Overview of Vehicle Exhaust Particle Number Regulations

Vehicle emissions are a significant source of air pollution in cities. Particulate matter (PM) is a pollutant with adverse health effects. Regulations worldwide determine the PM exhaust emissions of vehicles by gravimetric quantification of the mass deposited on a filter over a test cycle. The introduction of particulate filters as vehicle exhaust gas aftertreatment devices led to low PM emissions. A particle number methodology (counting solid particles >23 nm), complementary to the PM mass measurement, was developed by the PMP (Particle Measurement Programme) group of the GRPE (Working Party on Pollution and Energy) of the UNECE (United Nations Economic Commission for Europe) during the first decade of the 21st century. The methodology was then introduced in the EU (European Union) regulations for light-duty (2011), heavy-duty (2013), and non-road mobile machinery (2019). In parallel, during the last 15 years, UN (United Nations) regulations and GTRs (Global Technical Regulations) including this methodology were also developed. To address the on-road emissions, the EU introduced RDE (real-driving emissions) testing with PEMS (portable emissions measurement systems) in 2017. Other countries (e.g., China, India) have also started adopting the number methodology. The PMP group recently improved the current laboratory and on-board methodologies and also extended them to a lower particle size (counting solid particles >10 nm). Due to the rapid evolution of the vehicle exhaust particle number regulations and the lack of a summary in the literature, this paper gives an overview of current and near future regulations. Emphasis is given on the technical specifications and the changes that have taken place over the years.

Digital citizens’ participation right in defense of the environment

The Aarhus Convention of June 25, 1998, of the United Nations Economic Commission for Europe on access to information, public participation in decision-making and access to justice in environmental matters, introduced the commitment of each signing State to ensure, within the framework of its national regulation, that citizens could suit and appeal any decision, or any action or omission that falls within the scope of public participation regarding issues on environmental matters. Hence, citizens are entitled to appeal administratively and judicially against public environmental decisions if they invoke a legal infringement in relation to this issue. Access to justice for violation of the rights of public participation are set out in the same terms on Regulation (EU) number 1367/2006, of September 6, relating to the application, to the institutions and community bodies, of the provisions of the Aarhus Convention on access to information, public participation in decision-making and access to justice on environmental matters. Although the right of access is quite broad, it is not exempt from exceptions, such as those indicated on the Directive 2003/4/EC of the European Parliament and of the Council, of January 28, on public access to environmental information, which has recently been interpreted by the Court of Justice of the European Union on the Judgement (First Chamber) of January 20, 2021 in the Land Baden-Württemberg case (Communications internes). However, all this is not useful if citizens are not granted with the possibility of accessing to control judicially administrative decisions that do not comply with environmental policies with the same extension, because the opportunity for any citizen to be entitled to effectively control these actions is being excluded. This paper aims to analyze the extent of the right of citizens to participate digitally in public decision-making of an environmental nature, and determine if such right is consistent with the possibilities of access to justice in this matter, since only through judicially control of the administrative decisions it is possible to make the participation right effective.

Gender Inequality in Latin America: A Multidimensional Analysis Based on ECLAC Indicators

This article analyzes the behavior of gender indicators on the economic, physical, and decision-making autonomy of Latin-American women, based on data compiled and published in 2020 by the Gender Equality Observatory of the United Nations Economic Commission for Latin America and the Caribbean (ECLAC), for 17 countries. Using the HJ-Biplot multivariate technique, it is concluded that the three evaluated areas interact with each other, in such a way that they cannot be interpreted in isolation because their relationships and interdependencies explain the differences in the participation of men and women in the socioeconomic and political environment of the nations in the region. Additionally, it is concluded that in countries such as Guatemala, Honduras, El Salvador, Bolivia, and Ecuador, greater public policy actions are required to seek the economic empowerment of women; while in Brazil, Mexico, and Colombia, laws are necessary to regulate violence against women. It is necessary to continue promoting gender equality in the region as a determinant factor in methodological frameworks and transformational policies to enable moving towards the construction of sustainable societies and economies.

Specification of Modified Jarvis Model Parameterization for Pinus cembra

The high ambient ozone concentrations cause impairing effects on vegetation leading to plant injuries. The potential ozone uptake to vegetation through open stomata can be quantified using stomatal conductance measurements under the local environmental conditions. This study compares the ozone stomatal conductance to vegetation obtained with a modified Jarvis formula adopted from the Vegetation Manual of United Nations Economic Commission for Europe, and experimental field measurements’ data. The stomatal conductance was measured by a portable photosynthesis and gas exchange analyzer system LiCOR6400. The measurements were performed in the submontane environment of the High Tatra Mountains in Slovakia on Swiss pine (Pinus cembra), as a native species of the local flora. According to previous studies, Swiss pine is considered as an ozone-sensitive species. The modified Jarvis model for the ozone stomatal conductance is compared with the field measurements. The suitable parameterization of the modified Jarvis model for Swiss pine is obtained. The parameterization of stomatal conductance for Swiss pine in the local environment would help understand its specificity and similarity to other conifer species. In the case of using parameterization for a boreal coniferous from the Vegetation Manual of the International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops, validation of the model with the measurements without temperature adjustment of the conifer chamber achieved a coefficient of determination of R2=0.75. This result is not in contradiction with the previous researches. With the optimal set of parameters, obtained in this paper, the Jarvis model reaches R2=0.85. The data suggest that Jarvis-type models with appropriate parameterization are applicable for stomatal conductance estimation for Pinus cembra when the measurements do not modify the temperature regime.

