Pensioners are doing more to protect the UK's environment than any other age group, a survey has found.
Women over 65, named the "green rinse brigade" by researchers, are particularly vigilant about conserving water and recycling.
The survey found 92 per cent of those aged over 65 regularly recycle, four out of five opt for showers over baths and 70 per cent turn off taps while washing.
They also like to use green technology, with 79 per cent choosing energy-saving light bulbs, compared to 66 per cent of the general population. And they are more likely than other age groups to choose a green energy tariff.
However, 25 to 35-year-olds are more likely to re-use carrier bags and buy greenfriendly products.
The study for energy company npower to mark World Environment Day found Britons aged 18 to 24 are more concerned about their career and financial well-being than the future of the planet.
A third of 25 to 35-year-olds claimed they were too busy to help the environment, while 27 per cent of 36 to 50-yearolds said the cost of many fair trade and eco-friendly products were prohibitive.
Adrian White, a social psychologist from the University of Leicester, said: " The younger generation like to think that they are greener than they actually are and, despite often having good intentions, other priorities take precedence".
