ABSTRACT

Corporations increasingly subscribe to the principles of corporate sustainability, which is generally de­scribed as the integration ofeconomic, environmental, and social dimensions. As sustainability presents a new source of ideas and visions leading to new business opportunities and competitive advantage, the role of Sustainability-Oriented Innovation (SOI) is ever more emphasized. However, developing products under the paradigm of SOI is risky: both the product’s market success and (non-economic) sustainability effects are uncertain. Product-Service System (PSS) - i. e. a combination of products and services -constitutes a significant approach to overcome some of the limitations of SOI and, addition­ally, can spur the diffusion of SOI. In this chapter, we use an exploratory research strategy to further investigate the links between SOI and PSS. We present a case study on off-grid lighting in Kenya and analyze the sustainability effects on the product and PSS level. The complexity of SOI and the sustain­ability potentials of PSS are illustrated. Moreover, we also emphasize the role of a joint achievement of sustainability-oriented product innovations and PSS innovations.

INTRODUCTION

For the last decade, the prevailing form of doing business has been increasingly challenged by a number of problems such as climate change, environmental degradation, and social inequali­ties. These challenges culminate in the view that to only focus on economic aspects of business is ever more difficult or even impossible as it is es­sentially unsustainable (Hart & Milstein, 2003).

From a business perspective, corporate sustainability seeks to address these issues by transcending the conventional responsibilities of businesses (i. e. to make profits) to also include non-economic aspects such as ecological and social responsibilities (Sharma, 2002; Schaltegger & Burritt, 2005). Scholars have lately emphasized to put sustainability at the core of the corpora­tion, i. e. its products and services (Hart, 1997; Schaltegger & Wagner, 2010). New regulations, but also raising consumer demand for socially and environmental benign products drive the need for more sustainable products and services. The no­tion of sustainability-oriented innovations (SOI) thus embraces concepts, criteria, and processes to develop more sustainable products and services (Hansen et al., 2009).

One important lever for SOI is the concept of product-service systems (PSS) or servitization (Baines et al., 2007; Mont 2001, 2004; Hansen et al., 2009). Generally, PSS approach represents a spectrum between pure products and pure services (Baines et al., 2007; Pawar et al., 2009). PSS where the manufacturer remains with the ownership of the products are especially interesting. In this case, PSS follows the idea that the environmental burden is dramatically decreased when switching from selling products to providing solutions through product-service combinations. In contrast to mid to long-term leasing and performance contracting in the business to business context (Williams,

2006) , this chapter focuses on systems of shared use in business to consumer markets.

Current empirical studies on shared use in business to consumer markets are usually case studies (Baines et al., 2007) and focus on such as car sharing (Huwer, 2004; Engelhardt et al.,

2003) , ride sharing (Hansen et al., 2010), and on washing machine and power tools service centers (Mont, 2004). Besides few others (Devisscher & Mont, 2008; Manzini & Vezzoli, 2000), existing cases predominantly focus on developed nations. The cases often evaluate the sustainability impacts of PSS (Pawar et al., 2009, Devisscher & Mont,

2008) . PSS is said to be a concept that “aims to improve overall system efficiency, along with improving efficiency of each system element” (Mont, 2001, 13). However, most ofthe case stud­ies are limited to studies where existing products and technologies are integrated into a PSS, i. e. the innovation considers only the servitization of the unchanged product or technology. There is virtually no research on cases where the prod­uct innovation joins the introduction of the PSS. Our research question is thus twofold: (1) how can the mechanism of PSS help to introduce a sustainability-oriented product innovation? (2) Which sustainability effects materialize on the product level, which ones at the service level?

This chapter addresses this gap with a case study approach (Yin, 2003) about a multina­tional corporation based in Germany that offers a product-service system in a developing nation. By concurrently addressing economic, envi­ronmental, as well as social impacts, the case highlights the multi-dimensionality of SOIs. We furthermore emphasize the importance of PSS as being an innovation enabler on a (technological) product level and therefore underline the impor­tance of product-service offers in the context of sustainability.

The remainder of this chapter is structured as follows: first, a literature review introduces the concepts of SOI, life-cycle assessments, and PSS. Building on this framework, a case study on off-grid lighting in Kenya is presented and its sustainability effects are analyzed. The results and implications of the case study are then discussed and future research directions are given.

BACKGROUND Sustainability-Oriented Innovation (SOI)

There is wide agreement that the challenges of sustainability offer significant potentialfor prod­uct and service innovations and related business opportunities. Two arguments support this view. First, new social and environmental regulations and laws increase the pressure for innovativeness (“regulatory push”) (Fichter, 2006; Hockerts, 2008; Preuss, 2007). Second, sustainability pres­ents a new source of ideas and visions leading to new business opportunities through new markets and customer segments (“market pull” or “vision pull”) (Hart, 1997; Day, 1998). Based on these insights, the importance of SOIs has generally been acknowledged (e. g. Hansen et al., 2009; Hart, 1997; Schaltegger & Wagner, 2010). How­ever, recent studies show that only a minority of businesses consider sustainability as a source of innovation (Hockerts & Morsing, 2008).

The reluctance in advancing SOIs can argu­ably be attributed to the high risks involved in this kind of innovation (Hall, 2002). These risks include not only the product’s economic success (Cooper, 2001), but also the direction of envi­ronmental and social sustainability effects of in­novations, i. e. whether they contribute positively or negatively to sustainability. The latter type of risk is also termed directional risk (Paech, 2005). For instance, environmental innovations can lead to negative societal impacts, i. e. to a problem of “eco justice ” (Schaltegger & Burritt, 2005), as the case ofbio-fuels demonstrates (Kolsch & Saling, 2008; Rennings & Zwick, 2002). On the other hand, conventional innovation proj ects sometimes result in innovations with positive sustainability effects (Fichter & Arnold, 2003). Due to the multi-dimensionality of sustainability targets (social, environmental, and economic targets) and the dispersion of innovation sustainability effects, the assessment of innovations with respect to sustainability is considered highly complex (Fichter, 2005).

Beyond the triple bottom line reflecting eco­nomic, social, and environmental considerations (Elkington, 1998), also referred to as the target dimension of innovation, two other dimensions - life-cycle and innovation type- are important for assessing sustainability effects of product in­novations. Both dimensions are addressed in the subsequent sections.
