Global Challenges and Sustainable Prospects of the Maritime Industry

As shipping has the advantage of being the most cost-effective mode of transportation, it will continue to grow with increasing international trade flows. Therefore, this advantage must be leveraged to achieve the long-term goals of the maritime industry.

Identifying Emerging Challenges and Priorities for Aviation Decarbonization

Rubal Dua, Andres Felipe Guzman, Prateek Bansal

Decarbonization of the aviation sector has emerged as a global concern because the sector contributes 2%-3% to total global greenhouse gas emissions. Thus, it is critical for us to understand the associated emerging challenges. We determine key research priorities for…
