Ethical vs ESG: Can You Teach An Old Dog New Tricks?

 By contrast, Timeline (formerly Betafolio) ESG aims to allocate more to companies that adhere to higher sustainability standards and less to those that don’t, while maintaining our low-cost, buy-and-hold and globally diversified approach that has been demonstrated to serve investors well over the longer term.

Often this approach is referred to as “light green” ESG investing. Yet it is borne out of the acceptance that ESG investing isn’t black-and-white. It is more of a balancing act. Since environmental business practices can vary considerably among companies, corporate governance and practices that advance sustainability are better characterised along a spectrum. We believe that an investment methodology that applies more robust sustainability scoring at company level, rather than a blanket ban on an industry or sector, may better serve investors.

The United Nations describes sustainable development as

Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. (1989)

Whereas traditional financial analysis considers only quantitative financial and economic data, Environmental, Social and Governance investing attempts to incorporate non-financial factors into the investment decision making process. The goal of Betafolio’s ESG portfolio range is to place greater emphasis on companies that are adhering to higher sustainability standards while maintaining our low cost, buy-and-hold and globally diversified approach that has been demonstrated to serve investors well in the long term.

Fund managers use a variety of techniques in order to construct ESG portfolios. The more rudimentary construction methods involve excluding firms based upon their participation in the production of certain products, for example, munitions and tobacco. More complex construction methods include the use of ESG ratings in conjunction with share indexes, whereby a certain percentage of the lowest scoring firms are either removed or are weighted less heavily within the fund than their market capitalisation within the share index would suggest.

While ESG investing for equities is widely established, it is less so for fixed income.

The Betafolio ESG range was upgraded in early 2020 with the addition of a sustainable fixed income fund. Previously, this was not possible due to the minimal amount of funds in this space along with their high costs - this did not fit in with our low-cost philosophy.

The new Dimensional Global Sustainability Fixed Income Fund takes sustainability considerations into account through a combination of fund-level exclusions and sector-level weighting designed to reduce exposure to bonds issued by companies with less sustainable business practices. Issuers are ranked by an environmental score based on greenhouse gas emissions intensity, land use and biodiversity, toxic spills and releases, operational waste, and water management. The lowest-scoring issuers are generally excluded from investment. It also considers that some issuers are not high greenhouse gas emitters but may enable future emissions by selling fossil fuel reserves for consumption. Generally, issuers with the highest potential emissions from reserves are excluded.

Betafolio’s ESG portfolio range includes a number of ESG funds, included after a thorough analysis of the underlying fund construction process utilised to ensure their ESG credentials. In addition, all funds fit Betafolio’s core investment philosophy of being low-cost, passively managed and maintain a diversified market capital approach.
