What is Paris Agreement?

Paris Agreement

Quick Answer

The Paris Agreement is an international treaty aimed at combating climate change by limiting global warming to well below 2 degrees Celsius above pre-industrial levels. It encourages countries to set their own targets for reducing greenhouse gas emissions and to report on their progress regularly.

Overview

The Paris Agreement was adopted in 2015 by nearly every country in the world as a response to climate change. It establishes a framework for countries to work together to reduce greenhouse gas emissions and adapt to the impacts of climate change. Each country sets its own targets, known as Nationally Determined Contributions (NDCs), which they aim to achieve over time. The agreement operates on a system of transparency and accountability, where countries are required to regularly report their progress and update their targets every five years. This encourages nations to increase their ambitions over time and fosters a sense of collective responsibility. For example, many countries are investing in renewable energy sources like wind and solar power to meet their goals and reduce reliance on fossil fuels. The significance of the Paris Agreement lies in its global approach to climate change, emphasizing that it is a shared challenge that requires cooperation across borders. By bringing together countries with different economic situations and capacities, the agreement aims to ensure that all nations can contribute to the fight against climate change. This collaborative effort is essential for protecting ecosystems, human health, and the economy from the adverse effects of a warming planet.
