1. Carbon footprint: the total amount of carbon dioxide released into the atmosphere as a result of the activities of an individual, event, organisation, community or products which are used in daily life

2. Carbon footprint of a product: the negative impacts on environmental sustainability caused by the product throughout its life cycle

3. Carbon handprint of a product: the positive impacts on environmental sustainability caused by the product throughout its life cycle

4. Carbon handprint measures

• Use of materials with low carbon footprint in product manufacturing
• Extending the life cycle and increasing the efficiency of a product
• Use of energy that emits fewer greenhouse gases and highly-efficient energy converters
• Efficient management of waste towards environmental sustainability
• Elimination of greenhouse gases and storage of carbon dioxide in carbon sinks
