Purchasing's contribution to supply chain emission reduction

Does environmental purchasing and supplier management (EPSM) help to reduce greenhouse gas (GHG) emissions in the supply chain and, thereby, mitigate climate change? And, if so, under which conditions? Taking these two questions as a starting point, we hypothesize that heightened environmental protection efforts targeting the upstream value chain should lead to a reduction of greenhouse gas emissions in the buying companies' supply chain. We continue to delineate three contingency factors that might affect the relationship between EPSM and supply chain GHG emissions: The power of the buying firm over supply chain partners, prior experience in EPSM, and materiality of environmental supply chain management in a certain industry. We collect longitudinal data from 260 companies and analyze them using hybrid panel data analysis. We find that the increase of EPSM leads to a significant reduction of the GHG emission intensity of buying firms’ supply chains and that this reduction is stronger for companies operating in industries where emission management is more material.     

Identifying environmentally important supply chain clusters in the automobile industry

In this paper, we develop a new approach that combines the spectral clustering method and input–output analysis to detect environmentally important supply chain clusters. The newly developed method was applied to automobile manufacturing in Japan, and major clusters with high energy intensities in the automobile supply chain were identified. This paper proposes that the car manufacturers will be able to regularly publish their life-cycle assessment reports with a focus on the indirect energy consumptions within the critical supply chains and request key auto-part manufacturers in the cluster to reduce the indirect consumptions through the relevant supply chain engagement.     

The raw material basis of global value chains: allocating environmental responsibility based on value generation

A new approach to allocate environmental responsibility, the ‘value added-based responsibility’ allocation, is presented in this article. This metric allocates total environmental pressures occurring along an international supply chain to the participating sectors and countries according to the share of value added they generate within that specific supply chain. We show that – due to their position in global value chains – certain sectors (e.g. services) and countries (e.g. Germany) receive significantly greater responsibility compared to other allocation approaches. This adds a new perspective to the discussions concerning a fair distribution of mitigation costs among nations, companies and consumers.

Green supply chain management in the automotive industry: A study in Brazil

The auto industry is experiencing a time of restlessness, which stems from several elements that currently threaten the stability and status quo of its supply chains. Among these elements are autonomous driving, connectivity, electrification, and trip sharing that has led to new forms of mobility. In this context, this article presents the results of a research, which had three main objectives: (1) to identify the green supply chain management (GSCM) practices most commonly implemented in all industrial sectors worldwide, (2) to evaluate how these practices are considered by professionals in the automotive industry and by researchers working on the subject in Brazil, and (3) to identify and evaluate which practices are most widely adopted within these companies and/or supply chains and influence their environmental performance. The research method combined a qualitative research step (Delphi) with another quantitative one (survey). The results show that most of the reality of the automotive industry in Brazil is in line with studies on GSCM practices worldwide, but some specific findings have also been identified and discussed.     

Efficiency meets accountability: Performance implications of supply chain configuration, control, and capabilities

The public increasingly holds firms accountable for social and environmental outcomes, such as product toxicity problems and human rights violations, throughout their global supply chains. How can companies improve the social and environmental performance within their supply chains, particularly as other competitive pressures, such as cost and quality, continue to escalate? Starting from an efficient versus responsive supply chain framework, we develop an integrative model that blends together elements of supply chain configuration, stakeholder management, and capability development. Specifically, we spotlight the dimensions of control and accountability that collectively determine stakeholder exposure, and show how this new construct affects the linkages between supply chain capabilities, configuration, and performance. In particular, this analysis reveals that the nature of stakeholder exposure determines how social/environmental technical and relational capabilities impact social and environmental outcomes. We conclude with implications for research and practice, discussing how current supply chain theories must be extended to incorporate external stakeholders, to clarify strategies and identify potential pitfalls, and to better predict performance outcomes.     

Corporate climate-related voluntary disclosures: Does potential greenwash exist among Australian high emitters reports?

