United Nations Framework Convention on Climate Change
ARTICLE 2: OBJECTIVE
The ultimate objective of this Convention and any related legal instruments that the
Conference of the Parties may adopt is to achieve, in accordance with the relevant
provisions of the Convention, stabilization of greenhouse gas concentrations in
the atmosphere at a level that would prevent dangerous anthropogenic
interference with the climate system. Such a level should be achieved within a
time-frame sufficient to allow ecosystems to adapt naturally to climate change, to
ensure that food production is not threatened and to enable economic development
to proceed in a sustainable manner.

Notes:
1. Base year consists of emissions of CO2, CH4 and N2O in 1990, and of HFCs, PFCs and SF6 in 1995.
2. Emissions are presented as carbon dioxide equivalent in line with international reporting and carbon trading. To convert carbon dioxide equivalent to carbon divide figures by 44/12.
3. Net purchase/sales is the difference between units surrendered and units allocated.

January 2010. The new Garden Site – lots of work ahead
January 2010. The new Garden Site looking from the river to the
northeast
February 2010. Panic: Despite promises that we would own the
place by early January, the council still haven’t sent any
documents
March 2010. Still no progress - we plough ahead anyway
March 2010. Disaster! The Council now orders us to have a full
contaminated land survey done – a month long process – despite
the fact that the allotment land has only ever been used for hanging
washing on as the town’s Drying Green. And the growing season’s
started! And we still don’t own the land!!
We have to get off the land just as the growing season is getting
under way, will the project ever get off the ground? The Council
contact us to start conveyancing procedures the day after a front
page article in the local paper – meantime our team has to spend
its time doing odd jobs around the place.
May 2010. success at last! We get our permissions and it’s all
systems go to get ready for allotment holders.
Raised beds are constructed for those who have difficulty kneeling
or bending. The raised bed allows you to sit down to garden –
perfect for those who use wheelchairs! Filled with compost and
good quality top soil and sprinkled with Scottish rock dust, they
allow for a very high quality and yield from the area.
We lay a path using waste building materials from around the site.
Some 15 tonnes of hedge trimmings are laid around the site, saving
them from landfill, looking attractive, and smelling heavenly of pine.
May 21st. It’s Opening Evening, and allotment-holders are invited
in. From 8 months old to 80 years, a new community forms as we
dig the soil, drink the wine and chew the fat together. The Land is
Ours!
Allotment holders work from 7.30am
the next morning, and all weekend,
to catch up with the season.
June 2010. Just 2 weeks after opening and our Allotment holders have
done us proud and worked ever so hard to get plants into the ground
and growing. We are all thrilled to see such activity and this is what
we’ve all been working at for so long. Well done everybody!
