Past Projects

The Data Working Group addressed:

1. Data access to support DERs by customers and other entities.

2. Opportunities to increase the accuracy of load forecasting.

3. Data-related issues to support DER adoption in environmental and social justice communities.

4. Alignment with other DER-related Commission proceedings.

CalHeatScore, developed by the California Office of Environmental Health Hazard Assessment, uses historical climate, forecasted weather, and health data to score heat events based on their intensity and potential health impacts. Every day, CalHeatScore creates an easy-to-understand scale of 0 to 4 for all ZIP codes in California to communicate heat risks. CalHeatScore connects people to locally relevant resources, like cooling centers, so that they can be prepared when dangerous heat occurs.

Los Angeles County faces flood risks 20 times greater than suggested by federally defined floodplains, and Black, Hispanic, and disadvantaged populations are disproportionately exposed to these risks.

This project will simulate three flood adaptation approaches to capture more stormwater, restore impaired ecosystems, build climate resilience across the region, and advance equity:

1. Raising levees

2. Widening rivers with habitat restoration

3. Green infrastructure and parks

Building on our success with the Extreme Heat Campaign, LARC launched a Clean Energy Education Campaign to create and distribute content in the Los Angeles region to promote more sustainable energy usage. LARC gathered input to ensure relevant materials reach communities who most need access to energy programs. Potential topics include: energy conservation, off-peak consumption, energy efficiency upgrades, utility assistance programs, clean energy jobs, and the health benefits of electrification.

In 2022-2023, RAND's Dr. Kelly Klima led a research team to develop a community-level, stakeholder-informed, and multi-disciplinary analytical framework to identify locations in Southern California where natural gas decommissioning with service replacement via electrification can occur in a just, equitable, and cost-effective way. LARC provided support for project interviews and workshops with varied experts and stakeholders. Learn more about the project in the Project Closeout Meeting Presentation.

LARC crafted a county-wide climate action plan to reduce greenhouse gas emissions and prepare the region to adapt to the impacts of climate change. Known as "A Greater L.A.: Climate Action Framework," this effort is a multi-year process to integrate numerous county-wide and jurisdiction-specific efforts with best practices and model ordinances that ensure a resilient and vibrant future for our communities.

Global climate models are relatively coarse in resolution and provide little information about climate and climate change at scales most relevant to people and ecosystems. Dr. Hall's climate modeling is used to understand the forces shaping climate at the Los Angeles regional scale. Climate studies will include: temperature, snow fall, precipitation, Santa Ana winds, hydrology, sea level rise, and Sierra Nevada snow pack. 

In 2015, LARC participated in utilizing our Framework as a resource to assist the development of the General Plan Guidelines of California’s Office of Planning and Research (currently known as the Office of Land Use and Climate Innovation). The General Plan is essential towards a shared vision for the state, with the Guidelines themselves serving as a resource for regions to draft their own general plans.

LARC’s Framework for Regional Climate Action and Sustainability specifically served as a tool to inform the updates to the Los Angeles regional updates.

In 2018, LARC and the Los Angeles County Internal Services Division Office of Sustainability, released 2010 community GHG inventories for every city in LA County as well as County unincorporated communities. These data serve as a baseline and starting point for critical climate action planning work that must occur throughout the region to comply with the mandates set forth in AB 32 – the Global Warming Solutions Act.

Cities may obtain their 2010 inventory data by contacting their council of governments (COG) or LARC. 

The following report comes from LARC's Convening on Transportation and Land-Use that was held in the Annenberg Beach house in December of 2016. The Convening was held over two-days where local leaders responded to the issues faced in Los Angeles and the solutions that can be brought forth through collaboration within their industries.

In 2013, the County of Los Angeles Public Health Department developed a comprehensive workshop series to transform our workforce into climate change ambassadors. Interested in adapting the workshop series for your own staff?

Each year is a transformative year for the LARC, with the adoption of new governance documents and cultivation of new partnerships throughout the region. The Annual Report provides a summary of the Los Angeles Regional Collaborative for Climate Action and Sustainability’s current efforts – and the efforts of its supporters and partners. Our primary goal is to build local capacity in the Los Angeles Region to take climate action, resulting in a more sustainable and resilient LA.
