Oil spills are disasters that can have severe social, economic, and environmental impacts.
They are the release of crude oil or refined petroleum products from tankers, rigs, wells and offshore platforms.
These spills are most common in marine environments, but can also occur on land. They can have disastrous consequences for local ecosystems, and can be expensive due to the loss of oil, and the costs involved in their clean-up.
The number of oil spills, and the quantity of oil that is spilled from tankers has fallen substantially in recent decades.1
