- Vehicles account for 22% of greenhouse gas emissions in the UK, and vehicle emissions contribute to global environmental degradation. Stricter laws and regulations have been implemented to limit carbon emissions from new vehicles.
- Vehicle manufacturers have implemented various technologies and strategies to reduce emissions, such as particulate traps for diesel engines, improved catalytic converters, hybrid engines, and alternative fuels. Emissions of nitrogen, particulate matter, and carbon dioxide have been significantly reduced.
- While progress has been made, debates continue around implementing increasingly stringent emissions standards without incentives for manufacturers. Manufacturers argue standards may increase costs and prices without proper assessment of economic impacts.
Comparative Computational Modelling of CO2 Gas Emissions for Three Wheel Vehi...IJRES Journal
Quest for a greener environment and energy conservation has led a number of research studies to increase fuel economy and reduce emissions in developmental design of vehicles.This study illustrates how a vehicular body shape affects fuel consumption and gas emission. Solid models for two different tricycles were done and simulated using Solid works flow xpress, Mathematical models were applied to compare the rate of fuel consumption and gas emission between the simulated models. The result shows thatNASENI TC1 consumes less fuel and invariably emits less CO2 when compared with RFM 1.
A major part of the air pollution caused is due to the vehicular emission which is increasing at an alarming rate. The different types of vehicles like car, bus, truck etc. contribute a way as well as play a dominant duty in increasing air pollution. These vehicles find its running source mainly form the extracts of fossil fuels like petrol, diesel. The fuels undergo combustion to generate energy so as to support the vehicle for duty. The incomplete combustion of the fuels in the engine paves a way for production of products like the carbon monoxide, hydrocarbons and particulate matters. A high emission level is therefore a proved result. For the purpose of forcing the fuel to have efficient combustion and for reduction of the emission levels for reducing air pollution a wide range of processes are applicable. These include improvising engine design, fuel pre-treatment etc. Among these wide ranges of options available catalytic converter is found to be a better way for establishing an efficient combustion in the controller engine of the vehicle. Usage of noble group metal is an effective way for effective combustion like the platinum group metal serves way good for reducing the exhausts. With the help of secondary measures efficiency of the engine is improved as well. The techniques are still under development as because there are some limitations of the catalytic converters which are needed to be dealt with but the application of this technique has better achievement points as well.
A look at how automotive emissions legislation and the drive for energy sustainability are impacting the refining industry.
Both recent - and upcoming - legislation on automobile emissions has become the major change agent within this environmental arena. As with all legislation, regulation around emissions levels the playing field for all stakeholders in the automotive industry, effectively ensuring a competitive business climate. All participants must adjust their operations to comply with the latest regulations, leaving no-one at a competitive disadvantage.

STUDYING THE EFFECT OF CAR TECHNOLOGY ON CO EMISSIONS AND BENEFITS OF UPDATIN...IAEME Publication
This research compares CO emissions of old and new technology vehicles using field test. Benefits of replacement old passenger cars with new ones are estimated. Two representative cars are considered in field tests. Three factors are considered in the comparison; speed, Revolution per minutes (RPM), and relative humidity. Using mobile vehicle emission detector, more than 1000 readings are taken for each vehicle. Analysis proves that CO emissions from old technology vehicles are much more than that from new ones.
Carbon monoxide Content of Exhaust Emissions from Agricultural Tractor Engine...IJAEMSJORNAL
This study aims at contributing to the information buildup required for advocating the need for urgent reduction of environmental pollution by exhaust emissions from fossil fuel powered Engines in Nigeria. It was, concluded from the results obtained from the study that carbon monoxide content of the exhaust emissions of agricultural tractors are approximately forty nine(49) times higher than the recommended maximum level of 0.5 % vol CO (v/v) by the US Environmental Protection Agency (EPA). FIAT 70-666 contributed the largest content of 2.9 % vol of CO (v/v) while MASSEY FERGUSSON MF 375 contributed the least amount of 1.7 % vol of CO(v/v). Only the engine capacity had significant effect on the carbon monoxide content of the exhaust emissions of the agricultural tractors; the model/make selection did not significantly affect the CO content of their exhaust emissions.
