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.

Study: IMO low-sulfur fuel standards will decrease childhood asthma cases, premature deaths; climate tradeoffs

Green Car Congress

Some key regions include China, Singapore, Panama, Brazil and coastlines of Asia, Africa and South America. While the health benefits are clear, the research also quantifies tradeoffs in terms of climate. Reduction in annual PM 2.5 concentrations in 2020 due to low-sulfur fuel standards. —Sofiev et al.

Maersk sets net zero CO2 emission target by 2050

Green Car Congress

In comparison, a container vessel carrying thousands of TEU sailing from Panama to Rotterdam makes around 8,800 km. We will invest significant resources for innovation and fleet technology to improve the technical and financial viability of decarbonized solutions. The next 5-10 years are going to be crucial.

ICCT study examines current & projected use of heavy fuel oil in Arctic shipping; growth in BC emissions points to need for policies

Green Car Congress

A new study by the International Council on Clean Transportation (ICCT) estimates heavy fuel oil (HFO) use, HFO carriage, the use and carriage of other fuels, black carbon (BC) emissions, and emissions of other air and climate pollutants for the year 2015, with projections to 2020 and 2025. —Comer et al.

ICCT study finds GHGs from shipping on the rise

Green Car Congress

Ships registered to Panama (15%), China (11%), Liberia (9%), Marshall Islands (7%), Singapore (6%), and Malta (5%) were the largest emitters. The study also identifies black carbon as the second most important climate pollutant after CO 2 , representing between 7% to 21% of the total climate impact of shipping. Click to enlarge.

Study finds enhanced tropical forest growth could result in carbon release from soil; priming stimulates decomposition

Green Car Congress

A new study led by scientists from the Centre for Ecology & Hydrology and the University of Cambridge, UK shows that as climate change enhances tree growth in tropical forests, the resulting increase in litterfall could stimulate soil micro-organisms, leading to a release of stored soil carbon.

DOE selects 2 projects to demonstrate feasibility of enhanced water recovery; producing usable water from CO2 storage sites

Green Car Congress

The field projects will also help to find cost effective ways to treat extracted brines in order to generate a usable water supply and support DOE’s objectives to improve water management and conservation for power generation, hydrocarbon production, and industrial processes; particularly in regions where water resources are scarce.
