The goal of the Scope scale is to categorize emissions to help understand where they come from and how to reduce them. Scope 1 are direct emissions, which come from sources owned or controlled by a company and include what’s produced by its facilities and vehicles. Scope 2 are indirect emissions produced by generating the many forms of energy — electricity, steam, heating and cooling — households and businesses use day-to-day.

Scope 3 are the least immediate. They encompass both “upstream” emissions made when a company uses a product or service and “downstream” emissions made when its own products or services are used.
