Businesses and governments are exploring ways to reduce greenhouse gas emissions for a more sustainable future. In Canada, a program called the Voluntary Challenge and Registry (VCR) asked companies to create plans to cut emissions. Some sectors saw only small emission increases, while others, like fossil fuel production, had significant growth. Estimates suggest the VCR may have reduced national emissions by 5% annually from 1993 to 1998. However, some argue that the VCR had little impact based on different data and case studies.
