In the future, climate change can impact the effectiveness and costs of water quality improvement measures. This must be taken into account when selecting measures to implement in accordance with the EU Water Framework Directive (WFD). Until now, the consequences of climate change have not been systematically incorporated into the economic analyses called for by the WFD. A new book chapter evaluates the basic approaches used to date, thereby contributing to the necessary discussion on how existing and future programs of measures consider and integrate the consequences of climate change.

Biomethane is a flexible and easily storable fuel that can be used wherever natural gas is used without the need to change any settings on equipment designed to use natural gas. In regions where a natural gas grid already exists, there is a ready-made system for the distribution of biomethane. In chapter 16 of the Biogas Handbook, Ecologic Institute's Dr. Wolfgang Urban briefly introduces the legal framework and technical standards of biomethane feed-in to the German gas network. The chapter furthermore describes the different subsidy schemes and reliefs to encourage biomethane production or utilization; and the different available options for biomethane feed-in and feed-in facilities.

How can energy efficiency contribute to a successful "Energiewende" in Germany? Hans-Joachim Ziesing, Associate at Ecologic Institute, discusses this question in his article "Energy saving and energy efficiency in Germany" in the 2013 issue of the "Yearbook Ecology". He describes the "Energiewende" as a decision stemming from societal and political consensus in Germany. Its implementation, however, remains unclear. In a " Energy Efficiency Key Issues Report", the federal government addresses this issue: besides the promotion of Renewable Energy, more energy efficiency is necessary to successfully implement the "Energiewende".

In this book chapter, Sandra Cavalieri and R. Andreas Kraemer of Ecologic Institute present policy options for the EU and the US for addressing challenges in the changing Arctic, summarizing key findings of the transatlantic Arctic Transform dialogue. The book "Environmental Security in the Arctic Ocean" documents the proceedings of the 2010 NATO Advanced Research Workshop (ARW) in Cambridge, England, that was initiated and co-convened by Ecologic Institute.

In a book chapter (in French), R. Andreas Kraemer of Ecologic Institute and Bernard Barraqué trace the historical development of modern water services in Britain and Germany. The chapter describes the different roles of municipalities and central government in the process.

Geoengineering describes a range of techniques that are proposed to counteract some of the negative impacts of climate change at a global scale, without actually reducing emissions. This chapter provides an overview of geoengineering techniques and the existing international law applicable to them.

In a chapter for the edited volume Metropolitan sustainability: Understanding and improving the urban environment, Max Grünig from the Ecologic Institute discusses non-technical approaches for developing sustainable transport and mobility plans in urban areas. The chapter 'Sustainable urban transport planning' emphasizes that it is important to understand consumer behavior and the characteristics of different urban transport choices in order to find the best solution for different urban areas.

The EU target to raise the share of biofuels in transport to 10 % by 2020 remains one of the most controversial environmental policy decisions in recent years. In this book chapter written by Timo Kaphengst and Katharina Umpfenbach of Ecologic Institute together with Bernd Hirschl and Anna Neumann, the authors examine the role of scientific evidence and impact assessments in the policy process leading up to the adoption of the Renewable Energy Directive.

Handbook chapter on the promotion of the waste management recycling of biowastes under the German Life-Cycle Resource Management Act as amended in 2012 and on the incentives regime for the energy recovery from biowastes particularly in the electricity sector under the German Renewable Energy Sources Act as amended in 2011.

Sustainability aspects are often insufficiently considered, if at all, within standards for evaluations or impact assessments. This book chapter points out the challenges raised by sustainability evaluations and the aspects which should be added to existing evaluation standards.

The growing importance of international law for global climate cooperation is underscored in a new book chapter by Michael Mehling and Arturo Brandt, which recently appeared in the first manual on international environmental law for a Spanish-speaking audience. "Derecho Internacional del Medio Ambiente", a new collection of essays from Cameron May Publishing, covers the foundations of international environmental law, key environmental regimes, and topics of relevance for environmental protection at a global level.

Dr. Wolgang Urban, Fellow at Ecologic Institute, presents guidelines for the further expansion of biogas in the conference proceedings "Biogas in Agriculture - Status and Perspectives." These proceedings contain the specialists' contributions of the second FNR/KTBL Congress "Biogas in Agriculture – Status and Prospects", dealing with current biological, processual, and operational measures to stabilize and improve the investment process. In addition, new conversion methods, the effects of system damages, and legal developments for biogas production are discussed. The proceedings can be purchased at the price of 25 Euro in KTBL online shop.

In a literature review, Ecologic Institute examined the effects of environmental tax reforms on the distribution of wealth among different population groups. The review, which contributed to a study commissioned by the European Environment Agency, was included in a book publication offering in-depth assessments of experiences with environmental tax reforms and the benefits such a reform could bring about when implemented at a larger scale throughout Europe.
