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 while raising business results. ERI is an accredited partner of the Race to Zero, led by the United Nations 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 five pillars, as laid out in the Exponential Business Playbook: 1) cut operational emissions; 2) decarbonise value chains; 3) build and scale solutions; 4) mobilise finance and investment; and 5) shape policy and narrative. 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.

Commodity Certificates as a Necessary Mechanism to Scale Solutions and Decarbonise Hard-to-Abate Sectors
Commodity certificates can help unlock the investment needed to scale low-carbon solutions in hard-to-abate sectors such as steel, cement and chemicals. This article explores how they can bridge the gap between emerging supply and global demand, while outlining the infrastructure needed to build a credible, trusted market.
Beyond Consensus: The Business Imperative for a Post-Fossil Fuel Future
The climate conversation is shifting from whether we must phase out fossil fuels to how quickly we can deliver a fair transition. At London Climate Action Week, ERI and FFTI brought business, investors and civil society together to focus on implementation, with a clear call for policy certainty, market reform and coordinated corporate action to scale fossil-free solutions.
The Solutions-driven market infrastructure: Unlocking growth while driving system-wide transition
During a hot morning at London Climate Action Week 2026, Exponential Roadmap Initiative (ERI) and Adapteo Group convened a roundtable around a deceptively simple question: If many of the solutions needed for the transition are already commercially viable, technically credible and ready to scale, why are markets still moving too slowly to deliver 1.5°C-aligned transitions?
