The 11th edition of the UNEP Emissions Gap Report assesses the gap between “where we are likely to be and where we need to be”, which has become known as the ‘emissions gap’. Additionally, this year it examines two areas that are highly relevant for bridging the gap, especially during the COVID-19 pandemic: the shipping and aviation sectors. Read More
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.

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.

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. Read More
This report explores the introduction of carbon taxes with a national offset component and their interactions with other policy areas, and makes recommendations on this topic. In this task, the study focuses on the approaches Chile, Mexico and South Africa have chosen for elaborating their carbon taxes. Read More
The objective of this seventh UNEP Emissions Gap Report is to provide an up-to-date scientific assessment of the global progress towards the emissions reductions required to be on track to meet the long-term goal of the UNFCCC. Read More
Article published in Climate Policy on resolving the inconsistency between global goals and national contributions. We find that many of the contributions are conservative and in some cases may be overachieved. We also find that the preparation of the INDCs has advanced national climate policy-making, notably in developing countries. Read More
The Paris climate agreement aims at holding global warming to well below 2 degrees Celsius and to “pursue efforts” to limit it to 1.5 degrees Celsius. To accomplish this, countries have submitted Intended Nationally Determined Contributions (INDCs) outlining their post-2020 climate action. Here we assess the effect of current INDCs on reducing aggregate greenhouse gas… Read More
While energy-sector emissions remain the biggest source of climate change, many least-developed countries still invest in fossil-fuel development paths. These countries generally have high levels of fossil-fuel technology lock-in and low capacities to change, making the shift to sustainable energy difficult. Tanzania, a telling example, is projected to triple fossil-fuel power production in the next… Read More
Achieving the collective goal of limiting warming to below 2 °C or 1.5 °C compared to pre-industrial levels requires a transition towards a fully decarbonized world. Annual greenhouse gas emissions on such a path in 2025 or 2030 can be allocated to individual countries using a variety of allocation schemes. We reanalyse the IPCC literature allocation database… Read More
Corporate climate action is increasingly considered important in driving the transition towards a low-carbon economy. For this, it is critical to ensure translation of global goals to greenhouse-gas (GHG) emissions reduction targets at company level. At the moment, however, there is a lack of clear methods to derive consistent corporate target setting that keeps cumulative… Read More
This article assesses Japan’s carbon budgets up to 2100 in the global efforts to achieve the 2°C target under different effort-sharing approaches based on long-term GHG mitigation scenarios published in 13 studies. The article also presents exemplary emission trajectories for Japan to stay within the calculated Budget. Read More
Track 0’s Founder and CEO Farhana Yamin and two of Track 0’s advisors, Erik Haites and Niklas Höhne, have compiled a Paris Agreement which offers one possible way in which the 90 pages of unwieldy text can be whittled down to produce an ambitious, yet politically balanced and comprehensive agreement. Read More
Main report – May 2015 Download This report elaborated by PBL, NewClimate Institute, IIASA and Ecofys provides an overview of projected greenhouse gas (GHG) emissions of seven major emitting countries (Brazil, China, India, Indonesia, Japan, Mexico, and the United States) out to 2030, taking into account the emissions trajectories based on current and selected enhanced policies.… Read More
Niklas Höhne and Hanna Fekete are authors of this year’s UNEP Emissions Gap Report which informs governments and the wider community on how far the response to climate change has progressed over the past 12 months. Read More
NewClimate Institute staff prepared the process guidance paper entitled ‘Process guidance for Intended Nationally Determined Contributions (INDCs)’ for the International Partnership on Mitigation and MRV. Read More
The international carbon market is in a state of transition, moving away from project-based carbon market mechanisms like the Clean Development Mechanism (CDM) towards new international mechanisms which have yet to be defined and finalised. Read More

This research analysed the question if approaches for carbon market-based mechanisms exist that allow the generation of net emission reductions in host countries while keeping project initiation attractive. We present a criteria-based assessment method and apply it for four generic options in existing mechanisms and derive implications for future mechanism frameworks. Read More
Naess, L.O., Hagemann, M., Harvey, B., Urban, F., Hendel-Blackford, S. and Höhne, N.
This CDI Practice Paper addresses the role of tools in supporting interventions to achieve the ‘triple wins’ of adaptation, mitigation and development. Over recent years there has been a proliferation of guidance tools to support adaptation or mitigation, increasingly in a development context, but little work on the role tools play in helping to bridge the gap between these three areas in practice.

Many of the major greenhouse gas emitting countries have planned and/or implemented domestic mitigation policies, such as carbon taxes, feed-in tariffs, or standards. This study analyses whether the most effective national climate and energy policies are sufficient to stay on track for meeting the emission reduction proposals (pledges) that countries made for 2020.
