Boris Johnson told world leaders at the UN on Thursday that Kermit the Frog was "wrong" when he sang It’s Not Easy Bein’ Green – and it seems Lethbridge Primary School agrees with the PM.

Pupils at the school are leading the way with their environmental efforts and showing it really is "easy to be green".

A council of eco warriors keep standards high around the school by monitoring recycling, energy efficiency, food waste and litter picking.

Two children elected from each class carry out the duties which have already helped the school earn their Eco-Schools Green Flag. 

Eco lead Helen Rowlatt said: “The children are extremely keen to help the environment. 

“Having the green flag status means they’re rewarded and acknowledged. 

“They are really given a sense of achievement when they pass the green flag requirements. 

“The eco warriors are particularly enthusiastic about litter picking. They come back with big bags of rubbish feeling like they’ve made an impact and helped everyone out.

“They enjoy the responsibility of checking that lights and projectors are turned off, and the thermostat is at the correct temperature. 

“They come out of class to meet us and it gives them confidence so they feel good about themselves.” 

Eco-Schools is a charity which awards schools green flag accreditation if they follow a seven-step framework that guides pupils to improve environmental awareness in the school. 

The school encourages the children’s passion for wildlife by filming badgers and foxes with motion sensor cameras. Pupils also build bug hotels from crates and leaves. 

Teachers embed lessons about the environment into the curriculum so pupils can learn about the importance of topics like biodiversity.

Ms Rowlatt added: “The younger children show interest in animals, protecting marine life and ensuring they look after polar bears. 

“Reception classes have a ‘nature detective’ topic about looking after wildlife so they have classes where they make art to do with nature and write about nature. 

“Year 5 and 6 have an Antarctica topic. The older children have a good understanding of the impact of global warming on the earth and learn about weather patterns.” 

The primary school has its own solar panels and joins in with nationwide initiatives such as Walk to School Week and Fairtrade Fortnight.

Eco warriors also get to inform the school’s governors about their environmental achievements every year.
