Heathrow Airport is raising its climate ambition once again. In 2026, the airport plans to use Sustainable Aviation Fuel (SAF) at levels 2% higher than the UK government’s mandate. This means total SAF use at Heathrow could reach 5.6% of all jet fuel next year.
The UK requires 3.6% SAF blending in 2026. Heathrow’s extra incentive pushes that figure higher, which could translate into around 350,000 tonnes of SAF being used at the airport. About 124,000 tonnes of that would come directly from Heathrow’s own incentive scheme.
To support this effort, Heathrow has set aside more than £80 million to help airlines cover the higher cost of SAF compared to traditional jet fuel. SAF remains more expensive to produce, so this financial support helps narrow the price gap and makes cleaner fuel more attractive for carriers.
This is the fifth year in a row that Heathrow has expanded its SAF support program, showing a consistent push toward lower-carbon flying.
How SAF Cuts Aviation Emissions
Sustainable Aviation Fuel works in today’s aircraft without major changes. Airlines can blend it with regular jet fuel and use existing engines and infrastructure. The key difference lies in how SAF is produced.
It can be made from waste oils, agricultural residues, household waste, or through synthetic processes that combine renewable electricity with captured carbon. Because of these production methods, SAF can reduce lifecycle greenhouse gas emissions by more than 70% compared to fossil jet fuel, according to the UK government.
If Heathrow achieves its 5.6% SAF target in 2026, the airport estimates emissions could fall by around 600,000 tonnes in one year.
To understand the scale:
- A round-trip economy flight from London Heathrow to New York JFK produces about 612 kilograms of CO₂ per passenger, based on ICAO calculations.
- Cutting 600,000 tonnes would equal roughly 950,000 return passenger journeys on that route.
That level of reduction highlights how even small percentage increases in SAF use can create large carbon savings.
Understanding the UK SAF Mandate
The UK introduced the SAF Mandate to ensure steady growth in cleaner aviation fuel. Instead of relying only on voluntary airline commitments, the policy legally requires fuel suppliers to blend increasing amounts of SAF into their total jet fuel supply.
The system includes two parts. The main obligation requires suppliers to meet a rising SAF percentage each year.
- It started at 2% in 2025 and will increase to 10% by 2030 and 22% by 2040. A second requirement, known as the Power-to-Liquid obligation, focuses on advanced synthetic fuels made using renewable electricity. This part begins at 0.2% in 2028 and grows to 3.5% by 2040.
Suppliers earn certificates based on how much carbon savings their SAF delivers. The greater the emissions reduction, the more certificates they receive. They can use these certificates to prove compliance, trade them with others, or pay a buy-out fee if they fail to meet targets. The buy-out price is designed to encourage real SAF supply rather than paying the penalty.
- By 2040, the UK government estimates the mandate could deliver up to 6.3 megatonnes of carbon savings each year.
Matt Gorman, Heathrow’s Director of Sustainability, said,
“Sustainable Aviation Fuel is not a hypothetical concept for the future, it’s already producing real impact in 2026. Heathrow is leading the way globally, with 17% of the world’s SAF supply in 2024 used at the airport. SAF is a key lever on aviation’s journey to net zero by 2050, and a key element of Heathrow’s Net Zero Plan. Our incentive delivers real progress today, as well as a future promise for tomorrow.”

Heathrow’s SAF expansion fits into a larger strategy to reach net-zero emissions. As one of the world’s busiest international hubs, the airport is working to cut carbon both in flight operations and in ground activities.
By 2030, Heathrow aims to reduce flight-related emissions by up to 15% compared to 2019 levels. Achieving this depends heavily on scaling up SAF use and improving aircraft efficiency.
Looking further ahead, the airport targets at least an 80% reduction in emissions by 2050. The remaining emissions would need to be removed from the atmosphere to achieve full net zero.

Heathrow’s main roadmap assumes three key developments: continued improvements in aircraft efficiency, introduction of zero-carbon aircraft from the mid-2030s, and large-scale replacement of fossil jet fuel with SAF. In its lead scenario, SAF could replace up to 90% of remaining kerosene by 2050, delivering major lifecycle carbon savings.
There is also a more ambitious scenario in which fully synthetic fuels with near-zero lifecycle emissions replace all fossil-based jet fuel by mid-century.
Use of Hydrogen and Drop-in SAF
Hydrogen-powered aircraft could also play a role in aviation’s future. These planes may use hydrogen in fuel cells or burn it directly in turbines. However, experts expect hydrogen aircraft to serve mainly short-haul routes by 2050.
Shorter flights represent about 30% of global aviation emissions. Long-haul flights, which account for roughly 70%, will likely continue to depend on liquid fuels for decades. For those routes, drop-in SAF remains the most practical and scalable solution.
Heathrow says it must prepare its infrastructure to support hydrogen aircraft while keeping a strong focus on expanding SAF use for conventional planes.

