Investing in oceans and marine life | Credit Suisse

The investment case for the blue economy

Ocean health is vital to human life on earth. Marine ecosystems also play a critical role in the global economy. We believe that a sustainable blue economy also makes good business sense. As a bank, we are committed to supporting the world’s oceans through finding new ways to finance the UN SDG 14 ‘Life Below Water’.

Did you know?


Globally, the market value of marine and coastal resources and industries, is estimated at USD 3 trillion per year or about 5% of global GDP. 


The world’s oceans are precious resources, because they support so many industries and coastal communities. Climate change and the unsustainable use of marine resources are harming the health of the oceans. This puts ocean-related businesses at risk as well as those whose livelihoods depend on them. However, marine ecosystems can also offer investment opportunities. 

Why protecting and investing in ocean makes sense

One mature whale sequesters more carbon than 30,000 trees.

Oceans absorb 93% of climate heat.

Oceans generate 50% of our oxygen.

Oceans absorb 25% of carbon emissions.

Why it’s time for investor action on ocean health

The challenge of financing UN SDG 14 – Life under water

Every year, ocean pollution and exploitation add up to many billions of dollars of economic loss and harm to the natural world.

Its main targets are:

  • Reduce ocean acidification and pollution of all kinds
  • Restore ocean ecosystems
  • Support sustainable fisheries
  • End overfishing
