Climate change is an imminent global threat endangering human security through worsening natural disasters. If we continue. If our current economic and social life style is continued in an unsustainable manner, greenhouse gas emissions (GHGs) is projected to soar highly and that the 21st century will encounter serious challenges. In this regard, Bangkok Metropolitan Administration (BMA) needs to accelerate actions to respond to climate change according to the Bangkok Master Plan on Climate Change 2013 – 2023 so that to drive and conduct the measures on GHG mitigation and adaptation to accomplish in alignment with the vision and target through domestic and oversea cooperation.

      According to the Master Plan, the implementation consists of 5 key sectors with focusing on both 1) environmentally sustainable transport, 2) energy efficiency and alternative energy, 3) efficient solid waste management and wastewater treatment, 4) green urban planning sector, and 5) adaptation planning. In order to develop a comprehensive and action-oriented approach, it contains a package of Business as Usual (BAU) setting, target setting for GHG mitigation, and actual mitigation and adaptation measures. For conducting measures under the Master Plan in response to GHG reduction and adaptation to climate change, it is considered and selected according to priority, urgency, feasibility, and integration into the duty of BMA. In addition, Monitoring & Evaluation (M&E) as well as the Measurement, Reporting, and Verification (MRV) mechanisms were developed to ensure the successful implementation of the Master Plan.

      As for the estimate of GHG emission quantity, GHGs emissions in Bangkok will increase significantly if the current socio-economic conditions are maintained per BAU assumptions. It is expected that future met GHGs emission in Bangkok could grow from 43.87 million tons CO2 equivalent by the year 2013, to as high as 53.74 Mt-CO2 equivalent by the year 2020. However, this Master Plan, if implement properly, would yield total net GHG emissions in the year 2020 of 46.44 Mt-CO2 equivalent, approximately 13.57%. According to the quantitative assessment of the Comprehensive Review, it revealed that the amount of GHG emissions of 42.75 Mt-CO2e in 2016, compared to the 2016 BAU. The level of emissions has drawn a steady pathway so far towards the achievement of the goal.
