This summer, a stunning "luxury ship" named The Louis made waves not across the seas, but in the heart of Shanghai. Docked at the iconic Taikoo Hui on West Nanjing Road, The Louis quickly became a viral sensation — a bold blend of modern aesthetics and maritime culture. But while The Louis was turning heads in China's fashion capital, a much deeper transformation was taking place in the real world of ocean shipping: a global push toward zero-carbon maritime transport.

The Green Shipping Imperative

As climate change accelerates, the international shipping industry faces mounting pressure to decarbonize. In July 2023, the International Maritime Organization (IMO) adopted the IMO Strategy on Reduction of GHG Emissions from Ships (MEPC 80), establishing a long-term goal of achieving net-zero greenhouse gas emissions from international shipping by 2050. By 2030, the IMO calls for at least a 20% reduction in total GHG emissions from 2008 levels, with a stretch goal of 30%.

In parallel, the EU Emissions Trading System (EU ETS) officially expanded to include shipping from January 2024. This policy mandates full coverage of CO₂, CH₄, and N₂O emissions for intra-EU voyages, and 50% coverage for international voyages involving EU ports — increasing to 100% by 2026. By 2027, vessels over 5,000 GT (gross tonnage), which account for over 85% of global maritime emissions, will face mandatory compliance under IMO's upcoming net-zero framework. Non-compliance could result in penalties as high as USD 380 per ton of CO₂ emitted.

China's Role in the New Maritime Order

China is rapidly positioning itself as a global leader in green maritime innovation. In July 2025, Yangkpu Port in Hainan marked a national milestone: the country's first methanol-powered container vessel, built in China, fueled in China, and operating from a Chinese port — completing the nation's first "green shipping loop."

With over 400 dual-fuel methanol vessels on order globally, demand for low-carbon marine fuels like green methanol is expected to surge from 4.42 million tons to over 13 million tons by 2027.

SIGAS: Enabling the Future of Clean Shipping

As a global pioneer in gas analysis technologies, SIGAS is playing a critical role in empowering the shipping industry's net-zero transition. Backed by dual R&D hubs in Germany and China, SIGAS delivers cutting-edge sensing solutions for green ships, clean energy, and industrial decarbonization.

In 2025, SIGAS launched the MarineZero+ product platform — a scalable, cost-effective solution for carbon tracking, emission compliance, and fuel optimization across the maritime value chain.

MarineZero+ Solutions at a Glance

EmissionGuard CGC Series – Tailpipe Monitoring

SIGAS's EmissionGuard CGC Continuous Emissions Monitoring System (CEMS) provides real-time tracking of multiple pollutants including SO₂, NOx, CO₂, CH₄, and N₂O. Compatible with LNG, diesel, methanol, biofuels, and more, the system features patented NDIR + NDUV dual-spectrum technology and supports carbon accounting, regulatory reporting, and ESG audits.

EngineGuard – Engine Process Gas Monitoring System

In collaboration with top marine engine manufacturers, SIGAS developed EngineGuard, a high-precision gas detection system for dual-fuel engines (LNG, methanol, ammonia). Using advanced photoacoustic and laser spectroscopy, EngineGuard offers ppm-level detection of CH₄ and NH₃ leaks at fuel injection and bunkering points — safeguarding crews and ports during alternative fuel operations.

From Data to Decisions

What sets SIGAS apart is not just its hardware, but the intelligence behind it. By building a full-stack carbon management ecosystem — from fuel bunkering to tailpipe emissions — SIGAS enables a full lifecycle carbon footprint traceability. The MarineZero+ suite closes the loop with an integrated system of monitoring, analysis, and decision-making, giving shipowners and operators the tools they need to:

• Ensure full compliance with IMO and EU carbon regulations
• Optimize fuel consumption and reduce OPEX
• Monetize carbon assets through accurate, verified data

Whether you're a shipowner, OEM, port authority, or logistics provider, SIGAS invites you to join the journey — and sail confidently toward a cleaner, smarter maritime future.
