First Address to Irish Parliament From a British PM
(Edited)

But increasingly we share a common agenda and common objectives: completion of the Single Market and structural economic reform; better conditions for growth and jobs in Europe; successful enlargement; a united and coherent foreign policy voice for Europe; a more effective fight against crime, drugs, illegal immigration and environmental damage; flexible, open and accountable European institutions.

environmental = related to the natural world (life, air, water, land...)
This means defining the priorities where common European action makes obvious sense and can make a real difference, like economic co-ordination, foreign and security policy, the environment, crime and drugs.
