Carbon footprinting is a tool for firms to determine the total greenhouse gas (GHG) emissions associated with their supply chain or with a unit of final product or service. Carbon footprinting typically aims to identify where best to invest in emission reduction efforts, and/or to determine the proportion of total emissions that an individual firm is accountable for, whether financially and/or ...

Emissions of carbon dioxide are predicted to increase this century leading to increases in the concentrations of carbon dioxide in the atmosphere. While there is still much debate on the effects of increased CO2 levels on global climate, many scientists agree that the projected increases could have a profound effect on the environment. Most of the anthropogenic emissions of carbon dioxide resul...

Introduction: Greenhouse gas (GHG) emissions have caused environmental effects. Food production is one of the sources of GHGs. This study aimed to suggest dietary scenarios for decreasing GHG emissions. Materials and Methods: GHG emissions in the target population of Urmia city, Northwest Iran, were investigated using a modeling approach. Three dietary scenarios were modeled and analyzed to ev...

China was responsible for 25 per cent of global carbon dioxide emissions in 2012 (Liu 2015). This followed the passing of key milestones in the previous decade. From 2007, China’s per capita carbon dioxide emissions exceeded the world average and it has become the world’s largest contributor to annual carbon dioxide emissions, with the burning of fossil fuels and cement production being two imp...

Carbon pricing (taxes) and carbon emissions trading are two globally practiced carbon regulatory policy schemes. This paper presents an analytical supply chain planning model that can be used to examine the supply chain performance at the tactical/operational planning level under these two policy schemes. Model implementation and analyses are completed using actual data from a company operating...

the increase of greenhouse gases (ghg) in which co2 emissions constitute the principal component, is of major environmental problems of all societies. economic growth impels intensive use of resources and as a result, more residues and wastes thrown in the nature that could lead to environmental degradation. this article tries to trace the eventual relationship between trade openness and enviro...

Climate change will affect climate-carbon cycle feedbacks such that permissible emissions to achieve stabilisation will need to be substantially lower than hereto expected. This is especially true for higher stabilisation levels with reductions to total permissible emissions of over 30%. There is an “optimal pathway” to each stabilisation level, defined as that allowing maximum permissible emis...

This research is the first attempt of a carbon emission investigation of tourism-based farms. A total of 36 cases were investigated. The result reveals that each tourist returns an average revenue of 28.6 USD and generates an average 10.9 kg-CO2eq per visit of carbon emissions. The average carbon emission density for each land area is 8.2 t/ha·year and is 245 kg/m2·year for each floor area. It ...

BACKGROUND The healthcare sector is a significant contributor to global carbon emissions, in part due to extensive travelling by patients and health workers. OBJECTIVES To evaluate the potential of telemedicine services based on videoconferencing technology to reduce travelling and thus carbon emissions in the healthcare sector. METHODS A life cycle inventory was performed to evaluate the c...
