Global baseline for climate policy outcomes

❓❓❓WHICH CLIMATE POLICIES WORK   💡New insights on this crucial question in our new paper 'Climate policies that achieved major emission reductions: Global evidence from two decades', published last week in Science.   This is probably the most important study that I have contributed to. Screening more than 1500 climate policies implemented between 1998 and 2022 across 41 countries from 6 continents, we identify those policy combinations that were successful in achieving substantial emission reductions (see picture below). This offers crucial guidance for countries to design climate policies and fight climate change.   Key messages: ✅Mixes>standalone: Climate policies tend to work best if they're part of a policy mix rather than implemented alone. ✅There is no one-size fits all approach: Successful policy mixes vary across sectors and between developed and developing countries.   This study was possible thanks to our #OECD Climate Actions and Policies Measurement Framework (CAPMF). This is exactly the kind of empirical research, for which we have developed the CAPMF. I'm very hopeful that this study will pave the way for further research that supports countries to develop best practices.   Links Study: https://lnkd.in/emNSyUmw Climate policy explorer: https://lnkd.in/e4YyxwKa CAPMF dataset: https://oe.cd/dx/capmf   Many thanks to my co-authors Annika Stechemesser, Nicolas Koch, Ebba Mark, Elina Dilger, Patrick N.

Only a fraction of climate policy interventions produces significant results, according to a big study published in 'Science' yesterday. The study assessed 1500 policies (e.g., changes in subsidies and taxes) implemented between 1998 and 2022 across 41 countries. Only 63 policies showed large effects on reduced emissions (so-called 'breaks'). ❗We have a 'climate ambition gap' (policies do not aim high enough), but we also have a significant 'climate outcome gap' (those policies that are implemented often do not produce significant enough results). ❗ Key take aways: 1️⃣ Taxation and price incentives are by far the most effective policy instruments to achieve emission breaks. "It [taxation] stands out as the only policy instrument that achieves near equal or larger effect size as a stand-alone policy across all sectors." 2️⃣ Successful emissions reductions usually rely on mixes of different interventions (with tax and price incentives being part of the mix). Market-based instruments and regulations (e.g., product bans) need to be aligned and work together (e.g., banning fossil cars, increasing the price of gasoline, and subsidising e-mobility). 3️⃣ Most successful policy interventions occur in the building sector, followed by transport , industry, and electricity. Success rates vary strongly by sector and policymakers should therefore contextualise interventions. Successful climate policies need the right mix of instruments and have to include taxation and pricing measures to show significant outcomes!

Climate Policies: A Global Analysis of Emission Reduction Successes A new study published in Science, "Climate policies that achieved major emission reductions: Global evidence from two decades", provides a groundbreaking assessment of climate policies and their effectiveness in curbing emissions. The study, conducted by researchers at the Potsdam Institute for Climate Impact Research (PIK) and Mercator Research Institute on Global Commons and Climate Change (MCC), analyzed over 1500 climate policy interventions across 41 countries from 1998 to 2022. 📢 Key Findings: 1️⃣ Policy Mixes Drive Success: The study found that large emission reductions were primarily achieved through well-designed policy mixes rather than individual policy instruments. 2️⃣ Sector-Specific Best Practices: Effective policy mixes varied across sectors, suggesting the need for tailored approaches based on the specific characteristics of each sector. For example, pricing policies proved particularly successful in the industry sector, while regulations and subsidies were more effective in the buildings and transport sectors. 3️⃣ Economic Development Plays a Role: The study found that effective policies differed between developed and developing economies. Notably, carbon pricing was less successful in driving emission reductions in developing economies, likely due to market limitations and other factors. 4️⃣ Taxation Stands Out: Across all sectors, taxation (carbon and fuel taxes) consistently emerged as the most effective policy instrument in achieving large emission reductions, both individually and as part of a policy mix. 5️⃣ Need for Increased Effort: While the study identified 63 successful interventions with significant emission reductions, it also revealed that even greater policy efforts are needed to close the global emissions gap. 📢 Key Insights: 1️⃣ Importance of Policy Mixes: This research provides robust empirical evidence for the effectiveness of policy mixes in driving significant emission reductions. 2️⃣ Sector-Specific Approaches: Policymakers need to move away from a "one-size-fits-all" approach and instead design policies tailored to the unique characteristics of each sector. 3️⃣ Understanding Context is Crucial: The effectiveness of specific policies can vary depending on the economic development context, highlighting the need for tailored approaches for developing economies. 4️⃣ The Power of Pricing: Taxation emerges as a key driver of emission reductions, underscoring the importance of carbon pricing mechanisms in incentivizing decarbonization. This study provides valuable insights for policymakers and stakeholders seeking to design and implement effective climate policies. The findings emphasize the importance of comprehensive policy mixes, sector-specific strategies. #ClimatePolicy #EmissionReductions #PolicyMixes #CarbonPricing #Decarbonization #EnergyTransition #IPCC #ParisAgreement #Sustainability

