The provision of water supply and sanitation services is particularly vulnerable to projected changes in climate conditions (temperature and precipitation among others), in the frequency and intensity of extreme weather events, as well as and in the projected rise in sea-level and the intensification of storm surges. The process of climate proofing investment projects aims both at assessing the climate risk to a project's future costs and benefits, and undertaking a technical and economic analysis of options to alleviate or mitigate those risks. Accounting for climate change at the outset of the project cycle implies that decisions about project design, and the adoption and timing of climate-proofing measures be informed with the possible impacts of climate change in the initial phases of the project cycle so that decisions of an irreversible nature will be avoided. This publication presents a step-by-step methodological approach to assist project teams in managing climate change risk in the context of water supply and sanitation investment projects.

Climate change represents an increasing threat to the continued development of the people, preservation of ecosystems, and economic growth of Asia and the Pacific. Mainstreaming climate risk management in all aspects of development is thus key to an effective transition to climate-resilient development pathways. ADB's climate risk management framework aims to reduce risks resulting from climate change to investment projects in Asia and the Pacific. A key step in this framework is the technical and economic valuation of climate-proofing measures. This report describes the conduct of the cost-benefit analysis of climate proofing investment projects. An important message is that the presence of uncertainty about climate change does not invalidate the conduct of the economic analysis of investment projects, nor does it require a new type of economic analysis. However, the presence of uncertainty does require a different type of decision-making process in which technical and economic expertise combine to present decision makers with the best possible information on the economic efficiency of alternative designs of investment projects.

This publication provides a step-by-step methodological approach to help project teams assess and incorporate climate change adaptation measures into energy investment projects. While the focus of the guidelines is at the project level, an improved understanding of climate change impacts should also be used to incorporate climate change considerations into energy planning and policy at the country level.

This publication aims to present a step-by-step methodological approach to assist project teams to incorporate climate change adaptation measures into transport sector investment projects. While the focus of the publication is on the project level, an improved understanding of climate change impacts should also be used in the design of infrastructure planning and development policies and strategies to ensure appropriate resource allocation. Though the transport sector includes roads, waterways, rails, and airborne transport, this publication focuses solely on road infrastructure.

The Climate Change Operational Framework 2017-2030 is intended to provide broad direction and guidance for enhancing resilience and strengthening climate actions in the operations and business processes of the Asian Development Bank (ADB). It positions ADB to facilitate, collaboratively and proactively, a regional shift toward a low greenhouse gas emissions and climate-resilient development path. The operational framework provides guidance across all ADB sector and thematic groups to support climate adaptation and mitigation actions, operationalizing ADB's commitment to provide at least $6 billion per year in climate change financing from its own resources by 2020. It outlines actions and the institutional measures to be implemented to enable ADB to meet the climate needs of its developing members.

This publication aims to present a step-by-step methodological approach to assist project teams assess and incorporate climate change adaptation measures into investment projects in agriculture, rural development, and food security. While the focus of the publication is at the project level, an improved understanding of climate change impacts should also be used to incorporate climate change considerations into agriculture planning and policy at the country level. Though rural development projects include irrigation, rural infrastructure, agriculture production, and natural resource management, this report focuses mainly on irrigation infrastructure projects and agriculture production projects.

The Asia and Pacific region is vulnerable to extreme temperatures, flooding by heavy rainfall, sea level rise, coastal erosion, and damage by tropical cyclones. This technical note provides information that supports climate risk assessment experts undertaking early stages of project development in the region. The information is grouped into four major categories: inventories of national emissions, climate risks, vulnerability, and impacts; historic weather, climate, and environmental change; regional climate change projections; and climate change impacts and adaptation. The note also identifies opportunities for capacity development in key skills such as geospatial analysis, data testing and post-processing, regional climate downscaling, and impact assessment.
