Final answer:
The agreement signed by 181 countries in 2009 to sharply limit CO2 emissions was the Paris Agreement.
Explanation:
The agreement signed by 181 countries in 2009 to sharply limit CO2 emissions is the Paris Agreement. The Paris Agreement is an international treaty that 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. It was adopted by 196 countries in 2015 and entered into force in 2016.
The Paris Agreement sets out a framework for countries to take action to reduce greenhouse gas emissions, including CO2 emissions. Each participating country submits its own nationally determined contributions (NDCs) outlining its targets and actions to mitigate climate change. The agreement also includes provisions for financial support to developing countries and mechanisms for monitoring and reporting progress.
The Paris Agreement replaced the Kyoto Protocol, which was the previous international agreement on climate change. The Paris Agreement represents a global effort to address the urgent challenge of climate change and transition to a low-carbon and sustainable future.
