    Financing climate change action

    Limiting climate change to 2°C requires a major shift in investment patterns towards low-carbon, climate resilient options. Our report "Green Investment Banks: Scaling-up Private Investment in Low-carbon, Climate-Resilient Infrastructure" is now available.

    Reforming Economic Instruments for Water Resources Management in Kyrgyzstan

    This report presents recommendations on the reform of economic instruments for water resources management in Kyrgyzstan, specifically on tariffs for urban water supply and sanitation (WSS) and irrigation water, pollution charges, surface water abstraction charges for enterprises (consumptive and non-consumptive uses), specific land tax rates for the Issyk-Kul biosphere reserve, as well as taxes and customs duty on products contributing to water pollution. For each instrument, alternative reform options are identified and assessed, and preferred options put forward, with an action plan.

    Car purchase tax: green tax reform in Israel

    The car tax in Israel has been historically the highest compared to any other country in the world, except for Denmark. The vehicle purchase tax was adjusted in 2005, 2009 and 2013. The Israeli experience sets a precedent for a tax that takes all pollutants into account.

    Behavioural and Experimental Economics for Environmental Policy

    This project investigates how behavioural economics can inform the design of “norm-based” environmental policies and “behaviourally robust” markets for ecosystem services. This work is part of a broader effort of a project that seeks to identify areas where behavioural economics can have the greatest impact on environmental policy design. The BEEP database is now available.

    Test No. 478: Rodent Dominant Lethal Test

    The purpose of the Dominant lethal (DL) test is to investigate whether chemical agents produce mutations resulting from chromosomal aberrations in germ cells. In addition, the dominant lethal test is relevant to assessing genotoxicity because, although they may vary among species, factors of in vivo metabolism, pharmacokinetics and DNA-repair processes are active and contribute to the response. Induction of a DL mutation after exposure to a test chemical indicates that the chemical has affected germinal tissue of the test animal.

    This modified version of the Test Guideline reflects more than thirty years of experience with this test and the potential for integrating or combining this test with other toxicity tests such as developmental, reproductive toxicity, or genotoxicity studies; however due to its limitations and the use of a large number of animals this assay is not intended for use as a primary method, but rather as a supplemental test method which can only be used when there is no alternative for regulatory requirements.

    Test No. 458: Stably Transfected Human Androgen Receptor Transcriptional Activation Assay for Detection of Androgenic Agonist and Antagonist Activity of Chemicals

    This Test Guideline describes an in vitro assay providing the methodology of Stably Transfected Transactivation to detect Androgen Receptor Agonists and Antagonists (AR STTA assays). The TA assay using a reporter gene technique is an in vitro tool that provides mechanistic data. The assay is used to establish signal activation or blocking of the androgen receptor caused by a ligand. Some chemicals may, in a cell type-dependent manner, display both agonist and antagonist activity and are known as selective androgen receptor modulators. Following the ligand binding, the receptor-ligand complex translocates to the nucleus where it binds specific DNA response elements and transactivates a firefly luciferase reporter gene, resulting in an increased cellular expression of the luciferase enzyme. Luciferin is a substrate that is transformed by the luciferase enzyme to a bioluminescence product that can be quantitatively measured with a luminometer. Luciferase activity can be evaluated quickly and inexpensively with a number of commercially available test kits. The test system provided in this Test Guideline utilises the AR-EcoScreenTM cell line.

    Test No. 243: Lymnaea stagnalis Reproduction Test

    This Test Guideline is designed to assess effects of prolonged exposure to chemicals on the reproduction and survival of the hermaphrodite freshwater snail Lymnaea stagnalis (the Great Pond Snail). Reproducing adults of L. stagnalis are exposed to a concentration range of the test chemical and monitored for 28 days for their survival and reproduction (number of egg clutches). As additional information, the number of eggs per clutch may also be determined. Adult shell length increase may also be measured. The toxic effect of the test chemical on the cumulated number of clutches produced per individual-day is expressed as ECx by fitting an appropriate regression model to the data in order to estimate the concentration that would cause x% reduction in the reproductive output. Alternatively, the toxic effect of the test chemical can be expressed as the No Observed Effect Concentration and Lowest Observed Effect Concentration (NOEC/LOEC) values. Both ECx and NOEC/LOEC can be determined from a single study.

    Test No. 242: Potamopyrgus antipodarum Reproduction Test

    The Potamopyrgus antopodarumon reproduction test is designed to assess potential effects of prolonged exposure to chemicals on reproduction and survival of parthenogenetic lineages of the freshwater mudsnail Potamopyrgus antipodarum. Adult female P. antipodarum are exposed to a concentration range of the test chemical. The test chemical is dispersed into the reconstituted dilution water, added to test beakers, and adult snails are subsequently introduced into the test beakers. When testing “difficult chemicals” (i.e. volatile, unstable, readily biodegradable and adsorbing chemicals) the test can be conducted under flow-through conditions as an alternative to the semi-static design with fixed renewal periods of the medium (see paragraph 29). P. antipodarum survival over the 28 days exposure period and reproduction at the end of the test after 28 days are examined. Reproduction is evaluated by counting the number of embryo in the brood pouch (without distinction of developmental stages) at the end of 28 days exposure. The toxic effect of the test chemical on embryo numbers is expressed as ECX by fitting an appropriate regression model in order to estimate the concentration that would cause x % reduction in embryo numbers or alternatively as the No Observed Effect Concentration and Lowest Observed Effect Concentration (NOEC/LOEC) value (2).
