Berki-Kiss, D.; Menrad, K. (2022): The role emotions play in consumer intentions to make pro-social purchases in Germany – An augmented theory of planned behavior model. Sustainable Production and Consumption 29, S. 79-89. DOI: 10.1016/j.spc.2021.09.026
Although, sustainable consumption is gaining in relevance for consumers
and retailers in Germany, pro-social consumption is still often
neglected. Therefore, this study investigates factors influencing the
purchase intention of German flower buyers in relation to Fairtrade-cut
roses based on an online survey of 1,201 flower buyers in retail shops
in 2017. As a basic theoretical framework, the Theory of Planned
Behavior (TPB) was utilized and extended with two additional constructs.
The addition of emotions and perceived consumer effectiveness reveals a
strong explanatory power of the model proposed. Data analysis via
partial least square structural equation modeling (PLS-SEM) suggests
that emotions and subjective norm are the two most influential
determinants of intention to purchase Fairtrade roses. However, emotions
also significantly influence all determinants of behavioral intention
introduced to the extended model. The findings of this study can be used
to fine-tune marketing and communication activities related to
pro-social and Fairtrade products.

This study investigated the sustainability challenges and the adoption
of sustainability innovations along the value chain of flowering potted
plants supplying the German market. Data was collected through eighteen
in-depths interviews with chain actors from different stages of the
value chain and analyzed through qualitative content analysis. The
material flow of the value chain begins at the breeding level followed
by the propagation level. Cuttings are produced mostly in African
countries, rooted cuttings and potted plants are cultivated in Europe.
The main environmental challenges include water scarcity, pesticide use
and carbon footprint. Social challenges in Africa include low wages and
difficult working conditions. In Germany, social challenges include
recruitment and retention of employees and product transparency.
Economic challenges include profitability and the need to comply with
standards. Sustainability driven innovations can address some
sustainability challenges. However, their implementation often leads to
increased costs, financial risk and complexity of implementation.
Furthermore, the lack of product transparency prevents the transfer of
sustainability costs to the consumer by offering a sustainable product
for a premium price. Business-to-business standards have generally had a
positive influence on the adoption of sustainability innovations. But
by setting certification as an entry barrier for suppliers, retailers
have become more powerful chain actors.
