Green Shipping: The Future of Sustainable Maritime Industry

The maritime industry is undergoing a revolutionary transformation toward sustainability. With shipping responsible for nearly 3% of global greenhouse gas emissions, the push for green shipping has never been more urgent.

Why Green Shipping Matters

Environmental Impact:
- Shipping emits 940 million tons of CO₂ annually
- Marine pollution affects ocean ecosystems
- Air pollution impacts coastal communities

Regulatory Pressure:
- IMO 2030: 40% reduction in carbon intensity
- IMO 2050: Net-zero emissions target
- Regional regulations (EU ETS, Asia-Pacific initiatives)
