L’utilisation des ressources naturelles

Pour faire tourner l’économie et répondre à tous nos besoins (se loger, se nourrir, se déplacer, s’équiper…), il faut utiliser des ressources naturelles. Il en existe de plusieurs types : l’eau, l’énergie (comme le pétrole ou le soleil), les plantes et animaux (biomasse), ou encore les minéraux (métalliques ou non). Ces ressources sont renouvelables ou non, mais toutes ont un impact sur l’environnement. C’est pourquoi il est important de faire preuve de sobriété, c’est-à-dire de les utiliser avec modération.

To run the economy and meet all our needs (housing, food, transportation, equipment…), we must use natural resources. There are several types: water, energy (such as oil or sunlight), plants and animals (biomass), and minerals (metallic or non-metallic). These resources are renewable or not, but all have an environmental impact. That is why it is important to practice sobriety, that is, to use them in moderation.

  • Rising consumption of raw materials, dwindling natural resources
    • In 2024, the "global overshoot day" fell on August 1st. This date is calculated by the Global Footprint Network. It marks the moment in the year when humanity has consumed all the resources that Earth can produce in one year. In 1970, this day fell on December 29th. Since then, it arrives progressively earlier. This shows that we are consuming increasingly more natural resources worldwide. According to UN Environment and the International Resources Panel, 30 billion tonnes of raw materials were extracted globally in 1970, compared to 107 billion tonnes in 2024. This figure has tripled in 50 years and could increase by 60% by 2060. This sharp rise is linked to population growth, but especially to rising per-capita consumption. Since 1970, the global population has doubled, and global wealth measured by gross domestic product (GDP) has quadrupled. With this very high consumption, it is increasingly difficult to achieve global objectives to protect the climate, reduce pollution and preserve biodiversity. There can also be negative effects on countries' economies and on population quality of life. The use of natural resources is thus responsible for: • more than 55% of greenhouse gas emissions, which accelerate climate warming; • and 40% of fine particles, which are very dangerous to health.
    • France consumes approximately 760 million tonnes of raw materials annually, or 11.2 tonnes per inhabitant. This 2022 figure is down 5% compared to 2021 and 2019. It is also lower than the European average of 14.2 tonnes per inhabitant. More than half of this consumption concerns construction materials, used for roads, buildings and other infrastructure. • Of these 760 million tonnes, 615 million tonnes come from France. These are mainly non-metallic minerals (sand, gravel), biomass (organic matter, such as wood or agricultural crops) and water. Although these resources are available in France, there are constraints. For example: • freshwater is becoming scarcer over the past twenty years; • opening new quarries or marine sand extraction zones is often contested; • biomass is renewable but regenerates at varying rates and its production also has environmental effects. • France also imports many natural resources. Half of these imports concern fossil fuels (oil, coal and natural gas), which emit large amounts of greenhouse gas. Moreover, these imports can represent risks in case of instability in supplier countries, or with rising prices and trade imbalances. • French economic consumption of raw materials in 2022
  • Energy resources: fossil fuels remain highly present and polluting
    • Energy is indispensable for all human activities. It can come from: • the sun, water, wind, biomass: these are renewable energies; • oil, natural gas, coal: these are fossil fuels; • fission of one or more radioactive elements: this is nuclear energy. In 2022, in France, 63% of energy consumption came from fossil resources such as oil, coal and gas).
    However, fossil resources are not infinite, are essentially imported and are the principal sources of two-thirds of global greenhouse gas emissions.
  • Water: an increasingly scarce resource
    • In France, freshwater is used for: • daily uses (drinking water); • economic activities (agriculture, industry, leisure, cooling power plants, etc.).
    To meet these needs, we have been using less freshwater over the past twenty years. In 2022, approximately 30 billion m³ of freshwater were withdrawn, compared to 32.9 billion m³ per year on average between 2008–2023. Freshwater remains abundant in France, but it is gradually diminishing. Between 1990–2001 and 2002–2022, it declined by 14%. The risk of water shortage, called "water stress", is especially significant in summer. During this season, 60% of water is consumed, while available water is at its lowest level. This situation can create local tensions and even conflicts over water use.
    Different activities consuming water in France
  • Animal and plant biomass: renewable resource with environmental consequences
    • Biomass consists of organic matter of biological origin: • crops (cereals, nuts, vegetables, fruits, fibres, etc.); • wood; • wild animals (from fishing or hunting).
    In France, biomass from agriculture and fishing represents 222 million tonnes, or 36% of extracted raw materials. It is the second most extracted natural resource in the country, after non-metallic minerals. It can be used for food, seeds, industrial uses or animal feed.
    However, even though biomass is renewable, it has environmental impacts. For example, intensive agriculture can cause soil erosion or water pollution from chemicals (pesticides) or excess nutrients (fertilizers, animal waste). It also requires other resources (mineral, fossil) and especially agricultural land or forests, which are limited.
    It is therefore essential to better manage the food and energy uses of biomass and limit its environmental impacts.
  • Mineral resources: different balance between metallic and non-metallic materials
    France primarily extracts non-metallic minerals such as sand and gravel. 392 million tonnes were extracted in 2022. This figure is down 10% compared to 1990. These materials are mainly used locally, but they are not renewable and their extraction, processing and transport have environmental consequences.
    In France, metallic ore extraction is very low: only 0.2 million tonnes per year. The country therefore imports nearly all its metal consumption, which was 17 million tonnes in 2022. With the energy transition, global demand for metals will increase further, for example for lithium, nickel, rare earths, etc. These metals are necessary for low-carbon technologies, that is, those that emit little or no CO₂: wind turbines, electric motors, batteries… New extraction, processing and especially recycling capacities for these metals must therefore be developed.
  • Priority: using fewer natural resources
    • A country's raw material consumption depends on: • its population; • living standards (measured by GDP); • type of economy (for example, services consume fewer materials than industry); • technological progress.
    The evolution of what is called "material productivity" allows measuring whether society is becoming more resource-efficient.
    • This means producing more with fewer raw materials. To address environmental, social and economic challenges, France has set the objective of increasing its material productivity by 30% between 2010 and 2030. In other words, we must produce more with fewer natural resources. This is the objective of the circular economy. • Understanding the circular economy and material productivity
