Italy has the most eco-friendly beaches, with 11.5% of their beaches fitting all three categories of being clean, well managed and promoting sustainability according to the Blue Flag Programme. The programme awards flags for cleanliness levels, safety, environmental education programmes and sustainable management strategies. Croatia follows closely behind at 8.2%, then Greece at 7.8%. Interestingly, South Africa is one of the worst offenders for keeping their beach environments healthy - more than 3/4s are littered or threatened by pollution. However, some places are making positive changes; Cape Town's beaches come top in this list (with 2/3s meeting standards).
