CCBJ estimated the global climate change industry at $3.59 trillion in 2024, up 14% from 2023. Adaptation & Resilience accounted for $34.6 billion, or 1% of total global climate-industry revenues, compared with hundreds of billions of dollars each in renewable power, efficiency, green buildings and more than $1.6 trillion in transportation as the largest segment (as quantified in the Q2 2026 edition of CCBJ).

CCBJ characterizes the state of climate change finance and investment at the end of 2025 as governments, utilities, industry, commercial enterprises, and financiers face an uncertain policy environment.

The annual Climate Change Business Journal Business Achievement Awards recognize innovation, commitment, outstanding performance, project planning, execution or key accomplishments and milestones in 2024. Climate change industry players need resilience as market factors and policy inaction conspire to make business challenging, but leaders and innovators prepare for 2025-2026.

The Energy Transition is not a linear process, and the climate change industry continues to operate in multiple layers of energy production, storage, distribution and efficient consumption, as well as the legacy issues. The promise of hydrogen as the simplest of molecules and perhaps the most challenging and perplexing of energy carriers has the clean energy world diving into hydrogen applications across all major energy categories.

Climate Change Business Journal® assesses where we are in the energy transition in 2023 with a review of U.S. government energy and emissions data and forecasts, comparing business as usual with long-term net zero strategies.
