Aside from national and sub-national governments taking action against climate change, large potential for emission reductions exists in the corporate sector. More and more companies are making commitments to contribute to the long-term targets of the Paris Agreement. These include, for instance, pledges to source electricity from renewables, stop sourcing commodities causing deforestation, and increasing energy efficiency across various sectors. This report estimates how large the contribution towards bending the emissions curve to “well below 2°C” from five representative initiatives – RE100...

The Allianz Climate and Energy Monitor ranks G20 member states on their attractiveness as potential destinations for investment in low-carbon electricity infrastructure. It takes into account their current and future investment needs in line with a 2° C global warming trajectory. Consistency with the Paris Agreement, negotiated by 195 countries at the end of 2015, would require a full decarbonization of the global economy before the end of the century. This transformation will be particularly challenging for the energy sector – the largest source of carbon emissions. Every existing and new...

The long-term global climate goals of the Paris Agreement adopted by nearly 200 countries in December 2015, imply enhanced efforts for greenhouse gas emissions reductions in Germany. The phrasing of the long term goals of the Paris Agreement goes beyond prior political consensus. The objective is to limit the global increase in temperature to “well below 2°C” above pre-industrial levels, “pursue efforts to limit the temperature increase to 1.5°C”, as well as to lower the net GHG emissions to zero in the second half of the century. The aim of this brief analysis is to translate the goals of the...

The inaugural report of the 1 Gigaton Coalition, entitled Narrowing the Emissions Gap: Contributions from renewable energy and energy efficiency activities, is now available, and details the emissions saved after analysing nearly 6,000 renewable energy and energy efficiency activities in developing countries. They show the potential for further emissions reductions if programmes and initiatives are supported further to replicate successful projects more widely. The report is based on the current level of activities in renewable energy and energy efficiency in the energy sector. However, after...

This sixth UNEP Emissions Gap Report provides a scientific assessment of the mitigation contributions from the submitted INDCs. As in the previous reports, it then compares the resulting emission levels in 2030 with what science tells us is required to be on track towards the agreed target of a global average temperature increase below 2°C by 2100. The Report also provides data for the aspirational target of keeping the temperature increase below 1.5°C. In addition, the Report presents selected areas where enhanced action can be taken, accelerated and scaled up to close the emissions gap. The...

This paper provides an overview of options to assess mitigation commitments before Paris and beyond. This includes a review of current activities to assess individual INDCs as well as a discussion of some of the attributes and requirements such assessment needs to fulfil. The paper goes on to explore options of how the assessment could be carried out and linked to the UNFCCC process, followed by a discussion of methodological approaches to assess the ambition of mitigation contributions. In conclusion, it provides some recommendations on a feasible and realistic way forward drawing out...

This study compared recommendations for good practice climate change mitigation policies from various institutions with the current status of application of these policies by countries. In an initial attempt, a broad set of climate mitigation-related policies covering all sectors were analysed for the 30 major emitting countries that comprise 82% of global GHG emissions. The database that is the basis for this report is available at www.climatepolicydatabase.org.

This report studies the development of criteria for assessing the compatibility of financial investments with the international goal to limit global temperature increase to below 2°C above pre-industrial levels. The findings are intended as a starting point and a key input for a longer term process to develop consensus-based 2°C investing criteria. The focus here is placed on investments in projects and physical assets, in particular of development and climate finance organisations. In order to limit global temperature increase to 2°C, global greenhouse gas (GHG) emissions will have to be...

A highly efficient use of energy is thus fundamental to limit GHG emissions. Yet, energy efficiency receives much less attention than the decarbonization of the energy supply. This study indicates that scenarios with higher energy efficiency mostly show lower abatement costs. This was the result of evaluating the large number of existing scenarios that comply with the internationally agreed 2°C target until 2050. The societal costs of decarbonization in these scenarios vary strongly and a detailed assessment of the potential cost reductions due to EE is lacking. In order to close this gap...

This report elaborated by NewClimate Institute with support from Climate Action Network (CAN) and the Global Call for Climate Action (GCCA), investigates the co-benefits associated with countries' Intended Nationally Determined Contributions (INDCs). This report first provides an overview of the general co-benefits that climate action may have and how they could be used to incentivise further ambitious greenhouse gas (GHG) reductions. We then provide illustrative results for the cobenefits achieved by the INDCs of the U.S., China, the EU, Canada, Japan, India, South Africa and Chile, as well...

This report offers deliberations on what a “fair share” for emissions in 2025 and 2030 could be. It shows, for a selection of ten countries, how their respective INDCs perform if related to different fair share approaches and effort sharing models. These assessments also take into account national mitigation potential and costs and the wider context of socio-­‐economic devel-­‐opment of the countries. Finally, current policies and politics of each country are included in the assessments. Authors: Andrzej Ancygier, Jasmin Cantzler, Hanna Fekete, Markus Hagemann, Niklas Höhne, Daniel Kandy...

Many “non -state actors” - e.g. regions, cities, companies and whole sectors - have committed to reduce their greenhouse gas (GHG) emissions. These activities become increasingly important next to nationally driven actions under the United Nations Framework Convention on Climate Change (UNFCCC). The exact impact of these efforts on current and future emissions is unknown and under-researched. Mitigation activities of regions, cities and companies that are independent of national action are currently not comprehensively reflected in the projection of greenhouse gas emissions of Germany, which...

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 and provide country-level details for three approaches. At this stage, however, it seems utopian to assume that the international community will agree on a single allocation scheme. Here, we investigate an approach that involves a major...

This presentation report was prepared by NewClimate Institute on behalf of the United Nations Framework Convention on Climate Change (UNFCCC) and the United Nations Development Project (UNDP), under the project Experiences and lessons learned in the preparation of INDCs. The report documents the challenges that countries have faced in their INDC preparation process, and lessons learned for overcoming them.

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 corporate GHG emissions within a specific carbon budget (for example, 550–1,300 GtCO2 between 2011 and 2050 for the 2°C target) . Here the authors propose a method for corporate emissions target setting that derives carbon...
