On the pathway to climate neutrality, EU member states are obliged to submit national energy and climate plans (NECPs) with planned policies and measures for decarbonization until 2030 and long-term strategies (LTSs) for further decarbonization until 2050. We analysed the 27 NECPs and 15 LTSs submitted by October 2020 using an interrater method. This paper focuses on energy sufficiency policies and measures in the transport sector.
We found a total of 236 sufficiency policy measures with more than half of them (53 %) in the transport/mobility sector. Additionally, we found 41 measures that address two or more sectors (cross-sectoral measures). From the explicit sufficiency measures within the transport sector, 82 % aim at modal shift. A reduction of transport volumes is much less addressed. Countries plan to use mainly fiscal and economic instruments. Those are in many cases investments in infrastructure of low-carbon transport modes and taxation instruments. Plans on decarbonisation measures are also frequently mentioned. The majority of cross-sectoral measures are carbon taxes or tax reforms, also economic instruments.
On the one hand it is encouraging that Member States strongly emphasize the transport sector in their NECPs and LTSs - at least quantitatively and concerning sufficiency measures - because this sector has been the worst-performing in climate mitigation so far. On the other hand, the measures described seem not sufficient to reach ambitious climate targets, and we doubt that the presented set of policy instruments will get the transport sector on track to mitigate greenhouse gas emissions in the necessary extent.

The German climate change programme (2000) identified the residential sector as one of the main sectors in which to achieve additional GHG reductions. Our case study compiles results of existing evaluations of the key policies and measures that were planned and introduced and carries out some own estimates of achievements. We show, which emission reductions and which instruments where planned and what was delivered until 2004.
Legal instruments such as the revised building code were introduced later than planned and their effects will - at least partly - fall behind expectations. Other legal instruments such as minimum energy performance standards for domestic appliances etc. were - in spite of the programme - not implemented yet.
On the other hand, substantial financial incentives were introduced. Especially schemes granting low-interest loans for building renovation were introduced. However tax subsidies for low-energy buildings were phased out.
In general we can conclude from our case study that Germany was not able to compensate for the slower or restricted implementation of legal instruments through the introduction of financial incentives. Particularly the efficient use of electricity has been left aside as almost no further policy action was taken since 2001.
Thus energy efficiency in the residential sector will not deliver the GHG reductions planned for in the German climate change programme until 2005. From our findings we draw conclusions and recommendations towards policy makers: Which lessons are to be learnt and what has to be done in order to fully harness EE potentials in residential sector as planned for 2010?
"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.
Bad Hersfeld is a small city with about 30.000 inhabitants situated in the middle of Germany. Climate Protection has been on the political agenda in Bad Hersfeld since quite a while. In 1997 the Wuppertal Institute elaborated a first energy and CO2 balance for the city, which was updated in 2007. With the compilation of the CO2 balance it was shown that the emissions in Bad Hersfeld almost stayed at a constant level between 1997 and 2006.
The result was sobering for the local authority. Although some single measures had been implemented, there was no improvement of the CO2-balance.
It was concluded that a successful climate protection strategy needs a comprehensive concept comprising all sectors and a periodic monitoring. Bad Hersfeld commissioned the Wuppertal Institute to develop feasible measures to reduce the CO2 emissions drastically and instruments to overcome existing barriers. In a close cooperation with the City Council and the local municipal utility a climate protection concept was compiled that is rather ambitious for a city of this size.
In consideration of the regional peculiarities12 concrete measures and 7 accompanying measures build the core of the concept with a main focus on energy efficiency (final energy), combined heat and power (CHP) and renewable energies. Another important part of the concept is a municipal support programme to develop the endogenous efficiency potentials and renewable energies in the region. Further to these planning instruments, information and networking activities are compiled as well as a variety of suggestions for a climate protection marketing (Wagner 2008).
Some of these measures that were developed in an iterative and cooperative process between the responsible actors in Bad Hersfeld and the Wuppertal Institute are transferable to other cities and towns. The impeding factors in Bad Hersfeld like the user-investor dilemma, the low capital of small housing associations or the large stock of listed historical buildings, are typical for cities of this size.
After a wave of privatizations in the end of the 1990s, the electrical power supply of many municipalities in Germany has been returned into public hands. Many municipalities discover chances and possibilities for local action, which arise with remunicipalisation. The local policy-makers realize that remunicipalisation offers the opportunity of implementing an independent energy policy at local level which is critical in creating a transformation to a sustainable energy system based on energy efficiency and renewable energies. The municipal ownership allows a strong governance towards more political influence in the local energy market. In addition, there is a clear opinion of the population: 81 % of citizens surveyed say they trust their local municipal utility, compared to only 26 % who say they trust corporations (VKU-Survey, 2010). In summary, there are many good reasons for local politicians to establish their own municipal utilities. The payback for municipalities is tangible when the local utility focuses on reliably providing affordable energy rather than on increasing its returns. The new municipal power utilities stimulate competition and contribute to the renewal / restructuring of the traditional energy market.
The founding of 72 municipal utilities since 2005 leads us to ask for the reasons. The study reviews the German trend towards municipal ownership of local utilities, assessing their performance based on 10 targets related to the energy transition, climate protection, and the local economic impact: 1. Achieving environmental objectives and organization of the local "Energiewende". 2. Higher local added value. 3. Harnessing tax regulations for improving municipal services. 4. Improving the income situation of the city. 5. Democratization of supply and stronger orientation towards the common good (public value). 6. Creating and protecting good jobs. 7. Acting in social responsibility in energy supply. 8. Expansion of eco-efficient energy services. 9. Harnessing customer relations and public image. 10. Materialising synergies with other sectors.
Based on expert opinions, the study finds out that the likelihood of these targets being reached is "high to very high". The aim of this article is to provide a compact and basic understanding of the possible reasons for the phenomenon of remunicipalisation.