210 Awardee Talk: The Future of Beef: Improved Eating Quality and Livestock Systems, But No Cultured Meat

Beef quality includes intrinsic (e.g., safety, palatability, healthiness) and extrinsic traits (e.g., animal health and welfare, environmental impacts). Concerns for extrinsic traits is increasing. In this context, cultured meat is advertised as a good alternative for consumers who want to be more responsible. However, the control of its safety and of its nutritional composition is still unclear, especially for micronutrients. Regarding environmental issues, the potential advantages of cultured meat related to greenhouse gas emissions are a matter of controversy. In this context, improving existing livestock management to have more eco- and animal-friendly systems is a key issue. In addition, communication to consumers about meat production should be more objective and well-balanced. However, there is still a high level of variability in beef palatability, which induces consumer dissatisfaction. Most grading systems describe carcasses using simple traits (e.g., weight, conformation, fatness). In parallel, research has focused on predicting beef palatability using muscle biochemical traits and biomarkers. For this, a precise definition of variables (e.g. tenderness) and repeatability of the measurements are crucial. Strategic choices have been made for the Meat Standards Australia (MSA) grading scheme to consider real consumers’ expectations, not well estimated by lab approaches. Furthermore, the “big data” approach should be encouraged to improve the Findability, Accessibility, Interoperability, and Reusability of data (the FAIR Principles). The ambitions of the International Meat Research 3G Foundation is to set up an international database with a large number of consumers’ scores to offer a predictive model of beef palatability, flexible enough to consider any local characteristics. This approach is supported by the United Nations Economic Commission for Europe to improve transparency and price signaling along the value chain.

Transboundary Freshwater Ecosystems in International Law

A global water crisis with far-reaching and interconnected environmental, social, health and economic impacts threatens the world. Healthy ecosystems and ecosystem services are degrading, and access to a sustainable water supply is increasingly inequitable both within and between States. This book demonstrates how to overcome the global freshwater ecosystem crisis by matching the scientific recommendations with an international legal framework fit for the task, which re-orientates international water law towards a stronger ecosystem approach that also protects vulnerable societies. It illustrates how to understand the fragmented legally binding and non-binding instruments of the United Nations Economic Commission for Europe environmental treaties as one coherent legal regime, which contributes to strengthening general rules and principles of the law concerning transboundary freshwater ecosystems. With the recent global opening of the UNECE regime, this book explores its potential role within the European region, Central Asia, Caucasus, Africa, the Middle East and beyond.

Part V Subject Matter, Ch.30 Freshwater Resources

This chapter traces the evolution of the legal regime for environmental protection of shared watercourses. Codification of international water law began only in 1970, when the International Law Commission (ILC) started to work on a draft convention on the law of the non-navigational uses of international watercourses. After close to a quarter of a century, five rapporteurs, and fifteen reports, the ILC completed its work and adopted the draft United Nations Convention on the Law of the Non-Navigational Uses of International Watercourses (Watercourses Convention). In parallel, the United Nations Economic Commission for Europe (UNECE) Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Water Convention) was adopted in 1992, and entered into force in 1996. The chapter then analyses and compares the environmental provisions of these two global Conventions. It also considers the influence of the two Conventions on the environmental provisions of subsequent regional and bilateral treaties.

Wicked problems: university research topic convergence despite divergence in local educational and innovation policies

Purpose This study aims to determine how sustainable development (SD) demands (according to the United Nations Economic Commission for Europe’s (UNECE) SD themes from 2005) are connected to the contents of education, research, development and innovation (RDI) in higher education institutions (HEI). Education and the RDI nexus may affect HEI’s capability to handle SD-related wicked problems and enhance their societal impact. Design/methodology/approach This paper examined SD-oriented curricula contents of two universities (Brazil and Finland) and counted the number of SD-related research outcomes. In addition, conceptual modelling was used to analyse the mechanisms that may be directing HEIs’ SD work in local innovation. Findings The data showed a convergence deviation in the RDI of SD-related subjects between the two HEIs. There was no correlation between SD-oriented education and RDI-work in either HEI. Education and RDI processes have different UNECE SD themes at the focal point, and the education-research nexus is lacking. This difference indicates that new SD-related knowledge produced through RDI was not effectively used in education. Modelling revealed that the convergence in RDI outcomes arose from the same kind of local business, industry and societal challenges, implementing effective stakeholder pressures into HEIs. The results may indicate that stakeholder SD needs were not directly transferred into the competence qualification of the curriculum. Originality/value To the best of the authors’ knowledge, this is the first quantitative study to reveal the independence of universities’ SD-related RDI subjects on educational curricula.
