ABSTRACT This study aims to enhance academic understanding of the factors influencing the disclosure practices of climate change among European utility companies, specifically in the context of their sustainability reporting. The primary objective is to explore, through a multi‐theoretical framework, the governance drivers that significantly affect the

Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Fractional advection differential equation within Caputo and Caputo–Fabrizio derivatives
In this research, we applied the variational homotopic perturbation method and q-homotopic analysis method to find a solution of the advection partial differential equation featuring time-fractional Caputo derivative and time-fractional Caputo–Fabrizio ...

Ethical Behaviour and Corporate Financing. The Case of ‘Legality Rating’
ABSTRACT The financial crisis has heightened awareness of ethical and legal issues in the business context. Corporate ethical behaviour is increasingly measured through sustainability ratings. Since 2012, in Italy, the introduction of a sustainability rating, namely the legality rating (LR), has served as an innovative ‘label’ for socially responsible ...
