Estimating the sufficiency potential in buildings : the space between underdimensioned and oversized
(2019)
The emission reduction potential of energy efficiency and energy supply in buildings is estimated in various energy and climate action plans, scenarios, and potential analyses. But the third pillar of sustainability - sufficiency - is neglected in most studies.The increasing demand of space per person in the residential sector is a trend in most European countries. Its implication on energy use, demand for resources like land, building material, equipment, and waste production is enormous. Next to the ecological impact, the distribution of space has social and societal effects. Thus, sufficiency policies in the building sector complementing efficiency and energy policy are needed for a sustainable development of the European building stock.
But how can a sufficiency potential in the building sector be estimated? How much space and equipment is needed for a decent living and how much is too much? The paper proposes four areas of sufficiency in buildings: space, design and construction, equipment, and use. It presents a set of indicators, a quantitative estimate of energy savings from reduced per capita floor area, and visualises the sufficiency potential in European countries in an experimental approach. The final discussion focuses on the question: What does this mean for policy making?
"400,000 new homes per year are needed in German cities." This figure has been cited repeatedly in political discussions, media, and statements of different groups for a couple of years now. Living space is needed to mitigate the (further) inordinate increase of rents in some cities and regions and to ease finding appropriate flats at affordable prices for low- and medium-income households. But how to activate investors and the real estate market?
Having the triangle of sustainability in mind with its ecologic, social and economic cornerstones the discussion - metaphorically spoken - currently pulls the three corners: Which should have the highest priority?
The economically driven most favourable solution is lowering the requirements for new buildings such as the energy performance to make building cheaper. The social perspective prefers an increase of public social housing investments regardless of efficiency standards. And the ecological side argues that a high performance is needed to reach energy and climate targets in the buildings sector.
Starting at this point of discussion, firstly, the paper reflects the assumptions behind the numbers of new homes needed against a sufficiency background.
Secondly, it presents current changes in German building policies: a new legislation for energy supply and efficiency is currently in preparation.
It discusses the potential to integrate sufficiency aspects in building policies, focussing specifically on the new regulation, financial incentives, and energy advice.
The paper analyses if and to what extent it is likely to balance the three cornerstones of sustainability by integrating sufficiency aspects into efficiency policies. Household experiences with prepayment meters are used as an example to illustrate the potential for tapping efficiency and sufficiency potentials in low-income households considering social, economic, and ecological aspects. Based on the identified (in)consistencies, thirdly, it suggests further development in German policies to make better use of synergies between the ecologic, social and economic demands on buildings.
The Global Stocktake (GST) takes a central role within the architecture of the Paris Agreement, with many hoping that it will become a catalyst for increased mitigation ambition. This paper outlines four governance functions for an ideal GST: pacemaker, ensurer of accountability, driver of ambition and provider of guidance and signal. The GST can set the pace of progress by stimulating and synchronizing policy processes across governance levels. It can ensure accountability of Parties through transparency and public information sharing. Ambition can be enhanced through benchmarks for action and transformative learning. By reiterating and refining the long term visions, it can echo and amplify the guidance and signal provided by the Paris Agreement. The paper further outlines preconditions for the effective performance of these functions. Process-related conditions include: a public appraisal of inputs; a facilitative format that can develop specific recommendations; high-level endorsement to amplify the message and effectively inform national climate policy agendas; and an appropriate schedule, especially with respect to the transparency framework. Underlying information provided by Parties complemented with other (scientific) sources needs to enable benchmark setting for collective climate action, to allow for transparent assessments of the state of emissions and progress of a low-carbon transformation. The information also needs to be politically relevant and concrete enough to trigger enhancement of ambition. We conclude that meeting these conditions would enable an ideal GST and maximize its catalytic effect.
Additionality revisited : guarding the integrity of market mechanisms under the Paris agreement
(2019)
The Paris Agreement requires mitigation contributions from all Parties. Therefore, the determination of additionality of activities under the market mechanisms of its Article 6 will need to be revisited. This paper provides recommendations on how to operationalize additionality under Article 6. We first review generic definitions of additionality and current approaches for testing of additionality before discussing under which conditions additionality testing of specific activities or policies is still necessary under the new context of the Paris Agreement, that is, in order to prevent increases of global emissions. We argue that the possibility of "hot air" generation under nationally-determined contributions (NDCs) requires an independent check of the NDC's ambition. If the NDC of the transferring country does contain "hot air", or if the transferred emission reductions are not covered by the NDC, a dedicated additionality test should be required. While additionality tests of projects and programmes could continue to be done through investment analysis, for policy instruments new approaches are required. They should be differentiated according to type of policy instrument. For regulation, we suggest calculating the resulting pay-back period for technology users. If the regulation generates investments exceeding a payback period threshold, it could be deemed additional. Similarly, carbon pricing policies that generate a carbon price exceeding a threshold could qualify; for trading schemes an absence of over-allocation needs to be shown. The threshold should be differentiated according to country categories and rise over time.
