Alcoa and Alcoa Foundation Conclude Green Works with Increased Global Commitment to Plant Trees and Support Environmental Projects

Alcoa Foundation marked the end of its two-month Green
Works employee volunteer environmental service program today by
increasing its support to the Friends of Vatnajökull National Park in
Iceland and American Forests′ Global ReLeaf, two organizations committed
to environmental replenishment.

Members of the Tree Planting Association of Reydarfjordur, Iceland, joined Alcoa employees in planting 125 trees near the Alcoa Fjardaal aluminum smelter in Reydarfjordur. The tree planting activity concluded the Alcoa Green Works employee environmental service program and supported the company's Ten Million Trees initiative.

Alcoa (NYSE: AA) leaders and employees concluded the Green Works program
in Iceland by planting 125 trees in Reydarfjordur, where the Alcoa
Fjardaál smelter is located. Following the tree planting, Alcoa Iceland
contributed US$700,000 to the Friends of Vatnajökull National Park to
support education, research and environmental projects at Vatnajökull
National Park, the largest national park in Europe.

In addition, Alcoa Foundation added US$200,000 to an American Forests′
Global ReLeaf grant awarded earlier this year that focuses on
environmental restoration projects in Alcoa communities worldwide. The
increase brings the total of the grant to US$800,000. The organization
will assist Alcoa with its Ten
Million Trees initiative over three years.

'Alcoa is committed to sustainability, which includes taking care of our
forests,? said Paula Davis, President, Alcoa Foundation. 'Planting 10
million trees can absorb more than 250,000 metric tons of carbon dioxide
per year and make a significant difference in our quality of life across
the globe.?

This year, Global ReLeaf will award mini
grants to 22 qualified NGO and environmental organizations that will
work with Alcoa employees across the globe to plant trees in their local
communities. Only native tree species will be planted to maintain the
integrity of the environment. The grant will facilitate the planting of
more than 225,000 trees and aligns with Alcoa Foundation′s
sustainability focus to 'Reduce, Recycle and Replenish.?

'Alcoa understands how important forests are for  sustaining  the health
of the planet and the well-being of all its inhabitants,? said Scott
Steen,  CEO, American Forests. 'We are deeply grateful for  Alcoa′s
partnership  with American Forests  to protect and restore these vital
ecosystems.?

About Alcoa′s Ten Million Trees Program

Since 2003, more
than 3.5 million trees have been planted as part of Alcoa′s efforts to
strengthen the communities where Alcoa employees live and work. The Ten
Million Trees initiative encourages employees to take an active role in
conserving flora and fauna, managing biodiversity, enhancing parks and
land use, and promoting reforestation in partnership with their
families, local community groups and customers.

Launched on Earth Day in 2003, Ten Million Trees grew from the
successful One Million Trees program, which began in 1998 with the goal
of Alcoa planting a million trees within 10 years. Employees and their
families at more than 140 Alcoa locations in 20 countries raced to that
goal in half the time expected.
