"We have been careless with our ocean for a long time," Schraven begins. "Waste has been dumped into the sea for a long time and continues to happen in some places, and there is a lot of pollution. We have also been using the resources from the sea for many years. The sea seemed like an inexhaustible source of income, especially for fishermen. For many people, the impact on marine life has remained out of sight. While the discussion about sustainability started and mainly concerned our society on land, the well-being of the ocean lagged behind in attention and urgency."
Ezrah Schraven is part of the Biodiversity & Nature team at PwC. As a specialist in marine resources, she closely monitors the global conference, but from the perspective of marine life. She states that the ocean has received little attention for a long time, partly because it is a distant concern for many people. "In our daily lives, we are rarely confronted with what is happening on and under the water. There is too little general knowledge about the connection between the quality of our daily lives and the role the ocean plays in it. We should treat our ocean with much more care."

During Cop16 in Cali, the focus is on biodiversity in the oceans. On this topic, we still know very little. 'The species richness in the ocean is immense, but the estimate is that we have only mapped about ten percent of it.'
The importance of (sea)water goes far beyond just biodiversity, Schraven explains. 'A healthy ocean encompasses important ecosystems and plays a crucial role in our climate, weather patterns, and even the composition of the air we breathe. More than seventy percent of our planet is ocean. The role that oceans play is enormous. And despite their size, they are vulnerable and sensitive to human activities.'
A healthy ocean provides us with 'ecosystem services'; services that cost nothing (except for good care), but from which we benefit greatly. These services include food, materials for new medications, innovation, the absorption of CO2, and the regulation of temperature, even on land. The loss of these services brings enormous risks and costs, even from a business-economic perspective.
'Take coral reefs and mangroves, for example. Both serve as a nursery for the sea and also as an important food source for marine life. They are therefore important for the fish population, which benefits the fishing industry. Mangroves and coral reefs also act as a natural buffer, providing protection to communities and businesses along the coast against waves, storms, erosion, and flooding. Without coral reefs and mangroves, both the fishing sector and coastal areas would face significant challenges.'
"As a leader in sustainable business practices, you are appealing to customers, it is a driver for innovation, helps with your existence, and increasingly also for financing opportunities."
Ezrah Schravenbiodiversity specialist, PwC the NetherlandsWhen biodiversity disappears, you also lose the source for possible future innovation and medication. The value of biodiversity and ecosystem services is increasingly recognized and visible in legislation and regulations, such as within the CSRD E3. Although the regulation of marine life within Dutch companies is still often and wrongly considered 'not relevant'. But the topic is gaining momentum, and with that comes awareness and an increase in reporting by companies.
In CSRD sustainability reporting, the ESRS E3 standard (water and marine resources) specifically focuses on water management and the protection of marine resources, and requires companies to transparently report on their use and impact on water and marine ecosystems.
ESRS E3 focuses on the sustainable use of water and the preservation of marine resources. The key elements of this measure are:
Companies are therefore responsible for reducing their impact on biodiversity. "This is not only important to the planet, but also essential for companies in the present, including their existence, which is increasingly dependent on their ecological footprint," says Schraven.
According to the biodiversity specialist, this challenge also presents opportunities. "For sure, because if you are a leader in sustainable business practices, you are attractive to customers, it drives innovation, helps with your existence and reputation, and increasingly also for financing opportunities. In short, it increases your resilience as a company."
Taking care the environment in a sustainable way also means that ecosystems can continue to provide the mentioned 'services', and sometimes these can even increase. Many industries depend on this supply. Think of more fish, clean water, clean air, a predictable climate, mild weather conditions, and little damage from disasters.
According to Schraven, expertise and caring about biodiversity are extremely important. "The more we understand biodiversity, the role of different species within ecosystems, and how this relates to everything that makes the Earth habitable, the better we can shape our societies and business operations in a way that is responsible for current and future generations."
