Повний текст джерелаThe UK faces the joint economic policy challenges of raising productivity and tackling climate change. This report challenges prevailing narrow market-based views of productivity, by examining the £4bn UK early stage Cleantech innovation finance market. We find that Cleantech innovation is frequently capital intensive and long horizon (5-10+ years), measured by shorterterm technology readiness level (TRL) and intellectual property (IP) progression. Longer-term sustainable productivity impacts remain little understood and, where applied, narrowly relate to customer adoption. This leads to Cleantech environmental impact investor logics that primarily relate to end user financial value (customer sales). There is little consideration for non-market values from, for example, circular economy (CE) and wider environmental spillover impacts (e.g. supply chains). Whilst few Cleantechs currently successfully commercialise, a small proportion exhibit high employment and sales growth and global environmental impact. Improved understanding of the broader environmental impacts of Cleantechs, through the adoption of environmental impact metrics (EIMs) can (i) add to a more holistic notion of productivity and (ii) improve the efficiency of the finance escalator, enabling more Cleantechs to contribute significantly to establishing the UK as a globally leading low carbon economy.

Повний текст джерелаEn av vår tids största utmaningar är de pågående klimatförändringarna. Forskning visar att det till allra största del är vi människor som genom våra utsläpp av växthusgaser är ansvariga för den globala uppvärmningen och de problem som den för med sig. För att reducera utsläppen av växthusgaser och uppnå de internationella utsläppsmålen krävs delvis insatser på individnivå. Vissa människor bryr sig mycket om klimatet och försöker göra allt i sin makt för att minska sin egen klimatpåverkan, andra vill göra något men vet inte vad och vissa bryr sig inte alls. Denna studie syftar till att ge en djupare förståelse för hur man kan påverka människor att leva mer klimatsmart genom att identifiera faktorer som påverkar miljövänliga beteenden i både positiv och negativ riktning. Studien genomfördes genom en kvalitativ fallstudie där datainsamlingen gjordes genom personliga intervjuer med invånare i Luleå kommun. Studiens resultat visar att kunskap har en stark koppling till en individs beteenden. Det är viktigt att de insatser man gör till förmån för klimatet känns betydelsefulla. Många har en vilja att göra mer för klimatet men hindras av kontextuella faktorer, till största del handlar det om tidsaspekten. Förutom de faktorer som identifierades i det teoretiska ramverket framkom även ytterligare orsaker till varför individer beter sig miljövänligt: hälsa, ekonomi, etik, sparsamhet samt att värna om framtida generationer. Genom att identifiera dessa faktorer samt få förklarat hur de påverkar individen kan studien bidra med information till beslutsfattare exempelvis inom kommuner för att de ska kunna anpassa sitt omställningsarbete till medborgarna i kommunen. Studiens rekommendationer för kommuner är att de bör bistå med tydlig information till invånarna, både när det gäller vilka mål de siktar till att uppnå samt vad som konkret krävs för att uppfylla dessa. Kommunen bör också göra det lättare att välja miljövänliga alternativ, marknadsföra såväl klimatnyttan men även andra skäl till ett visst beteende eftersom att många motiveras mer av andra fördelar än klimatnytta. Samt dela med sig av resultat i klimatarbetet för att göra medborgarna delaktiga samt sprida motivation att arbeta vidare.

Повний текст джерелаThe aim of the presented research is to formulate industrially viable low carbon footprint concrete (< 150 kg.eq.CO2/m³). First, high substitution of clinker (65 % to 70 %) by metakaolin and limestone has been investigated to reduce the concrete’s carbon footprint. Then, granular packing compacity has been optimized with the Compressible Packing Model to reduce the required paste volume.High water content reduction (with adapted admixture content) and a thermal treatment have been applied to approach an Ordinary Portland Cement concrete’s performances. Compressive strength of superior to 14 MPa at 8 hours and strength classes of C25/30 and C40/50 have been reached. Also, through a performance approach, durability classes XC2 or XC4, XS3e and XS3m have been validated. The developed low carbon solutions were used to produce walls with integrated formwork at the industrial scale

