Paper Production
In South Africa paper production is done via dedicated forests owned
and managed by the paper and pulp manufacturers. Paper manufacturers
plant on average 3 trees for every tree cut down. The trees vs. paper
calculation is shown for interest and is not added to the total
footprint or offset. This is in accordance to international reporting
principles.
Paper consumption Input from Xerox 1 tree equals 14 reams or 7000 sheets, 410 reams equals 1 ton.

Treeplanting
'Climate
scientists believe that human-induced global deforestation is
responsible for 18-25% of global climate change. The United Nations,
World Bank and other leading nongovernmental organizations are
encouraging reforestation, avoided deforestation and other projects
that encourage tree planting to mitigate the effects of climate change.
Trees sequester carbon dioxide through photosynthesis, converting
carbon dioxide and water into molecular dioxygen (O2) and plant organic
matter, such as carbohydrates (e.g., cellulose). Hence, forests that
grow in area or density and thus increase in organic biomass will
reduce atmospheric CO2 levels. (Carbon dioxide is released as CO2 if a
tree or its lumber burns or decays, but as long as the forest is able
to grow back at the same rate as its biomass is lost due to oxidation
of organic carbon, the net result is carbon neutral.) In their 2001
assessment, the IPCC estimated the potential of biological mitigation
options (mainly tree planting) is on the order of 100 Gigatonnes of
carbon dioxide (cumulative) by 2050, equivalent to about 10% to 20% of
projected fossil fuel emissions during that period.

In
order to have a practical and easy calculator the calculations are
based on a medium sized petrol car. In accordance with the definitions
and factors from the GHG Protocol Mobile Combustion Tool this car would
emit 0.22 kg CO2 per km. In an average company some employees would
drive a smaller where others drive larger cars and a medium sized car
would closely approximate the overall picture. This emission factor can
not be applied to off road agricultural or delivery vehicles. Please
follow the principles of the GHG reporting protocol (now also available
as SANS 14064-1:2006 Specification with guidance at the organizational
level for quantification and reporting of greenhouse gas emissions and
removals) to guide you should you/your company need a comprehensive
calculation.