Alternative Fuel Public Transport BusesIJERD Editor
The paper objective is to develop an analytical framework that will give us more insight into the
trends in emissions standards as well as technology development, and eventually translate these insights into a
sound investment decision making strategy. Public transport buses are high usage vehicles that operate in
heavily congested areas where air quality improvements and reductions in public exposure to harmful air
contaminants are critical. As such, they are good candidates for achieving both near-term and long-term
emission reductions. Cleaner and less polluting public transport buses based on alternative fuels are of
paramount importance if cities are to attain their ambitious emissions reduction targets. Decision making for the
investment in alternative fuel buses is dependent on future technological development and emissions standards,
and it is difficult, given the uncertainty in regards to both these factors.
Analysis of Emission from Petrol Vehicles in the Koforidua Municipality, GhanaIJERA Editor
Koforidua has seen its fair share in the increase in the number of cars on its roads over the past decade. This has resulted in progressive increase in traffic congestion on the roads and could lead to deterioration in the air quality. Exhaust gas emissions from a total of 104 vehicles were tested with an exhaust gas analyzer. Hydrocarbons (HC), Carbon dioxide (CO2) and Carbon monoxide (CO) were measured and compared with EU standards for gasoline vehicles and Auto Data Technical information. A series of algorithms developed using Microsoft Excel Spread Sheet were used to analyze the data collected. Out of the total number of cars tested, 74 and 80 cars passed the HC and CO tests respectively. 10 cars out of the total were rated as good under CO2 test. In total, 69.5% of the cars tested passed the various tests conducted and about 73 cars representing 70.2% of the cars tested were over 10 years and the emission standards for those years were flexible.

THE INFLUENCE OF CETANE NUMBER AND OXYGEN CONTENT IN THE PERFORMANCE AND EMIS...IAEME Publication
Waste plastic pyrolysis oil (WPPO) and ethanol are attractive renewable energy
sources, as ethanol has a high content of oxygen. However, for this particular study,
direct blending of conventional diesel, WPPO, ethanol and 2-ethyl hexyl nitrate (EHN)
was attempted. The purpose was, firstly, to improve the combustion, ignition quality,
performance and emission characteristics of the WPPO blends. Secondly, EHN has the
potential to reduce emissions of CO, CO2, UHC, NOX and PM. Thirdly, ethanol
improves viscosity and miscibility of biodiesel blends, besides increasing the oxygen
content of WPPO. Five mixing ratios were used in the following order,
50/WPPO25/E25, 60/WPPO20/E20, 70/WPPO15/E15, 80/WPPO10/E10 and
90/WPPO5/E5 for conventional diesel (CD), WPPO and ethanol and respectively.
However, for EHN the mixing ratio was determined by the total quantity of blended fuel
and put at 0.01 %. Complete miscibility was observed with no phase separation allowed
from the blended mixtures throughout the experiment. Performance and emission
characteristics of a stationary single cylinder water-cooled diesel power generator
were evaluated. The results obtained were compared carefully to ASTM standards and
discussed using tables and graph figure curves. The conclusion was that ethanol and
EHN can be used in diesel engine power generators as an alternative fuel to help
improve cetane numbers and to increase the oxygen content without or with
modification with WPPO blends. This is due to the densities 792 kg/m3
, 963 kg/m3
, 825
kg/m3 for WPPO, ethanol and EHN respectively, which are close to CD fuel at 845
kg/m3
. The addition of EHN, reduced emissions and improved engine performance so
that it equalled that of CD fuel

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

1. Vehicle maintainance
THE VEHICLE INDUSTRY AND ENVIRONMENTAL SUSTENANCEBackground
informationVehicles record 22% percentage of greenhouse gas (GHG) emissions in the U.K
(Environmental Protection). Road transport is one of the key sources of global
environmental degradation (Accut and Dodgson, 1996). With the overwhelming universal
concern for environmental protection, stricter laws have been formulated to limit the extent
of carbon emissions by the new car models being manufactured particularly in the U.S and
the U.K (Environmental Protection). The European Union in collaboration with national
governments have formulated and implemented regulations in relation to vehicle
manufacture and environmental protection (Roth, 2002; Environmental Protection). Car
engines, particularly diesel engines are the ones which cause much emission.The transport
emissions by the EU transport currently accounts for about 3.5% of the overall global
carbon dioxide emissions (Mulvey, 2007). According to Wrisberg (p.163), carbon dioxide
contributes the largest percentage to global warming, among other harmful emissions.
Adopting better transport forms with less impact on the climate is a very essential step that
is intended to protect our environment for future generations (Short and Kopp, 2005;
Hilden et al, 2004; Hine, 2004).Reduction of the environmental impact of emissions by car
manufacturersCurrently, the carbon gases emitted by vehicles are dependent on a voluntary
agreement between the auto manufacturers and the EU, unlike the U.S obligatory controls
(Roth, 2001; Perez et al, n.d; U.S Department of Transportation). The agreement is aimed at
reaching an average carbon dioxide emission of 120gram per kilometer for all new
passenger cars by 2012.The vehicle manufacturers have employed the exhaust-after
treatment system whereby the new diesel models are fitted with particulate traps that meet
the Euro 5 standards. Most of the latest commercial vehicles are utilizing Selective Catalytic
Reduction (SCR) in combination with a urea-based aIDitive to assist in reduction of nitrogen
emissions (one brand is ‘ AdBlue’ ).Manufacturers of trucks have reduced nitrogen and
particulate matter emissions by 86% and 95% compared to those trucks manufactured
from the early 1990s. Over the past 10 years, the exhaust emissions of trucks have reduced
by 35% despite the 30% increment of the work load. The emissions of 100 new model cars
are equivalent to the emissions made one old model car (dating back to the 1970s). This is a
significant advancement by the vehicle industry. Moreover, the particulate matter filters are
capable of reducing the emissions of particulate matter from the diesel vehicles by 99%.The
automobile industry is conducting research on how to advance the air conditioning system.
The Acea records indicate that the refrigerants which are lost from the air conditioning
2. systems are regarded among the contributors of the global warming effect. The research is
aimed at improving the tightness of the air conditioning system so as to improve air quality.
This will require improvement of the servicing processes and minimization of the losses of
refrigerants through design optimization. Otherwise, the industry could also consider
utilization of alternative refrigerants which have lesser global warming implications. These
two alternatives need thorough analysis and assessment in relation to cost implications.
The research will be based on the situations of different countries with regards to the
economic backgrounds and the differing climatic conditions.Acea sees the possibility of
developing a cost-effective and safe solution to the air-conditioning system. The
conservative system employing R-134a are perceived to be providing the best benefit-and-
cost outcomes owing to the fact that the society is not economically stable to provide
cheaper options of avoiding the green gas emissions. Thus the industry is only working
towards improving the R-134a air conditioning system which combined with the other
efforts will bring substantial environmental gains. The leakage rate has been reduced
through the improvement of technology and employment of better quality elements. For
instance, redesigning has occurred through lowering the permeation rates of hoses,
improving the connections, reducing the length of the flexible hoses and production of
“ hermetically sealed” designs. The R-134a system can now be recovered and recycled
when the vehicle is being serviced or disposed (ELV stage). Moreover, the dealer practice
and operator training have been improved so that drivers are acquainted with enough
background information about the vehicle and how to handle it carefully with regards to the
environment (Acea, 2003).The vehicle manufacturers are working hard to meet the
European emission standards in their respective states (Wrisberg, 2002, p. 163). The
penalties are so stringent that non-compliant vehicle manufacturers can not find market for
their vehicles in the European Union states. Wrisberg notes that these limitations are aimed
at reducing the consumption of fuel and the subsequent emissions of carbon dioxide. It is
fortunate that the current regulations are not applicable to already existing vehicles. There
is no mandate for specific technology to meet the required standards. All the new models
are required to meet the current standards. Thus car manufacturers are attempting to meet
the emission standards in order to find market for their vehicles (Resources Magazine;
Wrisberg, 2002).Previously, car manufacturers in the UK voluntarily agreed to employ a
more ‘ consumer-friendly’ color-coded label displaying carbon dioxide emissions on all
new cars from 2005, with a comprehensible indication of the amount of carbon dioxide
emissions. The new ‘ green label’ is aimed at giving consumers precise information about
the environmental performance of different vehicle types. Most European Union member
countries are in the process of developing labels that are consumer friendly(Resources
Magazine; EC, 1993).Vehicle manufacturers are making use of catalytic converters which
are essential for removing three dangerous chemicals-sulphur, nitrogen and carbon-from
exhaust gases. Vehicle engines have been redesigned to meet the environmental demands
(Orasch and Wirl, 1997; Advenier et al, 2002). Electronic ignition has been developed to
replace the conventional sources of power. Manufacture of plug-in electric vehicles which
use rechargeable battery packs. These packs can be charged from the electric grid or power
from regenerative braking and the internal combustion engine.Hybrid vehicles such as
3. hybrid electric vehicles which utilize two or more separate sources of power have been
developed. Such vehicles combine one or more electric motors and an internal combustion
engine. Some vehicle manufacturers are utilizing alternative sources of fuel in replacement
of the conventional pollutant fuels. The manufacture of vehicles which do not use
conventional fuels based on local availability and conditions is an ongoing process. Such
vehicles which utilize flexible-fuel and natural gases such as hydrogen are recommended
(Hill et al, 2006). Moreover, computerized management of engines is being encouraged to
boost efficiency (Proost and Dender, 2011).Manufacturers have invented water based
paints which have replaced solvent-based paints in order to reduce the emission of Volatile
Organic Compounds (VOC) that are basically crude solvents discharged from paintshops.
The amount of VOC emissions was reduced by 14.3% per vehicle (Hodac, 2011). Wrisberg
(p.163) states that VOC emissions, have the second largest percentage of global warming
effects and that automobile paint is the main source of these emissions.The European auto
manufacturers have substantially decreased the impact of vehicle emissions on the
environment (Hodac, 2003). Energy consumption and water, and emissions of carbon
dioxide and VOC per unit have all reduced. The results are basically dominated by the
volume of production at the industry level. There was a remarkable improvement in
environmental efficiency between 2005 and 2007. This was marked with reduction of
overall emissions and consumption at the industry as well. Manufacturers are consistently
working towards advancing the efficiency of energy in order to balance between consumer
and environmental demands. The ultimate energy consumption per vehicle manufactured
has reduced by 6.5%. The emissions of carbon were reduced by 5%. The manufacturers
worked successfully towards reducing the amount of waste produced by 4.8%. The
consumption of water per unit car was reduced by approximately 23%. This marked
significant development in the vehicle industry due to the utilization of re-circulation
inventions which permit water to be reused.Environmental DebatesAcea indicates that the
greatest challenge facing the vehicle industry currently is the European Commission’ s
introduction of more stringent limitations without any incentives for the new cars
manufactured. There have been several debates over the latest Euro V and Euro VI for
commercial vehicles and Euro 5 and Euro 6 standards for cars. According to Acea (2011),
the European Commission did not conduct a thorough assessment on the costs for the
industry to reach the expected targets. The new vehicles will definitely increase price levels
thus discouraging consumers from buying them. The automobile sector has made such
numerous efforts to ensure that the vehicles produced are environmental friendly
(Schipper, 2007). However, there are contentions that the Commission did not put their
recent regulations on thorough and transparent assessment about the implications of such
regulations before implementing them.The carbon dioxide emissions from vehicles have
indicated substantial reduction in the recent years from 21% of the total emissions in 1990
to 28% of total emissions in 2004. Currently, there are Euro standards which impose
limitations on carbon dioxide emissions from vehicles. The current Euro limitations for
petrol and diesel models on carbon dioxide emissions are a bit stringent. The European
parliament is regarding the introduction of obligatory carbon dioxide emission standards to
replace the voluntary commitments and labeling. The European Commission proposed new
4. law limitations on carbon dioxide emissions from cars in 2005. This proposed bill was more
stringent than that of the Western Union considering the fact that the emissions were
limited to the equivalent of 400kg CO2/MWh which would effectively preclude the
construction of any traditional coal-fired power plants.Pollutant emissions such as nitrogen
and particulate matter from cars, vans, buses and trucks were significantly reduced by the
recent exhaust after-treatment systems and engine technologies. This boosted air quality in
the cities and towns. Vehicle makers have continued to innovate ( Hodac, 2003). Hodac
(2003) proposed for the limitations set by the European Commission not to be implemented
