How does the Pepsi company help to protect the environment? What things are they doing to protect the environment?

I examined in detail the below referred website of Pepsi
describing achievements of Pepsi in the area of environment protection. This site speaks
of many award and recognition it has won for environmental protection. It also talks
about the signing various agreements and making announcement which show its intention to
do something for environment protection.

However, I think
it will be proper to point out that on going throughout the details the only concrete
achievement is using solar energy for some of the processes for some of the products in
a few specified plants. There is no concrete data on the extent of use of solar power
either in absolute terms as a percentage of total energy consumed by the
company.

Also there is mention of solar power for
advertising. Again without any supporting data.

Claims to
plant, in collaboration with National Arbo Day Foundation, also on closer examination
turns out to be announcement to distribute plants (50,000), seedling (50.000), and plant
trees (200,000). Information on actual progress is not
provided.

The company has listed purchase of renewable
energy certificates as one of its achievement in the are of environmental protection. I
do not understand the logic of such claims. Such certificates are generally purchased by
companies form other less polluting companies, to compensate for their inability to keep
environmental pollution within acceptable limits.

I think,
any claims to protection of environment should be limited to only those achievements
which are beyond the minimum acceptable requirements.
