This document discusses conflicting environmental priorities related to vehicle emissions. It outlines trends showing reductions in most air pollutants but increases in CO2 emissions from vehicles. Real-world vehicle emissions of CO2 are often higher than type approval tests. Remote sensing studies in Leeds and Zurich found diesel vehicles comply with Euro standards for NOx but exceed limits for PM10, with older diesels highest. Future analysis of real-world performance of Euro 6 diesels is needed given concerns about emissions deterioration and SCR system maintenance. Policy priorities need to consider matching powertrains to applications like petrol-hybrids for city driving.
Regulatory Outlook for real-world emissions - ICCTAutomotive IQ
The document discusses regulatory challenges around real-world vehicle emissions testing. It summarizes results from a meta-study of 15 diesel passenger cars that found average NOx emissions were 7 times higher than Euro 6 limits. It also discusses advanced emissions measurement technologies and trends, and various vehicle technologies that can help meet 2020 emissions targets, such as hybrid systems, electric vehicles, and fuel efficiency improvements.
Routes to Clean Air 2015 - Dr James TateIES / IAQM
This document summarizes the results of a remote sensing study of on-road vehicle emissions in the UK. It found that while Euro VI standards have reduced NOx emissions from heavy commercial vehicles, passenger cars still emit high levels of NOx. Diesel cars produced more NOx than petrol cars, and emissions varied between manufacturers. The document recommends implementing more stringent real-driving emissions regulations and testing, improving fuel taxation policies, and promoting sustainable transportation to further reduce vehicle emissions and improve air quality.
Routes to Clean Air 2015 - Petter HaugnelandIES / IAQM
Norway has been very successful in adopting electric vehicles (EVs), with over 66,000 all-electric cars sold, comprising 17.5% of new car sales in 2015 and 12.5% in 2014. This success is largely attributed to significant economic incentives provided by the Norwegian government since the 1990s, including no purchase taxes, VAT exemption, low annual road taxes, and other perks. A 2015 survey of over 7,000 Norwegian EV owners found that while range anxiety and lack of charging stations were initial concerns, EVs have proven practical even in Norway's cold climate and mountainous terrain, showing other countries that EVs can work as primary vehicles.

DMUG 2016 - Dr Ben Marner, Air Quality ConsultantIES / IAQM
The document presents results from real-world emissions tests of modern diesel vehicles. It finds that Euro 6 diesel cars emit significantly higher NOx than regulatory tests suggest, with a weighted average conformity factor of 5 across multiple studies. For heavy diesel vehicles, measurements show substantial reductions from Euro V to Euro VI standards of around 80%, but little improvement from Euro III to V. The document advocates uplifting older heavy vehicle standards to match Euro III levels and adjusting Euro VI standards to represent a 20% reduction from Euro III levels.

This document summarizes a presentation given at the 14th Annual Aimsun Users' Meeting about developing new meso- and micro-scale emission models for use in Aimsun traffic simulation software. The presentation introduces a new type of average speed emission model that uses regression relationships between average speed and emission rates from individual vehicle trips to provide more accurate predictions, especially at low speeds. It also describes a fast, simple instantaneous emission model implemented in the Aimsun API based on vehicle specific power. The models show improved verification compared to observed emissions data and will allow more reliable air pollution simulations accounting for local traffic and fleet conditions.

The document summarizes the results of real-world emissions testing of over 1200 vehicles. It finds that nitrogen oxide (NOx) emissions are on average 4 times legal limits, and real-world fuel economy and carbon dioxide emissions are 29% and 41% higher than official figures, respectively. Performance differs significantly between models certified to the same standard. Upcoming regulations may improve but not solve the problem. The need for an independent, real-world emissions standard is greater than ever.

