This article aims to quantify to what extent collaborative strategies are more effective than internal or organization‐level actions to green supply chains. In this regard, the impact of decisions made at different stages of a supply chain in a product's carbon footprint is quantified. Organizational and product carbon footprints are calculated using the Compound Method Based on Financial Accounts (MC3). The results underline that concentrating reduction efforts in some stages of the supply chain is more effective than implementing individual actions by the participants. Collaboration among the participants is needed to decide what practices are implemented, at what stage they are needed and how they are to be implemented. This article adds to the literature on supply chains and sustainability. Previous research suggests that collaborative strategies have great potential for reducing the carbon footprint of products, while indicating the need for empirical research to support this statement.

Green corridors are a European concept denoting long-distance freight transport corridors where advanced technology and co-modality are used to achieve energy efficiency and reduce environmental impact. Green corridors consider all types of agents acting in the door-to-door co-modality chains, including ports. Carbon footprints (CF) provide companies, customers and other agents with information related to greenhouse gas (GHG) emissions from the supply chain of products, identifying key points, potential risks and opportunities for improvement. Its application in both the logistic networks and all modes of transport would allow for the creation of green corridors and sustainable motorways of the sea. This paper describes the method which is composed of financial accounts (MC3) used to estimate the CF of a port. It shows the effects of the method on the Port of Gijo´n (PAG), which steers the existing Gijo´n/Nantes/Saint-Nazaire motorway of the sea. The extension of the system to all nodes of the shipping line and other transport modes will lead in the long run to a carbon-neutral green corridor. Our findings show the importance of looking at indirect emissions in order to become a carbon neutral port.

Strengths-Weaknesses-Opportunities-Threats Analysis of Carbon Footprint Indicator and Derived Recommendations ABSTRACTDemand for a low carbon footprint may be a key factor in stimulating innovation, while prompting politicians to promote sustainable consumption. However, the variety of methodological approaches and techniques used to quantify life-cycle emissions prevents their successful and widespread implementation. This study aims to offer recommendations for researchers, policymakers and practitioners seeking to achieve a more consistent approach for carbon footprint analysis. This assessment is made on the basis of a comprehensive Strengths-Weaknesses-Opportunities-Threats or SWOT Analysis of the carbon footprint indicator. It is carried out bringing together the collective experience from the Carbonfeel Project following the Delphi technique principles. The results include the detailed SWOT Analysis from which specific recommendations to cope with the threats and the weaknesses are identified. In particular, results highlight the importance of the integrated approach to combine organizational and product carbon footprinting in order to achieve a more standardized and consistent approach. These recommendations can therefore serve to pave the way for the development of new, specific and highly-detailed guidelines.
