Claim: New Study Confirms EVs Considerably Worse For Climate Than Diesel Cars (Anonymous, 2019-04-22)
Evidence (2023-04-04): European backsliding on electric vehicles is bad news for the climate [...] However, the past few weeks have seen the European Commission embroiled in a row with Germany, Italy and some other EU members over implementation of the 2035 deadline. This has been resolved, but only through a concession to Germany’s powerful automotive industry. New cars with internal combustion engines can continue to be sold after 2035, provided the engines use carbon-neutral fuels instead of diesel, petrol or compressed and liquefied gases. These are climate-damaging moves from a region that has so far led the world in policies for decarbonizing transport. [...] For the decarbonization of road transport to occur, the world will need what the Global Fuel Economy Initiative, a partnership on fuel economy and efficiency, called a "radical policy framework" (see go.nature.com/4381wvk). That means the removal of fossil-fuel subsidies and the mobilization of both public and private investment for the development of electric vehicles and their attendant charging infrastructure. It means tying the development of that infrastructure to renewable-energy-generation systems, while ensuring that supply chains are sustainable and providing recycling facilities for battery materials. And it means an international agreement must be reached on standards, so that the introduction of cleaner vehicles in one part of the world doesn’t mean old bangers being shipped off to pollute the environment elsewhere.

Evidence (2024-03-20): One of the most common false claims made against EVs is that they offer little or no climate benefit over conventional cars, due to the emissions associated with making their battery. [...] In an October 2023 article, the UK’s Climate Change Committee (CCC) says EVs "will be significantly cheaper than petrol and diesel vehicles to own and operate over their lifetimes". [...] A July 2023 article from the Sun claimed falsely that EVs "actually end up producing MORE pollution than petrol and diesel motors".
Claim: New Study Confirms EVs Considerably Worse For Climate Than Diesel Cars (Anonymous, 2019-04-22)
Evidence (2023-11-01): Other recent studies of electric cars in Germany have reached the opposite conclusion. One study found that emissions from EVs have emissions up to 43% lower than diesel vehicles. Another detailed that "in all cases examined, electric cars have lower lifetime climate impacts than those with internal combustion engines". [...] In other words, despite the headlines it generated, even ifo found that EVs ranged from being slightly better to somewhat worse than a diesel vehicle. [...] "EVs are not currently a panacea for climate change…lifecycle GHG emissions from electric vehicles can be similar to or even greater than the most efficient gasoline or diesel vehicles [in the US]."

Evidence (2024-05-09): Their batteries hurt the environment, but EVs still beat gas cars. Here's why [...] With all that's required to mine and process minerals — from giant diesel trucks to fossil-fuel-powered refineries — EV battery production has a significant carbon footprint. As a result, building an electric vehicle does more damage to the climate than building a gas car does. [...] If you look at the climate impact of building and using a vehicle – something called a "lifecycle analysis" – studyafter study has found a clear benefit to EVs. The size of the benefit varies – by vehicle, the source of the electricity it runs on, and a host of other factors – but the overall trend is obvious.

Evidence (2019-06-24): Misrepresents a complex reality: While some studies find that electric vehicles can be worse from a climate standpoint than the most efficient conventional (internal combustion engine) vehicles in areas where electricity comes mostly from coal, they generate less emissions than the average conventional vehicle. Electric vehicles become better for the climate as electricity generation becomes less carbon-intensive. [...] Other recent studies of electric cars in Germany have reached the opposite conclusion. One study found that emissions from EVs have emissions up to 43% lower than diesel vehicles. Another detailed that "in all cases examined, electric cars have lower lifetime climate impacts than those with internal combustion engines". [...] The general premise that EVs are not currently a panacea for climate change and that the life cycle greenhouse gas emissions from electric vehicles can be similar to or even greater than the most efficient gasoline or diesel vehicles is supported by other research, including the work of my group over the past decade. But it’s important to note that which technology comes out on top depends on a lot of things, especially:

Evidence (2024-01-02): From a climate perspective, a battery-powered vehicle is always superior to a combustion engine, even if the latter refuels with synthetic fuels in the future. This is the conclusion of a new study conducted by the ifeu Institute on behalf of the Federal Environment Agency, which analyses the environmental impact of cars, lorries and vans with different drive systems. It has now been scientifically confirmed: Electrically powered vehicles have clear climate advantages over combustion engines. This is true even if cars with combustion engines are powered by electricity-based synthetic fuels - so-called e-fuels - in the future. This applies equally to cars, lorries and light commercial vehicles. [...] The result: electric vehicles, which already have the lowest impact on the climate today, also perform better than combustion engines in the long term in other impact categories such as particulate matter pollution, acidification and ozone depletion. However, the remaining share of coal-fired electricity in the power mix still has a negative impact on the environmental impact of electric vehicles and worsens their balance in these impact categories.