Monitoring co2 emissions from new passenger cars in the euAutoblog.it
The document summarizes data on CO2 emissions from new passenger cars in the EU in 2012. Key points:
- The average CO2 emissions from new cars in the EU in 2012 was 132.2 gCO2/km, a decrease of 3.5 gCO2/km from 2011.
- Diesel vehicles made up 54.9% of new registrations. Average emissions decreased for both diesel and petrol vehicles compared to 2011.
- Alternative fuel vehicles increased their market share and saw a decrease in average CO2 emissions compared to 2011. Pure electric vehicles have 0 gCO2/km tailpipe emissions.
16.00 Updates to CURED and CREAM Emissions Models.pdfIES / IAQM
- The document describes updates made to the CURED and CREAM emissions models, which predict emissions of NOx, PM, and NH3 from road vehicles.
- For CURED, the updates include incorporating projections of electric vehicle uptake from the Transport Analysis Guidance, and a new approach for calculating non-exhaust PM emissions. Comparisons show CURED estimates of NOx and PM emissions are slightly lower than the Emissions Factors Toolkit.
- For CREAM, updates include incorporating the same electric vehicle projections as CURED and updated ammonia emission factors. Comparisons show higher estimated ammonia emissions than the previous version, especially with inclusion of cold starts.
Report: Mind the Gap 2015 – Closing the chasm between test and real-world car...Nicola Barozzi 🚘✔
The system of testing cars to measure fuel economy and CO2 emissions is utterly discredited. This report analyses the gap between test results and real-world performance and finds that it has become a chasm, increasing from 8% in 2001 to 31% in 2012 and 40% in 2014. Without action this gap will grow to nearly 50% by 2020.
Mercedes cars have the biggest average gap between test and real-world performance, with real-world fuel consumption exceeding test results by nearly half. None of the improvement in emissions measured in tests of Opel/Vauxhall cars since 2008 has delivered improvement on the road, and their real-world fuel economy is actually getting worse. Just a fifth of the apparent improvement in emissions from the launch of the Mark 7 VW Golf (Europe’s best-selling car) have been achieved on the road.
This report definitively shows current systems for vehicle testing of fuel economy and CO2 emissions don’t work and the proposed introduction of the new WLTP test seems likely to deliver limited and only temporary improvements. Systematic changes to the way cars are tested, regulated and taxed are needed to ensure cars are decarbonised on the road and not just in laboratories. The technologies to reduce emissions are available – what is missing is a robust policy framework to ensure these are delivered.

Energy efficiency trends in transport in the EULeonardo ENERGY
After 6 years of regular decrease, the energy consumption of transport in the EU has been rising again since 2013, at the same rate as before the financial crisis. It has become the most energy-consuming end-use sector, responsible for 31% of the final energy consumption in the EU27 in 2019. The energy transition in transport lags far behind the other sectors. However, some countries are performing better than others.
During this webinar, our expert speakers present an evaluation of the energy efficiency trend in the European transport sector since 2000. The following key questions are addressed:
What has been the overall trend in transport energy consumption in the EU and other European countries since 2000?
What are the main drivers for the energy consumption variation in transport, and in particular for the energy savings?

