National Institutes of Health (NIH) (.gov) https://pubmed.ncbi.nlm.nih.gov When secondary PM emissions were included, the EF was always significantly lower for the EV than ICEVs. The total PM10 EF of the EV (47.7-57.7 mg/V·km) was lower than those of the gasoline ICEV (56.5-70.5 mg/V·km) and diesel ICEV (58.0-72.0 mg/V·km). Since secondary PM particles are mostly of submicron size, the EFs of the PM2.5 fraction of the ICEVs (28.7-33.0 mg/V·km) were two times higher than those of the EV (13.9-17.4 mg/V·km). https://epha.org/electric-vehicles-and-air-pollution-the-claims-and-the-facts/ by Matteo Barisione | March 5, 2021 | Opinion Electric vehicles and air pollution: the claims and the facts A new article published today by Transport & Environment (T&E) explains that claims that electric cars make air pollution worse are wrong. Toxic emissions from tailpipes of diesel and petrol cars have caused tens of thousands of premature deaths each year. The health impacts of diesel emissions in the EU is well-known, especially after Dieselgate. The health impact of electric vehicles (EV) and its non-tailpipe emissions (brake, tyre and suspension) is a matter of some debate, following recent negative media coverage, e.g. in the United Kingdom and in France. Are we on the verge of an EVgate? It is actually the exact opposite, according to an article published on the T&E website. 1.EVs reduce pollution from brake and tyres On brake pollution, conventional internal combustion engine (ICE) cars mainly use disc brakes to slow the car down, which emits particle pollution. In contrast, EVs use “regenerative braking” as it restores braking energy back to the car’s battery to power the car. This process reduces the need to use the brakes and therefore reduces particle emissions. On tyre pollution, EVs have heavier weight compared to ICE cars and, according to some reports, this extra weight increases wear and thus particle pollution. Yet, EVs are mostly fitted with special tyres designed to cope with the heavier weight of batteries to ensure that they do not wear out too quickly. More studies are needed to measure particle emissions from tyres, especially from EVs, but all road vehicles, including heavy SUVs, are to blame for tyre pollution. 2. EVs reduce particle pollution Focusing on ‘primary’ particle mass (PM) emissions, i.e those particles which are emitted directly from the exhaust, tyres and brakes, should not lose sight of ‘secondary’ particle pollution. These particles form in the air due to other pollutants such as nitrogen oxides (NOx), hydrocarbons (HC) and ammonia (NH3) emitted from the tailpipe. Like primary particles these ‘secondary’ particles also contribute to PM2.5 (particles smaller than 2.5 microns) and PM10 (particles smaller than 10 microns) pollution, thereby causing poor air quality. According to a recent study by the Organisation for Economic Co-operation and Development (OECD), these secondary particles can contribute up to 29% of the total PM emissions of a car. Most importantly, the OECD study found that when all particle sources associated with cars are counted, including secondary particles, EV cars contribute less PM2.5 and PM10 than diesel or petrol cars. 3. EVs eliminate all toxic emissions from engines Switching from an ICE to an EV car eliminates all toxic tailpipe pollution, e.g. NOx, HC and carbon monoxide (CO). A harmful pollutant, nitrogen dioxide (NO2), is responsible for over 50,000 premature deaths per year in Europe. It causes respiratory and cardiovascular disease and can be a death sentence for those suffering from asthma. ICE cars also emit other pollutants, less known but toxic and cancer-causing chemicals including benzene (C6H6) and polycyclic aromatic hydrocarbons (PAH). Car makers themselves acknowledge that it is not possible to eliminate harmful emissions from the engines of fossil fuel vehicles. The only option is to switch from engines to electric motors, i.e. EVs. The sooner this happens, the sooner the air quality benefits will be felt across Europe. 4. Emissions from brakes and tyres must be regulated Expected improvements in air quality due to switching to EVs do not mean that non-exhaust pollution should be ignored. Particle pollution from brakes and tyres should be reduced in all vehicles as quickly as possible. A method for accurately measuring brake wear emissions is under development by the United Nations Particle Measurement Programme. Technologies for reducing brake wear emissions are already available. The EU-funded LOWBRASYS and REBRAKE projects succeeded in reducing particle mass emissions from brakes by over 50%. A French company Tallano has developed a ‘vacuum’ brake pad which is advertised to remove 85% of braking PM. This system can also be retrofitted and used by public transport such as buses or trams. The upcoming EU pollutant emission standard currently in preparation (called “Euro 7”), should set a brake particle limit for all vehicles regardless of their powertrain. This will drive innovation and adoption of low-emission brake technologies, reducing their contribution to air pollution for all vehicles. For tyre wear particles, the latest EU tyre labelling regulation (2020/740) requires the European Commission to develop a method for measuring tyre-wear emissions and subsequently assess the feasibility of adding abrasion and mileage information to tyre labels. Health and environmental NGOs now recommend that the Commission bans the sale of the most polluting and least durable tyres from the EU market since these have a disproportionately negative effect on air quality. It will beyond doubt improve air quality across Europe. In conclusion, EVs do not produce more pollution than fossil-fuelled cars. On the contrary, they eliminate emissions from engine exhaust and significantly reduce emissions from brakes. The evidence on tyres is more mixed. However, claims that EVs create more particle pollution due to tyres are misleading as they ignore their overall air quality benefits. Particle emissions should not be used as an excuse to slow down the transition to zero-emission mobility. Instead, regulations should address pollution from brakes and tyres to ensure that emissions from these sources are reduced for all road vehicles. 1 1 Quote Share this post Link to post Share on other sites

For EV, everything is connected to one large battery that supplies to internet accessing device also. It is by this design that EV could be more prone to be overtaken. A separate battery system was suggested by a cult kid, here in this forum. For accessory, including internet connection, there could be one lead acid battery.

That means electric vehicles, which weigh about 30 percent more than gas-guzzlers, are worse offenders when it comes to tire pollution.

Ecocharger + 1,474 DL October 10 (edited) European car makers are requesting the reduction of EV mandates for next year. https://www.transportenvironment.org/articles/tariffs-wont-save-european-ev-manufacturing-if-eu-drops-co2-targets-analysis "EU tariffs on EVs from China have had a mixed impact so far, according to T&E analysis of the EV-Volumes database. MG had its largest ever drop in BEV market share in Europe, falling from 4.1% share in August 2023 to 2.4% in August 2024, the research shows. BYD continued to expand its EU share though at a slower pace than before, growing from 1.6% in August 2023 to 2.9% BEV market share in the same month this year. Geely increased its market share from 1.3% in August last year to 2% in August 2024. Beyond EVs, the EU also needs a more coherent approach to its homegrown battery industry, T&E said. Domestic battery producers have experienced setbacks, driven by global market dynamics and cheap Chinese batteries. Unless action is taken, 59% of the battery production planned for Europe is at risk of not going ahead, T&E estimates, and would likely be scrapped. This would lead to a loss of billions of investment and close to 100,000 potential jobs. T&E called for an EU investigation into battery cells to enable trade defence measures."

The assertion that tire emissions are “1,000 times worse” than exhaust emissions is sensationalist and disingenuous. It is a misrepresentation of an Emissions Analytics claim that the weight of tire-wear emissions are 1,000 times greater than exhaust emissions per kilometer driven. To the admission of Emissions Analytics’ chief executive, this figure comes from a test performed on a car driven in such a way as to maximize tire emissions (“driven as crazily as you could, really pushed it”). Driving style is known to be the main factor of tire wear (Le Maitre et al., 1998), but the extreme measures adopted by Emissions Analytics are not representative of normal driving and would result in a tire lifespan of not more than 500km.
