Our Climate Assessment and Performance Report provides city officials, environmental advocates, users, and other stakeholders with performance-based metrics on emissions and electrification for passenger vehicle trips enabled by the Uber app.

The environmental impact of trips completed with Uber’s app matters. It’s our responsibility to report transparently on performance and take action to improve it. Our analysis shows that emissions resulting from the use of our platform are the most material component of Uber’s carbon footprint. This report, based on real-world use of our platform, helps provide greater transparency on our climate impact and helps us improve our efforts to support drivers’ fair transition to ZEVs and reduce emissions resulting from rides.

You can read our first report (2020) here and our second report (2021) here. Since our 2021 report, we have only published updates on this web page.

Metrics include the following:

• ZEV uptake by drivers on Uber (share of on-trip miles or kilometers completed in ZEVs), which measures our progress toward our goal of 100% zero-emission mobility on Uber globally by 2040
• Passenger carbon intensity, which measures the emissions resulting from every passenger mile

We have bold ambitions to reduce the passenger carbon intensity of trips and increase the use of zero-emission vehicles on Uber. Measuring what you manage and being transparent on progress are important steps along the journey.

Rides with the Uber app are one of many transportation options available to people who are looking for a ride. Trip choice depends a lot on various local market conditions. Our analysis of US National Household Travel Survey data shows that a higher per-household utilization of the most sustainable transportation modes (transit, walking, and biking) correlates with a higher utilization of ridesharing and other on-demand solutions.

Our first report, published in 2020, covered the US and Canada. We added major European markets to our second report, published in 2021. Many of the above metrics now cover all passenger trips completed with the Uber app globally. We’re aligned to regular reporting on climate emissions and other impact areas resulting from trips on Uber. We aim to expand the geographic scope of markets covered in the report over time for all our reporting metrics, including ZEV uptake and passenger carbon intensity.

We update all metrics at least annually and may update some metrics more frequently. We will release emissions metrics (like passenger carbon intensity) annually, aggregated by calendar year.

We use the term “zero-emission vehicle” (ZEV) the same way the California Air Resources Board (CARB) and Europe’s Transport & Environment (T&E) do: to refer to vehicles that produce no direct CO₂ emissions or other criteria air pollutants (such as NOx, particulate matter, CO₂, and SOx) from the on-board source of power. Regional variations should be considered at the reader’s discretion.

Drivers using Uber’s app use 2 types of ZEVs today: battery electric vehicles (battery EVs) and, very occasionally, hydrogen-powered fuel cell electric vehicles (FCEVs).

Of course, the “zero” in ZEV refers to no emissions from the proverbial “tailpipe” of the vehicle and not necessarily all the emissions that can be accounted for from production to disposal of the vehicle and its energy source. All accounted for, however, life-cycle analyses by independent experts show that “emissions over the lifetime of average medium-size battery EVs registered today are already lower than comparable gasoline cars by 66%–69% in Europe, 60%–68% in the United States, 37%–45% in China, and 19%–34% in India.”

Our Climate Assessment and Performance Report currently covers electrification and emissions metrics only for our Mobility business (ridesharing). We aim to include our Delivery and Freight businesses in this environmental sustainability report in the future.

To understand the steps we're taking across Delivery and Uber Freight, please consult Uber’s 2024 Environmental, Social, and Governance Report.

In Uber’s Environmental, Social, and Governance Report, you can find Uber’s emissions breakdown across Scope 1, 2, and 3 emissions, all of which have received limited assurance from an independent third party.
