Every holding in a portfolio implies a warming trajectory. The S&P 500’s implied Global Warming Potential (GWP) is 4.1°C — well above the Paris Agreement’s 1.5°C target. This guide explains how Ziggma measures GWP at the holding level and aggregates it to a portfolio temperature score, and how self-directed investors can reduce that number significantly without exiting public equities.
The full guide is coming soon. In the meantime, the Ziggma Impact Investing Guide covers portfolio temperature alignment alongside all other public-market impact strategies.
