This brochure provides an overview of OECD work on water. Water policies around the world are in urgent need of reform. OECD work identifies the priority areas where governments need to focus their reform efforts.
A Pollutant Release and Transfer Register (PRTR) is a publicly accessible database or inventory of chemicals or pollutants released to air, water and soil and transferred off-site for treatment. Find out more: What hazardous chemical substances and pollutants are being released to the environment or transferred off-site? How much is being released or transferred off-site over time? Where the releases occur? and by whom?

This work is based on large-scale periodic surveys on Environmental Policy and Individual Behaviour Change (EPIC). The first two rounds involved more than 10 000 households across a number of countries. Five areas where households exert particular environmental pressures are examined: residential energy and water use, transport choices, food consumption, and waste generation and recycling.
The Global Forum was held on 13-14 September 2016; and brought together approximately 200 delegates from both OECD and non-OECD countries to discuss the theme of transparency, and the issues discussed included transparency of mitigation and support.
Anyone else feeling exhausted by all this drum humming about air pollution? Indeed it appears the fumes won’t be dissipating any time soon as we consider the extent to which tyre and brake rubbish exacerbate the problem.
This Performance-Based Test Guideline (PBTG) describes in vitro assays, which provide the methodology of Stably Transfected Transactivation to detect Estrogen Receptor Agonists and Antagonists (ER TA assays). It comprises mechanistically and functionally similar test methods for the identification of estrogen receptor agonists and antagonists and should facilitate the development of new similar or modified test methods. The two reference test methods that provide the basis for this PBTG are: the Stably Transfected TA (STTA) assay using the (h) ERα-HeLa-9903 cell line, derived from a human cervical tumor, and the BG1Luc ER TA assay using the BG1Luc-4E2 cell line, derived from a human ovarian adenocarcinoma. The cell lines used in these assays express ER and have been stably transfected with an ER responsive luciferase reporter gene. The assays are used to identify chemicals that activate (i.e. act as agonists) and also suppress (i.e. act as antagonists) ER- dependent transcription. ER are activated following ligand binding, after which the receptor-ligand complex binds to specific DNA response elements and transactivates the reporter gene, resulting in increased cellular expression of a marker enzyme (e.g. luciferase in luciferase based systems). The enzyme then transforms the substrate to a bioluminescent product that can be quantitatively measured with a luminometer. These test methods are being proposed for screening and prioritisation purposes, but also provide mechanistic information that can be used in a weight of evidence approach.
This event, with involvement from the OECD, on 6-7 September 2016, is of major strategic nature during the Slovak Presidency of the European Council. Its ambition is to improve understanding of the green economy concept, identify conclusions and pathways for transition as well as to involve and mobilise various actors and stakeholders in the discussions of possible future actions.
New deadlines for comments: Draft updated TG 492 on RhCE for eye hazard potential and draft updated performance standards for the validation of similar methods. The deadline for public comments of 3 October 2016.
Climate change is not just about a change in climate towards hotter, wetter, and drier conditions, but also about an increase in the variability of the climate, as well as in the number and severity of extreme events.
This study provides an empirical analysis of the effects of environmental zoning on urban development. It focuses on the case of Natural Regional Parks (NRPs) in France. Of the environmental zoning instruments used in France, NRPs extend over the widest physical area. Three potential side-effects of NRPs on urban development in the regulated area are investigated.
