Abstract
Fairness is central to any multilateral regime, that is, any agreement between multiple nation-states to address and resolve a common problem. Climate change mitigation is among the key global environmental concerns that will require a common agenda, approach, and set of actions by the community of nations. To that end, global climate negotiations under the United Nations Framework Convention on Climate Change (UNFCCC, 1992) are centered on establishing a multilateral framework to control greenhouse gas (GHG) emissions from all nations and to help those who would be affected by climate change.

Abstract
Purpose
Low nickel austenitic stainless steel (ASS) has attracted much attention worldwide because of its economical price. This study aims to investigate the effect of different corrosive environments on the corrosion behavior of chrome-manganese (Cr-Mn) ASS. The tests were carried out as a function of H2SO4 concentrations, temperature and addition of ammonium thiocyanate (NH4SCN) (0.01 M). Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques were used to study the corrosion behavior of Cr-Mn ASS. It was observed that with increasing H2SO4 concentration, temperature and with the addition of NH4SCN solution, icorr, icrit and ipassive values increased. EIS data show decreasing charge transfer resistance value with increasing concentration and temperature. Higher corrosion rate with increasing temperature and concentration of H2SO4 is related to the anions (SO42−), which is responsible for reducing the stability of passive films. With the presence of 0.01 M NH4SCN thiocyanate (SCN− anion), there is a higher dilution of the passive film resulting in a higher corrosion rate. Energy-dispersive spectroscopy (EDS) analysis reveals the adsorption of sulfur on the surface in NH4SCN containing a solution. The significant presence of counter ions and the adsorbed sulfur species on the steel surface play a vital role in corrosion behavior.
Design/methodology/approach
All the experiments were performed on a 3 mm thick sheet of Cr-Mn ASS (202 ASS) in hot rolled condition. The samples were then annealed at 1,050°C for 1 h, followed by water quenching. For microstructural examination, they were electrochemically etched in 10 Wt.% oxalic acid solution at 1 amp for 90 s. A computer-controlled Potentiostat (Biologic VMP-300) was used. After the cell was set up, the working electrode (WE) was electrostatically cleaned at −1 V vs saturated calomel electrode (SCE) for 30 s to remove the air-formed film. Then, WE were allowed to attain stable open circuit potential (OCP) for 1 h, following by the EIS test and potentiodynamic polarization test. The polarization test was started from a cathodic potential (−1.2 V vs SCE) and continued up to an anodic potential (1.6 V vs SCE) a scan rate of 0.1667 mV/s. EIS experiment was conducted on the same instrument by using a sinusoidal AC signal of 10 mV in a frequency range of 1,000,000 to 0.01 Hz at OCP.
Findings
Potentiodynamic polarization graph shows that with the increase in sulphuric acid concentration. Increasing temperature from 20°C to 80°C in 0.5 M H2SO4 solution increases the corrosion rate (icorr) of Cr-Mn ASS. On the addition of 0.01 M NH4SCN to the sulfuric acid solution (0.1, 0.5 and 1 M) the corrosion rate increases drastically almost four to five times. EDS and XRD analysis shows the presence of sulfur over the oxide film and preferential site for dissolution of Cr and Mn at the steel surface when NH4SCN is added to the sulfuric acid solution.
Originality/value
A study on the corrosion behavior of Cr-Mn ASS is scanty according to the author’s knowledge. Therefore, the present study will investigate the corrosion behavior of Cr-Mn ASS on SO4−2 anions, temperature and the addition of SCN− ion in sulfuric acid.

Abstract
Purpose
India began gas imports since 2004 through liquified natural gas (LNG) route. Imports through trans‐country gas pipelines could help in bringing gas directly into the densely populated Northern part of India, which are far from domestic gas resources as well as coastal LNG terminals. The purpose of this paper is to report scenarios, which quantify the impacts for India of regional cooperation to materialize trans‐country pipelines. The analysis covers time period from 2005 to 2030.
Design/methodology/approach
The long‐term energy system model ANSWER‐MARKAL is used for the analysis.
Findings
Trans‐country pipelines could deliver direct economic benefit of US$310 billion for the period 2010‐2030. Besides these, there are positive externalities in terms of lower greenhouse gas emissions and improved local environment, and enhanced energy security. However, the benefits are sensitive to global gas prices as higher gas prices would reduce the demand for gas and also the positive externalities from using gas.
Practical implications
Trans‐country pipelines are of great importance to India as they add 0.4 per cent to gross domestic product over the period besides yielding positive environmental externalities and improved energy security.
Originality/value
Quantification of benefits from trans‐country pipeline proposals till 2030.

