    Analyse coûts-avantages et environnement - Avancées théoriques et utilisation par les pouvoirs publics

    La présente publication examine les avancées récentes de l’analyse coûts-avantages (ACA) environnementale. Celle-ci correspond à l’application de l’ACA aux projets ou aux politiques qui visent explicitement à améliorer la qualité de l’environnement ou qui ont, d’une manière ou d’une autre, un effet indirect sur les milieux naturels. Cette publication s’appuie sur l’ouvrage précédent de l’OCDE rédigé par David Pearce et al. (2006), qui partait du constat que la conjonction d’un certain nombre d’avancées de l’ACA modifiait la manière dont bien des économistes recommanderaient de mettre en œuvre cet instrument, surtout dans le contexte de projets ou de politiques ayant des impacts environnementaux considérables.
    Cette publication n’a pas seulement pour principal objectif d’évaluer les progrès accomplis : elle cherche également à déterminer en quoi certaines évolutions illustrent des questions thématiques centrales ayant des conséquences pour l’application concrète de l’ACA environnementale dans le cadre de l’élaboration des politiques et de l’évaluation des projets d’investissement.
    Le thème sans doute le plus important a trait à la contribution de l’économie du climat face au défi que constitue l’évaluation des mesures publiques visant à atténuer le changement climatique (ou à s’y adapter). Les travaux dans ce domaine ont accru l’intérêt porté au mode d’évaluation des coûts et des avantages à très long terme et ils ont notamment montré à quel point les procédures classiques de détermination du taux d’actualisation social deviennent problématiques dans un contexte intergénérationnel et quelles pourraient être les nouvelles approches requises. La contribution de l’économie du climat a également suscité une réflexion plus poussée sur l’incertitude dans le cadre de l’ACA, en particulier en présence d’effets incertains qui peuvent avoir des impacts (négatifs) de grande ampleur.

    Assessing the economic valuation of the benefits of regulating chemicals - Environment Working Paper

    This paper reviews and compares five case studies on quantification and economic valuation of benefits in cost-benefit analyses (CBAs) of regulating phthalates, mercury, PFOA (perfluoro-octanic acid) and its salts, NMP (1 methyl-2-pyrroloidine) and formaldehyde. The case studies had all been carried out as part of the SACAME project, and the purpose of the present paper is to draw out cross-cutting findings from these studies.

    The costs and benefits of regulating chemicals

    The SACAME project supports the socio-economic analysis of chemicals by allowing a better quantification and monetisation of health- and environmental impacts. This research, funded by the EC, builds on the OECD work on quantifying the social costs of environmental externalities, particulary in recent years on the costs of air pollution. Four new reports now available.

    Insights blog: Steering urban sprawl

    Cities with highest average population densities in the world are facing the challenge of urban sprawl. Finding sustainable solutions to reduce sprawl demands rethinking urban space and weighing the private benefits of low density living–my house and garden–against social, environmental and infrastructure costs.

    Rethinking Urban Sprawl - Moving Towards Sustainable Cities

    This report provides a new perspective to the nature of urban sprawl and its causes and environmental, social and economic consequences. This perspective, which is based on the multi-dimensionality of urban sprawl, sets the foundations for the construction of new indicators to measure the various facets of urban sprawl. The report uses new datasets to compute these indicators for more than 1100 urban areas in 29 OECD countries over the period 1990-2014. It then relies on cross-city, country-level and cross-country analyses of these indicators to provide insights into the current situation and evolution of urban sprawl in OECD cities. In addition, the report offers a critical assessment of the causes and consequences of urban sprawl and discusses policy options to steer urban development to more environmentally sustainable forms.

    Economic valuation in 1-Methyl-2-pyrrolidone (NMP) regulation - Environment Working Paper

    This paper gives an overview of economic assessments of the benefits of the control of 1-Methyl-2-pyrrolidone, an organic solvent, used in a number of sectors. Health risks associated with the manufacture of NMP include the risk of stillbirth and developmental retardation to pregnant workers, as well as a variety of chronic and acute effects, including respiratory effects.
