"Greenwashing" - and how to avoid it.

Article by Jennifer Woofter: Strategic Sustainability Consulting.

"The Coalition for Responsible Fire Protection began in 2010 as a healthy discussion about how to balance environmental sensitivity with the need to preserve life and property. many large firms now expect or even demand more environmentally responsible products and systems, which will reflect and support their own environmental commitments. While small steps have been taken to "green" the fire protection industry, to date the Coalitiion believes it has been a mostly cosmetic exercise." ..... to read more click here!

Climate Crisis - The 21 Gigatonne Time Bomb (Nature Inc)

THE 21 GIGATONNE TIMEBOMB: Broadcast in May 2011 on BBC World News to 300 million homes this programme explores the much-neglected issue of what to do about the super-greenhouse gases?

Under the 1987 Montreal Protocol, CFCs and other so-called ozone-depleting chemicals are outlawed, but their Hydrofluorocarbon (HFC) replacements – while harmless to the ozone layer – are powerful greenhouse agents.

According to the Intergovernmental Panel on Climate Change fully one fifth of the greenhouse effect by midcentury will be ascribed to these ozone-friendly but "super greenhouse gases" used in refrigeration and air conditioning.

There are alternatives – principally hydrocarbons - commercially available now (but also ammonia, carbon dioxide and water), but in some countries, they are considered a fire hazard, and are restricted. Many countries allow their usage provided safety standards are followed.

Meanwhile companies such as Dupont are developing a new generation of refrigerants, such as R-1234yf, that they claim have an minimal impact on climate change and are only "mildly flammable" (overlooking extremely toxic combustion byproducts including the lethal hydrogen fluoride).

But they are not yet commercially available, and will be far more expensive than hydrocarbons and high GWP HFCs when they come to market. Different countries have different stances on how to deal with HFC issue. This documentary examines this interesting story from different perspectives.

Aviation Takes Action on Ozone and Climate Protection

Montreal, 16 September 2011 At their working group meeting last month, the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer heard from the Protocol's Halons Technical Options Committee (HTOC) and the International Civil Aviation Organization (ICAO) on yet another successful step in phasing out halons in fire extinguishers on aircraft.
Halons are among the most potent destroyers of the stratospheric ozone layer and are also potent greenhouse gases. Phasing out halons used in fire extinguishers on aircraft has been a difficult challenge because of their effectiveness in fire fighting that in turn helps to increase the safety of passengers. However, in 2003 the Parties to the Montreal Protocol asked the Ozone Secretariat of the United Nations Environment Programme (UNEP) and its technical experts to begin to work with ICAO to look into the possibility of modifying the regulatory requirements that mandate the use of halons on new aircraft without compromising the health and safety of airline passengers.

Thanks to the assistance of the Halon Technical Option Committee (HTOC), ICAO has amended two of its technical Annexes containing standards related to aircraft operations and airworthiness. Both Annex 6 - Operation of Aircraft - and Annex 8 - Airworthiness of Aircraft - have been amended to include a related environmental requirement.

"This was a landmark agreement that resulted from successful collaboration between two multilateral agreements, one for ozone protection and the other for international aviation. The Parties to the Montreal Protocol have been focusing their attention on enhancing collaboration and synergies with other international agreements and regimes. The Parties can be proud that the Montreal Protocol has again managed to contribute to both ozone and climate protection, this time through synergy in civil aviation sector, said Marco Gonzalez, the Executive Secretary of the Ozone Secretariat.

"The agreement to phase out halons was another step forward by the Organization to further strengthen the ability to minimize the impact of air transport operations on the environment. The assistance of the HTOC and UNEP to reach this agreement was instrumental in realizing this achievement, and we look forward to continuing this important inter-agency cooperation to better serve the international community," said ICAO's Secretary General, Raymond Benjamin.

"The progress made by ICAO is important for the ozone layer protection. It is also significant as it demonstrates the commitment of ICAO to the environmental protection. For the first time an operative annex to the Chicago Convention was changed to respond to an environmental concern. This is a win-win for the ozone layer and civil aviation. The United States congratulates the HTOC, ICAO and the Ozone Secretariat, said Cindy Newberg, Chief of the Alternatives and Emissions Reduction Branch of the US Environmental Protection Agency (USEPA).

ICAO will continue to monitor the research and development of halon alternatives to ensure that the target dates can be met and will follow up on research into a viable halon alternative for cargo area fire extinguishing systems.

"We note that there is still much to be done to make sure that alternatives are identified and can be effectively used, to develop a viable path forward for cargo bays, and ensure that it does not become necessary to pursue use of the essential use provisions to support civil aviation on-going needs. We encourage the HTOC and Ozone Secretariat to continue to work with ICAO," added Ms. Newberg.

"[We] would like to thank the HTOC in particular for its ongoing work with ICAO bodies in supporting the reductions in mandating the use of halons in new air frames. We would also like to thank the ICAO Secretariat for facilitating this excellent outcome and can agree that HTOC can continue its work as needed with ICAO bodies," said Annie Gabriel from the Department of Sustainability, Environment, Water, Population and Communities of Australia.

Notes to Editors:
Nearly three decades ago, atmospheric scientists warned that the annual appearance of the Antarctic ozone hole and the probability of increasing depletion of the stratospheric ozone layer had serious consequences for all life forms. This came after discoveries in the mid-1970s that some man-made chemicals could destroy ozone, resulting in increased ultraviolet radiation reaching the Earth.

Although ozone is a small component of the atmosphere, the ozone layer plays a vital role in shielding life on Earth from harmful ultraviolet (UV-B) radiation from the sun. Human exposure to UV-B is known to increase the risk of skin cancer, cataracts, and a suppressed immune system. UV-B exposure can also damage terrestrial plant life, single-cell organisms and aquatic ecosystems.

The evidence that human activities were destroying the stratospheric ozone layer was compelling. Emissions of certain man-made chemicals used in many products such as the halons used as fire extinguishants in aircraft were reaching the stratosphere, between 10-16 kilometres and up to 50 kilometres above the Earth's surface, and destroying ozone molecules. With the appearance of the ozone hole, many countries joined efforts for the first time to combat this global environmental threat. All countries of the world have ratified the landmark international environmental treaty, the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer. Parties to the Montreal Protocol are committed to eliminating production of ozone-depleting substances by meeting specific phase-out deadlines.

ICAO is specialized agency of the United Nations, ICAO was created in 1944 to promote the safe and orderly development of international civil aviation throughout the world. It sets standards and regulations necessary for aviation safety, security, efficiency and regularity, as well as for aviation environmental protection. The Organization serves as the forum for cooperation in all fields of civil aviation among its 190 Member States.
