This screening Test Guideline describes the effects of a test chemical on male and female reproductive performance. It has been updated with endocrine disruptor endpoints, in particular measure of anogenital distance and male nipple retention in pups and thyroid examination.
The test substance is administered in graduated doses to several groups of males and females. Males should be dosed for a minimum of four weeks. Females should be dosed throughout the study, so approximately 63 days. Matings "one male to one female" should normally be used in this study. This Test Guideline is designed for use with the rat. It is recommended that each group be started with at least 10 animals of each sex. Generally, at least three test groups and a control group should be used. Dose levels may be based on information from acute toxicity tests or on results from repeated dose studies. The test substance is administered orally and daily. The results of this study include clinical observations, body weight and food/water consumption, oestrous cycle monitoring, offspring parameters observation/measurement, thyroid hormone measurement, as well as gross necropsy and histopathology. The findings of this toxicity study should be evaluated in terms of the observed effects, necropsy and microscopic findings. Because of the short period of treatment of the male, the histopathology of the testis and epididymus should be considered along with the fertility data, when assessing male reproductive effects.
The 2011 Green Growth Strategy provided initial guidance to governments on how to achieve economic growth and development, while preventing costly environmental damage and inefficient resource use. What progress have countries made in aligning economic and environmental priorities since 2011? This report attempts to evaluate this progress and highlight where there is broad scope to heighten the ambition and effectiveness of green growth policy. It draws lessons from green growth mainstreaming across the OECD’s work programme, notably in terms of how governments can maximise institutional settings to seize economic opportunities surrounding the transition to a green economy, and considers ways to enrich the Green Growth Strategy based on work undertaken since its launch.
The programme (or BioPesticides including microbials - bacteria, algae, protozoa viruses, fungi -, pheromones and semiochemicals, macrobials/invertebrates such as insects and nematodes, and plant extracts/botanicals) helps member countries to harmonise the methods and approaches used to assess biological pesticides.
Climate change is giving rise to diverse risks, ranging from changing incidences of tropical diseases to increased risks of drought, varying widely in their potential severity, frequency and predictability. Governments must integrate the management of these climate risks into policy making if they are to successfully adapt to a changing climate. Economic analysis has a vital role to play in supporting these efforts, by identifying costs and benefits and supporting decision-making for an uncertain future. However, this analysis needs to be adapted to the institutions, policies and climate risks in a given country. Building on the experience of OECD countries, this report sets out how the latest economic evidence and tools can enable better policy making for adaptation.
This report produced in co-operation with the International Energy Agency (IEA), the International Transport Forum (ITF) and the Nuclear Energy Agency (NEA) identifies the misalignments between climate change objectives and policy and regulatory frameworks across a range of policy domains (investment, taxation, innovation and skills, trade, and adaptation) and activities at the heart of climate policy (electricity, urban mobility and rural land use).
Outside of countries’ core climate policies, many of the regulatory features of today’s economies have been built around the availability of fossil fuels and without any regard for the greenhouse gas emissions stemming from human activities. This report makes a diagnosis of these contradictions and points to means of solving them to support a more effective transition of all countries to a low-carbon economy.
This major report produced in co-operation with the International Energy Agency (IEA), the International Transport Forum (ITF) and the Nuclear Energy Agency (NEA) identifies the misalignments between climate change objectives and policy and regulatory frameworks across a range of policy domains (investment, taxation, innovation and skills, trade, and adaptation) and activities at the heart of climate policy.
The International Tax Dialogue (ITD) is organising its 6th global conference at the OECD. This year’s conference will focus on Tax and the Environment, an issue of growing importance and of direct relevance in the lead up to the COP21 meeting taking place later in the year. The ITD is a joint initiative of the EC, IDB, IMF, OECD, World Bank and CIAT.
This paper refines indicators to measure innovation in environment-related technologies, drawing on recent methodological advances that allow a more accurate assessment of environment-related innovation in a broader range of countries. Three indicators are discussed: an indicator of technology development; an indicator of international collaboration in technology development and an indicator of technology diffusion.
Energy is a critical input into the production and consumption patterns that support economic and social wellbeing. However, many forms of energy use contribute to the environmental and climate challenges societies face today. Taxation is a key tool by which governments can influence energy use to contain its environmental impacts. This report provides a systematic analysis of the structure and level of energy taxes in OECD and selected other countries; together, they cover 80% of global energy use.
This report builds on the 2013 edition of Taxing Energy Use, expanding the geographic coverage of the 2013 data set to include Argentina, Brazil, China, India, Indonesia, Russia and South Africa. The report describes energy use, taxation and pricing in these countries and presents detailed graphical profiles of the structure of energy use and taxation for each.
The analysis reveals large differences in the taxation of energy across countries, although common patterns emerge. Transport taxes are considerably higher than in other sectors, where fuels that cause considerable harm for the environment and human health are often taxed at very low – or zero – rates. With few exceptions, countries' energy taxes do not harness the full power of taxes to reduce pollution and combat climate change.
Proposals to increase environmentally related taxes are often challenged on competitiveness grounds. The concern is that value creation in certain sectors might decline domestically if a country introduces environmentally related taxes unilaterally. This paper provides evidence on the short-term competitiveness impacts of the German electricity tax introduced unilaterally in 1999.
