GHG scopes included:

The high yield universe consists of both public and private entities of various sizes with GHG reporting more typical in the larger public companies. Current coverage is in the 80% range by market value and close to 55-60% by company. SKY Harbor uses ISS ESG for climate data and assessment. ISS ESG collects reported emission data if available and models some companies based on industry exposure for others. That said there are a number of companies that have no data currently and are excluded from ISS ESG portfolio level calculations. Nevertheless we feel the methodologies are sound and the comparative trends over periods are indicative of our actions.


Net Zero Investment Framework


We rely upon ISS ESG’s sectoral decarbonization approach (SDA) which is inspired by the SDA developed by the Science Based Targets initiative and is developed around the IEA scenarios, particularly the Sustainable Development Scenario (SDS), Stated Policy Scenario (STEPS) and Current Policy Scenario (CPS). The ISS-ESG scenario analysis combines the IEA scenarios with the SDA approach by allocating a carbon budget to a company based on its market share and the expected emissions trajectory associated with that sector. We use this information to provide input into the type of companies that can positively benefit the portfolios net zero ambitions over time, always taking into account the need for certain risk taking and the limited companies that currently contribute to the overall ambition.

Additional information

Proportion of AUM committed:

We have already transitioned every public fund where we manage and control the investment policy to Responsible Investment vehicles incorporating a net zero goal. We will continue to engage with our asset owner clients to advocate moving their portfolios to align with a net zero target over time.

Policy on coal and other fossil fuel investments:

Yes. We understand that most SBTi call for the phaseout of financial support to existing coal assets by 2030 and existing oil and gas assets by 2040. We have accelerated that time frame and already exclude thermal coal and oil and gas investments in our Responsible Investment Strategies, which currently comprises 53% of AUM.
