Sustainable and responsible Investment

Expert opinion

By George Latham

  • Sustainable and Responsible Investment (SRI) funds are increasingly popular and moving closer towards the mainstream.
  • Around £11 bn is invested in Britain's sustainable, responsible and ethical funds, with nearly 100 different mandates for retail investors1.
  • There is a growing focus on ‘solution providers’ – companies tackling social or environmental issues such as climate change.
  • Companies that pay attention to social and environmental issues appear to be better managed than those that don’t.


What does Sustainable and Responsible investing mean to you? Does it conjure up ideas of specialist funds with strict exclusion criteria, run by a manager content to work away in a small corner of the market and missing out on the big returns? Or does it seem more like the passing investment trend currently hitting the headlines because of a number of fund houses jumping onto the ‘green’ bandwagon?

Whatever your opinion, the facts are getting harder to ignore. Sustainable and Responsible Investment (SRI)2 funds are increasing their share of the investment market, especially in the UK, where according to Ethical Investment Research Services (EIRiS) there is now around £11 billion invested in Britain's green and ethical funds, divided among nearly 100 different SRI mandates for retail investors. What was previously seen as a relatively niche area for a few well intentioned investors is now clearly very big business. Despite this trend there has been a notable shift in the shape of the market for these funds over the last couple of years, with a number of smaller more focused boutiques springing up, and at the same time some of the larger more established players cutting resources dedicated to Sustainable and Responsible Investing.  Table 1 summarises the evolution of SRI, and highlights the different approaches available.

Table 1. Different SRI approaches:


  • Driven by ethical values
  • Focused on excluding certain types of activities using negative screens


  • Enabling differing standards of Corporate Responsibility
  • Focused on best-in-class social & environmental performance and financials


  • Enabled by the emergence of environmental and social issues as significant mainstream investment issues
  • Focused on investing in ‘solutions-providers’ 

From Moral Values to Investment Value

Recent developments, both in fund offering and client demand, have seen SRI funds explore more explicitly the link between sustainability and investment returns. We see a growing area of focus on so-called ‘solution providers’ – companies actively tackling challenging social or environmental issues such as climate change. Regulatory changes and shifts in consumer behaviour have created opportunities for the private sector to develop and scale up the technologies and services that can provide workable solutions such problems. The result has been the emergence of a range of funds aimed at financing new technologies, ranging from wind and wave power to businesses offering educational and healthcare services around the world. 

Some of these funds are unapologetically opportunistic; focusing simply on what companies do and largely ignoring the Environmental, Social and Governance (ESG) analysis of how they do it. Others funds choose to take a more holistic approach, demanding that those companies are operating and developing their businesses responsibly. This standpoint takes the logical – and pragmatic – view that companies developing renewable energy also need to be held to account for their actions. The IM WHEB Sustainability Fund aims to do precisely that. We have identified nine environmental and social themes which we believe represent diversified sources of growth, and as such we would expect them to outperform the market over the longer term.

Do SRI themes lead to better fund performance?

For SRI fund managers, as well as avoiding or prioritising certain types of companies, there has been a long-running debate about the financial performance of their funds. Critics argue that by limiting the range of companies that these funds can invest in, they also limit the returns that they can make. 

While initially this might seem to make sense, there is a solid body of evidence that finds the reverse. Rather, on balance, companies that pay attention to social and environmental issues appear to be better-managed companies than those that don’t. Limiting your universe, as critics had originally viewed SRI, looks like quite a good idea if you are effectively screening out companies that are badly managed.

More to the point, every fund manager, SRI-focused or mainstream, has exclusion criteria of their own (for example, whether they are looking for income or capital growth stocks), and chances are their list of companies in which they cannot or will not invest will be considerably longer than the list of companies in which they can invest. Each manager has to cut their cloth according to their particular investment mandate and under a particular set of constraints.

It could be argued that any mainstream fund managers worth their salt would look to actively avoid companies with a reputation for poor CSR, simply as a matter of good business sense. However,  until this more long-term approach is applied across all funds, those with an SRI slant look to be setting the investment trend by rewarding better governance and increased responsibility from companies by directing investment in their direction.

SRI as a strategy for long-term investment

There are a number of reasons why SRI and long-termism should be natural bedfellows. Firstly, to incorporate an analysis of environmental, social and governance (ESG) factors into investment decision-making requires an inherently long-term outlook. SRI investors are keen to have a deeper understanding of how the companies they invest in are managed, and how management can ensure that the growth profile and returns generated are sustainable over time. Secondly, SRI investors often apply a research-intensive approach to understand key themes influencing the direction and shape of future economic development, which hopefully will enable investors to identify those companies that are more likely to succeed over time.

Through a long-term and active ownership approach SRI investors are better able to exercise stewardship over their investment holdings. Over time managers are able to develop a deeper understanding of an industry and a company’s position within that, through building a consistent relationship with company management.

The outlook for SRI is positive

SRI funds have grown greatly in popularity over the last few years, as companies with an active focus on environmental issues have benefited from growing political and consumer support. However, the financial crisis of the last few years has brought an altogether more turbulent market, and clean-tech and other SRI funds have not remained immune to the downturn. But even so, the outlook remains promising. New legislation – focusing in particular on climate change, but also championing social issues such as healthcare and product safety – continues to be developed in the UK, EU, US and beyond, serving to provide continued good news for investors in these sectors. What is clear is that the SRI investment sphere will continue to evolve at a rapid pace, which can only be a good thing for investors, and for society as a whole.
