City of Colorado Springs / Environmental Sustainability / Greenhouse GasesCity of Colorado Springs Greenhouse Gas Inventory
In 2007, the City completed its first organizational greenhouse gas inventory begining with a 2007 baseline year with assistance from consultants RW Beck and SAIC. This inventory uses methods consistent with the Local Government Operations Protocol developed in partnership by The Climate Registry, the California Climate Action Registry, ICLEI - Local Governments for Sustainability, and the California Air Resources Board. Here are some of the most recent.
The City emitted about 74,700 metric tons of greenhouse gases in 2011 comprised of 92% CO2, 7% methane and 1% Nitrous Oxide.
As a primarily coal-powered community, 60% of the City's greenhouse gas emissions come from purchased energy (i.e. electricity) with another 16% from mobile sources (i.e. vehicle fuel/air conditioning refrigerants), 10% from stationary combustion (i.e. natural gas and generators), 7% from employee commuting and 7% from solid waste.
The single largest greenhouse gas contributor were the community's streetlights and traffic signals, which were responsible for about 20% of the City's 2011 emissions, even with a portion of streetlights turned off. Other large emitters included the Colorado Springs Airport (16%), Police Department (17%) and Parks and Recreation Division (12%).
An average of 33 metric tons of CO2 was emitted per employee in 2011. An average of 208 metric tons of CO2 was emitted per $1M of expenditure in 2011.

Funding for this effort was provided through ARRA funds by the Department of Energy's Energy Efficiency and Conservation Block Grant. With this tool, the City will be able to measure future year's emissions.
Colorado Springs Utilities data is not shown here as they already undertake their own greenhouse gas inventory each year as a separate effort.
