“…A series of scientific works show that satellite monitoring is a powerful tool for measuring greenhouse gas emissions and concentrations. Mobile systems [55], CubeSats [56], and other satellites like the TROPOMI in China [57] can be used to make these measurements. Satellite monitoring can provide data on a global scale, which can be used to track changes in greenhouse gas emissions over time and to identify sources of emissions.…”

Sustainable development involves constant efforts to reduce pollution by using resources as efficiently as possible. One of the sources of pollution is waste from packaging, recovery, and of course, the possibility of recycling them. The research theme of this paper is the reverse logistics of plastic packaging, which allows the realization of the idea of circular economy and green logistics, which promotes the idea of sustainable development. The EU is strongly committed to issues related to the management of plastic packaging and waste to reduce environmental pollution and achieve circularity goals. Through this article, we aim to highlight the degree to which the EU member states are included in the plastic packaging recycling targets for the year 2030. To highlight the evolution trend for the recycling rate of plastic packaging, we used an advanced forecasting model that runs a series of variables in order to draw up a forecast as accurate as possible. After highlighting the recycling rates for plastic packaging at the level of the EU member states, we proceeded to outline some recommendations in order to encourage the EU member states to make the recycling process more efficient. The current study continues the series of studies dealing with the problem of recycling, but it covers a topic not addressed until this moment, namely the behavior of the citizen regarding the recycling activity seen through the prism of national culture. The current study aims to strengthen the specialized literature in this field and to offer innovative solutions that appeal to the respective national cultures regarding the availability of the populations of the EU member states to address the problem of recycling plastic packaging, not only from a legislative perspective but also from a cultural one. In conclusion, this study generates a model of approach to government policies regarding the recycling of plastic packaging considering the types of national cultures prevailing in the EU member countries, with this being possible by grouping the countries into culturally homogenous clusters. In this way, the environmental policies enunciated by governments can be adapted to convey the message in a more personal way, considering the cultural differences between the EU member states.

“…This spectrometer operates in lines specific to CO 2 (at 1.6 and 2.0 µm) and O 2 (at 0.76 and 1.27 µm), providing a spatial resolution of 250 × 400 km. A recent study [23] also explored the potential of observing GHGs from CubeSats [24]. Such SmallSats, especially in constellation, could play an important role in GHG remote sensing, despite their compact and mass limitations.…”

Climate change is undeniably one of the most pressing and critical challenges facing humanity in the 21st century. In this context, monitoring the Earth’s Energy Imbalance (EEI) is fundamental in conjunction with greenhouse gases (GHGs) in order to comprehensively understand and address climate change. The French Uvsq-Sat NG pathfinder mission addresses this issue through the implementation of a Six-Unit CubeSat, which has dimensions of 111.3 × 36.6 × 38.8 cm in its unstowed configuration. Uvsq-Sat NG is a satellite mission spearheaded by the Laboratoire Atmosphères, Observations Spatiales (LATMOS), and supported by the International Satellite Program in Research and Education (INSPIRE). The launch of this mission is planned for 2025. One of the Uvsq-Sat NG objectives is to ensure the smooth continuity of the Earth Radiation Budget (ERB) initiated via the Uvsq-Sat and Inspire-Sat satellites. Uvsq-Sat NG seeks to achieve broadband ERB measurements using state-of-the-art yet straightforward technologies. Another goal of the Uvsq-Sat NG mission is to conduct precise and comprehensive monitoring of atmospheric gas concentrations (CO2 and CH4) on a global scale and to investigate its correlation with Earth’s Outgoing Longwave Radiation (OLR). Uvsq-Sat NG carries several payloads, including Earth Radiative Sensors (ERSs) for monitoring incoming solar radiation and outgoing terrestrial radiation. A Near-Infrared (NIR) Spectrometer is onboard to assess GHGs’ atmospheric concentrations through observations in the wavelength range of 1200 to 2000 nm. Uvsq-Sat NG also includes a high-definition camera (NanoCam) designed to capture images of the Earth in the visible range. The NanoCam will facilitate data post-processing acquired via the spectrometer by ensuring accurate geolocation of the observed scenes. It will also offer the capability of observing the Earth’s limb, thus providing the opportunity to roughly estimate the vertical temperature profile of the atmosphere. We present here the scientific objectives of the Uvsq-Sat NG mission, along with a comprehensive overview of the CubeSat platform’s concepts and payload properties as well as the mission’s current status. Furthermore, we also describe a method for the retrieval of atmospheric gas columns (CO2, CH4, O2, H2O) from the Uvsq-Sat NG NIR Spectrometer data. The retrieval is based on spectra simulated for a range of environmental conditions (surface pressure, surface reflectance, vertical temperature profile, mixing ratios of primary gases, water vapor, other trace gases, cloud and aerosol optical depth distributions) as well as spectrometer characteristics (Signal-to-Noise Ratio (SNR) and spectral resolution from 1 to 6 nm).

The concentration of carbon dioxide (CO2) is an important indicator for coal mine safety. Real-time monitoring of CO2 concentration is of great importance for taking actions in advance to avoid the occurrence of potential accidents. To address the issues of poor portability and high cost associated with existing coal mine CO2 detection equipment, this paper develops a miniaturized CO2 detection system based on non-dispersive infrared (NDIR) technology. This sensor integrates an infrared light source and a dual-channel pyroelectric detector into a reflective gas chamber, thereby achieving an extended optical path and higher system sensitivity within limited space. Meanwhile, the noise interference was greatly mitigated by using hardware and software filtering techniques. Based on principle analysis, the Lambert–Beer law was parametrically corrected, and then, a model relationship between the dual-channel voltage ratio and concentration was established. In addition, temperature compensation for zero and span values was introduced to improve the adaptability of the detection results to temperature changes. Testing results indicate that the developed detection system can realize CO2 measurement in the concentration range of 0 to 50 000 ppm within a temperature range of 0–40 °C, with a maximum detection error of less than 0.12% and a repeatability deviation of less than 1.04%. During a stability test for 12 h, the maximum concentration drift is 0.07%, indicating that the developed system meets the requirements for monitoring CO2 safety in coal mines.
