The Role of Regulatory Frameworks in Reducing Carbon Emissions: Insights from the Energy and Lighting Sectors — •Jörg Cosfeld — University of Applied Sciences Düsseldorf, Düsseldorf 40476, Germany

Sustainability requires the cessation of carbon dioxide and other greenhouse gas emissions to prevent irreversible and abrupt climate tipping points. This work provides a concise summary of carbon dioxide emissions from the US energy sector and evaluates its greenhouse gas (GHG) abatement potential by 2030. Feasible solutions in a mid-range scenario suggest a reduction of up to 3.0 gigatons of CO2-equivalent emissions at costs below 50 USD per ton. Key opportunities lie in energy efficiency improvements and advanced technologies, particularly in buildings, appliances, and power generation, offering both environmental and economic benefits.

The study emphasizes that regulatory frameworks are often better suited for industry sectors than for individual actions, especially in developing countries, where affordability remains a significant barrier. For instance, 5 USD may buy a single LED light but also 10 incandescent bulbs, highlighting the economic trade-offs for low-income households. Comparing US and European regulations, the study discusses the EU ban on incandescent bulbs and Germany's Building Energy Act (GEG), which faced significant public opposition.

In conclusion, regulatory frameworks can effectively support climate change mitigation but require careful design to ensure both practicality and applicability, particularly in economically diverse regions.
