Eco-labels, Trade and Protectionism

Eco-labels are suspected to serve protectionist purposes. We analyze the choice between an environmental standard and a voluntary eco-label scheme in a partial trade model with one domestic firm and one foreign firm. The environmental standard will only apply to the domestic firm, while both firms can adopt the eco-label. Pollution is production related, and domestic consumers demand products that are produced in an “environmentally friendly” way. Our results show that it may be optimal for the domestic government to introduce an eco-label and get both firms to adopt the label, instead of setting an environmental standard. However, to what extent this policy serves protectionist purposes is ambiguous. In particular, if the willingness to pay for green products is sufficient to cover the pollution abatement costs of the foreign firm, foreign firm profit will increase while domestic firm profit will decrease compared to the outcome with a domestic environmental standard. On the other hand, if the willingness to pay for green products is insufficient, the foreign firm would be better off with a domestic environmental standard.     

Consumer confusion over the profusion of eco-labels: Lessons from a double differentiation model

How are eco-label strategies affected by consumer confusion arising from the profusion of eco-labels? This article provides a theoretical insight into this issue using a double differentiation framework. We assume that consumers perceive a label as a sign of quality compared to an unlabeled product, but that they cannot fully assess the environmental quality associated with each label and only see each label as a particular variety of a similar product. We analyze the pricing strategies of three firms, each one providing one product: a labeled product, with high or medium environmental quality, according to the eco-label, or an unlabeled product. We infer lessons for eco-labeling policies, according to the identity of the certifying organization: the regulator, an NGO or the firms. We show that the firm supplying the eco-labeled product with a high environmental quality is weakened by consumer confusion while the firm selling the unlabeled product suffers from strict labeling standards, to the benefit of the firm providing the labeled product with a lower environmental quality, which gains a competitive advantage. Most labeling policies consist of harmonizing labeling criteria, but only certification by a third party, the regulator or a NGO, guarantees the high environmental quality of labeled products, whereas certification by firms leads to a uniform undemanding standard. However, when both labels are provided by two different certifiers, including a firm, harmonization of environmental standards does not occur and the NGO's or regulator's eco-labeling standard will be much more stringent than the firm's one, preventing NGO's or public eco-labeling policy to significantly enhance quality of the environment and welfare.     

Lead markets and regulation: a framework for analyzing the international diffusion of environmental innovations

Environmental regulations are often intended to stimulate the generation and adoption of eco-efficient innovations. An important argument in the public debate is also the creation of new markets for environmentally benign products, processes and services in other countries and the generation, as a result, of export opportunities for the pioneering country (lead markets). Research on lead markets has not, however, focused on environmental innovations to date. We therefore extend the lead market model to environmental innovations and take particular account of the peculiarities of such innovations, in particular, the public good character of environmental benefits and the role of regulations. This approach is applied to two case studies: wind energy and fuel-efficient passenger cars. In both cases, the innovation was initially adopted in one country. Other countries subsequently adopted the same innovation design favored by the lead market which, in turn, developed into a large exporter in the wind generation and car industries, respectively. We discuss the regulations employed and the reasons for the international success of the innovations induced by them. Our findings demonstrate that when supported by global demand or regulatory trends, strict regulation results in the creation of lead markets. Finally, we provide recommendations on how our model could be used for further research and in the development of a coordinated environmental and innovation policy.     

Environment and Food Safety in Agriculture: Are Labels Efficient?

In this article, we try to elicit whether an information on food safety is consistent with a more environmental‐friendly agriculture. As the policy makers generally intervene to limit negative externalities in agriculture on the supply side, is a labelling policy an efficient way to reduce pollution levels in this sector? The intuitive reason of a food safety label rests on the fact that consumers seem to be more concerned with information on food safety aspects than on environmental ones. In a vertical differentiation model, we analyse the impacts of labels mentioning food safety and environmental aspects, on firms' profits, consumers' surplus and pollution levels. Given our main assumption that food safety and environmental consequences are directly linked, our principal results show that a labelling policy on food safety can be efficient from an environmental point of view, depending on the initial healthy products proportion in the market. Another result is based on the fact that a label policy can reduce consumer's surplus.     

