Beyond national climate action: the impact of region, city, and business commitments on global greenhouse gas emissions Mar 2020 - This article quantifies the net aggregate impact in 2030 of commitments by individual non-state and subnational actors (e.g. regions, cities and businesses, collectively referred to as ‘NSAs’) to reduce greenhouse gas (GHG) emissions.
The Emissions Gap Report 2019: A UN Environment Synthesis Report Nov 2019 - This is the tenth edition of the United Nations Environment Programme (UNEP) Emissions Gap Report. It provides the latest assessment of scientific studies on current and estimated future greenhouse gas (GHG) 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.
Global climate action from cities, regions and businesses – 2019 Sep 2019 - This report is the second global analysis of local and regional government and corporate climate contributions, updating “Global Climate Action from Cities, Regions, and Companies” launched at the 2018 Global Climate Action Summit.
How could the concept of an “overall mitigation in global emissions” (OMGE) be operationalized under the Paris Agreement? Jun 2019 - This paper addresses questions that have been raised in relation to OMGE. It draws on a study conducted by Lambert Schneider and NewClimate Institute.
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...
Coordinating finance for sustainable refrigeration and air conditioning Sep 2018 - This paper provides an overview of the current situation and options for financing sustainable refrigeration and air conditioning. 
Global climate action from cities, regions and businesses Aug 2018 - This report is the most comprehensive assessment of 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.