This study examines the issue of greenwashing among corporate high emitters subject to government scrutiny. To do so, we investigate the relationship between the actual environmental performance, measured as carbon emissions, of companies subject to the Australian National Greenhouse Energy Reporting Act 2007 (NGER) and their climate-related voluntary disclosures. To measure climate-related disclosure, we construct a climate-related disclosure index based on four prominent frameworks and score corporate report content against that Index. Using a sample of 150 companies with NGER emissions data for Years 2016 and 2017, a period that precedes the issuance of recommendations for disclosure by the Task Force on Climate-Related Financial Disclosure (TCFD), our regression results show a disappointingly low level of climate-related disclosure by most companies. We also find a negative relationship between climate-related disclosure and 1-year lagged environmental performance among companies exhibiting a year-on-year rise in carbon emissions. That is, our findings provide evidence of potential greenwashing by poor environmental performers, presumably to change negative perceptions by stakeholders, as predicted by socio-political theories. In contrast, we find no evidence of greenwashing among companies experiencing a year-on-year decrease in emissions.     

Logistics optimization through a social approach for food distribution

The management of supply chains is becoming more important in economic and social environments. Currently, the social sustainability is a factor that must be considered to design governmental strategies and policies. The objective of this research paper was to show, with a case study an approach to optimize distribution and delivery logistics of food in a social assistance program of school breakfast using mathematical models that include transportation distance, optimal locations, and vehicle routing through different clusters. By using qualitative variables like poverty levels, food insecurity and social exclusion, different clustering methods are proposed with the purpose of identifying the common characteristics in the studied population; and at the same time, reducing the distribution complexity. The results show an efficient approach to design a supply chain that includes economic and social factors. The new model developed in this paper can be used to plan social assistance governmental programs, to identify the specific needs and characteristics of the beneficiaries, minimizing the total cost of the distribution network logistics when delivering food for school meals.     

Balancing priorities: Decision-making in sustainable supply chain management

The need for environmental protection and increasing demands for natural resources are forcing companies to reconsider their business models and restructure their supply chain operations. Scholars and proactive companies have begun to create more sustainable supply chains. What has not been fully addressed is how organizations deal with short-term pressures to remain economically viable while implementing these newly modeled supply chains. In this study, we use theory-building through case studies to answer the question: how do organizations balance short-term profitability and long-term environmental sustainability when making supply chain decisions under conditions of uncertainty? We present five sets of propositions that explain how exemplars in green supply chain management make decisions and balance short and long term objectives. We also identify four environmental postures that help explain the decisions organizations make when dealing with strategic trade-offs among the economic, environmental and social elements of the triple-bottom-line.     

Determinants of monetary penalties for environmental violations

This research investigates the likely determinants of monetary penalties for poor environmental performance. We retrieve data from Bloomberg on the monetary penalties imposed on companies in the European Union (EU) found to have performed poorly in corporate social responsibility (CSR), and particularly in the environmental aspects of CSR. Our primary findings reveal that firms with high levels of greenhouse gas and hazardous waste emissions are more likely to receive monetary penalties. On the other hand, firms that invest in green supply chain practices and disclose environment‐related matters avoid monetary penalties more. We also find that firms having executive compensation linked with environmental compliance face more monetary penalties. This finding adds a new dimension to the voluminous research on executive compensation that has investigated primarily the effects of cash and stock option‐based compensation schemes on pay–performance sensitivities.

Assessing the Comprehensiveness of Supply Chain Environmental Strategies

As environmental awareness grows, firms are expected to expand the scope of their environmental strategies beyond organisational boundaries and to address more comprehensively environmental issues in their supply chains and product life cycles. Drawing on different literature streams, international standards and corporate disclosure, this paper presents a conceptual framework for the quantitative assessment of the comprehensiveness of firms' environmental strategies. This framework allows us to capture: (i) the environmental inputs and outputs addressed, (ii) the firm versus supply chain orientation of environmental strategies, and (iii) the environmental management practices adopted by companies. We illustrate the application of this framework with a content analysis of corporate sustainability reports for a cross‐sectoral sample of sustainability leaders. Our results indicate that there is a need for greater specificity in environmental reporting and that, overall, companies remain firm‐oriented. It is also observed that supply chain orientation can generally be associated with stakeholder pressure. Copyright © 2012 John Wiley & Sons, Ltd and ERP Environment.     