With the emergce of environment problems, such as global warming, greenhouse effect and extreme climate, the problems of carbon emissions have become an important international issue. Obviously, the carbon emissions of buildings sector is the most in global greenhouse gas emissions by economic sectors. Cutting carbon dioxide emissions of buildings become more critical for carbon reduction. This study create an educational board game to spread the sustainable environment protection. The design concept of the game is based on Building Carbon Footprint Evaluation Method, which proposed by Low Carbon Building Alliance (LCBA). The game create a model to simulate a house construction processed by purchasing equipment and choosing the building materials, and reducing carbon footprint by energy-efficient technologies design afterwards to achieve the purpose of low carbon building. In order to exam the result of this instructional game, there are two experiments. These results show that participants’ awareness of low carbon building has been improved. Secondly, the participants purchase more energy-saving devices or more green building materials are helpful for cutting carbon footprint of building.

With the rising concern on the deterioration of climate change, how to educate general public to reduce their carbon footprints become more and more important. Currently, governments of every country focus not just on controlling the main emissions sources, but also try to enhance the efficiency of carbon reduction through the development of low carbon communities. Hence, a suitable carbon footprint calculator play a crucial role in educating general public to understand their own carbon emissions and to further change their living behaviors. In Taiwan, although several carbon footprint calculators have been developed, none of them is adequate in terms of functions and completeness of the database. Therefore, to develop a carbon footprint calculator framework conforming Taiwanese living style and with completeness becomes the goal of this study. After analyzing various carbon footprint calculators, an evaluating hierarchy for Taiwan’s carbon footprint calculator was proposed. In order to ensure the effectiveness of the hierarchy, this study applied the Fuzzy Delphi Method to collected experts’ opinions on the framework. After two rounds of FDM questionnaires, the framework of carbon footprint calculator to be used in Taiwan was finalized. The proposed carbon footprint calculator framework consists of 5 dimensions (including household, transportation, food, commercial goods/services and green behaviors) and 21 indicators. In addition, through collecting and analyzing the carbon emission coefficients, this study discovered that most of carbon emission coefficients for calculating carbon footprints are missing in Taiwan. It is suggested that in order to strive to the low carbon society, a database which consists of accurate and complete carbon emission coefficients should be established in the future.

The carbon emissions by travel behavior will seriously influence the change of the world’s climate. In response to sustainable development of the future environment, it is indeed and urgent important to develop low-carbon tourism. The main purposes of this study were to find out factors influencing the development of low-carbon tourism of Taijiang National Park. We try to figure out the environmental unfriendly factors through reviewing the routes of low-carbon tourism in the Tai Jiang National Park. Meanwhile, ecological footprint, including ecological footprint transport (EFT), ecological footprint accommodation (EFA), ecological footprint activities (EFAC) and ecological footprint food and fiber consumption (EFFFC), are applied to analysis the consumption of resources, carbon footprint transport (CFT), carbon footprint food (CFF), carbon footprint accommodation (CFA) and carbon footprint activities (CFAC) for the years 2010 to 2012. We expect to approach the appropriate development of low-carbon tourism methods in Taijiang National Park. The outcomes of reviewing the routes of low-carbon tourism in the Taijiang National Park are as follows: 1.The percentage of lodging at the Qigu District is less than 15%, it reveals that most of visitors stay at far away from the Qigu District 2. The catering business is not satisfied by visitors for there are only 19 restaurants nearby the Taijiang National Park. 3. The transportation is not good enough both at the number of runs and stops. The outcomes show that the routes of low-carbon tourism in the Taijiang National Park is not keeping with low-carbon tourism and resulting in increased CO2 of transport and Accommodation. The results of this research show that the annual ecological footprint of tourism, from 2010 to 2012, is between 10.29 and 14.25 (hectare/person) in Taijiang National Park. Moreover, the annual carbon footprint of tourism is between 14.72 and 15.63 (kg CO2e/person). Analyzing data from both the ecological footprint and the carbon footprint, we observe that transportation seems the most influential factor with the average value 52.40% and55.88% respectively. These results indicate that it consumes petrochemical energy mainly for the tourism in Taijiang National Park. However, the petrochemical energy footprint in ecology is one of the most important factor concerning global warming and ecological threat. With the analysis and discussion of this research, we can conclude and provide some practical suggestions for developing low-carbon tourism of the Taijiang National Park in the future.

