Data: Energy Impact Partners; Chart: Axios VisualsThe VC firm Energy Impact Partners has created an index that tracks performance of companies spanning a wide range of climate-friendly technologies — and it shows they're crushing the broader market.Why it matters: The firm's new "Climate Tech Index" differs from technology indices that are more narrowly targeted, such as only tracking clean energy companies.Get market news worthy of your time with Axios Markets.

Instead it's a tool for tracking the aggregate performance of a suite of new market entrants and more established players.On the mobility side, various companies range from incumbent electric cars leader Tesla to recent arrivals like Canoo, which is among the many EV startups that recently went public via merging with a special purpose acquisition company.Others include renewables companies like First Solar and wind turbine heavyweight Vestas, the plant protein company Beyond Meat, the hydrogen fuel cell company Plug Power, and the advanced battery firm Quantumscape.The intrigue: TechCrunch's coverage by Jonathan Shieber makes an interesting point..."While the EIP list is intended to be informative, there’s no reason someone couldn’t take this index and turn it into an exchange traded fund for the industry."More from Axios: Sign up to get the latest market trends with Axios Markets.
