How do I invest in sustainable or socially responsible companies?

Socially responsible investing (SRI) is becoming increasingly popular. The idea is that ecologically and socially responsible management makes a company sustainable and ensures sustainable returns on investment.

There are several indices available to invest socially responsible with ETFs. These may differ considerably in terms of their general approach so that not all indices are equally well suited to you and your personal and ethical objectives.

For example, climate change indices focus on fulfilling regulatory requirements to reduce greenhouse gases, which makes the corresponding ETFs highly sought after by institutional investors. By contrast, indices on electric mobility, clean energy and water are particularly interesting for investors who want to achieve outperformance with thematic investments in megatrends.

That also leaves an important space for ETFs and indices that have a broader scope and typically use more stringent selection criteria. Such indices are a good fit for investors with ethical and ecological convictions. In the following, we describe the differences between the various wide-ranging sustainable indices and rank the best available ETFs on Europe for you.

STOXX SRI indices

The STOXX SRI indices aim for the companies with the highest environmental, social and governance (ESG) rated performance from each sector of the parent index and target a 33% representation of each sector’s market cap. The companies with the highest emission intensity in the parent index are excluded. Based on data from the ESG rating company Sustainalytics, STOXX SRI indices also exclude companies involved in the production of weapons, alcohol, tobacco, gambling, adult entertainment, oil and gas, nuclear power, or thermal coal and companies that violate the principles of the United Nations Global Compact. The remaining securities are weighted by their free float-adjusted market capitalisation.

Methodology of the STOXX SRI indices

• based on their respective regional parent index
• best-in-class approach – the indices select the 33% highest ESG-rated companies in each sector of the parent index
• excluded sectors and companies: weapons, alcohol, tobacco, gambling, adult entertainment, oil and gas, nuclear power, thermal coal, non-compliance with UN Global Compact, highest emission intensity in parent index
• weighted by float-adjusted market capitalisation

Dow Jones Sustainability indices

Dow Jones Sustainability indices are designed to measure the stock performance of the leading sustainable companies of their respective region, identified by the investment company RobecoSAM through an annual corporate sustainability assessment. The indices represent their respective portion of the global parent index. The index excludes companies that generate revenue from nuclear energy, alcohol, tobacco, gambling, armaments and firearms, and/or adult entertainment.

Methodology of the Dow Jones Sustainability indices Factsheet Methodology

• reassessment takes place annually in September
• selection of stocks depends on RobecoSAM rating

The FTSE ESG Low Carbon Select indices aim to reduce carbon emissions and fossil fuel consumption by 50% each and to improve the ESG rating by 20%, compared to the respective parent index. Companies that are involved in weapons, tobacco, thermal coal, nuclear power or that violate the principles of the UN Global Compact are generally excluded.

Methodology of the FTSE ESG Low Carbon Select indices Factsheet Methodology

• general exclusions as well as exclusions via an optimisation scheme
• generally excluded sectors and companies: weapons, tobacco, thermal coal, nuclear power, non-compliance with UN Global Compact
• climate protection target: reduction of carbon emissions and fossil fuel consumption by 50% (compared to parent index)
• ESG target: improvement of ESG rating by 20% (compared to parent index)

MSCI Climate Change ESG Select indices

The MSCI Climate Change ESG Select indices evaluate and weight companies from the respective parent index by their impact on climate change. Companies are assessed according to their carbon emissions and climate-friendly companies are given greater weighting in the index. An additional ESG filter excludes companies that are involved in controversial weapons, tobacco, thermal coal, unconventional oil and gas production or nuclear power or that violate the standards of the UN Global Compact.

Methodology of the MSCI Climate Change ESG Select indices

• based on their respective regional parent index
• titles are weighted according to their impact on climate change: climate-friendly companies are given a greater weight
• index is reviewed semi-annually (not in parallel with parent index)
• excluded sectors and companies: controversial weapons, tobacco, thermal coal, unconventional oil and gas production, nuclear power, non-compliance with UN Global Compact

MSCI ESG Enhanced Focus CTB indices

The MSCI ESG Enhanced Focus CTB indices are characterised by low cost and broad market coverage. These benefits result from a rather straightforward ESG-scanning method. Rather than evaluating companies individually, the MSCI ESG Enhanced Focus CTB indices simply exclude certain sectors and firms. This applies to companies that produce weapons, thermal coal or tobacco or that violate the principles of the UN Global Compact. The indices are designed to maximise exposure to positive ESG factors while reducing the carbon equivalent exposure to carbon dioxide and other greenhouse gases as well as their exposure to potential emissions risk of fossil fuel reserves by 30% (compared to the parent index). Positive ESG exposure is achieved via optimisation of the index construction: companies with high (low) ESG Ratings are over-weighted (under-weighted).