Evidence (2023-12-01): The EPA and NHTSA propose model years 2018 to 2027 greenhouse gas emissions and fuel economy standards for medium and heavy duty vehicles.
Claim: New Study Confirms EVs Considerably Worse For Climate Than Diesel Cars (Anonymous, 2019-04-22)
Evidence (2024-02-05): The study analysed and compared the environmental and climate impact of passenger cars and commercial vehicles with conventional and alternative drive systems in detail, based on the entire vehicle life cycle. According to the results of the study, the climate benefit for electric passenger cars increases from 40 per cent when registered in 2020 to up to 55 per cent for cars registered in 2030 if renewable energies are rapidly expanded. The benefit to the climate will remain even if the proportion of e-fuels produced from renewable energy for cars with combustion engines increases significantly in the coming years. [...] The study also analysed the environmental impact of heavy goods vehicles. HGVs that use liquefied natural gas (LNG) have no advantages over diesel HGVs either for those registered in 2020 or those registered in 2030. Electric articulated lorries will have clear climate advantages for vehicles registered in 2030. Due to the high mileage of HGVs, the use phase is even more relevant than for passenger cars – meaning that emissions during vehicle and battery production are not as significant. Battery-electric articulated lorries or those with overhead lines and batteries will already have a 73 to 78 percent climate advantage over vehicles with combustion engines registered in 2030 if renewable energies are rapidly expanded; otherwise the figure will be 55 to 60 percent. These vehicles will also cause fewer greenhouse gas emissions than combustion engines in 2050.

Evidence (2024-02-26): But it is not only the rightwing press. In June, the Guardian published an article by the actor Rowan Atkinson in which he said he felt "duped" by EVs’ carbon claims and that the reality was "very different", citing Volvo research suggesting greenhouse gas emissions during production of an electric car are almost 70% higher than when manufacturing a petrol one. [...] The picture for electric cars will improve as power from the wind and the sun replaces gas and oil, reducing carbon emissions from generating electricity. Colin Walker, the head of transport at the Energy and Climate Intelligence Unit thinktank, said: "Even if you have a really dirty grid, EVs are still better for the environment. That will keep going as the grid gets cleaner and cleaner." [...] The scientific consensus is overwhelming: on any realistic like-for-like comparison a battery car will be cleaner than its petrol or diesel equivalent. Burning fossil fuels to make and drive electric cars will still cause emissions, but at a lower level than inefficient fossil fuel engines.

Evidence (2019-06-27): Transportation—including cars, trucks, and buses—is a major contributor to air pollution in the region, and is also the biggest source of global warming emissions in these states. Newer technologies like electric vehicles can dramatically reduce these dangerous local emissions. Moving to a cleaner transportation system isn’t just critical to reaching state climate goals; it will also help residents breathe easier and live healthier lives in the long term. "This study confirms the need to transition to cleaner forms of transportation, especially electric cars, buses and trucks and public transit," said Ken Kimmell, president of UCS, who served on Massachusetts Governor Baker’s Future of Transportation Commission. "While this transition will require significant investment, there will be a tremendous benefit in the form of improved public health, especially for our most vulnerable residents." The UCS study examined the impacts of pollution from on-road vehicles in Connecticut, the District of Columbia, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont and Virginia. The analysis is also available in Spanish.

Evidence (2021-03-18): One study suggests that CO2 emissions from electric car production are 59% higher than those for the production of ICE vehicles.2 [...] The British Government’s key 2018 publication The Road to Zero stated that EVs ‘have substantially lower greenhouse gas emissions than conventional vehicles, even when taking into account the electricity source and the electricity used for battery production. Assuming the current UK energy mix, battery electric vehicles produce the lowest greenhouse gas emissions of all the energy sources and fuels assessed, irrespective of vehicle type and operation’.17 The report estimated that in 2018 an electric car in the UK had total associated greenhouse gas emissions 66% lower than a petrol car and 60% lower than a diesel car.

