Calculating & Reporting Greenhouse Gas Emissions

Start with material gases and business types and then expand to the less material ones over time. Takes time to create a robust system…

CLP’s Greenhouse Gas Inventory
Approach References The Greenhouse Gas Protocol (WRI & WBCSD)
decentralised approach operational control
2006 IPCC Guidelines for national Greenhouse Gas Inventories (IPCC)
Scope Started with Scope 1 on generation only Now expanded to include Scope 2 as well for gas
storage, t&d, and retail business Greenhouse gases
Started with just CO2 Now expanded to include CH4, N2O and SF6 Incorporate HFCs and PFCs next year
Independent Verification Statements by facility/plant

Some References for Carbon Disclosure
Government standards requirements (local and/or national)
Voluntary schemes (sector, national, international, etc.)
The Greenhouse Gas Protocol: A Corporate Accounting & Reporting Standard (WRI & WBCSD)
Carbon Disclosure Project (CDP)Extensive survey 1-28 sections @ with 1-15
questions, numeric & text
Global Reporting Initiative (GRI)Recommended indicators EN16 Total direct and indirect
greenhouse gas emissions by weight. (Core)
EN17 Other relevant indirect greenhouse gas emissions by weight. (Core)
EN18 Initiatives to reduce greenhouse gas emissions and reductions achieved. (Additional)
Choice of carbon disclosure should add value to your operations

Why Do We Report?

Reporting
Reporting can drive both performance and stakeholder engagement and thus contribute to managing business-related risks, e.g. regulatory compliance and reputational risks

Made massive errors in reporting CO2
emissions from Castle Peak (and other CLP facilities)
“ So far, out of the 50,000 plants listed only one meaningful discrepancy has been identified: China Light and Power (CLP)… informed us that its massive Castle Peak power plant...emitted significantly less CO2 than the CARMA estimate... CLP presented audited records to support this assertion and the CARMA team quickly made adjustments.”
Why Do We Report?
If you don’t report your emissions, sometimes someone else will guess your emissions…
e.g. CARMA
Unfortunately, retractions are rare and damage already done..

CLP provides environmental performance metrics to a number of international surveys: Carbon Disclosure Project
(CDP) Dow Jones Sustainability Index
(DJSI) FTSE4Good Reputex Trucost Hang Seng Sustainability Index Etc.

None of us can defeat the threat of global warming
on our own – but together we can cool the climate and realise our
