Which companies use the GHG Protocol?

Could you please elaborate on the companies that currently utilize the GHG Protocol in their operations? I'm particularly interested in understanding the industries and sectors that have adopted this framework, as well as any notable examples of how these companies are leveraging it to reduce their greenhouse gas emissions and contribute to sustainable development goals. Additionally, I'm curious about any challenges or successes these companies have encountered while implementing the GHG Protocol, and whether there are any trends or patterns emerging in terms of the types of businesses that are embracing this approach.
