Uber 的氣候評估與成效報告
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.
November 2023 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 third quarter of 2023. Note that this report includes information related only to Uber’s Mobility business (ridesharing).
「在實現零排放的路上，我們要保持透明的資訊及負責任的態度，公開每年的進展。Uber 是首個根據使用者使用產品的實際情況數據，衡量並報告碳排放情況的交通平台，我們引以為傲。」
Uber 執行長 Dara Khosrowshahi
ZEV 行程
In Q3 2023, ZEV drivers provided more than 38 million tailpipe-emissions-free trips using Uber in the US, Canada, and Europe.* This is nearly 2 times 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.
ZEV 使用率
In Q3 2023, 9.6% of all on-trip miles in Europe* and 6.5% of all on-trip miles in Canada and the US were completed by ZEV drivers. That represents increases of 2.5 and 2.4 percentage points, respectively, compared with the same period a year earlier. ZEV uptake by drivers using Uber’s app is nearly 6 times higher in Europe and over 7 times higher in Canada and the US than that of drivers in the general population, according to the most recent published government figures (see links below).
Metric: Share of trip miles completed in ZEVs compared with all trip miles arranged by the Uber app, by quarter since Q1 2021.
Note that between Q2 and Q3 2023, we adjusted our methodology for identifying EVs in Europe to improve accuracy (see page 2 of our methodology doc for details), indicated by a dotted line between Q2 and Q3 2023.
Canada and US benchmark data is as of 2022 and is sourced from the International Energy Agency. Note that “BEV” refers to battery electric vehicles. European benchmark data is as of Q2 2023, sourced from the European Commission's European Alternative Fuels Observatory, and only for those European countries indicated below.*
Passenger carbon intensity
In 2022, each mile that a passenger traveled on Uber resulted in an average generation of 147 grams of CO2 in Europe* (or 92 grams of CO2 per kilometer) and 322 grams of CO2 in the US and Canada (or 201 grams of CO2 per kilometer). Compared with 2021, this passenger carbon intensity metric fell 25% in Europe and 11% across the US and Canada. In the US and Canada, 2022 carbon intensity levels continued a 2-year reduction trend, recovering from 2020 highs concurrent with the COVID pandemic to an all-time low since we began measuring more than 6 years ago.
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 carbon intensity, see 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 our fleet composition 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. Also note that we lack access to sufficient input data to calculate passenger carbon intensity for trips completed in European markets before 2021.
常見問答
- Uber 最新的《氣候評估和成效報告》有什麼內容？
Our Climate Assessment and Performance Report provides city officials, environmental advocates, users, and other stakeholders with performance-based metrics on emissions and electrification progress, and efficiency metrics for passenger vehicle trips enabled by the Uber app.
- 為什麼要發布這份報告？
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 estimates show 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, provides 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.
- 您在《氣候評估與成效報告》中使用的關鍵評估指標是什麼？
Metrics include the following:
- EV use 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
- Carbon intensity, which measures the emissions resulting from every passenger mile
- 本報告將如何改善 Uber 行程的碳排放強度？
We have bold ambitions to reduce the carbon intensity of and increase the use of zero-emission vehicles for trips facilitated by Uber until we realize a fully zero-tailpipe-emissions mobility platform around the world by 2040. We cannot reach that goal without knowing where we stand today.
- Do riders take trips with Uber instead of using lower-carbon options like public transit?
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 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.
- 您會評估全球其他國家或地區的相同資料嗎？
Our first report, published in 2020, covered the US and Canada. We added major European markets to our second report, published in 2021. We’re committed to regular reporting on climate emissions and other impact areas resulting from trips on Uber and plan to expand the geographic scope of markets covered in the report over time.
- 您多久更新一次這些指標和報告？
We update all metrics at least annually and may update some metrics more frequently, as available. We will release emissions metrics (like passenger carbon intensity) annually, aggregated by calendar year.
- 「零排放車輛」是什麼意思？
我們使用「零排放車輛」(ZEV) 一詞的方式，與加州空氣資源委員會 (CARB) 和歐洲交通運輸環境 (T&E) 相同：此詞是指車輛不會從車載式電源直接排放 CO2 或其他標準空氣污染物 (例如 NOx、顆粒物、CO₂ 和 SOx)。
目前，使用 Uber App 的職業駕駛使用 2 種 ZEV 車款：純電車 (BEV)，以及極少數的燃料電池電動車 (FCEV)。
當然，零排放車輛中的「零」是指車輛的「尾管」沒有排放，不一定是指車輛從生產到廢棄及其能源的所有排放。然而，根據獨立專家所做的生命週期分析顯示，「目前登記的中型純電車在其生命週期內的平均排放量比同級燃油車低 66% 至 69%，美國為 60% 至 68%，中國為 37% 至 45%，印度則為 19%–34%。」
- 您會衡量 Uber Eats、外送和 Uber Freight 業務的影響力嗎？這些業務目前在 Uber 業務中佔很大比例？
In June 2023, we announced our first-ever sustainability commitment for our Delivery business (Uber Eats) to reduce unnecessary packaging waste and delivery trip emissions globally to zero by 2030 and 2040, respectively.
Our Climate Assessment and Performance Report currently covers electrification and emissions metrics only for our Mobility business (ridesharing). We plan to include our Delivery and Freight businesses in this environmental sustainability report in the future.
- Does Uber disclose Scope 1, 2, and 3 emissions, and, if so, where would they be found?
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.
This page and the related Climate Assessment and Performance Reports and Environmental, Social, and Governance Reports (“the report”) contain forward-looking statements regarding our future business expectations and goals, which involve risks and uncertainties. Actual results may differ materially from the results anticipated. For more information, please see our reports.
*In 2020, we set a goal of reaching 50% of trip kilometers completed in battery EVs in 7 European capitals: Amsterdam, Berlin, Brussels, Lisbon, London, Madrid, and Paris. For this reason, all mentions of “Europe” for the metrics reported here refer to all passenger mobility trips completed in the country-level markets corresponding to these 7 European capitals: the Netherlands, Germany, Belgium, Portugal, the UK, Spain, and France, respectively. Further details can be found in our SPARK! Report.
