Sulfur Hexafluoride (sf 6) Emission Estimates for China: An

Sulfur hexafluoride (SF 6) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, SF 6 emissions from China were inventoried for 1990–2010 and projected to 2020. Results reveal that the highest SF 6 emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the SF 6 production sector (each about 10%).

Greenhouse gas emissions by China - Wikipedia

Greenhouse gas emissions by China are the largest of any country in the world both in production and consumption terms, and stem mainly from coal electricity generation and mining. When measuring production-based emissions, China emitted over 12 gigatonnes CO2eq of greenhouse gases in 2014; almost 30% of the world total. This corresponds to over 7 tonnes CO2eq emitted per person each year, slightly over the world average and the EU average but less than half the second largest emitter of greenho

On 17 December 2018, the European Parliament and the European Council decided to tighten the CO2 limits yet again: Car emissions are to be reduced by a further 37.5 percent from 2021 to 2030 – a demanding goal. For Mercedes-Benz Cars, this would correspond to average emissions of 65 g CO2/km per vehicle in 2030 – this would amount to consumption of 2.4 l of diesel or 2.7 l of petrol/100 km
