Seaspan says it will measure the carbon dioxide emissions from 109 containerships with the help of DNV technology.

The move comes as CO2 becomes the next target for environmental regulations in the shipping industry. The measurements from Seaspan will become part of a broader set of data that will form a benchmark for future legislation on CO2 emissions.

The European Union will require shipowners to monitor the CO2 emissions from vessels calling on European ports beginning next year, with emissions data published annually.
