Green economy

The Green Economy is an alternative vision for growth and development; one that can generate economic development and improvements in people’s lives in ways consistent with advancing also environmental and social well-being. One significant component of a green economy strategy is to promote the development and adoption of sustainable technologies. The overall objective of this article is to discuss a number of challenges encountered when pursuing sustainable technological change, and that need to be properly understood by policy makers and professionals at different levels in society. We also identify some avenues for future research. The discussions center on five challenges: (a) dealing with diffuse – and ever more global – environmental risks; (b) achieving radical and not just incremental sustainable technological change; (c) green capitalism and the uncertain business-as-usual scenario; (d) the role of the state and designing appropriate policy mixes; and (e) dealing with distributional concerns and impacts. The article argues that sustainable technological change will require a re-assessment of the roles of the private industry and the state, respectively, and that future research should increasingly address the challenges of identifying and implementing novel policy instrument combinations in various institutional contexts.

The green economy transition and sustainable technological change

Over the last decade, a frequent claim has been that the traditional economic models need to be reformed in order to address climate change, biodiversity losses, water scarcity, etc., while at the same time addressing key social and economic challenges. The global financial crisis in 2008–2009 spurred this debate [4], and these concerns have been translated into the vision of a ‘green economy’ (e.g., [31, 33, 48, 54, 55]). Furthermore, in 2015, countries world-wide adopted the so-called 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals. These goals recognize that ending world poverty must go hand-in-hand with strategies that build economic growth but also address a range of various social needs including education, health, social protection, and job creation, while at the same time tackling environmental pollution and climate change. The sustainable development goals thus also establish a real link between the ecological system and the economic system. They also reinforce the need for a transition to a green economy, i.e., a fundamental transformation towards more sustainable modes of production and consumption.

In this article, we focus on a particularly important component of such a transition, namely the development of sustainable technological change, i.e., production and consumption patterns implying profoundly less negative impacts on the natural environment, including the global climate. Specifically, the article addresses a number of key challenges in supporting – and overcoming barriers to – sustainable technological change. These challenges are presented with the ambition to communicate important lessons from academic research to policy makers and professionals as well as the general public.

Addressing climate and environmental challenges, clearly requires natural scientific knowledge as well as engineering expertise concerning the various technical solutions that can be adopted to mitigate the negative impacts (e.g., carbon-free energy technologies). However, pursuing sustainable technological change is also a societal, organizational, political, and economic endeavor that involves several non-technical challenges. For instance, the so-called transitions literature recognizes that many sectors, such as energy generation, water supply etc., can be conceptualized as socio-technical systems and/or innovation systems [24, 40]. These systems consist of networks of actors (individuals, private firms, research institutes, government authorities, etc.), the knowledge that these actors possess as well as the relevant institutions (legal rules, codes of conduct, etc.). In other words, the development of, for instance, new carbon-free technologies may often require the establishment of new value chains hosting actors that have not necessarily interacted in the past; this necessitates a relatively long process that can alter society in several ways, e.g., through legal amendments, changed consumer behavior, distributional effects, infrastructure development and novel business models.

In other words, beyond technological progress, economic and societal adjustment is necessary to achieve sustainable technological change. In fact, history is full of examples that illustrate the need to address the organizational and institutional challenges associated with technological change and innovation. In hindsight, the societal impacts of electricity in terms of productivity gains were tremendous during the twentieth century. Still, while electrical energy was discovered in the late 1870s, in the year 1900, less than 5% of mechanical power in American factories was supplied by electric motors and it took yet another 20 years before their productivity soared [14]. An important reason for the slow diffusion of electric power was that in order to take full advantage of the new technology, existing factories had to change the entire systems of operation, i.e., the production process, the architecture, the logistics as well as the ways in which workers were recruited, trained and paid.Footnote1 A similar story emerges when considering the impact of computers on total productivity during the second half of the twentieth century. For long, many companies invested in computers for little or no reward. Also in this case, however, the new technology required systemic changes in order for companies to be able to take advantage of the computer. This meant, for instance, decentralizing, outsourcing, and streamlining supply chains as well as offering more choices to consumers [9].

This key argument that the adoption of new technology has to be accompanied by systemic changes, applies both to the company as well as the societal level. Any novel solutions being developed must take into account the complexity of the interdependencies between different types of actors with various backgrounds, overall market dynamics, as well as the need for knowledge development and institutional reforms. In fact, the need for systemic changes may be particularly relevant in the case of green technologies, such as zero-carbon processes in the energy-intensive industries (see further below).

Against this background, the issue of how to promote sustainable technological change has received increasing attention in the policy arena and in academic research. The main objective of this article is therefore to discuss some of the most significant societal challenges in pursuing such change, and outline key insights for policy makers as well as important avenues for future research. In doing this, we draw on several strands of the academic literature. The article centers on the following five overall challenges:

The first two challenges address the various types of structural tasks that are required to pursue sustainable technological change, and the barriers that have to be overcome when pursuing these tasks. The remaining points concern the role and the responsibility of different key actors in the transition process, not least private firms and government authorities. Each of these five challenges in turn involves more specific challenges, and these are identified and elaborated under each heading. We also provide hints about how to address and manage these challenges, but specific solutions will likely differ depending on the national or regional contexts. The paper concludes by briefly outlining some key avenues for future research, and with an emphasis on research that can assist a green socio-technical transition.Footnote2

Dealing with diffuse – and ever more global – environmental risks

With the advent of modern environmental policy in the 1960s, stringent regulations were imposed on emissions into air and water. However, the focus was more or less exclusively on stationary pollution sources (i.e., industrial plants), which were relatively easy to monitor and regulate, e.g., through plant-specific emission standards. In addition, during this early era there was a strong emphasis on local environmental impacts, e.g., emissions into nearby river basins causing negative effects on other industries and/or on households in the same community.

