Indicator: CO-67 Progress of the Australian shipping fleet towards meeting the targets of the International Convention on the control of harmful anti-fouling systems on ships
Data
The International Convention on the Control of Harmful Anti-fouling Systems on Ships states that, by 1 January 2008 (effective date), ships either:
- shall not bear such compounds on their hulls or external parts or surfaces; or
- shall bear a coating that forms a barrier to such compounds leaching from the underlying non-compliant anti-fouling systems.
A range of projects have been put in place to facilitate achievement of the Convention targets, including studies of the effects of anti-fouling biocides and evaluations of some alternatives.
However, no data on progress towards these targets, such as proportion of the Australian shipping fleet currently complying, appear to be available at this time.

Issues for which this is an indicator and why
Coasts and Oceans — Direct pressure of human activities on coasts and oceans - Direct pressure of shipping
Antifoulants are used on ships’ hulls to control marine fouling and rely predominantly on combinations of copper and tributyltin (TBT). Deposition of antifoulants at ship grounding sites and at mooring sites and slipways represents a significant risk to marine life. Leaching from antifouling paints, TBT and copper are directly available in the water column. TBT affects cell metabolism in organisms by causing malformations of the cell membranes, which adversely affect biological functions.
No indicator of the impact of anti-fouling paints across Australian ecosystems have been identified. However, proportion of shipping using such paints may be broadly indicative of the extent of the pressure.
Other indicators for this issue:
- CO-27 Number, frequency, extent and volume of oil spills from all sources
- CO-32 Number of injuries to marine animals from marine debris
- CO-50 Number of collisions with marine animals
- CO-51 Quantity of sewerage and ballast water dumped by shipping
- CO-52 Evidence or examples of impacts of channel dredging for shipping on marine life
- CO-53 Evidence or examples of noise or visual disturbance of marine species by human activities
- CO-65 Correlation between various human activities and introduction of coastal and marine species
- LD-40 Current research into pressures and contributions of naturalised introduced species
Biodiversity — Pressures on biodiversity - Pressures on marine biodiversity: pressures of shipping
Toxic paints from shipping is a pressure on marine biodiversity. No indicator of the impact of anti-fouling paints across Australian ecosystems have been identified. However, proportion of shipping using such paints may be broadly indicative of the extent of the pressure.
