Webinar on “Carbon Audit and Greenhouse Gas Emission Verification to ISO/IEC 14064-1-2-3 “

Date, time & venue


Jointly organized by HKIE-EVD, CVD , AMC and Hong Kong Institution of Certified Auditors (HKICA)

Programme Highlight

In Glasgow of this November 2021, the COP-26 Climate Summit is one of the biggest events of our time. The world’s powerful economies are targeted at 2040-60 for the carbon neutralization in order to reduce the potential threats resulted from the extreme climate change. The publication of ISO/IEC 14064-1-2-3 helps the international arena the methodology to be adopted for the “Validation & Verification Body (VVB) for the Greenhouse Gas (GHG) Emission”. This “Standards” set out for operation on the confirmation of the trustworthy and validity of any carbon footprint audits.

The speaker will focus based upon the global perspective on how to conduct a proper legitimate carbon footprint audit for most of the general organization and also mentioning some specific organizations such as steel mills and cement plants of an economy. The objective of which is mainly used for carbon trading in terms of green bonds and/or green finance. A universal system is now being established to implement the accreditation of GHG VVB based on the ISO 14065 and ISO 17029.

A webinar for the above mentioned seminar was conducted on 22 January 2022. This was co-organizing with the Environmental Division, Civil Division, Associate Members Committee and Hong Kong Institution of Certified Auditors. The speaker, Ir CK Cheung presented the different kinds of Greenhouse Gas (GHG) Professionals at the beginning. Five GHS professionals were available, such as GHG Carbon Auditor, Carbon Verifier, Carbon Validator, Carbon Assessor and Carbon Evaluator, they are managing with different industry aspects.

Greenhouse gas (GHS) is the name from carbon, the emission of carbon would cause atmospheric hot temperature with creating climate change.

To combat the greenhouse emission, ISO 14064 was developed to provide a framework for the reduction and removal of GHG emissions. Carbon auditing, carbon trading, carbon offsetting, carbon credits, carbon accounting and footprint were arisen as a result.

ISO14064 was a series of standards related to GHG emissions, validation and verification. ISO 14064-1:2018 was set out for organization level of GHG emissions and removals GHG Quantification and reporting. ISO14064-2:2019 was set out for project level.ISO14064-3:2019 for GHG specified for validation and validation of GHG statement were established.

Carbon audit measures an organization or process GHG emissions including direct emission generated on-site and indirect emission associated with energy use. The total GHG emission will express in unit of carbon dioxide equivalent (CO2e)

In Kyoto protocol, six GHG affecting atmosphere was defined, carbon dioxide, methane, nitrous oxide, hydrofluorocarbon, sulphur hexafluoride and perfluorocarbons (PFCs) Each has its own account of global warning potential (GWP).

In Hong Kong SAR Government and other respective environmental organizations, carbon audit and energy saving are both concerned for measuring GHG emission.

The carbon auditing process has included its objectives, information gathering, site tour, information analysis, reporting and action plan with closing loop. The ISO 5001 energy management developed was assisting in reduction of GHG emission. In conducting GHG audit, defining the boundary of workplace is expected. In fact, the GHG audit is quantifiable, monitoring, measurement and control to reduce the CO2 emission. In addition, the speaker also introduced ISO17029:2019 Conformity assessment –General Principles & Requirement for validation & Verification bodies, and ISO 14065:2000 for General Principle & Requirement for bodies validation and verifying environmental Information.

The seminar ended with question-and-answer session.
