An environmental agreement, also known as an environmental treaty or convention, is a legally-binding agreement between multiple countries or parties that aims to protect and preserve the environment. Environmental agreements are typically created to address specific environmental issues that affect multiple countries or regions, such as air pollution, climate change, and biodiversity loss.

The goal of environmental agreements is to promote international cooperation and collaborative action to address environmental issues that cannot be solved by individual countries or regions alone. These agreements can take various forms, such as a framework convention, a protocol, or a memorandum of understanding.

One of the most significant environmental agreements is the Paris Agreement, which was adopted in 2015 by the United Nations Framework Convention on Climate Change. The Paris Agreement aims to limit global warming to below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius. It sets out a framework for countries to work together to reduce greenhouse gas emissions and adapt to the impacts of climate change.

Another important environmental agreement is the Convention on Biological Diversity, which was adopted in 1992. The Convention aims to conserve and sustainably use biodiversity, as well as to ensure equitable sharing of the benefits that arise from the utilization of genetic resources. The Convention has been ratified by almost all countries in the world, making it one of the most widely accepted international treaties.

While environmental agreements are an essential tool for addressing global environmental challenges, they can also encounter challenges. For example, some countries may be reluctant to sign on to agreements that require them to make significant changes to their economies or way of life. And even when agreements are signed, there may be challenges in implementation and enforcement.

Despite these challenges, environmental agreements remain a crucial tool for addressing global environmental issues. By working together, countries can achieve greater progress in protecting and preserving our planet for future generations.
