Scientists at Massachusetts Institute of Technology have completed what is believed to be the first major study to assess the greenest way of drying your hands.
The research paper compared the seven most common drying methods in public toilets and concludes that paper towels and warm air hand dryers have the highest environmental toll ? generating 70% more carbon emissions than the newest technology on the market, the cold air-driven hand dryer from UK manufacturer Dyson, which also commissioned the paper.
Major American environmental groups have dodged the subject of population control for decades, wary of getting caught up in the bruising politics of reproductive health.

Yet, virtually alone, the Center for Biological Diversity is breaking the taboo by directly tying population growth to environmental problems through efforts like giving away condoms in colorful packages depicting endangered animals. The idea is to start a debate about how overpopulation crowds out species and hastens climate change ? just when the world is welcoming Baby No. 7 Billion.
The mass installation on 600 homes in Broxtowe and Aspley is one of the largest to be carried out in the UK in a single domestic scheme. The energy savings are thought to total around £72,000 a year. The solar industry said the government's plans to cut feed-in tariffs by over 50% in the next six weeks would devastate the number of installations on homes, schools and small businesses

The Second Edition of the Buying Green! Handbook has just been
published by the European Commission.
The new Handbook provides detailed guidance for greening each step of
the procurement process. A number of revisions have been made since the
2004 edition, including:
* Greater attention to the application of GPP to services and works
* Expanded sections on selection and award criteria, technical
specifications, LCC and contract clauses
* New examples of contracts drawn from across the EU-27
* Specific sectoral guidance on electricity, construction, timber and
food and drink
The Handbook is available on the EU GPP website along with a shorter summary document aimed at policy-makers and others who may not have a detailed knowledge of procurement or GPP.
Global population trends result from varying levels of population growth and decline among countries. This informative video provides a simple and compelling overview of population trends that have created a world of 7 billion people.
Population Reference Bureau informs people around the world about population, health, and the environment, and empowers them to use that information to advance the well-being of current and future generations.
