3 . When it comes to lowering our carbon emissions (排放), it seems that nothing is simple. Electric vehicles (EVs) act as an example of potential greenwash. “They seem very attractive at first sight,” writes The Next Web in a report. “When we look more closely, it becomes clear that they have a substantial carbon footprint.”
The rare earth metals and costly minerals included as essential ingredients in EV batteries are not renewable. What’s more, their extraction (提炼) is often anything but green.
So the question is: is it worth it? Just how much emission reduction can EVs justify? Luckily, a life cycle assessment has been done to give us some answers.
“A life cycle analysis of emissions considers three phases,” writes The Next Web. “the manufacturing phase, the use phase, and the recycling phase.” In the manufacturing phase, the battery is to blame. “Emissions from manufacturing EV batteries were estimated to be 3.2 tons of carbon dioxide (CO2), 1/4 of those from an electric car, 13 tons of CO2. Those were bigger than emissions from gas cars, 10.5 tons of CO2.” If the vehicle life is assumed to be 150,000 kilometers, emissions from the manufacturing phase of an electric car are higher than gas cars.”
In the use phase, the source of electricity the consumer is using to power their car comes into play in a major way. “To understand how the emissions of electric car vary with a country’s renewable electricity share, consider Australia and New Zealand,” continues the report. “In 2018, Australia’s share of renewables in electricity was about 21%. In contrast, the number in New Zealand’s was about 84%. Electric car emissions in Australia and New Zealand are estimated at about 170g and 25g of CO2 per km respectively. As a consumer, our car is only as green as our country’s energy mix.”
Finally, in the recycling phase, we look at vehicle dismantling(拆除), vehicle recycling, battery recycling, and material recovery. “The estimated emissions in this phase, based on a study, are about 1.8 tons for a gas car and 2.4 tons for an electric car. This difference is mostly due to the emissions from battery recycling, which is 0.7 tons,” shows in the report. “While electric cars cause more greenhouse gas emissions than gas cars do, it's important to note the recycled batteries can be used in subsequent batteries. This could have significant emissions reduction benefits in the future. For complete life cycle emissions, the study shows that EV emissions are 18% lower than gas cars.”
So here’s the takeaway: EVs are greener. Maybe they’re not as green as we thought. There’s certainly room for improvement. But the real challenge lies in speeding the global energy transition toward greener energy-production.

If you’ve recently taken a flight from a major UK airport, then you may have noticed that more people are protesting air travel expansion and encouraging people to fly less. This is part of a larger environmental movement sweeping across Europe. Known as Flygskam or “flight-shaming”, the movement is encouraging people to stop taking flights as a means of transport and use more environmentally friendly transportation where they can.
The aviation (航空) currently accounts for about 2% of global emissions (排放) and is one of the fastest-growing polluters. Even worse, unlike most other sources of pollution, air travel results in pollutants released high up in the atmosphere.
Earlier this year, the UK government promised to reduce the UK’s emissions to “net zero” by 2050. However, according to projections from some researchers, emissions from the aviation could more than double by then even if planes become substantially more fuel-efficient. So, it’s unclear whether flying will be included in the UK’s target.
It’s hard to say exactly how big the movement is becoming, but Flygskam has become popular in social media. The number of Swedes taking the train for domestic journeys has risen by 8% this year as plane journeys inside the country have fallen. Clearly, Flygskam is having a measurable impact on people’s transport choices. Some people, however, have been critical of the movement because they say that it places blame or feelings of embarrassment onto the passengers when it is really the airlines and industries associated with it who should feel guilty for the impact that they are having on the planet.

10 . It’s a known fact that emissions (排放物) from gas-powered vehicles are harming the atmosphere. In response to this, Porsche, the German sports car company, began producing e-fuels at a pilot plant in Chile last year. Currently, the fuel will be used only in sports cars at Porsche’s performance and experience centers.
E-fuels are made by passing electricity through water. The electricity separates the hydrogen and oxygen from water. The hydrogen is then mixed with CO₂ to produce a liquid e-fuel, which can be produced using many renewable energy sources, such as solar and wind power. E-fuels follow the chemical structure of gasoline, making it possible for gas-powered cars to run on e-fuels almost without any change.
E-fuels can help ease the transform away from gas-powered cars, for those who may not be able to afford electric vehicles (EV). It will also help to reduce waste by keeping gas-powered cars in service, instead of throwing them away prematurely. Additionally, the use of e-fuels will not require new facility to be built unlike EVs. Existing gas stations and cars will be able to stay in use, which is already a big saving.
Despite the many benefits, opinions differ on whether e-fuels are truly eco-friendly. E-fuels are widely said to be nearly carbon neutral (碳中和), although an independent study indicates that e-fuels release the same amount of CO₂ as gasoline. Since e-fuels are still being developed and tested, their true impacts are still unknown. Meanwhile, e-fuels are very expensive to produce, partly due to energy loss during production. Unfortunately, only about half of the energy used in producing e-fuels is actually transformed into fuel. Additionally, only about 16% of the energy used in e-fuel production is actually used to power the car. Whereas, about 70% of energy is preserved when powering an EV. Even though the use of e-fuels will preserve existing facility, it will still take time and money to integrate it into everyday life. Currently, the price of e-fuels is nearly double the cost of regular fuel.
E-fuels are still a work in progress. Though opinions are divided on e-fuels, with more testing and development, they have been considered another way to help fight against the climate crisis. “There are currently more than 1.3 billion vehicles with combustion (内燃) engines worldwide. Many of these will be on the roads for decades to come, and e-fuels offer the owners of existing cars a nearly carbon-neutral alternative. With the e-fuels pilot plant, Porsche is playing a leading role in this development,” said Michael Steiner, member of the Executive Board for Development and Research at Porsche AG.
