In 2025, climate transparency achieved a significant milestone under the Paris Agreement. This year marked the end of the first Enhanced Transparency Framework (ETF) cycle, involving key submissions like the Biennial Transparency Reports (BTRs). These reports, supported by Technical Expert Reviews (TERs), laid the groundwork for clear and reliable climate data.
At the Global Transparency Forum, held in September in South Korea, countries emphasized the importance of transparency. They viewed it not just as a technical detail but as a crucial part of building trust and cooperation. This sentiment echoed at the COP30 High-Level Ministerial Dialogue, where leaders recognized transparency as the bedrock of effective global collaboration.
A landmark achievement in 2025 was the release of the first BTR Synthesis Report. It revealed that countries reporting progress are implementing substantial measures to meet their climate commitments. These actions include creating new systems to track emissions and mobilizing finance for clean energy projects. UN Climate Change Executive Secretary Simon Stiell noted that many nations now have comprehensive climate plans linked to long-term net-zero goals, integrating key values like gender equality and adaptation strategies.
Additionally, the Consultative Group of Experts (CGE) was granted ongoing support, solidifying its role in assisting developing nations with their reporting needs. This is essential for building capacities and fostering long-term transparency.
In 2025, around 120 BTRs were submitted, marking progress but also opening the door for continuous learning. The TER Annual Report identified successes and challenges, highlighting areas where additional support is necessary.
The launch of the Climate Data Hub, developed with Microsoft, EY, and NEDAMCO Africa, aimed to centralize climate information. This platform makes data more accessible, allowing users to easily find and utilize climate-related information.
Furthermore, the Non-State Actor Zone for Climate Action (NAZCA) is evolving. A new roadmap was introduced to enhance its role in collecting and sharing credible climate action data from various stakeholders. This development responds to the growing recognition of the roles that businesses and communities play in achieving climate goals.
Transparency is not only about government actions. The collaboration with the CDP led to meaningful reports on how corporate data can bolster national climate plans and attract finance. This is crucial for ensuring that efforts to combat climate change are comprehensive and effective.
As we move forward, the commitment to transparency remains vital. It not only strengthens accountability but also guides support for innovative climate solutions. The journey toward a more sustainable world depends on how well we track progress and share our findings with one another.
