Open Data & Knowledge Management

Breaking barriers to data and knowledge sharing, enabling technology and knowledge transfer, and fostering collaboration to drive climate action.

The Connecting Climate Knowledge Pathway and Portfolio were borne out of our deep experience in global climate compatible development efforts, our understanding of the technical data and knowledge systems that characterise the landscape and our success in advocating, designing and implementing solutions based on the principles of Open Data.

The Pathway is designed to unleash the vast potential in efficiency gains and improved decision making possible by breaking down "knowledge silos" and barriers, and creating tools and support mechanisms to enable technology transfer between and among creators, brokers and users of knowledge.

REEEP Connecting Climate Knowledge Portfolio


Climate Tagger is a suite of tools to help knowledge-driven organizations in the climate and development arenas streamline and catalogue their data and information resources, and connect them to the wider climate knowledge community. Climate Tagger utilizes Linked Open Data and is backed by REEEP's expansive Climate Smart Thesaurus, developed by REEEP together with experts in fields ranging from climate mitigation and adaptation to economy and green growth, and even specific areas such as REDD+ (Reducing Emissions from Deforestation and Forest Degradation).


The Climate Knowledge Brokers (CKB) Group is an alliance of around 50 of the leading global, regional and national knowledge brokers specializing in climate and development information.

CKB Group brings together a diverse set of information players, from international organizations to research institutes, NGOs and networks, and covers the full breadth of climate related themes to work toward breaking down information silos and improving collaboration to advance climate compatible development. The Coordination Hub of the CKB Group was hosted by REEEP from 2014 until 2017.


The clean energy info portal is REEEP’s broadest information and data sharing tool. It targets the clean energy-interested public in emerging countries, policy makers, and project implementers. In addition to its own leading role, also shares its data sets with other information brokers, free of charge, and is a strong advocate of the Linked Open Data movement, as a neutral non-partisan source of information for all.


Climate Tagger API (formerly reegle Tagging API)

This free-of-charge service transforms floods of online data into knowledge. The Climate Tagger API (application programming interface) offers two core services to organisations that publish online resources relating to climate and clean energy:

  • Automated tagging of documents covering renewable energy, energy efficiency and climate relevant subjects
  • Suggestion of related documents from the rapidly growing content pool of items already indexed using the service

Automated tagging ensures that content is classified in a consistent way, which helps the end-user find the resources he or she is looking for.  The suggestion of related documents helps to cover more angles of a given topic and can enrich your website's offering.



REEEP publications related to data and knowledge management include:
