What does net-zero mean for your organization or sector? Quickly understand your organization or investment/lending portfolio’s path to adhering to the 1.5C or 2C scenarios set out by the Paris Agreement following the Science-Based Targets Initiative’s (SBTi) Temperature Scoring Method which was developed in collaboration with CDP and WWF.
Aligning to the Paris Agreement Warming Trajectory scenarios is critical for your organization’s disclosure and target setting. By incorporating the open-source CDP-WWF temperature rating methodology, Persefoni enables users to quickly understand the target year to achieve net-zero under every scenario for individual companies as well as across investment portfolios.
Persefoni uses a three step methodology for modeling across all use-cases: a target protocol, which converts individual emissions targets to temperatures; a company protocol, which aggregates these targets into an overall company score; and a portfolio protocol, which weights these company scores across an investment portfolio.
To convert individual emissions targets into temperatures, the target protocol uses the best available scientific climate scenarios from the IPCC Special Report on 1.5°C scenario database. It generates simple regression models for estimated warming in 2100 from climate scenarios with short, medium, and long-term trends in absolute emissions or emissions intensities.
At the portfolio level, company scores are weighted to assess an index or portfolio of companies, such as in the context of financial portfolios. In the event a company does not have relevant, publicly-disclosed emissions targets, it’s assigned a default temperature score which assumes a business-as-usual temperature.
