The City of Palo Alto is a proud sustainability leader. Learn more about current and past efforts to reduce carbon emissions and preserve our landscape and natural resources.

2022

Palo Alto earned a spot on environmental impact non-profit, CDP's 2022 Cities A List. Palo Alto is recognized as one of 122 cities on the list taking bold leadership on environmental impact and transparency. Of the over 1,000 local governments scored by CDP in 2022, only 12% received an A. A List Cities must disclose publicly through CDP-ICLEI Track and have a community-wide emissions inventory, among other actions.
The Advanced heat Pump Water Heater (HPWH) Pilot Program was launched after receiving Council Approval in September. The program will make it easier and more affordable for residents to switch to a HPWH, with a goal of replacing 1,000 gas water heaters by the end of 2023. If fully subscribed, the program will reduce emissions by about 800 MT CO2e per year. Site visits for the program are projected to begin in early 2023.
City Council passed the 2022 updates to the Green building Ordinance and Energy Reach Codes (referred to as "Reach Codes"). These carry over the requirements of the 2019 Reach Codes, with additional requirements in the areas of building electrification, EV infrastructure, water efficiency, and embodied carbon in building materials. The Reach Codes will go into effect in January 2023, and collectively will avoid over 3,420 MT CO2e per year.
In September, City Council accepted the S/CAP Goals and Key Actions(PDF, 760KB). This document incorporates extensive community feedback and guidance from the S/CAP Ad Hoc Committee, and is meant to be a high-level road map to achieving Palo Alto's 80 x 30 goal. Council acceptance of the S/CAP Goals and Key Actions allowed staff to commence California Environmental Quality Act (CEQA) evaluation of the full S/CAP.
In July, the City initiated a "One Water" planning effort. The One Water Plan will serve as a long-term guide to better prepare for future uncertainties like multi-year drought, climate change, and more.
The Sea Level Rise Vulnerability Assessment was completed which will inform the development of a Sea Level Rise Adaptation Plan.
In June, City Council adopted an updated Tree Ordinance that expands tree protection to include additional protected tree species, roughly tripling the number of trees that would be classified as "protected" and imposes new requirements for developers seeking to remove these trees. The updated Tree Ordinance went into effect on July 21, 2022.
Palo Alto received an Honorable Mention in the “Small City Category” of the 2022 Climate Protection Awards from the U.S. Conference of Mayors. The award winners are the 16th class of mayors to be honored for successful local climate action, changing how energy is used and produced in cities resulting in reduced carbon use and emissions. Palo Alto’s mayor received the award at the U.S. Conference of Mayor’s 90th Annual meeting in Reno, Nevada on June 3 and spoke on the panel, EVs and Cities: Early Lessons from Public and Private Sector Deployments. The Mayor and Palo Alto City staff were recognized for the Multifamily Gas Furnace to Heat Pump Retrofit Pilot(PDF, 4MB).
City of Palo Alto Utilities completed the Multifamily Gas Furnace to Heat Pump Retrofit Pilot(PDF, 4MB), which aimed to identify viable retrofit options and validate the cost and benefits of retrofitting existing gas furnace systems with energy efficient electric heat pump alternatives at an affordable 24-unit multifamily apartment complex. The pilot provided direct benefits to residents through improved indoor air quality and bill savings, as well as increased comfort and safety. At the community level, the pilot will reduce the City’s greenhouse gas emissions and serves as a case study for future electrification projects in multifamily buildings.
Palo Alto was accredited by the National Arbor Day Foundation as a Tree City USA for the 35th year, and as a Tree Line USA electric utility for the 7th consecutive year. The Tree City USA program recognizes cities that help care for and increase our urban tree canopy. Our urban forest provides numerous benefits to our community including cooler temperatures, cleaner air, higher property values, and healthier residents.
In partnership with the local organization, Grassroots Ecology, the City continued to update the 12 bioretention areas along Castilleja Avenue, Sequoia Avenue, and Miramonte Avenue as part of the Southgate Beautification and Re-Greening Project. The Green Streets Stewards Program was initiated to help community members maintain and care for the sites to ensure long-term success.

2021

Launched an update to the Sustainability and Climate Action Plan (S/CAP) to develop the strategies needed to meet our sustainability goals, including our goal of reducing greenhouse gas (GHG) emissions 80 percent below 1990 levels by 2030 (the “80 x 30” goal).
