風力推進システムを搭載した貨物船において、有利な風を最大限に利用するよう航路や速度を調整すれば、エネルギー消費量を50%から100%削減できる可能性があると研究者らが発表しました。
海運業界は世界の二酸化炭素排出量の約3%を占めており、その割合は現在も上昇を続けています。硬翼帆、回転式帆（ローター）、巨大なカイト（凧）などの技術導入は、燃料コストの削減を目指す企業からすでに注目を集めています。新たな研究によると、現実的な配送時間を維持しつつ、風の力を最大限に活用するように船舶が航路や速度を変更すれば、さらなる大きな効果が見込めると示されています。
The Trump administration has threatened countries supporting a proposed carbon tax on global shipping with visa restrictions, tariffs, and port fees. Despite this pressure, a slim majority of nations backed the original Net-Zero Framework at a recent U.N. meeting.

China launched its first zero-carbon river-sea shipping route Tuesday as the all-electric container vessel Ningyuan Dianpeng departed Jiaxing Port on its maiden voyage to Ningbo Zhoushan Port.
Emissions of carbon monoxide and volatile organic compounds have contributed significantly to planetary warming, according to new research. These indirect greenhouse gases account for about 15 percent of the temperature rise since pre-industrial times. Few nations currently address them in climate plans.

Growing seaweed to capture carbon dioxide could deplete ocean nutrients and reduce the effectiveness of natural carbon sinks, according to new research. The approach risks increasing atmospheric CO2 in some scenarios rather than lowering it. Two studies highlight significant ecological trade-offs.
A new report from the Ellen MacArthur Foundation urges policymakers to integrate bio-based materials into circular economy strategies. The analysis finds that renewable materials such as cotton, wood, and rubber have largely been overlooked, missing opportunities worth trillions of dollars and significant climate benefits.
