Redefining innovation — eco-innovation research and the contribution from ecological economics

While innovation processes toward sustainable development (eco-innovations) have received increasing attention during the past years, theoretical and methodological approaches to analyze these processes are poorly developed. Against this background, the term eco-innovation is introduced in this paper addressing explicitly three kinds of changes towards sustainable development: technological, social and institutional innovation. Secondly, the potential contribution of neoclassical and (co-)evolutionary approaches from environmental and innovation economics to eco-innovation research is discussed. Three peculiarities of eco-innovation are identified: the double externality problem, the regulatory push:pull effect and the increasing importance of social and institutional innovation. While the first two are widely ignored in innovation economics, the third is at the least not elaborated appropriately. The consideration of these peculiarities may help to overcome market failure by establishing a specific eco-innovation policy and to avoid a ‘technology bias’ through a broader understanding of innovation. Finally, perspectives for a specific contribution of ecological economics to eco-innovation research are drawn. It is argued that methodological pluralism as established in ecological economics would be very beneficial for eco-innovation research. A theoretical framework integrating elements from both neoclassical and evolutionary approaches should be pursued in order to consider the complexity of factors influencing innovation decisions as well as the specific role of regulatory instruments. And the experience gathered in ecological economics integrating ecological, social and economic aspects of sustainable development is highly useful for opening up innovation research to social and institutional changes.

Determinants of eco-innovations by type of environmental impact — The role of regulatory push/pull, technology push and market pull

Empirical analyses of the determinants of environmental innovations were rarely able to distinguish between different areas of environmental impacts. The paper tries to close this gap by employing a new and unique dataset based on the German Community Innovation Survey conducted in 2009. The main purpose of the paper is to test whether different types of eco-innovations (according to their environmental impacts) are driven by different factors. Besides a complex set of different supply, firm specific and demand factors, the literature on the determinants of environmental innovations accentuates the important role of regulation, cost savings and customer benefits. We find that current and expected government regulation is particularly important for pushing firms to reduce air (e.g. CO2, SO2 or NOx) as well as water or noise emissions, avoid hazardous substances and increase recyclability of products. Cost savings are an important motivation for reducing energy and material use, pointing to the role of energy and raw materials prices as well as taxation as drivers for eco-innovation. Customer requirements are another important source for eco-innovations, particularly with regard to products with improved environmental performance and process innovations that increase material efficiency, reduce energy consumption and waste and the use of dangerous substances. Firms confirm a high importance of expected future regulations for all environmental product innovations.

Steps towards indicators of sustainable development: Linking economic and ecological concepts

Abstract Conceptions of defining and measuring sustainable development can broadly be placed in two categories: weak and strong sustainability. The concept of weak sustainability is based on neo-classical economic theory and assumes that manufactured and natural capital are close substitutes. This means that costs of environmental deterioration (e.g., forest damage) can be compensated by benefits from manufactured capital (e.g., income). Thus, environmental damages are valued in monetary units. The concept of strong sustainability denies the degree of substitution that weak sustainability assumes, at least for some critical elements of natural capital. This paper pledges for strong sustainability indicators, especially for critical loads and critical levels. Since the costs and benefits of avoiding critical impacts have to be taken into account, a combination of strong and weak sustainability indicators—means a linkage of ecological (physical) and economic (monetary) approaches—should be suggested.

Determinants of environmental product and process innovation

While integrated product policy (IPP) receives increasing attention, it is still not well understood which factors and policy instruments influence the environmental performance of products. Thus this paper investigates the determinants of innovative behaviour in companies with regard to various areas of end-of-pipe and integrated environmental protection, including integrated product innovation. It pays particular attention to the influence of environmental policy instruments on product and process innovation. Its approach could be placed somewhere between environmental and industrial economics: in contrast to the up to now dominant approach of environmental economics, it integrates discoveries from the field of innovation research. The paper takes its data from the Mannheim Innovation Panel (1996), complemented by a subsequent telephone survey of environmental innovators. In a multivariate analysis, significant influence from strategic market goals on environment-related product innovation becomes evident. This differs from environment-related process innovation, which is mainly determined by regulation. With respect to individual environmental policy instruments, a significant influence of so-called ‘soft’ regulation (e.g. labels, eco-audits) on product-integrated environmental innovation can be discerned.

The effect of environmental and social performance on the stock performance of european corporations

This paper examines the effect of sustainability performance of European corporations on their stock performance, measured as the average monthly stock return from 1996 to 2001. The econometric analysis is based on common empirical asset pricing models, particularly on the multifactor model according to Fama and French (1993, Journal of Financial Economics, 33:3–56). The consideration of sustainability performance is two-fold: The average sustainability performance of the industry in which a corporation operates and the relative sustainability performance of a corporation within a given industry. The main result is that the average environmental performance of the industry has a significantly positive influence on the stock performance. In contrast, the average social performance of the industry has a significantly negative influence. The variables of the relative environmental or social performance of a corporation within a given industry have no significant effect on the stock performance. As a by-product, the econometric analysis implies that some results of Fama and French (1993, 1996, The Journal of Finance, LI (1):55–84) regarding the risk factors of the multifactor model need not hold true for different observation periods, for different stock markets, and for the use of single stocks (instead of portfolios).

