(2) Do existing estimates of the no-regret potential stand up to
are-evaluation within this framework? As a result of this analysis the
size of previous estimates for no-regret potentials may be modified - in
terms ofenergy savings or in financial terms. On the basis of these
findings, we will approach the overriding third research question: (3)
How large is the no-regret potential and what determines its size? The
following chapter will provide a fuller account of the debate on
no-regret potentials. This will be complemented by a detailed
theory-based definition of no- regret potentials in Chapter 2. The
thesis will focus mostly on the micro-level of analysis. But we will
also address the implications ofour findings for the analysis ofenergy
saving measures and policies at more aggregate levels, notably within a
feasibility study for adapting a model which represents the level of the
national economy. The debate on no-regret potentials- 1 origin, context,
issues The term "no-regret potentials" was coined during the debate on
climate change. It designates opportunities for the reduction of
greenhouse gas (GHG) emissions ". . . that are worth undertaking whether
or not there are climate-related reasons for doing so. " (IPCC 1996, p.
271). In the IPCC's Third Assessment Report (TAR), no- regret potentials
are increasingly equated with GHG emission reduction potentials at
negative (net) costs (lPCC 2001, p. 21).
