See our press release on this letter: English / Deutsch Aviation may have contributed as much as 4.9% to global radiative forcing in 2005 and its carbon dioxide emissions could grow by up to 360% between 2000 and 2050. In 2016, the International Civil Aviation Organization adopted a global scheme requiring airline operators to offset increases in carbon dioxide emissions from international flights above 2020 levels. Here we show that the scheme will only compensate for the emissions increase if robust criteria for the eligibility of offset credits are adopted.

The required mobilisation of funds for a Paris-compatible development urges for an improved coordination between all of the actors involved in the low-emission transition as well as demands comprehensive knowledge base to address the systemic challenge of financing sustainable economic development. This publication is part of a project enhancing the exchange of experiences between experts, business community and civil society policymakers to improve the assessment and design of domestic climate finance investment environments. It describes existing methods to track climate finance and...

In this policy brief, the Natural Resources Defense Council (NRDC) and NewClimate Institute assess 24 practical and realistic actions to implement between now and 2030 as key elements to cut greenhouse (GHG) emissions significantly by 2030. They include such actions as deploying more renewable energy, transitioning away from coal, boosting energy efficiency, accelerating electric vehicle deployment, and ending deforestation. Main findings: The world can get on a 2℃ pathway by 2030 with “On Track” and “Scale Up” actions The implementation of just 19 of these actions can put the world on track...

The Plataforma Escenarios Energéticos Argentina 2040 initiative developed different scenarios for the future of the energy sector in Argentina. NewClimate was asked to write a comment on the Paris compatibility of the scenarios. Content: In the context of the A2A project, NewClimate Institute worked closely together with the Plataforma Escenarios Energéticos Argentina 2040, an initiative launched in 2011 with the objective to generate plural public debate on Argentina's energy future. The dialogue platform offers technical support and input to decision making processes and aims to support the...

Non-state and subnational climate actors have become central to global climate change governance. Quantitatively assessing climate mitigation undertaken by these entities is critical to understand the credibility of this trend. In this Perspective, we make recommendations regarding five main areas of research and methodological development related to evaluating nonstate and subnational climate actions: defining clear boundaries and terminology; use of common methodologies to aggregate and assess non-state and subnational contributions; systematically dealing with issues of overlap; estimating...

This study compares projected GHG emissions in the G20 economies under current climate policies to those under the GHG targets outlined in the nationally determined contributions (NDCs). It is based on an assessment of official governmental estimates and independent national and global studies. Findings: Highlights: Almost all G20 members are making progress in implementing climate policies. Eight G20 members are on track to meet their unconditional NDC targets. The other G20 members require enhanced policies to achieve their NDC targets. For many G20 members emissions continue to increase...

Gustavo De Vivero works on low-carbon development and policy analysis. As an expert in power systems he focuses on policy, market design and technoeconomic analysis of power systems as key enablers to the energy transition. His expertise covers, among others, producing quantitative and qualitative policy assessments, performing energy systems modelling and providing support to national governments to increase their climate ambition and to drive the energy transition. Gustavo is also part of the Climate Action Tracker team that evaluates national climate change efforts and quantifies GHG...

In this briefing, the Climate Action Tracker's (CAT) estimate of the total warming of the aggregate effect of Paris Agreement commitments and of real-world policy show little change. If all governments achieved their Paris Agreement commitments the world will likely warm 3.0°C—twice the 1.5°C limit they agreed in Paris. Projections Underneath the lack of progress at the global level, however, the CAT has detected real movement in a number of countries which, if extended, could bend the global emissions curve downward. Of the 32 countries the Climate Action Tracker follows, no government has...

Developed by NewClimate Institute, Germanwatch and CAN, the index ties in with the global Climate Change Performance Index by Germanwatch, a rating of the 58 largest emitters of GHG emissions globally that has been published annually since 2006. Description: Three years after the adoption of the Paris Agreement, global climate action is not yet sufficient to limit global warming to well below 2°C and to pursue efforts to limit warming to 1.5°C. In order to achieve the Paris targets, more ambitious climate action is needed. In the context of the newly released special report Global Warming of 1...

The NDC Update Report tracks the progress on the implementation of Nationally Determined Contributions (NDCs) to the Paris Agreement. The theme of this edition is "Ambition": We look ahead and explore whether governments are ready for the next round of pledges and where support and preparation could focus. Executive summary: In December 2018, two years on from the ratification of the Paris Agreement, and two years from the first call for more ambitious pledges, the international community is cautiously observing collective efforts to reduce emissions. The IPCC report Global Warming of 1.5oC...

The Paris Agreement aims to hold the increase in the global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C. To contribute to the fight against climate change, the MDBs have operated under what this report refers to as a Climate Finance Paradigm. Yet, given the urgency of the challenge and the rate at which the world must reduce emissions, this current paradigm is not enough and a new paradigm is needed. This report describes this new paradigm, called the Paris Alignment Paradigm, and provides recommendations on...

This report by NewClimate Institute, PBL Netherlands Environmental Assessment Agency and the International Institute for Applied Systems Analysis (IIASA) provides an overview of projected greenhouse gas (GHG) emissions in 25 major emitting countries/regions up to 2030, taking into account the emission trajectories based on current policies and the implementation of nationally determined contributions (NDCs). The report concludes that 16 out of the 25 countries and regions analysed are not on track to achieve the NDC targets they have set for themselves. This report updates the 2017 report...
