|WLTP (Worldwide Harmonized Light vehicles Test Procedures)|
|Worldwide Emission & Fuel Economy/CO2 Regulation Timeline (Passenger Cars & Light Duty Trucks)|
|08 May 2020||Emission Standards||EU||1.An initial assessment, with regard to the development of post-Euro 6/VI emissions standards for light duty and heavy duty vehicles, was published by the European Commission at the end of March 2020.
2.Test procedures to measure CO2 emission by passenger vehicles and light commercial vehicles were updated.
|08 May 2020||WLTP||World||The GTR 15 (WLTP)  reflecting amendment 5  was globally registered on 23 September 2019.|
|12 March 2020||Fuel Economy/CO2||EU||Regulation 2020/22 , published in January 2020 contains updates on monitoring and reporting requirements for light commercial vehicles those are type approved in a multi-stage process, as well as on the calculation of the CO2 emissions targets for these vehicles for the years 2021 to 2024.|
|27 January 2020||Fuel Economy/CO2||EU||Regulation 2019/1859, which applied from 10 November 2019, details the data that will be used to assess the representativeness of the reference CO2 emissions for the calculation of the CO2 emissions targets for new heavy duty vehicles to be reported to the European Commission by manufacturers.|
|17 January 2020||Fuel Economy/CO2||USA (Federal)||The EPA is currently prevented from enforcing the Phase 2 standards for trailers. This relates to a stay of these provisions granted by the US Court of Appeals in response to a petition filed by the trailers' manufacturers which argues that the EPA lacks the authority to regulate trailers, as they are not self-propelled vehicles.|
|14 January 2020||Fuel Economy/CO2||USA (California State)||In December 2019, CARB published an update to suspend the implementation of the Phase 2 trailer standards for model years 2020 and 2021.|
|2 December 2019||Fuel Economy/CO2||China||In July 2019, new fuel consumption standards for both motorcycles and mopeds were published. These standards will be mandatory for new type approvals from 1 July 2020 and for all new vehicles from 1 August 2021.|
|19 November 2019||Emission Standards||EU||A corrigendum to regulation 2018/1832 was published in October 2019 and amends the date for the last registrations for stages BH and BI as shown in Table 2.|
|11 November 2019||Fuel Economy/CO2||USA (California State)||In a Federal Rule published in September 2019, the EPA withdraws California's Clean Air Act Preemption Waiver. By this rule, the federal fuel economy and CO2 emissions standards for passenger cars and light duty trucks is enforced in all States.|
|08 November 2019||Fuel Economy/CO2||USA (Federal)||1) Part of the provisions contained in the SAFE proposal was issued as a final rule in September 2019. A national programme for fuel economy/GHG standards will be applied and enforced in all States. This rule is applicable from 26 November 2019.
2) As of October 2019, the amendments to the fuel economy standards for model years 2021 to 2026 are still being finalized; they are due to be published in a separate final regulation.
|24 September 2019||Fuel Economy/CO2||EU||1.Monitoring and reporting of CO2 emissions and fuel consumption for heavy duty vehicles will be required starting on 1 January 2019.
2.CO2 emissions targets for heavy duty vehicles will be in place from 2025.
|30 August 2019||Emission Standards||EU||1) The European Commission prepared a proposal in June 2019 that will amend the main Euro 6 regulation, 715/2007, introducing the conformity factors within this regulation and therefore allowing the discrepancy between real driving emissions and emissions determined under laboratory conditions. The type approval procedure and the introduction dates for the Euro 6 stages will remain unchanged.
2) According to a note from the European Commission published in May 2019, the implementation dates for stages BH and BI will be amended to 31/8/2020
|15 August 2019||Fuel Economy/CO2||USA (California State)||1. In July 2019, CARB reached a voluntary framework agreement with four major vehicle manufacturers on the standards for light duty vehicles up to 2026MY.
2. The final approval to the phase 2 standards for heavy duty vehicles was filed in February 2019 and the standards are effective from 1 April 2019.
|08 August 2019||Emission Standards||China PC & LDT||1. Early introduction of the China 6b standards in Beijing, Shenzhen, Tianjin and Guangdong province was reported.
2. The information about adjustments made to the RDE test emissions values during the "extended" ambient conditions was added.
|02 August 2019||Emission Standards||India||The final AIS-137, Part 3  was published in April 2019 and covers the test procedures required for type approval and conformity of production in respect of the BS VI standards, including requirements for the OBD (on-board diagnostics) system, in-service conformity and test procedures for hybrid electric vehicles (HEV) except details of RDE test.|
|26 July 2019||Emission Standards||China HDV||1. The China VI standards are being implemented in two phases, VIa and VIb. The implementation dates and difference between two stages are reported.
2. The procedure and environmental conditions for the vehicles' on-road emissions test are updated according to the final China standards.
3. Requirements for crankcase emissions are updated.
4. From the VIb phase, all vehicles will have to transmit the required OBD and emissions data to the Environment Authority and the manufacturers for their full life.
|03 July 2019||Emission Standards||EU||1) The latest updates of regulations for measuring CO2 emissions with WLTP cycles were described in the regulation 2018/2042 and 2018/2043 published in December 2018.
