As a professional, I`ve researched the topic of the largest agreement in the world and have found the following information.
The largest agreement in the world is the Paris Agreement, also known as the Paris Climate Accord. This agreement was signed by 197 parties, including 195 United Nations Framework Convention on Climate Change (UNFCCC) member countries and the European Union, in December 2015.
The Paris Agreement aims to limit global warming to well below 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels while pursuing efforts to limit the increase to 1.5 degrees Celsius (2.7 degrees Fahrenheit). This is in line with scientific consensus on the need to limit global warming to avoid the most catastrophic impacts of climate change.
The Paris Agreement is a legally binding agreement, which means that countries are required to take action to meet their commitments. Each country sets its own targets, known as nationally determined contributions (NDCs), which are reviewed and updated every five years.
In addition to setting a temperature goal, the Paris Agreement also includes provisions for finance, technology transfer, and capacity building to support developing countries in their efforts to mitigate and adapt to climate change.
The Paris Agreement is widely regarded as a historic achievement in the fight against climate change. However, it has been criticized for not being ambitious enough to meet the goals of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) and for not including binding enforcement mechanisms.
Despite these criticisms, the Paris Agreement is a significant step forward in addressing the urgent need to reduce greenhouse gas emissions and mitigate the impacts of climate change. It represents the largest agreement in the world and a collective effort to save our planet for future generations.
