Kupang as a city with a strategic geographic location flanked by two states East Timor and Australia, making this city prospect of progress towards sectors of the economy that overgrew in a row of towns and first outer zone. With the agenda of SDGs post-MDGs provide consequence support for a local authority to oversee the activities support the SDGs include collaboration globally between stakeholders with some of the significant components support such as sustainable urban, sustainable energy, sustainable natural resources coupled with mitigation and adaptation to climate change. This study aims to obtain an integrated model in scope on greenhouse gas emissions (GHG) reduction due to the activities of urban economic sectors in Kupang and the transformation towards a sustainable energy structure under the SDGs. The model results are explained the share of household mix electricity consumption supplied under GHG constraint (n)=0%~20% in Kupang shows the percentage of electricity consumption of renewable energy (RE) increases rapidly after n=14%~18% such as at n=12% share of consumption supplied by ET only 17.69%, for n=14%~18%, electricity supply mix increased dramatically between 27.67%~28.73% of the total percentage of electricity consumption compared to the electricity supply of diesel. At n =19%~20% to 25%~26% of total ratio electricity supply, while compared with the total diesel consumption with level n=0%~12% the ratio is approximately 16.69%~18.89%. Therefore, the best constraints around n 14%~18%, which gives the most significant allocation of resources ET power supply. In addition to the alignment of the division of the energy supply mix above, GHG emissions decreased dramatically Kupang comparable with GHG constraints 14,38Mt ~ 0.011,62Mt CO2e with a balanced distribution of added value for each sector. This study supports not only zero emissions and sustainable City, also provides a reference inventory of GHG emissions refers to RAD-GRK.

General population in Korea are under a great risk with continual exposure to highly concentrated particulate matter (PM). Even with successive industrial economy, Korea also needs to confront the increasing social cost due to frequencies of the days when PM levels are highly exceeding the recommended WHO levels. The PM concentration levels in Korea are highest among OECD countries and raised great concern how to resolve and clean atmospheric environment. Korean government announced ‘The 2nd Atmospheric Environment Comprehensive Plan’ in April 2016. This updated program is aim to reduce the air pollution over 50 percent, however the PM problems are more intensified and citizens continue to appeal for better policy to protect the national health. The objective of this study is to address current problems experiencing in Korea and classify the specialists’ perception with respect to the policies, impairment cases, and management direction related to PM. Specialists in Korea are deeply involved in promoting government policies, so that it is valuable to gather their perceptions and comments. This study uses Q-methodology, which is a method to analyze the subjectivity of human mind. Categorizing human subjectivity is helpful to create human’s common interests and to understand the differences between their positions. In this respect, representative thoughts and perceptions of the specialists are categorized with composed statements and literatures. The specialist interviews are employed with the institution researchers, academic professors, and officials in environmental field. The PQMethod program is used to analyze the data. The results show that how the specialists’ perceptions can be categorized by PM classifications and their relationship with the policy to reduce the PM levels in Korea.

Langfang City is an important city within the strategic deployment of Beijing-Tianjin-Hebei coordinated development, but it is also one of the cities with a serious lack of water resources in Hebei Province even the whole country. With the rapid development of social economy, Water shortages and pollution have gradually become an important issue that will restrict the future development of the city. Utilization of reclaimed water is an efficient wan to ease the water environment constraints and ensure economic population growth in water resources needs. Based on the above practical problems, this research builds a water resource-environment-economy comprehensive evaluation model, and using LINGO programming software to achieve simulation. The model is based on the input-output model, Including water cycle model, pollutant flow model and socio-economic model three sub-models. The simulation period of the comprehensive evaluation model is 2015-2025, the goal is to achieve maximum economic growth on the basis of improved water environment. This study utilized the dynamic linear optimization model to analyze the potential of using reclaimed water to accomplish local water environment management and sustainable development plan while exploring the applicable approaches. This study indicates that the constructed water environment management system can be effective and easily adopted to assess water resources and environment while improving the trade-off between economic and environment development, as well as formulate regional development plan.
