Energy policies include provisions for feed-in-tariffs, but these are largely deemed to be too low to attract private investment. A lack of institutional capacity and human resources in key policy and decision making units related to environment acts as a barrier to mainstreaming of environmental targets across sector policies and plans, especially energy. Indirect fossil fuel subsidies support and incentivise state-owned enterprises in the energy sector which are investing in fossil fuels, and capped fuel prices mean that renewable energy and energy efficiency investments are not always viable. According to OECD DAC statistics, in 2014, just over USD 1.5 billion in development finance flows supported climate change projects in Viet Nam, with around half (47%) focusing on climate change mitigation, a third supporting climate change adaptation (34%) and the rest supporting both mitigation and adaptation.