Formed an S/CAP Ad Hoc Committee to guide the development, implementation, and communication of the S/CAP and to engage with a stakeholder group of domain experts and community activists.
Completed an Impact Analysis(PDF, 377KB) of the goals and key actions needed to achieve 80 x 30, including the development of Buildings, Vehicle Emissions, Mobility, EV, and Finance Models and accompanying technical memos.
Palo Alto received the League of American Bicyclists’ Gold-Level Bicycle Friendly Community (BFC) Award in recognition of the years of work our transportation professionals, bike advocates, and residents have put in to creating transportation and recreational resources that benefit residents of all ages and abilities while encouraging healthier and more sustainable transportation choices. Palo Alto is one of 34 Gold Level BFCs out of a total of 487 BFCs nationwide.
The Office of Transportation launched the South Palo Alto Bikeways Project - the biggest protected bike lane project in town so far. The South Palo Alto Bikeways project proposes bicycle facility improvements for the Waverley Multi-Use Path on Palo Alto Unified School District (PAUSD) land, Fabian Way, and East Meadow Drive. This project invests in the city’s bicycle network to provide safer infrastructure for students commuting to school via bicycle and encourages mode shift to reduce greenhouse gas (GHG) emissions. The project was awarded federal funds for construction and will initiate the construction phase in 2023.
In March 2021, City of Palo Alto Utilities launched a new Business Advantage Program to help small and medium business customers save energy, money, and improve indoor air quality. The program provides businesses with a free Energy Management System, a cloud-based energy management portal, and free MERV-13 air filters to improve indoor air quality. As of December 2021, over 50 systems have been installed.
In May, Council approved the updated 10-year electric efficiency goals between 2022 and 2031(PDF, 446KB). The estimated energy savings in 2031 based on these goals is around 4.4% of the City’s total electric load.
Utilities completed a report on the Impact of Decarbonization on the Resiliency of Single Family Homes in Palo Alto(PDF, 2MB). The report found that while electrical systems are susceptible to short, local power outages caused by typical annual weather events, the restoration time for electrical services is significantly faster than natural gas services in major outage scenarios such as earthquakes.
In November of 2021, City of Palo Alto Utilities (CPAU) was recognized with a leadership award from the U.S. Environmental Protection Agency (EPA) for its refrigerator recycling program. CPAU was among 14 partners who were recognized for reducing ozone-depleting substances and greenhouse gas (GHG) emissions through insulation foam recovery, significant growth of an appliance recycling program, and demonstrating a notable commitment to advancing the goals of the Responsible Appliance Disposal (RAD) program. Since becoming a RAD Partner in 2009, Palo Alto Utilities has processed a total of 1,232 units, reducing GHG emissions equivalent to those from 1,330 homes' energy use for one year.
Palo Alto has partnered with MidPen Housing in a pilot to replace the gas furnaces at Page Mill Court, a low-income multifamily apartment complex, with efficient heat pump systems. The pilot was funded by a grant from the Bay Area Air Quality Management District (BAAQMD). The retrofit work was completed for all 24 apartment units in December.
City of Palo Alto Utilities was recently announced a designee of the American Public Power Association Smart Energy Provider (SEP) Award for the third year in a row. The SEP designation recognizes public power utilities for demonstrating leading practices in four key disciplines: smart energy program structure; energy efficiency and distributed energy programs; environmental and sustainability initiatives; and the customer experience.
Completed the Sea Level Rise Vulnerability Assessment
Public Works Watershed Protection developed Sea Level Rise Curricula for ages K-5 in partnership with Grassroots Ecology
Collaborated with Santa Clara County and other jurisdictions to evaluate the State’s new SB1383, Short-Lived Climate Pollutants requirements and drafted a new ordinance on an Edible Food Recovery Program for food service establishments, the process of how the food donations will occur and a county wide outreach for the food services establishments and food recovery organization; developed a work plan and checklist to ensure the city is in compliance with the many regulation requirements and exploring how the new procurement requirements of recovered organic waste products will be met.
