Decarbonizing Aviation and Shipping: The Role of Carbon Removal.

Reading Time: ~12 minutes
Key Takeaway: “Decarbonizing Aviation and Shipping: The Role of Carbon Removal.” shows how two of the hardest-to-clean sectors—air travel and sea freight—can bridge the gap to net-zero using carbon removal technologies alongside cleaner fuels and smarter operations.

Introduction

Problem: The aviation and shipping industries are major emitters of greenhouse gases—yet switching them off or entirely replacing fossil fuels overnight is virtually impossible.
Agitation: Without bold solutions, these sectors alone could consume a large portion of the remaining “carbon budget” and undermine climate targets.
Solution: Here’s Decarbonizing Aviation and Shipping: The Role of Carbon Removal. We’ll explore how carbon removal—capturing CO₂ from the air or emissions, storing it or turning it into useful products—can play a vital role when fuel switching and efficiency reach their limits.

Why Aviation and Shipping Need Carbon Removal

Let’s explain Decarbonizing Aviation and Shipping: The Role of Carbon Removal in simple terms.

What are we talking about?

Aviation currently accounts for about 2–3% of global CO₂ emissions and could grow if travel grows faster than decarbonisation efforts. RMI+2systemschangelab.org+2
Shipping also contributes about 3% of global greenhouse gases and faces challenges due to long vessel lifetimes and fuel types. systemschangelab.org+1
“Carbon removal” means taking CO₂ out of the atmosphere (or preventing emissions from being released) and storing it safely or turning it into something useful.

Why is removal needed?

Even with the best efforts—improved fuels, efficiency, electrification—some emissions will remain because of technical or economic limits. For aviation, sources say: “carbon dioxide removal (CDR) solutions are required to remove residual emissions from renewable fuels but cannot replace decarbonisation.” McKinsey & Company+1
For shipping and aviation to meet ambitious climate targets (e.g., aligning with the Paris Agreement), removal becomes a key part of the mix. MDPI+1
The sectors are “hard to abate.” Fuel alternatives exist but face high cost, infrastructure challenges, long asset lifetimes. MDPI+1

Simple analogy

Imagine you’re cleaning your house (the planet). You’ve swept the floor (fuel switching, efficiency) and wiped the surfaces (operational changes). But dust keeps settling in corners you can’t reach (residual emissions). Carbon removal is like vacuuming those corners and cleaning filters. If you only swept but didn’t vacuum, the dirt accumulates again.

Key Levers in Decarbonization for Aviation & Shipping

To appreciate Decarbonizing Aviation and Shipping: The Role of Carbon Removal, we need to look at other levers these sectors are already deploying—and where removal fits in.

Fuel switching & alternative fuels

Aviation: Sustainable aviation fuels (SAFs) made from waste or bio-resources show promise—potential to reduce carbon intensity by large margins. RMI+1
Shipping: Alternative fuels like ammonia, hydrogen or bio-methanol are under development, though uptake is slow. MDPI+1
These fuel changes are essential—but they cannot cover all activity soon enough.

Efficiency & operational changes

New aircraft or ships, optimized routing, speed reduction, improved load factors—all help reduce emissions. systemschangelab.org+1
Yet, these gains flatten out eventually and cannot push emissions to zero by themselves.

Demand management & mode shift

For shipping: rerouting, consolidation of loads, fewer empty voyages. For aviation: reducing non-essential travel, shifting to rail for short-haul flights. systemschangelab.org
These measures help, but global trade and travel demand continue to grow, increasing the challenge.

Enter carbon removal

This is where Decarbonizing Aviation and Shipping: The Role of Carbon Removal becomes relevant. Carbon removal helps to deal with the residual emissions that other measures cannot fully eliminate.

Carbon Removal: What It Means & How It Works

What exactly do we mean when we say “carbon removal” in the context of aviation and shipping? Let’s break it down.

Types of carbon removal

Direct Air Capture (DAC): Pulling CO₂ directly from ambient air, then storing it underground or using it in products.
Bioenergy with Carbon Capture and Storage (BECCS): Using biomass for energy, capturing the CO₂, storing it.
Ocean / mineral-based removal: Using natural processes or enhanced weathering to trap CO₂ in stable minerals or geological formations.
Carbon utilisation: Converting captured CO₂ into fuels or materials (though this may just delay emission rather than permanently remove it).

Why it matters for aviation & shipping

Aviation’s residual emissions (even with SAFs and efficiency) are hard to avoid. Reports note this specifically. McKinsey & Company+1
Shipping’s long asset lifetimes and slow fuel transition mean certain emissions will persist for decades. Removal provides a backstop. MDPI+1
Carbon removal gives these sectors negatives emissions capacity—meaning they can go beyond “zero” to actually remove historic or residual emissions.

Challenges of carbon removal

Cost: Removal technologies are still expensive. McKinsey & Company
Scale: We’d need gigatons of CO₂ removed annually for meaningful impact—still a long way off.
Verification & permanence: Ensuring captured carbon actually stays stored or used in a durable way.
Infrastructure & energy: Many removal methods require large energy inputs or dedicated infrastructure.

