Carbon Audit Part I
4
Introduction to: What is a “Carbon Audit”? Why should we do a “Carbon Audit”? How to do a “Carbon Audit”?
5
What is a Carbon Audit? A means of measuring (accounting or quantification) and recording (reporting) the Greenhouse Gases (GHGs) emissions of an organisation [in tonnes of Carbon Dioxide (CO 2 ) equivalent] Sometimes it is called a ‘Carbon Footprint’
6
Greenhouse Gases (GHGs) Gases that trap heat in the atmosphere Six internationally-recognized greenhouse gases regulated under the Kyoto Protocol: Carbon Dioxide (CO 2 ) Methane (CH 4 ) Nitrous Oxides (N 2 O) Hydrofluorocarbons (HFCs) Perfluorocarbons (PFCs) Sulfur hexafluoride (SF 6 )
7
Why should we do a Carbon Audit? Global Warming is being caused by GHGs Carbon Dioxide (CO 2 ) accounts for 84% of all GHGs
8
Greenhouse Gas Emission Source: Energy Information Administration, Washington D.C. United States
9
Why should we do a Carbon Audit? Kyoto Protocol (latest ratified by UN membership in 2007) establishes targets for industrialised nations to cut GHG emissions Industrialized countries to reduce their combined greenhouse gas emissions by at least 5% compared to 1990 levels by the period 2008-2012
10
Carbon Audit is the first step in developing strategies to manage and reduce GHG emissions of the organization Input for setting GHG target (emission reduction, some may lead to potential saving!) Demonstration of corporate social responsibility Meeting stakeholder expectation / brand value Why should we do a Carbon Audit?
11
How to do a Carbon Audit? 1. Define Organizational Boundary Decide “Where” to measure based on operations that a company legally owned or control Two main options for consolidating GHG emission Management Control Approach Account for all GHG emissions from facilities over which you have operational or financial control Operational control approach most accurately represents the emission sources that an organization can influence Wholly owning an operation, facility, building, process or project Having the full authority to introduce and implement operational policies Licence / contract to operate Equity Share Approach Account for GHG emissions in proportion to the % ownership over the facility
12
Reporting Emission under Management Control Approach & Equity Share Management ControlEquity Share Full ownership100% 30% owned with control of the facility (joint venture company) 100%30% 80% owned without control of the facility (joint venture company) 0%80% 0% owned, but operator of the facility (property management) 100%0% Not owned but have financial or operating lease 100%0% Fixed asset investment0%
13
How to do a Carbon Audit? 2. Define Geographical Boundary Physical location, area, services, facilities, e.g. site boundaries of building 3. Establish base year Set a base year to track emission trends Year in which Scope 1 & 2 data can be reliably collected Single base year Average of several year Rolling base year [the base year is always last year]
14
How to do a Carbon Audit? 4. Define Operational Boundary The specific activities that are components of GHG emission Scope of ControlGHG Sources 1 Direct emission from source owned or controlled by the organization Stationary source Process emission Mobile source Fugitive (leaks or venting) 2 Indirect emission from purchased electricity, gas, heating or cooling Purchased electricity Purchased gas 3 Other indirect emission which are consequences of an organization’s activities, but arise from sources that are owned or controlled by others (optional) Transport-related activities Outsourced activities Waste disposal
15
How to do a Carbon Audit? 5. Identify GHG Sources [Example: Connie Pizza & Noodle Shop] ScopeOperation Process / ActivitiesGHG Sources 1 (Direct)Stationary combustion Emergency generator set Boiler for steam generation Gas cooking stove CO 2, N 2 O Process emission Solid waste treatment (food waste / oil scum / sludge) CO 2, CH 4 Mobile combustion Motorcycle for food deliveryCO 2, N 2 O, CH 4 Fugitive emission Use of refrigerant in air conditioning unit Fire extinguishing equipment HFCs / PFCs 2 (Indirect)Electricity use Lighting / air conditioningElectricity consumption (CO 2 ) Towngas use Towngas for cooking & hot waterConsumption of Towngas (CO 2 ) 3 (other indirect) Paper use Manu, bills, leaflets, printed mattersCO 2
16
How to do a Carbon Audit? 6. Choosing Calculation Methodology Calculation-based approach : Emission = Consumption (activity) x Emission Factor Direct measurement of consumption Consumption mass balance: Total fuel used = (fuel purchased) + {(stock at beginning of year) – (stock at end of year)} Measurement-based approach Predictive emissions monitoring system Continuous emissions monitoring system
17
How to do a Carbon Audit? 7. Choosing Emission Factor (EF) & Global Warming Potential (GWP) Use default emission factors (EPD / IPCC) Fuel TypeEmission Factor (for stationary source)Unit Diesel2.641Kg CO 2 / Liter 0.0239g CH 4 / Liter 0.0074g N 2 O / Liter
18
Global Warming Potential Each GHG has a different ability to trap atmospheric heat, gases with high GWP trap heat better than gases with lower GWP GWP of CO2 is used as standard, other gases can be converted to carbon dioxide equivalent (CO2-e) units
19
How to do a Carbon Audit? 8. Collect Data Collect annual data for each of the activities defined: Amount of Oil / gas combusted, refrigerant leaked, petrol used for vehicles, annual kilowatt hour electricity consumed, etc. Receipts & bills, Purchasing records Measurement data e.g. flow meter, level gauge Maintenance records e.g. replenishment Inventory Monitoring records e.g. discharge concentration
20
How to do a Carbon Audit? 9. Calculate Emission: Diesel used for boiler = 5000L [CO 2 Emission (tons)]: 5000 (L) x Emission Factor (kg CO 2 /L = 2.641) x 0.001(ton/kg) = 13.2 [CH 4 Emission (tons)]: 5000 (L) x Emission Factor (g CH 4 /L = 0.0239) x 0.000001(ton/g) = 0.00012 [N 2 O Emission (tons)] 5000 (L) x Emission Factor (g N 2 O/L= 0.0074) x 0.000001(ton/g) = 0.00004 Converting to CO 2 equivalent: CH 4 Emission (tons) x GWP = CH 4 Emissions (tons CO 2 equivalent) 0.00012 x 21 = 0.0025 N 2 O Emission (tons) x GWP = N 2 O Emission (ton CO 2 equivalent) 0.00004 x 310 = 0.012 Total Emission (tons CO 2 equivalent) = 13.2 + 0.0025 +0.012 = 13.21

Reporting Tota l GHG emissions Our total carbon footprint for 2008 is 175.88 tonnes CO2e Carbon value per employee (per job / project / department) This equates to 11.8 tonnes per full time equivalent staff member Power used per square foot (offices) Benchmark results inter- and intra-industry
23
GHG Target GHG target is a planning tool to drive GHG reduction Examples from corporations: PolaroidReduce CO 2 emissions 20% below its 1994 emissions by year-end 2005; 25% by 2010 ShellManage GHG emissions at 5% or more below 1990 baseline by 2010 IntelReduce PFCs by 10% from 1995 levels by 2010 CLPA reduction in the CO2 intensity from 0.84kg CO 2 /kWh (as at 30 June 2007) to 0.2kg CO 2 /kWh by 2050 Johnson & Johnson Reduce GHGs 7% from 1990 levels by 2010
24
GHG Target Our target for 2009 is to reduce our carbon footprint by 5% as compare 2008 Actions planned include: Understanding how to obtain the greatest energy efficiency from our kitchen and dinning hall ( re- commissioned HVAC systems, window replacement for better insulation, photo voltaic installation) Increasing our efforts to encourage maximum recycling and energy saving by staff Investigating whether it is feasible to compost our food waste.

Carbon Reduction Label 2.
30
Carbon Reduction Label Helps companies communicate their reduction achievement on GHG emission Allows an organization to demonstrate its commitment to manage and reduce GHG emission The rich picture shown below is a simple representatio n of ways that we can reduce our carbon footprint. Draw your own version which shows how you could reduce your carbon footprint. Include drawings for each of the key words. Complete the table first (see next page) as this will help you develop symbols/pict ures for each of the keywords. The attempt the rich picture. Pictures are an essential part of a rich picture. Draw a symbol/pictur e (rough version) to represent each of the keywords listed below. Each symbol/pictur e can be drawn alongside the key words in the table below. When you are happy with each design, transfer it accurately to your rich picture.
