What Is Ethical & Purpose-driven Investing?
Ethical investing means choosing investments based on both financial return and personal values. It’s no longer a niche—mainstream investors increasingly want their portfolios to reflect their beliefs. But within this space, there are three main strategies: ESG, SRI, and impact investing.
- ESG focuses on a company’s environmental, social, and governance practices.
- SRI actively screens out or includes companies based on moral criteria.
- Impact investing aims to generate measurable positive change alongside financial returns.
You don’t have to pick just one. Many investors blend these approaches. But to do that wisely, you need clarity. Let’s dive deeper.
ESG Investing: The Data-Driven Approach
ESG stands for Environmental, Social, and Governance. It’s a framework used to evaluate how a company manages risks and opportunities related to these three pillars. ESG investing is less about avoiding “bad” companies and more about finding well-managed, sustainable businesses.
What ESG Looks For
- Environmental: Carbon emissions, resource efficiency, pollution control.
- Social: Employee relations, diversity, community impact.
- Governance: Board independence, executive pay, shareholder rights.
Investors use ESG scores from agencies like MSCI or Sustainalytics to compare companies. A high ESG score suggests a company is better prepared for long-term challenges. Studies even show that strong ESG practices can correlate with lower risk and solid returns.
ESG investing is not about sacrificing profit for purpose. It’s about using non-financial data to make smarter financial decisions.
SRI Investing: Values-Based Screening
Socially Responsible Investing (SRI) is older and more direct. It applies negative screening (excluding industries like tobacco, firearms, or fossil fuels) and positive screening (seeking out companies with strong social records). SRI is deeply personal—your “sin stock” might be someone else’s income staple.
Common SRI Filters
| Negative Screens | Positive Screens |
|---|---|
| Tobacco | Renewable energy |
| Weapons | Fair labour practices |
| Gambling | Community development |
| Adult entertainment | Gender equality |
SRI is often more rigid than ESG. If you feel strongly about avoiding certain sectors, SRI gives you that control. However, it may limit diversification and potentially lower returns if too many exclusions are applied.

Impact Investing: Purpose First, Profit Second
Impact investing goes a step further. Here, the intention is to generate measurable social or environmental benefits alongside a financial return. Think of it as investing with a mission.
Key Characteristics of Impact Investing
- Intentionality: The investor actively seeks positive outcomes.
- Measurability: Success is tracked through metrics like jobs created, carbon reduced, or lives improved.
- Range of returns: Some impact investments offer market-rate returns; others accept below-market returns to achieve greater impact.
Examples include community development bonds, green bonds, or private equity in affordable housing. Impact investing is often done through specialised funds or direct investments. It’s not passive—you need to monitor the impact just as you monitor profits.
Impact investing is for those who want their money to be a force for good, not just a silent partner.
ESG vs. SRI vs. Impact Investing: A Quick Comparison
| Aspect | ESG | SRI | Impact Investing |
|---|---|---|---|
| Primary goal | Risk management & sustainability | Moral alignment | Tangible positive change |
| Method | Scoring & integration | Screens (negative/positive) | Direct investment in solutions |
| Financial return expectation | Market-rate | Market-rate (with possible trade-offs) | Can be below-market or market-rate |
| Measurement | ESG rating | Screen compliance | Metrics (e.g., CO2 reduced) |
| Typical investor | Mainstream institutions | Values-driven individuals | Foundations, HNWIs, activists |
How to Choose the Right Approach for You
Start by asking yourself: what matters most to me? If you want to manage risk while staying invested broadly, ESG is a great starting point. If you have strong moral convictions and want to avoid certain industries, SRI gives you that control. And if you want your money to actively solve problems, impact investing is your path.
You don’t have to commit to one. Many investors combine strategies—for example, using ESG as a baseline and then applying a few SRI screens. The key is to be consistent and informed.
