The greenhouse gas (GHG) agreement is an international agreement that was reached by the United Nations Framework Convention on Climate Change (UNFCCC) in 2015. The agreement 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 was signed by 195 countries and has been ratified by 189 of them. The countries that have ratified the agreement are committed to reducing their greenhouse gas emissions and to regularly reporting on their progress.

The GHG agreement has been hailed as a major step forward in the fight against climate change. It is the first time that the international community has come together to address the issue of greenhouse gas emissions in a meaningful way.

The agreement is designed to be flexible and to allow each country to determine its own greenhouse gas reduction targets. The countries are also encouraged to increase their targets over time as they are able to do so.

The GHG agreement is a significant achievement, but there are still challenges to be addressed. One of the biggest challenges is ensuring that countries actually meet their commitments. There is also the need to secure sufficient funding to support the implementation of the agreement.

In addition, there are concerns that the current targets may not be sufficient to prevent the worst effects of climate change. Some experts argue that more ambitious targets are needed if we are to avoid catastrophic consequences.

Despite these challenges, the greenhouse gas agreement represents a major step forward in the fight against climate change. It shows that the international community is committed to taking action to address this critical issue, and it provides a framework for countries to work together in pursuit of a common goal. By reducing greenhouse gas emissions, we can help to protect our planet and ensure a sustainable future for generations to come.
