Climate change is one of the most well-known global issues, that could eventually lead to the loss of livable environment.
A total of 196 countries signed the Paris Agreement in 2015 to coordinate their efforts to address climate change, setting a common goal for the acceding parties to hold the increase in the global average temperature to below 2°C and pursue efforts to limit it to 1.5°C above preindustrial levels.
Anthropogenic impact on the environment in the form of greenhouse gas (GHG) emissions is a key contributor to global warming, as GHGs accumulate in the atmosphere, trap thermal radiation from the Earth's surface and thereby prevent the planet from cooling.
This is why climate change mitigation measures focus on reducing greenhouse gas emissions, and since cities account for between 67% and 72% of the main GHG emissions globally (according to the IPCC 2022 report), city governments have a special role to play in efforts to limit the rise in the global average temperature.
