**Carbon Footprint Definition and Calculation**:
– Carbon footprint measures CO2 and methane emissions.
– It considers all relevant sources, sinks, and storage.
– Calculated in CO2 equivalents using global warming potential.
– Reported in tonnes of CO2-equivalent.
– Greenhouse Gas Protocol includes important greenhouse gases.
**Types of Greenhouse Gas Emissions**:
– Greenhouse Gas Protocol divides emissions into Scope 1, 2, and 3.
– Scope 1: Direct emissions from the organization.
– Scope 2: Indirect emissions from purchased energy sources.
– Scope 3: Indirect emissions from upstream or downstream processes.
**Scope 1 and Scope 2 Emissions**:
– Scope 1 emissions come from on-site sources like burning fuel.
– Industry and personal vehicle emissions are Scope 1.
– Scope 2 includes emissions from purchased secondary energy sources.
– Covers emissions not directly produced on-site.
**Comprehensive Carbon Footprint Reporting**:
– Consumption-based accounting includes emissions from imports.
– Territorial-based accounting considers only in-country emissions.
– Comprehensive reporting includes Scope 3 emissions and final demand.
– Helps analyze global supply chains and identify gaps.
**Scope 3 Emissions Assessment**:
– Indirect emissions from organization activities not controlled by the organization.
– Importance of assessing Scope 3 emissions for a comprehensive impact assessment.
– Challenges in managing Scope 3 emissions include complexities in data collection.
– Strategies for reducing Scope 3 emissions involve engaging with suppliers and optimizing operations.