Evidence (2023-08-09): Participants shared hesitations about increased use of electric vehicles (EVs) as part of a renewable energy transition. Some questioned whether EVs harmed the environment: "I think that with everything that’s in place over the last five years – and there’s good and bad, so all these people again, no one’s addressing the electric car in the energy and the minerals it depletes from the Earth. That’s an environmental issue." –Man, 50s, Southwest [...] Relatedly, many said EVs are no better for the environment than gas-powered vehicles or were unsure whether EVs are an improvement. "If you talk to people about switching to electric cars versus diesel- or gas-powered cars, you’re going to hear a lot of talking about how electric powered vehicles still produce a lot of waste, that they’re not as reliable, that they’re more expensive. Those are the questions that we’ve got and I think they’re valid questions because sometimes alternatives are not always better, and we know that producing electricity is probably going to produce waste no matter what unless we switch to a wind-powered society or something." –Woman, 20s, Southwest

Evidence (2019-04-22): According to the study directed by Christoph Buchal of the University of Cologne….. electric vehicles have "significantly higher CO2 emissions than diesel cars." That is due to the significant amount of energy used in the mining and processing of lithium, cobalt, and manganese, which are critical raw materials for the production of electric car batteries.
Claim: New Study Confirms EVs Considerably Worse For Climate Than Diesel Cars (Anonymous, 2019-04-22)
Evidence (2018-11-16): The EEA report ‘Electric vehicles from life cycle and circular economy perspectives’ reviews current evidence on electric cars’ impacts on climate change, air quality, noise and ecosystems, compared with conventional cars. Already now, across its life cycle, a typical electric car in Europe produces less greenhouse gases and air pollutants compared with its petrol or diesel equivalent. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time. The report confirms that the greenhouse gas emissions of electric vehicles, with the current EU energy mix and over the entire vehicle life cycle, are about 17-30 % lower than the emissions of petrol and diesel cars. However, as the carbon intensity of the EU energy mix is projected to decrease, the life-cycle emissions of a typical electric vehicle could be cut by at least 73 % by 2050.
Claim: New Study Confirms EVs Considerably Worse For Climate Than Diesel Cars (Anonymous, 2019-04-22)
Evidence (2024-05-22): Electric and hybrid vehicles can have significant emissions benefits over conventional vehicles. All-electric vehicles produce zero tailpipe emissions, and PHEVs produce no tailpipe emissions when operating in all-electric mode. HEV emissions benefits vary by vehicle model and type of hybrid power system. The life cycle emissions of an electric vehicle depend on the source of the electricity used to charge it, which varies by region. In geographic areas that use relatively low-polluting energy sources for electricity production, electric vehicles typically have a life cycle emissions advantage over similar conventional vehicles running on gasoline or diesel. In regions that depend heavily on conventional electricity generation, electric vehicles may not demonstrate a strong life cycle emissions benefit. Use the Electricity Sources and Emissions Tool to compare fuel-cycle emissions by vehicle type and state.
Claim: New Study Confirms EVs Considerably Worse For Climate Than Diesel Cars (Anonymous, 2019-04-22)
Evidence (2019-04-22): The Brussel Times reports that a new German study exposes how electric vehicles will hardly decrease CO2 emissions in Europe over the coming years, as the introduction of electric vehicles won't lead to a reduction in CO2 emissions from highway traffic. According to the study directed by Christoph Buchal of the University of Cologne, published by the Ifo Institute in Munich last week, electric vehicles have "significantly higher CO2 emissions than diesel cars." That is due to the significant amount of energy used in the mining and processing of lithium, cobalt, and manganese, which are critical raw materials for the production of electric car batteries. [...] German researchers criticized the fact that EU legislation classifies electric cars as zero-emission cars; they call it a deception because electric cars, like the Model 3, with all the factors, included, produce more emissions than diesel vehicles by Mercedes.
Claim: New Study Confirms EVs Considerably Worse For Climate Than Diesel Cars (Anonymous, 2019-04-22)
Evidence (2024-03-18): For plug-in hybrid electric vehicles, the real-world CO2 emissions were on average 3.5 times higher than the laboratory values, which confirms that these vehicles are currently not realising their potential, largely because they are not being charged and driven fully electrically as frequently as assumed. [...] For new plug-in hybrid electric vehicles (PHEVs) first registered in 2021, the real-world CO2 emissions were on average 3.5 times (4 l/100km or 100 g CO2/km) higher than the type-approval values, which confirms that these vehicles are currently not realising their potential, largely because they are not being charged and driven fully electrically as frequently as assumed. The Commission has already introduced changes to the calculation of the utility factor – the expected share of distance driven electrically – which is used to determine the CO2 emissions during the official test procedure. These changes will apply as of 2025 and may need to be further adjusted based on real-world data.

