important, but only attends to intergenerational distribution and
doesn’t capture political acceptability.
4. Institutional feasibility – The extent to which a policy may be seen as
legitimate, accepted, adopted and implemented. Economists
traditionally evaluate policy under ideal theoretical conditions,
however these are rarely met in practice; political realities have to be
taken into account. The decision-making style of each nation or the
institutional familiarity that may make certain policies more popular
are factors to be taken into account.
Even if a policy has received political support, it may be difficult to
implement under certain bureaucratic structures.
2 Proposals for international climate change agreements
A variety of approaches have been proposed for future international climate
policy post 2012. Summaries are provided in Höhne, 2003; Aldy, 2003;
Bodansky, 2004; Kameyama, 2004; Blok et al., 2005; Philibert, 2005; Höhne, 2006;
Höhne, 2007; Kameyama, 2007; and Gupta et al., 2007.
This section provides an overview and assessment of several approaches and
issues that have been proposed. Some of the presented ideas cover a complete
future regime on climate while others only present ideas on specific issues. The
list of proposals is grouped around the following themes (Gupta et al., 2007):
• National emission targets and international emissions trading
- Alternative target approaches
- Description of the approaches to future commitments
