Governments in many countries have sought to accelerate the time taken to make decisions on major infrastructure projects, citing problems of 'delay'. Despite this, rarely has the time variable been given careful empirical or conceptual attention in decision-making generally, or in infrastructure decision-making specifically. This paper addresses this deficit by analysing decision-making on two categories of major infrastructure in the UK – transport and electricity generation – seeking both to generate better evidence of the changes to decision times in recent decades, and to generate insights from treating time as resource and tracking its (re)allocation. We find that reforms introduced since 2008 have done relatively little to alter overall decision times, but that there are marked and revealing changes to the allocation of time between decision-making stages. While public planning processes have their time frames tightly regulated, aspects led by developers (e.g. pre-application discussion) are not; arranging finance can have a bigger effect on project time frames, and central government retains much flexibility to manage the flow of time. Speed-up reforms are also sectorally uneven in their reach. This indicates how arguments for time discipline falter in the face of infrastructure projects that remain profoundly politicised.

This book analyses international Green Infrastructure (GI) planning and design strategies. The GI strategy is widely recognized for its multifunctionality (as a tool for ecological, economic and social enhancement) and multiscalarity. Starting from this assumption, the book intends to implement the concept of GI and blue networks in planning strategies and their linked urban projects. New urban and regional paradigms of the latest years, such as urban sprawl, ecosystem services, biodiversity, urban resilience, climate change and health emergencies, have made it necessary to rethink cities and territories and their related plans and projects. To satisfy these paradigms, worldwide plans and projects have started to focus both on short-term and long-term processes and strategies which integrate environmental, landscape and ecological elements.

Most accessibility measures reported in the literature do not meet certain requirements of transport planners, as the results offered by these indicators are heavily influenced by the geographic location of the places. Peripheral locations invariably figure as being of low accessibility and consequently as possible receptors for new investments, even though they may already have a very good provision of transport infrastructure. In this paper an accessibility indicator is formulated that neutralizes the effect of geographic location. To this end, the customary notion of distance (length, time, or costs) is substituted by another which expresses the ease of access in terms of network efficiency. This indicator can be useful to assist decisions to invest in transport networks, as it is more sensitive than the potential model to the transport infrastructure needs of each individual region. It has been tested by application to the current Spanish Infrastructure Master Plan.

There have been discussions in a range of contexts of the links between spatial planning and actions on major infrastructure. Here this relationship is framed by considering the political, ideological and geographical drivers of state policies and actions in the spatial planning and infrastructure fields. The empirical focus is a study of current large scale spatial planning activities in the UK over the last decade or so, largely within England. Analysis of these cases shows the importance of understanding planning and infrastructure together, given that the emerging initiatives on infrastructure and in big spatial planning are very much connected.

Investment in European electricity transmission requires facilitation at the European level. The rate at which renewable energy is integrated into the power sector over the next decade will necessitate significant transmission infrastructure expansion and upgrades, with clear pan-European objectives. Historically, grid planning was primarily carried out at the national level with limited arrangements to share investment costs and assign benefits with a clear and agreed-upon methodology. Now, however, engagement and cooperation at the regional and European level is increasingly important. The Infrastructure Package, a regulation proposed 19 October 2011 by the European Commission (EC) which brings together national and European infrastructure financing, planning, and development. Because of the importance of electricity infrastructure to Europe's energy and climate objectives, CPI Berlin and the Florence School for Regulation hosted an informal workshop, supported by the Agency for the Cooperation of Energy Regulators (ACER), which brought together perspectives on EU grid infrastructure from regulators, national and EU policy makers, transmission system operators (TSOs), generation companies and academics. This Workshop Report provides a summary of the ideas that emerged from the discussions.
