The Impact

Food production is a major contributor to environmental damage. More environmentally sustainable foods could incur higher costs for consumers. In this review, we explore whether consumers are willing to pay (WTP) more for foods with environmental sustainability labels (‘ecolabels’). Six electronic databases were searched for experiments on consumers’ willingness to pay for ecolabelled food. Monetary values were converted to Purchasing Power Parity dollars and adjusted for country-specific inflation. Studies were meta-analysed and effect sizes with confidence intervals were calculated for the whole sample and for pre-specified subgroups defined as meat-dairy, seafood, and fruits-vegetables-nuts. Meta-regressions tested the role of label attributes and demographic characteristics on participants’ WTP. Forty-three discrete choice experiments (DCEs) with 41,777 participants were eligible for inclusion. Thirty-five DCEs (n = 35,725) had usable data for the meta-analysis. Participants were willing to pay a premium of 3.79 PPP$/kg (95%CI 2.7, 4.89, p ≤ 0.001) for ecolabelled foods. WTP was higher for organic labels compared to other labels. Women and people with lower levels of education expressed higher WTP. Ecolabels may increase consumers’ willingness to pay more for environmentally sustainable products and could be part of a strategy to encourage a transition to more sustainable diets.

Abstract Background: In order to achieve an environmentally friendly and sustainable energy supply, it is necessary that this goal is supported by society. In different countries worldwide it has been shown that one way consumers want to support the energy transition is by switching to green electricity. However, few people make the leap from their intention to a buying decision. This study explores parameters that influence whether German consumers would hypothetically decide to switch to a green electricity tariff.Methods: A quota-representative online survey including a discrete choice experiment with 371 German private households was conducted in 2016. For the econometric analysis, a generalized multinomial logit model in willingness to pay space was employed, enabling the estimation of WTP values to be as realistic as possible.Results: The results show that consumers’ decision whether or not to make the switch to green energy is mainly influenced by the source of green energy, whether a person can outsource the switching process, and a person’s attitude towards the renewable energy sources levy that currently exist in Germany.Conclusions: The findings indicate that politics should focus on supporting wind and solar energy as German consumers prefer these sources over biogas. As the results suggest, the EEG levy is a reason why consumers have lower WTP for switching to a green tariff. Therefore a switching bonus with a specifically “framed” bonus in the amount of the current EEG levy could be a promising strategy for the increase of green energy tariff acceptance. Furthermore, attention should be given to psychological and behavioral aspects, as the results indicate that these factors influence the consumer’s choice for a green electricity tariff.JEL classifications: C23, C25, Q40, Q50

Green electricity, which comes from renewable sources such as wind, hydro and solar, are well appreciated for their being environment friendly. The advantage of these sources are apparent in part of already natural environment. Moreover, this modern form of electricity also contributes in the poverty alleviation in developing countries, which is one of the sustainable development goals (SDG). The objective of this study is to explore electricity consumers’ willingness to pay for the sustainable energy by employing the contingent valuation method (CVM). The respondents were divided into two broad categories of urban and rural consumers. A total of 400 respondents from urban and 405 respondents from rural areas were selected for this study. The CVM calculated the overall price of green electricity for the improvement of environment through increasing the share of electricity from renewable energy sources. The widely used WTP measure double-bounded dichotomous was utilised to elicit the appropriate value of green electricity from the bid price. The results from the logit regressions showed that the respondents with high income and a higher level of education are willing to pay more for green electricity in both urban and rural models. However, results also revealed that the willingness to pay for green electricity is high in younger people than older people. The mean willingness to pay has found 0.33 cents per kWh in the urban model, while is 0.24 in the rural model. The results provided a guideline to the government to charge an appropriate surcharge from the consumers in order to enhance the share of green electricity in energy mix.

ObjectiveTo determine the cost-effectiveness of selective digestive decontamination (SDD) as compared to selective oropharyngeal decontamination (SOD) in intensive care units (ICUs) with low levels of antimicrobial resistance.DesignPost-hoc analysis of a previously performed individual patient data meta-analysis of two cluster-randomised cross-over trials.Setting24 ICUs in the Netherlands.Participants12 952 ICU patients who were treated with ≥1 dose of SDD (n=6720) or SOD (n=6232).InterventionsSDD versus SOD.Primary and secondary outcome measuresThe incremental cost-effectiveness ratio (ICER; ie, costs to prevent one in-hospital death) was calculated by comparing differences in direct healthcare costs and in-hospital mortality of patients treated with SDD versus SOD. A willingness-to-pay curve was plotted to reflect the probability of cost-effectiveness of SDD for a range of different values of maximum costs per prevented in-hospital death.ResultsThe ICER resulting from the fixed-effect meta-analysis, adjusted for clustering and differences in baseline characteristics, showed that SDD significantly reduced in-hospital mortality (adjusted absolute risk reduction 0.0195, 95% CI 0.0050 to 0.0338) with no difference in costs (adjusted cost difference €62 in favour of SDD, 95% CI –€1079 to €935). Thus, SDD yielded significantly lower in-hospital mortality and comparable costs as compared with SOD. At a willingness-to-pay value of €33 633 per one prevented in-hospital death, SDD had a probability of 90.0% to be cost-effective as compared with SOD.ConclusionIn Dutch ICUs, SDD has a very high probability of cost-effectiveness as compared to SOD. These data support the implementation of SDD in settings with low levels of antimicrobial resistance.
