Integrating Joint Implementation Projects for Energy Efficiency on the Built Environment with White Certificates in The Netherlands 总被引:2,自引:1,他引:1
V. Oikonomou W. van der Gaast 《Mitigation and Adaptation Strategies for Global Change》2008,13(1):61-85
In this paper we analyze policy interactions between two innovative climate and energy policy instruments, namely White Certificates
(WhC) and Joint Implementation (JI) that target at energy efficiency improvement and reductions of Greenhouse Gas (GHG) emissions.
We have selected The Netherlands and Bulgaria as a case study given that the former has a cumulated experience in energy efficiency
policies and the latter for a growing potential in JI projects as a host country. Based on a method of analyzing policy interactions,
we demonstrate how a possible design of such a scheme can take place and how it should function. A couple of parameters that
deserve attention are a baseline definition and a conversion rate for credits. Our basic finding is that an integrated scheme
is complementary and can assist substantially in achieving Dutch national United Nations Framework Convention on Climate Change
(UNFCCC) Kyoto Protocol targets. Dutch electricity and gas suppliers (parties that receive energy efficiency obligations)
can implement energy efficiency projects domestically and in other countries, hence reducing total abatement costs. Furthermore,
such a scheme can stimulate further energy efficiency actions from other stakeholders participating in energy markets. Based
on an ex-ante assessment, a carefully designed hybrid WhC and JI scheme appears to be effective in terms of targets, efficient,
generating positive impacts on markets and society, while uncertain in stimulating innovation.

Climate change combined with human activities poses significant risks to people’s livelihood especially in developing countries.
Adaptation at the community level is of crucial importance in enabling them to respond to the direct and indirect effects
of changes in climate. In a case study of fishing communities in Chilika lagoon, India, the focus is made on understanding
climate change adaptation at the community level and scaling it up into the policy perspective through application of Sustainable
Livelihood Approach. This article challenges the research and policy community to encourage the identification of locally
negative constraints and positive strengths toward climate resilient communities in rural areas.

Greenhouse gas mitigation in developing countries through technology transfer?: a survey of empirical evidence 总被引:1,自引:0,他引:1
Sonja Peterson 《Mitigation and Adaptation Strategies for Global Change》2008,13(3):283-305
While greenhouse gas (GHG) emissions are projected to rise primarily in the developing countries, the potential for developing
new GHG mitigation technologies exists primarily in the industrialized countries. It is thus important, not only for predictions
about future emission paths but also for climate change mitigation policies, to understand how the international diffusion
of such technologies takes place and how it affects the energy infrastructure and GHG emissions in developing countries. This
paper provides an overview of the channels through which these technologies diffuse and focuses on the empirical evidence
pertaining to the effects these technologies have on GHG emissions in developing countries.

The paper presents a number of ideas on how climate change policy implementation in developing countries can be supported
by alternative international cooperation mechanisms that are based on stakeholder interests and policy priorities including
broader economic and social development issues. It includes a brief review of current development policies, technological
research and promotion efforts, and climate change that demonstrates that mutual policy initiatives undertaken by governments
and the private sector actually have major positive impacts on climate change without being initiated by this global policy
concern. Furthermore a number of examples are given on how future development objectives in Brazil, China, and India jointly
can support economic and social goals and global climate change concerns if these goals are taken into consideration and supported
by international cooperative mechanisms. The paper proposes international cooperative mechanisms that can support the implementation
of integrated development and climate change policies. The mechanisms include an international sustainable development (SD)
and Climate Finance Mechanism (SDCFM), technology development and transition programmes, technology standards, and other measures.

Approaches to semi-synthetic minimal cells: a review 总被引:1,自引:0,他引:1
Following is a synthetic review on the minimal living cell, defined as an artificial or a semi-artificial cell having the
minimal and sufficient number of components to be considered alive. We describe concepts and experiments based on these constructions,
and we point out that an operational definition of minimal cell does not define a single species, but rather a broad family
of interrelated cell-like structures. The relevance of these researches, considering that the minimal cell should also correspond
to the early simple cell in the origin of life and early evolution, is also explained. In addition, we present detailed data
in relation to minimal genome, with observations cited by several authors who agree on setting the theoretical full-fledged
minimal genome to a figure between 200 and 300 genes. However, further theoretical assumptions may significantly reduce this
number (i.e. by eliminating ribosomal proteins and by limiting DNA and RNA polymerases to only a few, less specific molecular
species). Generally, the experimental approach to minimal cells consists in utilizing liposomes as cell models and in filling
them with genes/enzymes corresponding to minimal cellular functions. To date, a few research groups have successfully induced
the expression of single proteins, such as the green fluorescence protein, inside liposomes. Here, different approaches are
described and compared. Present constructs are still rather far from the minimal cell, and experimental as well as theoretical
difficulties opposing further reduction of complexity are discussed. While most of these minimal cell constructions may represent
relatively poor imitations of a modern full-fledged cell, further studies will begin precisely from these constructs. In conclusion,
we give a brief outline of the next possible steps on the road map to the minimal cell.