unless there was a proper impact assessment that weighed the costs and effects of any new
target on market and environmental balances. According to Hodac (2011), objectives that
were unrealistic could threaten competitiveness and discourage carbon dioxide diminution
endeavors. Roth emphasizes that any regulation must regard the consequent cost and
benefit outcomes (2001). Instead of regulatory laws, the relevant authorities should provide
incentives for renewal of fleets in order to ensure protection of air as well as reduction of
overall costs (Hodac, 2011).The vehicle industry has argued that absolute replacement of
the older vehicles with the new models is enough to solve the issues of environmental
pollution rather than imposing obligatory limitations. Gasoline cars according to Acea and
the CAFÉ Programme’ s findings (Roth, 2001) indicate the potential of nitrogen and VOC
emissions reduction by 90% come 2020, even without Euro 5 limitations. Acea considers
the imposition of taxes for new cars by some governments as a wrong approach. The
industry is of the perception that member states should be supported to speed up the
renewal of fleet. AIDitionally, issuance of incentives by the government will accelerate the
removal of old models from the market and the demand for new cars will increase.
Incentives can be awarded in form of penalties or rewards so as to encourage the reduction
of pollution (Roth, 2002). Roth further asserts that economic based incentives depending on
policies are capable of allowing industries to react to reduction of pollution positively
through development of technology, modification of the product and process change.The
European Union entered into contracts with motor vehicle manufacturers with the aim of
reducing average carbon emissions from new cars. Nonetheless, the fact that traffic levels
are bound to increase over time washes away any optimism of carbon emission reductions
(Environmental Protection). Manufacturers should also aim at balancing the modal
transport facilities with the contemporary passenger demands so as to induce prospective
car users into adopting public transport facilities (Lopez-Pita and Robuste, 2003).
Moreover, IDEA, 2006) recommends a balance in the distribution of contemporary urban
transport demands to enhance the reduction in the number of motorized journeys and
length of travels.Regulatory organizations such as the United States Environmental
Protection Agency (USEPA) and the European Union have established the Portable
Emissions Measurement System (PEMS) for testing and assessing source emissions which
include cars, buses, trucks, cranes, and trains among others. These tests are aimed at
ensuring compliance, regulation and proper decision-making.Despite the advances in
vehicle and engine technology at reducing the implications of GHG emissions, the
insufficiency in meeting the emission goals set by the European Commission is still felt.
Proost and Dender (2011) remark that there is a high probability of the greenhouse gas
5. emissions increasing with time. There must be thorough assessment and planning with
respect to cost implications in order to meet the intended policies of shifting to more
sophiscated technology (Proost and Dender, 2011).Business opportunitiesEmphasis should
be made on adaption of other transport modes that are cost-and-benefit conscious and
regulation of the use of land to discourage the volumes of road transport in order to meet
the environmental protection goals(Proost and Dender, 2011; Perez et al,
n.d), .Development of technologies to detoxify the exhausts is imperative to emissions
control (Pacala and Socolow, 2004). Shifting to multimodal logistical facilities is another
way of promoting environmental-friendly transport modes (Schafer and
Victor). ConclusionThe European Union in collaboration with national governments have
formulated and implemented regulations in relation to vehicle manufacture and
environmental protection.The vehicle industry has argued that absolute replacement of the
older vehicles with the new models is enough to solve the issues of environmental pollution
rather than imposing obligatory limitations. The vehicle industry has made remarkable
attempts in reducing the greenhouse gas emissions by manufacturing new vehicle models
which have up-to-date features. The greatest challenge facing the vehicle industry currently
is the European Commission’ s introduction of more stringent limitations without any
incentives for the new cars manufactured. Various recommendations have been made in
line with reduction of the vehicle industry environmental pollution activities such as
adaption of other transport forms that are cost-effective and environmental-friendly. The
rising concern for environmental protection for the future generation will definitely see to
the reduction of global warming and climatic change.ReferencesAcutt, M. & Dodgson, J.
