Öz Meeting targets aimed at tackling the climate change challenge requires moving towards an energysaving and low-carbon development. These targets can only be met with major reductions in carbon emissions from the low carbon technologies. The low carbon technology gap between developed countries and developing countries leads to technology transfer and transaction needs.
