Challeges of International Cooperation in Reducing Greenhouse Gas Emissions.

International cooperation to reduce greenhouse gas emissions faces challenges such as population growth, increased energy demand and anthropocentrism. Population growth and economic expansion has led to the increase in energy demand and greenhouse gas emission, which pollutes the atmosphere and causes surface temperature rise. It is important for people to replace fossil fuel with renewable energy, but renewable energy is not practical in technology in the transport sector, and renewable energy also has disadvantage. People need to transit to low-carbon lifestyle and establish environmental ethics, which are rules to regulate people’s behavior and to conserve the environment.
