The Empty Classroom Day was created in 2012 in London by Anna Portch with the support of teachers and educators at London Sustainable Schools Forum to encourage schools to learn outside and to celebrate all the great environmental education happening in London. Then the Project Dirt – the green social network – played a leading role promoting the day.
The idea is simple – schools sign up to say that one class will spend one lesson outdoors on the day, however many schools do a lot more!
