# Overview

The City of Los Angeles is keenly aware of the negative effects of greenhouse gas pollution and is often in the process of working to counteract the effects of mass individual car ownership by reducing greenhouse gas emissions in other spheres of life. The Port of Los Angeles for example, reduced the amount of a number of toxic emissions during their 2005-2012 green campaign. Additionally, the City has begun to retrofit their public lighting infrastructure with light-emitting diode (LED) bulbs to update the traditional incandescent bulbs, which are shockingly less efficient.
