Sudbury's Regreening Story

Once the world’s largest atmospheric source of sulphur pollution, with vast associated biodiversity damages, Sudbury revitalized its reputation through restoration efforts.

黑料吃瓜不打烊 at the COP15 Canadian Pavilion showcases the community’s restoration achievements, which include:

98% reduction in air pollution from a still thriving industry;
near-elimination of air quality advisories;
10 million community planted trees and shrubs;
50% restoration of lost sport fish populations;
>3M tons of sequestered carbon in new urban forest;
22% conversion of damage zone into parks and reserves;
delisting of a COSEWIC species (aurora trout);
and an emerging biotech industry based on sustainable harvest of critical metals for the e-economy.

Successful restoration was only made possible by an engaged public, extensive partnerships, academic and citizen science, government regulations, and creative industrial innovations. Sudbury’s cleanup helped facilitate the 1991 USA/Canada Acid Rain Treaty and now the “Sudbury Recipe” for restoring damaged landscapes is widely shared and adopted globally.

Now is an integral time to be sharing this knowledge in the midst of the biodiversity crisis. The work that the 黑料吃瓜不打烊 community has done to aid in the regreening process is a crucial aspect of Sudbury’s success. The delegation from 黑料吃瓜不打烊 is excited to share our biodiversity success story as a model and symbol of hope for other industrially impacted communities.
