The Paris Agreement is an international treaty aimed at mitigating the impact of climate change by reducing greenhouse gas (GHG) emissions. The Agreement was adopted in 2015, and since then, countries around the world have been working to meet their GHG reduction targets.

The Paris Agreement`s goal is to limit the global temperature increase to well below 2 degrees Celsius above pre-industrial levels, and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius. To achieve this goal, countries have committed to reducing their GHG emissions.

The GHG reduction targets set by countries vary depending on their level of development and current emissions. Developed countries, such as the United States and European Union member states, have committed to reducing their GHG emissions by at least 40% by 2030 compared to 1990 levels. Developing countries, including China and India, have committed to reducing their emissions intensity, which means reducing the amount of emissions per unit of GDP.

Countries must regularly report on their progress towards meeting their GHG reduction targets. This reporting is important because it allows for transparency and accountability. It also helps countries identify areas where they can improve and develop new strategies to reduce their emissions.

The Paris Agreement also provides a framework for countries to work together on climate change action. This includes financial and technological support for developing countries, as well as collaborative efforts to reduce emissions from international shipping and aviation.

While the Paris Agreement is a significant step towards addressing climate change, it is not perfect. Some critics argue that the GHG reduction targets are not ambitious enough to limit the temperature increase to 1.5 degrees Celsius. Others argue that the Agreement lacks enforcement mechanisms and that countries can withdraw from the treaty if they choose to do so.

Despite these criticisms, the Paris Agreement remains a critical tool for addressing climate change. As countries work towards meeting their GHG reduction targets, we must continue to push for more ambitious action to mitigate the impact of climate change for future generations.
