Scope 1, 2, 3 emissions
Many companies measure and set their emissions reduction goals via a framework of
three "scopes." They are as follows:
Scope 1
This encompasses emissions resulting from the direct activities of your
company, e.g., fuel used by facilities and vehicles that your company owns or
operates.
Scope 2
These are emissions resulting from the generation of procured electricity your
company consumes, e.g., electricity and steam.
Scope 3
This includes the emissions from indirect sources in your company's supply
chain, e.g., purchased raw goods, distribution and transportation, employee
commuting, use of sold products and end of life treatment.

Sequestration
Often discussed in relevance to Greenhouse Gas or Carbon Dioxide sequestration,
sequestration is the act of storing a substance for removal or isolation, i.e. for
sequestration. For carbon sequestration, for example, carbon is store, or
sequestered, in a carbon pool so that it may not affect biological and chemical
processes in the atmosphere. A carbon pool, or "sink," is not a "sink" in the literal
sense, but more of a naturally occurring area in which carbon exists and can be
stored in the environment. A pool or sink might be a geologic formation underground,
a biological formation such as a grassland, or a body of water. Carbon sequestration
is often discussed in tandem with Carbon capture and storage (CCS), however, the
main difference is that CCS involves the transportation of carbon to another location.
