As tradeable permit programmes mature, two inter-related issues are becoming more critical in creating viable responses to a long-term, highly uncertain environmental problem such as climate change. First, we need to update policies in response to new information; and second, we need to design...

Experimental methods have recently been used to evaluate environmental policy instruments, in particular – and most suitably, it seems – emissions trading programs of various designs. Some studies have focused on domestic emissions trading programs, while others have focused on international...

Agriculture and forestry play an important role in emitting and storing greenhouse gases. For an efficient and cost-effective climate policy it is therefore important to explicitly include land use, land use change, and forestry (LULUCF) in economyclimate models. This paper gives an overview and...

Afforestation and reforestation (AR) projects in the Clean Development Mechanism are able to create emission permits that can be accounted against the industrialized countries' commitments for limiting their greenhouse gas emissions, as agreed under the Kyoto Protocol. The discussion of how to...

International climate negotiations have specified that projects under the Clean Development Mechanism (CDM) should not lead to a „diversion“ of official development assistance (ODA). It is however unchallenged that ODA can be used in capacity building for the CDM. Diversion can be...

The „first track“ of Joint Implementation under the Kyoto Protocol gives host and investor countries total freedom in choosing a baseline for a project reducing or sequestering greenhouse gases. This is due to the fact that an overly generous granting of emission credits leads to a...

Greenhouse gas emission trading has become more and more important in the context of climate change. Recently, a discussion on trading on entity (i.e. company) level has started. Emitters likely to be obliged to participate have argued for an initial allocation of the emission rights free of...

Greenhouse gas (GHG) removals by afforestation and reforestation project activities under the Kyoto Protocol's Clean Development Mechanism (CDM) are vulnerable to a variety of risks and uncertainties, resulting in the partial or total reversal of such removals. Hence, GHG removals from these...

The Clean Development Mechanism (CDM) under the Kyoto Protocol to the UN Framework Convention on Climate Change (UNFCCC) enables industrialized countries to meet a part of their emission reduction requirements through purchase of emission reduction credits from projects in developing countries....

After Future climate policy regimes may be based on the Kyoto-Protocol or on other policy instruments such as carbon-taxes. Any effective regime based on the Protocol requires the determination of the concrete contributions by each Party. This involves namely the time of contribution and the...
