Implications of Paris Agreement on the National Emissions Reduction Efforts

This report examines methods for setting national mitigation targets under the Paris Agreement to align with long-term temperature limits, specifically comparing cost-effectiveness and equity-based approaches. It discusses the role of international support in bridging the gap between these approaches, the spill-over effects of domestic climate policies, and the potential for the European Union to accelerate global climate efforts through its own neutrality goals and leadership.

• There are significant differences in emissions reduction levels when targets are determined using cost-effectiveness criteria versus equity-based criteria. This gap can be bridged if countries with high reduction goals based on fairness support those where least-cost criteria suggest higher reductions than equity considerations do, provided this support does not lead to carbon lock-in or merely finance the cheapest reductions in developing nations.
• Transitioning from fossil fuels to renewables and implementing energy efficiency measures can support multiple Sustainable Development Goals (SDGs), specifically SDG7 (affordable and clean energy), SDG1 and SDG10 (reduction of poverty and inequalities), and SDG11 (sustainable cities and communities).
• Domestic climate actions have spill-over effects on other countries, which can be amplified by active leadership and support from transfer agents. The report notes that rapid political changes in Brazil and the United States have exemplified these effects.
• The European Union has the potential to influence global emissions reductions beyond its own targets by pursuing climate neutrality by 2050 and an ambitious 2030 goal. However, at the time of writing, the proposed European Climate Law lacked a commitment to negative emissions after 2050 and an institutional setup, such as an Agency within the Commission, to oversee target achievement.
