Flood exposure is increasing in coastal cities owing to growing populations and assets, the changing climate, and subsidence. This article provides a quantification of present and future flood losses in the 136 largest coastal cities. Using a new database of urban protection and different assumptions on adaptation, we account for existing and future flood defences. Average global flood losses in 2005 are estimated to be approximately US$ 6 billion per year, increasing to US$ 52 billion by 2050 with projected socio-economic change alone. With climate change and subsidence, present protection will need to be upgraded to avoid unacceptable losses of US$ 1 trillion or more per year. Even if adaptation investments maintain constant flood probability, subsidence and sea-level rise will increase global flood losses to US$ 60–63 billion per year in 2050. To maintain present flood risk, adaptation will need to reduce flood probabilities below present values. In this case, the magnitude of losses when floods do occur would increase, often by more than 50 per cent, making it critical to also prepare for larger disasters than we experience today.
This paper discusses the results of a study of measuring green growth in the Benelux countries (Belgium, The Netherlands and Luxembourg). The study paid particular attention to the challenges of measuring the transition to a low-carbon economy in cross-border areas as they have additional levels of complexity when it comes to measuring and monitoring their low-carbon transition.
In cross- regions, data collection hardly ever coincide with any single data gathering ‘institution’. Moreover, Belgium (Flanders, Brussels, Wallonia), the Netherlands, and Luxembourg have different indicator systems at the national level, and even more so at the more decentralised level which creates problems of data availability, data (in)consistency, and hence comparability.
The book includes case studies from Hannover (Germany), Auckland (New Zealand), Flanders (Belgium), Western Canada, City of Raleigh (United States), and Kyoto (Japan).
Bringing together 35 contributions from over 60 experts from research, the private sector, international organisations and local governments worldwide, ICLEI’s compendium bridges the gap between the global promotion of the concept and its actual realisation on the ground by illustrating the advantages of the Green Urban Economy approach with concrete and practical examples.
By embedding both economic and environmental concerns in policymaking, the compendium calls for smarter approaches and innovation in applying existing tools and new methods towards achieving sustainable urban development. Covering issues such as governance, economics, new business models, green jobs, technology, infrastructure, urban poverty, it is also an acknowledgement of and call for more locally responsive actions, new thinking and research.

In recent years the manufacturing of renewable-energy technologies has become truly global. The associated rise in international investment and trade in goods and services related to renewable energy has been rapid, but it has not always been smooth. Already there have been challenges at the WTO, and the unilateral imposition of countervailing and anti-dumping duties, in response to some countries‘ policies on the grounds that they distort trade. Against this background, this paper surveys, through the lenses of market-pull and technology-push policies, the numerous domestic incentives used by governments to promote renewable energy, focusing on those that might have implications for trade — both those that are likely to increase opportunities for trade and those that may be inhibiting imports or promoting exports. Many OECD countries, and an increasing number of non-OECD countries, have established national targets for renewable energy. To help boost the rate of penetration of renewable energy in their economies, most of the same countries are providing additional incentives.
This report provides estimates of social and financial costs of environmental damage in India from three pollution damage categories: (i) urban air pollution, including particulate matter and lead; (ii) inadequate water supply, poor sanitation, and hygiene; (iii) indoor air pollution; and four natural resource damage categories: (a) agricultural damage from soil salinity, water logging, and soil erosion; (b) rangeland degradation; (c) deforestation; and (d) natural disasters. The estimates are based on a combination of Indian data from secondary sources and on the transfer of unit costs of pollution from a range of national and international studies. The quantification and monetary valuation of environmental damage involves many scientific disciplines including environmental, physical, and biological and health sciences, epidemiology, and environmental economics. Estimates of the costs of degradation are generally reported as a percent of conventional gross domestic product (GDP). This provides a useful estimate of the importance of environmental damages but it should not be interpreted that GDP will increase by a given percent if the degradation were to be reduced to zero.
The paper delves into the agreement to liberalise environmental goods and concludes that because applied tariffs on the defined list of goods are generally low, only a relatively small number of products will actually benefit from a tariff reduction. However, the paper notes that given the political importance of the achievement, the agreement may provide a positive experience to build on in other contexts. The APEC agreement marks the first time a group of major trading partners has managed to agree to a set of environmental products on which they will apply tariff reductions, in stark contrast with the stalled Doha negotiations on environmental goods and services.
