The adoption of China 6/VI vehicle emission standards, with effective compliance, will force significant mid-term and long-term reductions
in key health and climate pollutant emissions, bringing tremendous health benefits. The standards will reduce PM emissions by 37,000 metric tons, NOx
emissions by 3.3 million metric tons (figure 3), and avoid about 45,000 premature deaths in 2035 (Figure 4).

At the meeting, the U.S. and China also formally launched the “Race to Zero Emissions
” program, a "collaborative and friendly competition that encourages cities and metropolitan transit districts to incorporate new generations of advanced, non-polluting transit buses onto streets in the United States and China." And, in addition to the general agreement to pursue enlightened climate change and clean energy policies together in the G20, they pledged to work together this year to secure agreement there on improvements to fuel quality, energy efficiency, and emissions in the heavy-duty sector.
The progress being made by both of the world’s leading vehicle markets signals their utmost commitment to reducing air pollution from and the climate impact of motor vehicles. By approving an accelerated release of the China 6/VI emission standards, especially for heavy-duty vehicles, significant short-term and long-term health benefits will be realized.
