The Paris Agreement, which was adopted in December 2015 by 195 countries, aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels, and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius. The agreement also calls for countries to regularly report their progress towards meeting their targets.

The European Union (EU) played a significant role in the development of the Paris Agreement, and was one of the first signatories to the treaty. The EU has been a strong advocate for climate action, and has set ambitious targets for reducing greenhouse gas emissions.

In order for the Paris Agreement to come into force, it needed to be ratified by at least 55 countries, accounting for at least 55% of global greenhouse gas emissions. The EU, as a bloc, accounts for around 12% of global greenhouse gas emissions.

The EU ratified the Paris Agreement on October 5, 2016, just days after the required threshold was met. The swift ratification by the EU was widely seen as a critical step in bringing the Paris Agreement into force.

The ratification process involved all 28 EU member states individually ratifying the agreement. This was done through a process known as “provisional application”, which allowed the EU to formally ratify the treaty before all member states had completed their own ratification processes.

The EU`s ratification of the Paris Agreement was welcomed by climate activists and environmental groups around the world. It was seen as a strong signal of the EU`s commitment to climate action, and a clear indication that the bloc intends to take a leading role in the fight against global warming.

The EU has set ambitious targets for reducing greenhouse gas emissions, aiming to reduce them by at least 40% by 2030 compared with 1990 levels. The bloc has also established a number of measures aimed at promoting clean energy, including the EU Emissions Trading System and the Renewable Energy Directive.

The ratification of the Paris Agreement by the EU was an important moment in the fight against climate change. It demonstrated the EU`s leadership on this critical issue, and sent a clear message to the rest of the world that the bloc is committed to tackling global warming. As the world continues to grapple with the challenges of climate change, the EU`s ratification of the Paris Agreement provides hope that meaningful action can be taken to address this urgent issue.
