However, the Indonesian Government still has difficulty in adjusting Indonesia's energy needs for national development with efforts to mitigate climate change in the energy sector. This has caused a lack of efforts by the Government to mitigate climate change in the energy sector.

There has been no review of these mitigation efforts causing Indonesia's commitment in the Paris Agreement 2015 to have no implications for mitigation efforts through the National House Gas Action Plan.Keyword : Paris Agreement 2015-Climate Change Mitigation-Indonesia Energy Sector Policy]]>
