Der Tourismus spielt eine nicht zu unterschätzende Rolle für den Klimawandel. Denn je weiter das Urlaubsziel, desto größer ist der Energieverbrauch auf dem Reiseweg und die damit verbundenen klimarelevanten Umweltauswirkungen.

Unternehmen verpflichtet sich, Treibhausgasemissionen bis zum Jahr 2015 um 15 Prozent zu senken Weltweite Klimaveränderungen lassen keinen Zweifel daran, dass der Ausstoß an Treibhausgasen erheblich gesenkt werden muss. Dieser Verantwortung wollen sich zunehmend auch Unternehmen stellen. Das Öko-Institut bietet dabei fachliche Unterstützung für die Praxis. Aktuell haben die WissenschaftlerInnen für das Handelsunternehmen Metro Group eine Klimabilanz erstellt und geprüft, wie der Konzern seine Treibhausgasemissionen wirkungsvoll verringern kann. Das Ergebnis: Im Untersuchungsjahr 2006 hat das Unternehmen 4,15 Millionen Tonnen CO2 emittiert. Jetzt hat sich die Metro Group verpflichtet, ihre Emissionen bis zum Jahr 2015 um 15 Prozent zu senken. Das soll vor allem mit Energieeinsparungen erreicht werden.

Published in: Historical Social Research 49 (2024) 1 Nuclear energy has long attracted the attention of scholars in the humanities and social sciences. With this HSR Special Issue, we would like to push the scholarly frontier by highlighting the geographies of nuclear energy in the past and present. Nuclear energy is inherently interwoven with geography. We argue that to fully appreciate and grasp nuclear energy’s geographical and spatial dimensions, approaches from a range of disciplinary and interdisciplinary fields are needed. This special issue thus includes contributions from history, geography, political science, technology assessment, science and technology stud-ies (STS), and other fields. This article introduces this topic by outlining the state of the art of the geographies of nuclear energy and discusses different conceptual frameworks of how to understand nuclear-space interactions. In addition, the individual articles in this issue are briefly presented here and discussed within the research con

The impact of a global phase-out of nuclear energy is assessed for the costs of meeting international climate policy targets for 2020. The analysis is based on simulations with the Prospective Outlook on Long-term Energy Systems (POLES) global energy systems model. The phase-out of nuclear power increases GHG emissions by 2% globally and 7% for Annex I countries. The price of certificates increases by 24% and total compliance costs of Annex I countries rise by 28%. Compliance costs increase most for Japan (+58%) and the US (+28%). China, India, and Russia benefit from a global nuclear phase-out because revenues from higher trading volumes of certificates outweigh the costs of losing nuclear power as a mitigation option. Even for countries that face a relatively large increase in compliance costs, such as Japan, the nuclear phase-out implies a relatively small overall economic burden. When trading of certificates is available only to countries that committed to a second Kyoto period, the nuclear phase-out results in a larger increase in the compliance costs for the group of Annex I countries (but not for the EU and Australia). Results from sensitivity analyses suggest that the findings are fairly robust to alternative burden-sharing schemes and emission target levels.Policy relevanceNew calculations show that the impact of a global phase-out of nuclear energy on global mitigation costs is quite modest, but that there are substantial differences for countries. Total compliance costs increase the most for Japan and the US, but these are rather marginal if measured in terms of GDP. China, India, and Russia benefit from a nuclear phase-out because their additional revenues from selling certificates outweigh the additional costs of losing nuclear power as a mitigation option. The findings also highlight the importance of certificate trading to achieving climate targets in a cost-efficient way. If Japan or the US were to be banned from certificate trading, along with other countries, because of their non-participation in a second Kyoto period, then their compliance costs would increase substantially under a nuclear phase-out. The EU, however, would benefit because certificate prices would be lower. Published in: „Climate Policy“, 14:3, 327-352, DOI: 10.1080/14693062.2014.852018

The agriculture, forestry and other land use (AFOLU) sectors contribute substantially to the net global anthropogenic greenhouse gas (GHG) emissions. To reduce these emissions under the Paris Agreement, effective mitigation actions are needed that require engagement of multiple stakeholders. Emission reduction also requires that accurate, consistent and comparable datasets are available for transparent reference and progress monitoring. Availability of free and open datasets and portals (referred to as independent data) increases, offering opportunities for improving and reconciling estimates of GHG emissions and mitigation options. Through an online survey, we investigated stakeholders’ data needs for estimating forest area and change, forest biomass and emission factors, and AFOLU GHG emissions. The survey was completed by 359 respondents from governmental, intergovernmental and non-governmental organizations, research institutes and universities, and public and private companies. These can be grouped into data users and data providers. Our results show that current open and freely available datasets and portals are only able to fulfil stakeholder needs to a certain degree. Users require a) detailed documentation regarding the scope and usability of the data, b) comparability between alternative data sources, c) uncertainty estimates for evaluating mitigation options, d) more region-specific and detailed data with higher accuracy for sub-national application, e) regular updates and continuity for establishing consistent time series. These requirements are found to be key elements for increasing overall transparency of data sources, definitions, methodologies and assumptions, which is required under the Paris Agreement. Raising awareness and improving data availability through centralized platforms are important for increasing engagement of data users. In countries with low capacities, independent data can support countries’ mitigation planning and implementation, and related GHG reporting. However, there is a strong need for further guidance and capacity development (i.e. ‘readiness support’) on how to make proper use of independent datasets. Continued investments will be needed to sustain programmes and keep improving datasets to serve the objectives of the many stakeholders involved in climate change mitigation and should focus on increased accessibility and transparency of data to encourage stakeholder involvement.
