Green Environment: Basic Factors

Greener Environment Sustainability

Renewable

No burden on environment

Utilizes natural resources

in a sustainable manner

In sync with the natural cycle

Carbon footprint reduction

Unending Production cycle (lifecycle)

Balances Climate

Cleanses & scavenges environ.

pollutants

Greener Environment

Preserves the ecology
