New DeepDCarb Publications - July 2022
In Climate Policy Ambition: Exploring A Policy Density Perspective, we measure climate policy density from 2000-2019 by drawing on three publicly available databases: Climate Change Laws of the World, Climate Policy Database and the Policies and Measures Database. All three measurements show an upward trend in the adoption of climate policy. However, our empirical comparison also reveals differences between the measurements with regard to the degree of policy expansion and sectoral coverage, which are due to differences in the type of policies in the databases. Since the choice of the database and the resulting measurement of policy density ultimately depend on the questions posed by researchers, we conclude by discussing whether some questions are better answered by some measurements than others.
