Evaluating ESG / Sustainable Funds: What to Look For

ESG investing has become far more common over the last few years. What used to sit in a fairly niche corner of the investment world is now something many investors actively ask about, particularly younger investors and people reviewing pensions for the first time.

A lot of people simply want their investments to feel more aligned with their personal values. If your money is being invested somewhere for the next 10, 20, or 30 years, it is understandable to want some idea of what businesses you are backing along the way. The problem is that ESG investing is not nearly as straightforward as the marketing sometimes makes it sound.

Two funds can both call themselves sustainable and still invest in completely different ways. One may avoid oil companies entirely. Another may hold some of the world’s largest energy firms because the manager believes they are improving their environmental standards or investing heavily into transition projects. That tends to surprise people at first.

One thing that becomes obvious fairly quickly is that ESG is not one single investment style. Some funds focus heavily on climate and environmental issues. Others are more concerned with governance standards or workplace ethics. Some simply exclude industries investors may not want exposure to. Others actively target businesses they believe are creating positive long-term change. You end up with a huge range of approaches all sitting under the same ESG umbrella.

A large number of ESG funds use what is called negative screening. In simple terms, they avoid certain sectors entirely. Typically that means things like tobacco, gambling, weapons, coal, or fossil fuels. On paper, it sounds relatively straightforward. But even then, every fund tends to draw the line in slightly different places. One manager may exclude all oil and gas exposure completely. Another may allow investment into companies they believe are transitioning towards greener energy production. Some allow small percentages of revenue exposure. Others do not. It is rarely as black and white as people expect.

Then you have funds focused on positive impact investing. These tend to invest in areas such as renewable energy, clean technology, healthcare innovation, water infrastructure, or sustainable agriculture. For some investors, these funds feel more aligned with what they actually want their money doing. But there is another side to that as well. Impact-focused funds can sometimes become quite concentrated in certain sectors. Technology exposure, in particular, can creep up quickly. That can lead to bigger swings in performance during difficult markets. Which is fine if the investor understands that going in. Less fine when they assumed “sustainable” automatically meant stable.

This is probably one of the biggest practical issues with ESG investing right now. Words like ethical, sustainable, responsible, climate-aware, green, impact, transition… they all sound reassuring. But they do not tell you very much on their own. Some funds with very strong ESG processes barely mention it in the title. Others lean heavily on sustainability language while applying fairly limited screening underneath. So the name itself is not really enough.

This is the bit most people skip because, understandably, fund documents are not exactly thrilling to read. But the investment policy is usually where you find out what the manager is actually doing. Are they excluding sectors? Using ESG ratings? Engaging directly with companies? Investing only in businesses meeting certain sustainability criteria? Trying to reduce carbon intensity compared to the wider market? That detail matters more than the branding. Quite often we see investors buy a fund because they like the sound of it, then only later realise it still holds businesses they were hoping to avoid.

This sounds obvious when written down, but it is worth saying because ESG funds are sometimes discussed as though they sit outside normal market risk. They do not. Some sustainable funds can actually be more volatile than broader market investments depending on how concentrated they are.

We have seen periods where ESG-related sectors performed exceptionally well. Clean energy and technology companies attracted huge amounts of investor attention at various points over the last decade. But investment trends move in cycles. When large amounts of money flow into the same areas, valuations can become stretched quite quickly. Then markets correct and investors suddenly realise sustainable investing is still investing. Prices still fall sometimes. That catches some people off guard because the word “sustainable” sounds safe and steady. The reality is more complicated than that.

A portfolio still needs balance regardless of how ethical or sustainable the investments are. One thing we see fairly regularly now is investors holding multiple ESG funds across pensions, ISAs, and workplace schemes without realising they all own very similar companies underneath. A lot of sustainable funds naturally tilt towards sectors like technology, healthcare, industrial innovation, or large multinational growth businesses. There is nothing wrong with that necessarily. But overlap can build up quietly in the background if nobody is reviewing the bigger picture.

The ESG investment market has become crowded very quickly. There are now thousands of sustainable funds globally, all using slightly different language, methodologies, and investment approaches. Trying to compare them properly without guidance can become quite time-consuming.

Professional advice often helps narrow things down in a more practical way. Not just from a sustainability perspective, but from an overall financial planning angle as well. Because ultimately, sustainable investing still needs to function as part of a wider investment strategy. Risk, diversification, time horizon, retirement planning, tax efficiency — all the usual fundamentals still matter.

The ESG side is important. But it should work alongside the financial side, not replace it entirely.
