Beyond the adoption of the umbrella agreements, collaboration on energy matters was further reinforced by the "Memorandum of Understanding on Cooperation in the Field of Energy between the EU and Ukraine" (MoU) signed on 1 December 2005 in the context of the implementation of the EU-Ukraine Action Plan. The MoU sets out how the two sides plan to organise their work to advance convergence in the seven areas highlighted in the Action Plan.

The MoU establishes a joint strategy towards the progressive integration of the Ukrainian energy market with that of the EU and consists of road maps covering five specific areas:

Nuclear safety;
Integration of the electricity and gas markets;
Enhancing the security of energy supplies and the transit of hydrocarbons;
Improving the effectiveness, safety and environmental standards of the coal sector; and
Increasing cooperation in energy efficiency and the promotion of RES.

For each of these five areas, joint expert groups have been established and considerable work is being undertaken in all thematic areas.
