The maritime part of all transport via the port of Rotterdam is linked to the brunt of all CO2 emissions (87 %) the port can potentially influence. This report aims to quantitatively grasp the maritime transport of the Port of Rotterdam, in terms of ships, total tonnages, energy consumption and CO2 emissions in respect to types of cargo and regions.
In the first and broad part of the report, the emissions and energy demands of sailing ships are assessed. Emissions and energy demand for the port itself are subject of a separate part at the end.
In recent years, many energy scenario studies have proven that a power supply system based on renewable energies (RE) >90 percent is feasible. However, existing scenarios differ significantly in the composition of generation technologies. Some scenarios focus on wind energy in the northern part of Europe, others base on a large utilisation of solar technologies in the south. Apart from the generation capacities, the needed technical flexibilisation strategies such as grid extension, demand flexibilisation and energy storage are generally known and considered in many scenarios. Yet, the impact of different renewable generation strategies on the local utilisation of flexibility options needs to be further assessed. Based upon the BMBF research project RESTORE2050, analyses have been carried out that focus on these interdependencies. The results of the project show that the local utilisation of flexibilisation options depends to a great extent on the technology focus of the long-term renewable expansion strategy. This applies for the spatial flexibilisation as provided by transnational interconnection capacities, especially the ones connecting regions with a surplus of power generation (e.g. GB, Norway and Spain). Another impact of the renewable scenario is seen on the required temporal flexibilisation of electricity generation and demand. In addition, the available options will compete for high utilisation in a future energy system. The differences in the utilisation of these applications, which base on the varying shares of photovoltaic (PV) and wind energy generation, lead to the conclusion that the decision about longterm RE expansion ought to be made very soon in order to avoid inefficient flexibility pathways. Otherwise, if the future RE structure will be kept open, adequate adoption of new flexibility options will be difficult, especially in case of technologies with long lead and realisation time (e.g. new power grids and large scale energy storage devices).
Article 6 of the Paris Agreement establishes three approaches for countries to cooperate with each other in implementing their climate protection contributions. However, Article 6 sketches out only some basic contours; the details are to be filled in by further negotiations. This article surveys the views countries have submitted so far in order to identify the main issues at stake, points of controvery and convergence and possible ways forward. The submissions reveal some sharp differences in opinions on key issues such as the scope of the new mechanisms, how to operationalise the Article 6 requirement to increase ambition, whether to have international provisions on the promotion of sustainable development, and how to protect environmental integrity in the use of Article 6. The article concludes with a number of recommendations on how to address these controversies.
Combating climate change requires a fundamental simultaneous transformation of various sectoral systems that are key to the functioning of our economies and societies, such as energy, industry, transport, housing, and agriculture. This report by the COP21 RIPPLES project examines sector-specific challenges to decarbonisation and what contribution international governance could make to overcoming these challenges.
Taking a sectoral perspective, the report identifies the key governance challenges that exist internationally towards the deep transformations required, and specifies the resulting key governance functions to be fulfilled by means of international cooperation/international institutions.
To this end, the report first clarifies a number of key concepts, including international (climate) governance, international and transnational institutions, institutional complexes and poly-centricity. It then derives a number of functions that international institutions can fulfil from the relevant literature: providing guidance and signals, setting rules, providing transparency and accountability, providing capacity building, technology and finance, and facilitating knowledge and learning. This is the basis for an investigation into the key governance challenges and the potential of international governance in 14 key sectoral systems.

On 7-18 November, the twenty-second Conference of the Parties (COP-22) to the United Nations Framework Convention on Climate Change (UNFCCC) and the twelfth Meeting of the Parties to the Kyoto Protocol (CMP-12) took place in Marrakech. Due to the rapid entry into force of the Paris Agreement, Marrakech also hosted the first Conference of the Parties serving as the Meeting of the Parties to the Paris Agreement (CMA-1). Nobody had expected this one year before in Paris - the entry into force of the Kyoto Protocol, by comparison, had taken eight years. Many hailed the rapid entry into force as further proof of the commitment of the world community to finally tackle the climate problem.
Shaping the Paris mechanisms part III : an update on submissions on article 6 of the Paris Agreement
(2017)
At the 46th meeting of the UNFCCC's subsidiary bodies in Bonn, it was decided that Parties submit their input on selected aspects of the Art. 6 negotiations shortly before COP 23, taking place in Bonn in early November. This Policy Paper summarises the views submitted in October 2017 to identify points of controversy and convergence. It builds on previous papers summarising the views submitted in September 2016 and March 2017, respectively.
Germany's waste management system is one of the world's most advanced - its primary objective is to dispose of waste in a way that is safe for both people and the environ- ment. However, only about 14 per cent of the raw materials used in industry are derived from recycling processes; the remainder are still sourced from primary materials. The circular economy is not yet being implemented on a large enough scale. Recyclates or recycled materials, i.e. secondary raw materials recovered from waste, are being fed back into production and usage processes at volumes that are far below what is possible. If this system were to be improved, loss of value, dependence on volatile commodity markets, lower resource productivity, and externalities in the form of environmental pollution could be avoided. A drive towards digitalisation in industry and the waste management sector could make this happen. A study by the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) indicates that no other lead market in the environmental sector stands to benefit from digitalisation more than the circular economy - and that, at the same time, no sector has ever been so poorly positioned.
This policy brief discusses the importance of SUMPs (Sustainable Urban Mobility Plans). We test the hypothesis that the development of an ambitious plan in itself does not necessarily translate into successful policies and measures and in actual sustainable urban mobility. We find that the existence of a SUMP correlates positively with a higher share of public transport but that the existence of a SUMP does not as yet have a significant impact on the overall share of non-motorised modes of transport.