This article examines possibilities for linkage between the European Union Emissions Trading System (EU ETS) and Russia, with
a view to enhancing cooperation on a broader scale than the project-based approaches that have been tested thus far. Three
paths for possible EU-Russia linkage are presented by which the Russian Assigned Amount under the Kyoto Protocol can be greened
in order to stimulate emissions trading: 1. Joint implementation—reductions earned via individual projects in Russia; 2. Greened
allowances or green investment schemes; and 3. Linked cap-and-trade systems, in which a Russian domestic emissions trading
system would link with the European Union Emissions Trading System. The authors conclude that the third option, emissions
trading through linked domestic emissions trading systems, offers the best opportunities at the lowest transaction costs.
The authors discuss useful innovative instruments like call options and slip level arrangements on government-to-government
and business-to-business levels.

The double trade-off between adaptation and mitigation for sea level rise: an application of FUND 总被引:6,自引:2,他引:4
Richard S. J. Tol 《Mitigation and Adaptation Strategies for Global Change》2007,12(5):741-753
This paper studies the effects of adaptation and mitigation on the impacts of sea level rise. Without adaptation, the impact
of sea level rise would be substantial, almost wiping out entire countries by 2100, although the globally aggregate effect
is much smaller. Adaptation would reduce potential impacts by a factor 10–100. Adaptation would come at a minor cost compared
to the damage avoided. As adaptation depends on socio-economic status, the rank order of most vulnerable countries is different
than the rank order of most exposed countries. Because the momentum of sea level rise is so large, mitigation can reduce impacts
only to a limited extent. Stabilising carbon dioxide concentrations at 550 ppm would cut impacts in 2100 by about 10%. However,
the costs of emission reduction lower the avoided impacts by up to 25% (average 10%). This is partly due to the reduced availability
of resources for adaptation, and partly due to the increased sensitivity to wetland loss by adaptation.

This article discusses an approach for identification and evaluation of short-term greenhouse gas (GHG) emission reduction
options in firms. The approach is based on lessons learnt from a project using Participatory Integrated Assessment (PIA) and
builds on the idea that effective public climate policy for firms requires options that have support from stakeholders and
are practically feasible. Scenarios are used to provide a link with short-term policy developments and a model assists to
communicate quantitative effects of options to participating stakeholders. Our approach can be seen as a first step towards
a framework that meets the need for more systematic approaches to PIAs identifying effective public policies for short-term
GHG emission reduction options in firms. In order to identify effective options for non-carbon dioxide GHG emission reductions,
our approach has been applied to Dutch dairy farms, after which it has been refined. The case study suggests that our approach
can provide balance between practical, context specific issues and scientific-theoretical aspects, thereby avoiding common
pitfalls of participatory research projects to focus too much on either theory or practical issues.

Adaptation and mitigation as complementary tools for reducing the risk of climate impacts 总被引:2,自引:0,他引:2
Gary Yohe Kenneth Strzepek 《Mitigation and Adaptation Strategies for Global Change》2007,12(5):727-739
This paper uses the likelihood of flooding along Brahmaputra and Ganges Rivers in India to explore the hypothesis that adaptation
and mitigation can be viewed as complements rather than sustitutes. For futures where climate change will produce smooth,
monotonic and manageable effects, adopting a mitigation strategy is shown to increase the ability of adaptation to reduce
the likelihood of crossing critical threshold of tolerable climate. For futures where climate change will produce variable
impacts overtime, though, it is possible that mitigation will make adaptation less productive for some time intervals. In
cases of exaggerated climate change, adaptation may fail entirely regardless of how much mitigation is applied. Judging the
degree of complementarity is therefore an empirical question because the relative efficacy of adaptation is site specific
and path dependent. It follows that delibrations over climate policy should rely more on detailed analyses of how the distributions
of possible impacts of climate might change over space and time.

Differences in impacts of climate hazards across exposed units are determined by many factors including the severity of the
hazard itself, the population that is exposed to the hazard and the coping capacity of the exposed units to the hazard. Coping
capacity or adaptive capacity results from a combination of development status (generic capacity) and interventions pertinent
to the hazard (specific capacity). This paper explores the extent to which the generic adaptive capacity may explain the variation
in tropical cyclone impacts. Therefore this paper offers an empirical approach by which adaptive capacity may be measured
and validated against actual outcomes. Results not only validate the role of generic adaptive capacity in explaining variations
in impact but also reveal that general development indicators are not very important as far as predicting outcomes is concerned.
Those indicators of development that can be linked to the impact process are significant in explaining and predicting impact.
This can help identify those aspects of generic adaptive capacity which are important from the perspective of policy action
for enhancing adaptive capacity to a particular climate hazard.

