Les changements dans la structure du commerce mondial augmenteront les distances de transport de 12 %. La route du Pacifique Nord remplacera la route de l’Atlantique Nord en tant que principale route commerciale.
Micro-organisms play a fundamental role in the environment. Yet their role is the result of complex biogeochemical processes by consortia of micro-organisms and the function of individual species is not clear in many cases.
This publication provides an overview of the current situation and relevant developments in environmental microbiology, as well as its potential application, which covers: use of micro-organisms for agriculture, production purposes, bioremediation, and cleaning purpose; environmental applications of microbial symbionts of insects; and environmental risk/safety assessment of the deliberate release of engineered micro-organisms.

Ecosystem accounting is a relatively new and emerging field dealing with integrating complex biophysical data, tracking changes in ecosystems and linking those changes to economic and other human activity. Considering the increasing demand for statistics on ecosystems within analytical and policy frameworks on environmental sustainability, human well-being and economic growth and development, there has been an increasing urgency to advance this emerging field of statistics.
Although considerable experience exists in related areas of statistics such as land cover and land use statistics, the integration of these and other information into an ecosystem accounting framework is new. Also, there is considerable existing expertise in the ecosystem sciences and economics fields that is relevant, and again it is the focussing of these different areas of expertise on the proposed ecosystem accounting approach that is new.
SEEA-Experimental Ecosystem Accounting provides a synthesis of the current knowledge in this area and provides a starting point for the development of ecosystem accounting at national and sub-national levels. It represents an important step forward on ecosystem accounting, providing a common set of terms, concepts, accounting principles and classifications; an integrated accounting structure of ecosystem services and ecosystem condition in both physical and monetary terms; and the recognition of spatial areas as forming the basic focus for measurement.

This brochure provides an overview of the OECD work on economy-environment modelling.
In today’s hard times, policy-makers can find it difficult to sell their environmental policies. To many, these policies represent a burden on the economy.
Personal behaviour and choices in daily life, from what we eat to how we get to work or heat our homes, have a significant – and growing – effect on the environment. But why are some households greener than others? And what factors motivate green household choices? Answering these questions is vital for helping governments design and target policies that promote "greener" behaviour.
This report focuses on personal transport choices. It presents the results of follow-up analysis of the 2011 OECD Survey on Environmental Policy and Individual Behaviour Change (EPIC) survey where econometric techniques are applied.
Cette étude analyse quelques-uns des problèmes clés auxquels les pays de l’OCDE et leurs partenaires pourraient être confrontés dans les 50 prochaines années si les grandes tendances mondiales se confirment en matière de croissance, d’échanges, d’inégalités et de pressions environnementales.
This report focuses on households’ behaviour in relation to water use. It presents the results of follow-up analysis of the 2011 OECD Survey on Environmental Policy and Individual Behaviour Change (EPIC) where econometric techniques are applied. The analysis shows that households whose bill depends on actual water use are unambiguously more likely to exhibit pro-environmental behaviours in terms of water use.