What labelling policy for consumer choice? The case of genetically modified food in Canada and Europe

Abstract. Faced with divergent opinions among consumers on the use of genetically modified (GM) foods, Canada has adopted a voluntary labelling approach for non‐GM foods, whereas the European Union has a mandatory labelling policy for GM foods. Interestingly, both labelling systems have resulted in very little, if any, additional consumer choice. Using an analytical model, we show that the coexistence of GM and non‐GM products at the retail level depends on the labelling policy, consumer perceptions, and the type of product. Although voluntary labelling tends to favour the use of GM products, it is more likely to provide consumer choice.

Consumer support for environmental policies: An application to purchases of green cars

This paper focuses on how consumer motivation can be tapped in order to encourage the adoption of cleaner technologies. Consumers are heterogeneous — they may be guided by intrinsic motivation or extrinsic motivation. While information provision policies (such as the energy label for cars) may be effective in encouraging certain consumers to adopt green cars, financial incentive schemes (such as subsidies or fines) may be more persuasive for extrinsically-motivated consumers. We develop a dynamic theory of adoption of environmental innovations, in which information-provision policies are followed by financial incentives (first ‘carrot’, then ‘stick’ incentives). Analysis of a survey dataset of Swiss households observes considerable heterogeneity in terms of support of information-provision or financial incentive policies, in line with our conjectures. Our results will be of particular interest to policymakers interested in guiding consumers towards cleaner technologies.     

Public willingness to pay for endocrine disrupting chemicals-free labelling policy in Korea

As public interest in health and safety grows, endocrine disrupting chemicals (EDC) have become an inevitable problem in society. One way to reduce the social cost of exposure to EDC is to grant a label certification to eco-friendly products that do not release EDC. The Korean government is considering introducing an EDC-free labelling policy. Therefore, our article tries to examine the public willingness to pay (WTP) for implementing the EDC-free labelling policy in Korea. For this purpose, a contingent valuation survey of 1000 Korean consumers was conducted in 2016. We used a one-and-one-half-bounded dichotomous choice question to elicit the WTP responses from the respondents. The mean of household WTP for the EDC-free labelling policy implementation is estimated to be KRW 2266 (USD 2.05) per year. When we expand the value to the whole country, it amounts to KRW 42.9 billion (USD 38.8 million) per year. These values are statistically meaningful at the 1% level and imply that the EDC-free labelling policy contributes to households’ utility and should be implemented immediately.

Eco-Labeling and Market Equilibria with Noisy Certification Tests

An intriguing alternative to traditional methods for regulating externalities is the provision of information about firms’ environmental attributes. An increasingly important example of this approach is “eco-labeling,” where a third party certifies firms’ products. Such schemes are currently used in a variety of countries. This paper investigates the equilibria that may occur with eco-labeling, and the attendant welfare effects. I model certification as a noisy test, subject to both type I and type II errors, but where green firms more likely to pass than brown firms. While it commonly leads to an increase in the fraction of green units in the market, the introduction of an eco-label can either increase or decrease welfare.     

A Micro-Econometric Analysis of Determinants of Unsustainable Consumption in The Netherlands

Recently, much attention has been given to the notion of `sustainable consumption'. Whereas environmental economics traditionally has focused environmental policy analysis on producers, this new notion broadens the perspective to include environmental policies aimed at directly influencing consumer decisions regarding buying, using, and recycling products. This could suggest policies that link not only to price incentives, but also and especially to persuasive instruments, such as education and information provision. These policies might take into account certain characteristics of households, such as lifestyle and family size. This article presents a first econometric analysis of consumption in the context of environmental sustainability. Relationships between different types of household expenditures and a range of household characteristics are assessed, based on a large micro data set of households for the Netherlands. Use is made of various demand models and econometric techniques to adequately address theoretical and technical issues involved. The article ends with a discussion of the implications of the results for environmental policy directed at stimulating sustainable consumption.     

