This report contributes to the discussion of interconnections between scarce resources by highlighting the nexus between land, water and energy (the LWE nexus). It focuses on a dynamic, integrated, and disaggregated analysis of how land, water and energy interact in the biophysical and economic systems. The report provides projections for the biophysical and economic consequences of nexus bottlenecks until 2060, highlighting that while the LWE nexus is essentially local, there can be significant large-scale repercussions in vulnerable regions, notably on forest cover and in terms of food and water security.
The analysis is based on coupling a gridded biophysical systems model with a multi-regional, multi-sectoral dynamic general equilibrium modelling assessment. Numerical insights are provided by investigating a carefully selected set of scenarios that are designed to illustrate the key bottlenecks: one scenario for each resource bottleneck, plus two scenarios that combine all bottlenecks, with and without an overlay of climate change.
This project investigates how behavioural economics can inform the design of “norm-based” environmental policies and “behaviourally robust” markets for ecosystem services. This work is part of a broader effort of a project that seeks to identify areas where behavioural economics can have the greatest impact on environmental policy design. Forthcoming: Tackling Environmental Problems with the Help of Behavioural Insights (May 2017).
This work consists of a series of spatially explicit empirical analyses of the relationships between land use patterns, socioeconomic outcomes, environmental pressures, and the use of specific policy instruments. Our latest report "Multi-objective local environmental simulator (MOLES 1.0): Model specification, algorithm design and policy applications".
This paper presents updated results for the cost of ambient air pollution in 41 countries: the 6 major emerging economies known as the BRIICS – Brazil, Russia, India, Indonesia, China and South Africa – and the 35 OECD member countries.
Watch the video - On 22 June 2017, OECD Environment Director Simon Upton presented key findings from the OECD report "Investing in Climate, Investing in Growth" during a Green Talks LIVE webinar. The report shows that integrating measures to tackle climate change into regular economic policy will have a positive impact on economic growth over the medium and long term.
Behavioural insights can help policy makers obtain a deeper understanding of the behavioural mechanisms contributing to environmental problems, and design and implement more effective policy interventions. This report reviews recent developments in the application of behavioural insights to encourage more sustainable consumption, investment and compliance decisions by individuals and firms.
Drawing on interventions initiated by ministries and agencies responsible for environment and energy, as well as cross-government behavioural insights teams, it portrays how behavioural sciences have been integrated into the policy-making process. The report covers a variety of policy areas: energy, water and food consumption, transport and car choice, waste management and resource efficiency, compliance with environmental regulation and participation in voluntary schemes. It shows what has proven to work – and what has not – in policy practice in OECD countries and beyond.
This paper describes MOLES 1.0, an integrated land-use and transport model developed with Object-Oriented Programming principles in order to combine selected characteristics from Spatial Computable General Equilibrium and microsimulation models. MOLES 1.0 models the links between urban land use, mobility patterns, urban economic activities and their environmental impacts, in particular air pollution and emissions of greenhouse gases.
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 European commission, builds on the OECD's work on quantifying the social costs of environmental externalities, particulary in recent years on the costs of air pollution.
A broader use of environmental taxation or emission trading systems would be one of the most efficient and effective ways of promoting green growth.
OECD defines EPR as an environmental policy approach in which a producer's responsibility for a product is extended to the post-consumer stage of a product's life cycle.
