Understanding the Risks Associated with Greenhouse Gas Emissions

Greenhouse gas (GHG) emissions represent a set of major risks for our planet and all living beings residing on it. By increasing the concentration of GHGs in the atmosphere, we disrupt the Earth's climate balance, leading to serious consequences. The primary risk is climate change, which causes dramatic environmental changes such as rising sea levels, extreme weather events, and disruption of ecosystems. These changes have repercussions on agriculture, water availability, and human health. Reducing GHG emissions and transitioning to a sustainable economy is essential to prevent these risks and protect our planet.

What is the difference between 'Collective' carbon footprint and 'Territory' carbon footprint?
The 'Territory' carbon footprint aims to estimate the total (communities, individuals, and businesses) greenhouse gas emissions in the territory of the concerned community. MyCityCO2 provides the community's footprint, without estimation, based on the municipality's administrative accounts and by measuring emissions related to buildings, infrastructures, services, etc., of the community.
How is the trajectory of the Low Carbon National Strategy (SNBC), France's roadmap to meet the Paris Agreement, calculated?
According to the Secten report which presents greenhouse gas emissions in France since 1990 (Citepa, 2023. Greenhouse gases and atmospheric pollutants. Emission balance in France from 1990 to 2022. Secten report ed. 2023.), emissions were 456.4 Mt CO2e in 2016 and the objective defined by the Paris Agreement of -50% by 2030 compared to 1990 leads us to 270 Mt CO2e for 2030. By extrapolation, since 2016, communities must follow a trajectory of reduction of 3.65% each year.


Paris Agreement

The Paris Agreement is an international agreement on climate change adopted in 2015 during COP21. It aims to limit global warming to less than 2 degrees Celsius compared to pre-industrial levels and to pursue efforts to limit the temperature rise to 1.5 degrees Celsius.
