Research, analysis and innovative thought on options discussed at the international climate negotiations, including detailed modalities of the ambition-raising mechanism under the 2015 Paris Agreement towards the 2/1.5 °C limit.
If the emissions gap is to be closed and the global warming kept below 2/1.5 °C, as the 2015 Paris Agreement aims, raising the ambition on action against climate change is urgent. The next 10 years will show if a transition towards a sustainable, greenhouse gas-free society can be made.The Paris Agreement puts into place some essential elements to ratchet up national ambition towards the 2/1.5 °C limit and net zero emissions in the second half of this century. However, there is much further work to be done on the exact modalities to effectively raise mitigation ambition. We support the successful implementation of the Paris Agreement through research and analysis, in particular modalities of review and the global stocktake, the nature and level of commitment in Nationally Determined Contributions (NDCs), and the possible shape of a long term goal of net zero greenhouse gas emissions at national level.

The Emissions Gap Report 2018: A UN Environment Synthesis Report Nov 2018- This is the 9th edition of the UN Environment Emissions Gap Report. It assesses the latest scientific studies on current and estimated future greenhouse gas emissions and compares these with the emission levels permissible for the world to progress on a least-cost pathway to achieve the goals of the Paris Agreement. 
Operationalising an ‘overall mitigation in global emissions’ under Article 6 of the Paris Agreement Nov 2018- A key requirement of the mechanism established by Article 6.4 of the Paris Agreement is that it shall aim to deliver an overall mitigation in global emissions. This report identifies and discusses key options for operationalising this concept, leading to distinct recommendations to support the ongoing...

Global climate action from cities, regions and businesses Aug 2018- This report is the most comprehensive assessment of these non-state actor commitments to reduce greenhouse gases to date. Key results show that action by cities, states, regions and business can go a long way towards meeting the goals of the Paris Climate Agreement, but their actions alone are not enough to hold global temperature increase to well-below 2°C and work towards limiting it to 1.5° C.
Setting the Paris Agreement in Motion: Key Requirements for the Implementing Guidelines Aug 2018- With the December 2018 deadline to operationalize the Paris Agreement looming, climate negotiators are faced with the herculean task of pulling together volumes of draft notes and the disparate views of negotiating blocs into comprehensive implementing guidelines to be adopted later this year. A new paper from the Project for Advancing Climate Transparency provides both an overarching vision and practical suggestions for what should be included in the main pillars of the implementing guidelines of the Paris Agreement. 
National climate change mitigation legislation, strategy and targets: a global update Aug 2018- This paper analyses trends in adoption of national climate legislation and strategies, GHG targets, and renewable and energy efficiency targets in almost all UNFCCC Parties, focusing on the period from 2007 to 2017.
Opportunities and safeguards for ambition raising through Article 6 May 2018- In this paper, we discuss the ambition raising implications to engage in voluntary cooperation under Article 6 for the originating Parties. The paper shows why Article 6 should focus on driving mitigation in otherwise inaccessible abatement options and why it is critical that support should only last for a limited time period, after which own action must kick-in.
The EU can increase its climate targets to be in line with a global 1.5°C target May 2018- This project analyses best practice policies across Europe and how far extending them to all EU member states could support EU Greenhouse Gases (GHG) and energy targets. It finds that the EU can go much further than its current commitments in terms of GHG reductions: it has the potential to reach -55% to -62% below 1990 by 2030, consistent with the Paris commitment of staying “well below 2°C, pursuing 1.5°C”.
Deutschland droht das Pariser Klimaschutzabkommen zu unterminieren Jan 2018- Mit der Abkehr der potentiellen neuen großen Koalition vom Klimaziel für 2020 gibt Deutschland nun offiziell die Rolle als internationaler Klimaschutzvorreiter auf.

The Emissions Gap Report 2017: A UN Environment Synthesis Report Nov 2017- The goal of the Paris Agreement on climate change, as agreed at the Conference of the Parties in 2015, is to keep global temperature rise this century to well below 2 degrees Celsius above pre-industrial levels. It also calls for efforts to limit the temperature increase even further to 1.5 degrees Celsius.
The UN Environment Emissions Gap Report 2017 presents an assessment of current national mitigation efforts and the ambitions countries have presented in their Nationally Determined Contributions, which form the foundation of the Paris Agreement.
