For the first time in history, global investment in clean energy has surpassed fossil fuels.
In 2025 alone, more than $2.2 trillion will be invested in clean energy, efficiency, and electrification globally, according to the International Energy Agency’s (IEA) World Energy Investment report. That’s roughly two-thirds of the total global energy investment expected this year.
Yet even this unprecedented momentum isn’t enough to meet global climate goals. The IEA estimates that to stay on track, investment in renewables must double, and energy efficiency and electrification must nearly triple. Demand is surging—and the appetite for continued investment is only growing.

Let’s look at the full scope of the Ocean Economy.
The global ocean economy––valued at approximately $1.5 trillion as of late 2024––could grow to over $3 trillion by 2030, according to the London School of Economics and Political Science. Key growth sectors include offshore wind, marine aquaculture, and fish processing.
Why? Because the world’s economy is built on the ocean.
- Over 80% of global trade (by volume) is transported by sea.
- The ocean supports 500 million people through employment in small-scale fisheries and related jobs alone.
- More than 3 billion people depend on it for food security.
Beyond its economic value, the ocean also plays a critical climate role by absorbing CO2 emissions, capturing excess heat, and generating oxygen.
We can’t survive without the ocean. We need it for food, climate regulation, and to host critical marine infrastructure. And in return, it demands nature-positive and sustainable development and technology to safeguard it from further degradation.
Companies across the globe are already paying attention to this need as they witness the impact of climate change on food production, the environment, and aging physical infrastructure.
Businesses are engaging with nature like never before. Investor interest is accelerating as financing solutions mature, policy barriers ease, and investable ocean innovations mature. Overall, stakeholders are recognizing the ocean as a high-growth investment sector—and the time to get involved is now.
