Carbon emissions from generating electricity for electric vehicles vary greatly across the individual US states

Green Car Congress

by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them.

Audi Hungaria starts operation of Europe’s biggest solar roof installation

Green Car Congress

The remainder is compensated by bio-gas certificates. In 2019 alone, Audi Hungaria saved more than 18,000 megawatt-hours of energy and avoided CO 2 emissions amounting to almost 5,750 tonnes by means of numerous efficiency measures. This is the third mechanism, which accounts for about five percent of the carbon emissions.

IEA: global CO2 emissions rebounded to their highest level in history in 2021; largely driven by China

Green Car Congress

Global energy-related carbon dioxide emissions rose by 6% in 2021 to 36.3 The rebound of global CO 2 emissions above pre-pandemic levels has largely been driven by China, where they increased by 750 million tonnes between 2019 and 2021. In 2021 alone, China’s CO 2 emissions rose above 11.9 billion tonnes. billion tonnes.
