In the early 1990s, the California Air Resources Board (CARB) pushed for zero-emission vehicles.
A complete evaluation of an environmentally friendly vehicle’s impact must include its 11) _______________ from manufacturing, not just exhaust emissions. For battery electric vehicles, the battery’s production creates a significant initial carbon 12) _______________ that takes tens of thousands of miles to offset. Ultimately, policy measures such as tax breaks and access to bus lanes have helped overcome barriers like 13) _______________, though charging infrastructure in rural areas remains insufficient.
Questions:
: Discussion of battery-powered cars that produce zero tailpipe emissions, though the passage may highlight challenges like charging infrastructure and battery production.
IELTS passages on the environment love to contrast a technology's apparent benefits with its hidden drawbacks. Make sure you read carefully to see whether the author is presenting an advantage or a criticism.
Correct Heading: The urgent need for alternative transport solutions.
The European Union’s "Fit for 55" package mandates a 100% reduction in CO2 emissions from new cars by 2035, effectively banning the sale of new petrol and diesel vehicles. Similarly, China’s dual-credit policy forces automakers to earn positive credits by producing New Energy Vehicles (NEVs) or purchase them from rivals. These regulatory frameworks have redirected billions in R&D funding toward battery density, charging speed, and energy efficiency.
The increasing demand for electric vehicles (EVs) is driven by growing concerns about climate change and air pollution. As the world shifts towards a more sustainable future, EVs are becoming an attractive option for environmentally conscious consumers. With zero tailpipe emissions, EVs offer a cleaner alternative to traditional gasoline-powered vehicles.
A traditional engine that generates power by burning fossil fuels (petrol/diesel).
(The chemical reaction requires hydrogen from the tank and oxygen from the air).
At the more advanced end, BEVs—such as those manufactured by Tesla and Nissan—produce zero tailpipe emissions. Their environmental impact depends entirely on the source of the electricity used for charging. If powered by coal-fired plants, the net benefit diminishes; if powered by hydro, wind, or solar, the vehicle becomes genuinely carbon-neutral over its operational lifetime. FCEVs, meanwhile, convert hydrogen gas into electricity, emitting only water vapour. However, hydrogen production currently remains energy-intensive and often reliant on natural gas.
Environmentally friendly vehicles can be broadly categorised based on their propulsion systems and energy sources. The most prevalent types include Hybrid Electric Vehicles (HEVs), Plug-in Hybrid Electric Vehicles (PHEVs), Battery Electric Vehicles (BEVs), and Fuel Cell Electric Vehicles (FCEVs). Each offers a unique trade-off between emission reduction, driving range, and infrastructure dependency.
