The importance of greenhouse gas inventories cannot be overstated: the process of producing inventories informs strategies that governments will use to meet emissions reduction targets. The Intergovernmental Panel on Climate Change (IPCC) leads an effort to develop and refine internationally agreed upon methodologies for calculating and reporting greenhouse gas emissions and removals. We argue that these guidelines are not equipped to handle the task of developing national greenhouse gas inventories for most countries. Inventory guidelines are vital to implementing climate action, and we highlight opportunities to improve their timeliness and accuracy. Such reforms should provide the means to better understand and advance the progress countries are making toward their Paris commitments. Now is the time to consider challenges posed by the current process to develop the guidelines, and to avail the policy community of recent major advances in quantitative and expert synthesis to overhaul the process and thereby better equip multi-national efforts to limit climate change.

完善国家温室气体清单。

温室气体清单的重要性不可夸大：清单的编制过程为政府提供了一些用于实现减排目标的战略。政府间气候变化专门委员会（IPCC）致力于开发和完善国际公认的计算和报告温室气体排放量和清除量的方法。我们认为，这些指南不具备处理大多数国家/地区制定国家温室气体清单的任务。库存指南对于实施气候行动至关重要，我们强调了改善其及时性和准确性的机会。此类改革应提供手段，以更好地理解和推动各国在实现其巴黎承诺方面取得的进展。
