5 Diesel car sales have started to implode in major EU member states 5

6 Light-vehicle emission standards tightening further US implementation of Tier III light-duty emission standards began from MY 2017 onwards EU has began implementation of real-driving emissions (RDE) test requirements EU, Japan, Korea have adopted World Harmonized Light-duty Vehicles Testing Procedure (WLTP) China 6/VI emission standards surpass Euro 6/VI emission standards Euro 7 standards discussions have begun 6

7 China 6 emission standards are an ambitious step forward Emission limits are fuel neutral and more stringent than those in Euro 6 N 2 O emission limits Stringent evap. limits, innovative 48-hr test procedure, OBD and ORVR requirement OBD provisions largely based on CA OBD II with a few modification Modified RDE boundary conditions 7

11 A combination of regulatory tools and incentives is necessary to reduce transport emissions New Vehicle Policies Stringent tailpipe emission standards BS VI for on-road vehicles Stage V for non-road vehicles Stringent evaporative emission standards Strong compliance and enforcement program Promotion of electric drive Clean Fuel Policies Ultra-low sulfur fuels Stage I and II evaporative controls In-use vehicle emission control On-board diagnostics (OBD) based inspection and maintenance program Remote sensing or other in-use emissions testing program Scrappage of old (especially diesel) vehicles Diesel particulate filter (DPF) retrofits for BS III vehicles Demand management Restrictions on use of older/more polluting vehicles Additional fees for older/more polluting vehicles Low Emission zones (LEZ) 11

12 Transportation and Climate Change 12

13 The climate challenge for the global transportation sector has intensified in the past years. In 2003: Constrain transport sector emissions growth from 5 Gt direct CO 2 to 6 Gt by 2050, a 20% increase. In 2017: Reduce fuel lifecycle GHG emissions from 9.5 Gt CO 2 e to Gt in 2060, a 53 85% decrease. OECD/IEA. Energy Technology Perspectives (ETP) 2006 and [draft] 2017 models.

14 The 4DS includes some new policies; achieving a 2DS requires a transformation of the energy system; a B2DS goes even further. Source: OECD/IEA. ETP 2017 model.

15 Under a 2DS, any growth in transport GHG emissions is limited to regions outside the top 20 economies. Source: OECD/IEA. ETP 2017 model.

16 B2DS: A lot more buses, most of them BEV and PHEV 16

17 Global passenger cars fuel consumption standards 17

18 Global light-commercial vehicles (LCVs) fuel consumption standards 18

19 HDV efficiency standards projected to achieve 40% reductions HDV Fuel Economy + GHG Standards - ONLY 4 Nations: Japan, US, Canada, China Europe scheduled to Propose first-ever HDV CO2 in the spring of this year. India, Brazil, Korea, Mexico and others are also examining future standards. A key challenge is developing a simulation compliance model ideally harmonized across nations and regions. California has policies to promote ZEV buses and other segments. 19

20 The costs of EV battery packs have fallen faster than expected. Plug-in vehicle cost parity with ICEs could be reached in a few years. Nykvist, B., & Nilsson, M. (2015). Rapidly falling costs of battery packs for electric vehicles. Nature Climate Change, 5(4),

21 A ~70 g/km (NEDC) target by 2025 can be achieved cheaper if transitioning to electric vehicles earlier 21 Source:

22 If the new car diesel market share would decrease to 15% by 2025, a 70 g/km target could still be met 22 Source:

23 Passenger vehicle ZEV mandates spread around the world Government Target year Percentage of EV credits ICCT estimate of percent EV sales China % 3 4% California % 8% Quebec % 10% Europe % 30% 5 10% 15 20% China s New Energy Vehicle mandate is integrated into its existing fuel economy standards, an excellent first step but in need to substantial improvement in the next iteration of the standards. California forecasts only 8% EV penetration in 2025 due to credit multipliers which needs substantial enhancements to achieve a ~ 30% target by Quebec s policy is nearly identical to California s but with fewer credits Europe s policy currently only a proposal includes incentives for achieving substantial EV penetration levels but no penalties. We forecast substantial penetration levels due to major OEM commitments: VW (20 25% by 2025), BMW and Daimler (15 25% by 2025), Renault / Nissan (20% by 2020 depending on market conditions).

24 India Policy Landscape Policy Vehicle fuel efficiency standards Electric vehicles The first PV fuel efficiency standards: 130 gco 2 /km in 2017 and 113 gco 2 /km in 2022 The first HDV (>= 12 tons) fuel efficiency standards adopted on August 2017 Lower GST 1 rates for EVs FAME 2 scheme for hybrid and electric vehicles Central government s leading actions Progress new vehicle average fuel efficiency: 121 gco 2 /km 2015/current new vehicle average fuel efficiency: 650+ gco 2 /km A 12% tax rate for EVs (compared with 28% plus cess (1% to 15%) for petrol and diesel cars and hybrid vehicles) More than 176,473 vehicles participated (by the end of 2017) Extended through 2018, with the exact allocation for future years yet to be determined 10,000 EVs to be purchased for government cars Energy diversity 10% bioethanol blending targets 5% biodiesel blending targets ~3.3% on average across the country in 2016 The market for biodiesel (B100) is nascent CNG fleet More than 2.5 million CNG vehicles reported as of GST: good and service tax 2. FAME: Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles 24

