89% of the world's population is convinced that climate change is happening

Discover the second edition of the Ecological Transformation Barometer

Since 2022, Veolia has been publishing the Barometer of Ecological Transformation every two years, in partnership with the Elabe consulting and research firm.

Facing the climate and ecological wall, public debate has entered a new phase. Aware of environmental risks to their health and quality of life, populations around the world are demanding action. Existing solutions are widely accepted, but strategies to implement them struggle to structure on common grounds.

A barometer that affects 26 countries in the 5 continents

 The Barometer takes in 26 countries(1) on 5 continents covering a sample of more than half the human population. The countries were chosen for their demographic weight and their relevance: countries on the front line of the effects of climate change, but also countries that are pioneers in ecological policies.

The scope of this Barometer allows us to assess the global and local level of acceptability of existing ecological solutions and to discover the barriers and drivers that accompany the implementation of these solutions. An informative study that helps us to advance the debate and better understand how to achieve ecological transformation.

Ecological fear sweeps the planet

2/3of the world's inhabitants feel exposed and vulnerable to a risk related to climate change or pollution. 

64%feel exposed and vulnerable to a health risk (including 64% being in poorer health and 58% having mental health problems).

Decarbonize, depollute and regenerate resources

More than ⅔of the world's inhabitants are ready to pay a little more for:

  • energy produced locally from non-recyclable waste and biomass.

  •  water and for fruits and vegetables to finance solutions for treating water and soil pollution.

66%(+13% compared to 2022) are ready to drink potable water from the recycling of wastewater to reduce the risk of running out of water.
