Assisting new technologies for greener shipping
Environmental concerns are influencing a greater need for renewable and sustainable energy across the world with specialist technologies being at the forefront of new designs and solutions. The environmental impact of shipping includes air pollution, water pollution, acoustic, and oil pollution. Commercial ships are responsible for more than 18 percent of some air pollutants, including greenhouse gas emissions.
Methane at Sea: Finding the Invisible Climate Killer
T&E’s investigation into so-called ‘green’ liquid natural gas (LNG) ships uncovers significant amounts of invisible methane being released into the atmosphere. On a crisp Monday morning in the port of Rotterdam, the Ecodelta, a dredger boat, gets to work scraping the seabed, clearing the way for…
Ammonia in Aquatic Systems
by Ruth Francis-Floyd, Craig Watson, Denise Petty, and Deborah B. Pouder Of all the water quality parameters that affect fish, ammonia is the most important after oxygen, especially in intensive systems, says Ruth Francis-Floyd, Craig Watson, Denise Petty, and Deborah B. Pouder, University of Florida…
Ammonia pollution damaging more than 60% of UK land – report
Study finds most sensitive plant and wildlife habitats are worst affected, yet government has no clear plans to monitor impact Ammonia and nitrogen pollution, mostly from farms, is harming more than 60% of the UK’s land area and hitting the most sensitive habitats for plants…
Ecological Effects of Ammonia
Even at extremely low concentrations aquatic life will be harmed by ammonia. Ammonia occurs naturally in the environment. A small amount of ammonia is generated when lightning strikes and reaches earth in rainfall. But most ammonia is produced by bacteria in water and soil as…
Study provides first statistical characterisation of methane ultra-emitters from oil and gas
For the first time ever on a global scale, using satellite imagery, scientists have quantified volumes of massive methane emissions due to fossil-fuel extraction activities and their impact on the climate. Their findings partly explain why official inventories generally underestimate the volume of these emissions….
For Many, Blue Hydrogen Is the Fuel of the Future. New Research Raises Doubts.
Industry has been promoting blue hydrogen as a reliable, next-generation fuel to power cars, heat homes and generate electricity. It may, in fact, be worse for the climate than previously thought. It is seen by many as the clean energy of the future. Billions of…
China Nav comes out in favour of Marshall Islands’ carbon tax proposal, readies first sail-assisted newbuild
China Navigation is to sign for a revolutionary sail-assisted newbuild this month as part of a package of green measures announced today. The Swire subsidiary has also come out in favour of the proposal put forward to the International Maritime Organization (IMO) by the Marshall…
$100 per tonne emissions levy put forward by the Marshall Islands and Solomon Islands
Upping the stakes ahead of this year’s crunch Marine Environment Protection Committee (MEPC) meeting at the International Maritime Organization (IMO), the Marshall Islands and the Solomon Islands have put forward a proposal to establish a universal, mandatory greenhouse gas (GHG) levy with an entry price…