Abstract
Purpose
This study aims to examine the role of creativity and proactive personality to predict entrepreneurial intentions (EIs) using Ajzen’s (1991) theory of planned behaviour as an underpinning model. The study primarily focuses on how entrepreneurial self-efficacy and passion mediate the effect of creativity and proactive personality on EI.
Design/methodology/approach
A total of 531 college students of 18–28 years of age were surveyed using a structured questionnaire. The proposed model was tested using structural equation modelling in Amos 20.0, and the mediating effect of entrepreneurial self-efficacy and entrepreneurial passion was tested using the bootstrapping method.
Findings
The results validate the extension of the theory of planned behaviour to predict EIs and confirm that the effect of creativity and proactive personality on EIs through entrepreneurial self-efficacy was fully and partially mediated, respectively. Moreover, the relationship between entrepreneurial self-efficacy and the EI was partially mediated by entrepreneurial passion.
Practical implications
The study provides a better understanding of college students' EI and identifies and highlights the role of social factors (i.e. subjective norms) and psychological factors such as attitude, self-efficacy, creativity, proactivity and passion in stimulating EIs. It deciphers the interlink of creativity, proactive personality, self-efficacy, passion and EIs. It may help academicians and policymakers better plan the educational programme to foster entrepreneurial instinct among students.
Originality/value
The study is a novel attempt to provide an integrated framework to explain EIs, highlighting the significance of creativity and proactive personality. It contributes to the existing literature by signifying the mediating role of entrepreneurial self-efficacy and passion.

Abstract
Purpose
This paper aims to present a high-order scheme to approximate generalized derivative of Caputo type for μ ∈ (0,1). The scheme is used to find the numerical solution of generalized fractional advection-diffusion equation define in terms of the generalized derivative.
Design/methodology/approach
The Taylor expansion and the finite difference method are used for achieving the high order of convergence which is numerically demonstrated. The stability of the scheme is proved with the help of Von Neumann analysis.
Findings
Generalization of fractional derivatives using scale function and weight function is useful in modeling of many complex phenomena occurring in particle transportation. The numerical scheme provided in this paper enlarges the possibility of solving such problems.
Originality/value
The Taylor expansion has not been used before for the approximation of generalized derivative. The order of convergence obtained in solving generalized fractional advection-diffusion equation using the proposed scheme is higher than that of the schemes introduced earlier.

Abstract
The global energy transition is a process without historical experience that affects all participants in the technological chain of energy management, citizens and business entities. This increasingly dynamic process is aimed at decarbonisation of the entire economy, social stability and human well-being. We are witnessing the rapid development of more energy-efficient technologies, clean energy sources and stricter rules regarding the greenhouse gas (GHG) emissions. The data clearly show changes in the Earth’s climate system. Their consequences represent the most urgent threat to the longevity of tourism, which is one of the five most threatened economic sectors. At the same time, tourism continues to have a significant contribution to climate change due to growing GHG emissions, primarily from transport and accommodation facilities.
This chapter seeks to provide an overview of the drivers of GHG emissions and societal responses aimed at addressing tourism-related carbon emissions. It also offers an overview of climate and energy public policies and possible solutions towards a net-zero carbon future for the tourism industry. The purpose of this review is to empower tourism practitioners with current knowledge funded in global and European decarbonisation strategies and encourage them to reflect and create a new and more effective solution.

Abstract
Purpose
The purpose of this paper is to discuss the synthesis of polyesteramide resin from the monomer obtained from poly (ethylene terephthalate) (PET) waste and study of the structure – property relation for the same in polyesteramide coating. The purpose is also not only to just target the polymeric waste but also to study the effect of the structure of monomer obtained from such waste in final coating.
Design/methodology/approach
PET waste was depolymerised using diethanolamine to tetra(2,2-hydroxyethylene) terephthalamide (THETA). Four functional hydroxyl terminated monomers were generated having amide linkage as a structural part. THETA was used for the synthesis of polyesteramide resin along with fatty amide of oil, and concentration of the THETA was varied. The synthesised polyesteramide resin was cured with MF resin and tested for physico-chemical, thermal and anticorrosive properties.
Findings
PET was successfully depolymerised to monomeric level using diethanolamine as a reactive agent. It is observed that as the concentration of THETA increases, the hardness of the coating increases, as aromatic concentration increases in the coating. The amide linkage helps to improve adhesion as well as hydrophobicity because an aliphatic long chain of fatty amide and aromatic linkage of THETA helps in improving anticorrosive properties of the coating.
Practical implications
This method is the useful key to solve the polymeric waste problem. PET can be easily depolymerised using diethanolamine and polyesteramide resin synthesised from it. Hence, waste material can be converted into the coating by reacting it with renewable resources.
Originality/value
To the best of the authors’ knowledge, this is the first study which uses THETA as a monomer for the synthesis of polyesteramide resin and study of its various concentrations on coating properties. The coating is obtained from waste material; hence, polymeric waste issue is also solved, and dependency on the petroleum resources to obtain raw materials for coating is also depleted partially. The study also helps to understand the effect of the structure of monomers on the properties of the coating.

Abstract
The 26th United Nations Climate Change Conference of the Parties (COP26) has reinvigorated the policy focus on sustainable transport. Automated and Connected Transport (ACT) has been featured as a promising technology-based option to aid in meeting the Sustainable Development Goals (SDGs). Despite progress in certain areas of sustainability, there are still a lot of SDGs where limited progress has been observed since the 2015 Paris Agreement, particularly regarding the social pillar of sustainability which is reflected from the user perspective. This chapter will set the scene for this edited volume first by contrasting ACT potential with the SDGs and then by highlighting the requirement to focus more on addressing user needs through ACT. Remarkably, scholars have been increasingly sceptical about the transition to fully automated and connected vehicles, thus it is pertinent to highlight relevant opportunities and risks. Chapter recommendations foster the promotion of a Quadruple Helix approach to operationalise the inclusion of social concerns (e.g. gender balance and equity) in Sustainable Urban Mobility Plans (SUMP) across the world.
