UNESCO initiative

In a statement released Thursday, UNESCO reported that over 80,000 schools across 87 countries are following the recommendations in the Green school quality standard released in May 2024.

The initiative promotes green learning environments through governance, facilities and operations, teaching, and community engagement. This includes setting up “green governance committees” and training teachers in sustainable management practices.

Peacekeeping and the environment

In a video released Wednesday, UN Under-Secretary-General for Operational Support Atul Khare and Environment Section Chief Joanna Harvey outlined how UN Peacekeeping is reducing its environmental footprint.

Efforts over the past decade include bringing renewable energy to missions, requiring newer, more efficient generators, supporting local energy providers, and investing in sustainable infrastructure.

“We want to leave behind a legacy… [of] projects that are created by us which are finally beneficial to the local communities,” said Mr. Khare. – UN News
