CICLO DE AMBICIÓN DEL ACUERDO DE PARÍS

The document describes the Paris Agreement's 'ambition cycle' as a four-stage iterative process: formulation of long-term strategies (LTS) and Nationally Determined Contributions (NDCs), implementation, monitoring via Biennial Transparency Reports (BTRs), and collective evaluation through the Global Stocktake (GST). It emphasizes the need for alignment between short-term NDCs and long-term net-zero goals, while warning against over-reliance on carbon markets and carbon capture technologies. The guide provides a national implementation roadmap and case studies from Costa Rica, the United Kingdom, Colombia, and Panama to illustrate best practices in climate governance and transparency.

• The 'ambition cycle' is an iterative process designed to ensure countries progressively design, implement, monitor, evaluate, and improve climate commitments to meet the long-term goals of Article 2 of the Paris Agreement.
• The cycle consists of four main stages: 1) Formulation of Long-Term Strategies (LTS) and Nationally Determined Contributions (NDCs); 2) Implementation; 3) Monitoring and tracking via Biennial Transparency Reports (BTRs), which were first due in December 2024; and 4) The Global Stocktake (GST), a collective evaluation occurring every five years.
• Long-Term Strategies (LTS) should provide a roadmap to net-zero emissions by the second half of the century, utilizing 'backcasting' to set intermediate milestones, such as global targets to reduce emissions by at least 43% by 2030 and 60% by 2035 relative to 2019 levels.
• The document warns that over-reliance on Carbon Capture and Storage (CCS), Carbon Capture and Utilization (CCU), and Carbon Dioxide Removal (CDR) technologies may lead countries to postpone deep emission reductions during the current critical decade.
• The first Global Stocktake (GST) established specific 2030 mitigation targets, including tripling global renewable energy capacity, doubling energy efficiency improvements, and phasing out inefficient fossil fuel subsidies.
• Effective national implementation requires a governance framework that includes a coordinating entity, multi-stakeholder engagement (including indigenous peoples and civil society), and scientific advisory committees to ensure goals align with the 1.5C threshold.
• Case studies highlight specific national successes: Costa Rica's 99% renewable electricity in 2021; the UK's Climate Change Act providing legally binding carbon budgets; Colombia's 'Ms clima' system for tracking 237 commitments; and Panama being the first Latin American country to publish its first BTR.