In the coming century, modern bioenergy crops have the potential to play a crucial role in the global energy mix, especially
under policies to reduce carbon dioxide emissions as proposed by many in the international community. Previous studies have
not fully addressed many of the dynamic interactions and effects of a policy-induced expansion of bioenergy crop production,
particularly on crop yields and human food demand. This study combines an updated agriculture and land use (AgLU) model with
a well-developed energy-economic model to provide an analysis of the effects of bioenergy crops on energy, agricultural and
land use systems. The results indicate that carbon dioxide mitigation policies can stimulate a large production of bioenergy
crops, dependent on the level of the policy. This production of bioenergy crops can lead to several impacts on the agriculture
and land use system: decreases in forestland and unmanaged land, decreases in the average yield of food crops, increases in
the prices of food crops, and decreases in the level of human demand of calories.

Scientific evidence gathered over the past five years suggests that northern Canada and the Arctic have undergone, and are
undergoing, formidable environmental changes linked to global climate change. Environmental change in the north is expected
to persist and intensify over the course of the next century. When large-scale environmental changes take place, they inevitably
affect people, especially when the cultures and livelihoods of those people depend on their relationship with the environment.
Managing the local impacts of these changes is a matter of adaptation. This paper discusses some of the policy implications
of adaptation––government interventions aiming to build communities’ and regions’ capacities to adapt to environmental changes.
Three arguments for adaptive capacity building interventions in the north are discussed, and these arguments are augmented
by a comparative review of government reactions to the collapse of the cod fishery in Atlantic Canada. Reactive and proactive
policy approaches are discussed, and it is suggested from the comparison that proactive approaches to intervention are desirable
for building adaptive capacity.

A lower molar of a haramiyoid mammal is described from the Toutunhe Formation of Liuhuanggou near Urumqi in the southern Junggar Basin, Xinjiang, China. It is referred to Eleutherodon sp., otherwise exclusively known from the Upper Bathonian of England. It is the first record of the order Haramiyida from Asia and the first Mesozoic mammal described from the southern Junggar Basin. Apart from the English specimens of Eleutherodon and Staffia from the Upper Jurassic of East Africa, it is the geologically youngest haramiyoid known. It is the first vertebrate taxon from the Toutunhe Formation that is probably not endemic and lends some support to the dating of the Formation as late Middle Jurassic, probably Bathonian.

Internal mitigation projects have recently been proposed as an additional flexibility mechanism, particularly in the context
of the European Union. Their main objective is to engage sectors not included in the European Union emissions trading scheme
(EU ETS) in cost-effective emissions reductions. However, in this paper it is argued that, when assessed in terms of dynamic
efficiency, the instrument is likely to be, at best, irrelevant to induce the scale of systemic technological changes which
are required to tackle the climate change problem and, at worst, detrimental for this task. Insights from the Evolutionary
Economics of technological change complemented with political economy considerations are used to support this claim.

There is substantial uncertainty regarding baseline greenhouse gas (GHG) emissions forecasts—i.e., how GHG emissions will
grow over time in the absence of policy intervention. Thus baseline uncertainty should be a key consideration in setting GHG
emissions targets as a mitigation strategy to respond to global climate change. At a minimum, the emissions target must be
less than the baseline level to induce changing behavior and new investment. Despite this fundamental policy criterion, baseline
considerations have played only a minor role in target setting under international climate policy. Baseline uncertainty applies
to both absolute and intensity based emissions targets. It is demonstrated that one advantage of intensity targets is reduced
uncertainty in the projected baseline, however there will always be some residual uncertainty in model projections. To illustrate
the importance of considering baseline uncertainty in GHG target setting, the Bush Climate Change Initiative is analyzed against
its projected baseline as a case study of a modest intensity target. Based on comparison with historical data, the range of
projections by major energy-economic models, past discrepancies in the accuracy of model projections and the added complexity
of sector-specific drivers for non-CO2 GHGs, it is shown that the Bush Initiative cannot be guaranteed or even expected to deliver actual reductions against an
uncertain baseline. This finding emphasizes the importance of setting a target that accounts for baseline uncertainty to achieve
genuine mitigation of GHG emissions.

Over the past decade “bicellar” lipid mixtures composed of the long-chain dimyristoyl phosphatidylcholine (DMPC) and the short-chain
dihexanoyl PC (DHPC) molecules have emerged as a powerful medium for studying membrane associated, biologically relevant macromolecules
and assemblies. Depending on temperature, lipid concentration and composition these lipid mixtures can assume a variety of
morphologies, some of them alignable in the presence of a magnetic field. This article will examine the biophysical studies
that have elucidated the various morphologies assumed by these lipid mixtures, and their use in the biochemical studies of
biomolecules.

