There are diverse views about how to sustain a safe and coherent relationship between humanity
and nature. Main distinctions center around the two following connected questions of sustainability:
“Is natural capital substitutable to human-made capital or not?” and – if substitutable –
“What is the extent of this substitution?” One argument is that increasing income will eventually
lead to a decline in human related ecological degradation (environmental Kuznets curve hypothesis)
(Grossman and Krueger, 1991). Main basis for this idea is the assumption that technologic
improvements will make us more efficient in using natural resources and human made capital will
be able to replace natural capital in most cases (Grossman and Krueger, 1995). Proponents usually
justify this idea by claiming that people will be more demanding about environmental quality
with increased wealth and put pressure on politicians and adjust behavior in markets towards that
demand (Beckerman, 1992). Although the theory may explain the success of high developed
countries in curbing air pollution, as several empirical studies show, there has not been strong
evidence of such a trend between CO2 and GDP as is implied in the environmental Kuznets
curve (Yandle et al., 2002; Stern, 2014). It may be possible to observe a decoupling between
increasing income and carbon dioxide emissions in some highly developed countries; however,
this does not necessarily mean that there is really a decoupling at the global level (see Chapter
10 for a discussion of the link between carbon emissions and energy use). What lies behind the
carbon reduction success of some developed countries may be their ability to transfer the carbonintensive
production activities to other countries. Therefore, when a country is becoming more
environmentally efficient on paper, it may be due to this shift in the structure of the economy.
This does not guarantee a decline in total global emission budget.
