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.

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.

Reducing power consumption is a vital building block for transforming the energy system. In the contribution, we will present insights from an ongoing research project “Power efficiency classes for households” studying how power consumption in households can be sustainably reduced and stabilized over the long term. The approach uses the concept of efficiency classes to provide a comparative feedback on households’ total power consumption. The power efficiency classes of households are developed as an indicator for households to more easily estimate their total power consumption and better implement specific goals for saving power. The efficiency classes range from 1-7 – like the power label of the European Union –, with 1 being the best possible class, i.e. the lowest power consumption. On this basis the power efficiency label pools the total power consumption of a household and assigns it a consumption class. A labelling process for particularly frugal households or households achieving a significant reduction in power use that is harmonized with this procedure makes things simple and transparent and thus increases the motivation to attain a better power efficiency class. An energy audit and corresponding power saving packages help households identify saving potentials in order to improve their power efficiency class. This approach is implemented in 100 selected households in cooperation with power companies and manufacturers of appliances in a field test. The aim of this test is to evaluate the households’ sensitization for their own power consumption and the suitability of the various power saving packages. In the contribution, we will present the power efficiency classes for households and report results from the field test in the participating households. Against this background, we will discuss some implications for implementing and scaling-up sustainable consumption and production (SCP) practices in relation to sustainable energy use, to improve efficiency on a household level and to raise awareness for rebound effects.

To reduce Germany’s total GHG emissions by 95 % by 2050, the building sector must be completely decarbonised. Due to the inertia of the sector, it is necessary to significantly accelerate the renovation of buildings and the transformation towards climate-neutral heat supply technologies. Our analysis identifies which measures need to be implemented by which date at the latest, to achieve the long-term target of full decarbonisation. Based on this we develop a consistent set of policy instruments that would enable the building stock becoming climate neutral in 2050. For both, measures and policies, a roadmap for the heat transition in Germany is developed with short- (2020-2025), medium- (2025-2035) and long-term (2035-2050) guidelines and recommendations. The roadmap of measures is based on an analysis of potential risks and how they could be compensated. Potential risks include for example failing to achieve the refurbishment rates and renovation standards required to realize climate neutrality; or failing to get renewable heat quickly enough into the heating market. Options to offset resulting gaps include an additional use of domestic renewable energy, increased efficiency efforts or the import of renewable energy. The roadmap is divided into four blocks addressing the overall regulatory framework, demand reduction in buildings, heat supply technologies and district heating. The roadmap of measures is “translated” into a roadmap of policy instruments. The policy roadmap includes regulatory approaches, support programs as well as informative instruments. The policy roadmap is designed to provide sufficient incentives for target achievement while avoiding lock-in effects that would undermine meeting the long-term goal.

Environmental aspects are more and more relevant for raw material policy-making and responsible sourcing strategies. This trend is partly based on growing public awareness of problems and impacts associated with extraction and processing of ores and minerals. Disaster events such as the tailing dam failures in Kolontár (Hungary, October 2010) and Bento Rodriguez (Brazil, November 2015) quite frequently highlight the fact that many mining and processing practices are associated with substantial environmental impacts and risks for the local and even regional environments. However, there is also increasing recognition that the rather devastating environmental performance of many past and current mining projects is a major reason for communities around the world to oppose both the development of new and the expansion of existing mines. Although mining companies constantly have to increase their efforts to secure the social license to operate, many scholars already point out that both environmental impacts and associated social and political reactions are emerging as a decisive factor determining current and future raw material supply. In light of these concerns, raw material policy-making requires solid information on environmental hot spots in mining, as well as on raw materials of particular concern. Whereas indicators and information systems are already well developed for geological, technical, structural, political, regulatory, and economic supply risks, there is currently no holistic method and information system for environmental concerns associated with the mining of raw materials. Although life cycle assessment can provide methodological support for various environmental aspects, it has substantial weaknesses in the fields of ecosystem degradation, impacts on fresh- and groundwater resources, and hazard potentials from episodic disaster events. This paper presents a methodology that aims to fill this gap. Our proposed method provides a system of 11 indicators allowing the identification of raw material-specific environmental hot spots and rankings of raw materials. Although the indicator system is qualitative in nature, its composition and aggregation cover the most relevant environmental concerns arising from mining and allow prioritizing of raw materials from a global environmental perspective.

Article 6 of the Paris Agreement creates an international framework for market-based cooperation between countries and/or entities “to allow for higher ambition in their mitigation and adaptation actions and to promote sustainable development“. Article 6.2 provides a framework for engaging in cooperative approaches involving internationally transferred mitigation outcomes (ITMOs). Article 6.4 creates a new United Nations carbon crediting programme, also known as the Paris Agreement Crediting Mechanism (PACM), overseen by the Article 6.4 Supervisory Body. Articles 6.2 and 6.4 are operationalised through decisions taken under the Paris Agreement. While distinct systems, they can intersect, as emission reductions or removals issued as Article 6.4 Emission Reductions (A6.4ERs) under the PACM, or by other eligible carbon crediting programmes can be authorised under Article 6.2 as ITMOs. A6.4ERs that are not authorised as ITMOs are referred to as Mitigation Contribution Units (MCUs).

Frauen sind heute beim Zugang zu klimafreundlichem Wohnen und klimafreundlicher Mobilität benachteiligt. Bei den Kosten für Wärme, Strom und Mobilität sind Frauen finanziell stärker belastet als Männer, besonders wenn sie zur Miete wohnen. Das betrifft insbesondere alleinerziehende Mütter und Rentnerinnen, aber auch Frauen in anderen Lebenssituationen. Gezielte Unterstützungsmaßnahmen für Haushalte mit geringem oder mittlerem Einkommen können demnach Frauen zugutekommen, da sie mehrheitlich solchen Haushalten vorstehen. Diese und weitere Ergebnisse zur geschlechtergerechten Gestaltung der Energie- und Mobilitätswende stellt das Öko-Institut im Rahmen einer Expertise für den Vierten Gleichstellungsbericht der Bundesregierung vor.
