CNSS - Clean North Sea Shipping

Clean North Sea Shipping (CNSS) is an INTERREG IVB project. Partners are harbours, cities, administrations and scientists from 6 North Sea riparian states. CNSS aims at contributing to the reduction of air pollution by ship emissions in the North Sea region. Clean Shipping Technologies, e.g. the use of liquified natural gas (LNG) as ship fuel and cold ironing will be promoted by the project.
Political and strategic processes will be supported by the development of a Clean Shipping Strategy at EU, national and regional level. Basis for this strategic development are among others the following activities:
• Creation of a detailed emission inventory to determine the contribution of ship traffic to air pollution in coastal regions and harbors
• Determination of concentrations of important air pollutants by observations and regional chemistry transport modeling
• Evaluation of different emission reduction scenarios with respect to the air pollutant concentrations by means of numerical modeling
• Analysis of all technological options (state of development, possibilities to be realized, costs) and incentive systems to promote their application
• Development of business concepts for Clean Shipping Technologies
• Supervision and evaluation of concrete show cases
CNSS - Clean North Sea Shipping


More than 90 % of the global freight volume is transported by ships. Increasing prices for ship fuels and the necessity to reduce harmful emissions make alternative propulsion systems for sea going ships economically interesting. In SAIL scenarios for new, competitive hybrid propulsion systems, which combine conventional propulsion with available sailing technologies, are developed.
Conceptual studies for the technical realization of ships with hybrid propulsion systems are combined with an analysis of wind availability to develop scenarios for their future use. Business concepts are worked out for potential investors and users in the maritime partnership. Policy and authorities are assisted by investigating the potential reduction of air pollution due to certain activities and by analysing incentive measures could be supported.
SAIL is an INTERREG IVB North Sea region project that is funded by the European Regional Development Fund (ERDF) from 2012-2015. It includes 17 partners from 7 countries. Project SAIL

GMOS - Global Mercury Observation System

The overall goal of GMOS is to develop a coordinated global observation system for mercury able to provide temporal and spatial distributions of mercury concentrations in ambient air and precipitation over land and over surface waters at different altitudes and latitudes around the world. The observation system is complemented by global and regional models that fill gaps between observation sites in order to provide a complete picture of mercury in the environment. Models help to understand the global transport and fate of mercury and the continuous cycling between different compartments of the Earth system.
GMOS is a FP7 research project (2010 – 2015) with 24 partners from 20 different countries distributed over the entire globe. HZG scientists from the department for environmental chemistry and the chemistry transport modelling group work together in this project.
GMOS - Global Mercury Observation System

MeSMarT (Messungen von Schiffsemissionen in der marinen Tropophäre) investigates ship emissions, their transport and their chemical transformation in the North Sea region. Advanced remote sensing techniques using satellites and MAX-DOAS systems are combined with ship-borne observations of emission plumes from ships. A detailed modelling of the ship emissions and the subsequent application of a chemistry transport model system allows the investigation of the impact of the emissions on the coastal environment and the North Sea.
The project partners in this three-years project are the Bundesamt für Seeschifffahrt und Hydrographie, the Institut für Umweltphysik, Universität Bremen and the chemistry transport modelling group from HZG.

NOSCCA - North Sea Region Climate Change Assessment

NOSCCA is an international initiative launched out of the scientific community to compile a comprehensive interdisciplinary and transdisciplinary assessment of the present scientific knowledge about all aspects of past, ongoing and future climate change in the greater North Sea region. Also changes in relevant environmental and socio-economic systems, due to climate change, will be considered.
