What are the national standards for energy-saving vehicles and low-carbon vehicles, such as how much exhaust gas is emitted and what fuel is used?

China's Ministry of Science and Technology has put forward new fuel consumption standards. The carbon dioxide emission per kilometer is 1, 61g. According to the calculation that 1 liter gasoline is equivalent to 2.3 kilograms of carbon dioxide, it is equivalent to consuming 7 liters of gasoline per 100 kilometers, which is slightly lower than the American standard.

How should China realize low-carbon transportation fuel? First of all, there must be a standard evaluation method. Seven units, including China National Institute of Standardization, Energy and Transportation Innovation Center and COFCO, have jointly studied and drafted two national standards for "low-carbon fuel", among which "Principles and requirements for assessment of greenhouse gas emissions in the life cycle of transportation fuel" has been drafted and widely solicited. The Report and Audit of Greenhouse Gas Emissions from Transportation Fuel Life Cycle is in the drafting stage, and the draft standard is expected to be completed in early July. Two draft national standards for "low-carbon fuel" are planned to be submitted to the National Standardization Committee before August. These two national standards can not only help enterprises to evaluate the greenhouse gas emissions in the life cycle of transportation fuels, but also help government decision-making departments at all levels to formulate relevant policies and regulations according to the evaluation results.
