The Paris Agreement is an international treaty that was adopted by almost all countries in the world in 2015 at the United Nations Climate Change Conference (COP21) in Paris. Its primary aim is to combat climate change by limiting global warming to well below 2 degrees Celsius above pre-industrial levels, and pursuing efforts to limit the increase to 1.5 degrees Celsius.

Under the Paris Agreement, countries are required to submit voluntary emissions reduction targets, known as Nationally Determined Contributions (NDCs), every five years. These targets are intended to reflect each country`s highest possible ambition in reducing greenhouse gas emissions, and the progress towards achieving these targets will be tracked and reported by the UN.

The Paris Agreement also includes provisions for developed countries to provide financial assistance to developing countries to help them adapt to the impacts of climate change and transition to low-carbon economies. This assistance is intended to support developing countries in reducing their emissions while promoting sustainable development and poverty eradication.

One of the most significant aspects of the Paris Agreement is its global scope. Almost all countries in the world have ratified the agreement, demonstrating a shared commitment to addressing the urgent threat of climate change. This collective effort is crucial in order to limit the devastating effects of climate change, including rising sea levels, more frequent extreme weather events, and food and water shortages.

Overall, the Paris Agreement is a crucial global effort to tackle climate change, and it represents a significant step forward in the fight against this critical issue. However, it is important to note that much more needs to be done in order to achieve the ambitious targets set out in the agreement. This includes continued efforts to reduce emissions, increase investment in renewable energy and other low-carbon technologies, and promote sustainable development practices.