Global SAF Market Reaches a Turning Point
The year 2025 marks a major shift for the global SAF market. Blending mandates in both the European Union and the UK have begun to drive demand growth. SAF demand in the EU could reach about 0.9 million tonnes in 2025, while the UK could require around 0.25 million tonnes. Globally, total demand may approach 2 million tonnes this year.
Industry report says, by 2030, global SAF demand could climb to 15.5 million tonnes. Around 4.4 million tonnes of that would come from existing mandates, while the rest would depend on new policies, incentives, and voluntary airline commitments. Nearly 60 airlines have pledged to use 10% SAF by 2030, creating additional market momentum.
However, supply remains fragile. Announced global SAF production capacity for 2030 stands at about 18 million tonnes. While this appears enough on paper, delays and project cancellations in Europe, the UK, and the United States have raised concerns. Lower fossil fuel prices, policy uncertainty, and broader economic pressures have slowed some investments.
Beyond 2030, the challenge grows even larger. By 2035, global SAF demand could reach 40 million tonnes. Meeting that level will require rapid expansion of production capacity over a short period.

A Strong Signal to the Aviation Industry
Heathrow’s decision to exceed the national SAF mandate sends a clear message. Airports can influence the pace of decarbonization, not just governments and airlines.
By offering financial incentives and committing to higher SAF uptake, Heathrow strengthens confidence in the long-term growth of sustainable aviation fuel. Whether supply can scale fast enough remains the key question. For now, the airport’s 5.6% SAF target for 2026 marks a bold and practical step toward cleaner aviation.

Carbon credit project stewardship: what happens after credit issuance
A carbon credit purchase is not a transaction that closes at issuance. The credit may be retired, the certificate filed, and the reporting box ticked. But on the ground, in the forest, in the field, and in the community, the work continues. It endures for years. In many cases, for decades.

Industries with the biggest nature footprints and what their decarbonisation looks like
A corporate carbon footprint is never just an accounting figure. It maps onto real ecosystems. Before a product leaves the factory gate, something on the ground has already paid the cost. A forest has been converted. A river has been depleted. A patch of savannah that was once home to dozens of species now grows a single crop in every direction.

Apple, Amazon Lead 60+ Firms to Ease Global Carbon Reporting Rules
More than 60 global companies, including Apple, Amazon, BYD, Salesforce, Mars, and Schneider Electric, are pushing back against proposed changes to global emissions reporting rules. The group is calling for more flexibility under the Greenhouse Gas Protocol (GHG Protocol), the most widely used framework for measuring corporate carbon footprints.
The companies submitted a joint statement asking that new requirements, especially those affecting Scope 2 emissions, remain optional rather than mandatory. Their letter stated:
“To drive critical climate progress, it’s imperative that we get this revision right. We strongly urge the GHGP to improve upon the existing guidance, but not stymie critical electricity decarbonization investments by mandating a change that fundamentally threatens participation in this voluntary market, which acts as the linchpin in decarbonization across nearly all sectors of the economy. The revised guidance must encourage more clean energy procurement and enable more impactful corporate action, not unintentionally discourage it.”
The debate comes at a critical time. Corporate climate disclosures now influence trillions of dollars in capital flows, while stricter reporting rules are being introduced across major economies.
The Rulebook for Carbon: What the GHG Protocol Is and Why It’s Being Updated
The Greenhouse Gas Protocol is the world’s most widely used system for measuring corporate emissions. It is used by over 90% of companies that report greenhouse gas data globally, making it the foundation of most climate disclosures.
It divides emissions into three categories:
- Scope 1: Direct emissions from operations
- Scope 2: Emissions from purchased electricity
- Scope 3: Emissions across the value chain

The current Scope 2 rules were introduced in 2015, but energy markets have changed since then. Renewable energy has expanded, and companies now play a major role in funding clean power.
Corporate buyers have already supported more than 100 gigawatts (GW) of renewable energy capacity globally through voluntary purchases. This shows how influential the current system has been.
The GHG Protocol is now updating its rules to improve accuracy and transparency. The revision process includes input from more than 45 experts across industry, government, and academia, reflecting its global importance.
Scope 2 Shake-Up: The Battle Over Real-Time Carbon Tracking
The proposed update would shift how companies report electricity emissions. Instead of using flexible systems like renewable energy certificates (RECs), companies would need to match their electricity use with clean energy that is:
- Generated at the same time, and
- Located in the same grid region.
This is known as “24/7” or hourly or real-time matching. It aims to reflect the actual impact of electricity use on the grid. Companies, including Apple and Amazon, say this shift could create challenges.