Environmental Consequences of Rising Energy Use in China*

China is already the world's third largest energy producer and second largest energy consumer accounting for 10 percent of global energy use. This share is expected to rise to 15 percent by 2025. Energy use in China has important environmental consequences which are explored in this paper. A range of policy options are also discussed. It is argued that each major environmental issue requires a policy response that is a mix of direct government intervention as well as market based incentives. In coming decades, the choices made by China of how to tackle the environmental consequences of expanding energy use will have important implications for China, Asia and the world.     

Pass-through and Export Prices: an empirical test for the leading European countries

The paper presents an empirical investigation of the extent to which exchange rate movements affect export prices in the leading European countries. By extending the model proposed by Kasa (1992) to a context of monopolistic competition, an export price equation has been derived that allows us to clearly identify the effects of nominal exchange rate movements on the exporters' profit margins and therefore on his prices. This equation has then been estimated with reference to five different products (beer, car tyres, truck tyres, aluminium foil and cars) and six markets (United States, Germany, France, Italy, United Kingdom and Spain). The results show that the pass-through is more likely to occur and larger in absolute value for the less differentiated products, for which markets can plausibly be assumed to be more competitive. In line with previous empirical findings, the German and US markets are the ones in which it is most difficult for exporters to modify their prices expressed in local currency.     

Business incentives for sustainability: a property rights approach

Public and private demands for sustainable development put pressure on firms to develop strategies that include environmental concerns. Environmental effects from products often appear as externalities, outside the legal boundary of the producing company. These companies often possess the best competence to optimise the total life cycle environmental performance of its products. They are, however, neither obliged nor stimulated enough by policy incentives to do so from a sustainable development perspective. The policy instruments used today are mostly of a control-and-demand type, i.e. they do not create sufficient incentives to go further than hedging over set requirements. Environmental concerns and tightened environmental policy parameters have mostly been associated with the notion of additional costs and thus a restriction on economic performance. However, since the mid 1990s, several papers have called for corporate win–win situations as well as instruments giving up-stream incentives for change, but not enough abatement of environmental impacts has emerged in reality. Perhaps this is due to the lack of proper connection between economic theory on the one hand, and incentive advocating articles and instruments on the other. We propose a concept for trading of product life cycle (PLC) emission rights, based on property rights and transaction cost theories considering the problem with asymmetric information over the value chain. The initial financial impacts from such PLC instruments are shown to be significant for the system provider, since emissions—and resource use—become production costs. This provides economic incentives to take an increased responsibility for information flow as well as initiatives for product innovations.     

Socio-Political Evaluation of Energy Deployment (SPEED): An integrated research framework analyzing energy technology deployment

Stabilizing atmospheric concentrations of greenhouse gases to reduce the risks of climate change requires a major transition in society's energy infrastructure; yet despite a growing sense of urgency, deployment of alternative emerging energy technologies has been slow and uncertain. This paper proposes a systematic, interdisciplinary framework for the integrated analysis of regulatory, legal, political, economic, and social factors that influence energy technology deployment decisions at the state level to enhance awareness of the interconnections and enable improved energy policy and planning and accelerated change in society's energy infrastructure. This framework, Socio-Political Evaluation of Energy Deployment, (SPEED), integrates analysis of laws, regulations, institutions and policy actors as well as varying regional perceptions and levels of awareness about the risks and benefits of emerging energy technologies to facilitate improved understanding of the complex interconnected components of state energy systems. While this framework has been developed with U.S. states as a model, the SPEED framework is generalizable to other countries with different sub-national structures. We present three research methods that could be applied within the SPEED framework that could be particularly helpful in understanding the integrated socio-political influences on energy technology deployment: (1) policy review and analysis, (2) media analysis, and (3) focus groups and structured interviews with key stakeholders. By integrating the fields of technology diffusion, environmental policy, comparative analysis of states, and risk perception, future empirical research conducted within this SPEED framework will improve understanding of the interconnected socio-political influences on energy technology deployment to enable energy modelers, policy-makers, energy professionals, state planners and other stakeholders to develop and implement more effective strategies to accelerate the deployment of emerging energy technologies.     