Uses of vehicle emissions remote sensing data for emission factor developmentIES / IAQM
Vehicle emissions remote sensing (VERS) is a method to measure pollutants in vehicle exhaust through roadside sensors. VERS data can be used to develop emission factors and estimate emissions. The document discusses how VERS emission factors can be calculated in units of grams per second or grams per kilometer based on vehicle speed and acceleration. It also outlines applications of VERS data such as verifying national emission inventories, examining effects of vehicle manufacturers, and characterizing European vehicle fleets. Remote sensing is a useful tool that complements other emissions measurement methods.
This document summarizes key findings from the International Energy Agency's Energy Technology Perspectives report regarding pathways for low-carbon transport. It discusses how transport energy use could increase 75% by 2050 without action, and the need to avoid, shift, and improve transport to reduce emissions. Electric vehicles, plug-in hybrids, and fuel cell vehicles may account for nearly three-quarters of new light-duty vehicle sales by 2050 in a low-carbon scenario.
Green NCAP is a new consumer program that rates vehicles on their environmental performance. It aims to provide ratings to help consumers choose greener vehicles and stimulate manufacturers to improve environmental credentials. Vehicles are tested using various driving cycles in the lab and on the road to evaluate pollutant emissions, energy efficiency, and other factors. Ratings are on a 0-5 star scale across two indices for clean air and energy efficiency. The inaugural tests showed improvements from Euro 6d vehicles but limitations in fully assessing battery electric vehicles.
Most European member states have voluntarily developed car CO2 labels based on the EU energy label format. The document analyzes different label designs and whether ratings should be absolute or relative. It recommends harmonizing labels across countries to an absolute 7-band A-G scale for simplicity, but including best-in-class information for comparison. A composite label displaying both absolute ratings and best/worst in class is suggested. Examples of existing country labels are also presented.
GFEI in Ukraine presentation for Moldova 10.07.18Oleg Tsilvik
The document summarizes a Global Fuel Economy Initiative project in Ukraine. It provides an overview of the project's goals, which include reducing Ukraine's dependence on imported fuel, slowing climate change by lowering carbon emissions, and improving air quality and public health. The summary describes how the project established a national baseline by collecting and analyzing vehicle registration data to determine average fuel economy and emissions levels. It also identifies issues with the data quality and gaps. The baseline analysis found that Ukraine's average fuel economy and emissions are higher than global averages, but have been improving in recent years. The project aims to continue supporting Ukraine in meeting international fuel economy targets through capacity building and policy recommendations.
Non-exhaust Particulate Emissions from Road Transport: An Ignored Environment...OECD Environment
Airborne particulate matter produced from the wearing down of brakes, tyres, and road surfaces, as well as the resuspension of road dust constitute a little-known but rising share of pollution from road traffic. These non-exhaust emissions can have significant negative impacts on public health and are expected to comprise the majority of all particulate matter from road traffic as early as 2035.
Projections from the OECD report Non-exhaust Particulate Emissions from "Road Transport: An Ignored Environmental Policy Challenge" show that electric vehicle uptake in future years will not reduce non-exhaust emissions and may even increase them. On 7 December, our team of experts discussed the nature, causes, and consequences of non-exhaust emissions and how policy makers can address this emerging policy issue.

This document provides an overview of using liquefied petroleum gas (LPG), also known as propane, as a vehicle fuel. It discusses the reduced fleet operating costs of $10,000-$15,000 per vehicle over the vehicle's lifetime from lower fuel prices and reduced maintenance compared to gasoline or diesel. Propane also produces lower emissions that are better for the environment. The U.S. government provides various funding and tax incentives for converting vehicle fleets and fueling infrastructure to use propane. Fleets of all sizes from various industries have successfully converted their vehicles to use propane.
"A big data approach for investigating the performance of road infrastructure...TRUSS ITN
“Using truck sensors for road pavement performance investigation” is a research project within TRUSS, an innovative training network funded from the EU under the Horizon 2020 programme. The project aims at assessing the impact of the condition of the road pavement unevenness and macrotexture, on the fuel consumption of trucks to reduce uncertainty in the framework of life-cycle assessment of road pavements. In the past, several studies claimed that a road pavement in poor condition can affect the fuel consumption of road vehicles. However, these conclusions are based just on tests performed on a selection of road segments using a few vehicles and this may not be representative of real conditions. That leaves uncertainty in the topic and it does not allow road mangers to review the current road maintenance strategies that could otherwise help in reducing costs and greenhouse gas emissions from the road transport industry. The project investigated an alternative approach that considers large quantities of data from standard sensors installed on trucks combined with information in the database of road agencies that includes measurements of the conditions of the road network. In particular, using advanced regression techniques, a fuel consumption model that can take into consideration these effects has been developed. The paper presents a summary of the findings of the project, it highlights implications for road asset management and the road maintenance strategies and discusses advantages and limitations of the approach used, pointing out possible improvements and future work.