Collaborated on a “Serve-It-Safe” reuse pilot with Upstream, Dishcraft and Tootsie’s for the use of reusable dine-in and take-out reusable food containers. Pilot active at Tootsie’s café at the Stanford Barn
Received a $1.2 million Environmental Protection Agency grant to green Parking Lot A in downtown Palo Alto by retrofitting with green stormwater infrastructure (GSI) elements. The Project will capture 80% of the runoff from the treatment area, provide 282,000 gallons per year of stormwater retention on average, reduce PCBs and mercury pollution entering the Bay and capture 1.9-2.8 million particles/year of microplastics which would otherwise enter creeks or the Bay.
Palo Alto was selected as a Tree City USA by the Arbor Day Foundation for the 34th year! The Tree City USA program recognizes cities that help care for and increase our urban tree canopy. Our urban forest provides numerous benefits to our community including cooler temperatures, cleaner air, higher property values, and healthier residents.
Completed a new, year-round bicycle and pedestrian overcrossing over Highway 101 at Adobe Creek near the City’s southern border. The new Highway 101 Pedestrian/Bike Bridge connects the community all year round to amenities like the Baylands Golf Links, hiking and biking the Baylands Nature Preserve, experiencing Byxbee Park, connecting to the San Francisco Bay Trail, and so much more.
The Office of Emergency Services was awarded a $200,000 State Homeland Security Grant, which was used to purchase a custom-built Solar Generator Trailer (SGT). The SGT is an important resource for the City to provide electric power to the Mobile Emergency Operations Center (MEOC) and other critical systems that require electricity to operate.

2020

Palo Alto reduced greenhouse gas (GHG) emissions an estimated 50.6 percent from 1990 levels, despite a population increase of 21.8 percent during that same time period. This equates to 5.7 metric tons of carbon dioxide equivalent (MT CO2e) per Palo Alto resident in 2020 compared to 14 MT CO2e per Palo Alto resident in 1990. The California Air Resources Board 2017 Scoping Plan Update recommends local government goals of 6 MT C02e per capita by 2030. It is important to note, however, that 2020 was the start of the COVID-19 pandemic, and the 2020 GHG inventory includes pandemic-related impacts, such as shelter-in place orders and changes in how and where people worked, resulting in emissions reductions that may be temporary. Without the effects of the pandemic, emissions reductions would be closer to a 42 percent decrease relative to 1990 and 6.1 percent decrease relative to 2019, and 6.7 MT CO2e per resident.
As a result of the historic 2019 partnership agreement with Valley Water and the City of Mountain View, Palo Alto secured funding to begin design of a salt removal facility at the Regional Water Quality Control Plant. The new infrastructure will improve the quality of recycled water produced at the plant and enable its expanded use for irrigation and industrial processes in both Palo Alto and Mountain View.
In January, the Office of Transportation took delivery of a new Yuba Spicy Curry e-bike. The long-tail cargo bike is used in lieu of a city pool car and carries supplies needed for bike rodeos, public engagement events, and site visits. In addition, it is available for all City staff to use and can serve a critical role in encouraging more City Staff to embrace getting around town by bike.
In June, the Office of Transportation staff forwarded, and the City Council approved, new California Environmental Quality Act (CEQA) thresholds that use Vehicle Miles of Travel (VMT) to determine the environmental impact of development. These thresholds will require development to reduce greenhouse gas emissions by reducing the amount of driving generated by the development.
Also in June, in addition to approving funding for the Palo Alto Transportation Management Association (TMA), City Council expanded the scope of the TMA’s publicly-funded programs from Downtown to the California Avenue business district. TMA programs support transit subsidies for low-income essential workers and provide ridesharing discounts for those working in the two business districts. Helping essential workers reduce single occupancy driving to Palo Alto reduces local greenhouse gas emissions.
Starting in November 2020 and in response to COVID-19 safety protocols, the Home Efficiency Genie launched a new virtual assessment platform to provide residents with a remote efficiency evaluation of their home. For a $49 fee, this new virtual, phone-based platform allows residents to walk through their home with guidance from the Genie technician to review and uncover inefficiencies, comfort concerns, and even health and safety issues. The Genie Home Electrification Readiness Assessment (HERA) was also redeveloped with a virtual option to help residents evaluate their existing electric panel to plan for adding electric equipment like heat pumps for water and space heating, induction cooking and EV charging.
City of Palo Alto Utilities (CPAU) promoted its regional EV charger rebate program available to workplaces. The program, CALeVIP (California Electric Vehicle Infrastructure Project) launched in December and is expected to result in approximately 200 new workplace EV chargers and 10 publicly available direct current (DC) fast chargers over the next 2 years.
