Sustainable LA Grand Challenge

This project sought to answer what the overlaps between sustainability and equity are within the context of development projects at L.A. Metro. There is transit-oriented affordable housing being developed along the Metro A Line (formerly Blue) in disadvantaged communities. The purpose of this project specifically was to assess the sustainability and equity concerns of the residents in Watts.

Traffic and vehicle emissions contribute to Los Angeles’ notorious polluted air. The advent of plug-in electric vehicles (EVs) presents a viable solution to this problem by reducing carbon emissions and improving local air quality. However, the widespread adoption of EVs requires the development of reliable and efficient charging infrastructure. Moreover, as EV adoption grows, EV charging will introduce new challenges, such as understanding the interplay between the demands on the electrical grid and EV charging behavior. For example, if many drivers try to charge their vehicles simultaneously, the excessive demand may require utility companies to provide additional power using inefficient power plants, creating unintended consequences for sustainability.  

Los Angeles County is the largest county in the nation with a population of approximately 10 million people. By 2050, the county is projected to have a 15% increase in population, adding 1.5 million more residents. With projected urban population growth alongside the effects of climate change, providing Angelenos with reliable energy, water and an environment that will enhance their health will be a challenge. The UCLA Sustainable LA Grand Challenge (SLA GC) was developed to address these problems and ultimately transition Los Angeles County to 100% renewable energy, 100% locally sourced water, and enhanced ecosystem and human health by 2050. In response to SLA GC’s original goals, The NOW Institute research team undertook a first-round assessment of where the county stands today and what can be done to achieve those targets by 2050.

Vehicle emissions and the resulting air pollution are notable public health concerns in the Los Angeles region. The vast majority of trips in the County are by means other than public transit. One barrier to transit ridership is the distance to a rail or bus system. Factors like sidewalk availability, safety and exposure to heat make traveling to transit stops more difficult, and the effects are more pronounced amongst the elderly and those with disabilities. Ride-hailing services or “Transportation Network Companies (TNC)” like Uber and Lyft can improve access to transit by connecting users to rail or bus stations that are beyond walking distance. Realizing the potential of TNCs, this study proposed combining them with zero-emission vehicles to ultimately reduce emissions, encourage public transit use, and support L.A. County’s ongoing initiatives to reach 100% renewable energy and reduce air pollution.

The Sustainable LA Grand Challenge of UCLA has an ambitious goal of helping transition Los Angeles County to 100% renewable energy by 2050 through innovations in science, technology and policy. An important first step is to determine the balance of accessible renewable energy resources and its distribution and storage. To address this data gap, researchers assessed the 2050 renewable energy potential for the Los Angeles region (defined by the City of Los Angeles, Los Angeles County and the greater metropolitan area, including the surrounding counties) and presented feasible pathways for achieving the 100% renewable energy goal. This study is a preliminary assessment of the energy portfolio for the entire L.A. region.

In 2018, the transportation sector represented over 28%, the largest share, of the total U.S. greenhouse gas (GHG) emissions. Automated vehicles, a rapidly evolving technology, have been modeled to reduce GHG emissions up to 94% and bring accident prevention, smoother traffic and better service to people facing driving difficulties other projected benefits of automated vehicles include reduced infrastructure needs but serving the same demand and potentially more efficient public transportation systems that eliminate transit stops. However, as of 2016 there had not been a field experiment study conducted locally to test and verify the impacts of automated vehicles within Los Angeles County. In this project, researchers ran an automated vehicle prototype on various routes in the county to document the effects on GHG emissions and sustainable transportation.

Physical activity (PA) improves the quality of life and health and is closely linked to the built environment. To promote sustainable and active living in communities, many cities are implementing bike sharing programs. These programs provide co-benefits of reduced emissions by decreasing vehicle miles traveled (VMT). However, no study has been conducted locally to quantify and assess the impacts on PA patterns and health. PASTA-LA, a sister-study of the European Union PASTA project, will be the first and only study outside of Europe to explore the health-related outcomes of bike share in Los Angeles, California. 

The pilot project launched by the City of Los Angeles in May 2015 combines the concepts of carsharing, EVs, environmental responsibility and equity. Operating on at least 80% EVs from the following underserved neighborhoods—Westlake-MacArthur Park, Pico-Union, parts of Downtown, Echo Park and Koreatown—Phase 1 of the pilot project aims to recruit 7,000 low-income residents.   However, carshare services and electric vehicle (EV) advertising tends to focus on middle to upper-middle-class individuals and communities. To address this gap, the objective of Barberena’s project is to provide recommendations on developing a carsharing model that successfully services low-income residents in Los Angeles through qualitative data analyses (e.g. interviews, literature review).  

Transportation emissions are a primary cause of Los Angeles’ notoriously poor air quality. Policymakers and “smart growth” advocates assert that intensifying land use around the public transit rail system will not only help accomplish transportation and environmental goals, but also housing and economic development goals. However, recent studies reveal that rail development is linked to gentrification and displacement of public transit’s core ridership. This project combined literature and policy review, spatial analysis and interviews to investigate underlying causes and develop future policy recommendations that prioritize social equity and minimize displacement.
