1990, Richard Sandor, the father of international carbon trading, strongly pushed the US Congress to pass the Clean Air Act Amendment and started the limit and trading of sulfur dioxide. In the past 20 years, the effect has been remarkable, and the emission of sulfur dioxide has been reduced by 50%, which has produced substantial positive effects.

In 2003, Sandor founded CCX Company with years of experience in operating sulfur dioxide market. However, since the United States has not signed the Kyoto Protocol, there is no mandatory ceiling. Therefore, Sando chose CCX trading based on voluntary carbon reduction, and achieved remarkable success after many difficulties.

In 2004, Sandel founded ECX and established a carbon trading platform in Europe.

Sulfur dioxide trading and carbon trading are essentially gas emission reduction transactions and can learn from each other. If there can be people like Sando in our country, and the country formulates relevant laws and creates a mandatory ceiling, I believe that the prospect of China's carbon market will be very broad.

Finally, I hope I can help you.