According to industry feedback, stricter rules could raise energy costs and limit access to renewable energy in some regions. It can also slow corporate investment in new clean energy projects.
The concern is that many markets do not yet have enough renewable supply for real-time matching. Infrastructure for tracking hourly emissions is also still developing.
This creates a key tension. The new rules could improve accuracy and reduce greenwashing. But they may also make it harder for companies to scale clean energy quickly.
The outcome will shape how companies measure emissions, invest in renewables, and meet net-zero targets in the years ahead.
Why More Than 60 Companies Oppose the Changes
The companies argue that stricter rules could slow climate progress rather than accelerate it. Their main concern is cost and feasibility. Many regions still lack enough renewable energy to support real-time matching. For global companies, aligning energy use across different grids is complex.
In their joint statement, the group warned that mandatory changes could:
- Increase electricity prices,
- Reduce participation in voluntary clean energy markets, and
- Slow investment in renewable energy projects.
They argue that current market-based systems, such as RECs, have helped scale clean energy quickly over the past decade. Removing flexibility could weaken that momentum.
This reflects a broader tension between accuracy and scalability in climate reporting.
Big Tech Pushback: Apple and Amazon’s Climate Progress
Despite their push for flexibility, both companies have made measurable progress on emissions reduction.
Apple reports that it has reduced its total greenhouse gas emissions by more than 60% compared to 2015 levels, even as revenue grew significantly. The company is targeting carbon neutrality across its entire value chain by 2030. It also reported that supplier renewable energy use helped avoid over 26 million metric tons of CO₂ emissions in 2025 alone.

In addition, about 30% of materials used in Apple products in 2025 were recycled, showing a shift toward circular manufacturing.
Amazon has also set a net-zero target for 2040 under its Climate Pledge. The company is one of the world’s largest corporate buyers of renewable energy and continues to invest heavily in clean power, logistics electrification, and low-carbon infrastructure.

Both companies argue that flexible accounting frameworks have supported these investments at scale.
The Bigger Challenge: Scope 3 and Digital Emissions
The debate over Scope 2 reporting is only part of a larger issue. For most large companies, Scope 3 emissions account for more than 70% of total emissions. These include supply chains, product use, and outsourced services.
In the technology sector, emissions are rising due to:
- Data centers,
- Cloud computing, and
- Artificial intelligence workloads.
Global data centers already consume about 415–460 terawatt-hours (TWh) of electricity per year, equal to roughly 1.5%–2% of global power demand. This figure is expected to increase sharply. The International Energy Agency estimates that data center electricity demand could double by 2030, driven largely by AI.
This creates a major reporting challenge. Even with cleaner electricity, total emissions can rise as digital demand grows.
Climate Reporting Rules Are Tightening Globally
The pushback comes as climate disclosure requirements are expanding and becoming more standardized across major economies. What was once voluntary ESG reporting is steadily shifting toward mandatory, audit-ready climate transparency.
In the European Union, the Corporate Sustainability Reporting Directive (CSRD) is now active. It requires large companies and, later, listed SMEs, to share detailed sustainability data. This data must match the European Sustainability Reporting Standards (ESRS). This includes granular reporting on emissions across Scope 1, 2, and increasingly Scope 3 value chains.
In the United States, the Securities and Exchange Commission (SEC) aims for mandatory climate-related disclosures for public companies. This includes governance, risk exposure, and emissions reporting. However, some parts of the rule face legal and political scrutiny.
The United Kingdom has included climate disclosure through TCFD requirements. Now, it is moving toward ISSB-based global standards to make comparisons easier. Similarly, Canada is progressing with ISSB-aligned mandatory reporting frameworks for large public issuers.
In Asia, momentum is also accelerating. Japan is introducing the Sustainability Standards Board of Japan (SSBJ) rules that match ISSB standards. Meanwhile, China is tightening ESG disclosure rules for listed companies through updates from its securities regulators. Singapore has also mandated climate reporting for listed companies, with phased Scope 3 expansion.
A clear trend is forming across jurisdictions: climate disclosure is aligning with ISSB global standards. There’s a growing focus on assurance, comparability, and transparency in value-chain emissions.
This regulatory tightening raises the bar significantly for corporations. The challenge is clear. Companies must:
- Align with multiple evolving disclosure regimes,
- Ensure emissions data is verifiable and auditable, and
- Expand reporting across complex global supply chains.
Balancing operational growth with compliance is becoming increasingly complex as climate regulation converges and intensifies worldwide.
A Turning Point for Global Carbon Accounting
The outcome of this debate could shape global carbon accounting standards for years.
If stricter rules are adopted, emissions reporting will become more precise. This could improve transparency and reduce greenwashing risks. However, it may also increase compliance costs and limit flexibility.
If the proposed changes remain optional, companies may continue using current accounting methods. This could support faster clean energy investment, but may leave gaps in reporting accuracy.
The new rules could take effect as early as next year, making this a near-term decision for global companies.
The push by Apple, Amazon, and other companies highlights a key tension in climate strategy. On one side is the need for accurate, real-time emissions reporting. On the other is the need for flexible systems that support large-scale clean energy investment.
As digital infrastructure expands and energy demand rises, how emissions are measured will matter as much as how they are reduced. The next phase of climate action will depend not just on targets—but on the systems used to track them.
