作为一周的钥匙climate talks wrapped up in Bonn, Germany, today, we’re within the last 100 days before the December必威官网是真的吗巴黎气候峰会– known as COP21 -- where countries aim to reach a new international climate agreement. The Bonn negotiations made important progress in clarifying the core structure for the Paris pact. Ministers and heads of state can build on this progress in the series of high-level meetings inNew York Cityand elsewhere in the weeks ahead. However, time is short. Countries will need to intensify and focus their efforts to set the stage for success in December.

While progress was uneven at times, the Bonn negotiators identified the most essential issues and began crafting a coherent architecture for the agreement. It was as though they were in a garage attempting to build an engine (battery powered of course), with parts lying about. Their task was to distinguish the various pieces, put them into clear categories, and then figure out how they should be ordered to build the engine. It’s a work in progress. The pieces are coming together, though you can’t see exactly what the final product will look like at this point.

The sorting and assembly accomplished lays the groundwork for a negotiating session in Bonn next month, the last preparatory meeting for COP 21. This week’s talks ended on a positive note as negotiators gave a clear mandate to the co-chairs of the negotiating process to prepare a new, concise negotiating document. This will help negotiators hit the ground running when they head back to Bonn.

Here are five of the key issues addressed at this week’s meeting:

  • Cycles of Improvement。Negotiations continued on a process to review and update or ramp up action at regular five-year intervals. A central question is whether countries will be required to revisit and consider upgrading their national mitigation commitments at these times. Negotiators also discussed creating specific processes to regularly enhance adaptation and finance.

  • Long-term goal。许多国家确定了一个长期目标，以深层减少排放为协议的关键部分。在最近之后，采用长期目标的势头已经发展必威官网是真的吗巴西和德国的气候声明, which included support for decarbonization over the course of the century in a fair and equitable way.

  • 透明度和问责制。有一个新兴的愿景，随着时间的流逝，各国以一种透明的衡量和报告国家的排放量来汇聚。

  • 金融。Progress on refining the finance section of the negotiating text was slow in Bonn, underlining the continued difficulty of reaching agreement on this issue. However, countries made progress in identifying the main issues that they want to see reflected in the Paris outcome. A central focus needs to be on how the outcomes in Paris can mobilize and shift investments at the scale needed to decarbonize economies and enhance climate resilience for all. Most immediately, this requires new pledges to meet the existing commitment to mobilize $100 billion a year by 2020.

  • Adaptation and loss and damage。There were productive discussions about how to incorporate adaptation in the agreement. Meanwhile, countries came forward with concrete proposals to address climate impacts that are difficult or impossible to adapt to, known as loss and damage. The proposals showed some potential for finding common ground on loss and damage, though this will remain a complicated issue requiring constructive solutions on the way to Paris.

十月的谈判会议对于在这些关键问题和其他问题上取得成功至关重要，但是还有许多其他即将到来的机会对于为协议建立势头至关重要。环境部长将在本周末在巴黎聚会，讨论金融和适应问题，许多国家元首将在本月晚些时候在纽约举行的联合国大会和可持续发展峰会上召集午餐，主要经济论坛将在后来开会。2015年气候协议的同一周。必威官网是真的吗财务部长还在今年晚些时候在世界银行/国际货币基金组织年度会议的场外召集秘鲁的利马，讨论气候融资。必威官网是真的吗

所有这些都是促进积极的政治氛围和具体进步的时刻，我们需要进入巴黎气候峰会。必威官网是真的吗除国际聚会外，行动还在国家一级聚集。超过50个国家提出了自己的国家气候计划 -必威官网是真的吗预定的国家确定的贡献（INDC）- 预计在9月会有40个。

The negotiations in Bonn this week set the foundation for an agreement in Paris that can drive the world toward a low-carbon economy.
