Materiality-Weighted Portfolio Carbon Footprint
Preview
The total carbon footprint of a portfolio has commonly been used both as a measure of that portfolio’s climate impact and as a measure of transition risk. However, we found that impact and risk measurement may require different approaches. A tonne of CO2 has the same impact on our climate no matter where or how it's emitted. But when it comes to a company's transition risk, not all emissions are created equal. Some emissions matter more, depending on where they come from and the industry context. We found that investors could get a better signal by focusing on a materiality-weighted carbon footprint.
Our analysis shows that, over the past decade, emissions-based transition risk has had a stronger relationship with corporate earnings, stock performance and credit risk than previous academic studies suggested.

Financing the Climate Transition
Historically, climate investing has focused on portfolio decarbonization, but investors are increasingly turning to a “finance-the-transition” approach, seeking to invest in transition opportunities. The two approaches are not exclusive and best used hand in hand.