Evidence (2021-03-01): One of the oil industry’s favorite ways to try to attack electric cars was to say that they are just as polluting as gas-powered vehicles because they were powered by an electric grid that burns coal and natural gas. [...] Now the oil industry is using another argument to discredit electric vehicles: mining resources to build batteries is just as bad as the environment as burning petrol. [...] Transport and Environment (T&E), an NGO that looks into the impact of transport on the environment, has released a new study that looks to compare emissions from raw materials to produce electric cars versus gas-powered vehicles:
Claim: New Study Confirms EVs Considerably Worse For Climate Than Diesel Cars (Anonymous, 2019-04-22)
Evidence (2021-08-01): That finding comes from a white paper (.pdf) published by Georg Bieker at the International Council on Clean Transportation. The comprehensive study compares the lifetime carbon emissions, both today and in 2030, of midsized vehicles in Europe, the US, China, and India, across a wide range of powertrain types, including gasoline, diesel, hybrid EVs (HEVs), plug-in hybrid EVs (PHEVs), battery EVs (BEVs), and fuel cell EVs (FCEVs). (The ICCT is the same organization that funded the research into VW Group's diesel emissions.) The study takes into account the carbon emissions that result from the various fuels (fossil fuels, biofuels, electricity, hydrogen, and e-fuels), as well as the emissions that result from manufacturing and then recycling or disposing of vehicles and their various components. Bieker has also factored in real-world fuel or energy consumption—something that is especially important when it comes to PHEVs, according to the report. Finally, the study accounts for the fact that energy production should become less carbon-intensive over time, based on stated government objectives. According to the study, the life cycle emissions of a BEV driving around in Europe today are 66–69 percent lower than a comparable gasoline-powered car. In the US, that range is 60–68 percent less over its lifetime. In China and India, the magnitude is not as great, but even so, a BEV is still cleaner than a fossil-burner. China is at 37–45 percent fewer emissions for BEVs, and India shows 19–34 percent.
Claim: Marijuana is non-addictive, cures cancer, and grows brain cells (Anonymous, 2019-04-25)
Evidence (2019-04-25): While marijuana has been shown to be effective for pain management and cancer chemotherapy-related nausea, the drug does come with side effects and is not a cure-all. The claim that marijuana is non-addictive is untrue, while the claims that it cures cancer and grows brain cells are unsupported by current scientific evidence.
Claim: Marijuana is non-addictive, cures cancer, and grows brain cells (Anonymous, 2019-04-25)
Evidence (2024-05-07): "There's no two ways about it: [Cannabis] has anticancer properties," Wai Liu, a senior research fellow at St George's, University of London, told Live Science. "But the problem is, how do you translate that into the clinic — and that's the difficult question to address." Here's what we know so far about Mary Jane's cancer-fighting powers. [...] In the first trial, conducted in 2006, scientists showed that THC injections directly into the tumors of patients with brain cancer could safely and effectively inhibit their growth. The trial included just nine patients with glioblastoma. So, although these results were encouraging, the sample size of the study was too small to make any firm conclusions about the drug's safety and efficacy.

Evidence (2023-06-01): One of the top priorities among cannabis researchers is clarifying how the drug—which has been legalized for recreational use in 21 states and for medical use in 37 states—affects the developing brain. "I’m concerned by the increase in the number of people who are using cannabis at higher doses on a daily basis," said Nora Volkow, MD, director of the National Institute on Drug Abuse (NIDA). "Adolescents are more vulnerable to addiction, and once they are using compulsively, cannabis can interfere with memory and learning." In one study, 15% of people of all ages who used cannabis in the past 30 days met the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) criteria for cannabis use disorder, and rates specifically among youth ages 12 to 20 were significantly higher at 23% (Richter, L., et al., The American Journal of Drug and Alcohol Abuse, Vol. 43, No. 3, 2017).
Claim: Marijuana is non-addictive, cures cancer, and grows brain cells (Anonymous, 2019-04-25)
Evidence (2020-03-01): Not long ago, discussion was focused on whether cannabis caused cancer. A thorough review by the US National Academies of Sciences, Engineering, and Medicine found moderate evidence of no statistical association between cannabis use and the development of lung and head and neck cancers.1 Limited evidence of a statistical association was found between cannabis use and the development of nonseminomatous testicular carcinomas without good support for a causative effect. Throughout the past few years, the pendulum has swung to the point where many patients with cancer diagnoses are convinced, mainly by internet testimonials, that cannabis, particularly highly concentrated oils or tinctures of Δ9-tetrahydrocannabinol (THC) and/or cannabidiol (CBD), may actually cure their cancers. What is the basis of this belief?
