustainability as extra work without benefit. Address this by:
- Linking ESG to people's own goals: show how efficiency improvements simplify workloads or free up resources for better work.
- Two-way communication: make sure concerns from frontline staff reach management, and that strategic decisions are explained in return.
- Piloting initiatives: start with a project that delivers a quick, visible win before scaling across the organisation.
8. The long-term payoff
When ESG is embedded in culture:
- Risks surface earlier: employees proactively flag ethical or environmental issues.
- Reputation improves: a sustainability-driven workforce attracts customers, partners and investors.
- Innovation follows: the constant search for improvements spills over into operations, product development and new markets.
Beyond compliance
As we discuss in our five-year outlook for ESG in private equity, the next wave of ESG work goes beyond compliance and risk management. Organisations with a deeply ingrained sustainability culture tend to adapt faster to new rules, adopt new technology sooner and lead their sectors on resilience and performance.
Building a sustainability mindset is not a one-off project but an ongoing cultural journey. By securing leadership buy-in, integrating ESG into mission and operations, and empowering employees through training and transparent communication, private equity managers can create an environment where ESG principles drive both ethical and financial gains. A shared, trusted set of numbers is what keeps that culture honest: Manglai's carbon footprint software gives every team in a portfolio company the same view of its emissions and progress.
