We aim to apply best-practice standards of corporate responsibility. In order for us to see how we're performing in comparison to similar companies, we take part in a range of benchmarking exercises.

We have been highly ranked in a number of corporate responsibility league tables. The list below shows the main benchmarks we monitor along with our recent performance.

• Business in the Community's Corporate Responsibility Index: a voluntary benchmark of responsible business practice by UK companies. We remain in the top 'platinum' band. 
• Business in the Community's Business Environment Index and a benchmark of practice on environmental issues by UK companies. BAA continues in the 'premier league' of companies scoring more than 99% and we are included in the platinum band.
• Dow Jones Sustainability Index: a global index tracking the financial performance of leading sustainability-driven companies worlwide. BAA took part in the index until the company was bought by Ferrovial in 2006. Ferrovial has been included in the Index for five years and is the leader in the heavy construction industry.
• BAA is also a member of the London Benchmarking Group. This is a group of over 100 companies that manage, measure and report on their community involvement.
