A specific framework for inventorying these benefits, taking into account all the different dimensions of transboundary water management, was built and applied to the major transboundary water bodies.

New Zealanders enjoy a high environmental quality of life and access to pristine wilderness. However, New Zealand’s growth model, based largely on exploiting natural resources, is starting to show its environmental limits with increasing greenhouse gas emissions and water pollution, according to a new OECD report.

Developing countries are disproportionately affected by the rising trend of losses from climate-related extreme events. This paper uses case studies of Colombia and Senegal to examine how countries are using financial protection as part of their approaches to managing climate risks; it also identifies emerging priorities for development co-operation providers in supporting financial protection against climate risks.

This report provides an analysis of how climate change damages may affect international trade in the coming decades and how international trade can help limit the costs of climate change. It analyses the impacts of climate change on trade considering both direct effects on infrastructure and transport routes and the indirect economic impacts resulting from changes in endowments and production.

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.

This report examines the implications of regional climate governance for international trade and conversely the implications of regional trade governance for climate change action. Regional approaches to climate change governance are discussed with a specific focus on the rise of “climate clubs” and their implications for international trade.
