We present a 60-year record of the stable isotopes of atmospheric carbon monoxide (CO) from firn air samples collected under the framework of the North Greenland Eemian Ice Drilling (NEEM) project. CO concentration, δ 13C, and δ 18O of CO were measured by ...
Today’s world faces a large problem which is global warming. Glaciers melting see, and oceans water level rising, and droughts in Africa. According to [1] there are seven main sources of CO2 emissions from fossil fuels combustion: 1. Solid fuels (e.g. coal ...
Studies on preferences for environmental quality usually posit that price and income explain most of the observed choices. However, we argue that conceptions of social norms and the common good are equally important when analyzing environmental voting outc ...
In this study archaeology, history and palaeoecology (modern and fossil data sets of pollen and non-pollen palynomorphs) were used to reconstruct small-scale pastoral activities in the Pyrenees Mountain during the last two millennia. Modern pollen assembla ...
The interest in developing biofuels has rapidly increased during the last decades followed by a strong controversy about their sustainability. Diverting a large amount of land from agriculture to fuels, impacting forests and grasslands, loss of biodiversit ...
Increased worldwide concern about the sustainability of large-scale production of liquid biofuels for transport has led certain governments and institutions to start developing sustainability standards in order to assess the environmental and social perfor ...
Incident solar radiation is the most fundamental of the sustainable energy sources, being at the origin of all others - wind and wave, biomass and even fossil fuels which represent stored solar energy over a geological time scale. Only nuclear and geotherm ...

As energy plays a central role in the world development, it represents as well a major challenge for sustainable development. Today, more than 80% of the primary energy consumption is based on fossil fuels and the share is likely to remain high in the futu ...
The improvement of the energetic behavior of buildings has turned into a major issue due to the high level of energy consumption. One of the main objectives of the current French legislation, thanks to the definition of a global performance indicator (expr ...
