California's infrastructure projects have a carbon footprint. Construction materials that build California's roads, mass transit, single family homes and high-density smart growth--all depend on large quantities of construction aggregates (sand and gravel) transported to job sites by heavy-duty trucks. Reducing the distances these trucks travel is a key strategy in reducing greenhouse gases and reducing the state's carbon footprint.

 What You Can Do

A single mile of a single lane of road construction requires 20,000 tons of aggregate. That's 40,000,000 pounds of sand and gravel!

The aggregate is delivered to road construction projects in trucks carrying 25 tons. A single mile of a single lane requires 850 truckloads and twice that number of trips, 1700 trips. CalTrans estimates that these trucks burn .153 gallons of diesel per mile (getting only 6-7 miles per gallon).

What is a TON of Carbon?

A ton of carbon is released each time you:

  • Travel 5,000 miles in an airplane
  • Drive 2,500 miles in a medium-sized car
  • Cut down and burn a tree that was about one foot in diameter and 40 feet tall

CalCIMA stands for California Construction and Industrial Materials Association. We are California’s statewide trade association for aggregate, ready mixed concrete, and industrial mineral producers. In all, there are over 100 producer member companies that include over 500 production sites in California. Our members also include over 60 supplier and service providers to the industry.  Learn more
