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.

Die Digitalisierung ist längst gelebte Praxis. Jeden Tag werden Milliarden an "digitalen" Handlungen ausgeführt. Beispielsweise werden täglich 207 Mrd. E-Mails verschickt, 8,8 Mrd. YouTube-Videos angesehen und 36 Mio. Amazonkäufe getätigt. Dabei nimmt die Geschwindigkeit, mit der neue Anwendungen entwickelt und etabliert werden, kontinuierlich zu. Es stellt sich also die Frage, was im Energiesektor zu erwarten ist und wie die Entwicklung zielgerichtet genutzt werden kann.
The cement industry is one of the major energy consuming and CO2 emitting sectors in China. In 2010, 1,868 million tons of cement has been produced, which accounted for 56.1% of the world's total cement production. The 11th Five-Year Plan (FYP) (2006-2010) included policy measures for CO2 emission abatement in cement production. Based on the main governmental framework of CO2 mitigation policies at national level in the cement sector, key policies and technologies used during this period are identified and their effects on CO2 reduction are assessed. This paper calculates the reduction of CO2 emissions related to four main policies and technologies for efficient cement production in the 11th and the 12th FYP (2011-2015) with 2005 as a reference year. These are waste heat recovery, closing outdated facilities, substitution for clinker production and other technologies aiming to increase energy efficiency. Due to these measures, we estimate that a total CO2 emission reduction during the 11th FYP of 397 million tonnes could be saved, which is considerably different to 185.75 million tonnes estimated by Zeng (2008) and 303 million tonnes by the NDRC by using different calculation methods. Of the four technologies, the 4th group of energy efficiency increasing techniques was the most important policy and avoided the largest amount of CO2 emissions. Previous energy intensity reduction was mainly due to the outdated production closing and energy efficiency improving. Based on the assessment of technology performance, it appears that there is still a large emission reduction potential in cement production processes. The paper calculates this potential for the 12th FYP period (2011-2015) based on these four identified policy measures. The result is compared to the Chinese government targets in the 12th FYP and promising future CO2 mitigation policies and technologies are proposed, such as the use of alternative energy.
In dem Forschungsprojekt "Technologien für die Energiewende" (TF_Energiewende) bewertet ein Konsortium von drei Verbundpartnern und zehn Technologiepartnern unter der Federführung des Wuppertal Instituts seit Herbst 2016 den mittelfristigen Forschungs- und Entwicklungsbedarf für die zentralen Technologien, die im Rahmen der Energiewende derzeit und zukünftig benötigt werden.