The impact of regulation-driven environmental innovation on innovation success and firm performance

The impact of environmental innovations on firm performance is ambiguous. On the one hand, regulatory-driven environmental innovation may impose additional costs to firms and lower their profits. On the other hand, eco-innovators could profit from lower uncertainty in innovation due to regulatory standards and demand-generating effects of regulation. In this paper we analyse (a) whether regulation-driven environmental innovation generate similar innovation success compared to other types of product and process innovation, and (b) whether regulation-driven environmental innovation increase or decrease firm success (as measured by return on sales). Using firm data from the German innovation survey, we find that both product and process innovations driven by environmental regulation generate similar success in terms of sales with new products and cost savings as other innovations do. However, we find different effects when looking on the field of environmental regulation that triggered innovations. Regulations in favour of sustainable mobility contribute to higher sales with market novelties while regulations in the field of water management lower this type of innovation success. With regard to a firm’s price-cost margin, new processes implemented in order to comply with environmental regulation requirements lower profitability, indicating higher costs for this type of innovation which cannot be passed on prices. Higher profit margins can be observed for firms with innovations triggered by regulations on recycling and waste management as well as on resource efficiency.

Increasing Energy and Resource Efficiency Through Innovation - An Explorative Analysis Using Innovation Survey Data

Energy and resource efficiency innovations (EREIs) are often seen as win-win opportunities for both the economic and the environmental performance of firms. It is thus worth asking how the innovation activities and performance of firms with regard to energy and resource efficiency look like: Do EREI firms follow distinct innovation strategies? Do EREIs spur or limit innovation success? And what are the particular features of EREI firms compared to conventional innovators? Using German innovation data, we find that EREIs are determined by a larger set of technology-push and market-pull factors. On the supply side, R&D budgets, research infrastructure and networking with other firms are important factors of influence, while on the demand side increased productivity and cost reductions are decisive, as well as improved product quality. On the other hand, EREIs are complex activities which also need regulatory incentives. Although EREIs are not more successful compared to conventional innovations, they contribute substantially to the economic success of firms.

The employment impact of cleaner production on the firm level: empirical evidence from a survey in five European countries

This paper analyses the determinants of employment reactions of firms when environmental innovations have been carried out. It differentiates hereby between employment increases and decreases. The data stem from a telephone survey covering more than 1500 firms in five European countries that have introduced environmental innovations recently. Environmentally beneficial product and service innovations create jobs in contrast to process innovations. Employment changes occur in the wake of major innovations only and especially in small firms and firms with positive sales expectations. While innovations purely motivated by environmental goals tend not to have employment effects, cost reductions envisaged by environmental innovations reduce employment. We detect skill biased technological change of environmental innovations. Environmental innovations have a small but positive effect on employment on the firm level. Thus, environmental support programmes do not counteract labour market policy. A further shift from end-of-pipe technologies to cleaner production, especially towards product and service innovations, would be beneficial for the environment and creates jobs.

Environmental Innovation and Employment Dynamics in Different Technology Fields - An Analysis Based on the German Community Innovation Survey 2009

The employment effects of environmental technologies are in the focus of politicians but there are only few studies analyzing these effects for different environmental innovation fields. We use the 2009 wave of the German part of the Community Innovation Panel (CIS) allowing for such an analysis at the firm level. The main focus of the paper lies on the analysis of the adaptation behavior of firms with respect to the relationship of employment and (environmental) innovation. We use an endogenous switching regression approach to take the simultaneous character of innovation activities and employment demand into consideration. Our econometric analysis shows that innovative firms in general are characterized by a significantly more dynamic employment development. Especially the realization of environmental process innovations leads to a higher employment within the firm. The theoretical background of this finding is that process innovation induced cost savings improve the competitiveness of firms. This has a positive effect on demand and thus also increases employment. A more detailed analysis by different environmental innovation fields shows that material and energy savings are positively correlated to employment because they especially help to increase the profitability and competitiveness of the firm. On the other side, air and water process innovations that are still dominated by end-of-pipe technologies have a negative impact on the employment development.

Lead Markets of Environmental Innovations: A Framework for Innovation and Environmental Economics

Environmental regulations often want to stimulate the generation and adoption of ecoefficient innovations. An important argument in the public debate is also the creation of new markets for environmentally benign products, processes and services that other countries adopt and therefore generate export opportunities for the pioneering country. The research so far concentrated on the question on how national environmental regulation can induce innovations. The question addressed in this paper is whether environmental regulations can create lead markets, enabling local firms to export innovations that are induced by local market conditions and national regulations. We identify relevant factors for lead markets of environmental innovations. So far, the lead market concept in innovation economics has only been applied to innovations in general. We extend the lead market model to environmentally friendly innovations, considering their peculiarities, in particular the public good character of environmental benefits and the role of regulations. The approach is applied to two case studies: fuel-efficient passenger cars and wind energy. In both cases, one country adopted the innovation first. Later, other countries followed the same innovation design favoured by the lead market. The lead market became a large exporter in the wind generation and car industry respectively. We discuss the regulations employed and the reasons for the international success of the innovations induced by them. We find that strict regulation has created lead markets when it was supported by a global demand or regulatory trend.
