Deep dive: Satellite & remote sensing for climate — the hidden trade-offs and how to manage them

The satellite remote sensing market reached $48.6 billion in 2025, with earth observation for climate monitoring growing at 12-16% CAGR—outpacing nearly every other geospatial segment, according to Mordor Intelligence and SNS Insider market analyses. Yet behind these headline numbers lies a more complex reality: organizations deploying satellite-derived climate intelligence face fundamental trade-offs between resolution and coverage, between real-time alerting and cost efficiency, and between data richness and actionability. GHGSat's December 2024 publication in Science revealed that satellite constellations detected 8.3 million tons of methane emissions from 3,000+ oil, gas, and coal facilities in 2023 alone—emissions that had gone largely unreported through traditional ground-based monitoring. This breakthrough illustrates both the transformative potential and the persistent challenges: the technology works, but making it work for your specific use case requires navigating a thicket of hidden trade-offs.

Why It Matters

Climate commitments mean nothing without verification. The gap between reported emissions and actual atmospheric concentrations has become a central concern for regulators, investors, and corporate sustainability teams alike. The European Union's Carbon Border Adjustment Mechanism (CBAM), the SEC's proposed climate disclosure rules, and the International Sustainability Standards Board (ISSB) frameworks all depend on reliable emissions data—data that ground-based monitoring simply cannot provide at the scale and frequency required.

Satellite remote sensing addresses this gap by offering global coverage, consistent methodology, and independence from self-reported corporate data. A single satellite constellation can monitor millions of facilities across every jurisdiction simultaneously, providing the kind of systematic oversight that would require hundreds of thousands of ground inspectors to replicate.

The stakes are substantial. The World Bank estimates that accurate emissions monitoring could unlock $100 billion annually in carbon market transactions by providing the verification infrastructure that buyers demand. Insurance companies like Swiss Re and Munich Re now incorporate satellite-derived climate risk data into their underwriting models, affecting premiums for assets worth trillions of dollars. Asset managers representing over $130 trillion in assets under management have signed onto initiatives requiring portfolio-level climate disclosure—disclosure that increasingly depends on satellite-verified data.

For decision-makers, the question is no longer whether to use satellite climate data, but how to navigate the trade-offs inherent in different approaches. The wrong choices can lead to expensive data subscriptions that don't answer the questions that matter, or worse, to false confidence based on monitoring that misses critical emissions sources.

Key Concepts

Understanding satellite remote sensing for climate requires grasping several interconnected concepts that shape what's possible and what's practical.

Spatial Resolution vs. Coverage

Satellite sensors face a fundamental physics constraint: higher resolution means narrower swath width, which means fewer observations per orbit. GHGSat's constellation achieves 25-meter resolution—enough to pinpoint individual wellheads or pipes—but each satellite can only monitor targeted locations rather than providing continuous global coverage. By contrast, the Copernicus Sentinel-5P satellite covers nearly the entire Earth every 24 hours but at 7-kilometer resolution, suitable for regional-scale monitoring but unable to identify specific sources.

This trade-off has profound implications for use cases. Compliance monitoring of specific facilities requires high resolution and targeted revisit. Basin-level emissions accounting can use coarser resolution with broader coverage. Neither approach is superior; they serve different purposes.

Detection Limits and Intermittency

Current satellite technology detects methane emissions above approximately 100 kg/hour under ideal atmospheric conditions. This threshold excludes smaller persistent leaks that may collectively represent significant emissions. GHGSat's 2024 global analysis found that oil and gas facilities leak intermittently—only 16% of monitoring passes detected emissions at sites known to be emitters. Coal mines showed higher intermittency at 48% detection rates.

The intermittency challenge means that single-pass observations undercount total emissions. Accurate quantification requires repeated observations over time, statistical modeling of leak duration and frequency, and careful uncertainty quantification. Organizations using satellite data for emissions accounting must understand these limitations to avoid both under-reporting (missing intermittent events) and false precision (treating single observations as definitive).

Spectral Capabilities

Different satellite sensors detect different greenhouse gases and atmospheric conditions. Shortwave infrared (SWIR) sensors excel at methane and carbon dioxide detection. Thermal infrared sensors measure surface temperature and heat emissions. Hyperspectral imagers capture hundreds of narrow wavelength bands, enabling detection of multiple gas species and detailed surface characterization.

Carbon Mapper's Tanager-1 satellite, launched in August 2024 with NASA JPL's imaging spectrometer technology, represents the current frontier: hyperspectral sensing that can distinguish methane from carbon dioxide plumes and attribute emissions to specific sources with 50-meter accuracy. This capability enables new use cases—such as detecting CO₂ plumes from coal power plants—that previous methane-focused satellites could not address.

