In recent decades, climate change has become one of the largest challenges we face as a planet. With the rise in global average temperatures, it has become essential to understand how human activities affect our environment. Since the launch of the first artificial satellite, Sputnik, over 70 years ago, space technology has provided us with a wealth of data about our planet. In this context, the “Monitoring Carbon Dioxide Emissions from Human Activities” (CO2M) project comes as a pivotal step toward improving the measurement of greenhouse gas emissions. In this article, we explore how this modern space mission will contribute to providing a more accurate picture of carbon emission sources, helping nations and companies take effective steps to mitigate the effects of climate change. Let’s delve into the details of this ambitious mission and how it could change our understanding of our impacts on Earth’s climate.
History of Earth Observation from Space
The roots of Earth observation from space trace back to the launch of the first satellite, Sputnik, over 70 years ago. Since then, numerous satellites have been launched to monitor the Earth, giving us a unique opportunity to see our planet as a beautiful disk made up of white clouds, blue oceans, and colorful continents. These space programs were not mere tactics for exploring outer space; they significantly contributed to enhancing our understanding of climate change and the human impact on it. By combining satellite data with ground weather measurements, scientists have been able to build a comprehensive picture of the climate and how human activities affect it. Over the years, we have learned that global temperatures are continuously rising, a direct result of emissions from burning fossil fuels. This situation is highly unsustainable for the Earth, as carbon dioxide emissions are a key factor in this process.
The Paris Agreement and Countries’ Commitments
In December 2015, Paris witnessed the signing of a binding international agreement to combat climate change, with 196 countries coming together to agree on a main goal of keeping global temperatures below a 2-degree Celsius increase. This agreement requires countries to disclose the amount of carbon dioxide emissions resulting from human activities, as well as the measures they are taking to reduce these emissions. This step is a crucial framework for achieving international cooperation in the face of climate change. Similarly, countries around the world are working to identify and track emission sources to stay on track to meet their climate goals, with precise calculations being made to understand the impact of their energy needs and fuel sources, and how these factors affect both local and global environments.
European Space Agency’s Carbon Dioxide Monitoring Mission
The European Space Agency is preparing to launch a new carbon dioxide monitoring mission, known as CO2M. This mission is set to incorporate advanced technologies that allow for unprecedented precision in measuring carbon dioxide emissions. This mission is part of the Copernicus program, which aims to enhance understanding of human emissions and utilize data to help manage carbon emissions. This technology enables scientists to monitor greenhouse gas emissions with high accuracy, identify their sources, and trigger necessary actions to reduce these emissions. For example, thanks to CO2M, scientists will be able to learn how gases interact with surrounding plants and how human activities affect their concentrations in the atmosphere.
Scientific and Technical Challenges in Measuring Carbon Emissions
Measuring carbon emissions poses significant engineering and scientific challenges. Although some previous satellites have managed to provide accurate data on a small or broad scale, CO2M combines both aspects by relying on high orbits that enable it to cover vast areas with exceptional precision. Tracking changes in greenhouse gas concentrations also involves advanced analyses of environmental differences. Another challenge to address is distinguishing between natural and human emissions amidst the complex interactions between the atmosphere and the environment. When carbon dioxide is emitted, it quickly disperses in the atmosphere, making it a real challenge to pinpoint its source. To tackle this issue, scientists will need to use complex computational models to adjust for natural variations in concentrations to ensure accurate reporting of emissions.
Impact
Data on Future Mitigation Efforts
The benefits of the CO2M mission will not be limited to providing accurate data for countries to meet their emissions commitments; they will also be used by many individuals and companies to demonstrate their efforts in achieving environmentally positive outcomes. By providing comprehensive maps of greenhouse gas emissions, local authorities will be able to verify the efficiency of their carbon emissions. Additionally, actionable data will provide companies and researchers with innovative tools that enable them to improve sustainable business strategies. As climate change remains one of the greatest challenges facing humanity, the data derived from this mission will vitally assist in guiding public policies and making informed decisions to address this issue.
Investment in Green Infrastructure
Green infrastructure is a fundamental element of environmental protection efforts. Financial institutions are increasingly focusing on verifying their investments in such projects by providing clear evidence and accurate measurements of greenhouse gas emissions. These steps not only indicate the commitment of institutions to sustainability but also represent a significant shift in environmental monitoring from space. Dr. Simon Penock, application engineer for Earth observation at the European Space Agency’s climate office, has witnessed tremendous advancements in Earth observation technologies throughout his career, which began in the mid-1990s. At that time, environmental monitoring tools were not fully available, but today, thanks to satellites like “Sentinels,” comprehensive and practical environmental monitoring is possible.
Advancements in monitoring carbon emissions and climate change have become a standard for evaluating progress in environmental investments. Projects undertaken by these institutions aim to gather reliable data for analyzing climate changes and their impacts on the environment. With advanced technologies, such as satellites that cover the atmosphere, it has become possible to measure carbon dioxide emissions accurately, aiding in strategic decision-making related to the environment. This approach allows for scientific evidence to support environmental and international policies related to climate change, where the available data become the cornerstone of sustainable development.
Climate Change and Satellite Monitoring
The growing interest in climate change is driving the development of new initiatives to gather and analyze data. Under the European Space Agency’s “Climate Change Initiative,” focus is placed on 55 key climate variables, with data collected on these variables from multiple sources, including satellites. Dr. Penock points out that about 60% of this data comes from satellites, while the remainder is gathered from ground observations. This information is not just numbers; it forms the basis for understanding global climate changes.
Data collected from satellites is a critical component in adaptation strategies to mitigate the effects of climate change. Without precise measurements, providing the necessary evidence to formulate effective policies is challenging. The European Space Agency has developed a system to support the decision-making process by providing accurate and comprehensive information that contributes to real-time monitoring of environmental changes. This advancement is vital to securing the future of our planet, as it helps us understand how human activities impact the environment.
The Copernicus Program and Earth Monitoring
The Copernicus program is one of the largest providers of Earth observation data in the world. With the development of a suite of satellites dedicated to monitoring various aspects of the environment, the program showcases the importance of international cooperation in addressing environmental challenges. This program is implemented by the EU member states, in collaboration with the European Space Agency and other organizations. Despite the United Kingdom’s exit from the program after “Brexit,” a special agreement allowed it to join again, highlighting the significant global importance of this program.
