Environmental research –

activities within Eco Ship

• What is Ecoship and sustainability?  

• Challenges for Ecoship

• Research groups and projects

• Maritime environment reserach in the world 

• Future research areas in Ecoship?

Complex systems

Many criteria

Need for systems approach for decision making

But alsoknowledge of the parts

”Sustainability means meeting the needs of today without reducingthe quality of life for future generations”

sustainability?

According to Agenda 21 – Resource use and environmental impact

But also– Social and economic dimensions– The role of major groups
