Green Star Energy’s vision is to be the gold standard in retail energy delivering stability, value and innovation in every customer, shareholder, employee and community relationship.
Having entered the domestic energy market at a point in time where energy suppliers were deemed to be public enemy number one, it’ safe to say as a new market entrant Green Star would have to experience some growing pains. But this clean slate has allowed Green Star to openly disclose their intentions within the market. The perfect opportunity to resonate with the Great British public, and they seem to have made the right noises.

With Green Star Energy committed to providing diverse and simple tariffs for all customers, they have a number of products to choose from. Within the first month of launching they were able to take up around 2,000 customers mainly acquiring customer moving away from the Big 6.

As you can appreciate, customers looking to leave the Big 6 suppliers are doing so seeking lower energy bills as well a level of customer service that justifies switching supplier to Green Star Energy. Green Star Energy is constantly striving to attain an exemplary level of customer satisfaction and therefore made a very early decision to ensure their billing and end-to-end customer information journey is perfect.

Green Star Energy have partnered with Carbon Footprint to help to support two worthwhile carbon reduction projects:

CIKEL Project – Amazon:
The CIKEL Project is located in Para State, Brazil, where 63% of the Amazon Rain forest has already been lost. By using sustainable logging practices certified by the Forest Stewardship Council, CIKEL will continue to avoid the deforestation of 27.4 thousand hectares of rain forest which would have been deforested had traditional logging practices been used.

Tree Planting in Schools – UK
Customers are helping plant native British broad-leaved trees across the UK. Most of the planting takes place in school locations and are only native British broad-leaved trees, ensuring they are in keeping with the local surroundings.

Planting trees not only offsets carbon emissions, but also protects wildlife habitats for many hundreds of years. All trees planted through Carbon Footprint are guaranteed to be in addition to any national quota, so you can be sure that trees would not have been planted without your support

Both projects are benchmarked against the Verified Carbon Standard (VCS). Carbon Credits earned are retired on a carbon registry to ensure no double counting. Carbon Footprint is also audited by the quality assurance standard (QAS) annually.