What's Working

Methane Super-Emitter Detection

The combination of GHGSat's commercial constellation and public initiatives like Carbon Mapper has created unprecedented visibility into the world's largest methane sources. GHGSat's 16-satellite constellation now provides daily monitoring capability for millions of facilities globally. Their December 2024 Science publication identified top-emitting countries—Turkmenistan, United States, Russia, Mexico, and Kazakhstan for oil and gas; China and Russia for coal—with facility-level specificity that enables targeted enforcement and remediation.

This capability has moved from proof-of-concept to operational deployment. ExxonMobil, Saudi Aramco, and other major operators now receive automated alerts within hours of detected emissions events, enabling rapid response that was previously impossible. The Environmental Defense Fund's MethaneSAT, launched in March 2024, adds complementary basin-scale monitoring that captures cumulative emissions across entire production regions.

Insurance and Financial Risk Assessment

Satellite-derived climate risk data has achieved mainstream adoption in insurance and real estate finance. ICEYE's synthetic aperture radar (SAR) satellites provide flood extent mapping regardless of cloud cover—a critical capability during extreme weather events when optical satellites are blocked. Their December 2024 Series E funding of $65 million, backed by BlackRock and Seraphim, reflects institutional confidence in this application.

Climate X, which raised $18 million in Series A funding led by Google Ventures in 2024, represents the analytics layer that translates raw satellite data into financial risk metrics. Their platform ingests satellite-derived hazard data and outputs property-level risk scores that banks and insurers use for portfolio management and underwriting decisions.

Deforestation Monitoring

Brazil's INPE agency and Global Forest Watch have demonstrated that satellite-based deforestation alerting works at scale. Near-real-time detection systems now identify forest clearing within days across the Amazon, Congo Basin, and Southeast Asian forests. This capability has enabled enforcement actions, commodity supply chain traceability, and carbon credit verification that depend on demonstrating forest preservation.

What's Not Working

Ground-Truthing at Scale

Satellite observations require ground-based validation to establish accuracy and calibrate detection algorithms. This ground-truthing remains expensive, logistically complex, and geographically sparse. A 2024 evaluation of GHGSat data published in the Journal of Geophysical Research found that satellite-derived emission rates correlated well with ground measurements (r² > 0.8) but showed systematic biases that varied by atmospheric conditions and geography.

For organizations building emissions inventories or carbon credit verification systems, this creates a persistent uncertainty that satellite data alone cannot resolve. The solution—deploying ground sensors or conducting aircraft campaigns—adds cost and complexity that undermines the scalability advantage satellites are supposed to provide.

Data Accessibility and Interoperability

Despite billions of dollars in satellite infrastructure, accessing and integrating climate data remains frustratingly difficult for most organizations. Different providers use different data formats, coordinate reference systems, and access mechanisms. The promise of "API-driven climate intelligence" often collides with the reality of bespoke data pipelines, manual data wrangling, and format conversion.

Commercial satellite data remains expensive for many applications. Planet Labs' high-resolution imagery costs thousands of dollars per square kilometer for historical archives. GHGSat's commercial monitoring services require enterprise-scale contracts. While initiatives like Carbon Mapper provide free public data, coverage and revisit rates remain limited compared to commercial alternatives.

False Positive Management

High-sensitivity satellite monitoring generates substantial false positive rates that create operational burden. A system tuned to detect 90% of real emissions events may also flag 10-20% of observations as potential events that turn out to be sensor noise, atmospheric interference, or benign sources. Managing this false positive load requires trained analysts, ground verification protocols, and organizational processes that many users lack.

The challenge intensifies with regulatory applications. A compliance system with a 15% false positive rate would overwhelm enforcement agencies and expose legitimate operators to unwarranted investigation. Achieving the precision required for regulatory use demands investment in algorithm refinement, ground-truthing campaigns, and quality assurance processes that current deployments often underestimate.

Key Players

Established Leaders

Planet Labs operates the world's largest commercial satellite constellation with over 200 satellites providing daily global coverage. Their partnership with Carbon Mapper on the Tanager-1 hyperspectral satellite extends their capability into greenhouse gas detection. Planet's archive of daily imagery dating back to 2016 enables temporal analysis that newer providers cannot match.

Maxar Technologies provides the highest-resolution commercial optical imagery available (30-centimeter resolution) through their WorldView Legion constellation. Their 2024-2025 launches expanded capacity for persistent monitoring of specific sites, though their climate applications focus more on infrastructure and land use change than atmospheric composition.

Airbus Defence and Space operates the Pléiades Neo constellation and provides data for the European Copernicus program. Their October 2024 partnership with ESA for next-generation climate monitoring satellites positions them as a long-term infrastructure provider for European climate data needs.

ICEYE has established market leadership in SAR-based flood and disaster monitoring with 25+ satellites providing day-night, all-weather imaging capability that optical systems cannot match.

