International maritime expert Mr Andreas Chrysostomou has today discussed improving the energy efficiency of ship design and operation to reduce carbon emissions.

Mr Chrysostomou, Chairman of the International Maritime Organization's Marine Environment Protection Committee highlighted the importance of the decision by the Marine Environment Protection Committee in 2011 to adopt the first mandatory emission reduction measures for the international shipping industry.

Mr Chrysostomou commented that when it came to climate change if we [shipping industry] do not do anything we will not be able to derive what we want from our oceans and seas.

"We have to live in a harmonious co-existence between machinery, man and the sea," Mr Chrysostomou said.

Great Barrier Reef Marine Park Authority Director of Environmental Assessment and Management, Dr Adam Smith, said being aware of the work being done to reduce the environmental effects of shipping will enable more informed decisions to be made about the long-term management of the Marine Park.

"As ports and shipping continue to increase through the Reef, it is important to learn from the world experts how to reduce the industry's environmental impact," Dr Smith said.

The Great Barrier Reef is one of the most diverse and remarkable ecosystems in the world and was recognised as a Particular Sensitive Sea Area by the International Maritime Organization.

"Climate change is the greatest threat to the long-term health of the Great Barrier Reef. It can effect ocean acidification, rising sea temperatures and sea levels and the frequency of severe weather events like cyclones.

"Shipping is a significant international contributor to global emissions and today we are learning that there are steps that can be taken at a local level to improve the energy efficiency of the industry," Dr Smith said.

During his visit to Townsville Mr Chrysostomou will undertake an aerial survey of key shipping and port facilities along the Great Barrier Reef Marine Park. He will also experience the Reef up close during a field trip to Magnetic Island.
