GHG Emissions and Classification
Greenhouse Gases refer to a collection of seven greenhouse gases listed in the Kyoto Protocol, i.e., carbon dioxide (CO2); methane (CH4); nitrous oxide (N2O); hydrofluorocarbons (HFCs); nitrogen trifluoride (NF3); perfluorocarbons (PFCs); and sulfur hexafluoride (SF6). These GHGs are released into the atmosphere as a result of emissions from various activities undertaken as part of several business operations and/or an entity’s value chain.
Classification
GHG Emissions are broadly classified into two sources and three reporting
            categories which are consistently used across these standards and/or frameworks:
                  
                     
                        
                           
                  
                  
               
               Table 6-1 Classification of GHG Emissions
| Source | Reporting Category | 
| Direct Emissions | Scope 1 | 
| Indirect Emissions | Scope 2 | 
| Indirect Emissions | Scope 3 | 
These
            emissions
            reporting categories can be distinguished based on the following definitions:
                  
               - Scope 1 – Emissions from sources that are owned or controlled by an entity
- Scope 2 – Emissions from sources that are purchased and controlled by an entity
- Scope 3 – Emissions from all other sources
These reporting categories are further sub-divided into various activities as listed
                below:
