CO2 emission estimation in the urban environment: measurement of the CO2 storage term

Eddy covariance has been used in urban areas to evaluate the net exchange of CO2 between the surface and the atmosphere. Typically, only the vertical flux is measured at a height 2–3 times that of the local roughness elements; however, under conditions of relatively low instability, CO2 may accumulate in the airspace below the measurement height. This can result in inaccurate emissions estimates if the accumulated CO2 drains away or is flushed upwards during thermal expansion of the boundary layer. Some studies apply a single height storage correction; however, this requires the assumption that the response of the CO2 concentration profile to forcing is constant with height. Here a full seasonal cycle (7th June 2012 to 3rd June 2013) of single height CO2 storage data calculated from concentrations measured at 10 Hz by open path gas analyser are compared to a data set calculated from a concurrent switched vertical profile measured (2 Hz, closed path gas analyser) at 10 heights within and above a street canyon in central London. The assumption required for the former storage determination is shown to be invalid. For approximately regular street canyons at least one other measurement is required. Continuous measurements at fewer locations are shown to be preferable to a spatially dense, switched profile, as temporal interpolation is ineffective. The majority of the spectral energy of the CO2 storage time series was found to be between 0.001 and 0.2 Hz (500 and 5 s respectively); however, sampling frequencies of 2 Hz and below still result in significantly lower CO2 storage values. An empirical method of correcting CO2 storage values from under-sampled time series is proposed.

Employing the Components of the Human Development Index to Drive Resources to Educational Policies

A new form of composition of the indicators employed to generate the United Nations Human Development Index (HDI) is presented here. This form of composition is based on the assumption that random errors affect the measurement of each indicator. This assumption allows for replacing the vector of evaluations according to each indicator by vectors of probabilities of being the best or the worst according to such attribute. The probabilistic composition of such probabilities of preference according to each indicator into probabilities of being the best or the worst according to all of them generates indices that may unveil, on one hand, performances to be followed and, on the other hand, extreme conditions that an additive composition would hide. Differences between the results of application of the diverse forms of composition are examined in the case of the HDI and in the case of the districts version of the HDI employed to compare Brazilian municipalities. It is verified that the smallest correlation between the education.

Sustainability indexes: why join in? A study of the Corporate Sustainability Index (ISE) in Brazil

In the past decade, indicators have been created to assess the sustainability performance of companies listed in stock exchange markets. Academics and practitioners expect companies to benefit from being listed in such indexes, but evidence of value creation is still scarce. Since virtually all studies about the Corporate Sustainability Index (ISE) of the S~ ao Paulo Stock Exchange (Brazil) e the object of the present study e focused on the value of shares, we initially looked for answers in the finance theory. We collected secondary data about the financial and economic performance of companies forming the ISE's ‘theoretical portfolio’, as these kinds of indexes are also known. In a second stage, we sought additional motivations for companies to make efforts to be listed in the index. We collected additional data and interviewed representatives of key companies listed in the ISE, as well as industry leaders who chose not to participate in the selection process. The results support the main propositions of the institutional theory, as well as the ‘pays to be green’ literature e that the intangible value created by voluntary environmental initiatives, such as access to knowledge, new capabilities and reputational gain, better explain the efforts companies make to be listed in the ISE index

Report of the seminar on the results of the social vulnerability index

The Economic Commission for Latin America and the Caribbean (ECLAC); Subregional Headquarters for the Caribbean and secretariat of the Caribbean Development and Cooperation Committee (CDCC); has been involved for the past three years in the execution of a project NET/00/035: Development of the Social Statistical Databases and a methodological approach for a Social Vulnerability Index (SVI); funded by the Government of the Kingdom of the Netherlands. The project had been conceptualized to produce two outputs, one a social statistical database, and the other, the development of a methodological approach for an SVI. The project was in response to the articulated needs of governments in the subregion, specifically, and the wider international body of policy makers, in general, for greater availability and a better quality of social statistical data and indicators to measure the vulnerability of small States.

Preliminary report on the implementation of the ECLAC work programme subregional activities for the Caribbean. 2008-2009 biennium (Covering the period 1 Janurary 2008- 31 August 2009)

Eighteen months into the implementation of the 2008-2009 biennial strategic work programme, the Economic Commission for Latin America and the Caribbean (ECLAC) Subregional Headquarters for the Caribbean continues to focus on strengthening the delivery of activities through regular internal meetings with programme and research staff and consultations with member countries and other partner institutions. The scaling up of efforts advocating for more evidence-based development policy-making is being advanced utilizing the resources provided through the implementation of an additional seven extrabudgetary-funded projects. This effort is being undertaken in collaboration and in consultation with our major international and regional development partners – United Nations Development Programme (UNDP), United Nations Development Fund for Women (UNIFEM), United Nations Population Fund (UNFPA), United Nations Children’s Fund (UNICEF), Caribbean Community (CARICOM), Caribbean Development Bank (CDB), Organisation of Eastern Caribbean States (OECS), Association of Caribbean States (ACS), Inter-American Development Bank (IDB), World Bank, Department for International Development (DFID), Caribbean Community Climate Change Centre (CCCCC). and others.
