Today the European Union has the most environmentally friendly arsenal of rules in the world and has done more to tackle pressing ecological problems, such as climate change, than any other major power. But it has not always been like this. Caring for the environment did not feature in the Treaty of Rome, the document that gave birth to the modern day EU.

Europe's love affair with the car was moving into top gear, industry was busy belching out pollutants and raw sewage was being pumped into our rivers and seas. This 10-minute report looks at the European Union's contributions over the past 50 years to tackling the major environmental challenges of this continent - ranging from air and water pollution, to dangerous chemicals and waste, to the threat to Europe's biodiversity and the biggest challenge of them all: climate change.