A new study published in Science reveals that while 1,500 climate policies aimed at reducing greenhouse gas emissions have been implemented globally over the past two decades, only 63 policies, or about 4%, have substantially reduced emissions. Most successful emissions reductions were achieved through price instruments like carbon pricing, energy taxes, and subsidy reforms, often combined across multiple national policies rather than relying on a single approach. Researchers found if every country were to adopt best practices, up to 41% of the emissions gap could be closed by 2030. However, the study is not without its limitations, with researchers noting the analysis' exclusion of agriculture and land use policy due to insufficient data as well as the lack of representation of many countries Global South, especially those in Africa and Latin America.

96% of climate policies have failed, according to a study published in Science Magazine. 🌱 The results of the global dataset were sobering. Across 4 sectors, 41 countries, two decades and 1,500 policies, only 63 successful policy interventions with large effects were identified, which reduced total emissions between 0.6 and 1.8 Gt CO2. This is in the range of what the voluntary carbon market has separately reduced emissions. 🐠 It highlights how relatively effective the #VCM has been compared to government policy making. 🦜 Developed and developing countries have different #climate policy needs: In developed countries, #carbon pricing stands out as an effective policy, whereas in developing countries, regulation is the most powerful policy. 🌿 The Paris emissions gap can be closed: Focusing on the 63 cases of effective climate policies would close the current emissions gap to meet the #Paris Targets by 26% -41%, a significant contribution. 🔥 UN Environment Programme estimates that there remains a median emissions gap of 23 billion tonnes of CO2 equivalent by 2030. Summary at: https://lnkd.in/d6ZQx3qW

A comprehensive analysis of climate policies implemented across 41 countries from 1998 to 2022 has identified 63 successful interventions that reduced emissions by 0.6 to 1.8 billion metric tonnes of CO2. The study highlights the effectiveness of well-designed policy mixes, particularly those incorporating price-based instruments, in addressing the emissions gap. Findings indicate that successful policy approaches vary by sector and region, with pricing mechanisms proving effective in developed economies and regulatory measures showing promise in developing economies. The research underscores the need for tailored, diverse policy instruments and increased efforts to meet global climate goals, as current successful practices would need to be scaled up more than four times to close the emissions gap. #climateaction #parisagreement #emissionreduction #sustainablefuture #climatepolicy #globalimpact #environmentalstrategy #netzero #climatechange #policyinnovation

Scientists from PIK have delivered a groundbreaking evaluation of climate policy measures covering the last two decades. The study unveils the first comprehensive global evaluation of 1,500 climate policy measures from 41 countries across six continents, providing a detailed impact analysis of the wide range of climate policy measures implemented. The findings reveal a sobering reality: many policy measures have failed to achieve the necessary scale of emission reductions, with only 63 instances of successful climate policies, leading to average emission reductions of 19%, identified. Perhaps unsurprisingly, the key characteristic of these successful cases appears to be the inclusion of tax and price incentives in well-designed policy mixes. An accompanying interactive website, the “Climate Policy Explorer,” offers a comprehensive overview of the results, analysis and methods, and is available here: https://lnkd.in/efTeQBPb.

New global study reveals which climate policies actually work 📊🌍 On Thursday, researchers released a new paper in the journal Science Magazine that analyzed 1500+ climate policies across 41 countries over two decades to identify what truly reduces emissions. Key findings: • 63 policy interventions led to major emission reductions, totaling 0.6-1.8 Gt CO2 • Policy mixes often outperform single policies • Effective mixes vary by sector and country development level • Pricing policies (carbon taxes, ETS) are uniquely effective alone and in mixes • Transport sector shows most potential for policy synergies • Developing economies see more success with regulation & subsidies vs pricing The big takeaway: Even replicating these most successful policies globally would only close 26-41% of the emissions gap. We need 1.5-4x more ambitious efforts to meet Paris goals. Data-driven policy design is crucial.
