ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.

Emory, ICCT: ship emissions caused ~3,700 premature deaths in Pearl River Delta region in 2015

Green Car Congress

In 2015, ship emissions increased summer PM 2.5 The team also projected ship emissions in 2030 with and without an ECA, using two possible land scenarios. Assuming constant land emissions from 2015 in 2030 (2030 Constant scenario), they found that an ECA could avoid 811 PM 2.5 g/m 3 and 1.9

US MARAD study finds marine use of natural gas substantially reduces some air pollutants and slightly reduces GHG emissions

Green Car Congress

A recently released total fuel cycle analysis for maritime case studies shows that natural gas fuels reduce some air quality pollutants substantially, and reduce major greenhouse gas (GHG) emissions slightly, when compared to conventional petroleum-based marine fuels (low-sulfur and high-sulfur).
