“…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.

Worldwide, the increase in land surface temperature has been attributed to the concentration of greenhouse gases. However, there is no record of timely information that shows which types of land cover relate to major increases in surface temperature. The main aim of this paper is to identify the specific sites in a landfill where biogas is released into the atmosphere. A second objective is to try to find a spatial correlation between the concentration of methane emitted to the atmosphere with the observed surface temperature gradients. The recoverable and fugitive methane fluxes were validated with in situ information, using a LICOR gas accumulation chamber. The surface heat estimate was obtained from the Split Window algorithm, using the TIRS sensor of the Landsat 8. With data obtained in previous studies, both in situ and remote, it was possible to spatially correlate the methane flux released into the atmosphere with the temperature distribution plume within the landfill. The importance of our research is related to the continuous need for surface temperature monitoring on the planet. The use of technological tools such as the one presented here reduces the cost and execution time of environmental studies.

“…However, the spatiotemporal variations of CH 4 emissions have not been well understood [6]. For instance, China is a major CH 4 emitter but has not yet compiled its own CH 4 emission inventory [7]. Satellite data are important for emissions, mainly through the top-down method, which is complementary to the bottom-up inventory.…”

Methane (CH4) is an important greenhouse as well as a chemically active gas. Accurate monitoring and understanding of its spatiotemporal distribution are crucial for effective mitigation strategies. Nowadays, satellite measurements are widely used for CH4 studies. Here, we use the CH4 products from four commonly used satellites (GOSAT, TROPOMI, ARIS, and IASI) during the period from 2018 to 2020 to investigate the spatiotemporal variations of CH4 in China. In spite of the same target (CH4) for the four satellites, differences among them exist in terms of the instrument, spectrum, and retrieval algorithm. The GOSAT and TROPOMI CH4 retrievals use shortwave infrared spectra, with a better sensitivity near the surface, while the IASI and AIRS CH4 retrievals use thermal infrared spectra, showing a good sensitivity in the mid–upper troposphere but a weak sensitivity in the lower troposphere. The GOSAT and TROPOMI observe high CH4 concentrations in the east and south and low concentrations in the west and north, which is highly related to the CH4 emissions. The IASI and AIRS show a more uniform CH4 distribution over China, which reflects the variation of CH4 at a high altitude. However, a large discrepancy is observed between the IASI and AIRS despite using a similar retrieval band, e.g., significant differences in the seasonal variations of CH4 are observed between the IASI and AIRS across several regions in China. This study highlights the CH4 differences observed by the four satellites in China, and caution must be taken when using these satellite products.
