Beyond fuel: the case for a wider perspective on shipping and climate change

Climate Policy, Год журнала: 2025, Номер unknown, С. 1 - 9

Опубликована: Янв. 7, 2025

In July 2023, the International Maritime Organisation (IMO) set a new climate change strategy for international shipping sector. Critically, this now includes 'checkpoint' and 'strive' greenhouse gas emission reduction targets 2030 2040, en route to zero emissions by around 2050. Recent analysis highlights that IMO's are essential staging posts minimum level of ambition sector play its part in meeting Paris Climate goals. However, progress towards 2040 goals is being stymied an overly dominant narrative discourse focused on fuels longer-term (2050) targets: focus at odds with short-term targets, due long lead time deployment green scale, particularly given slow turn-over fleets. This article sets out why emphasis energy critical if Agreement. It no-regrets option, complementing necessary ongoing work alternative fuels. Recommendations realizing shift include aligning Carbon Intensity Indicator (CII) target, shifting organizational strategies reducing cumulative emissions, rethinking ship design optimize ultra-efficiency, wind-assist propulsion battery power.

Using a Just‐In‐Time Approach in the Green Supply Chain, Taking Into Account CO₂ Emissions, Under Uncertainty in the Pre‐ and Post‐COVID‐19 Situation

Discrete Dynamics in Nature and Society, Год журнала: 2025, Номер 2025(1)

Опубликована: Янв. 1, 2025

The main objective of this study is to develop a fuzzy‐based approach for building multistage, multiproduct, and multiperiod supply chain network (SCN) after before the COVID‐19 pandemic. proposed model optimizes production distribution planning under uncertainty in stochastic process network. designed help decision‐makers manage green (GSC) their organizations. It was developed using mixed‐integer linear programming (MILP) approach. aims maximize customer satisfaction pre‐ post‐COVID‐19 era by reducing total cost delivery time they face. also estimates production, asset locations, order allocation, inventory levels. Under uncertain conditions, new probabilistic MILP addresses SCN design (SCND) problem. two objectives are concepts ownership, activity‐based costing, just‐in‐time (JIT) production. model’s outputs include quantity goods purchased, produced, inventoried, delivered, transported selection suppliers COVID situation. A numerical example solved above technique given evaluate validate solution Finally, results presented.
