This report provides a new perspective to the nature of urban sprawl and its causes and environmental, social and economic consequences. This perspective, which is based on the multi-dimensionality of urban sprawl, sets the foundations for the construction of new indicators to measure the various facets of urban sprawl.
The report uses new datasets to compute these indicators for more than 1100 urban areas in 29 OECD countries over the period 1990-2014. It then relies on cross-city, country-level and cross-country analyses of these indicators to provide insights into the current situation and evolution of urban sprawl in OECD cities.
In addition, the report offers a critical assessment of the causes and consequences of urban sprawl and discusses policy options to steer urban development to more environmentally sustainable forms.

A new chemical process can liquify plastic. The next challenge? Creating a machine that can recycle the sludge on an industrial scale
SmarterHouse, a project of the American Council for an Energy-Efficient Economy, is a complete and up-to-date guide available on energy savings in the home.
Following a review of measures to tighten up the building shell itself, the site focuses on the things you put in it your home—including major appliances, heating equipment, air conditioning, lighting, and electronics—and how the energy use of those products can be reduced.
If you’re about to buy a new appliance or heating system, you’ll be most interested in the tips on what to look for when buying new equipment. Otherwise, look for guidance on how to get the best energy performance through operation and maintenance of the products you already own.
For further information and updates, they’ve included links directing you to valuable resources provided by the government, trade associations, and other sources.

If we want to overcome the systemic issues behind today’s problems, then we need to change the thinking that led to them to begin with. The status quo of how we are taught to think is linear and often reductionist. We learn to break the world down into manageable chunks and see issues in isolation of their systemic roots.

Two new papers describe publicly accessible web-based tools for exploring environmental chemicals and predicting their risk. These resources will help health policymakers to make faster and more accurate decisions about chemical safety and the need for remediation efforts.
The Conditional Toxicity Value (CTV) Predictor, was described in the May issue of Environmental Health Perspectives. The tool’s web portal allows users to rapidly obtain chemical toxicity values, which are predicted using a collection of statistical models.
The second tool was reported May 22 in the journal Bioinformatics. The ChemMaps.comwebserver allows users to easily browse, navigate, and mine chemical space. ChemMaps.com includes DrugMap, which lists more than 8,000 drugs, and EnvMap, which lists more than 47,000 chemicals of relevance to NIEHS and the U.S. Environmental Protection Agency (EPA).