The California Clean Fuel Rewards Program, partially funded by CPAU’s and other agencies’ Low Carbon Fuel Standard (LCFS) funds, launched November 17 and provides a $1,500 rebate for new EV purchases at participating dealerships.
The City completed large EV charger projects at six sites: Ellen Fletcher Middle School, Gunn High School, Green Middle School, SAP, Bryant Street Garage, and Cowper / Webster Garage. The EV charger projects at the three schools utilized the City's EV charger rebate program. The city installed 186 Level 2 ports and 7 DC Fast Charger ports, for a total of 193 new ports.
The City continues to incorporate electric vehicles whenever possible into the refuse service fleet. In 2020, three additional electric vehicles were acquired, including a wash truck used for commercial bin and cart wash services, a flatbed truck used for the newly expanded Clean Up Day program and for containers deliveries, and a rear loader truck that is used for the Clean Up Day program. Electrification of the refuse fleet reduces fuel usage, reduces greenhouse gas emission, and reduces noise during operation while supporting the S/CAP goals.
In June, established a new Compost Giveaway Station at the Eleanor Pardee Community Garden (851 Center Road. Driveway to Garden is on Center Road near Martin Street) for residents to pick up free compost for their gardens. Hours: Tuesday – Sunday: 9:00 am – 4:00 pm; Monday: CLOSED. The successful location provided 504 cubic yards of compost to the Palo Alto community in 2020.
A new Deconstruction Ordinance went into effect in July requiring all building permit applications submitted to remove the entire building to carefully deconstruct by material types and salvage for reuse instead of demolishing the building with heavy machinery. In 2020, 15 residential projects and 1 commercial project applied for the deconstruction permit. Staff is working closely with the project managers, contractors, and reuse organization to monitor the implementation of this ordinance to increase reuse and recycling of the building materials.
The City commenced work on a Sea Level Rise (SLR) Vulnerability Assessment, which will identify hazards and risks from sea level rise and rising shallow groundwater, as well as a Sea Level Rise Adaptation Plan to coordinate internal and regional SLR planning, project funding and public outreach.
In September, the City held a public webinar with Valley Water about local and regional sea level rise adaptation and planning projects that will benefit Palo Alto.
In partnership with the nonprofit Grassroots Ecology, the City held two public webinars about sea level rise: the first discussed the value of saltmarsh habitat and the second discussed king tides and sea level rise.
A model project was installed on East Meadow Circle that paired tree planting with green infrastructure. The project was initiated during a minor architectural permit review because the applicant wanted to satisfy tree replacement requirements off-site. A condition was negotiated to allow the applicant to pay for tree planting in the right-of-way. Utilization of the applicant’s backflow preventer and water meter was also negotiated in conjunction with planning for implementation. Staff excavated substandard soil, installed soil cells under the sidewalk to create root corridors and water storage, cut curbs for inlets into biofiltration soil, applied biochar (stable carbon), and installed trees. This project added 35 new trees in South Palo Alto, capture and storage for storm water, trained staff, and forged a valuable partnership with a corporate landowner.
City Council amended regulations in the Palo Alto Municipal Code for Accessory Dwelling Units (ADUs) and Junior Accessory Dwelling Units (JADUs) to promote the production of these housing unit types within the City. These unit types assist the community in meeting Housing Element goals and the City’s assigned regional target to provide more housing. (Ordinance 5507, Effective Date 11-26-2020).
City Council amended regulations in the Palo Alto Municipal Code to support transportation modes that reduce greenhouse gas (GHG) emissions. The amendments facilitate electric vehicle supply equipment (ESVE) installation and allow for eight additional bicycle parking spaces to replace one required vehicle parking space. (Ordinance 5504, Effective Date 9-24-2020)
Finalized a new Integrated Pest Management Policy(PDF, 303KB) which helps Palo alto continue its work of minimizing both the amount and toxicity of pesticides that are used on Palo Alto property.
The City launched a Southgate Beautification and Re-Greening Pilot Project with the local nonprofit Grassroots Ecology to maintain and update the bioretention areas for better performance. Improvements include amending existing soil to assist with drainage and plant health, replacing rocks with mulch, and exchanging current plants with native and drought-tolerant species.

