The Paris Agreement has been a major topic of discussion in recent years, especially among politicians and environmentalists. The agreement was signed in 2015 by 195 countries, including the United States, with the aim of limiting global warming to below 2°C above pre-industrial levels. Each country also set their own targets for reducing greenhouse gas emissions.

However, in 2017, the United States announced its withdrawal from the Paris Agreement, citing the belief that the agreement would hurt the American economy and job market. The decision received widespread criticism from the international community and environmental groups.

Despite the withdrawal, the United States had originally intended to reduce its greenhouse gas emissions by 26-28% below 2005 levels by 2025. This target, set during the Obama administration, was seen as a key factor in the success of the Paris Agreement.

Many experts believe that the United States` withdrawal from the agreement has made it more challenging for other countries to meet their own targets. Additionally, the lack of support from the world`s largest economy and second-largest emitter of greenhouse gases has weakened global efforts to combat climate change.

In recent years, some states and cities within the United States have taken it upon themselves to continue pursuing emissions reductions. California, for example, has set its own target to reduce emissions to 40% below 1990 levels by 2030. New York has also set a goal of reducing emissions by 85% below 1990 levels by 2050.

The current administration has recently announced its intention to rejoin the Paris Agreement, which has been welcomed by many. However, it remains to be seen what the new targets will be and how they will be achieved.

In conclusion, the United States` original target for emissions reductions under the Paris Agreement was an important step in global efforts to combat climate change. While the withdrawal from the agreement was a setback, it is encouraging to see some states and cities continuing to push for emissions reductions. The decision to rejoin the Paris Agreement is a positive development, but it is important for the country to set ambitious and achievable targets for reducing greenhouse gas emissions.
