The earth’s climate is warming, increasingly straining the Earth’s human and environmental systems. Organisations are increasingly committing to net zero emissions by mid-Century to set and communicate their ambition to limit global warming to the peak temperature goals of the Paris Agreement. However, for many companies, the pathway to delivering against this ambition remains unclear – and significant investment in technical, social and economic systems required before this target becomes a reality. This paper ana [...]

Oil and gas wellbores that are drilled into the earth’s crust need to be plugged and abandoned, to restore the geological seals once they are no longer producing. The main aim of Plugging and abandonment (P&A) is to ensure that there is no leakage of hydrocarbons into the environment. Since offshore P&A is challenging due to subsurface temperature and pressure conditions, testing zeolite as an additive for improvement of cement properties is an intriguing research topic. This initial research aims to establish the [...]

The private sector plays an important role in the global climate goals and the 1.5°C target set during the Paris Agreement. Through investment in green projects and technology and energy efficiency initiatives, their carbon management strategy is paramount to achieve sustainability and good business practices. It is crucial to understand the proposals that the industry has established to reduce its environmental impact by applying supply chain optimization and technological advances or by participating in the carbo [...]

Carbon emissions are a major factor influencing climate change. Climate change also has ecological impacts, such as loss of biodiversity and loss of ecosystem functions and services. Starbucks is a large multinational company which aims to reduce their environmental impact. Starbucks’ carbon emissions in 2018 were 16,706 thousand metric tons, including 320 thousand metric tons of direct scope 1 emissions, 1,094 thousand metric tons of indirect scope 2 emissions and 14198 thousand metric tons of indirect scope 3 emi [...]

Ecologically susceptible zones (ESZs) are endowed with the distinct bio, geo, climatic, hydrological, and ecological integrity that sustain natural resources to support the livelihood of dependent populations. However, globalization and consequent anthropogenic activities have led to the erosion of the natural resource base and enhanced the levels of pollutants, triggering global environmental change, evident from changes in the climate. Alterations in the structure and the ecological integrity of ESZs may lead to [...]

With scientific consensus on climate change and growing public concern, firms are recognising the multiple risks associated with inaction on their Greenhouse Gas (GHG) emissions. The Information and Communications Technology (ICT) and Entertainment & Media (E&M) sectors provide essential communications services, that are foundational for much of the modern world's social and economic systems. The ICT sector has already demonstrated success in innovations that enable emissions reductions. At the same time, the ICT i [...]

Recycled styrene butadiene rubber (rSBR) from waste car tires was used as a filler in poly(lactic) acid (PLA) to modify its properties. The compounds were prepared via twin-screw extrusion and molded by injection with different rSBR contents (0 to 25% wt.). Additionally, recycled rubber particle size was controlled between 125 and 1000 μm to determine the effect of this parameter. From the samples produced, a series of morphological, physical and mechanical characterizations were performed. As expected, rSBR additi [...]

Cyanobacteria are the most ancient phytoplankton that first appeared at least 2.5 billion years ago and have a prolonged evolutionary history. They can form impenetrable and toxic blooms in aquatic ecosystems such as freshwater and marine environments. Cyanobacterial blooms produce cyanotoxins that endanger ecosystem functioning and deteriorate water quality used for recreation, drinking, and in fisheries, thus, adversely affecting human health and the economy. Some bloom-producing genera are Aphanizomenon, Plankto [...]

Awareness of the challenges of sustainable development, and in particular the risks of climate change, is leading to inevitable restrictions on greenhouse gas emissions. Companies must now adopt a systematic approach to sustainable development. This issue is particularly important as true carbon risk management must be introduced into the strategy of companies that will increasingly operate in a global low-carbon economy. Indeed, companies are now called upon to be accountable and transparent about the environment [...]

Our study sought to identify a regional explanation for declining fertility in stocks of co-occurring salmonids in the upper Trinity River, northern California, USA. We focused on evaluating the relationship between thermal variance in river water and hatchery-measured estimates of female fertility as a function of highly managed annual flow regimes. We evaluated annual and seasonal variation in volume of flow and water temperature in response to managed flows associated with annual in-river restoration actions. We [...]
