Purpose

Considering environmental, social and governance (ESG) factors is vital in climate change mitigation. Energy companies must incorporate ESG into their business plans, although it unquestionably affects their corporate financial performance (CFP). This paper aims to investigate the effect of ESG on energy companies’ profitability through return on assets by analysing the combined score and individual dimensions of ESG.

Green roofs are artificial ecosystems that provide a nature-based solution to environmental challenges such as climate change and the urban heat island. Green roofs aid in the conservation of both cooling and heating energy; deposition of particulates and mitigation of air pollution; control of runoff and water pollution; promotion of biodiversity; and provision of aesthetic and health benefits. This research is a holistic review of the green roof literature and provides a global perspective of the subject with a classification of modelling studies; and an extensive review of contributions to energy conservation, carbon sequestration, mitigation of air pollutants, runoff control; and urban noise reduction. The review covers the system’s thermal performance modelling through several methodologies; experimental studies; parametric studies to assess the impact of various parameters on the system’s energy efficiency using several configuration parameters such as leaf area, foliage height and density, plant coverage, roof insulation, soil thickness, and irrigation; energy benefits; and environmental benefits including air pollutants mitigation, carbon sequestration, runoff control and urban noise reduction. Finally, review was complemented with a life cycle assessment study of green roofs, which examined the extraction of raw materials, manufacturing and construction, transportation, and disposal.

The Intersection of Neurochemistry and Environmental Cognition in Climate Change

Let me introduce you to the concept of relativity, particularly relative status. Why can we not stop consuming? A first hint is the very nature of human survival and social structures. Within these social structures, hierarchy and hence status is particularly important. However, we have not evolved to have an absolute criterion for reaching a certain status, as it wouldn’t be viable on largely different scales. That is why we rely on relative status. As you may already know, our brain relies on neurotransmitters to carry electrical signals from one neuron to the next.

Are We Creating a Compromise?

Every year in the United Kingdom and Australia, thousands of incidents involving devastating fires linked to batteries in waste management facilities or vehicles are reported. Paradoxically, these are facilities meant to contain such hazardous activities. Furthermore, headlines such as “Batteries Starting Fires at Yellowknife’s Landfill, City Says,” posted by Cabin Radio, report unreported hazardous incidents potentially linked to batteries, and are becoming more common around the globe. These reports and news are increasingly alarming because they come at the cost of life, property damage, and monetary losses, and given the fact that we heavily rely on batteries for the energy transition, they could lead to safety and environmental compromises if not treated properly.

Driving the Paris Agreement

Article 6 of the Paris Agreement includes provisions allowing countries to cooperate to achieve National Determined Contributions (NDCs), specifically through carbon pricing, to meet mitigation commitments. Carbon markets are an emerging tool that incentivises businesses to pollute less and invest in clean technologies by putting a price on carbon emissions. As this article explores further, compliance and voluntary carbon markets are poised to reshape the energy landscape and contribute to achieving the ambitious goals of the Paris Agreement.

Compliance Carbon Markets

Compliance carbon markets are a key tool in the fight against climate change, and they aim to establish a carbon price by laws or regulations which control the supply of allowances distributed by national, regional and global regimes through the following compliance mechanisms: (1) Cap and Trade: Sets a pollution limit (the cap) and lets companies buy or sell allowances to meet their obligations, creating a market for carbon credits with a price driven by supply and demand; (2) Carbon Tax: A fixed price is set per ton of carbon emitted. Companies must pay tax for their emissions, incentivising them to reduce pollution.

The United Kingdom is in the right place to become a global leader in the industrial Carbon Capture, Utilisation and Storage (CCUS) sector. Specific, UK associated industrial development has set a great potential for Industrial Carbon Capture (ICC) application. In fact, the operation of Oil and Gas (O&G) offshore fields has allowed for decades of data on suitable carbon storage sites to be collected, determining that the North Sea’s saline aquifers and depleted reservoirs have a 78,000 MtCO₂ capacity. Figure 1 exhibits the distribution of both CO₂ emission sources from industrial clusters and offshore storage points.

On Thursday 24 November 2022, Renault signed a contract with Voltalia to supply 350 MW of renewable energy over 15 years from 2027, which should account for half the company’s electricity consumption. This type of contract, also known as a corporate Power Purchase Agreement (cPPAs), is an unprecedented commitment in France in terms of power. On the same day, Engie announced a contract to purchase 100MW with Google in the United Kingdom for 12 years from the Moray West offshore wind project off Scotland. Whilst solar and wind remain dominant, contracts are now emerging for biogas, geothermal, and even hydrogen

Funding for the energy industry has historically been dominated by major private or state-controlled institutions. Conventional energies such as fossil fuels require capital outlays of millions and sometimes billions of euros, and hence, understandably, citizens or cooperatives have never fully financed a nuclear powerplant or an offshore oil rig. As the urgency of tackling climate change increases, the energy sector is being reconfigured by financing alternatives made possible by renewable energy technologies that are adaptable to local and community investment. Society is simultaneously becoming increasingly electrified, with global electricity consumption forecast to double from 2021 levels, reaching 50,000 TWh by 2050. Rapid growth in the renewables sector will be crucial for meeting this steady increase in demand.

With Putin’s “special military operation” into Ukraine on February 24^th 2022 it became clear to many observers within a week that this was a war. It represented a step change from the various territorial incursions over the past few decades which had gone under the term “New Cold War”. “The New Cold War” was the title of a book (one of several) first published in 2008 sub-titled: “How the Kremlin Menaces both Russia and the West” authored by Edward Lucas. Lucas was the Central and East European correspondent of The Economist for more than 25 years. 

Over recent years, the European Union has been increasingly exploring new alternative routes and sources for natural gas due to energy security concerns, mostly associated with the Russian - Ukrainian circumstances and the significant role which natural gas is expected to have in the future. Currently it is considered as "the transition fuel" to the future green-energy reality.

The objective of the Special Issue is to present new research results on the theory and modern practice of modeling and management of energy systems, emphasizing on their policy implications. The areas of interest include, networks design and management, oil and gas, smart grids, production optimization, efficiency analysis, optimization and assessment of renewable and sustainable/green energy systems, environmental issues, risk management, decision-making in the energy markets, and energy pricing, among others.

The fundamental idea of this technical paper is to understand the feasibility and present the robustness of removing the need to decommission an offshore jacket and instead installing an offshore wind tower (with nacelle, rotor blades and generator) on top of it, thereby saving the costs of decommissioning as well as entirely removing the need to design, build and install a substructure for the new offshore wind tower. The economics of scalability are particularly interesting.

The world is currently experiencing one of the worst energy crises in history. Countries all over the world are beginning to adopt greener strategies by funding and covering their energy needs with green and renewable energy sources. Each of these countries has its own rate of development, but they all share a common goal of achieving carbon neutrality by 2050. In comparison, the European Union appears to have a faster development rate and a different goal, particularly regarding neutrality, of covering all its member states' energy needs with shareable green energy.
