The escalating concerns over climate change have propelled industries worldwide to seek innovative strategies for mitigating greenhouse gas emissions. Within the energy sector, Carbon Capture and Storage (CCS) technology emerges as a promising solution to curtail emissions and foster sustainable development aims for the net zero approach. This research delves into the role of government support in expediting CCS adoption for the maximum potential of 9.79 MtCO₂ storage from six major refinery plants. The refineries mentioned above are anticipated to necessitate an initial capital investment of approximately 18,307 million THB. This research focuses on potential business model proposals appropriate for a country’s context, specifically, applying CCS technology to the Thai oil refining sector. To achieve the realization of CCS within the context of this study, a combination of three essential measures will be required: tax incentives, carbon credits, and grants. This process will commence with the implementation of tax incentives, followed by an increase in the carbon price within the country. Finally, the establishment of a dedicated fund, funded through deductions from oil excise tax revenue, will play a pivotal role in facilitating the necessary financial support for the emergence of CCS.

The tourism sector is a vital contributor to Thailand’s economy but also a significant source of greenhouse gas (GHG) emissions. This study aims to align Thailand’s Sustainable Tourism Goals (STGs), established in late 2023, with the nation’s GHG reduction targets. Adapted from the United Nations Sustainable Development Goals (SDGs), the STGs encompass 17 dimensions and 86 indicators but currently lack explicit quantitative targets. This research identifies key measurable criteria in energy (STGs 7, 11, 13), waste management (STG 12), and water management (STG 6), focusing on data from large hotels to assess their GHG emissions and reduction potential. The findings indicate that implementing STG measures could reduce emissions by 527,291 tCO₂eq, equivalent to 4.80% of the national GHG reduction target, through energy conservation, waste management, and water efficiency measures. Adjusted targets, including an 18.50% reduction in the energy sector (107 hotels), a 21.00% reduction in waste (121 hotels), and a 2.50% reduction in wastewater (14 hotels), could enable large hotels to achieve a reduction of 83,880 tCO₂eq, allowing them to fully meet their assigned reduction responsibilities. Furthermore, this would contribute 0.76% to the national target. This study demonstrates how integrating measurable components into the STG framework can enhance the tourism sector’s role in achieving national climate goals and promoting sustainable practices.

Thailand has formulated her climate change policy and updated relevant plans and policies to align with the goal of achieving carbon neutrality and net zero GHG emissions. This study investigates the optimal level of GHG mitigation in Thailand, taking into account the marginal abatement cost (MAC) and social cost of carbon (SCC). It evaluates how energy efficiency and renewable energy technologies influence GHG reduction in the power and industrial sector and illustrates policy recommendations that align with the 2020 to 2050 policy and plan period. The findings indicate that there may be instances where GHG mitigation potential is insufficient to reach the national mile-stone. In such cases, it becomes imperative to leverage all technologies within the marginal abatement cost curve (MACC) and also utilization of the social cost of carbon for policy decision making and meeting the desired goals. In certain scenarios, the adoption of additional technologies or measures may be necessary, such as flexible power generation and deploying carbon capture and storage or hydrogen which are high-cost technologies. Furthermore, preparations should be made for multiple levels of climate change policies and plans beyond 2030.
