As part of its work in climate change, the World Bank is engaged in developing tools to help practitioners mainstream climate risk management in development, as well as identify mitigation methodologies and options.
Climate Change Portal
The World Bank Climate Change Portal  provides quick and readily accessible global climate and climate-related data to the development community. The site is based on the Google Maps platform and allows users to access such data as outputs from climate models (GCMs), historical climate observations, natural disaster data, crop yield projections and socioeconomic data at any point on the globe. The site includes a mapping visualization tool (webGIS) that displays key climate variables, as well as linkages to World Bank databases and a spatially-referenced knowledgebase. The platform is flexible enough to include any spatial datasets, and can be tailored to specific regional or sectoral needs.
This portal also serves as a launching point for climate change adaptation tools (including the Climate Risk Screening Tool, ADAPT, as well as those developed by other institutions) and other related climate change resources, such as wikis and blogs.
Eight guidance notes , organized around a typical development project cycle, provide lessons learned, recommendations, and useful resources for integrating climate risk management and adaptation to climate change in agriculture and natural resources management projects.
Greenhouse Gas Analysis
As part of the increased emphasis the World Bank is putting on climate change issues, it has developed a variety of tools and examples to help its staff and clients more readily address the methodological, technical, and economic issues underlying the incorporation of GHG issues in project development and economic analysis.
The WBG and its Energy Sector Management Assistance Program (ESMAP) concluded there was a critical mass of operational documents and experience that would aid the design of new CFL-based residential energy efficiency programs in additional WBG member countries. Thus, ESMAP developed this “CFL Toolkit ” to compile and share important operational (design, financing and implementation) elements, documents, lessons learned, results, and other relevant data into a user-friendly format. The Toolkit does not seek to prescribe certain models or methods, but rather to share operational documents from past projects to help inform new ones. As such, the Toolkit includes key implementation/operational aspects, such as economic analysis and financial analysis (including carbon financing), elements of program design, methodologies and survey instruments for market assessment and potential, procurement guidelines, technical specifications, bidding documents, consumer surveys, awareness campaign information, environmental and safety issues related to CFLs, program evaluations, and associated Terms of Reference (TORs) for various project activities.
Renewable Energy Toolkit
The Renewable Energy ToolKit  provides a broad set of tools to assist Bank staff and country counterparts to improve the design and implementation of renewable energy (RE) projects, incorporates best practices and lessons learned from RE projects supported by the WBG and others, and is operationally oriented to address practical implementation needs at each stage in the project cycle.
The Renewable Energy ToolKit will help you to identify and design feasible renewable energy projects, determine appropriate promotional policies, identify sustainable business models, finance mechanisms and regulatory frameworks - and utilize the best available project tools, including technical standards and generic terms of reference.
Climate Change Adaptation and Mitigation in Development Programs: A Practical Guide
The purpose of this study is to draw on all available material in order to provide targeted guidance on the linkages between the design of development programs and the objectives of adapting to climate change and limiting emissions of greenhouse gases (GHGs). The report  (pdf) should be useful to practitioners in development organizations (multilateral and bilateral institutions) and countries for a better understanding of the implications of development programs and policies on climate change, as well as the implications of climate policies on budgetary and related operations.
