Some recent literature in Green Chemistry of Interest

Having been away from the blogosphere for a time, some recent interesting articles relating to the development of Green Chemistry and Sustainablity are highlighted here:

Sustainable from the very beginning: rational design of molecules by life cycle engineering as an important approach for green pharmacy and green chemistry
from RSC - Green Chem. latest articles by Klaus Kummerer
Taking into account the full life cycle of chemicals will lead to a different understanding of the full functionality necessary for a chemical. Examples are presented to underline the feasibility and the economic potential of the approach benign by design.Klaus Kummerer

Integral resource management by exergy analysis for the selection of a separation process in the pharmaceutical industry
from RSC - Green Chem. latest articles by H. Van Langenhove
Overall natural resource intake (MJexergy mol-1) for (2R,3R)-3-(3-methoxyphenyl)-N,N-2-trimethylpentanamine-an intermediate in Tapentadol production-manufacturing and isolation through crystallisation or chromatography has been quantified.J. Dewulf, G. Van der Vorst, W. Aelterman, B. De Witte, H. Vanbaelen, H. Van Langenhove

What is a green solvent? A comprehensive framework for the environmental assessment of solvents
from RSC - Green Chem. latest articles by Konrad Hungerbuhler
This article addresses the question of how to measure how "green" a solvent is. We propose a framework that covers major aspects of the environmental performance of solvents over the full life-cycle, and also includes health and safety issues.Christian Capello, Ulrich Fischer, Konrad Hungerbuhler

Also a recent piece of news in C&EN (ACS) from China on environmental legislation and control:
China Admits Setback
Premier vows country will try harder to meet environmental goals
Jean-François Tremblay
Chinese Premier Wen Jiabao admitted last week that his country failed in 2006 to meet the environmental emissions and energy efficiency targets that it had set in 2005. But he vowed that China will stick to its medium-term targets for 2010.

Wen addresses China's parliament.

Wen was speaking in Beijing at the opening session of the annual meeting of the National People's Congress, China's parliament. Facing 3,000 parliamentarians and the world media, his address could not have been more public.
In 2006, China reduced its energy consumption per unit of gross national product by 1.2%, falling far short of the 4.0% target, he said. Instead of coming down 2.0%, emissions of sulfur dioxide increased 1.8%, and chemical oxygen demand, a measure of water pollution, grew by 1.2%.
Under its 11th national five-year plan, which ends in 2010, China aims to reduce its emissions of major pollutants by 10% and to raise its economic energy efficiency by 20%. "Meeting these mandatory targets cannot be revised, so we must work resolutely to meet them," Wen told delegates.
Partly to meet environmental goals, China will try to curb its economic growth to 8.0% in 2007, down from the 10.7% it achieved last year. In addition, the premier said the country will close smaller coal-fired power plants as well as substandard facilities producing cement, aluminum, ferrous alloys, coke, and calcium carbide.
China has difficulty enforcing national environmental standards, because the country operates in a decentralized manner that allows municipal and provincial officials to interpret Beijing's directives in their own way.
China's State Environmental Protection Agency
reports on its website that its outspoken deputy director, Pan Yue, is urging a change in Chinese laws to correct this situation. Arguing that government officials are involved in the most severe cases of environmental violations, he is calling for new rules that would permit the central government to punish officials who fail to enforce national standards.
