China's Central Government has injected 750 million yuan ($121.56 million) in subsidies to boost low-carbon transport in the past two years.

Triggered by this, the transport sector has attracted about 20 billion yuan ($3.26 billion) in investment for energy conservation and carbon emissions cuts since 2011, the Ministry of Finance said Thursday.

These efforts have saved energy equivalent to 158,000 tons of standard coal and eliminated 699,000 tons of carbon emissions annually, according to a statement on the ministry's website.

One method, for example, involves promoting drop and pull transport, which is more efficient than the traditional mode, as an engine vehicle separates from its loaded trailers upon arrival and connects with other trailers full of freight for a new destination.

China plans to expand its national road network from 173,000 km at the end of 2012 to 401,000 km by 2030, the National Development and Reform Commission and the Ministry of Transport said Thursday.
