Brentwood Reports GHG Emissions


Brentwood, a suburb of St. Louis, has completed and published a municipal greenhouse gas inventory. The inventory studied community emissions and emissions from government operations for the baseline year of 2010. The latter are a subset of the former, but municipalities break them out separately because they have direct control over their own emissions, while they can only influence community emissions indirectly. Many municipalities also want to demonstrate leadership on the issue.

Brentwood Comm GHG Chart 2010Total Brentwood community emissions were 224,878 metric tons of carbon dioxide equivalent (MTCO2e). According to the report, Brentwood had a residential population of 8,025 in 2010, yielding per capita emissions of 28.02 MTCO2e/person.

The first chart at right shows community emissions by sector. The commercial sector was largest, accounting for over 40% of total emissions. The residential sector and transportation sectors were second and third largest. The streetlight sector represents a few privately lighted streets. The second chart at right shows community emissions by source. Almost 3/4 of Brentwood’s emissions derived from the consumption of electricity. Transportation fuels, gasoline and diesel, together accounted for 16.65% of emissions. Natural gas consumption accounted for only 10.4% of emissions.

Brentwood Govt GHG Chart 2010Total government GHG emissions were 3,291 MTCO2e, about 2% of community emissions. The second chart at right shows government emissions by sector. The largest portion of emissions was accounted for by energy consumption in the city’s buildings and facilities (65%), which were nearly twice as much as all other sources combined. The vehicle fleet accounted for 13% of emissions, while employee commute accounted for 12%.

Brentwood operates a recreation center with an ice rink. This facility alone consumed 2.2 million kWh of electricity, more than 2/3 of the electricity consumed by all Brentwood government buildings.
