Should businesses prioritize long-term climate risk strategy over immediate financial returns?
Global clean energy investment totaled $2.3 trillion in 2025, marking an 8% increase from the prior year. This record growth occurred as industry leaders gathered at the Emerald Summit to discuss the integration of climate risk into business operations.
Why it matters
The summit sought to reconcile the contrast between record financial commitments and public polling showing that 62% of Americans doubt sufficient climate action will take place. This disconnect highlights the evolving focus on how capital markets evaluate long-term climate tech opportunities.
Global energy transition investment grew 8% year-over-year to hit $2.3 trillion in 2025. Meanwhile, public pessimism has risen nine percentage points since 2022, despite the existence of approximately 78,000 climate tech startups in the United States.