Estimating the wetland rental fee: a case study involving a Taiwan wetland

Wetlands provide many functions that are both economic and recreational and are valuable in terms of their ecological diversity, while at the same time being nonmarket value products. The purpose of this study is to estimate the optimal wetland rental through estimations of both the demand and supply functions in relation to wetland. The wetland supply function is directly estimated based on the data provided by the owners of the wetland, while the estimation of the wetland input demand function involves using the bootstrapping and contingent visitation approaches. Such estimation approaches could also be applied to other nonmarket value products that give rise to environmental externalities. The estimation of rental fee could provide a long-term leasing contract that gives the landlord with a particular rent to lease their lands to support a wetland eco-tourism park to maintain wetland for substantial management. Several environmental management policy implications are also addressed.     

Ecological footprint accounting in the life cycle assessment of products

We present and discuss ecological footprint (EF) calculations for a large number of products and services consumed in the western economy. Product-specific EFs were calculated from consistent and quality-controlled life cycle information of 2630 products and services, including energy, materials, transport, waste treatment and infrastructural processes. We formed 19 homogeneous product/process subgroups for further analysis, containing in total 1549 processes. Per group, the average contribution of two types of land occupation (direct and energy related) to the total EF was derived. It was found that the ecological footprint of the majority of products is dominated by the consumption of non-renewable energy. Notable exceptions are the EFs of biomass energy, hydro energy, paper and cardboard, and agricultural products with a relatively high contribution of direct land occupation. We also compared the ecological footprint results with the results of a commonly used life cycle impact assessment method, the Ecoindicator 99 (EI). It was found that the majority of the products have an EF/EI ratio of around 30 m²-eq. yr/ecopoint ± a factor of 5. The typical ratio reduces to 25 m² yr/ecopoints by excluding the arbitrary EF for nuclear energy demand. The relatively small variation of this ratio implies that the use of land and use of fossil fuels are important drivers of overall environmental impact. Ecological footprints may therefore serve as a screening indicator for environmental performance. However, our results also show that the usefulness of EF as a stand-alone indicator for environmental impact is limited for product life cycles with relative high mineral consumption and process-specific metal and dust emissions. For these products the EF/EI ratio can substantially deviate from the average value. Finally, we suggest that the ecological footprint product data provided in this paper can be used to improve the footprint estimates of production, import and export of products on a national scale and footprint estimates of various lifestyles.     

Green certification,heterogeneous producers,and green consumers: a welfare analysis of environmental regulations

We develop a vertical differentiation model to analyze welfare implications of environmental policies in a competitive market with production and consumption heterogeneity. Consumers with heterogeneous preferences choose between non-green and certified green products, while producers with heterogeneous production costs decide whether to engage in green production. In order for green products to be recognized by consumers, producers must join a green club. Key findings are summarized as follows. (i) The number of green producers, environmental standard, and overall welfare under the market solution are all socially sub-optimal. (ii) The introduction of a subsidy policy for greener production and standards is shown to increase social welfare, but is not Pareto optimal. (iii) A dual policy, which combines abatement subsidizes for a greener production standard and a tax charge for green certification, is shown to be the Pareto-optimal outcome.     

Integrated transitions toward sustainability: The case of water and energy policies in Israel

Transition Management literature has examined how long-term transitions could be directed toward greater sustainability. However, it has mostly taken a sectoral approach which neglects the potential relationships between environmental changes and policy dynamics in different sectors. This paper examines parallel and interrelated dynamics in the Israeli water and energy sectors by combining insights from the literature on policy dynamics, transition management, co-evolution, and policy integration. The developed approach examines how sectoral transitions may be coupled and technological regimes may co-evolve. Israel has battled water, energy and other scarcities from its formation. Consecutive dry years, the loss of stream flows, salinization of the coastal aquifer, and severe pollution are problems facing water managers, while air pollution, imported fossil fuels and carbon emissions are salient energy issues. Water and energy sectors are both in transition because earlier policies have resulted in socially-induced scarcity, degradation of environmental assets and loss of adaptive capacity to respond to future challenges. Current approaches to water and energy scarcities have evolved around technological configurations which emphasize traditional supply side solutions such as seawater desalination and additional power plants. They may be difficult to change without explicit integrative transitions management.