Methodology of the MSCI ESG Enhanced Focus CTB indices Factsheet Methodology

• based on their respective regional parent index
• weighted by ESG-criteria: over-weight (under-weight) companies with high (low) ESG Ratings
• target 30% reduction in carbon exposure compared with parent index
• excluded sectors and companies: weapons, thermal coal, tobacco, non-compliance with UN Global Compact

MSCI ESG Leaders indices

The MSCI ESG Leaders indices aim for companies that have the highest environmental, social and governance (ESG) rated performance in each sector of the parent index while excluding companies involved in severe controversies. The MSCI ESG Leaders indices target a 50% sector representation vs. the parent index. Sub-indices belonging to the MSCI Select ESG Rating and Trend Leaders series rate companies not only on the basis of their current ESG profile but also according to how that profile develops over time. Companies which are involved in weapons, alcohol, gambling, tobacco or nuclear power are generally excluded. The same applies to companies that do not comply with the principles of the UN Global Compact. The selected securities are weighted by their free float-adjusted market capitalisation.

Methodology of the MSCI ESG Leaders indices

• based on their respective regional parent index
• best-in-class approach – the indices select the 50% highest ESG-rated companies in each sector of the parent index
• excluded sectors and companies: weapons, alcohol, gambling, tobacco, nuclear power, non-compliance with UN Global Compact
• MSCI Select ESG Rating and Trend Leaders indices take into account not only the ESG profile itself but also its development
• weighted by float-adjusted market capitalisation

MSCI Screened indices

The MSCI Screened indices are characterised by low cost and broad market coverage. These benefits result from a fairly straightforward ESG-scanning method. Rather than evaluating companies individually, the MSCI Screened indices incorporate exclusions of specific sectors as a whole. Companies that are involved in weapons, tobacco, thermal coal, or oil sands are excluded from the indices. Furthermore, companies that fail to comply with the United Nations Global Compact principles are excluded. The remaining securities are weighted by their float-adjusted market capitalisation.

Methodology of the MSCI Screened indices

• based on their respective regional parent index
• weighted by float-adjusted market capitalisation
• excluded sectors and companies: weapons, tobacco, thermal coal, oil sands, non-compliance with UN Global Compact

MSCI ESG Universal indices

The MSCI ESG Universal indices are characterised by low cost and broad market coverage. These benefits result from a fairly straightforward ESG-scanning method. By default, the MSCI ESG Universal indices exclude only companies found to be in violation of international norms as defined by the UN Global Compact (e.g., facing very severe controversies related to human rights, labour rights or the environment) and companies involved in controversial weapons. Some sub-indices add further controversial sectors to this spectrum. The MSCI ESG Universal indices enhance exposure to companies which feature both a high ESG Rating and a positive ESG trend over the most recent 12 months by increasing the weight of these companies. By contrast, the weightings of companies who lag behind their industry peers in terms of ESG quality are reduced.

Methodology of the MSCI ESG Universal indices Factsheet Methodology

• based on their respective regional parent index
• weighted by ESG-criteria: over-weight (under-weight) companies with high (low) ESG Ratings
• ESG-related improvements by companies are taken into account
• exclusion of companies that fail to comply with the UN Global Compact or that are involved in controversial weapons
• some sub-indices feature additional exclusions

MSCI SRI indices

The MSCI SRI indices aim for companies that have the highest environmental, social and governance (ESG) rated performance in each sector of the parent index and target a 25% representation of each sector’s market cap. Companies whose products have negative social or environmental impacts and companies associated with severe controversies are excluded. This applies to companies that are involved in weapons, adult entertainment, alcohol, tobacco, gambling, genetically modified organisms, nuclear power, or thermal coal. Companies that fail to comply with the UN Global Compact principles are excluded as well. Accordingly, the SRI series features the strictest exclusion criteria of all socially responsible MSCI indices. Some sub-indices further tighten the selection criteria with regard to climate protection (S-Series, Low Carbon SRI Leaders, SRI Select Reduced Fossil Fuels). The selected securities are weighted by their free float-adjusted market capitalization.

Methodology of the MSCI SRI indices

• based on their respective regional parent index
• best-in-class approach – the indices select the 25% highest ESG-rated companies in each sector of the parent index
• excluded sectors and companies: weapons, adult entertainment, alcohol, tobacco, gambling, genetically modified organisms, nuclear power, thermal coal, non-compliance with UN Global Compact
• strictest exclusion criteria of all socially responsible MSCI indices
• some sub-indices feature additional selection criteria with regard to climate protection (S-Series, Low Carbon SRI Leaders, SRI Select Reduced Fossil Fuels).
• weighted by float-adjusted market capitalisation

Solactive Core indices

The Solactive Core indices are based on their respective regional parent index from the Solactive Global Benchmark Series but feature additional ESG-related exclusions. Companies that are involved in the production of controversial weapons or that have violated the principles of the UN Global Compact over a period of three years are excluded. The same applies to pure coal mining companies. The Solactive Core indices are characterised by very low cost, which is achieved by the relatively simple method of ESG implementation. The selected securities are weighted by their free float-adjusted market capitalisation.

Methodology of the Solactive Core indices Factsheet Methodology

• index adjustment takes place quarterly in February, May, August and November
• excluded sectors and companies: controversial weapons, pure coal mining, non-compliance with UN Global Compact
• weighted by float-adjusted market capitalisation
