My sister site. A website of video tutorials for integrating the UN global goals and digital literacies into language teaching.

A fantastic resource with social and environment justice lesson plans and self-study materials based around the magazine on the topic New Internationalist.
This is a great new collaborative project for sharing environment-themed ELT materials and getting teachers who care about the environment together.