25 Two scenarios for India on-road CO 2 emissions BAU Moderate Ambitious Fuel efficiency (FE) Zero emission vehicles (ZEVs) PV FE standard adopted HDV FE standard adopted 1-2% annual improvement between <1% in 2017 Up to 50% ZEV share in % annual improvement between Up to 100% ZEV share in 2050 Biofuel blending 1 2.5% bioethanol 0.5% biodiesel 10% bioethanol in % biodiesel in % bioethanol in % biodiesel in 2050 Electrical grid upgrade 820 gco 2 /kwh Target: 500 CO 2 g/kwh in The biofuel blending targets are set based on the sustainable feedstock capacity Target: 266 CO 2 g/kwh in

27 India Transport GHG stabilization scenario needs aggressive fuel efficiency (FE) policies AND full scale electrification by mid-century 1, CO2 emissions (megatons) Moderate FE Moderate ZEV Moderate bio-fuel Ambitious FE Ambitious ZEV Moderate BAU 400 Ambitious bio-fuel 300 Ambitious

28 Impact of mode shift, trip length and improved freight logistics Policy Assumptions Mode shift (the change in transportation activity 1 ) Reduction of urban trip length Logistic improvement Passenger vehicle to bus Passenger vehicle to rail ~6% ~13% ~22% ~4% ~5% ~6% Freight to rail 10% 20% 40% Passenger VKT 2 reduction Freight VKT 2 reduction 2% 3% 5% 3% 3% 5% Clean grid Low-carbon grid Reaching 50 gco 2 /kwh in Transportation activity in passenger kilometers or ton kilometers. 2. VKT: vehicle kilometers traveled. Source: 28

29 Urban planning and mode shifting required to bend the curve 1, CO2 emissions (megatons) Fuel efficiency standards Vehicle electrification Bio-fuel blending Cleaner grid Mode shift Urban planning BAU

30 Clean & low carbon mobility is an ambitious agenda Air Quality remains a major challenge around the world, but technology and policy progress is impressive. Transportation climate challenge is daunting, and time is running out. Huge potential in India to make progress on both fronts Increase policy ambition for emission and efficiency standards, along with vehicle electrification key Policy ambition needs to be matched by effective compliance and enforcement actions Technology can get us there most of the way, but needs complementary efforts on urban planning and mode shifting 30

32 ICCT mission and activities The mission of ICCT is to dramatically improve the environmental performance and efficiency of cars, trucks, buses and transportation systems in order to protect and improve public health, the environment, and quality of life. Non-profit research organization Air Pollution and Climate Impacts Focus on regulatory policies and fiscal incentives Activity across modes including aviation and marine Global outreach, with special focus on largest markets Slide 32

33 While emission standards were tightened, real-world NO x from diesel cars in EU remained high based on Chen and Borken-Kleefeld (2014)

35 ICCT kept analyzing global data trying to get a better picture of diesel vehicles NOx emissions 15 Euro 6/Tier 2-B5 LDDVs measured by PEMS 35

36 Government testing has confirmed earlier findings and points to numerous other defeat devices

37 Introduction of new RDE test procedure is an improvement but still masks part of the emissions NO x emission level (mg/km) 2,000 VW Jetta with defeat device (on-road) 1,000 VW Passat with defeat device (on-road) Euro 6 diesel average car (on-road) Euro VI average truck (on-road) : Conformity Factor 2.1 (RDE, on-road) 2020: Conformity Factor 1.5 (RDE, on-road) Euro 6 limit (NEDC, lab) Euro 6 gasoline average car (on-road)

38 Major reform of China Clean Air Law strengthens authority for compliance and enforcement Clear authority to enforce standards Recall authority is established for motor vehicles and off-road engines Clear authority of central and provincial environmental agencies (MEP and provincial EPBs) to impose large fines (1-3 times product value) for producing, selling and importing non-compliant vehicles Clear authority of the industry ministry (MIIT) to suspend or discontinue the production of violating vehicles/engines Clear authority of environmental agencies to perform compliance testing Authority of MEP and provincial EPBs to investigate and test newly produced and sold vehicles and engines Authority of local EPBs to perform random onsite and roadside emission inspection and testing, including remote sensing tests. Highlighted shared burden among government, industry, and consumers Manufacturers of vehicles and engines shall test their products to ensure emission compliance before introducing the products into commerce Manufacturers shall publish their emission compliance test result information to the public Manufacturers shall recall their vehicle/engine products if they are found not in compliance with standards due to design, manufacturing defects Consumers are prohibited from tampering/modifying emission control devises (incl. OBDs) 41

39 Fundamentals of controlling air pollutant emissions from motor vehicles New vehicle standards Fuel quality standards In-use vehicle emission control Technology neutral (but technology-forcing ) emissions standards for new vehicles. Must consider emissions from all mobile sources: on-road, offroad, marine, locomotives, aviation Limit values only as good as: - Compliance and enforcement - Real-world performance Systems Approach High fuel quality (especially low sulfur levels) enables advanced emission control technologies to be deployed in the fleet. Fuel quality compliance programs critical to prevent damage to engines and prevent misfueling Clean up legacy vehicles on the roads Comprehensive program includes: - Catching gross-emitters (I/M, remote sensing, maintenance, etc.) - Cleaner fuels - Scrappage/replacement programs - Retrofit programs - Complementary strategies (low emission zones, driver training, etc.) Not shown but also important: transportation demand management, modal shift, traffic optimization, and more
