Local governments have the power to influence the energy choices of their citizens. Many cities and towns have already encouraged energy efficiency measures. Even so, as demand for energy services continues to grow, the energy infrastructure that every city and town depends on will need to be expanded, upgraded or replaced. This provides the opportunity to increase the deployment of renewable energy technologies and decentralised energy systems, and hence gain the multi-benefits of increased energy security, climate change mitigation and sustainable development, but also the social benefits of reduced air pollution, such as improved health and employment. 

Many combinations of policies have been employed to stimulate local renewable energy development. These policies include: local governance by authority; providing resources; enabling private actors; leading by example; allowing self-governance. Mega-city mayors, down to small-town officials, have successfully introduced such policies, although these vary with location, local resources and population. Cities, Towns and Renewable Energy – “ Yes In My Front Yard “ includes several case studies chosen to illustrate how enhanced deployment of renewable energy projects can result, regardless of a community’s size or location.

The goals of this report are to inspire city stakeholders by showing how renewable energy systems can benefit citizens and businesses, assist national governments to better appreciate the role that local municipalities might play in meeting national and international objectives, and help accelerate the necessary transition to a sustainable energy future.

The negative impacts of climate change will hit poor people and poor countries disproportionately, and further compromise the achievement of their development objectives. Integrating Climate Change Adaptation into Development Co-operation provides essential information and advice on how to facilitate the integration of adaptation into development processes. The objectives of this policy guidance are to: i) promote understanding of the implications of climate change on development practice and the associated need to mainstream climate adaptation in development co-operation agencies and partner  countries; ii) identify appropriate approaches for integrating climate change adaptation into development policies at national, sectoral and project levels and in urban and rural contexts; and iii) identify practical ways for donors to support developing country partners in their efforts to reduce their vulnerability to climate variability and climate change. While efforts to integrate climate change adaptation will be led by developing country partners, international donors have a critical role to play in supporting such efforts.

The Bovine Corneal Opacity and Permeability test method (BCOP) is an in vitro test method that can be used to classify substances as 'ocular corrosives and severe irritants'. The BCOP uses isolated corneas from the eyes of cattle slaughtered for commercial purposes, thus avoiding the use of laboratory animals. Each treatment group (test substance, negative/positive controls) consists of a minimum of three eyes where the cornea has been excised and mounted to a holder. Depending on the physical nature and chemical characteristics of the test substance, different methods can be used for its application since the critical factor is ensuring that the test substance adequately covers the epithelial surface. Toxic effects to the cornea are measured as opacity and permeability, which when combined gives an In Vitro Irritancy Score (IVIS) for each treatment group. A substance that induces an IVIS superior or equal to 55.1 is defined as a corrosive or severe irritant.

The Isolated Chicken Eye  (ICE) test method is an in vitro test method that can be used to classify substances as “ocular corrosives and severe irritants”. The ICE method uses eyes collected from chickens obtained from slaughterhouses where they are killed for human consumption, thus eliminating the need for laboratory animals. The eye is enucleated and mounted in an eye holder with the cornea positioned horizontally. The test substance and negative/positive controls are applied to the cornea. Toxic effects to the cornea are measured by a qualitative assessment of opacity, a qualitative assessment of damage to epithelium based on fluorescein retention, a quantitative measurement of increased thickness (swelling), and a qualitative evaluation of macroscopic morphological damage to the surface. The endpoints are evaluated separately to generate an ICE class for each endpoint, which are then combined to generate an Irritancy Classification for each test substance.

La présente Ligne directrice décrit un essai de dépistage in vivo sur des groupes de poissons (composés de mâles sexuellement matures et de femelles reproductrices) exposés à une substance pendant une durée limitée de leur cycle biologique (21 jours). L’essai à court terme de reproduction a été validé chez le tête-de-boule (Pimephales promelas), qui est donc l’espèce de prédilection. L’essai est mené avec trois niveaux de concentration chimique et les contrôles appropriés, y compris un contrôle contenant le solvent si nécessaire. Pour le tête-de-boule, quatre réplicats sont utilisés pour chaque niveau de concentration et contrôle(s).  Pendant toute la durée de l’essai, la fécondité est en outre évaluée quotidiennement sur le plan quantitatif. A l’issue de cette période d’exposition de 21 jours, deux biomarqueurs sont mesurés chez les mâles et les femelles pour servir d’indicateurs des effets de la substance d’essai sur le système endocrinien ; ces biomarqueurs sont la vitellogénine et les caractères sexuels secondaires. Les gonades sont préservées et l’histopathologie gonadique peut être utilisée pour évaluer l’adaptation du système reproducteur des animaux testés et pour confirmer les éléments de preuve apportés par les autres biomarqueurs.

La méthode d’essai  sur œil de poulet isolé (OPI) est une méthode d’essai in vitro pouvant être utilisée pour classer des substances parmi les substances « corrosives et fortement irritantes pour les yeux ».

La méthode OPI utilise des yeux prélevés sur des poulets provenant d’abattoirs, où ils sont tués à des fins de consommation humaine, évitant ainsi le recours à ders animaux de laboratoire. L’œil est énucléé et placé sur un support d’œil, la cornée étant en position horizontale. La substance d’essai et les contrôles négatifs/positifs sont appliqués sur la cornée.
Les effets toxiques pour la cornée sont estimés à partir d’une évaluation qualitative de son opacité, une évaluation qualitative de l’endommagement de l’épithélium sur la base de la rétention de fluorescéine, une mesure quantitative de l’augmentation de son épaisseur (gonflement), et une évaluation qualitative de l’endommagement morphologique macroscopique de la surface. Chacune de ces évaluations se traduit par un classement OPI, et la combinaison des classements correspondants fournit un classement d’irritation pour chaque substance.

This Test Guideline is designed for assessing the effects of chemicals on the reproduction of collembolans in soil. The parthenogenetic Folsomia candida is the recommended species for use, but an alternative species such as sexually reproducing Folsomia fimetaria could also be used if they meet the validity criteria. This Guideline can be used for testing both water soluble and insoluble substances but it is not applicable to volatile ones. The Guideline aims to determine toxic effects of the test substance on adult mortality and reproductive output expressed as LCx and ECx respectively, or NOEC/LOEC value. The number of treatment concentrations varies depending on endpoints to be determined. For a combined approach to examine both the NOEC/LOEC and ECx, eight concentrations in a geometric series with four replicates for each concentration as well as eight control replicates should be used. In each test vessel, 10 juveniles F. candida (or 10 males and 10 females adults F. fimetaria) should be placed on 30 g of modified OECD artificial soil using a 5 % organic matter content. The duration of a definitive reproduction test is 4 weeks for F. candida or 3 weeks for F. fimetaria.

Cette Ligne directrice décrit un essai in vitro qui fournit des informations mécanistiques et peut être utilisé à des fins de dépistage et de mise en priorité. Le système utilise la lignée cellulaire hERalpha-HeLa-9903 provenant d’une tumeur cervicale humaine, transfectée de façon stable. Cette lignée cellulaire permet de mesurer la capacité d’une substance d’essai à induire la transactivation de l’expression du gène luciférase, médiée par le récepteur d’œstrogène alpha humain hERalpha. Les cellules sont exposées à 7 concentrations non cytotoxiques de la substance d’essai pendant 20-24 heures afin de provoquer la synthèse de produits de gènes rapporteurs. Quatre substances de référence sont incluses dans chaque essai : un estrogène fort (17bêta-estradiol, un faible (17alpha-estradiol), un très faible (17alpha-méthyltestostérone) et un témoin négatif (corticostérone). L’activité de l’enzyme luciférase est mesurée par un luminomètre. Une substance d’essai est considérée comme répondant positivement si la réponse maximale induite est égale ou excède 10 % de la réponse du témoin positif (1 Nm 17bêta-estradiol) dans au moins deux parmi deux, ou deux parmi trois expérimentations.

