The environmental activity at one Putney primary school just never seems to stop.

So it's little wonder that that school was voted the borough's greenest at the recent Wandsworth Green Guardian awards.

Hotham Primary School, Charlwood Road, caught the green bug after an energy audit carried out by the council showed ways it could save energy.

Following the audit, some of those methods were immediately implemented.

Windows were draught-proofed and push taps and a solar powered garden fountain were installed.

And soon after that the school set up an eco group.

Much of the school's environmental work is organised by the group, made up of two children from each class in Years 2 to 6, which meets every week to increase awareness of environmental issues amongst pupils and discuss what the school can do to help.

The group is responsible for conducting the school's environmental review, working out where the school can be more environmentally friendly in a bid to achieve Eco-School status, a European-wide award for schools working to reduce the impact they have on the environment.

The group also helps ensure the school is kept tidy by organising litter monitors and keeping on top of the school's paper recycling scheme.

After taking part in a waste auditing program, the school now checks the levels of waste due for landfill sites itself.

And the school, where very little goes on that doesn't consider the possible environmental impact, also composts its waste and has just taken delivery of a new recycling bank so it can recycle more.

The school has also established a Green Purchasing Checklist to check it is buying as many environmentally-friendly products as possible.

The focus on all things environmental doesn't just take place outside of school hours. The environment is now very much a part of the school's curriculum.

In the last year, year 4 pupils have looked at transport and year 6 pupils incorporated the effects of litter and pollution into their RE work.

Year 1 pupils, meanwhile, have started their own litter campaign warning fellow pupils about the effects of dropping litter around the school using a poster campiagn.

Getting everyone involved is clearly a message the school is keen to spread.

Maggie Gunning, co-ordinator of the schools Eco Group, said: "We want everyone to appreciate how they can look after our environment - at school and generally - and to gain the confidence and knowledge to take responsibility to act, and know they can make a difference."
