Natural Gas Mobility not included in IEA WEI2018 report

Strikingly enough, a whole chapter on hydrogen filling stations and vehicles is included in the report, but nothing on Gas mobility. Natural gas vehicles and marine use of LNG as a fuel, which is rapidly growing as a way of overcoming the IMO sulphur cap is totally absent from the report. Hydrogen investments (USD 200 million investment in 2017 according to the report) has a chapter but Natural Gas for Transport (with LNG fuelled ships, bunkering, LNG & CNG fuelling stations, engines, etc) is not even mentioned. EVs, though are all over the report.
