World clean energy coalition: The Cercle Mondial du Consensus (CMDC
or World Circle of the Consensus) is a coalition working toward greater use of
clean energy options and reduction of CO2 emissions. A World Clean Energy
Conference is planned in November 1991 in preparation for the 1992 UNCED Earth
Summit in Brazil. CMDC publishes a newsletter as well as reports of its previous
meetings. Contact CMDC, Kellerweg 38, CH-8055 Zurich, Switz. (tel: 411-463-9252;
Japan pushes environmental technologies: Over the last two years
Japanese industry and government have invested hundreds of millions of dollars
in an attempt to establish world dominance in the development of environmental
technologies. The government's Research Institute of Innovative Technology for
the Earth (RITE), to open next year in Kansai Science City, will develop
biological and chemical techniques for absorbing CO2 and for developing CFC
substitutes (Nature, pp. 266-267, Mar. 28, 1991). Two microbiologists at
Tokyo University of Agriculture and Technology have developed a prototype "biosolar
reactor," in which genetically engineered bacteria remove CO2 from air with
the assistance of sunlight distributed by optical fiber cables (ibid.,
p. 267). See also "Japan's Climate Policy: An Overview" (Global
Environ. Change Rep., pp. 1-3, Apr. 19, 1991) for more on research and
India joins protocol: The Indian cabinet has approved the
Environment Ministry's proposal for India to join the Montreal Protocol (Intl.
Environ. Rptr., pp. 188-189, Apr. 10, 1991). The action was taken after
industrialized countries agreed to revise sections of the protocol concerning
developing countries last June. India will now be eligible for direct funds and
loans to assist CFC phase-out.
Urban CO2 Project: About a dozen cities around the world are
cooperating in a ten-year program to develop approaches for offsetting CO2
emissions in urban areas, managed by the International Council for Local
Environmental Initiatives. In the two-year first phase, participating cities
will prepare comprehensive plans and adopt policies. Later, plans will be
implemented, and the policy and technical framework shared with other cities.
See Global Environ. Change Rep., pp. 3-4, Apr. 19, 1991, or contact the
Council at 736 Massachusetts Ave., Cambridge MA 02139 (617-491-6124). See
Reports, this Global Climate Change Digest issue--May 1991, for plans
developed by one participant, the city of Toronto.
"Economic Considerations Enter Fray over Global Climate Change
Policies," P.S. Zurer, Chem. Eng. News, pp. 7-13. Based on
discussion at a conference on the economic costs of climate change (Washington,
D.C., Dec. 1990), this survey explains the basic concepts involved (top-down vs.
bottom-up analyses, cost-benefit analyses, demand-side vs. end-use measures for
reducing greenhouse emissions) and recent major studies on the topic. The
conference suggested that cost-benefit analysis alone is inadequate to address
global climate change policies. The scientific uncertainty of the extent and
impacts of change further complicate economic and technological analyses.
