Navigating to Net Zero: Maritime Industry

⚓ Navigating to Net Zero: What It Means for the Maritime Industry

By Varuna Sentinels BV | ESG Compliance & Maritime Sustainability Solutions

As global climate commitments become legally binding, the maritime industry faces an inflection point. Regulatory frameworks are evolving, carbon intensity is under scrutiny, and stakeholders—from regulators to charterers—demand transparency, accountability, and measurable progress on ESG targets.

At Varuna Sentinels BV, we recognize that achieving net zero is not a checkbox exercise. It's a multi-stage operational transformation—one that demands clarity, innovation, and a solid compliance framework. Through our advanced ESG Platform, we empower ship owners, managers, and operators to confidently transition toward a sustainable, regulation-aligned future.

🌍 What Does "Net Zero Emissions" Mean?

Net Zero Emissions refers to achieving a balance where the total greenhouse gas (GHG) emissions released into the atmosphere are equal to the amount removed or offset, resulting in no net increase in atmospheric GHG levels. The goal is to reduce emissions as much as possible and then compensate for any remaining emissions by verified methods such as carbon capture, reforestation, or carbon offset projects.

Understanding Net Zero in the Maritime Industry

In the maritime sector, net zero emissions efforts must address emissions at multiple levels:

  • Scope 1 (Direct Emissions): These are emissions produced directly by ships, mainly from the combustion of marine fuels such as heavy fuel oil, marine diesel, or liquefied natural gas (LNG). This includes emissions from engines, boilers, and auxiliary machinery onboard vessels.
  • Scope 2 (Indirect Emissions): These emissions come from purchased electricity, steam, heating, or cooling consumed at shore-based facilities such as ports, offices, and shipyards. Even though these emissions occur off the ship, they are linked to the operational energy needs of maritime companies.
  • Scope 3 (Value Chain Emissions): These are upstream and downstream emissions related to the full lifecycle of maritime operations. Examples include the emissions generated during the production and transportation of marine fuels, ship maintenance activities, waste management, and ultimately, the recycling or dismantling of ships. Scope 3 typically represents the largest share of emissions and is often the hardest to measure and control.

⚠️ Key Clarification:
"Net Zero Carbon" covers only CO₂ emissions.
"Net Zero GHG" includes CO₂, methane (CH₄), nitrous oxide (N₂O), fluorinated gases, and others with high global warming potential.

🔍 Why Net Zero Matters Now

The international maritime community is under increasing regulatory and market pressure to align with climate goals:

Regulatory Landscape:

  • IMO GHG Strategy (Revised in 2023): Targets net zero GHG emissions by ~2050
  • MEPC 80 (2023) Resolution: Sets checkpoints for 2030, 2040, and 2050
  • EU Emissions Trading System (EU ETS): From 2024, shipping will be part of the carbon market
  • FuelEU Maritime Regulation: Enforces GHG intensity limits on marine fuels
  • CSRD & EU Taxonomy: Requires disclosure of environmental performance in financial and ESG reporting
  • EU Ship Recycling Regulation (EUSRR): Demands transparent end-of-life practices for EU-flagged vessels

Business Drivers:

  • Charterers and financiers now demand Science-Based Targets (SBTs)
  • ESG scores impact access to capital, insurance, and tenders
  • The rise of green shipping corridors and low-carbon fuel availability creates early-mover advantages

🚢 The Three-Stage Roadmap to Net Zero Shipping

At Varuna Sentinels BV, we help clients operationalize the transition through our Three-Stage Decarbonization Strategy:

ELIMINATE – Cut Avoidable Emissions

Examples:

  • Transition to low-carbon and alternative fuels (LNG, methanol, biofuels, ammonia)
  • Adopt energy-efficient technologies: air lubrication systems, energy-saving devices, optimized hull coatings
  • Retrofit with waste heat recovery, solar/wind-assist propulsion
  • Implement IHM-compliant material selection to avoid hazardous inputs

Our ESG Platform tracks fuel-switching potential, port electrification use, and onboard system upgrades, integrating this into your broader ESG and compliance strategy.

OPTIMIZE – Improve Operational Efficiency

Examples:

  • Voyage optimization and weather routing
  • Speed reduction and dynamic trim control
  • Shore power connection during berthing
  • Enhanced waste segregation and recycling
  • Predictive maintenance to reduce drydocking emissions

Our ESG Platform integrates real-time data inputs to track emissions per voyage, benchmark vessel efficiency (using CII, EEXI, EEDI), and calculate your GHG inventory by scope.

OFFSET – Neutralize the Unavoidable

Some emissions cannot be fully eliminated today. That's where strategic offsetting becomes important.

Key Actions:

  • Invest in high-integrity carbon credits aligned with Gold Standard or Verra
  • Support blue carbon projects (mangrove restoration, marine biodiversity conservation)
  • Align offsets with your double materiality assessment under CSRD
  • Maintain full documentation and traceability to avoid greenwashing

Our ESG Platform includes an Offset Validation Module that helps ensure offsets are transparently reported, traceable, and verifiable by third-party auditors.

💻 Features of Our Maritime ESG Platform

Tailored specifically for the maritime sector, our ESG Platform helps clients meet compliance and performance objectives across:

Sustainability Reporting & Assurance

  • CSRD-aligned report generation (in line with GRI, EFRAG)
  • EU Taxonomy eligibility and alignment checker
  • Multi-stakeholder ESG disclosure (investors, clients, regulators)

Material Tracking & IHM Maintenance

  • Digital mapping of all hazardous materials onboard
  • Flag-state, class, and EU compliance readiness (HKC 2009, MEPC 379(80), EUSRR)
  • Automated reminders and logbooks for maintenance

Real-Time Emissions Monitoring

  • Integrated tracking of fuel usage and emissions intensity
  • Scope 1, 2, 3 emissions dashboards
  • Compliance documentation for ETS, MRV, DCS, and FuelEU

Audit-Ready Data Repository

  • All ESG-related documents traceable in one place
  • Log-based changes for transparency during vetting, PSC, or third-party audits
  • Secure data access protocols for clients, partners, and authorities

⚡ Clean Fuel Transition: Challenges & Opportunities

While the industry looks to ammonia, hydrogen, and methanol as long-term solutions, practical challenges remain:

  • Safety and training for novel fuels
  • Limited bunkering infrastructure globally
  • Cost differentials vs. traditional HFO/MGO
  • Regulation gaps on alternative fuels in certain regions

We help clients assess fuel transition feasibility through:

  • Lifecycle Emissions Assessments (LCA)
  • Vessel-specific retrofitting studies
  • ESG risk/opportunity mapping for technology adoption
  • Integration of CAPEX/OPEX into decarbonization planning
