Scope Emissions

Scope 1, 2 and 3 emissions are terms developed by the Greenhouse Gas Protocol. Each category represents the degree that greenhouse gas (GHG) emissions are directly attributable to a person or an organization.

 

To help better understand how Scope 1, 2 and 3 emissions are determined, let’s use an example that is familiar to many of us—mowing a lawn.

 

Here’s how it works:

 

For Scope 1, 2 and 3 emissions, the categorization depends on the amount of control a person or an organization has over the emissions created.  The purpose of the categorization is to bring clarity to the source of and immediate responsibility for the original emission.  Ultimately, the best choice for mowing a lawn would be to use a push reel mower requiring no gas or electricity–just a strong back!