Emerging Startups

Examples

GHGSat and Turkmenistan Emissions: GHGSat's 2024 global methane analysis identified Turkmenistan as the world's largest source of oil and gas methane emissions per unit of production. Satellite observations documented persistent venting from specific facilities that Turkmen authorities had not reported to international bodies. This transparency has enabled advocacy organizations and international agencies to focus diplomatic pressure and potential financing conditions on specific facilities with documented emissions, rather than relying on aggregate national statistics that governments can dispute.

Carbon Mapper Karachi Landfill Detection: In October 2024, Carbon Mapper's Tanager-1 satellite detected a 2.5-mile methane plume emanating from a Karachi landfill at 1,200 kg/hour—one of the largest point sources identified in South Asia. The public release of this detection, with precise coordinates and quantified emission rates, provided local authorities and development banks with actionable data for landfill gas capture project development. This case illustrates the potential for satellite transparency to unlock mitigation investments that self-reported inventories would never prioritize.

ICEYE Hurricane Response: During the 2024 Atlantic hurricane season, ICEYE's SAR constellation provided flood extent mapping within hours of storm passage—before clouds cleared enough for optical observation. Insurance companies used this data to accelerate claims processing, deploying adjusters to confirmed flood zones rather than waiting for ground reports. Lloyd's of London syndicates reported 40% faster initial loss estimates for events with ICEYE coverage compared to historical norms, demonstrating how satellite data can transform operational response times.

Action Checklist

• Define your primary use case: facility-level compliance monitoring requires different data products than regional emissions accounting or supply chain risk assessment
• Evaluate resolution-coverage trade-offs for your geographic scope: targeted monitoring of known facilities vs. discovery of unknown sources requires fundamentally different approaches
• Budget for ground-truthing and validation: plan for 15-25% of data costs to be allocated to verification activities that establish confidence in satellite-derived metrics
• Establish data pipeline infrastructure before procuring satellite feeds: most value destruction occurs in integration and analysis, not data acquisition
• Build organizational capacity for false positive management: define escalation protocols, analyst training, and ground verification workflows before production deployment
• Develop uncertainty communication frameworks: satellite-derived metrics require confidence intervals and caveats that traditional reporting may not accommodate
• Engage legal and compliance teams early: satellite data introduces novel evidentiary questions for disclosure, litigation, and regulatory proceedings

FAQ

Q: How accurate is satellite-based methane detection compared to ground measurements? A: Peer-reviewed validation studies show that satellite methane quantification achieves correlation coefficients (r²) above 0.8 with ground-based measurements under favorable conditions. However, systematic biases of 20-40% are common and vary by atmospheric conditions, viewing geometry, and surface properties. For compliance and disclosure purposes, satellite data should be treated as screening tools that identify sources for ground verification, not as standalone quantification systems. The 2024 McLinden evaluation of GHGSat data in the Journal of Geophysical Research provides the most rigorous independent assessment available.

Q: What are the typical costs for enterprise satellite climate data access? A: Costs vary dramatically by resolution, coverage, and use case. Basic global coverage from Copernicus/Sentinel is free but requires significant processing capacity. Commercial high-resolution imagery ranges from $15-50 per square kilometer for archive access to $200+ for tasked acquisitions. Methane monitoring services like GHGSat's SPECTRA platform operate on enterprise contracts typically starting at $100,000-500,000 annually for facility-level monitoring of dozens to hundreds of sites. The total cost of ownership—including data storage, processing, analysis, and ground validation—typically runs 2-3x the data acquisition cost.

Q: Can satellite data be used for regulatory compliance and legal proceedings? A: Regulatory acceptance is evolving rapidly. The EU's Methane Regulation, adopted in 2024, explicitly recognizes satellite-based monitoring as a compliance mechanism. The U.S. EPA has incorporated satellite data into enforcement proceedings, though legal precedent remains limited. For corporate disclosure, satellite-derived emissions estimates require careful uncertainty quantification and methodology documentation to withstand auditor scrutiny. Organizations should consult legal counsel on evidentiary standards in their jurisdictions and build documentation practices that anticipate regulatory and litigation use cases.

Q: How should I choose between commercial and public satellite data sources? A: Public sources (Copernicus, Landsat, NASA) provide excellent baseline capabilities at no data cost but require internal processing capacity and technical expertise. Commercial providers offer higher resolution, faster revisit, and often processed data products—at significant cost. Most sophisticated users combine both: public data for broad-area monitoring and historical analysis, commercial data for high-priority sites and near-real-time alerting. The decision framework should prioritize use case requirements (resolution, revisit, latency) over data source preference.

Q: What emerging capabilities should we monitor for 2025-2026? A: Three developments warrant attention. First, hyperspectral constellations (Carbon Mapper's planned Tanager expansion, European CHIME mission) will enable multi-species gas detection and more precise atmospheric characterization. Second, commercial thermal infrared satellites (Constellr, Hydrosat, OroraTech) will address water stress and heat applications that current optical and SAR systems underserve. Third, edge computing on satellites will enable on-orbit processing that reduces latency and data transmission costs, potentially transforming the economics of real-time alerting applications.
