European cities are well aware that transport is a leading emitter of GHGs (Greenhouse Gas, a 33% share in 2019, according to the IEA , International Energy Agency), so decarbonisation of public transport systems is a key component of net-zero carbon strategies.

“ E-car batteries are a key technology to implement rapid electrification of transport and achieve the targets of the Paris Agreement . Their production will generate billions of euros in revenue and create thousands of jobs.

Batteries are unanimously seen as key drivers of the energy transition .

With buyers facing unusually long delays between ordering and receiving new cars, car manufacturers are pivoting to make key components, including semiconductor chips and lithium-ion batteries .

A new report by Gothenburg, Sweden-headquartered carmaker Volvo shows that electric vehicles must still overcome big environmental challenges, even as they reduce greenhouse gas emissions .

Sales of battery-electric vehicles (BEVs) are increasing as consumers and automakers alike benefit from European government subsidies for electric vehicles.

Battery electric vehicles (BEVs) are starting to win market share in Europe, as consumers opt for cleaner technology and lawmakers strengthen emissions rules for automakers in a bid to bring down pollution levels.

Electric cars are rapidly moving from the periphery of the automotive sector in the European Union to the mainstream.

Low-carbon mobility is essential to reduce greenhouse gas emissions. In Valladolid, Spain, hybrid buses use electricity in the city centre and are connected to a smart city platform which monitors how often they charge and how much.

Greenhouse gases decreased by 23% between 1990 and 2016, said the third report on the state of the “Energy Union”, which tracks the EU's transition to a low-carbon society.

A new research conducted by world leading emissions experts is painting a rather gloomy picture. Due to stronger economic growth, global greenhouse gas emissions have hit a new record high of 37 billion tonnes of dioxide in 2017.

Grass could be used to produce biofuels. The advantage of using grass crops is that they can be grown in marginal lands that would otherwise not be used .

Vehicles seats are normally made of polyurethane foam, a thick material that is expensive to recycle and ends up in dumping sites or being incinerated.
