Reducing CO2 Emissions from Construction in LA County
Abstract
Climate change, driven by greenhouse gas (GHG) emissions such as carbon dioxide (CO2) and nitrogen oxide (NOx), is one of the most pressing issues experienced worldwide. Extreme weather events, worsened air quality, rising sea levels, and the impact on food have worsened yearly due to the increasing CO2 emissions released annually. In particular, Los Angeles County significantly contributes to increased GHG emissions, with a historically high carbon footprint, releasing approximately 80 million metric tons of CO2 yearly (De la Rue Du Can, 2008). The majority of these emissions are caused by construction equipment and the diesel required for operating machines. Although construction plays a crucial role in global development by building infrastructure and housing, it is a major contributor to greenhouse gas emissions, with construction vehicles being significant polluters (Sizirici B, 2021). As a response, the U.S. Green Building Council of Los Angeles (USGBC-LA) is taking the initiative to explore an electric track for the future of construction. By electrifying construction equipment, the construction industry can significantly lower its environmental impact and comply with evolving regulatory standards, while promoting public health. This project investigates the feasibility of transitioning to electric construction equipment, specifically examining the cost of ten mini excavators to reduce environmental impact. We also explore the limitations that may hinder the adoption of these clean technologies, including technological challenges, costs, and workforce implications. Additionally, we describe financing options through programs such as the Clean Off-Road Equipment Voucher Incentive Project (CORE) and the Carl Moyer Memorial Air Quality Standards Attainment Program (Carl Moyer Program) and analyze cost reductions over five years. Our study shows that the long-term benefits of our project outweigh the costs, supporting Los Angeles’s sustainable goals. This construction equipment option is economically viable and offers zero emissions, aligning with LA’s vision for a sustainable society.
