Kapal kargo berbantuan angin dapat memangkas emisi hingga setengahnya melalui rute optimal

Para peneliti mengatakan bahwa kapal kargo yang dilengkapi dengan sistem propulsi angin dapat mengurangi penggunaan energi mereka sebesar 50 hingga 100 persen jika mereka menyesuaikan rute dan kecepatan untuk memanfaatkan angin yang menguntungkan secara maksimal.

Sektor pelayaran menyumbang sekitar 3 persen emisi karbon dioksida global, porsi yang terus meningkat. Menambahkan teknologi seperti layar kaku, silinder berputar, dan layang-layang raksasa telah menarik minat perusahaan yang mencari biaya bahan bakar lebih rendah. Sebuah studi baru menunjukkan bahwa hasil yang lebih besar mungkin dicapai ketika kapal juga memvariasikan jalur dan kecepatan mereka untuk memaksimalkan bantuan angin sembari tetap berada dalam waktu pengiriman yang realistis.

While renewable energy targets about 55% of greenhouse gas emissions, the circular economy tackles the remaining 45% from material production and use. This approach replaces the linear take-make-waste model with strategies to design out waste, extend product life, and restore natural systems. Reports suggest it could reduce emissions by billions of tons annually across key sectors.

A massive LNG export terminal under construction near Lake Charles, Louisiana, is projected to produce more greenhouse gas emissions than any other in the United States. Owned by Woodside Energy, the facility is expected to release over 9.5 million tons annually once operational in 2029. The project has drawn praise for jobs and investment but criticism for worsening climate risks in a vulnerable state.
