By 2050, the world population is expected to reach 9.6 billion people, and that means that our current lifestyle could not be maintained since it exceeds our availability of natural resources.

Natural resources are those elements of nature that human beings use to cover their needs of well-being or development. For example: water, trees, minerals, fish, air, oil, etc.

Responsible consumption (RC) on natural resources aims to integrate social, environmental and ethical aspects into behavioural and purchasing decisions, guided by the following principles:

- Reduction: limitation of consumption by assessing the need for some purchases.

- Energy efficiency: looking for efficient, energy-saving products.

- Sustainability: ensuring the products have the minimum negative effect on the environment after the end of their useful life.

The objective of responsible consumption is advancing to a more circular economy, that keeps materials, products, and services in circulation for as long as possible, so reducing the use of materials and energy, as well as recapturing 'waste' as an input resource again.
