SDG&E has been an early leader in greenhouse gas (GHG) emissions reporting. We joined the California Climate Action Registry (CCAR) in 2003 and The Climate Registry (TCR) in 2008. We supported the development of GHG reporting industry protocols early on and began voluntary reporting of our 2004 GHG emissions inventory to CCAR in 2005, prior to mandatory reporting under AB 32 in 2009 for 2008 emissions. We also began third-party verification of our first CCAR 2004 emissions inventory in 2005. SDG&E's GHG metrics are shown below:
| DIRECT GHG EMISSIONS | 2010 (metric tons of CO2e) | 2011* (metric tons of CO2e) |
|---|---|---|
| Stationary Combustion - Scope 1 | 1,402,748 | 923,781 |
| Mobile Combustion - Scope 1 | 18,448 | 19,545 |
| Process - Scope 1 | 13,029 | 15,487 |
| Fugitive - Scope 1 | 306,384 | 307,836 |
| TOTAL DIRECT EMISSIONS | 1,740,610 | 1,266,649 |
| INDIRECT GHG EMISSIONS | 2010 (metric tons of CO2e) | 2011* (metric tons of CO2e) |
| Purchased Electricity - Scope 2 | 326,089 | 299,785 |
| TOTAL INDIRECT EMISSIONS | 326,089 | 299,785 |
* 2011 emissions data is unverified and subject to change.
Voluntary GHG emissions reports are available on the website of TCR. To see SDG&E's GHG emissions reports, go to the entity emissions summary reports.
