San Diego, CA, December 23, 2025
A study from UCSD reveals that using both incentives and penalties, known as the ‘carrots and sticks’ approach, could reduce energy-related carbon emissions by 80% by 2050. The importance of consistent policies in driving these changes was strongly emphasized, showing that a balance of support and deterrence is crucial for effective decarbonization efforts. Global experiments and various national policies are examined to highlight the significance of both strategies in driving emissions reductions.

Study Shows ‘Carrots and Sticks’ Approach Could Cut Carbon Emissions by 80%
A recent study by researchers from the University of California, San Diego (UCSD) and other institutions indicates that a combination of incentives and penalties—referred to as “carrots and sticks”—could lead to an 80% reduction in energy-related carbon emissions by 2050. The study emphasizes the importance of consistent and predictable policies to effectively drive decarbonization efforts.
Study Findings
The research utilized a model to explore how different climate policies, including incentives (carrots) and penalties (sticks), impact emissions over time. Key findings include:
- Combined Approach: Implementing both incentives and penalties is more effective in reducing emissions compared to using either strategy alone.
- Policy Consistency: Consistent and predictable policies are crucial, as policy unpredictability can lead to delays in investment and hinder progress toward decarbonization goals.
- Global Experiment: The study highlights a global experiment in real time, with different countries adopting varying approaches to decarbonization, including the use of incentives and penalties.
Implications for Policy and Implementation
The study underscores the need for a balanced policy approach that combines incentives to encourage the adoption of green technologies with penalties to discourage high-emission practices. It also points out that inconsistent policies can lead to delays in investment, making it politically and economically harder to act later. The researchers advocate for a more proactive and consistent policy framework to achieve significant emissions reductions by mid-century.
Background Context
Achieving an 80% reduction in energy-related carbon emissions by 2050 aligns with global climate targets aimed at mitigating the impacts of climate change. Previous studies have also emphasized the importance of both incentives and penalties in driving emissions reductions. For instance, a report by the International Energy Agency (IEA) suggests that a combination of supportive policies and regulations is necessary to accelerate the transition to a low-carbon economy. Additionally, the European Union has implemented various “carrots and sticks” policies to promote renewable energy adoption and energy efficiency improvements.
Conclusion
The UCSD study provides valuable insights into the effectiveness of combined incentives and penalties in achieving substantial emissions reductions. It calls for policymakers to adopt consistent and predictable strategies to foster a sustainable and low-carbon future. By advocating for policies that combine the best of both carrots and sticks, San Diego and the wider community can lead the charge toward a greener economy, benefiting local businesses and the environment alike.
FAQ
- What is the ‘carrots and sticks’ approach?