Efforts to reduce the emissions from car travel have so far been hampered by a lack of specific information on car ownership and use. The Motoring and vehicle Ownership Trends in the UK (MOT) project seeks to address this by bringing together new sources of data to give a spatially and disaggregated diagnosis of car ownership and use in Great Britain and the associated energy demand and emissions.
Data from annual car M.O.T tests, made available by the Department for Transport, will be used as a platform upon which to develop and undertake a set of inter-linked modelling and analysis tasks using multiple sources of vehicle-specific and area-based data. Through this the project will develop the capability to understand spatial and temporal differences in car ownership and use, the determinants of those differences, and how levels may change over time and in response to various policy measures. The relationship between fuel use and emissions, and the demographic, economic, infrastructural and socio-cultural factors influencing these will also be tested.
Consequently, the MOT project has the potential to transform the way in which energy and emissions related to car use are quantified, understood and monitored to help refine future research and policy agendas and to inform transport and energy infrastructure planning.

Social networks, i.e. the circles of people we are socially connected to, have been recognised to play a role in shaping our travel and activity behaviour. This not only has to do with socialisation being the purpose of travel, but also with enabling mobility and other activities through the so-called social capital. Another theme in the literature connecting social environment and travel behaviour is social influence, i.e. the investigation of how travel behaviour can be affected by observation or comparison with other people. Research about the impact of social influence on travel choices is still at its infancy. In this talk, I will give an overview of how choice modelling can be used to investigate the relationships between social networks, travel and activities. I will touch upon work that I have done so far, in particular I will describe my applications of the Multiple Discrete-Continuous Extreme Value (MDCEV) model to frequency of social interactions as well as to allocation of time to different activities, taking the social dimension into account. In these studies, I make use of social network and travel data collected in places as diverse as Switzerland and Chile. I will also discuss ongoing work making use of longitudinal life-course data to model the impact of family of origin and the “mobility environment” people grew up in on travel decision of adults. Finally, I will outline future plans about modelling behavioural changes due to social influence using the smartphone app travel data that are being collected in Leeds within the “Choices and consumption: modelling long and short term decisions in a changing world” (“DECISIONS”) project.

Abstract: In the national railway revolution in Japan, the passenger division was divided into 6 companies by regions. They operate trains and own/manage the rail track (vertical integration system). On the other hand, vertical separation was introduced into freight companies, therefore, freight companies have to access rail track owned/managed by passenger companies. The Japanese regulator regards track access transactions between passenger companies and freight companies as private business.
In the vertical separation system, freight companies cannot get access to the slots required and efficient allocation of rail track cannot be achieved. The vertical separation is a very significant issue in railway policy and freight transport policy in Japan. In the presentation, causes and possible solutions to the issue will be shown.

Presentation from NORTHMOST - a new biannual series of meetings on the topic of mathematical modelling in transport.
Hosted at its.leeds.ac.uk, NORTHMOST 01 focussed on academic research, to encourage networking and collaboration between academics interested in the methodological development of mathematical modelling applied to transport.
The focus of the meetings will alternate; NORTHMOST 02 - planned for Spring 2017 - will be led by practitioners who are modelling experts. Practitioners will give presentations, with academic researchers in the audience. In addition to giving a forum for expert practitioners to meet and share best practice, a key aim of the series is to close the gap between research and practice, establishing a feedback loop to communicate the needs of practitioners to those working in university research.

18. RECOMMENDATIONS
18
▶ RDE regulations
▶ Sooner rather than later i.e. before Jan 2017
▶ Transparency in RDE testing
▶ In-service RDE testing (deterioration emission controls, SCR dosing, DPF removal)
▶ Independent + Open data
? Environmental labelling for CO2 and air quality pollutants ? A marketing incentive ?
▶ Shift inTax landscape to include NOX penalty
▶ Price fuel e.g. Belgium Diesel +10cts per litre 2016-2017
▶ VED
▶ Company car Benefit in Kind (BiK) tax
▶ Car free City centres
▶ Sustainable mobility Active travel Green space
▶ Noise
19. And finally…. improving air quality