Due to rising awareness of environmental protection, more and more consumers paid their attention to the lower environmental impact product development under the same features and conditions. Many companies begin to perform the environmental impact assessment and get the certification for their products in order to enhance their brand value. However, this environmental assessment process is generally implemented only when the products are designed and mass produced. It is too late for the designers to change their product design when they found the product may have higher environmental impacts. The reason is that it will cost a lot of efforts and costs to perform the change. In this research, the products’ environmental impacts are provided and analyzed during the design stage based on the previous certified products. In order to solve the confiscation of carbon emission and cost problems, a multi-objective decision making method, step method. Finally, a case study is applied for the demonstration of the results.

Abstract The environmental issues about global warming needs whole world''s people working together to solve the climate change. The number of domestic visitor is increasing, the needs for the transportation, consumption and tourists behavior may caused the increased of the total emissions and carbon dioxide, therefore, it is necessary for people to change their travel behavior and care more the environment. From the Environmental behavior studies, the scholars believed that the theory of planned behavior provides researchers the measurement to predict the tourist activities and the behavior that may affect the environment thus visitors need to be informed and guidance which behavior to avoid. The purposes of this study ere (1) Using the Theory of Planned Behavior as visitors construct and low-carbon travel behavior as structural model and examination models of various beliefs and attitudes, subjective norms and perceived behavior control to examine low-carbon travel behavior intentions; (2) To compare the carbon footprints of different individuals in the structural model if there are significant differences; (3) Individual attribute of visitors in the model variables if there are significant differences. In this study the questionnaire based on Ajzen’ theory of planned behavior, data were collected at Taipei, Pinglin Township in the low carbon tourist destination, for four days on May 30, 31 and June 6, 7 2009, survey were conducted using random sampling on site locations to visitors in the areas, from a total of 415 questionnaires, resulting a total of 327 usable questionnaires with response rate of 78.80%. In this study, first, descriptive analysis were conducted to described the individual attribute of visitors and second, structural equation analysis (SEM) was conducted to examine potential effect of low-carbon behavior intention model on latent variable and to compare the differences of the carbon footprints in the structure of the model and finally, t test analysis, one way ANOVA analysis of individual attribute from different tourist to test the significant differences. In this study the original model were tested and adjusted resulting revised model and the final revised model was acceptable to obtain as indicators, the results showed (1) The attitude of the low-carbon travel behavior intentions has highest significantly affect, followed by perceived behavioral control, and attitude toward the behavior; while the beliefs of the attitude, perceived behavior control and the subjective norms, the effects was also high, the indirect impact on behavioral intention resulting medium-low effect. (2) Visitors’ carbon footprint were divided by the Mean into two categories, low-carbon footprint and high-carbon footprint, for low-carbon footprint the effects in behavior intention model is from perceived behavioral control, subjective norms and attitudes; and for the high carbon footprint the highest effects are behavior, subjective norms and their perceived behavior control had no effect; the belief in the two categories of visitors, from attitude, perceived behavioral control, subjective norms, the effect were higher, generally, high-carbon footprint is lower and the low-carbon footprint is higher. (3) The ANOVA analysis for the differences between the individual attributes of tourists, age, education level, the latent variable of traveling in a low-carbon travel behavior patterns, shows significant differences in different situations. This study suggests that in the future need implementation of the rule, policy and education of low-carbon travel behavior, should more emphasis on improving the visitors’ attitudes and perceived behavior control, subjective norms, supplemented, thereby increasing the intention of low-carbon travel behavior; the Government can also hold more low-carbon tourism activities in order to increase the tourists’ participation and consequently improve the general effectiveness; so the carbon footprint of tourist in daily life and individual attributes have assistance and choice to engage in the tourism activities. Because of the limitation of this study recommended that future research could explore the actual behavior of tourists or comparison of cross-regional differences.

