goods, procuring products with recycled content, implementing composting, offering user training, and conducting zero waste audits offer practical ways to improve performance and reduce emissions associated with waste ( MRc2: Waste Reduction Strategies ).

Ecological conservation and restoration Waste reduction strategies also mitigate harm to ecosystems by diverting waste from landfills and incineration, which release pollutants into soil, water, and air. Contaminated rainwater can seep harmful chemicals into groundwater, affecting local habitats. Landfills emit methane and carbon dioxide among other harmful pollutants, which deteriorate air quality and contribute to climate change. By reducing waste sent to these systems, projects lessen their environmental burden.

Ultimately, the MR category empowers project teams to rethink the use and procurement of materials, track and reduce waste generation, reduce emissions, and protect ecosystems. These efforts advance sustainability goals and contribute to a healthier, more resilient built environment.
