Are you planning to buy an electric vehicle for your next car?

Palo Alto's greenhouse gas emissions fell to 403,593 metric tons of carbon dioxide equivalent in 2025, down from 425,910 metric tons in 2024 and 49.5% below the 1990 baseline of 798,868 metric tons. Electric vehicles now make up 26% of the city's registered vehicles.

Why it matters

The primary driver of the decline is the rising share of electric vehicles, which matters for Palo Alto households weighing vehicle purchases and charging costs. Transportation still accounts for about 64% of total emissions, so vehicle choices remain the largest lever for household-level change.

Vehicle miles traveled rose from 597.7 million in 2024 to 614.13 million in 2025, even as per capita emissions reached 6.0 metric tons. Electric vehicles accounted for about 20% of trips starting and ending in Palo Alto in 2025, double the share recorded in 2024.

The players

Rincon Consultants

A consulting firm that performed Palo Alto's greenhouse gas inventory, supporting local climate planning and emissions tracking.

World Resources Institute

A research organization whose emissions-measurement protocols were used in Palo Alto's inventory, relevant to how cities track vehicle and electricity emissions.

C40 Cities Climate Leadership Group

A global network of city governments whose protocols guided the emissions calculations, shaping how cities measure vehicle-related pollution.

ICLEI - Local Governments for Sustainability

A municipal sustainability network whose protocols were applied in Palo Alto's emissions analysis, relevant to local climate targets.

The details

Emissions were calculated with a greenhouse gas inventory performed by Rincon Consultants, following protocols from the World Resources Institute, C40 Cities Climate Leadership Group and ICLEI. Electric vehicles now make up a growing portion of both registrations and new sales, and the city's carbon-free electricity portfolio accounts for nearly half of the reduction since 1990. Transportation emissions fell 22.9% over that period but still make up about 64% of the total.

1990: baseline year for the city's emissions reduction measurements.
2019-2020: emissions dropped nearly 100,000 metric tons as remote work rose during the Covid-19 pandemic.
2025: emissions fell to 403,593 metric tons and electric vehicles reached 26% of registrations.
Nov. 2, 2026: City Council is scheduled to discuss the emissions analysis.

The Home Front

Palo Alto's 49.5% reduction since 1990 places the city among peers tracking emissions-reduction goals, including Santa Monica, Cupertino, San Mateo County and Menlo Park, which has a 90% reduction goal. The shift toward electric vehicles is reshaping the local vehicle market, where 60% of 2025 new sales were electric.

If you are considering an electric vehicle, check local charging availability and compare current registration and new-vehicle sales trends in Palo Alto before deciding. Keep your vehicle's maintenance and charging records organized, since those documents will matter when you compare options or review costs with a licensed dealer or lender.

The takeaway

Vehicle choices are the biggest lever left for household emissions in Palo Alto, since transportation still makes up about 64% of the total. Track your own vehicle miles and compare charging costs before your next purchase, and consult a licensed electrician before any home charger installation.
