Three North American Pepsi-Cola bottlers have laid out plans to become greener companies.

The Pepsi Bottling Group, PepsiAmericas and Pepsi Bottling Ventures have all purchased renewable energy certificates (RECs) to match the electricity used by their operations to help drive the development of green power in the US.

The companies said yesterday (30 July) that they plan on purchasing nearly 629m kilowatt hours of green power annually through RECs, the equivalent to the amount of electricity needed to power nearly 39,000 households per year, according to estimates from the Environmental Protection Agency (EPA).

The Pepsi Bottling Group will purchase RECs to match almost 458m kWh of power, while PepsiAmericas will purchase RECs to match over 157m kWh of power and Pepsi Bottling Ventures plan to purchase RECs to match nearly 15m kWh of power.

Pepsi-Cola North America president and CEO Dawn Hudson said: "The purchases made by these three bottlers represent a broader effort by our entire system to work together and continue what PepsiCo started in April with its record purchase. This represents a collective approach to protecting the environment and becoming more sustainable in the long-term - something our consumers, customers, employees and investors can feel good about."

EPA's deputy administrator Marcus Peacock added: "America is shifting to a 'green culture,' with more and more businesses understanding that environmental responsibility is everyone's responsibility. EPA commends the Pepsi bottlers for making a long-term commitment to protecting the environment."

All three Pepsi bottlers are purchasing RECs from green power marketer Sterling Planet, which also supplied RECs for PepsiCo's green power purchase of more than 1.1bn kWh earlier this year. The bottlers' purchase of certificates will support the development of a combination of wind, small-scale hydro electric, biomass, landfill gas, biogas and geothermal resources.