Community-based vulnerability assessment has often assumed that the local is the relevant level of adaptation to climate change.
This paper suggests that not only do a number of levels from the international to the regional influence which adaptations
can take place locally, but the governance network that is made up by actors on different levels may to a large extent be
formed in responses to globalising factors, such as internationalisation of economies and the changing role of the state.
The paper presents a study of adaptation in reindeer (Rangifier tarandus) herding, forestry and fishing communities in northern Norway, Sweden, and Finland, with a focus on assessing stakeholders’
own perceptions of environmental, socio-political and economic factors that affect them. In general, the paper illustrates
the integration of non-subsistence economies into large and complex interactions where local adaptation is a result of the
sum of stresses impacting individual entrepreneurs, and the potential they have to adapt their practices given governance
(and their access to support) on different scales.

Synergisms between climate change mitigation and adaptation: an insurance perspective 总被引:1,自引:0,他引:1
Evan Mills 《Mitigation and Adaptation Strategies for Global Change》2007,12(5):809-842
As the world’s largest industry, the insurance sector is both an aggregator of the impacts of climate change and a market
actor able to play a material role in decreasing the vulnerability of human and natural systems. This article reviews the
implications of climate change for insurers and provides specific examples of insurance-relevant synergisms between adaptation
and mitigation in the buildings and energy sectors, agriculture, forestry, and land use. Although insurance is far from a
“silver bullet” in addressing climate change, it offers significant capacity and ability to understand, manage, and spread
risks associated with weather-related events, more so today in industrialized countries but increasingly so in developing
countries and economies in transition. Certain measures that integrate climate change mitigation and adaptation also bolster
insurers’ solvency and profitability, thereby increasing their appeal. Promising strategies involve innovative products and
systems for delivering insurance and the use of new technologies and practices that both reduce vulnerability to disaster-related
losses and support sustainable development. However, climate change promises to erode the insurability of many risks, and
insurance responses can be more reactive than proactive, resulting in compromised insurance affordability and/or availability.
Public–private partnerships involving insurers and entities such as the international relief community offer considerable
potential, but have not been adequately explored.

We investigate the role of domestic allowance allocation and global emissions constraints for the carbon-market impacts of
linking the EU Emissions Trading Scheme (ETS) internationally. Employing a quantitative simulation model of the global carbon
market, we find that the economic benefits from connecting the European ETS to emerging non-EU schemes strongly depend on
the regional allowance allocation of the linking participants: In a world of moderate carbon constraints, an economically
efficient regional allowance allocation induces a much stronger fall in total compliance costs than a sub-optimal (i.e. too
high) domestic allocation of emissions permits. However, a more efficient (i.e. stricter) allocation shifts abatement efforts
and compliance costs to energy-intensive industries which are covered by the domestic ETS. We further find that committing
to ambitious global emissions reduction targets (compatible with stabilizing CO2 concentrations at 450 ppm) induces much stronger regional abatement efforts and substantially higher compliance costs for
the abating regions. In such an ambitious climate policy regime, an efficient domestic allocation of allowances is even more
important from an economic perspective: Here, linking emissions trading schemes diminishes the associated compliance costs
on the largest scale.

Recent paleogeographic scenarios postulate the isolation of continental Africa during the Late Cretaceous. The absence of abelisaurid theropods from Upper Cretaceous African strata was offered as support of hypothesized African isolation with the acknowledgement that the paucity of African abelisaurids may be mostly an issue of sampling. Here we report on a shed theropod tooth from the Upper Cretaceous (Maastrichtian, ∼70 Ma) Duwi Formation of Egypt. The tooth was referred to the Malagasy abelisaurid “Megalosaurus” crenatissimus (=Majungasaurus crenatissimus) in 1921. A discriminant function analysis was run to test for morphological congruence between the Egyptian tooth and the dentitions of 24 theropod taxa. The analysis correctly classified 96.6% of the teeth in the sample and assigned the tooth to Majungasaurus. As current paleogeographic reconstructions posit Madagascar had attained its current position relative to Africa before the Late Cretaceous, it is unlikely that the Egyptian tooth actually pertains to Majungasaurus. Nevertheless, its classification as an abelisaurid supports its referral to the clade. This tooth thus constitutes defensible evidence of an abelisaurid from the post-Cenomanian Cretaceous of mainland Africa. Combined with recent discoveries of abelisaurids in Niger and Morocco, the result indicates that Abelisauridae was a diverse group in Africa during the Cretaceous, existing in multiple places for at least ∼25 Ma and weakens support for hypotheses of an isolated Africa during the Late Cretaceous.Electronic Supplementary Material Supplementary material is available for this article at
