4.1.3 Summary by Source
When considering how to reduce emissions, it is also helpful to look not only at which sectors are generating
emissions, but also at the specific raw resources and materials (gasoline, diesel, electricity, natural gas, solid waste,
etc.) whose use and generation directly result in the release of greenhouse gases. Such analysis can help target
resource management in a way that will successfully reduce greenhouse gas emissions. Below (Figure 4.3 and Table
4.3) is a summary of San Diego County‘s 2005 greenhouse gas emissions by fuel type or material.
