The impact of climate change on the planet is tremendous and requires concrete and immediate action. The rise in the Earth's temperature, caused in large part by the emission of greenhouse gases, has consequences that are well identified, such as rising sea levels, loss of biodiversity, extreme weather events and the effects on agriculture and human health.

What commitments have countries made?
The Paris Agreement was signed by 194 countries during the United Nations Climate Conference in 2015. The member states pledged to limit global warming to 2 degrees Celsius and to try to meet the initial target of keeping it to 1.5 degrees Celsius. The European Union, through the European Green Deal (signed in 2019), has committed to making Europe carbon neutral by 2050.

According to the Food and Agriculture Organization of the United Nations (FAO), around 14% of the food produced each year is wasted between production and sale. The figure rises to 17% at the sale and consumption stage. Waste, whether it's food, materials, electronics or anything else, has direct and serious consequences for the environment, the economy and human health.
The Circular Economy model (see interactive question) makes it possible to fight waste effectively.

What is the Circular Economy?
The circular economy is the model of consumer production that involves sharing, renting, reusing, repairing, renewing and recycling materials and products, allowing their life cycle to be extended.

The need to feed a growing population, combined with the finiteness of natural resources, poses social, environmental and economic challenges, requiring significant changes to meet the needs of present and future generations. The need to move towards a sustainable development model requires a more responsible pattern of production and consumption.



Weight of food consumption in Portugal's ecological footprint

A high poverty rate, low wages and wage inequality are a reality in Portuguese society. This is also true of other countries, particularly some major producers of food raw materials. Building an equitable society that promotes dignified lives for all citizens must be everyone's concern, particularly companies, which through their remuneration policies can play an active role in solving this challenge.
