IEA Greenhouse Gas R&D Programme

A primary activity of IEA GHG is to undertake technical and economic evaluations of technology options for mitigating greenhouse gas emissions.


The technical and economic evaluations carried out by IEA GHG relate to all the major sectors where greenhouse gas emissions arise including the power generation, major industrial, transportation and building sectors.

The technical options considered include the assessment of individual technologies (e.g. retrofitting CO2 capture plants at existing power stations), novel power generation cycles and potential future energy system options (e.g. the hydrogen economy). In addition, IEA GHG assesses the impact that other mitigation actions can have, including those for the Non-CO2 greenhouse gases, and considers these actions in context with CO2 emission reduction actions.

Technical evaluations

IEA GHG evaluates the technologies using a transparent and consistent methodology that allows direct comparison of the technology options and other actions. In this way, IEA GHG provides objective information to its members. Such information can then be used within the policy-making, industrial, scientific and academic communities. Through its research activities IEA GHG aims to identify key gaps in knowledge and promote activities to fill these gaps. Such activities can be undertaken by IEA GHG or by its members.

The technical evaluations completed by IEA GHG are provided as detailed technical reports to members. These reports aim to increase knowledge about the role of mitigation policies.

Obtaining a report

The Technical Reports are available to individuals and organisations in all member countries & to all sponsor organisations;upon publication. These become freely available to those from non-member countries after a six month period and will be added to the list below. If you are from a member country or sponsor and would like a recently published report please contact This email address is being protected from spambots.

In addition, IEAGHG publishes the results of its work at various conferences around the world and in technical journals. By doing this IEA GHG aims to publicise summaries of its research activities to a broader audience including non-members.
