GHG Protocol Initiative

• A Source-level Emission Quantification Tool
• Jointly convened by the WBCSD (World Business
  Council for Sustainable Development) the WRI
  (World Resources Institute)
• Mission to develop promote internationally
  accepted GHG accounting reporting standards
  through an open inclusive multi-stakeholder
  process
• Serves as the premier source of knowledge about
  corporate GHG accounting reporting
  www.ghgprotocol.org

Emissions Quantification Tools

• Building blocks of air quality management
• Key to transition to market-based mechanisms
• Simplifies measurement reporting
• Helps in preparation of plant corporate GHG
  inventory data
• Maintains uniformity in reporting procedures for
  GHG emissions
• Initial project countries
• India cement sector
• Mexico pulp paper sector

Customization India

• Partners
• - USEPA
• -MoEF/CPCB
• - TERI
• - WRI
• Part of the USEPA-MoEF Memorandum of
  Understanding (MOU) USG-GOI climate bilateral

Coverage

• Customization of GHG Protocol for Indian cement
  industry
• Primary focus on GHG, viz. CO2, emissions from a
  cement plant in a financial year
• Secondary focus on criteria pollutants (SO2)
• Road testing at a cement plant in Himachal
  Pradesh

6
Emission sources

• All forms of stationary combustion sources
  kilns, precalcinators, captive power plant (D.G.
  etc), driers etc.
• Process related emissions GHG emissions from
  process operations i.e. emission of CO2 due to
  calcination of raw materials
• Emissions from mobile sources company owned
  vehicles, locos, quarry equipment etc.
• Indirect emissions (import and export of
  electricity)
• For accounting GHG emissions at plant level, all
  emissions are classified as Scope (1/2/3).

Structure of the customized tool

• Consists of simple Excel spreadsheets a
  guidance document to fill the worksheets
• The Excel tool has independent worksheets to
  calculate emissions from various sources
• Some worksheets in the tool
• General plant information
• Custom emission factor for calcination
• Custom emission factor for fuel
• Direct process emissions

9
Structure of the customized tool (contd.)

• Direct emissions from stationary combustion
  (kiln, precalcinator, DG set etc)
• Direct emissions from mobile
• Indirect electricity import
• Indirect clinker imports
• Summary inventory sheet
• Reference sheets (like unit conversion, default
  emission factors etc)

Key data requirement

• Annual clinker production
• Annual fuel consumption data source wise
• Annual electricity purchased
• Average clinker composition (CaO/ MgO content),
  raw material composition, carbon content and CV
  of coal determine EFs
• Average dust emissions from kiln stack
