Over the last few years, the fight against climate change has
become one of the main topics of international debate, and is now
identified as one of the greatest challenges humanity has ever faced.
The main cause of climate change has been identified as the emission
of greenhouse gases (GHG) connected to human activities [1].
The international community, in response to this phenomenon,
has started several initiatives leading to the drafting of the Kyoto
Protocol in 1997 [2]. The protocol involves both industrialized and
developing countries with market economies, and aims to reduce
GHG emissions on a global scale. Together with the international
community’s increased attention on this matter, consumer behavior
has begun to change: consumers have started to assess the environmental
impacts of the products and services they buy [3–5].
As a matter of fact, enterprises now play a key role in the
achievement of GHG reduction goals such as in European emission
trading, in which enterprises belonging to specific industrial areas
have to follow legislative obligations that aim to reduce GHG
emissions [6]. Furthermore, as confirmed by the European
Commission, in the very near future many companies in different
areas will become involved in achieving the abovementioned
objectives [7].
