The green economy has surpassed US$10 trillion despite energy shocks, policy divergence and market volatility.

Against a backdrop of volatile markets, energy supply disruption and rising electricity demand, our ‘Investing in the green economy’ report continues to analyse green investment opportunities and how the green transition is evolving by examining the size, growth, performance and financing of the global green economy across asset classes.

Within the report we also examined how green assets are scaled via merger & acquisition (M&A) with profitability analysis, the role of green bonds in supporting capital flows, and the diverging regional green economy shaped by decarbonisation and energy security priorities.

US$10 trillion milestone

The green economy surpasses US$10 trillion market capitalisation for the first time

Green M&A reaches scale

Read our seventh annual ‘Investing in the Green Economy’ report to:

  • Gain data-driven insights into the global growth trajectory and performance of the green economy 
  • Understand key geographic and sector-level trends shaping green investment opportunities
  • Access valuable analysis on green mergers and acquisitions, an increasingly important market for scaling green businesses and technologies

Why is this research important?

  • Identifying green investment opportunities requires trusted data and insights. At LSEG, we have been developing proprietary data, analytics and indices to measure company exposure to the green economy since 2008. This report shows those solutions at work.
  • As M&A is becoming a key mechanism for scaling green assets, this report for the first time examined green deals by leveraging the Green Revenues data in combination with Deals data covering 1.5 million M&A transactions.
What we are seeing is the emergence of the green economy as a core driver of global growth – a US$10 trillion opportunity, supported by broad-based revenue expansion, strong long-term performance, and deepening capital markets.

What is the green economy?

The green economy consists of companies that provide products and services with environmental benefits – from renewable energy and clean water to energy-efficient buildings and recycling services. These solutions – diverse across value chains, industries and markets – address climate change as well as broader environmental challenges.
