Countries vary widely in the extent to which they seek to decarbonize their economies and in the approaches they take. Much research points to how "political will" varies from country to country. The public, politicians and interest groups support climate action to varying degrees in different countries. That is why strong climate coalitions are emerging in some places, but not in others. While political will is an important driver of national climate ambitions, a country's ability to implement climate policy – especially its institutional and fiscal capacity – is also important.
