Carbon Monitoring, Reporting, and Verification (MRV) serves as the backbone of any comprehensive strategy to combat climate change. It provides the necessary data to understand the scale of emissions and removals of greenhouse gases. While traditional methods of MRV rely heavily on ground-based surveys and direct measurements, they often come with limitations such as high costs, limited coverage, and the potential for human error. The emergence of space technology as a viable tool for environmental monitoring offers new possibilities for enhancing MRV systems. This article explores the role of satellite imagery and remote sensing in carbon MRV, discussing its applications, benefits, challenges, and the companies involved in offering these advanced services.
Satellite Imagery
Land Use and Deforestation
Satellite imagery has been instrumental in revolutionizing the way we monitor land use changes, particularly deforestation and afforestation. High-resolution satellites can cover vast swaths of land, capturing minute details that can be used to detect changes in vegetation cover. By using time-series analysis of these images, it becomes possible to track how specific areas are being affected by human activities or natural events, thereby giving a clearer picture of carbon emissions resulting from land use changes.
Ocean Monitoring
The world’s oceans are significant carbon sinks, and understanding their role in carbon cycling is vital. Specialized satellites equipped with ocean-color sensors can detect levels of chlorophyll, which is indicative of phytoplankton presence. These microscopic plants absorb carbon dioxide during photosynthesis, making them an essential component in the planet’s carbon cycle. Monitoring their levels through satellite imagery helps estimate the ocean’s capacity to absorb carbon, thus enriching our MRV capabilities.
Remote Sensing
Spectroscopy for Emission Detection
Remote sensing technologies have advanced to the point where they can identify specific gases in the Earth’s atmosphere through spectroscopy. By examining the light spectrum, it’s possible to determine the presence and concentration of gases like carbon dioxide and methane. This serves as an important supplement to ground-based sensors, enabling a more comprehensive understanding of emissions on a global scale.
Soil Carbon Stock
Soil acts as another important carbon sink. Advanced remote sensing technologies can penetrate the soil surface to measure organic carbon stocks. This not only helps in assessing the current status but also aids in monitoring the impact of land management practices aimed at improving soil health and increasing its carbon storage capabilities.
Data Integration and Analysis
Geographic Information Systems (GIS)
Geographic Information Systems (GIS) serve as a unifying platform that can integrate disparate data sources into a coherent whole. Satellite and remote sensing data can be overlaid with other forms of data, such as weather patterns and industrial activity reports, to provide a multifaceted view of carbon emissions and absorption.
Machine Learning Algorithms
With the sheer volume of data that satellite and remote sensing technologies can generate, machine learning algorithms become invaluable for sifting through this information. These algorithms can process and analyze large datasets more efficiently than traditional methods, identifying trends, and offering predictive insights that can further refine MRV systems.

Customers for Space-Based Carbon MRV Services and Their Motivations
Governments and Public Institutions
Governments are one of the primary customers for space-based Carbon MRV services. Accurate MRV data is essential for tracking progress toward national and international climate goals, setting policy, and implementing environmental regulations. Furthermore, having a reliable MRV system can enhance a country’s reputation in the international arena and may be necessary for participation in carbon trading markets or for receiving climate finance.
Environmental NGOs
Environmental Non-Governmental Organizations (NGOs) may also be interested customers. These organizations often need accurate and reliable data to support their advocacy work, monitor the effectiveness of conservation projects, and hold governments or corporations accountable for their environmental impacts. Space-based MRV provides a level of objectivity and comprehensiveness that can be instrumental for these purposes.
Corporations and Industrial Entities
Companies, particularly those in sectors with high greenhouse gas emissions like energy, manufacturing, and agriculture, could find value in using space-based MRV services. Accurate MRV can assist companies in complying with regulations, participating in carbon markets, and meeting sustainability goals. Corporate Social Responsibility (CSR) efforts can also be substantiated with this data, which can be a selling point for consumers and investors alike.
Research Institutions
Academic and independent research institutions often require high-quality data for climate and environmental studies. Space-based MRV can provide this data at a scale and accuracy that are often difficult to achieve through other means. The data can be used for long-term environmental monitoring, assessing the impact of human activities, and for developing models to predict future changes.
Investors and Financial Institutions
Investors and financial institutions are becoming increasingly aware of the risks associated with climate change. Accurate MRV data can help in the assessment of these risks and provide a basis for investment decisions. This can be particularly important for impact investing, where the aim is to achieve specific environmental outcomes alongside a financial return.
Media Outlets
Journalists and media organizations can use space-based MRV data to report on environmental issues with greater accuracy and objectivity. This data can be used to build compelling narratives around climate change, deforestation, and other environmental crises, thereby raising public awareness and fostering informed debate.
Utility Companies
Companies in the energy sector, particularly those involved in the production of electricity, may find space-based MRV services useful for monitoring emissions from power plants. This information can be important for regulatory compliance and for optimizing the operation of facilities to minimize their environmental impact.
Motivations for Paying for the Service
Regulatory Compliance: Meeting governmental or international standards often requires accurate MRV systems. Failure to comply can result in penalties or restrictions.
Data Integrity: Space-based MRV offers a level of objectivity and coverage that can be difficult to achieve with ground-based methods. This can enhance the credibility of reports and publications.
Strategic Decision-making: Accurate and comprehensive data can inform decisions about business operations, investments, and policy interventions, making the service a valuable asset for various entities.
Transparency and Accountability: For governments, NGOs, and corporations alike, transparent reporting can improve public relations and stakeholder trust.
Financial Gains: Accurate MRV can enable participation in carbon markets, potentially generating revenue or offsetting costs related to emissions.
