Purpose

This paper aims to elucidate what concepts of encroachment in business-to-consumer markets explain the market share increase of companies with sustainability value propositions. It documents the encroachment field, analyses the practice of ten companies and proposes and defines the additional concept of transparency encroachment.

Design/methodology/approach

Semi-structured interviews were conducted with representatives of companies with an increase in customers and market share due to their sustainability value proposition. These were supplemented with secondary data, like documented interviews, sustainability reports and reports on market development. The interview transcripts and secondary data notes were coded using template analysis.

Findings

As the literature on encroachment assumes that new value propositions take away market share from incumbents due to advantages for customers, it is questionable whether it can explain how value propositions with advantages for society as a whole can encroach markets. The results of this study show that the dominant forms of encroachment in the current literature – high-end encroachment, low-end encroachment and business model encroachment – can only partly explain encroachment through sustainability value propositions. An additional encroachment form is identified: transparency encroachment.

Research limitations/implications

This research adds greater clarity to what companies do when they encroach markets with sustainability value propositions. Furthermore, the pattern of transparency encroachment is discussed to define the common aspects of this concept and to argue why these aspects are needed for encroachment. It implies that marketing activities should start from the perception that customers are allies – and not kings – in the development toward higher levels of sustainability.

Practical implications

The paper offers practical implications insofar as it deconstructs three aspects of transparency encroachment that are enacted by companies. Customer awareness, unique experience and customer contribution are all needed to enact transparency encroachment. It is argued that other companies introducing sustainability value propositions to encroach markets should find their own application of these three aspects to create the potential for successful encroachment.

Social implications

Because of the focus on sustainability aspects of value propositions, this study generates knowledge about the marketing and encroachment of products with a relatively positive impact on society. Adoption of the identified concept of transparency encroachment contributes to sustainable development.

Originality/value

To date, there has been very little marketing research that explores the role of sustainability value propositions in the encroachment of markets. Nonetheless, nowadays customers seem to look beyond their own benefits and are increasingly demanding a new approach that builds upon the sustainability aspects of products. This research adds greater clarity to encroachment through sustainability value propositions.
