A high school senior in Hawaii is running a week-long sustainability push built around small everyday actions, a positive story for local environmental groups and students.

• Aloha Green Week turns sustainability into simple daily steps instead of big projects.
• The effort follows the United Nations Sustainable Development Goals as a framework.
• It grew out of earlier work: an educational video game about protecting Hawaii's monk seals, and thank-you letters to pandemic frontline workers.
• People can download a pledge on Instagram, post what they plan to do, and tag three others to join.

Outlook: The campaign will keep spreading through social media pledges, with more sustainability fairs expected to follow.
