“…Case 2 and case 3 used the aqueous phase of bio-oil instead of natural gas to produce hydrogen, and the co-product hydrogen plays a crucial role in reducing PED and GWP of case 3. The reduction of GHG emissions will help alleviate a series of environmental and agricultural problems caused by the greenhouse effect and help countries to achieve the goal of carbon neutral (Sreekanth, 2016). For purpose of achieving the sustainable development of biofuel, the European Renewable Energy Directive (RED) proposes a 60% reduction in GHG emissions from cellulosic biofuel compared to conventional fossil fuels (Hennecke et al, 2013).…”

This study aimed to evaluate the environmental impact of 1000 kg h−1 wheat straw to produce biofuel via fast pyrolysis with three different hydrogen production processes by the life cycle assessment (LCA) based on Chinese Life Cycle Database (CLCD). The primary energy depletion (PED), global warming potential (GWP), abiotic depletion potential (ADP) and respiratory inorganics (RI) impact categories of 1 MJ biofuel produced were employed for comparison. In case 1, the hydrogen was derived from natural gas steam reforming, and all the bio-oil was hydrotreated to produce the biofuel. In case 2, a part of the aqueous phase was reformed to produce hydrogen, whereas the remaining bio-oil was hydrotreated to produce biofuel. In case 3, all the aqueous phase of bio-oil was reformed to produce hydrogen, a part of hydrogen generated by reforming was used to oil phase hydrotreated and the excess hydrogen was considered as a co-product. Our results show that the PED, GWP, ADP and RI of case 3 are 0.1355 MJ, −17.96 g CO2eq., 0.0338 g antimonyeq and 0.0461 g PM2.5eq.. Compared with conventional diesel, the PED, GWP, ADP and RI of case 3 were reduced by 89.81, 117.44, 1.74 and 85.03%, respectively. The results of sub-process contribution analysis and sensitivity analysis suggested that the electricity consumption for the bio-oil production has the maximal effect on the total PED, GWP and RI of case 3, whereas the amount of fertilizers in the biomass production sub-process has the maximal effect on the total ADP.

“…Enterprises need to follow the global climate change convention, use low-pollution equipment, and improve R&D technology to lower the operational risks faced by carbon reduction [1]. How to use industrial development policies to reduce greenhouse gas emissions, create green business opportunities and competitiveness was pointed out, and this has become the industry's highest priority for sustainable management [2]. Expansion in the scale of an enterprise's production and increased labor force are the key factors for the increase of greenhouse gas emissions [3].…”

Since the Paris Agreement came into effect in 2016, governments worldwide have established goals for future carbon emission reduction. Enterprises and governments have begun to pay attention to the management of carbon emission. This study explored the dynamic relationship between business growth and carbon emission performance by constructing and using a time series model to predict the trend of carbon emission. The time series method (ADF unit root test, cointegration test and VAR model etc.) was adopted to investigate 805 companies listed on the Taiwan Stock Exchange from 2012 to 2017 as the sample of this study. The carbon emission performance variables include: total carbon emission, annual increase of carbon emission, and annual increase rate of carbon emission. The business growth variables include: growth rate, stability of growth, and years of establishment. The results showed a long-term dynamic relationship between business growth and carbon emission performance. Therefore, using the time series method can assist enterprises in developing green strategies, strengthen carbon emission prediction and management capacities, reduce operating costs and risks, and actively achieve the ideal of sustainable development.

“…La energía en sus diferentes formas tiene un papel preponderante en las actividades diarias de los seres humanos, y por tanto es un componente importante de la actividad económica de un país. Sin embargo, su uso también presenta consecuencias negativas como el agotamiento de recursos, afectación al medio ambiente y emisión de gases de efecto invernadero; estas secuelas son marcadas en el caso de fuentes energéticas que usan combustibles de origen fósil [2].…”

Las proyecciones de crecimiento poblacional y económico en el Ecuador indican que la demanda de energía eléctrica mantendrá una tendencia creciente. Uno de los esquemas orientados a contribuir con la cobertura futura de la demanda energética es la autogeneración eléctrica, en la que los usuarios producen electricidad para satisfacer necesidades propias mediante generadores instalados en el propio punto de consumo. En este trabajo se presenta una metodología para proyectar el potencial de autogeneración con paneles fotovoltaicos instalados en las edificaciones del país. El espacio máximo disponible para la instalación de paneles es estimado tomando secciones del área propiamente construida de los sectores residencial, industrial, comercial, mixto y otros. La penetración de la autogeneración fotovoltaica es estimada entre los años 2013 y 2050, calculando la evolución de la demanda energética durante este período mediante el uso del software de planeación energética LEAP. Los resultados obtenidos son comparados con los de un escenario sin autogeneración. De acuerdo a los resultados obtenidos para el año 2050, alrededor de un 17% de la capacidad instalada estaría representada por sistemas de autogeneración fotovoltaica, cubriendo alrededor de 5,7% de la demanda de energía eléctrica total.
