The Contra Costa County Climate Leaders (4CL) program is a network assisting the county and its 19 cities to inform, support and encourage the measurement and reduction of greenhouse gas emissions. Through education and sharing of best practices we will ensure sustainable, healthy and livable cities.

  • The City’s Construction and Demolition Materials Recycling Ordinance reduces waste and increases recycling of building materials.
  • Concord’s Civic Center, Parks, Fleet Management and Printing Services divisions are all certified as Bay Area Green Businesses. To be certified “green,” participants must be in compliance with all regulations and meet program standards for conserving resources, preventing pollution and minimizing waste.
  • Between 2006 and 2012, Concord residents and businesses decreased waste generation from 6.26 to 3.27 pounds per person per day as solid waste was diverted from the landfill to recycling, composting or reuse.  During this same time period, the rate of diversion away from the landfill to recycling and other alternatives grew from 45% to 71%.

Water Conservation

  • The City provides advice on its website about how residents can conserve water and meet Contra Costa County Water District restrictions.
  • As of June 2014, City of Concord water usage was 37% lower than Contra Costa Water District’s historical baseline – a greater savings than the 15% reduction target set by the District. The savings were achieved through  elimination of water leaks, replacement of inefficient toilets and other fixtures in City buildings, as well as the use of drought tolerant plants in landscaped areas and replacement of irrigation controllers.
  • Meadow Homes Spray Park, designed to filter, treat and recycle the water it uses so to reduce waste, received an Agency Showcase Award from the California Park & Recreation Society, District 3, in the category of Outstanding Facility/Park as well as the American Public Works Association (Northern California) Public Works Project of the Year Award in the “Structures” category.
  • An extensive sewer project in Concord’s greater downtown area will replace the clay pipe lines from the ‘40s and ‘50s to prevent leaks and reduce the probability of water-wasting breaks.


  • The City received five all-electric vehicles in August 2014, will receive another five in February 2015, and has ordered ten electric vehicle charging stations for these City vehicles.  The City reduced its total vehicles from 336 in 2006 to 260 in 2014.
