LNG shipowner GasLog has released its first environmental, social and corporate governance (ESG) reports which show its 14 and 15-year-old steam turbine LNG carriers emit significantly more carbon dioxide than its modern gas-injection newbuildings.

The 24-page sustainability reports for both New York-listed GasLog and spin-off GasLog Partners, entitled “Sustainable Performance” include a breakdown of the grams of CO2 per ton-nautical mile emitted by each ship during 2019.
