Our perception of design is changing, for design today is no longer concerned only with aesthetics. Now the key factors are interdisciplinary competence and approaches to problem solving. Both politicians as well as businesses recognise design's hybridity and increasingly implement it as a driver of sustainable development (see Chap. 2: Design as a Key Management Factor for Sustainability).
But what exactly does "sustainability" mean? What does it mean in this specific context? People must make use of natural resources to meet their basic needs. In this process, resources are transferred into commercial circulation and usually transformed into products with a particular function. Yet the environment is limited and humanity uses more resources than the Earth can sustainably provide. It is time to rethink and generate the same usage while consuming fewer resources (see Chap. 3: Environmental Space - Challenging Transitions).
Most countries have incorporated sustainability strategies into their political agendas in order to counteract the threats of climate change caused by the overuse of natural resources, high CO2 emissions, and other factors. The indicators for these strategies vary greatly from country to country (see Chap. 4: Sustainability - Challenges, Politics, Indicators).
These indicators need to be taken into account if we are to successfully implement a product or service within a specific context. A concept can only be successful when country-specific indicators are taken into account and the societal context is incorporated into the plan right from the start. The goal is to develop services that support national sustainability targets in production and consumption systems (see Chap. 5: Managing Sustainable Development).
When it comes to companies, these changes can simply be introduced in the form of services or products. In the end, it is the users who decide on the success or failure of innovative solutions by either integrating them into their daily lives or ignoring them. Solutions will only be integrated into users' lives when their role within the social framework remains unchallenged by behavioural transformations caused by use of the solution. In order for users to be able to adopt innovations, sustainable development must take place simultaneously on many different levels. These multi-levelled transitions allow for the transformation of society as a whole. Designers can act as agents of change by providing the needed innovations (see Chap. 6: Transition Requires Change Agents for Sustainability).
If we are to develop suitable solutions and new approaches, the real needs have to be analysed at the beginning of the development process. New physical products, which frequently result in auxiliary products, are often developed without taking into account the overall context, whereas the development of service-orientated solutions is ignored. A physical product is not absolutely necessary. A service (which is naturally dependent on physical products) can usually fulfil the need just as well - or perhaps even better and at a lower cost – while using fewer or no resources (see Chap. 7: Needs & Services - An Approach). There are a variety of possible approaches to integrate sustainability into the design process (see Chap. 8: Design Process).
Precisely which solution is "most or more sustainable" (this is dependent on the defined targets and the indicators used) is often not immediately obvious, and we must turn to a set of methods for a transparent and tangible assessment (see Chap. 9: Sustainability Assessment in Design - Overview and Integration of Methods).
This report analyses the international climate negotiations at the UN climate conference in Warsaw in November 2013. The report covers the discussions under the Durban Platform on developing a new comprehensive climate agreement by 2015 and increasing short-term ambition as well as the issues relating to near-term implementation of previous decisions in the areas of emission reductions and transparency, adaptation, loss and damage, finance and technology. The report concludes that Warsaw once again starkly highlighted the sharp divisions and lack of trust among countries. Industrialised countries' collective lack of leadership strongly contributed to re-opening the traditional North-South divide. As a result, on many issues the outcomes hardly go beyond the lowest common denominator. The conference only agreed on the bare minimum to move the 2015 process forward and also made no headway in strengthening short-term ambition. Some progress was made with the establishment of the "Warsaw international mechanism for loss and damage associated with climate change impacts" and the completion of the rules for reducing emissions from deforestation and forest degradation. However, here as well further substance, in particular financial support from industrialised countries, is required to actually fill these mechanisms with meaning. If countries want to escape from groundhog day, they will have to start seeing and utilizing the UN climate process rather differently.
There's no decarbonisation without energy efficiency : but take care of the "rebound effects"
(2013)
Der angestrebte starke Ausbau Erneuerbarer Energien (EE) für die Stromerzeugung wird bisher hauptsächlich mit der Frage verbunden, wie schnell und umfangreich die Stromnetze ausgebaut werden müssen und in welchem Umfang es welcher neuer Energiespeicher bedarf. Die mögliche große Bedeutung, die die bestehenden Gasnetze und -speicher für den EE-Ausbau und ihre Integration via Einspeisung von Wasserstoff oder auch synthetischem Methan aus EE-Strom haben können, findet dagegen nur wenig Berücksichtigung. Es wird zwar z. B. in der dena Netzstudie II für das heutige Erdgasnetz ein sehr großes, noch unerschlossenes Potenzial als "Stromspeicher" in Höhe von umgerechnet 130 Mrd. kWhel ausgewiesen. Gleichwohl wurde das Erdgasnetz nicht in die Berechnungen der dena Netzstudie mit einbezogen. Durch eine synchrone aber räumlich getrennte Kombination von "Stromspeicherung" (Power-to-Gas) und Stromerzeugung (Gas-to-Power) könnten die bestehenden Gasinfrastrukturen prinzipiell aber auch für einen weiträumigen "Stromtransport" genutzt werden. Diese Option wird vor dem Hintergrund des stockenden Stromnetzausbaus auf ihre Machbarkeit und Synergieeffekte mit dem Stromnetzausbau hin untersucht.
Dazu werden im Rahmen dieser Studie folgende Leitfragen bearbeitet:
Wie wird aus heutiger Sicht (Metaanalyse) der Bedarf für den Ausbau des Stromnetzes und an Energiespeichern sowie die Rolle von Power-to-Gas gesehen? Welche technischen Potenziale und Synergieeffekte bietet die bestehende Gasinfrastruktur in Deutschland für eine Entlastung des Stromnetzausbaus? Welche Kosten sind damit heute und in Zukunft verbunden und welche Kosten können dadurch ggf. reduziert werden? Welche Hemmnisse sind zu beachten und wie können sie ggf. überwunden werden?
Based on the European Waste Framework Directive and the German Recycling Management Act of 01.06.2012 the objectives for a national waste prevention programme were defined. As main objective, according to art. 1 WFD, the "prevention or reduction of the disadvantageous impacts of waste generation and management on the human health and the environment" is recommended. Indicators for a quantitative and qualitative monitoring are derived for both, the individual measures as well as for a waste prevention programme.
