This paper studies how consumers' reported practices related to food, energy use in housing, daily mobility, and tourism are combined and structured. Social practice theories are the main theoretical framework of this research. Data are drawn from a sensitisation campaign run by the WWF-Belgium and the methods developed to attempt to translate the theoretical focus to practices. Results show that both the low number of ‘green’ practices reported and the multiplicity of combinations of practices indicate a rather important compartmentalisation of ‘green’ practices and seem to refute the hypothesis of vast domino effects in these four different areas. In addition, a wider openness to information on environmentally friendlier practices is associated with a larger number of such practices, which raises questions about the design of such campaigns. Finally, there is no conventionalised way of linking practices and commitments taken by the respondents to reduce their environmental impact. A few policy recommendations are derived for sensitisation campaigns that often assume domino effects between ‘green’ practices, and for tools dealing with personal carbon awareness.

Greenhouse gas emissions related to food production in selected countries around the world in 2000, 2007, and 2014 were analyzed in this paper. In recent decades, many studies have suggested that greenhouse gas emissions mostly caused by agricultural production should be reduced. However, a low-carbon agricultural sector often involves a reduction in inputs, which may result in smaller production volumes. Nevertheless, the overarching goal should be to maintain food production at a sufficient level to meet the population's food requirements. Food production is particularly important in the context of the forecasted growth of the world population. In this situation, greenhouse gas emissions per product unit should be regarded as a key indicator that reflects the environmental sustainability level of production processes. Defined as such, environmental sustainability was examined across the entire food production system—referred to as agribusiness. This study calculated the emissions of major greenhouse gases related to food production and compared them to the GDP of agribusiness. The average ratio of the agribusiness carbon footprint to GDP in countries examined was nearly 2 kg of CO 2 equivalent/USD in 2000. This value kept decreasing during the study period, reaching 1.21 in 2014. A decrease in the ratio was recorded despite an increase in agribusiness greenhouse gas emissions, which validated the research hypothesis that an increase in greenhouse gas emissions from agribusiness does not necessarily reflect a decline in the environmental performance of agribusiness production. This is especially true for China and Brazil, whose greenhouse gas emissions related to food production increased considerably in the years examined in this study along with a clear decline in emission levels per unit of agribusiness GDP. This study is innovative, because the literature does not provide any similar calculations for the food production subsystem, especially regarding emission levels per production unit. This approach required the authors to integrate the calculation methods used in agribusiness production with those applicable to agribusiness greenhouse gas emissions. Thus, this study relied on consistent methods developed by the authors to calculate these values. The research adds to existing literature by calculating the carbon footprint for the entire food production system, and it argues that better environmental performance of agribusiness production can be achieved despite higher greenhouse gas emissions.
