Reforesting Efforts
  • Planting the wrong kind of trees, such as
    monocultures of eucalyptus or pine where they are
    not native species, can devastate the lands of
    the local people.
  • A practical solution is to plant tough,
    fast-growing native tree species which begin
    rebuilding the land
  • Reforestation, if several native species are used
    can provide other benefits in addition to
    financial returns, including restoration of the
    soil, rejuvenation of local flora and fauna, and
    the capturing and sequestering of 38 tonnes of
    carbon dioxide per hectare per year

Worldly Data
  • Total Average Deforested per year 12,599,000
    Hectares
  • 2000-2005 Deforestation 62,995,000 Hectares
  • Carbon Sequestration from Native Species 38
    tonnes per hectare per year
  • Total Sequestration potential over 5 years
    2,393,810,000 tonnes.

Costs
  • Mitigation costs through forestry can be quite
    modest (US0.1US20 / metric ton carbon dioxide)
    in some tropical developing countries
  • As little as 90 US will plant 900 trees, enough
    to annually remove as much carbon dioxide as is
    annually generated by the fossil-fuel usage of an
    average United States resident

US Sequestration
  • In the United States in 2004 (the most recent
    year for which EPA statistics are available),
    forests sequestered 10.6 of the carbon dioxide
    released in the United States by the combustion
    of fossil fuels. Urban trees sequestered another
    1.5 To further reduce U.S. carbon dioxide
    emissions by 7, as stipulated by the Kyoto
    Protocol, would require the planting of "an area
    the size of Texas 8 of the area of Brazil
    every 30 years", according to William H.
    Schlesinger, dean of the Nicholas School of the
    Environment and Earth Sciences at Duke
    University, in Durham, N.C.. Carbon offset
    programs are planting millions of fast-growing
    trees per year to reforest tropical lands, for as
    little as 0.10 per tree over their typical
    40-year lifetime, one million of these trees will
    fix 0.9 teragrams of carbon dioxide

What are we doing?
  • ABB built the worlds first commercial CO2
    capture facility at its Shady Point, Oklahoma
    coal-fired power plant. It captures 200 tons of
    CO2 a day from the plants flue gas, which is
    purified, liquefied, and sold to the food
    products industry.
  • AEP, under DOEs Climate Challenge Tree Planting
    Project, has planted 21,914 acres with nearly 19
    million mixed hardwood and conifer trees at a
    cost of approximately 5.7 million. Projected CO2
    sequestration is 4.7 million metric tons over the
    term of the project. In a separate initiative in
    Louisiana, AEP has planted 9,784 acres with
    nearly 3 million bottomland hardwood trees at a
    cost of 6.25 million. Projected carbon
    sequestration is over 4.4 million metric tons.
  • Royal Dutch/Shell is a member of the CO2 capture
    project CO2 Capture Research Project, an
    international effort by seven of the worlds
    leading energy companies.

  • Pacific Gas and Electric Company has submitted a
    proposal to the California Public Utilities
    Commission (CPUC) for a new and innovative
    environmental program that will allow interested
    customers to contribute toward a cleaner
    California.   This voluntary program would be
    available to most of PGEs residential and
    business customers.
  • Through the Climate Protection Program,
    customers can choose to sign up and pay a small
    premium on their monthly utility bill which will
    fund independent environmental projects aimed at
    removing carbon dioxide from the air.  To read

  • In 2004 Weyerhaeuser improved its process for
    inventorying GHG emissions and the carbon stored
    in its forests and products.  The companys
    operations sequestered approximately 26 million
    metric tons of carbon dioxide equivalents and
    emitted approximately 7 million tons from the use
    of fossil fuels and other activities.  This
    effectively sequestered 19 million metric tons of
    carbon dioxide equivalent or 0.5 metric tons of
    carbon equivalents per ton of production, an
    improvement of approximately 18 over 2003.
