The report presents an in-depth analysis of various policies that aim to reduce the greenhouse gas emissions of urban transport. Decarbonising transport lies at the core of efforts to mitigate climate change and has close links to urban sustainability and housing affordability. The report identifies the drivers of rising emissions in the urban transport sector and offers pathways to reduce them through a combination of transport and land use policies. The analysis yields a holistic welfare evaluation of these policies, assessing them according to their environmental effectiveness, their economic efficiency and their impact on fiscal balance and housing affordability. The report concludes that significant reductions in emissions from urban transport can be achieved through a careful alignment of transport policies designed to promote the use of public transit and electric vehicles, and land use policies, which foster a more compact urban form. The study is based on the case of Auckland, New Zealand but the lessons drawn are relevant for institutions and governments working on issues relating to urban sustainability, transport, housing and climate change mitigation.

International regulatory co-operation (IRC) provides an opportunity for countries to consider the impacts of their regulations beyond their borders, to expand the evidence for decision-making, to learn from the experience of their peers and to develop concerted approaches to challenges that transcend borders. This review documents the context of IRC policies and practices in the United Kingdom. It covers both the UK’s unilateral efforts to embed international considerations in domestic rulemaking and its bilateral, regional and multilateral co-operative efforts on regulatory matters. In addition, the review provides a snapshot of IRC in practice in the United Kingdom with four case studies on financial services, nuclear energy, medical and healthcare products and product safety. At a time when IRC is an increasingly essential, yet largely untapped, tool for addressing transboundary policy challenges, this review offers valuable lessons to countries within the OECD and beyond.

This report uses systems thinking tools to address pervasive problems in Slovenia's procurement system that the government has struggled to remedy through traditional regulatory means. The report outlines how room for innovation can be created within highly regulated policy domains and how governments can systematically benefit from it. Systems thinking allows for a new understanding of the role of procurement. The report explores potential reforms that could be designed from the bottom-up, to address specific behavioural and structural barriers – such as public perception, risk aversion, accountability and control functions – that cannot be addressed using only a legalistic approach.

Behavioural insights (BI) has become widely used by public bodies around the world, mostly towards improving the way policies are implemented and influencing individual behaviour. As the field of BI evolves to tackle more complex policy issues, there is widespread perception that BI can and should go beyond the study of individual-level decision processes for higher impact. This report presents research on applying BI to changing the behaviour of organisations, with a focus on fostering elements of a safety culture in the energy sector. It presents comparative findings from experiments with energy regulators in Canada, Ireland, Mexico and Oman, as well as guidance for applying BI to safety culture going forward.

Environmental regulators strive to protect the environment and public health from pollution from economic activity. This report uses the OECD Performance Assessment Framework for Economic Regulators (PAFER) to assess both the internal and external governance of Ireland’s Environmental Protection Agency (EPA). It looks at the EPA’s role and objectives, its financial and human resources, processes for internal management and decision making, and systems for performance assessment. The review acknowledges the EPA’s achievements and good practices, analyses the key drivers of its performance, and identifies a number of challenges and opportunities for improvement to help the regulator prepare for the future.

As 'market referees', regulators contribute to the delivery of essential public utilities. Their organisational culture, behaviour and governance are important factors in how they, and the sectors they oversee, perform. The report uses the OECD Performance Assessment Framework for Economic Regulators to assess both the internal and external governance of Peru's Transport Infrastructure Regulator (OSITRAN). The review discusses OSITRAN's good practices, analyses the key drivers of its performance, and proposes an integrated reform package to help the regulator prepare for the future.
