SINGAPORE'S carbon tax is a good first step towards a carbon-free future, but it is not doing enough to encourage the cars, trucks and ships that ply its streets and seas to be more energy-efficient, a top executive at Royal Dutch Shell told The Business Timesyesterday.

In this sense, the energy giant is keen to work with local authorities on making the transport sector cleaner, said Shell's downstream director John Abbott in an interview with BT on the fringes of Shell's Make the Future exhibition in Changi.
