Abstract
This paper provides an overview of the effects between existing diesel engines and eco-friendly lean burn LNG (Liquefied Natural Gas) fuelled engines in economic and environmental aspects in application of harbour tug.

Climate change is now widely recognized as the major environmental problem facing the globe.

GHG (Greenhouse gas) emissions have grown markedly since pre-industrial time, especially emissions from the transport and energy sectors.

Without additional measures to mitigate climate change, GHG emissions will continue to grow in near future and beyond.

Legislations and regulations to reduce emissions had been tighten in globally, for instance October 2008 MARPOL amendments- revised Annex VI regulations to reduce harmful emissions from ships, this protocol including a progressive reduction in sulphur oxide (SOx) and nitrogen oxide (NOx) emissions from ships.

According to this research, application of LNG engines instead of existing diesel engines to harbour tugs in Busan can reduce fuel cost KRW 9.3 billion and reduce CO2 emission 6,576 tons annually based on MCR 75% rating.

Also above application can save fuel cost KRW 55.1 billion and cut CO2 emission up to 38,000 tons annually when apply the LNG engines to all 183 harbour tugs in the whole country.

To reduce GHG emissions have a certain cost. However, they also constitute an economic & environmental benefit, reducing air pollution and energy resource depletion.

Variety of policy tools can be applied by governments to create incentives for the popularization of LNG engines to harbour tugs or costal vessels and support establishing infrastructure of LNG supply in port, such as regulation, taxation and subsides.

LNG is set to become an important marine fuel of the future and LNG engines with related technology will contribute effectually toward green growth and green logistics.
