New Delhi, Dec 1 (IANS): Nordic carrier Finnair Thursday said it has launched the third edition of its "change for good campaign" on international flights for raising funds for implementing "clean water and environment" for children in India.

The programme, which is run in partnership with Unicef, has placed special emphasis on the importance of maintaining sanitation, hygiene and clean water.

The target area in Bihar "is one of the country's poorest and most densely populated areas", the airline said in a statement.

"The idea is that coins and notes of any currency and denomination can be placed for collection in the envelopes provided in aircraft seat pockets, then handed to cabin crew for collection," the airline said.

According to the statement, in the past two years, the project has helped about 224 schools which received new water outlets and toilets.

"Teachers have been trained to teach children to learn about the importance of washing their hands," the airline said.

The airline also added a new element into the campaign, whereby, passengers can contribute by donating their 'Finnair Plus Points' toward UNICEF Finland.

"We also want to offer our customers more ways to contribute to good causes, choosing the ones that are closest to themselves," said Arja Suominen, responsible for corporate communications and corporate responsibility at Finnair.

The in-flight campaign is being carried out on almost all international flights for a period of six week period from Nov 28-Jan8, 2012.
