Abstract:Energy efficiency is one of the most practical ways for China to simultaneously tackle environmental issues and achieve sustainable development. However, the issue of inadequate capital inflows is a bottleneck in energy efficiency projects, especially for small and medium-sized enterprises (SMEs). This study focuses on the complicated financial barriers to effectively promoting such projects for SMEs. A hybrid framework was proposed to recognize the most obvious financing barriers under uncertain circumstances. Potential barriers were collected firstly to build an index system, including the five dimensions of "policy and regulation", "economic market", "financial institutions", "behavior" and "economic non-market". Then, this paper introduced a novel way to combine a fuzzy Delphi and a fuzzy decision making trial and evaluation laboratory (DEMATEL) method. The fuzzy Delphi method was applied to extract significant factors from potential barriers. To analyze a series of causal relationships, the fuzzy DEMATEL approach was employed. Moreover, triangular fuzzy numbers (TFNs) are used firstly to express vague linguistic ratings in the proposed framework. Based on the experts' opinions, seventeen significant factors were chosen to assemble a final evaluation system. Eleven key barriers were identified by analyzing cause-effect relations, including "slight fiscal incentives", "inadequate energy market trading mechanisms", "a low priority of energy saving issues", etc. The key barriers affiliated with "market" and "policy and regulation" are much more important than the others. Except for B11 and B53, the others are the original factors. Finally, we listed relevant suggested measures to help SMEs, government departments and financial institutions overcome the key barriers.

“…Thus, various control measures such as appropriate land use planning and creating buffer zones for sensitive receptors; installation of noise barriers for hospitals, schools, colleges, old age homes; enforcement of maximum speed limit for heavy vehicles in residential areas; development of poro-elastic road surfaces for traffic noise control; establishment of no honking zones especially for residential and silence zones and traffic management can be instrumental in ambient noise control. However, the best practicable and economical option (BPEO) may be executed considering all these possible noise abatement alternatives [29][30][31][32][33][34][35][36][37] for each of these sites under consideration individually.…”

We describe the diversified National Ambient Noise Monitoring Network (NANMN) set up across 7 major cities of India and covering 70 stations for continuous noise monitoring throughout the year. The annual average L day (06-22 h) and L night (22-06 h) values observed in 2015 for these 70 locations are described. Of these, 25 locations are in commercial zones, 12 in industrial, 16 in residential and 17 in silence zones. Each city has 10 noise monitoring stations installed for analysing environmental noise pollution levels round the clock (24  365 h). The long-term noise monitoring shows that ambient noise levels are very high compared to the recommended standards for some sites and thus noise abatement measures are essentially required for controlling these levels. The present study is focused on evaluation, analysis and reporting of environmental noise pollution in seven major cities of India and is instrumental in planning for the noise abatement measures for controlling noise pollution in these cities. Such a noise monitoring network established in India is unique and one of the largest noise monitoring networks of its kind across the globe. Keywords: Day equivalent level, day-night average sound level, National Ambient Noise Monitoring Network, night equivalent level.NOISE pollution has become a serious concern over the past several years in India. With growing vehicular population and urbanization, it is imperative to monitor the ambient noise levels and devise suitable measures for control to avoid health hazards and annoyance faced by the community. The evidence for effects of environmental noise on health is strongest for annoyance, sleep and cognitive performance in adults and children. The occupational noise exposure also shows some association with high blood pressure 1 . There have been many such studies conducted so far on the noise exposure and correlation with human blood pressure 2-5 . Meta-analyses have been carried out to derive the exposure-response relationships that can be used for quantitative health impact assessments 6 . The meta analysis of 24 cross-sectional studies on the relationship between road traffic noise and prevalence of hypertension reported an odds ratio (OR) of 1.07 (95% confidence interval (CI) = 1.02-1.12, P < 0.05) per 10 dB increase of 16 h day-time average road traffic noise level (L Aeq,16 h ) in the range of <50 to >75 dB (refs 7, 8). In India, there have been limited studies carried out on correlating the effect of noise on human health. A recent study provides evidence that road traffic noise is a serious cause of concern 9 . The study infers that association between transportation noise exposure and cardiovascular disease is evident, but not at significant level. A similar study suggests epidemiological evidence that exposure to road traffic noise of

“…Educative and innovative programmes such as organizing 'Noise Awareness Campaigns', 'Dhwani Pradushan Niyantran Diwas' (noise pollution control day) and integrating 'Noise Pollution Control Mission' as a part of the ongoing 'Swatch Bharat Mission' introduced by the Government of India shall be indispensable in controlling noise pollution in India. Socio-acoustic surveys, noise impact assessment studies due to various noise sources, and noise monitoring during festival days should be conducted in parallel to quantify the noise impact and assessment of induced noise annoyance [56][57][58][59][60] .…”
