Getting the data for China's emissions per kW/h, and usage by the new trains would likely be very difficult to do in the time constraints of news reporting.

However, an electrified rail network is more forward-looking as low-emission generating capacity can be brought online, or carbon sequestration technologies can be applied at existing plants.

Interest point to raise, but makes the kph snipe seem churlish in comparison.
