Exponential Roadmap Initiative members
Who we are
The Exponential Roadmap Initiative (ERI) is a collaborative climate initiative uniting companies that are innovators, disruptors and transformers to drive exponential action to halve emissions by 2030. ERI is an accredited partner of the Race to Zero, led by the High-Level Climate Champions. Our secretariat team is made up of business strategists and experts in greenhouse gas accounting, supply chain sustainability and climate communications.
What we do
We support leading companies to take radical climate action across four pillars, as laid out in the 1.5°C Business Playbook: 1) reducing own emissions; 2) reducing value chain emissions; 3) providing and scaling climate solutions; and 4) accelerating action in society. Our Climate Performance Review is a valuable tool that allows companies to identify key gaps and opportunities.
We work with our members to transform business models and develop and share best practices, eg in the 1.5°C Supply Chain Leaders. We provide open-source tools and resources that are regularly updated to reflect practices as they evolve. And we shape standards and frameworks with the aim to advance integrity and to provide thought leadership on credible corporate climate action.
Halving emissions,
Scaling solutions
The Exponential Roadmap Initiative (ERI) is founded around the Carbon Law, proposed by one of the world’s leading climate scientists, Johan Rockström, Co-chair of the Exponential Roadmap Initiative and its Co-founder, Owen Gaffney and others in Science Magazine in 2017. The Carbon Law is a global roadmap for halving carbon dioxide emissions every decade. This heuristic applies to all entities at all scales.
Showing that halving global carbon emissions by 2030 is possible, the Exponential Roadmap is a science-based, cross-sector collaboration that has resulted in a report published in three iterations. The report highlights 36 solutions with exponential scaling potential to halve global greenhouse gas emissions by 2030.
