Describes the applicable types of greenhouse gases (GHG) emitted as a result of the organization's operations during the reporting period.
Choose all that apply:
Organizations should footnote all assumptions used, including source of data.
This metric is intended to capture the different types of greenhouse gas emissions reported.
The Greenhouse Gas (GHG) Protocol, the most widely used international accounting tool to understand, quantify, and manage greenhouse gas emissions, categorizes direct and indirect emissions into three broad scopes.
Scope 1/Direct GHG emissions are emissions from sources that are owned or controlled by the reporting entity.
Scope 2/Indirect GHG emissions are emissions that result from the activities of the reporting entity but that occur at sources owned or controlled by another entity.
Scope 3 GHG emissions are emitted directly and indirectly by actors across the organization's value chain.
For more information on the GHG Protocol, organizations should refer to the following:
GHG emissions resulting from land use, changes in land use, bioenergy, and related topics can be reported in conjunction with indirect emissions across the organization's value chain.
Organizations can use this metric in conjunction with Greenhouse Gas Emissions: Total (OI1479) to detail the GHG emissions for a specific scope. For GHG related to products, organizations may report Greenhouse Gas Emissions of Product (PD9427) and Greenhouse Gas Emissions of Product Replaced (PD2243).
Metrics identified as "cross-category" are those that are relevant to any IRIS+ Impact Category or Impact Theme (i.e., these metrics are not specific to any particular industry/category or theme).
June 2022 - IRIS v5.3 Released (current version)
Immaterial change. Minor revisions to definition and usage guidance for clarity.
May 2021 - IRIS v5.2 Released
Material change. Greenhouse Gas Emissions (OI5732) replaced Greenhouse Gas Types Scopes (OI5732). Metric name, definition language and usage guidance modified to increase clarity.
January 2020 - IRIS v5.1 Released
New metric. Greenhouse Gas Emissions Types (OI5732) was developed via the IRIS+ Sustainable Forestry Expert Subgroup.
IRIS Metrics Work Better in Sets
To use IRIS metrics—and the resulting data—to understand impact performance, IRIS metrics should be used and analyzed in generally accepted sets and according to well-defined objectives. IRIS+ gives you access to generally accepted Core Metrics Sets aligned to common Impact Themes and Sustainable Development Goals (SDGs).
