Greenhouse Gases Standards
Greenhouse gases (GHG)
reduction and removal is an increasingly important issue in today’s world. The
American National Standards Institute (ANSI)
accredits GHG Validation/Verification Bodies (V/VB) that, in turn, provide
validation/verification of assertions made by those involved in GHG reduction.
Greenhouse gases are a group
of gases so named for their role in the greenhouse effect, the process through
which those gases reflect light back toward the Earth’s surface, effectively
heating it up. Chief among them are water vapor, carbon dioxide, methane,
nitrous oxide, and ozone, each contributing in different ways to the overall
In response to concerns
raised over the magnitude of the human contribution to the amount of GHG in the
atmosphere and their effects, reduction efforts have been undertaken at every
level of organization, from local projects to regional and multinational agreements
to those stretching over a global scale. Subsequently, assertions put forth by
those involved in GHG reduction, as well as proper enforcement of adherence to
legal and contractual obligations together create a need for a system of
validation and verification by impartial third parties of GHG assertions.
ANSI provides accreditation
for GHG V/VBs through the “ANSI
Accreditation Program for Greenhouse Gas Validation/Verification Bodies”. In
order to earn ANSI accreditation, a V/VB must be operating in accordance to the
requirements defined in the international standard
ISO 14065:2007, including qualities such as consistency and impartiality.
From there, ANSI-accredited entities validate/verify GHG assertions put forth by
those involved in GHG reduction. Lastly, investors, the general public, and
regulators can then act accordingly and with confidence in the validity of the GHG emissions and
reductions data provided to them.
In addition to offering
standards guiding the validation/verification of GHG assertions, ANSI also
offers standards aimed at guiding the quantification, monitoring, and reporting
of GHG emissions, reductions, and removals. A discounted standards package containing five of the standards listed below is also available.
As a further resource, the
web presence of the
ANSI Accreditation Program for Greenhouse Gas Validation/Verification Bodies
itself serves to guide those interested in GHG reduction. From detailing the
accreditation application process to listing
major GHG programs that recognize ANSI accreditation and all currently
ANSI-accredited V/VBs, as well as answering
Frequently Asked Questions, the program’s page is helpful regardless of what
your role in GHG management is.
