The International Gas Union (IGU) has released a report for the G20 Energy Sustainability Working Group: Enabling Clean Marine Transport. Key Takeaways:
- While marine transportation is the most carbon-efficient mode of transport, in terms of CO2 emitted per unit of cargo, compared to road, air, or rail, the massive scale of shipping activities generates significant SO2, NOx, CO, black carbon, particulate matter, and CO2.
- Using LNG will reduce [these] harmful air pollutants significantly below all current and proposed emissions standards, [and] will immediately result in these reductions and persist for the life of the vessel.
- But… clear, consistent, and efficient [regulations are essential] for the deployment of […] marine LNG fuel transition […] since the marine sector is subject to a complex regulatory environment with overlapping jurisdictions that range from local to global. When lines between diverse regulatory bodies blur, it often leads to significant barriers for industry.
This situation is a key barrier facing LNG marine deployment globally and government must be encouraged to set clear regulatory guidelines that are essential in achieving broader and fleet-wide conversions.
