TechMarketView’s comprehensive Sustainability Technology Activity Index (STAI) is our unique take on the sustainability technology landscape. The Index analyses how emerging and enabling technologies are being deployed (in the UK and worldwide) across a range of environmental sustainability use case areas.

The Index captures data about project milestones, partner involvement, major customer wins, and product launches - spanning activities from ESG reporting and nature monitoring to supply chain innovations and carbon removal. We rank the most active suppliers, common use cases, and deployed technologies, providing key trends for both suppliers and technology user organisations.

Sustainability Technology Activity Index 2025

The 2025 edition of the Sustainability Technology Activity Index tracks over 900 milestone activities from 2,000+ organisations worldwide, revealing which suppliers are genuinely delivering impact versus those merely making claims. This year's research exposes a surprisingly fragmented market where even Microsoft, the top-ranked supplier, accounts for just a fraction of total activity, signalling significant opportunities for specialists and new entrants.

Whether you're a technology supplier seeking competitive intelligence and market opportunities or a technology user evaluating solutions and suppliers, the Index provides the evidence base for strategic decision-making in this rapidly evolving landscape.

The global view

This flagship report reveals how sustainability technology is transitioning from peripheral concern to core business imperative, with analytics appearing in nearly two-thirds of all initiatives as organisations move beyond measurement towards actionable intelligence.

The research exposes significant opportunities across sectors, with technology combinations and strategic partnerships driving demonstrable results from pilot launches to scaled production deployments.

The UK view

The UK market analysis exposes distinctive domestic strengths in supply chain optimisation (ranking third nationally versus eleventh globally) and water management, reflecting Brexit-driven restructuring and growing Scope 3 emissions focus. However, with 73.5% of UK suppliers managing just one sustainability activity, the research reveals critical market fragmentation that presents both consolidation opportunities and integration challenges for organisations seeking comprehensive solutions.

taxonomy

The Index employs a unique taxonomy that categorises sustainability initiatives across diverse domains - from GreenTech and AgriTech to FinTech and PropTech.

Rather than focusing on niche manufacturing technologies, our methodology examines how emerging and enabling technologies serve as essential tools for environmental sustainability, allowing us to identify and analyse the most impactful technological contributions to global sustainability efforts.
