It is clear that we still have a lot of work to do with regard to our shared understanding of what constitutes strong, robust, effective and efficient global environmental governance. We need to better integrate regional and transnational initiatives with domestic policy strategies to tackle environmental problems. This means creating the conditions for a model of governing the environment that is flexible and cuts across different levels, from the local to the global. It is also clear that frameworks based on ideas of global public goods and global commons are very useful. However, at the same time they are daunting, since collective action on any scale is clearly an enormous challenge. Trying to find mechanisms, models and strategies to ensure cooperation across different levels of government, across a broad variety of issue areas and across a range of political and policy actors is a problematic and difficult process, as experience has shown. Today, the world’s states have been able to find common ground in relation to certain goals for environmental protection, including the flagpole issues of global warming and climate change. The hope is that this trend continues so we can continue to live healthily and happily on Planet Earth.
