Carbon Footprint Reduction and Climate Change Mitigation
Since the Industrial Revolution, human economic activity and the global development of society in general have been heavily dependent on the exploitation of natural resources. The use of fossil fuels, deforestation, the drainage of wetlands, the transformation of coastal marine ecosystems, unsustainable land use, and many other unbalanced processes of human activity have led to an increase both in the anthropogenic emissions of climate-active gases and in their concentration in the atmosphere. It is believed that over the past ~150 years these phenomena have contributed to an increase in the global average temperature in the near-surface layer of the atmosphere by ~1 °C. Currently, the most pressing tasks facing states and scientific and civil societies are to reduce anthropogenic CO2 emissions and to limit the global air temperature increase. In this regard, there is an urgent need to change existing production systems in order to reduce greenhouse gas emissions and to sequester them.

Measure the Height of Mount Everest
Mount Everest is the highest mountain in the world. First, we should know where is Mt. Everest located on the plateau of Tibet map. It is on the border of Nepal and Tibet(the Autonomous Region of China). The determination of the height of Mount Everest(HME) is one of the focuses of the geodetic community. The shallow layer method (SLM) based on the definition of the geoid can determine the gravity field inside the shallow layer. The orthometric height of Mount Everest (HME) is calculated based on SLM, in which the key is to construct the shallow layer model. The top and bottom boundaries of the shallow layer model are the natural surface of the Earth and the surface at a certain depth below the reference geoid, respectively.

Achieving Climate Neutrality in Europe through Decarbonization Strategies
Various studies have been conducted in the fields of sustainable operations management (SOM), optimization, and wastewater treatment, yielding unsubstantiated recovery. In the context of Europe’s climate neutrality vision, effective decarbonization strategies and sustainable approaches to mitigate carbonization in various sectors such as buildings, energy, industry, and transportation and how these interlink with wastewater management are discussed.

State of Knowledge Concerning Wastewater Treatment System Landscapes
Around the world, human populations and their supporting infrastructures are concentrated in coastal areas. With rising sea levels, these settlements and urban infrastructures are at risk of service interruptions, lasting damage and frequent climate-related hazards. Wastewater systems are especially vulnerable due to their proximity to coastlines. Despite the seriousness of sea-level-rise-induced challenges, a clear understanding of the risks and potential adaptations of coastal wastewater treatment systems and their associated landscapes in Australia has been overlooked.

Global Gas and Liquefied Natural Gas Markets
Market volatility is a key driver of energy security concerns. It can potentially disrupt the supply of energy resources, leading to price spikes and market imbalances. The COVID-19 pandemic has also contributed to market volatility in the energy sector, as the global economic slowdown has reduced demand for oil and gas, leading to a drop in prices. The global gas and liquefied natural gas (LNG) markets have experienced significant growth over the past few years, driven by the increasing demand from Asia and the adoption of gas in heavy-duty transport.

QR/IoT-Assisted Trash Collection System
Effective waste management is of paramount importance as it contributes significantly to environmental preservation, mitigates health hazards, and aids in the preservation of precious resources. Conversely, mishandling waste not only presents severe environmental risks but can also disrupt the balance of ecosystems and pose threats to biodiversity. The emission of carbon dioxide, methane, and greenhouse gases (GHGs) can constitute a significant factor in the progression of global warming and climate change, consequently giving rise to atmospheric pollution. This pollution, in turn, has the potential to exacerbate respiratory ailments, elevate the likelihood of cardiovascular disorders, and negatively impact overall public health. Hence, efficient management of trash is extremely crucial in any society. It requires integrating technology and innovative solutions, which can help eradicate this global issue. The internet of things (IoT) is a revolutionary communication paradigm with significant contributions to remote monitoring and control. IoT-based trash management aids remote garbage level monitoring but entails drawbacks like high installation and maintenance costs, increased electronic waste production (53 million metric tons in 2013), and substantial energy consumption for always-vigilant IoT devices.

Adopting Energy Policies of BRICS for South Africa
At its inception in 2006, there were four BRIC member countries comprising Brazil, Russia, India and China. In 2010, South Africa was invited to become a member of BRIC, which then evolved into BRICS, forming a new alliance of these five member countries. South Africa joined in December 2010 to promote peace, security, economic development and cooperation amongst these countries. The main objective was to contribute significantly to improving the socio-economic landscape of these five member countries, which have over three billion people. This is approximately 40% of the global population, and they account for approximately 25% of the world’s gross domestic product (GDP).

Climate Change and Indigenous Persons
Indigenous actors have a myriad experiences because of the wildly different areas they inhabit across the globe and they bring a wide variety of experiences that Western science is beginning to include in its research of climate change and its solutions.

Contamination of Poly-Fluoroalkyl Substances in Environment and Food
More than 7000 synthetic compounds known as per- and poly-fluoroalkyl substances (PFAS) are applied to food packaging and other materials to provide fat, fire, and/or water resistance properties. These compounds have exceptional environmental stability and persistence due to the strong C-F chemical bond, earning them the moniker “forever chemicals”. Emission of PFAS from industrial waste leads to water, air, and soil contamination.

Sustainable Use of Plastics in Horticulture
The sustainable use of plastics in horticulture is investigated based on 4 criteria, the three Rs (reduce, reuse, and recycling) plus a re-place strategy, taking into account possible alternatives to plastics. Hail (and insect) nets made of HD-PE, with their long-term use mostly on apple and polytunnels of LD-PE for cherry and strawberry as well as solarisation mulches (reuse), were found to be relatively sustainable solutions for their needs and are currently without alternatives. In contrast, standard black mulch, with its largest share among horticultural plastics, had the widest range of sustainable alternatives, ranging from biodegradable to spray mulch; few sustainable alternatives are available for fleeces and reflective mulches. For the third sustainable option, pilot recycling schemes were examined, such as PolieCoTM (Italy), MAPLATM (Spain), and ERDETM (Germany); they collect 30–50% of the agricultural plastics used in their respective areas, with a successful retrieval growth rate of ca. 20% per year in the case of ERDETM. For the fourth new R option (replace), future sustainability perspectives for the predominant black mulch are research into and development of better, biodegradable, non-fossilbased plastics, sprayable mulch; microbes for the digestion of deployed polyolefins and, for a certain limited range (on shade tolerant crops or in high-light intensity environment), hail nets and polytunnels that are equipped/substituted by/with solar panels (“agri pv”) for the concomitant sustainable production of green renewable energy.
