Uber’s Climate Assessment and Performance Report

The environmental impact of trips served by Uber’s platform matters. It’s our responsibility to measure that impact by evaluating data gathered from the real-world use of Uber, share the results publicly for greater transparency, and act to improve our climate performance.

April 2024 update: This page reflects metrics for trips completed by zero-emission vehicles (ZEVs) from the beginning of the first quarter of 2021 to the end of the first quarter of 2024. Note that this report includes information related only to Uber’s Mobility business (ridesharing).

“The road to zero emissions requires transparency and being accountable for progress year after year. Uber is proud to be the first mobility platform to measure and report on emissions from customers’ real-world use of our products.”

Dara Khosrowshahi, CEO, Uber

ZEV drivers

Globally, about 143,000 ZEV drivers a month, on average, actively used Uber’s app in Q1 2024. That’s more than double the same period a year earlier.

Metric: Average monthly active ZEV drivers on Uber, by quarter, since Q1 2021, the start of the first full calendar year after announcing our sustainability goals. Drivers using Uber’s app are counted as active in a given month if they’ve completed at least one trip in that calendar month.

Note: as of Q1 2024, we’ve updated this metric to cover all markets where Uber’s mobility app operates; previous versions of our reporting covered only trips in Canada, the US, and 7 countries in Europe.

ZEV trips

In Q1 2024, ZEV drivers provided nearly 66 million tailpipe-emissions-free trips using Uber, globally. This is nearly twice the number of ZEV trips completed on Uber during the same period a year earlier.

Metric: Number of trips arranged on the Uber app and fulfilled by ZEV drivers, by quarter since Q1 2021.

Note: as of Q1 2024, we’ve updated this metric to cover all markets where Uber’s mobility app operates; previous versions of our reporting covered only trips in Canada, the US, and 7 countries in Europe.

ZEV uptake

In Q1 2024, ZEV drivers completed 9.0% of all on-trip miles in Europe and 8.2% of all on-trip miles in Canada and the US. That represents increases of 2.2 and 3.2 percentage points, respectively, compared with the same period a year earlier. These results correspond with figures published in a recent BloombergNEF report that show ZEV uptake by Uber drivers in Europe is happening about 5 times faster than that of drivers in the general public.

Metric: Share of on-trip miles completed in ZEVs compared with all on-trip miles arranged by the Uber app, by quarter since Q1 2021. Canada, US, and European benchmark data is as of 2023 and is sourced from the International Energy Agency. “BEV” refers to battery electric vehicles.

Note: as of Q1 2024, we’ve updated the ZEV uptake metric for Europe to cover all markets where the Uber mobility app is used in Europe.

Passenger carbon intensity

In 2023, each mile that a passenger traveled on Uber resulted in an average generation of 191 grams of CO₂ in Europe (or 119 grams of CO₂ per kilometer) and 307 grams of CO₂ in the US and Canada (or 192 grams of CO₂ per kilometer). Compared with 2021, this passenger carbon intensity metric fell 16% in Europe and 15% across the US and Canada.

Metric: Passenger carbon intensity, or the estimated grams of CO₂ per passenger mile traveled, is a climate and efficiency metric used by Uber—and, increasingly, governments and companies around the world. In the case of ridesharing, or any on-demand mobility service, emissions produced by any “deadhead” miles—vehicle miles traveled without a passenger—are factored into the calculation.

For more details about how we calculate passenger carbon intensity, go to our methodology document. Note that significantly lower average fuel economy for vehicles on Uber in Europe versus the US and Canada explain most of the difference in carbon intensity in these 2 geographies. While the composition of vehicles that drivers use on Uber’s app in Europe is more efficient, with a higher proportion of ZEVs and hybrids, more-stringent fuel economy reporting standards in the US also contribute to this discrepancy. In addition, we lack access to sufficient input data to calculate passenger carbon intensity for trips completed in European markets before 2021.

Note: as of Q1 2024, we’ve updated the passenger carbon intensity metric for Europe to cover all markets where the Uber mobility app is used on the European continent; previous versions of our reporting covered only 7 European countries.

Insights and deep dives


Frequently asked questions

  • 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 webpage.

  • 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 are taking across Delivery as well as Uber Freight, please consult Uber’s 2024 Environmental, Social, and Governance Report.
