Sustainable practices in the built environment are becoming more and more sought after. With LEED gold and platinum becoming the new standard in commercial construction, contractors in all areas of construction are looking for ways to build more sustainably. When creating a strategy for achieving sustainability, transportation has been identified as an area of the construction industry that can help significantly reduce carbon footprint, especially concrete mixer trucks. One question presents itself: Will the cost impact of converting a fleet of concrete mixer trucks from diesel to compressed natural gas outweigh the environmental benefits? This case study will examine the various costs associated with converting CalPortland’s local fleet of mixer trucks from diesel to compressed natural gas. The results of this analysis are comprised in a multi-variable model that includes multiple parameters, government and local policies as well as the cost and availability of compressed natural gas and diesel.