The aim of this study is to produce bioethanol from Kappaphycus alvarezii with low cost and low carbon footprint technology. Thirteen marine bacteria with agarase activity were isolated from decomposed algae, thread seaweed, decomposed K. alvarezii, and sea water in Keelung, Taiwan. Three strain with most prominent agarase activity were W208, W518, and W619. Based on result of some biochemical tests, this isolate was pre-identified as Pseudomonas sp. Crude enzymes were produced by Pseudomonas vesicularis MA103 (MA103), Aeromonas salmonicida MAEF108 (MAEF108), and isolate W518 (W518). The highest enzyme activity of strain MA103 was its amylase activity at 3 days of incubation (5.01 U) in AM-Kap-A [half strength artificial sea water medium added with 0.3% (w/v) K. alvarezii hydrolyzed by 0.2 N HCl at 121oC for 20 min], strain MAEF108 was its agarase activity at 3 d incubation (2.85 U) in AM-Kap-P [half strength artificial sea water medium added with 0.3% (w/v) K. alvarezii powder], and strain W518 was its amylase activity at 3 days of incubation (1.64 U) in AM-Kap-AP [half strength artificial sea water added with 0.15% (w/v) K. alvarezii powder and 0.15% (w/v) K. alvarezii hydrolyzed by 0.2 N HCl at 121oC for 20 min]. The most effective acid hydrolysis condition was decided based on the amount of reducing sugar and electricity consumption ratio. The highest ratio was 40.16 mg/mL reducing sugar per kWh electricity, the most effective hydrolysis condition was using 0.4 N HCl 121oC for 0.5 h. Ethanol production by procedure I [5% (w/v) biomass, 4,560 U cellulase, 7,333 U amylase, used K. alvarezii-induced commercial Modified Marine Broth (MMB-Kap) as marine bacteria crude enzymes inducer] resulted in 34.00 g ethanol per 100 g K. alvarezii ethanol yield, but production cost was high. In order to lower bioethanol production cost, commercial enzyme usage was lowered. In procedure II-1-a, lower cellulase enzymes amount (760 U) was used, but biomass loading was increased [10% (w/v) biomass]. This procedure yielded 12.88 g ethanol per 100 g K. alvarezii powder. To further lower the cost, in procedure II-4-a which was the development of procedure II-1-a used AM-Kap-P to replace MMB-Kap for marine bacteria crude enzymes inducer, this procedure yielded 11.68 g ethanol per 100 g K. alvarezii powder. Fermentation of K. alvarezii hydrolysate with different acid concentration showed 0.2 N HCl, yielded 9.98 % (w/w) ethanol. Fermentation of K. alvarezii hydrolyzed with different biomass loading level showed 5% (w/v) biomass yielded 14.91 % (w/w) ethanol. The fermentation procedure VI-2 where cellulase and marine bacteria crude enzymes was added together and hydrolyzed at 37oC for 4 d yielded in 23.20 g ethanol per 100 g dried K. alvarezii. K. alvarezii hydrolysate for fed-batch fermentation was prepared as in procedure VI-2. The ethanol concentration was 1.59% (v/v) and ethanol yield was 10.55%, obtained at day-9 of fermentation. TLC and HPLC analysis showed that acid hydrolysis was able to hydrolyze K. alvarezii PSs to become galactose for yeasts fermentation. LCA analysis from K. alvarezii cultivation to ethanol production was calculated for K. alvarezii bioethanol production through procedure I, II-1-a, and VI-2. Compared to procedure I, the changes in biomass loading, HCl concentration, commercial cellulase, and crude enzymes in procedure II-1-a and VI-2 lowered the cost of production by 50% and 80%, respectively. Compared to procedure I (4.20 kg CO2/L), the amount of CO2 released increased for procedure II-1-a by 122% (9.35 kg CO2/L) and lowered the amount of CO2 released for procedure VI-2 by 30% (2.95 kg CO2/L). The amount of CO2 sequestered by seaweed during cultivation was higher than ethanol production process by 165% and 48% for procedure II-1-a and VI-2, respectively.

Повний текст джерелаNowadays, companies increase their competitive advantage by reducing their environmental impact. Correspondingly, Norwegian fertilizer company Yara International plans to improve its competitiveness through low carbon footprints. In order to conduct the best possible strategy for Yara to do so, a thorough understanding of the sustainability of Yara’s operational context, i.e. the food value chain, is required. Therefore, this project mapped the sustainability developments in the chain and their impact on both the agricultural industry and Yara’s competitiveness. The same type of analysis was carried out on the influencers alongside the chain. Consequently, several strategic recommendations for Yara were conducted.
