The Vertical Policy Harmonization Indices (VPHI)
Listed in SWISSUbase
This dataset includes all the data compiled for the construction of two distinct Vertical Policy Harmonization Indices, the Target Index and Policy Effort Index, which measure the gap between countries’ NDCs and national policies concerning political commitment to mitigate climate change.
Description
The indices are constructed along three indicators that reflect key dimensions of climate policymaking: compliance emissions which refer to the level of emission countries aim to achieve under their GHG emission reduction targets, scope which captures the sectors covered by those targets, and policy mix which relates to the portfolio of policy instruments introduced to reduce emissions.
These indicators rely on datapoints that were drawn from various sources or generated during the content-based coding of countries' NDCs and national policy documents. The compliance emissions and scope indicators draw on target- and emissions-related data (e.g., level of commitment, target type, base year emissions, sector coverage) and data for the policy mix indicator was extracted from countries' national policy documents and includes information (e.g., information type, implementation procedures, status) relating to their policy instruments for mitigating climate change.

In addition to the data used to construct these indicators and indices, the Vertical Policy Harmonization Indices Dataset includes policy-level information (e.g., application period, status, type, integration). Sources and detailed descriptions of the dataset are included under the respective files. This dataset was compiled and generated during the course of the SNIS project "What international negotiators promise and domestic policymakers adopt: Policy and politics in the multi-level climate change regime".
