Our minimum ESG investment standards form the basis of our asset management approach, which is implemented for you by Warburg Bank’s portfolio management team. Companies and sovereigns that do not meet our minimum environmental, social and ethical requirements are excluded from the investable universe.
Shares and bonds issued by companies that, for example, generate revenue from banned weapons or are involved in serious corporate controversies are excluded. Such controversies involve severe misconduct in environmental, social or corporate governance matters. Companies that exceed defined revenue thresholds for thermal coal mining or coal-fired power generation are also excluded. We take issuers’ carbon metrics into account in the selection process.
For sovereign issuers, we consider three ESG criteria that may result in the exclusion of their bonds from our investment universe. Sovereign issuers are excluded if they have neither ratified nor initiated the implementation of the two fundamental UN agreements: the International Covenant on Civil and Political Rights and the United Nations Convention against Corruption. In addition, each country must have an MSCI ESG Research rating of at least B to remain in the investable universe.
The Warburg Group’s ESG Investment Committee brings together the ESG expertise of our ESG Management team, Warburg Bank’s portfolio management team, Warburg Invest and Marcard, Stein & Co. The Committee continuously reviews all exclusions and adjusts them where necessary. To make well-founded assessments of the severity of controversies, we engage in active dialogue with selected companies.
Our portfolio management team assesses the ESG profile of a country or company using, among other factors, the MSCI ESG Rating. It combines environmental, social and governance factors into a rating on a scale from AAA to CCC. Countries and companies rated below BBB are excluded from the ESG investment universe.
The assessment of countries is based on twelve criteria. We refer to globally recognised institutions such as Freedom House, the UN or Transparency International. Important criteria are climate protection, corruption, money laundering, military expenditure and the death penalty.
Our ESG methodology for selecting companies follows a multi-stage process. Absolute and relative exclusion criteria for business activities are combined with minimum rating thresholds and quality standards for addressing corporate controversies. The exclusion criteria apply to controversial business activities, including alcohol, tobacco, weapons and nuclear energy. Companies with an MSCI ESG Research rating below BBB — and therefore a significantly weaker ESG profile than their industry peers — are also excluded. We likewise do not invest in companies that violate recognised standards such as the UN Global Compact.
Greenhouse gas emissions are a key consideration in our investment process, as they contribute to global warming, rising sea levels and more extreme weather conditions. From an economic perspective, high carbon emissions may result in higher regulatory costs and even impairments if certain business activities become unprofitable or are prohibited. However, our objective is not simply to exclude companies with high carbon intensity, as these companies may have the greatest potential to reduce emissions if they take appropriate action. We therefore combine carbon intensity with the MSCI Carbon Emissions Management Score. This score indicates whether a company’s management has recognised carbon emissions as an issue and established processes to avoid or reduce them. This allows us to consider companies that currently report high emissions but can demonstrate that they are working effectively to reduce them as potential investments.
Our focused ESG strategy takes the principal adverse impacts on environmental, social and governance factors into account. We also aim to maintain a minimum proportion of investments that meet the applicable SFDR criteria. For positions classified under the SFDR definition, we disclose the definition applied, the assessment methodology and the impact indicators used. We show our clients the environmental, social and governance characteristics of their managed assets in supplementary overviews integrated into our regular reporting.
A significant risk when investing with ESG criteria is so-called “greenwashing”, which involves making misleading or unsubstantiated claims about the environmental or social characteristics of investments. To reduce greenwashing risks, we apply documented selection criteria as well as internal review, approval and updating processes.
Investments in securities that comply with ESG criteria are also subject to risk. Nevertheless, in our view, there are compelling reasons to incorporate ESG criteria, and a growing number of investors are doing so. This is not a short-term trend, but a fundamental shift in investor behaviour.
One important aspect is that many investors want to understand the environmental and social characteristics of their investments and take them into account when making investment decisions. We are happy to support them in doing so.
