Event Organizers Sector Supplement - Global Reporting Initiative

EN25 Identity, size, protected status, and
biodiversity value of water bodies and
related habitats significantly affected by
the reporting organization’s discharges
of water and runoff.
1. Relevance
This Indicator is a qualitative counterpart to quantitative
Indicators of water discharge that helps to describe
the impact of these discharges. Discharges and runoff
affecting aquatic habitats can have a significant impact
on the availability of water resources. Identifying water
bodies affected by discharges provides an opportunity
to identify activities in regions of significant concern,
or areas where the reporting organization may face
specific risks due to community concerns, limited water
resources, etc.
2. Compilation
2.1 Identify water bodies significantly affected by the
reporting organization’s water discharges that
meet one of more of the following criteria:
• Discharges account for an average of 5% or
more of the annual average volume of the
water body;
2.2 Report water bodies significantly affected by water
discharges based on the criteria above, adding
information on:
• Size of water body in cubic meters (m 3 );
• Whether the source is designated as
a protected area (nationally and/or
internationally); and
• Biodiversity value (e.g., number of protected
species).
3. Definitions
None.
4. Documentation
Information on the status of a water source or protected
area can be obtained from local or national waterrelated
ministries or government departments, or
through research initiated by the organization or other
institutions, such as environmental impact studies.
5. References
• IUCN Red List of Threatened Species.
• Ramsar Convention on Wetlands.
• Discharges that, on the advice of appropriate
professionals (e.g., municipal authorities), are
known to have or are highly likely to have
significant impacts on the water body and
associated habitats;
• Discharges to water bodies that are recognized
by professionals to be particularly sensitive
due to their relative size, function, or status as
a rare, threatened, or endangered system (or
support a particular endangered species of
plant or animal); or
• Any discharge to a Ramsar-listed wetland
or any other nationally or internationally
proclaimed conservation area regardless of the
rate of discharge.
