The Paris Agreement, also known as the Paris Climate Accord, was a historic international agreement signed in 2015 by 196 countries to combat climate change. The aim of the agreement was to keep global warming below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C.

The Paris Agreement is a legally binding treaty that seeks to accelerate and intensify the actions and investments needed for a sustainable low carbon future. It replaces the previous Kyoto Protocol, which expired in 2020.

The agreement sets out a framework for countries to submit nationally determined contributions (NDCs) every five years, outlining their plans to reduce greenhouse gas emissions. The NDCs are not legally binding but are meant to be ambitious and transparent, with a goal to strengthen the global response to the threat of climate change.

The Paris Agreement also established a global goal to finance efforts to address climate change. Developed countries agreed to provide financial support to developing countries to help them transition to low-carbon economies and adapt to the impacts of climate change.

The agreement also recognizes the importance of preserving and enhancing carbon sinks, such as forests and oceans, which can absorb carbon dioxide from the atmosphere. Parties agreed to work towards conserving and enhancing these natural systems.

The Paris Agreement has been widely hailed as a significant achievement in the fight against climate change. However, it is not without its critics. Some argue that the targets set by the agreement are not ambitious enough to limit the worst impacts of climate change. Others have criticized the lack of enforcement mechanisms in the agreement.

Despite these criticisms, the Paris Agreement remains a landmark achievement in the global effort to address climate change. With renewed commitments from countries around the world, it has the potential to make a significant impact in reducing greenhouse gas emissions and building a sustainable future for all.