How can existing national climate policy instruments contribute to ETS development? : Final report
(2019)
Before introducing an emissions trading system, jurisdictions have to consider the ex-isting energy and climate policy framework. This report seeks to analyse and evaluate non-ETS climate policy instruments, such as carbon taxes or green certificate trading schemes, regarding their suitability to serve as a basis for establishing emission trading systems. There is a general assessment of prototypical policy instruments. Besides, the report contains insights from case studies in India and Mexico. The report is meant to inform ETS development by showing how existing policy instruments could contribute to this process and by illustrating how non-ETS policy instruments could coexist with an emissions trading system, allowing for an effective policy mix.
Global climate
(2019)
The twenty-third Conference of the Parties (COP-23) of the United Nations Framework Convention on Climate Change (UNFCCC) was held in Bonn on 6-17 November 2017, under the presidency of Fiji. COP-23 focused, in particular, on developing rules to implement the 2015 Paris Agreement and on raising ambition for climate protection. Since this was the first "Oceanic" COP, special attention was given to supporting the countries of the Global South in their efforts to reduce emissions, adapt to climate change, and deal with the unavoidable impacts of climate change. This article summarizes the main developments and results of COP-23.
The transformation of cities towards sustainable and inclusive development is a key objective of the New Urban Agenda (United Nations 2017). Transport infrastructure is a critical factor in shaping cities, determining the energy intensity of mobility and providing access to essential social and economic opportunities. The sector also plays an important role in global climate change mitigation strategies, as it currently accounts for about 23% of global energy-related greenhouse gas emissions (IPCC 2014).
There is substantial potential to improve urban access, air quality, safety and the quality of life in cities along with reducing Greenhouse Gas Emissions if an integrated policy approach is applied that combines all intervention areas for transport policy and involves all levels of government. A package that achieves low-carbon transport and fosters sustainable developed includes avoided journeys through compact urban design and shifts to more efficient modes of transport, uptake of improved vehicle and engine performance technologies, low-carbon fuels, investments in related infrastructure, and changes in the built environment. From a governance perspective, all relevant political institutions at the local and national level need to be involved in the coalition building along with key societal actors, such as unions, industry and civil society organisations. Bringing the policy objectives of these actors together with an integrated policy package is a vital step towards a low-carbon, sustainable mobility system.
Policy design and governance are critically interlinked as the ability of institutions to find a political consensus and to maintain policy stability heavily influences the success of measures to shape the transformation pathway towards sustainable mobility. This thesis aims to analyse these linkages and highlight the role of different policy and governance approaches. This analysis builds on transport and urban development research, but takes a transdisciplinary research perspective, building on the Multi-Level-Perspective on sustainability transitions (Geels 2002) and aims to highlight the potential for a consensus oriented policy approach (Lijphard 1999) that builds on co-benefits among key policy objectives and coalitions among key political actors, which leads to the main question for this thesis and the focus areas for the analysis.
Last year's conference of the global climate change regime took place from 2 until 15 December 2018 in Katowice, Poland. The conference had two main objectives: operationalising the Paris Agreement by adopting detailed rules for its implementation, and starting the process of strengthening Parties' climate protection contributions. This article covers the negotiations on these two sets of issues and also includes a discussion of other recent climate activities by Parties and non-Party actors. Success of the negotiations in Katowice was far from assured, but in the end COP24 concluded with the adoption of the "Katowice Climate Package" setting out detailed guidelines on how to implement its various elements. However, the conference fell short on the first objective, none of the major emitting countries was ready to step up its climate ambition. The most important aspect of the Katowice outcome is therefore that it has brought the wrangling about implementation procedures to a close, making way for the true task at hand: the strengthening of national and international activities to protect the climate and the implementation of the existing pledges. Arguably, a key factor that has been slowing down climate policy is the power of entrenched interests. The article therefore concludes with a reflection on how such barriers to climate action may be overcome and what role future COPs may play in this regard.
