“…The CPD comprises data on national climate change mitigation policy and is collected by the NewClimate Institute, supported by PBL Netherlands Environmental Assessment Agency and Wageningen University and Research (NewClimate Institute, 2022). The database was originally compiled to track policy adoption and detect gaps in climate policy (Nascimento et al, 2022). Several authors have used it to analyze patterns of climate policy adoption (Iacobuta et al, 2018) and the impact of mitigation policies on GHG emissions (Fekete et al, 2021;Giarola et al, 2021;Roelfsema et al, 2018Roelfsema et al, , 2020.…”

National policy ambition plays a central role in climate change governance under the Paris Agreement and is now a focus of rapidly emerging literature. In this contribution, we argue that policy ambition can be captured by the level of national policy activity, which in accordance with the existing literature should be referred to as “policy density.” In this study, we measure climate policy density by drawing on three publicly available databases. 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. For the first time, we compare the patterns of policy density within each database (2000–2019) and reveal that while they are different, they are nonetheless potentially complementary. 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.

“…We use data on climate policies from the website climatepolicydatabase.org, which provides to our knowledge the most comprehensive international dataset on climate policies. The dataset has been gradually composed over the recent years (Nascimento et al, 2021) and been analysed in a number of academic publications (den Elzen et al, 2019;Roelfsema et al, 2020;Fekete et al, 2021;Yao and Zhao, 2022). The dataset is based on other international datasets, reports, and country specific documents, and incorporates a variety of other popular datasets on climate (or in some cases more broadly environmental) policies such as the Climate Change Laws of the World (Eskander and Fankhauser, 2020) and OCED policy instruments database 2 .…”

Carbon pricing is considered the most efficient policy to reduce greenhouse gas emissions but it has also been conjectured that other policies need to be implemented first to remove certain economic and political barriers to stringent climate policy. Here, we examine empirical evidence on the the sequence of policy adoption and climate policy portfolios of G20 economies and other major emitters that eventually implemented a national carbon price. We find that all countries adopted carbon pricing late in their instrument sequence after the adoption of (almost) all other instrument types. Furthermore, we find that countries that adopted carbon pricing in a given year had significantly larger climate policy portfolios than those that did not. In the last part of the paper, we examine heterogeneity among countries that eventually adopted a carbon price. We find large variation in the size of policy portfolios of adopters of carbon pricing, with more recent adopters appearing to have introduced carbon pricing with smaller portfolios. Furthermore, countries that adopted carbon pricing with larger policy portfolios tended to implement a higher carbon price. Overall, our results thus suggest that policy sequencing played an important role in climate policy, specifically the adoption of carbon pricing, over the last 20 years.

“…2), the literature shows an increase in the uptake of climate-relevant policies around the world (e.g. Averchenkova et al, 2017) and in major emitting countries (Nascimiento et al, 2021) over the years. However, current measures are insufficient to implement the NDC targets and global emissions could be further reduced through a wider adoption of good practice measures (Roelfsema et al, 2018).…”

“…We assume that types of climate measures that predominantly offer co-benefits, would be favoured by more countries and therefore assess a potential correlation between the overall number of positively affected SDG targets as weighted by the score given in the scoring framework, and the number of G20 member states that adopted these measures. The data on climate-change mitigation policies and measures in these countries was extracted from the Climate Policy Database 42 , based on the 2020 update by (Nascimiento et al, 2021).…”

Enablers of ambitious climate action : Challenges and opportunities to combine climate change and sustainable development

Global climate change governance has changed substantially in the last decade, with a shift in focus from negotiating globally-agreed GHG reduction targets to nationally determined contributions, as enshrined in the Paris Agreement. This paper analyses trends in adoption of national climate legislation and strategies, GHG targets, and renewable and energy efficiency targets in almost all UNFCCC Parties, focusing on the period between 2007 and 2017. The uniqueness and added value of this paper resides in its broad sweep of countries, the more than decade-long coverage, and the use of objective metrics rather than normative judgements. Key results of this paper show that national climate legislation and strategies witnessed a strong increase in the first half of the assessed decade (2007-2017), likely due to the political lead up to the Copenhagen Climate conference in 2009, but have somewhat stagnated in recent years, currently covering 69% of global GHG emissions (almost 50% of countries). In comparison, the coverage of GHG targets increased considerably in the run up to adoption of the 2015 Paris Agreement and 93% of global GHG emissions are currently covered by such targets. Renewable energy targets saw a steady spread, with 79% of the global GHG emissions covered in 2017 compared to 45% in 2007, with a steep increase in developing countries.
