Abstract

Purpose

This paper analyzed country-wise energy consumption, sources of emissions, and how it gets impacted by their socioeconomic development and provides a framework for integrated climate and development policy.

Design/methodology/approach

An analysis of energy supply, consumption and emissions across developed and developing economies using long-term empirical data.

Findings

The framework provided areas to be focused on reducing emissions during the economic and social development trajectory of nations.

Research limitations/implications

It provides a holistic and integrated picture of the context of emissions that induced global warming and developmental challenges for different types of countries.

Practical implications

All nations must reduce fossil fuel consumption to reduce anthropogenic greenhouse gas (GHG) emissions to keep the planet's temperature rise within 1.5 degrees Celsius compared to the preindustrial period.

Social implications

Sustainable/green technologies might need upfront investment to implement sustainable technologies.

Originality/value

The main contribution of this paper is to provide a long-term integrated perspective on energy demand and supply, emissions, and a framework for the formulation of an integrated climate and development policy.

Abstract

Purpose

Sustainable mobility will be the key to the survival of mankind in the 21st century. Cities with debt-ridden and poorly managed transport systems have to change to the ever-growing demands of the public transport system. The low cost of transport has been a key factor in sustainable development for any city. This study is trying to propose a framework for the selection of sustainable transport in context to an Indian case of NCR Delhi, India.

Design/methodology/approach

The present study has identified eight criteria for the selection of a sustainable transport system. Criteria for selection of sustainable transport are CO2 emissions, cost of fuel, energy efficiency, cost of maintenance, number of accidents, congestion, number of injuries and road noise. Three alternatives of transport considered for this study are state-run bus, pooled car and Shuttl (App-based buses). The analytic hierarchy process (AHP) is used to prioritize the criteria. The study has further illustrated a framework for the selection of sustainable transport based on these criteria.

Findings

It is observed that CO2 emissions are the most important criterion for a sustainable transport system. It is followed by a reduction in congestion and the number of injuries. Three alternatives of transport considered for this study are state-run bus, pooled car and Shuttl (a service provider). Shuttl has been found to be the most sustainable transport system.

Research limitations/implications

AHP is not able to capture the vagueness in decision-making. Therefore, fuzzy AHP can be considered for further detailed analysis as future scope of study in a different context of a sustainable transportation system. Major implications for policymakers and stakeholders are that development of public transport in cities should be done after considering different dimensions of sustainable operations.

Originality/value

The study has proposed a unique framework for the selection of a sustainable transport system by the public based on sustainability criteria. Findings will help policymakers in formulating strategies for developing sustainable transport system.

The purpose of this paper is to analyze the keywords used in peer-reviewed literature on green supply chain management.

Abstract

Purpose

The purpose of this paper is to analyze the keywords used in peer-reviewed literature on green supply chain management.

Design/methodology/approach

To determine the keywords that were used in this area, an analysis of 629 papers was conducted. The papers were identified through searches of 13 keywords on green supply chains. Trends in keyword usage were analyzed in detail focusing on examining variables such as the most frequently used journals/keywords, their frequencies, citation frequency and research contribution from different disciplines/countries.

Findings

A number of different terms have been used for research focused on the environmental impacts of supply chains, including green supply chains, sustainable supply chains, reverse logistics and closed-loop supply chains, among others. The analysis revealed that the intensity of research in this area has more than tripled in the past six years and that the most used keyword was “reverse logistics”. The use of the terms “green supply chains” and “sustainable supply chains” is increasing, and the use of “reverse logistics” is decreasing.

Research limitations/implications

The analysis is limited to 629 papers from the Scopus database during the period of 2007 and 2012.

Originality/value

The paper presents the first systematic analysis of keywords used in the literature on green supply chains. Given the broad array of terms used to refer to research in this area, this is a needed contribution. This work will help researchers in choosing keywords with high frequency and targeting journals for publishing their future work. The paper may also provide a basis for further work on developing consolidated definitions of terms focused on green supply chain management.

Abstract

Purpose

This paper aims to highlight the importance and need to include carbon emissions from international transport in the sourcing decisions of corporate organizations and the calculation of national emissions inventories (NEIs).

Design/methodology/approach

The paper proposes a method of attributing emissions from international transportation in global supply chains and calculating their impact on the economic sustainability of corporate organizations through a carbon price.

Findings

An application of the original model developed in this paper showed that international transport emissions can have an important effect on NEIs. An example of the imports of manufactured items from China and Germany to the USA showed a 3 per cent increase in emissions from manufacturing activities in the USA.

Research limitations/implications

Introducing carbon pricing on international transport emissions is expected to motivate corporate leaders to include emissions from international transport as a factor in their sourcing decisions.

Practical implications

Inclusion of international transport emissions along with the imposition of a carbon tax are designed to act as disincentives to generating emissions from supply chain activities. It is argued that the implementation of the model may provide long-term benefits associated with reduced emissions and a level playing field to organizations which use efficient technologies in manufacturing.

Social implications

It is recognized that the implementation of a carbon tax on international transport emissions may face resistance from several stakeholders, including governments of exporting countries, corporations and customers, due to an increase in cost.

Originality/value

This paper provides an original method to include emissions from international transport in supply chain decisions.