How Carbon Removal Integrates with Aviation & Shipping Strategies

Here’s how the role of carbon removal fits into broader decarbonisation strategies in these sectors.

Step 1: Minimise emissions first

Use lowest carbon fuels possible (SAFs, hydrogen, low-sulphur fuels).
Improve efficiency of vehicles / vessels.
Reduce demand or shift mode where possible.
This reduces the size of “residual” emissions that removal must cover.

Step 2: Deploy removal to cover residuals

Estimate residual emissions after switching and efficiency.
Match removal capacity accordingly (tons of CO₂ to remove).
Integrate removal contracts into fuel supply chains, logistics planning.
For example: an airline might buy DAC credits to offset emissions it cannot avoid.

Step 3: Monitor, adjust and scale

Track fuel use, emissions, removal volumes.
Ensure removal is verified, permanent, and counted once only.
As removal cost drops and infrastructure improves, integrate more deeply into operations.
Removal becomes part of fuel & emission accounting rather than “just offsets”.

Step 4: Communicate and report

For stakeholders (investors, regulators, customers), show how removal fits into your overall pathway.
Transparency builds credibility: “We used X kg of SAF, improved efficiency by Y%, removed Z kg of CO₂.”
This helps align with net-zero commitments and emerging aviation/shipping sector standards.

Case Highlights & Emerging Examples

Let’s look at real-world signals for Decarbonizing Aviation and Shipping: The Role of Carbon Removal.

One article: “Why Carbon Removal is Critical to Reaching Net-Zero Aviation” — noting that even with SAFs and hydrogen, removal is required. Sustainability Magazine
A modeling study on shipping & aviation found that deep decarbonization scenarios rely heavily on low-carbon fuels and systemic change, and implicitly removal for residuals. MDPI+1
A political / policy brief: shipping industry may see emissions increase unless low-carbon fuels and removal escalate. Carbon Market Watch

These examples show that the role of carbon removal is gaining recognition—but the scale and pace still need acceleration.

What Companies & Organisations Should Do

If you are in aviation, shipping, fuel supply, logistics or policy, here are practical steps to participate in Decarbonizing Aviation and Shipping: The Role of Carbon Removal.

For Airlines & Shipping Operators

Conduct an emissions inventory: how much CO₂ (and other GHGs) do you emit, now and projected?
Estimate how much of those emissions you can eliminate via fuel switching, efficiency.
Identify your “residual emissions” – what removal you will need.
Engage with removal providers: DAC firms, BECCS projects, certified removal credits.
Incorporate removal contracts into your procurement of fuels, logistics, carbon budgeting.
Monitor removal performance, ensure transparency, audit credits.
Communicate to customers and stakeholders: your pathway includes both reduction and removal.

For Fuel Suppliers & Technology Providers

Invest in production and supply of SAFs, hydrogen, low-carbon fuels—but also in removal technologies.
Forge partnerships: removal tech + fuel production + logistics.
Provide life-cycle assessments: how much CO₂ removed or avoided per liter of fuel delivered.
Help clients in aviation/shipping quantify how your product helps them on their net-zero pathway.

For Regulators & Policymakers

Create frameworks that recognise and reward removal in aviation/shipping sectors.
Support incentives or mandates for removal alongside low-carbon fuel production.
Ensure removal credits are robust: if aviation/shipping claim to use removal, it must be verified, permanent, additional.
Address infrastructure requirements: ports, airports, bunkering of low-carbon fuels, removal storage sites.
Foster global cooperation—these industries are international, removing CO₂ requires global standards.

Barriers & How to Overcome Them

Understanding Decarbonizing Aviation and Shipping: The Role of Carbon Removal also means knowing what blocks progress—and how to remove those blocks.

Barrier: High cost & uncertain business model

Solution: Scale-up removal tech to reduce cost; bundle removal contracts into fuel supply to share cost.
Solution: Government subsidies, carbon pricing to level the playing field.

Barrier: Infrastructure and technology lag

Solution: Early investment in ports/airports, bunkering of low-carbon fuels, removal storage facilities.
Solution: Collaborate across sectors (fuel, infrastructure, logistics, finance).

Barrier: Lack of regulatory recognition for removal in these sectors

Solution: Encourage aviation and maritime regulatory bodies (like International Civil Aviation Organization – ICAO, International Maritime Organization – IMO) to integrate removal into frameworks.
Example: ICAO’s CORSIA is offset-based; consider how removal fits in. Wikipedia

Barrier: Credibility of removal claims

Solution: Use certified removal credits, auditable chains of custody, transparency in volumes removed, permanence confirmed.
Solution: Combine removal with reduction measures—don’t rely on removal alone.

Barrier: Competing demands for low-carbon fuels and removal across sectors

Solution: Prioritise hardest-to-abate sectors (aviation, shipping) for removal and low-carbon fuels.
Solution: Cross-sector collaboration to allocate biomass, hydrogen, electricity efficiently. MDPI
