Greytown School has achieved the highest level in Enviroschool rankings, receiving a Green-Gold award for promoting sustainability in the school and community since 2004.
Last week, the school was presented with a certificate and flag by Greater Wellington Regional councillor Gary McPhee and South Wairarapa Mayor Adrienne Staples.
It is the second school in Wairarapa to achieve Green-Gold, after the success of Douglas Park School in Masterton.
Through their students, enviroschools make a commitment to sustainability, working through stages from bronze, silver and green-gold.
Greytown School's programmes included the "North Creek Project", restoring a concrete drain to a natural stream environment, and a school production narrating the annual longfin eel migration.
