Behind the scenes of Ikea's environmental sustainability pledge by Patrick Elf

Late last year, Ikea unveiled plans to cut greenhouse gas emissions from its production systems by 80% in absolute terms by 2030 from their levels two years ago. University of Surrey's Patrick Elf provides an in-depth overview of Ikea's Live Lagom project, which provided the basis for its ambitious sustainability commitment.

Late last year, in the run-up to the COP 24 climate policy conference in Katowice, Inter Ikea chief executive Torbjorn Loof announced that he hopes for “a leadership that steps up, sets clear targets and dares to nail a number of commitments without us having all the solutions”.

Facilitating Positive Spillover Effects: New insights from a mixed-methods approach exploring factors enabling people to live more sustainable lifestyles

This paper presents findings of a 1-year longitudinal behaviour change project led by a commercial retailer in the United Kingdom and Ireland to examine behaviour change and potential spillover of pro-environmental behaviour, and how this may be associated with changes in environmental identity and perceptions of ease and affordability as well as perceptions of how participation in the project has helped support behaviour change.

Higher Wages for Sustainable Development?—Employment and Carbon Effects of Paying a Living Wage in Global Apparel Supply Chains

In this paper we explore how paying a living wage in global supply chains might affect employment and carbon emissions:  Sustainable Development Goals 8 and 13. Previous work has advocated using wage increases for poorer workers to increase prices for wealthier consumers, thereby reducing consumption and associated environmental damage.

Social hotspot analysis and trade policy implications of the use of bioelectrochemical systems for resource recovery from wastewater

Bioelectrochemical systems (BESs) have been catalogued as a technological solution to three pressing global challenges: environmental pollution, resource scarcity, and freshwater scarcity. This study explores the social risks along the supply chain of requisite components of BESs for two functionalities: (i) copper recovery from spent lees and (ii) formic acid production via CO2 reduction, based on the UK’s trade policy.

Mathematical modelling of moisture migration in confectionery multi-component food systems

Moisture migration occurring during storage in multicomponent food systems is one of the most common problems facing the food manufacturing industry. An example for such a food system is a mass of ice cream in contact with a wafer. In this work, a dynamic moisture migration model for a confectionery food system consisting of a wafer separated by a moisture barrier from a high water activity component (e.g. ice cream) is developed. The 1D diffusion equation was solved for the barrier and wafer each having different transport properties. The developed model predicts the moisture content of the wafer in different locations throughout the product’s shelf life.