Sustainable supply chain management and partner engagement to manage climate change information

Climate change poses significant new risks and challenges for businesses and their supply chains. Additionally, in many sectors, Scope 3 indirect greenhouse gas emissions resulting from the sourcing and distribution of goods and services are larger than firms' own carbon footprints. Here we study how firms engage their key stakeholders in their supply chains in obtaining, processing, and transferring relevant climate change‐related information designed to overcome information asymmetry and drive sustainable development. Grounded in organisational information‐processing theory (OIPT), we draw on data from the Carbon Disclosure Project's Climate Change Supply Chain initiative for a qualitative content analysis of a large sample of global firms. Consistent with OIPT, we find that although firms primarily engage their supply chain partners in a variety of ways to reduce information uncertainty around indirect emissions data, effectively interpreting and managing broader sustainability information equivocality becomes a growing priority. Our findings further suggest that firms engage suppliers, customers, and other supply chain partners through basic, transactional, and collaborative types of engagement. We contribute to literatures on interorganisational information processing and sustainable supply chain management by providing a more detailed understanding of how firms engage supply chain partners in the context of climate change.     

Mitigating climate change – how do corporate strategies differ?

Many companies are facing increasing pressure by governments, shareholders and other stakeholders to reduce their CO₂ emissions in order to mitigate climate change. The importance of managing CO₂ emissions and crafting adequate CO₂ strategies has increased for those companies affected. We present a framework that conceptualizes a company's CO₂ strategy as the focus on one or a combination of several strategic objectives: CO₂ compensation, CO₂ reduction and carbon independence. In order to investigate the CO₂ strategies of a worldwide sample of 91 electricity producers we perform a content analysis of their answers to the Carbon Disclosure Project (CDP). We demonstrate the measures the companies take to manage their emissions, the CO₂ strategies they adopt and antecedents that influence these strategies. We find that half of the companies take parallel emission management measures that aim at all three strategic objectives, while the other half pursue selected objectives only. We also find that companies with different CO₂ strategies significantly differ in terms of regional affiliation, company size and absolute amount of CO₂ emissions, while we could not identify a significant difference in relative CO₂ emissions.

Sustainable Development in Supply Chain Management: The Role of Organizational Learning for Policy Implementation

Implementing sustainable policies in supply chains is a significant challenge for businesses. Recent evidence has shown that failure to manage supply chains responsibly can have significant impacts on firms' reputation and financial performance. In this paper, we develop a conceptual framework, which focuses on organizational learning, and outline specific channels through which firms can generate learning processes and build appropriate capabilities to successfully implement social and environmental supply chain policies. Drawing on 57 in‐depth interviews from a cross‐sectional sample of seven UK and nine German companies, we empirically assess our conceptual framework in accordance with a grounded, in‐depth case study analysis approach. We find compelling evidence to suggest that organizational learning is an important factor for a successful implementation of sustainable supply chain management. Organizational learning is often established as a result of training, knowledge acquisition, stakeholder engagement and collaboration between intra‐organizational and inter‐organizational partners, including suppliers and NGOs. Nonetheless, our results also emphasize that firms often have few systematic processes through which organizational learning is developed, and that such learning processes are often ad hoc at best, which in turn has significant implications for the responsible supply chain practices.

Intra‐Sectoral Differences in Climate Change Strategies: Evidence from the Global Automotive Industry

Companies are increasingly challenged for action on climate change. Most studies on business responses to climate change focus on cross‐sector comparisons and neglect intra‐sectoral dynamics. This paper investigates the influence of supply chain position and regional affiliation on climate change strategies within a particular industry. We present a generic framework integrating both market and non‐market responses to climate change. We argue that climate change strategies comprise several corporate activities that have different foci of interaction and four main objectives: governance, innovation, compensation and legitimation. Using a global sample of 116 automotive companies, we conduct a cluster analysis and identify four types of strategy. We find that the sophistication of automobile manufacturers' strategies significantly differs from that of suppliers. Regional affiliation and firm size prove to be determinants of the strategy type pursued. We cannot find evidence for a relationship between financial performance and a company's strategic approach to climate change. © 2017 The Authors.