2019

Palo Alto reduced greenhouse gas (GHG) emissions an estimated 38.2 percent* from 1990 levels, despite a population increase of 23.6 percent during that same time period. This equates to 7 metric tons of carbon dioxide equivalent (MT CO2e) per Palo Alto resident in 2019 compared to 14 MT CO2e per Palo Alto resident in 1990. The California Air Resources Board 2017 Scoping Plan Update recommends local government goals of 6 MT C02e per capita by 2030. (*In order to comply with the latest GHG inventory methodology, additional emissions sources were added to the 2019 GHG inventory that were not included previously. For a more direct comparison to 1990 levels, if we exclude these additional emissions sources the 2019 GHG reductions would be 41.2% or 6.7 MT CO2e per Palo Alto resident.)
The City of Palo Alto Utilities won the Smart Energy Provider award in recognition of its energy efficiency, distributed generation, and environmental initiatives that support a goal of delivering low-cost, quality, safe, and reliable electric service. This is the first year the American Public Power Association has awarded this designation to public power utilities.
On November 4, Palo Alto City Council adopted changes to Palo Alto’s Reach Codes, advancing an all electric requirement for new residential and commercial construction in 2020.
For the second year in a row, the City of Palo Alto received an A score for reporting on our climate-related data to the CDP (Carbon Disclosure Project). Palo Alto joins only 43 other cities - out of over 800 cities who report to the CDP - in the Leadership Scoring band for demonstrating best practice standards across adaptation and mitigation, setting ambitious but realistic goals and making progress towards achieving those goals, and for having strategic, holistic plans in place to ensure the actions being taken will reduce climate impacts and vulnerabilities of the citizens, businesses and organizations residing in our city.
In September, the City partnered with Hewlett Packard to complete one of the City’s largest solar array projects. Located on HP’s headquarters, the project uses 3,372 solar panels that are projected to generate 2,355 megawatt hours of energy, enough electricity to power 263 average Palo Alto homes for a year. The system is also expected to offset 1,700 metric tons of carbon dioxide.
Palo Alto Council approved a historic Partnership Agreement with the Santa Clara Valley Water District (Valley Water) that provides Valley Water an option to acquire about half of the treated wastewater produced by the Regional Water Quality Control Plant (RWQCP). The new agreement also funds a salt removal facility in Palo Alto which will allow increased use of recycled water from the RWQCP.
Palo Alto, in collaboration with the Santa Clara Valley Water District (Valley Water), developed a Northwest County Recycled Water Strategic Plan to identify the best potable and non-potable options for water reuse in the Regional Water Quality Control Plant (RWQCP) service area.
The City of Palo Alto’s Household Hazardous Waste (HHW) Program expanded its HHW Reuse Zone to divert waste of gently used products. Last year the HHW Station was able to divert over 5,000 pounds of materials with just a small pair of storage cabinets. The expanded HHW Reuse Zone now includes a larger shed to increase storage capacity for reusable materials such as paint, motor oil, and cleaning products.
As part of an ongoing effort to reduce waste in Palo Alto, City Council approved a Deconstruction Ordinance which will ban contractors from demolishing entire buildings by July 2020. The goal is for building materials to be reused or recycled, so workers will have to disassemble structures instead of wrecking buildings. Two of the largest components of landfill waste are food waste and construction and demolition (C&D) related materials. C&D materials represent more than 40% of Palo Alto debris that gets disposed in landfills.
Palo Alto City Council approved one of the region's strictest restrictions on plastics by banning plastic straw banning plastic straws, produce and meat bags, utensils, and other single-use plastic foodware items that bypass the recycling sorting process. Patient rooms at hospitals and clinics are exempt from the policy.
The City of Palo Alto’s Regional Water Quality Control Plant (RWQCP) replaced the City facility with the largest energy use - the sewage sludge incinerators - with a more environmentally-friendly Sludge Dewatering and Truck Loadout Facility. The updated treatment process will reduce climate-warming greenhouse gas emissions by approximately 15,000 metric tons of carbon dioxide equivalent per year– this approximates the carbon dioxide emissions of 3,000 passenger cars. The replacement technologies dewater the sludge and send it to farming areas to produce agricultural soil supplements.
Palo Alto City Council approved the Urban Forest Plan Second Edition. Record tree planting and pruning contributed to increase the value of benefits produced by 36,000 public trees to nearly $18 million annually.
