Mitigation Strategies for Scope 2 & 3 GHG Emissions
1. Establishing a GHG inventory
2. Setting an organizational GHG reduction goal
3. Understanding GHG accounting techniques and standards
4. Developing a comprehensive emissions reduction plan
5. Identifying, implementing, and tracking GHG mitigation measures
6. Participating in the carbon offset and renewable energy market
7. Preparing for future climate change regulations
8. Managing and sharing the lessons learned and best practices
Broad Steps for GHG Mitigation
• Purchase/use of zero-emission, renewable electricity
• Purchase of renewable energy certificates (RECs)
• Green power markets (includes RECs and other offset
mechanisms)

RE
Potential Options for RE
Scope 1 (Direct Emissions)
Processes related to production, manufacturing, operation
Through RE based offsets
Offsetting through captive generators based on RE, e.g. biomass, solar, wind Use sources like solar for office/buildings/water heating/cooling; waste management, etc. Use of green offsets/carbon markets
Scope 2 (Indirect Emissions)
Purchase of electricity from grid
Through RECs and RE based offsets
Purchase of RECs Generation of RE based captive power to replace fossil fuel based energy sourced from grid Use of green offsets/carbon markets
Scope 3 (Indirect Emissions)
Transport, waste, etc.
Through RE based offsets
Offsetting through captive generators based on RE, e.g. biomass, solar, wind Use sources like solar for office/buildings/water heating/cooling; waste management, etc. Use of green offsets/carbon markets