La méthode d’essai d’opacité et de perméabilité de la cornée bovine pour l’identification de substances corrosives et fortement irritantes pour l’œil (OPCB) est une méthode d’essai in vitro pouvant être utilisée pour classer des substances parmi les substances « corrosives et fortement irritantes pour l’œil ». La méthode OPCB utilise des cornées isolées provenant d’yeux de bovins abattus à des fins commerciales, évitant ainsi l’utilisation d’animaux de laboratoire.
Chaque groupe de traitement (substance d’essai et témoins négatifs et positifs) est composé de trois yeux au minimum, dont la cornée a été prélevée et placée dans la chambre d’un porte-cornée. En fonction des propriétés physico-chimiques de la substance d’essai, différentes méthodes peuvent être utilisées pour l’appliquer, mais il est important que la substance recouvre bien la surface épithéliale. Les effets toxiques pour la cornée sont estimés à partir des mesures de son opacité et de sa perméabilité, qui une fois  combinées, fournissent le score d’irritation in vivo (SIIV) pour chaque groupe de traitement. Une substance qui induit un SIIV≥ 55.1 est classée « corrosive ou fortement irritante ».

This Test Guideline describes an in vivo screening assay for fish reproduction where sexually mature male and spawning female fish are held together and exposed to a chemical during a limited part of their life-cycle (21 days). The short term reproduction assay was validated in the fathead minnow (Pimephales promelas) and this is the recommended species. The assay is run with three test chemical concentrations and the necessary controls, including a carrier control if necessary. For the fathead minnow, four replicate test vessels are used for each treatment level and control(s). During the conduct of the assay, the egg production is measured quantitatively daily in each test vessel. At termination of the 21-day exposure period, two biomarker endpoints are measured in males and females separately, as indicators of endocrine activity of the test chemical; these endpoints are vitellogenin and secondary sexual characteristics. Gonads of both sexes are also preserved and histopathology may be evaluated to assess the reproductive fitness of the test animals and to add to the weight of evidence of other endpoints.

Cette Ligne directrice est destinée à évaluer les effets des substances chimiques sur la reproduction des collemboles dans le sol. Folsomia candida,  qui se reproduit par parthénogénèse, est l’espèce recommandée, mais une autre espèce telle que Folsomia Fimetaria, dont la reproduction est sexuée, peut aussi être utilisée si les critères de validité sont remplis. Cette Ligne directrice peut être utilisée pour des substances solubles ou insolubles, mais elle ne s’applique pas aux substances volatiles. L’objectif est de déterminer les effets toxiques de la substance sur la mortalité des adultes et sur le taux de reproduction exprimé respectivement par la CLx et la CEx, ou par les valeurs CSEO/CMEO. Le nombre de concentrations d’essai varie en fonction des effets à mesurer. Pour une approche combinée visant à déterminer les CSEO/CMEO, huit concentrations formant une série géométrique, quatre réplicats pour chaque concentration et huit réplicats témoins sont utilisés. Dans chaque récipient d’essai, 10 juvéniles F. candida (ou 10 males et 10 femelles F. fimetaria) sont placés sur 30 g de sol artificiel modifié OCDE contenant 5 % de matière organique. La durée d’un essai de reproduction définitif est de 4 semaines pour F. candida et de 3 semaines pour F. fimetaria.

This Test Guideline describes an in vitro assay, which  provides mechanistical information, and can be used for screening and prioritization purposes. The test system utilises the hERalpha-HeLa-9903 cell line derived from a human cervical tumor and stably transfected. This cell line can measure the ability of a test chemical to induce hERalpha-mediated transactivation of luciferase gene expression. The cells are exposed to 7 non-cytotoxic concentrations of the test chemical for 20-24 hours to induce the reporter gene products. Four reference chemicals should be included in each experiment: a strong estrogen (17beta-estradiol), a weak estrogen (17alpha-estradiol), a very weak estrogen (17alpha-methyltestosterone) and a negative control (corticosterone). The activity of the luciferase enzyme is measured in a luminometer. A test chemical is considered to be positive if the maximum response induced is equal to or exceeds 10% of the response of the positive control (1 nM 17alpha-estradiol) in at least two of two or two of three runs.

