Introduction<br />

Local governments play a fundamental role in addressing the causes and effects <strong>of</strong> human-caused climate change<br />

through their actions at both the community and government operations levels. While local governments cannot<br />

solve the problems <strong>of</strong> climate change by themselves, their policies can dramatically reduce greenhouse gas<br />

emissions from a range <strong>of</strong> sources and can prepare their communities for the potential impacts <strong>of</strong> climate change.<br />

Within the context <strong>of</strong> government operations, local governments have direct control over their emissions-generating<br />

activities. They can reduce energy consumption in buildings and facilities, reduce fuel consumption by fleet<br />

vehicles and equipment, reduce the amount <strong>of</strong> government-generated solid waste that is sent to a landfill, and<br />

increase the amount <strong>of</strong> energy that is obtained through alternative energy sources. By quantifying the emissions<br />

coming from its operations, this report will enable <strong>Daly</strong> <strong>City</strong> to choose the most effective approach to reducing its<br />

contribution to climate change.<br />

1.1 Climate Change Background<br />

A balance <strong>of</strong> naturally occurring gases dispersed in the Earth’s atmosphere determines its climate by trapping solar<br />

radiation. This phenomenon is known as the greenhouse effect. Overwhelming evidence suggests that modern<br />

human activity is artificially intensifying the greenhouse gas effect, causing global average surface temperatures to<br />

rise. This intensification is caused by activities that release carbon dioxide and other greenhouse gases into the<br />

atmosphere—most notably the burning <strong>of</strong> fossil fuels for transportation, electricity, and heat generation.<br />

Rising temperatures affect local and global climate patterns, and these changes are forecasted to manifest<br />

themselves in a number <strong>of</strong> ways that might impact <strong>Daly</strong> <strong>City</strong>. For example, the San Francisco Bay may experience<br />

rising sea levels and the Sacramento Delta may experience changes in salinity, affecting land uses, water sources,<br />

and agricultural activity. Changing temperatures will also likely result in more frequent and damaging storms<br />

accompanied by flooding and landslides. Reduced snow pack in the Sierra Nevada mountains may lead to water<br />

shortages, and the disruption <strong>of</strong> ecosystems and habitats is likely to occur.<br />