CALCULATING ENERGY-RELATED CO2 EMISSIONS EMBODIED IN INTERNATIONAL TRADE USING A GLOBAL INPUT–OUTPUT MODEL

The Global Resource Accounting Model (GRAM) is an environmentally-extended multi-regional input–output model, covering 48 sectors in 53 countries and two regions. Next to CO₂ emissions, GRAM also includes different resource categories. Using GRAM, we are able to estimate the amount of carbon emissions embodied in international trade for each year between 1995 and 2005. These results include all origins and destinations of emissions, so that emissions can be allocated to countries consuming the products that embody these emissions. Net-CO₂ imports of OECD countries increased by 80% between 1995 and 2005. These findings become particularly relevant, as the externalisation of environmental burden through international trade might be an effective strategy for industrialised countries to maintain high environmental quality within their own borders, while externalising the negative environmental consequences of their consumption processes to other parts of the world. This paper focuses on the methodological aspects and data requirements of the model, and shows results for selected countries and aggregated regions.     

Green bonds as a tool against climate change?

Although green bonds are becoming increasingly popular in the corporate finance practice, little is known about their implications and effectiveness in terms of issuers' environmental engagement. With the use of matched bond-issuer data, we test whether green bond issues are associated to a reduction in total and direct (Scope 1) emissions of nonfinancial companies. We find that, compared with conventional bond issuers with similar financial characteristics and environmental ratings, green issuers display a decrease in the carbon intensity of their assets after borrowing on the green segment. The decrease in emissions is more pronounced, significant and long-lasting when we exclude green bonds with refinancing purposes, which is consistent with an increase in the volume of climate-friendly activities due to new projects. We also find a larger reduction in emissions in case of green bonds that have external review, as well as those issued after the Paris Agreement.     

Integrating Strategic Carbon Management into Formal Evaluation of Environmental Supplier Development Programs

Increasing global environmental pressures from regulators, markets and communities have caused focal companies in supply chains to recognize the significance of environmentally conscious management. Greener supply chains are part of this recognition. Environmental supplier development is a valuable and viable strategy for greening supply chains. However, low carbon management is rarely explored in supplier development. Further, formal tools and models for focal companies to evaluate environmental supplier development programs (ESDPs) considering low carbon management and their effect on supplier performance improvement are limited. To help address these gaps in the literature, this paper proposes a portfolio evaluation model for ESDPs that consider three types of supplier performance: traditional operational factors, traditional environmental factors and low carbon management factors. This model applies the fuzzy scoring method to measure the effect of ESDPs on supplier performance, and uses fuzzy DEMATEL to examine the cause–effect interrelationships among the ESDPs. Subsequently, a real world example is used to demonstrate the application of the portfolio model and provide insights into environmental supplier development evaluation, followed by discussions of case application results. This paper concludes with directions for further research. Copyright © 2014 John Wiley & Sons, Ltd and ERP Environment

Customer pressure and innovativeness: Their role in sustainable supply chain management

This work investigates how sustainable supply chain management develops within a company and evolves from internal to external practices. Specifically, the relationships among sustainable process management (internal practices), sustainable supply management (external practices), customer pressure and innovativeness are elaborated in a conceptual model, which is tested using a survey approach. Partial least squares (PLS) methodology is applied to data collected from a sample of 77 Italian manufacturing firms. Our results highlight that customer pressure and innovativeness positively and significantly affect SPM. We also observe that SPM fully mediates the relationships between such factors and SSM. Finally, innovativeness negatively and significantly moderates the effect customer pressure has on SPM. This study is relevant because it shows what driving and enabling factors influence the development of SSM, providing guidance for companies that wish to achieve further social and environmental improvements in their supply chains.
