On behalf of the Port of Rotterdam Authority, the Wuppertal Institute developed three possible pathways for a decarbonised port of Rotterdam until 2050. The port area is home to about 80 per cent of the Netherlands' petrochemical industry and significant power plant capacities. Consequently, the port of Rotterdam has the potential of being an international leader for the global energy transition, playing an important role when it comes to reducing CO2 emissions in order to deliver on the EU's long-term climate goals.
The three decarbonisation scenarios all built on the increasing use of renewables (wind and solar power) and the adoption of the best available technologies (efficiency). The analysis focuses on power plants, refineries and the chemical industry, which together are responsible for more than 90 per cent of the port area's current CO2 emissions.
The decarbonisation scenarios describe how CO2 emissions could be reduced by 75 to 98 per cent in 2050 (compared to 2015). Depending on the scenario, different mitigation strategies are relied upon, including electrification, closure of carbon cycles or carbon capture and storage (CCS). The study includes recommendations for local companies, the Port Authority as well as policy makers. In addition, the study includes a reference scenario, which makes it clear that a "business as usual" mentality will fall well short of contributing adequately to the EU's long-term climate goals.
Zielsetzung des Forschungsprojektes war es, Klimaschutzszenarien für Deutschland zu entwickeln, die hinsichtlich ihres klimapolitischen Ziels, d.h. ihres langfristigen Emissionsminderungsbeitrags, im Wesentlichen gleich sind, die aber zum Teil auf unterschiedliche Optionen zur Reduktion der energiebedingten CO2-Emissionen setzen. Diese Klimaschutzszenarien wurden hinsichtlich sozioökonomischer und ökologischer Kriterien evaluiert und miteinander verglichen.
International consensus is growing that a transition towards a low carbon society (LCS) is needed over the next 40 years. The G8, the Major Economies Forum on Energy and Climate, as well as the Ad Hoc Working Group on Long-term Cooperative Action under the United Nations Framework Convention on Climate Change, have concluded that states should prepare their own Low-emission Plans or Low-emission Development Plans and such plans are in development in an increasing number of countries.
An analysis of recent long-term low emission scenarios for Germany shows that all scenarios rely heavily on a massive scale up of energy efficiency improvements based on past trends. However, in spite of the high potential that scenario developers assign to this strategy, huge uncertainty still exists in respect of where the efficiency potentials really lie, how and if they can be achieved and how much their successful implementation depends on more fundamental changes towards a more sustainable society (e.g. behavioural changes).
In order to come to a better understanding of this issue we specifically examine the potential for energy efficiency in relation to particular demand sectors. Our comparative analysis shows that despite general agreement about the high importance of energy efficiency (EE), the perception on where and how to achieve it differ between the analysed scenarios. It also shows that the close nexus between energy efficiency and non-technical behavioural aspects is still little understood. This leads us to the conclusion that in order to support energy policy decisions more research should be done on energy efficiency potential. A better understanding of its potential would help energy efficiency to fulfil its role in the transition towards a LCS.
