CICLO DE AMBICIÓN DEL ACUERDO DE PARÍS

This guide by Transforma explains the "ambition cycle" of the Paris Agreement, an iterative process designed to help countries progressively improve their climate commitments through formulation, implementation, monitoring, and evaluation. It details the key instruments involved—such as Nationally Determined Contributions (NDCs) and Long-Term Strategies (LTS)—and provides a roadmap for national implementation to align short-term actions with long-term goals like net-zero emissions by 2050.

• The Paris Agreement's ambition cycle is an iterative process consisting of four main stages: the formulation of long-term strategies and NDCs; the implementation of these commitments; continuous monitoring and reporting; and a collective evaluation known as the Global Stocktake (GST).
• Nationally Determined Contributions (NDCs) must be submitted every five years, cover all economic sectors, show progression from previous goals, and align with long-term strategies. The first round was in 2015, the second in 2020, and the third in 2025.
• Long-Term Strategies (LTS) serve as roadmaps for decarbonization, typically targeting a 2050 horizon to reach net-zero emissions. As of January 2025, only 75 countries, representing 74.8% of global greenhouse gas emissions, have submitted such strategies.
• Biennial Transparency Reports (BTRs) are mandatory instruments used to report progress every two years on mitigation goals, adaptation priorities, and greenhouse gas inventories. The first BTRs were due in December 2024.
• The Global Stocktake (GST) is a collective evaluation occurring every five years to assess global progress toward limiting temperature rise to 1.5°C. The first GST, adopted at COP 28 in late 2023, called for tripling global renewable energy capacity and doubling energy efficiency by 2030.
• The document warns against over-reliance on carbon markets and specific technologies like Carbon Capture and Storage (CCS), Carbon Capture and Utilization (CCU), and Carbon Dioxide Removal (CDR). It notes that these can be costly, may allow continued fossil fuel use, or risk compromising food security and biodiversity if scaled up improperly.
• Effective national implementation requires a governance framework with a coordinating entity, multi-stakeholder involvement (including indigenous peoples and civil society), and scientific advisory committees to ensure goals are aligned with the latest climate science.
