CFCs to HFCs: frying pan to fire
When the dramatic discovery of the ozone hole in 1986 forced the
banning of Chlorofluorocarbons (CFC's), the refrigeration industry
switched to hydrofluorocarbons (HFC's). HFC's don't destroy the ozone
like CFC's can. But they do cause global warming. Indeed, some HFC
gases are up to 11,000 times more harmful to the climate than carbon
dioxide (CO2), your garden variety greenhouse gas.
Solution: Greenfreeze
To highlight the madness of this switch from CFC's to HFC's and
show how it should be
done, Greenpeace launched the concept of Greenfreeze in 1992. We met
two
scientists who pointed out how to avoid HFC's altogether. We found an
old fridge factory, appealed to our supporters to pre-order enough
units to finance a refit, helped build the market and Greenfreeze was
born.
It uses natural gases so avoids both depleting the ozone layer and
fuelling global warming. The chemical industry said it would never work
and the big refrigeration users lined up with their friends in the
industry to dismiss our claims.
Well that was then, and this is now. Today there are over 100
million Greenfreeze refrigerators in the
world, produced by all the major European, Chinese, Japanese and Indian
manufacturers. It is now available in most major markets with the
exception of North America.
While Greenfreeze technology gradually gained a foothold in the
domestic market in the late 1990's, large commercial users continued to
use refrigeration that causes global warming. In the run up to the
Sydney Olympics in 2000 we targeted big refrigeration users such as
Unilever, Coke and McDonalds, all Olympic sponsors, to live up to the
guidelines of the green games which excluded HFC's.

Coke in the spotlight
Coke caved in after a concerted online campaign
(CokeSpotlight.org)
before the 2000 Olympics to buy green refrigeration for new units.
Before the start of the games all three companies we had targeted
announced phase out
plans for damaging refrigeration technologies by the time of the 2004
Olympics.
Today Coke plans to install no less than
6,350
climate-friendly coolers and vending machines in the Olymic Games
venues in Beijing and six co-host cities throughout China. Calculated
based on an expected ten year life span of the units, they reduce
greenhouse gas emissions by approximately 4,500 metric tons.
This is
the first time that 100 percent of the coolers and vending machines
provided by Coca-Cola to all Olympics venues will feature HFC-free
insulation, and HFC-free natural refrigerant. For good measure, Coke
has also added a proprietary technology called Energy Management System
(EMS) that improves energy efficiency by more than 35 percent.
"This
innovative approach of combining natural refrigerants and energy
efficient technology is a great example of how a business can work
with other stakeholders to reduce greenhouse gas emissions. We hope
Coca-Cola's efforts can accelerate industry-wide actions to combat
climate change," said LO Sze Ping, Campaign and Communications
Director of Greenpeace China.
What's next for HFC's
Not to be outdone by Coca-Cola, the
Whitehouse
is rumoured
to be
planning an announcement at next week's UN meeting on ozone depleting
substances (the Montreal Protocol), proposing aggressive targets to
phase-out HFC gases.
Left unchecked, HFC's are expected to
contribute up to 5.2 percent of the world's global warming emissions by 2050.
It will take much more than public
pronouncements to tackle the climate crisis. But as the Montreal Protocol comes to it's 20th anniversary, and the story of
Greenfreeze demonstrates, creativity, vigilance and a "can do!"
attitude can transform even the most familiar/dire characters and
situations.
