Sub-Saharan Africa is greatly affected by global warming and is the most affected region in the world. Although several studies in the literature have attempted to identify the causative agents and recommendations to the environmental damages, the gap remains unfilled as the situation is still not any better. This study contributes to the existing body of knowledge through the investigation of the role of governance, energy consumption and population on the environmental quality in Sub-Saharan Africa using data spanning over the period 1998-2014 for 46 countries in the region. For the empirical analysis, the system-generalised method of moments (S-GMM) is employed to analyse the model. Findings from the study reveal that while the total population has a negative but insignificant impact on emissions, the urban population has a positive and statistically significant impact on emissions. The moderation effect of governance is found to overturn the adversities of the urban population on emissions, but this effect is statistically insignificant. The study recommends proper and strategic management of population pressure in urban centres to mitigate its impact on emissions.

Background: Vascular inflammation persists in temporal artery biopsy (TAB) of giant cell arteritis (GCA) patients even after prolonged glucocorticoid (GC) therapy. We aimed to evaluate the histological impact of adding tocilizumab (TCZ) to GCs.
Methods: We enrolled all consecutive GCA patients with an inflammed TAB at diagnosis who were treated with TCZ and GCs for ≥6 months and followed from December 2017 to December 2023.

Nutrient enrichment of water bodies can lead to eutrophication, which poses a global threat to freshwater ecosystems, affecting biodiversity and water quality. While human activities have accelerated eutrophication, climate change further complicates the dynamics of nutrient cycling and ecosystem responses. Here, we provide global, spatially explicit freshwater eutrophication characterization factors, at an annual resolution from 2021 up to 2099 based on eight different climate change scenarios.

Ships generate large amounts of air pollutants, including nitrogen dioxide (NO) that profoundly impacts air quality and poses serious threats to human health. It is crucial to understand the dynamics and drivers of ship-induced NO concentrations in China to support the prevention and control of fine particulate matter (PM) and ozone (O) pollution. This study built Generalized Additive Models (GAMs) to reveal the nonlinear effects of meteorological factors and ship emissions on ship-induced NO concentrations based on the Tropospheric Monitoring Instrument (TROPOMI) satellite data, AIS based emission model and meteorological data.

This study investigates the relationship between corporate energy efficiency (EE) and financial performance (FP), emphasizing the moderating role of environmental concerns. Grounded in the Enlightened Value Maximization (EVM) and Natural Resource-Based View (NRBV) theories, the research hypothesizes that the EE-FP relationship strengthens in the presence of environmental concerns. Utilizing firm-level data, the analysis incorporates marginal effect analysis to explore how incremental improvements in environmental management and emissions management practices impact financial outcomes.

The global situation of carbon reduction is very severe, and the coupling of digital and green technology innovation is one of the most significant approaches to promoting regional low-carbon transformation. A coupling evaluation model is employed to assess the coupling index between digital technology innovation and green technology innovation in China's 30 provinces from 2011 to 2021. The STIRPAT model is used to examine the impact of the increasing coupling index on carbon emissions, as well as its spatial effects, and heterogeneity.