This method provides information on health hazard likely to arise from short-term exposure to a test article (gas, vapour or aerosol/particulate test article) by inhalation.

The revised Test Guideline describes two studies: a traditional LC50 protocol and a Concentration x Time (C x t) protocol. It can be used to estimate a median lethal concentration (LC50), non-lethal threshold concentration (LC01) and slope, and to identify possible sex susceptibility. This Test Guideline enables a test article quantitative risk assessment and classification according to the Globally Harmonized System for the Classification and Labelling of Chemicals. In the traditional LC50 protocol, animals are exposed to one limit concentration or to three concentrations, at least, for a predetermined duration, generally of 4 hours. Usually 10 animals should be used for each concentration. In the C x T protocol, animals are exposed to one limit concentration or a series of concentrations over multiple time durations. Usually 2 animals per C x t interval are used. Animals (the preferred species is the rat) should be observed for at least 14 days. The study includes measurements (including weighing), daily and detailed observations, as well as gross necropsy.

The Hershberger Bioassay is an in vivo short–term screening test. It evaluates the ability of a chemical to elicit biological activities consistent with androgen agonists, antagonists or 5 á-reductase inhibitors. The current bioassay is based on the changes in weight of five androgen-dependent tissues in the castrate-peripubertal male rat: the ventral prostate, seminal vesicle (plus fluids and coagulating glands), levator ani-bulbocavernosus muscle, paired Cowper’s glands and the glans penis. In order to establish whether a test substance can have androgenic or antiandrogenic action, two – respectively three - dose groups of the test substance, plus positive and vehicle (negative) controls are normally sufficient. The test substance is administered by gavage or subcutaneous injection daily for 10 consecutive days. To test for antiandrogens, the test substance is administered together with a reference androgen agonist. Each treated and control group should include a minimum of 6 animals.  The animals are necropsied approximately 24 hours after the last administration of the test substance. The tissues are excised and their fresh weights determined.  A statistically significant increase (androgenic) or decrease (antiandrogenic) in the weights of two of the five tissues indicates a positive response in this assay.

The method described by this Test Guideline provides information that allows hazard assessment for short-term exposure to a test article by inhalation, and allows the substance to be classified according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The test method is based on a stepwise procedure, each step using 3 animals of each sex (the preferred species is rat). Animals are exposed in  inhalation chambers to a pre-defined concentration for 4 hours. Absence or presence of compound-related mortality of the animals at one step will determine the next step. Animals in severe pain or distress should be humanely killed. The starting concentration is selected from one of four fixed levels corresponding to GHS categories 1-4 for gases, vapours or aerosols. Animals are observed daily for clinical signs of toxicity for a total of at least 14 days. Animals' body weights should be determined at least weekly. All the animals should be subjected to gross necropsy.

This Test Guideline describes the modified MITI test (II). This test permits the measurement of the Biochemical Oxygen Demand (BOD) and the analysis of residual chemicals in order to evaluate the inherent biodegradability of chemical substances which have been found by the Standard MITI Method (I) to be low degradable.

An automated closed-system oxygen consumption measuring apparatus (BOD-meter) is used. Chemicals to be tested are inoculated in the testing vessels (six bottles with different quantities of test chemical) with micro-organisms. In order to check the activity of the inoculum, the use of control substances (aniline, sodium acetate or sodium benzoate) is desirable. During the test period, the BOD is measured continuously. Biodegradability is calculated on the basis of BOD and supplemental chemical analysis, such as measurement of the dissolved organic carbon concentration, concentration of residual chemicals, etc. The BOD curve is obtained continuously and automatically for 14 to 28 days. After the 14 to 28 days of testing, pH, residual chemicals and intermediates in the testing vessels are analysed.
