Environment

Stolt-Nielsen is committed to minimising the impact our operations have on the environment. From cutting emissions and conserving water to managing energy consumption, reducing waste and caring for the communities in which we operate, we approach environmental protection with creativity and commitment.

As a leader in bulk liquid logistics and distribution, and sustainable aquaculture, we understand that we have a responsibility to set far-reaching environmental ambitions across our operations. Our customers, business partners, employees and the communities in which we operate expect us to demonstrate our commitment to protecting our planet in everything we do. And, as regulations increase, we constantly review our policies and processes to ensure we continue to meet regulatory requirements and, in many cases, exceed them.

Stolt Sea Farm facilities use certified renewable electricity with 100% of electricity used in our Iceland operations certified renewable.

1. Stolt Tankers uses the Annual Efficiency Ratio (AER) to measure the intensity of its carbon emissions. This measures carbon emissions relative to a ship’s capacity
and distance travelled.

2. Includes wholly owned terminals only.

3. Includes wholly owned depots only.

4. Data is calculated using EcotransIt data measurement tools, which follow the international accepted GLEC framework, ISO 14083 and EN16258 emission calculation standards.

Reducing emissions

Stolt-Nielsen supports the journey towards low-carbon transportation and storage, and meeting clean air legislation continues to be a priority. For example, in preparation for the upcoming International Maritime Organization (IMO) and EU targets for 2030 and 2050, we are investing in new technologies and processes in all our businesses, including:

  • investigating several novel fuels for our tankers
  • installing more efficient equipment and new technologies across all our operations
  • developing new green technologies, transportation and designs for our tank containers
  • introducing evermore sustainable practices at our sea farms, including recirculating aquaculture system (RAS) technology to conserve energy and water.

Water conservation

Water quality and conservation are crucial for our operations – including tank cleaning, cooling, heating and product line cleaning and farms for our fish – and protecting the marine environment is also key to the sustainability of our business.

Stolt Tankers is installing the most efficient water treatment plants across its fleet, with the goal of covering 100% by 2024. The business has also reduced its local purchasing requirements of bottled water by upgrading onboard water makers and potable water tanks.

Several projects are underway to lower water consumption within Stolthaven Terminals and Stolt Tank Containers, including reducing overall water usage by reusing the condensate from steam heating at terminals and depots.

Stolt Sea Farm invests significantly to improve the water quality around its sites, and we have been permitted to locate several of our farms in conservation areas or natural reserves, demonstrating the rigorous attention we pay to ensuring our business operations are environmentally sound.
