We are proud to celebrate the London Stock Exchange’s 2026 Green Economy Mark cohort, comprised of 95 companies and funds with a combined market capitalisation exceeding £192.4 billion. Since its inception in 2019, the cohort’s market capitalisation has more than tripled [Note 1], demonstrating the growing scale of the green economy in London’s capital markets.

The 2026 cohort demonstrates how companies and funds are delivering measurable real-world outcomes while creating long-term value. From reducing emissions to improving resource efficiency, these organisations are embedding environmental activity within their core commercial strategies.

Green Economy Mark report methodology

The Green Economy Mark is provided by the London Stock Exchange and draws upon LSEG's Green Revenues Classification System (GRCS), which identifies companies and funds providing green products and services which contribute towards environmental objectives. Revenues are classified based on the GRCS.

The GRCS captures environmental products and services across the whole equity value chain, covering 10 green sectors, 64 sub-sectors and 133 micro-sectors. The Green Revenues Data Model is used by LSEG to derive a percentage at the sector, sub-sector and micro-sector level for each company.

Each business activity defined by the GRCS is evaluated against seven environmental objectives:

  • Climate change mitigation
  • Climate change adaptation
  • Pollution prevention and control
  • Protection of healthy ecosystems
  • Sustainable use and protection of water and marine resources
  • Transition to a circular economy, waste prevention and recycling
  • Sustainable and efficient agriculture

This work is then turned into an overall strength of ‘greenness’, or net environmental impact, of companies’ activities and revenues into three tiers:

Tier 1 – Clear and significant environmental benefits
Tier 2 – Limited but net positive environmental benefits
Tier 3 – Some environmental benefits but are overall net neutral or negative

Companies with Tier 1 and 2 revenues can obtain the Green Economy Mark, highlighting that their products and services deliver net positive environmental benefits.

The Green Economy Mark identifies companies and funds on all segments of the Main Market and AIM that generate 50% or more of their total annual revenues from products and services that contribute to the global green economy, as defined by the above methodology. For pre-revenue companies, 100% of their business activity must be classified under Tier 1 and Tier 2 micro-sectors.

Any companies and funds may apply to have their green revenues considered for the Green Economy Mark via the Sustainable Finance team at the London Stock Exchange, the process is managed independently to the LSEG Green Revenues Data Model. Ahead of IPO, companies and funds may also apply to be provided the Green Economy Mark upon admission. Companies and funds have commented on the benefits of being able to talk about this on their investor roadshows.

[Music playing in the background.][Ross Grier, Lead Portfolio Manager, Next Energy Solar Fund] The green economy mark,means that investors can very quickly identify that the nextenergy solar fund, is a force for good in the economy.[Chris Dodwell, Global Lead of Policy & Advocacy Impax Asset Management] We're really proud to have held the mark since its inception.And because LSEG is such an internationally renowned brand,we really think it helps us,communicate our authenticity and our commitment to the green economy.[Roger Thornton, Director of Applications Engineering, Raspberry Pi] The green economy mark,is a symbol that. Raspberry Pi is building,products and a company that,embodies the principles of the green economy.Now that we're through our IPO process and we're now listed,we're going to be much more vocal about the fact that we have this mark.It's an independent statement of,actually what impact is all about.We've been operating as a specialist investor in thetransition to a sustainable economy for 26 years now.But it's nice that other people are recognizing that,rather than just us asserting it ourselves.We've known for a long time that the green component,of our economy is absolutely vital.What we want to see is a more sustainable future.The green economy itself is where capital, is going to beput to work to create that, better planet we're all seeking.Greenis invariably cheaper in the long run,and it's better for the world in the long run.We can't afford not to do this.So I think it's really important for companies likeImpax and for the green economy community that's been broughttogether by LSEG to be,advocates, for that change and to help shape the economy andto shape future markets.[Discover more about the Green Economy Mark from the London Stock Exchange] [londonstockexchange.com/GreenEconomyMark]
