ABSTRACTBackground: Lisbon has about 500,000 inhabitants and it’s the capital and the main economic hub of Portugal. Studies have demonstrated that exposure to Particulate Matter with an aerodynamic diameter<2.5 μm (PM2.5) have strong association with health effects. Researchers continue to identify new harmful air pollutants effects in our health even in low levels. Objectives: This study evaluates air pollution scenarios considering a Health Impact Assessment approach in Lisbon, Portugal. Methods: We have studied abatement scenarios of PM2.5concentrations and the health effects in the period from 2015 to 2017 using the APHEKOM tool and the associated health costs were assessed by Value of Life Year. Results: The mean concentration of PM2.5in Lisbon was 23 μg/m3 ± 10 μg/m3(±Standard Deviation). If we consider that World Health Organization (WHO) standards of PM2.5(10 μg/m3) were reached, Lisbon would avoid more than 423 premature deaths (equivalent to 9,172 life years’ gain) and save more than US$45 million annually. If Lisbon city could even diminish the mean of PM2.5by 5 μg/m3, nearly 165 deaths would be avoided, resulting in a gain of US$17 million annually. Conclusion: According to our findings, if considered the worst pollution scenario, levels of PM2.5 could improve the life’s quality and save a significant amount of economic resources.Implications:The manuscript addresses the health effects and costs of air pollution and constitutes an important target for improving public policies on air pollutants in Portugal. Although Portugal has low levels of air pollution, there are significant health and economic effects that, for the most part, are underreported. The health impact assessment approach associated with costs had not yet been addressed in Portugal, which makes this study more relevant in the analysis of policies aimed to drive stricter control on pollutants’ emissions. Health costs are a fundamental element to support decision-making process and to orientate the trade-offs in investments for improving public policies so that to diminish health effects, which can impact the management of the local health services and the population’s quality of life, especially after the pandemic period when resources are scarce.

Nas últimas décadas, o tema sustentabilidade tem sido profundamente discutido por meio das conferências e estabelecimento de protocolos internacionais, o que obrigou o mundo corporativo a adaptar‐se aos novos anseios da sociedade e do Estado que buscavam o equilíbrio das esferas social, ambiental e econômica. No mercado de capitais o impacto foi refletido por meio do surgimento de carteiras teóricas compostas por empresas consideradas benchmarkna gestão corporativa sustentável. Este estudo tem como propósito avaliar o desempenho de empresas que compõem o Índice de Sustentabilidade Empresarial da BM&FBovespa (ISE), em contraponto com empresas de mesmo segmento econômico ausentes do índice, no intuito de observar se práticas de sustentabilidade colaboram na valorização das ações das empresas. Foram analisadas oito empresas pertencentes a quatro segmentos diferentes, de 2006 a 2014. Consideraram‐se os aspectos quantitativos, como volatilidade dos preços das ações e valorização. Os resultados demonstraram que, sob o ponto de vista estritamente quantitativo, as empresas que compõem o ISE do segmento de bancos e petroquímicos apresentaram bom desempenho, enquanto as empresas do segmento de energia elétrica e de papel e celulose apresentaram desempenho insatisfatório. Dessa forma, não foi possível determinar uma correlação específica entre o ISE e a valorização das ações ou sua volatilidade.

Due to their toxicity, diesel emissions have been submitted to progressively more restrictive regulations in developed countries. However, in Brazil, the implementation of the Cleaner Diesel Technologies policy (Euro IV standards for vehicles produced in 2009 and low-sulfur diesel with 50 ppm of sulfur) was postponed until 2012 without a comprehensive analysis of the effect of this delay on public health parameters. We aimed to evaluate the impact of the delay in implementing the Cleaner Diesel Technologies policy on health indicators and monetary health costs in Brazil.