Over the years, though, the environmental challenges have increasingly been about targeting various types of diffuse emissions. These stem from scattered sources such as road transport, shipping, aviation, and agriculture. Pollution from diffuse sources takes place over large areas and individually they may not be of concern, but in combination with other diffuse sources they can cause serious overall impacts. The growing importance of global environmental challenges such as climate change in combination with globalization and more international trade in consumer products, adds to this challenge. Managing these issues often requires international negotiations and burden-sharing, which in itself have proved difficult [12]. The difficulties in reaching a stringent-enough global climate agreement illustrate this difficulty.

Diffuse emissions are typically difficult to monitor and therefore also to regulate. For instance, environmental authorities may wish to penalize improper disposal of a waste product since this would help reduce various chemical risks, but such behavior is typically clandestine and difficult to detect. Plastic waste is an apt example; it stems from millions of consumer products, is carried around the world by the currents and winds, and builds up microplastics, particularly in the sea. Many dangerous substances, including chemicals such as solvents and phthalates, are embedded in consumer products, out of which many are imported. Monitoring the potential spread of these substances to humans and the natural environment remains difficult as well. Technological innovation that permits better tracing and tracking of materials should therefore be a priority (see also [21]).

In order to address these diffuse environmental impacts, society has to find alternative – yet more indirect – ways of monitoring and regulating them. This could translate into attempts to close material cycles and promote a circular economy, i.e., an economy in which the value of products, materials and resources are maintained as long as possible [19]. In practice, this implies an increased focus on reduction, recycling and re-use of virgin materials [30], material and energy efficiency, as well as sharing of resources (often with the help of various digital platforms such as Uber and Airbnb). In other words, rather than regulating emissions as close to damage done as possible, the authorities may instead support specific activities (e.g., material recycling) and/or technologies (e.g., low-carbon production processes) that can be assumed to correlate with reduced environmental load.

Addressing diffuse emissions in such indirect ways, though, is not straightforward. In several countries, national waste management strategies adhere to the so-called waste hierarchy (see also the EU Waste Framework Directive). This sets priorities for which types of action should be taken, and postulates that waste prevention should be given the highest priority followed by re-use of waste, material recycling, recovery of waste and landfill (in that order). Even though research has shown that this hierarchy is a reasonable rule of thumb from an environmental point of view [42], it is only a rule of thumb! Deviations from the hierarchy can be motivated in several cases and must therefore be considered (e.g., [58]).Footnote3

One important way of encouraging recycling and reuse of products is to support product designs that factor in the reparability and reusability of products. Improved recyclability can also benefit from a modular product structure (e.g., [20]). However, this also comes with challenges. Often companies manufacture products in such ways that increase the costs of recycling for downstream processors, but for institutional reasons, there may be no means by which the waste recovery facility can provide the manufacturer with any incentives to change the product design [11, 46]. One example is the use of multi-layer plastics for food packaging, which could often be incompatible with mechanical recycling.

While the promotion of material and energy efficiency measures also can be used to address the problem of diffuse environmental impacts, it may be a mixed blessing. Such measures imply that the economy can produce the same amount of goods and services but with less material and energy inputs, but they also lead to a so-called rebound effect [27]. Along with productivity improvements, resources are freed and can be used to increase the production and consumption of other goods. In other words, the efficiency gains may at least partially be cancelled out by increased consumption elsewhere in the economy. For instance, if consumers choose to buy fuel-efficient cars, they are able to travel more or spend the money saved by lower fuel use on other products, which in turn will exploit resources and lead to emissions.

Finally, an increased focus on circular economy solutions will imply that the different sectors of the economy need to become more interdependent. This interdependency is indeed what makes the sought-after efficiency gains possible in the first place. This in turn requires new forms of collaborative models among companies, including novel business models. In some cases, though, this may be difficult to achieve. One example is the use of excess heat from various process industries; it can be employed for supplying energy to residential heating or greenhouses. Such bilateral energy cooperation is already quite common (e.g., in Sweden), but pushing this even further may be hard and/or too costly. Investments in such cooperation are relation-specific [60], i.e., their returns will depend on the continuation of the relationships. The involved companies may be too heterogeneous in terms of goals, business practices, planning horizons etc., therefore making long-term commitment difficult. Moreover, the excess heat is in an economic sense a byproduct, implying that its supply will be constrained by the production of the main product. Of course, this is valid for many other types of waste products as well, e.g., manure digested to generate biogas, secondary aluminum from scrapped cars.

In brief, the growing importance of addressing diffuse emissions into the natural environment implies that environmental protection has to build on indirect pollution abatement strategies. Pursuing each of these strategies (e.g., promoting recycling and material efficiency), though, imply challenges; they may face important barriers (e.g., for product design, and byproduct use) and could have negative side-effects (e.g., rebound effects). Moreover, a focus on recycling and resource efficiency must not distract from the need to improve the tracing and tracking of hazardous substances and materials as well as provide stronger incentives for product design. Both technological and organizational innovations are needed.
