Can TROPOMI-NO2 satellite data be used to track the drop and resurgence of NOx emissions between 2019 - 2021 using the multi-source plume method (MSPM)?

NOx is an important primary air pollutant, dominantly produced by anthropogenic, mostly combustion based, activities from sectors such as industry, traffic and transport. NOx is directly linked to negative health and environmental impacts. Currently, the construction of emission inventories to keep track of NOx emissions is based on official national reported emissions and prOxies such as activity data as well as direct measurements. The effort to properly construct an accurate inventory is significant and time consuming which causes a reporting offset between one and five years with respect to the current date. Next to this temporal lag difficulties in composed inventories can arise from legislative and protocol differences between countries and over time in reporting of emissions. Satellite based atmospheric composition measurements provide a unique opportunity to fill this gap and independently estimate emissions on a large scale in a consistent, transparent and comprehensible way. They give the possibility to check for compliance with emission reduction targets in a timely manner as well as to observe rapid emission reductions such as experienced during the COVID-19 lock-downs. In this study we apply a consistent methodology to derive NOx emissions over Germany for the years of 2019-2021. For the years where reporting is available differences between satellite estimates and inventory totals were within 100kt. The large reduction of NOx emissions related to the COVID-19 lock-downs were observed in both the inventory and satellite derived emissions. The recent projections for the inventory emissions pointed to a recovery of the emissions towards pre-COVID19 levels this increase was not observed. While emissions from the larger power-plants did rebound to earlier levels, others sectors such as road transport and shipping did not and could be linked to a reduction in the number of heavier transport trucks. This again illustrates the value of having a consistent satellite based methodology for faster projections to guide and check the conventional emission inventory reporting. The method described in this manuscript also meet the demand for independent verification of the official emission inventories, which will enable inventory compilers to detect potentially problematic reporting issues. Transparency and comparability, two key values for emission reporting, are thus bolstered by this technique. [ FROM AUTHOR]

Satellites to protect the world, if data is open to all

Speed read Benefits of satellite tech for world’s poorest and the planet could be boundless – if data is open to all Demand for resources to build satellites could put vulnerable communities, indigenous land rights at risk Future challenges remain, such as need for infrastructure, uneven distribution between countries Satellite technologies are a new frontier in global development. Satellites are being used for everything from monitoring illegal fishing to tracking malaria, from supporting early warning systems in flood-prone nations to measuring crop yields and giving farmers advice on fertilisers. Nomadic communities in Africa are using space technology and mobile phone networks to go where the water is and avoid violent conflicts in the Sahel related to climate change and food insecurity.

Improving the Customs Regulation Framework in the Eurasian Economic Union in the Context of Sustainable Economic Development

The formation of a customs administration framework based on the digital economy in the Eurasian Economic Union (EAEU) requires the application of fundamentally new technologies. The successful implementation of digital technologies in the information space of the EAEU presupposes the solution of a number of problems associated with the ensuring the implementation of the concept of sustainable development of the EEU member states in the new economic reality and transition to a new paradigm of customs administration based on the digitalization of the processes of regulation of foreign economic activity. Based on this paradigm, we set the following tasks: to identify trends and substantiate the need for digitalization of the customs administration mechanism in the Eurasian Economic Union based on the use of new technologies;to reveal the meaningful features of digital technologies that are promising for the development of the mechanism of customs administration of the EAEU;consider the applied aspects of the latest information technologies used in the course of EAEU customs administration system digitalization;and assess the prospects for their use, analyze the prospects of organizational, legal and managerial support of this process in the EAEU at the supranational and national levels. The article concludes that within the framework of the digital transformation of the EAEU, new opportunities are opening up for the customs regulation framework, based on the introduction of technologies for analyzing large amounts of data, immersive technologies, blockchain, the use of innovative methods for obtaining and processing customs information (satellite tracking, radio frequency identification), and the introduction of artificial intelligence technologies in customs control processes.
