Reduce greenhouse gases equivalent to 660 million miles driven per year to cut our carbon footprint.
The Earth’s atmosphere naturally contains greenhouse gases, such as carbon dioxide, water vapor, and methane, which are reaching unnaturally high levels due to human activity. LA County is a major source of Greenhouse Gas emissions and a phenomenon known as the heat island effect, whereby a metropolitan area is significantly warmer than its surrounding rural areas.
The LA River offers an opportunity to reduce the carbon footprint of our community. We are currently evaluating various strategies for their potential impact to reduce Greenhouse Gases. To date, we believe our concepts have the potential to reduce emissions by 76,000 metric tons of carbon equivalent per year—or, 660 million car miles.
Methodology to impact our energy usage:
- Reducing Loads – the most efficient way to reduce carbon footprint is to reduce the need to heat, cool, etc. our environments. This can be supported by urban forestry which will help to reduce urban heat island.
- System Optimization – the next most efficient way to reduce carbon is to reduce the energy required to operate systems in our environment. By reducing our water imports and depending on our local water supply, we can dramatically reduce emissions created during delivery of water to the Southland.
- Renewable Energy Substitution – using energy from renewable sources, such as solar, wind and hydropower, in lieu of fossil fuel based sources will reduce carbon footprint, but not as efficiently as the first two methods. These renewable energy opportunities can all be incorporated along the river, but are best evaluated on a project by project basis.

But what does a ton of carbon really mean?
The EPA offers the following equivalency.
One hundred metric tons of carbon equivalent is approximately:
- 77 cars driven for a year
- 870,000 miles driven by car
- 131 tons of waste sent to a landfill
- 33.5 homes energy use for a year.
