Transition énergétique ?

À l’échelle mondiale, nous venons d’épuiser notre quota de ressources planétaires pour l’année 2025, alerte ce mercredi l’ONG Global footprint network, qui actualise chaque année la date de ce «dépassement». Cette fois, le couperet est tombé un jour plus tôt que l’an dernier, soit la date la plus précoce jamais annoncée par l’ONG.

Countries must move rapidly to slash CO2 emissions from homes, offices, shops and other buildings—a sector that accounts for a third of global greenhouse gas pollution, the United Nations said Monday. Carbon dioxide emissions from the building sector rose around 5% in the last decade when they should have fallen 28%, according to a new report by the United Nations Environment Program (UNEP).

To truly evaluate your impact on the environment, you have to go way beyond recycle bins and energy bills...

This report focuses on the 20 investors and 20 banks that are funding the methane generating activities of 15 of the leading meat and dairy companies worldwide. Collectively these financial institutions fund a methane footprint that could exceed 503 Mt CO2e – nearly as big as the CO2emissions of Saudi Arabia.

Researchers have been able to cut their carbon footprint by jetting off to fewer international conferences, but physicists working on large-scale experiments may also have to consider the significant environmental impact of the computer power they require. Michael Allen investigates

The Belgian Institute for Sustainable IT is a think and do tank founded in 2020, based on its French equivalent the INR. Our aim is to bring together Belgian companies, organizations and individuals, and help them succeed their digital transition while reducing the environmental and social footprint of their IT services and usages. Thanks to the support of our members and of public authorities, we promote digital technologies and services that are more sustainable, inclusive and ethical.

An ecological deficit occurs when the Ecological Footprint of a population exceeds the biocapacity of the area available to that population. A national ecological deficit means that the nation is importing biocapacity through trade, liquidating national ecological assets or emitting carbon dioxide waste into the atmosphere. An ecological reserve exists when the biocapacity of a region exceeds its population's Ecological Footprint.

Even “sustainable” technologies such as electric vehicles and wind turbines face unbreachable physical limits and exact grave environmental costs

New research suggests social transformations that prompt “degrowth” could cut humanity’s climate footprint in time to meet the Paris climate agreement target.
