What is Implied Temperature Rise?

Our Implied Temperature Rise (ITR) metric is part of a powerful suite of analytical tools designed to help you build climate-resilient portfolios throughout the investment process. The intuitive, forward-looking metric, expressed in degrees Celsius, is built to show the temperature alignment of companies, portfolios and funds with global temperature goals.

With its coverage of over 12,000 issuers, Implied Temperature Rise supports reporting in line with evolving disclosure requirements.1 Investors can use the metric to set decarbonization targets, support engagement on climate risk and facilitate reporting aligned with the Internatioal Sustainability Standards Board (ISSB) and other industry standards.

How Implied Temperature Rise works

Implied Temperature Rise compares the current and projected GHG emissions of a broad universe of publicly listed companies across all emissions scopes (based on the company’s track record and stated reduction targets) with its share of the remaining global carbon budget for keeping warming this century to well below 1.5°C.

A company projected to emit carbon below budget can be said to “undershoot” the budget; a company projected to exceed the budget “overshoots” it.

The portfolio-level ITR compares the sum of projected GHG emissions against the sum of carbon budgets for the underlying constituents or holdings.

We determine ITR by:

1. Calculating a sector-specific carbon budget in metric tons of CO2e that the company can emit to be aligned with a pathway for limiting global warming to 1.5˚C.

2. Projecting the company’s future emissions through 2050 based on current emissions and reported emissions-reduction targets.2

3. Converting the company’s relative carbon budget over- or undershoot to an ITR, expressed in degrees Celsius.
