Methodology
Climate50 is built from a rules-based framework designed to identify public companies with meaningful, core exposure to the climate economy.
Eligibility framework
A company may qualify if its business falls into at least one of three groups:
- Direct climate revenue: renewable power, energy storage, EVs, EV infrastructure, efficiency systems, or comparable climate solutions.
- Upstream enablers: essential climate-transition materials and components such as lithium, copper, rare earths, and nuclear fuel infrastructure.
- Climate infrastructure: builders and suppliers of the physical systems needed for electrification and decarbonization.
Greenwashing filter
Climate50 excludes companies where climate exposure is incidental, symbolic, or too small to drive the core economics of the business.
- No credit for simply consuming renewable power internally.
- No credit for vague sustainability language without core climate revenue.
- No inclusion for mixed-energy businesses where fossil exposure remains dominant.
