Seai One Good Idea

Inspire lifestyle changes to save energy and help tackle climate change. This annual SEAI school competition is open to primary and post primary schools.

Each year we ask both primary and post primary school children to come up with One Good Idea to combat climate change. The competition serves to both educate and motivate children to take action.

About One Good Idea 

We all use energy every day at home, in school, and when we travel. Could we use less energy and still meet our needs? Every year we ask primary and post primary students to come up with One Good Idea that will:

  • Save energy
  • Help tackle climate change
  • Inspire lifestyle changes in the people around them

This year we are asking you to make a 1 minute film and launch a creative awareness campaign about it in your community. The film and campaign should show people in your community how your One Good Idea can make a difference to them, their pocket and our planet.

Well done to Meanscoil Gharam, Enniscorthy Co. Wexford who won the SEAI One Good Thing Junior Competition in 2018

About the campaign

The Food Fanatics wanted to get people to take action on climate change! The team set up an awareness campaign aimed at educating primary and secondary school students about food miles, our carbon footprint and climate change. The students got very creative with the production of T-shirts showing off their campaign logo in an effort to raise awareness of their One Good Idea.


A quiz took place which was presented to students along with an informative presentation. Meanscoil Gharman have been very supportive of the team’s goal to educate young people about climate change and have shared their work on Instagram. Posters have been made and circulated around the school and a speaker was invited in order to encourage students to think about purchasing locally made products.
