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. Key messages: The study 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”. The key to realize these reductions is to apply EU-wide the best practice policies identified in various Member States including The Netherlands, Denmark, UK, Germany...

As part of its decarbonisation series , the Climate Action Tracker released an examination of the steel and cement sectors. The report warns that deploying current technologies to decarbonise the steel and cement industries is likely to be not sufficient to meet the Paris Agreement’s 1.5˚C limit. Key messages: The decarbonisation of heavy industry is key to achieving deep cuts in emissions in line with the Paris Agreement’s long-term temperature goal. Reducing these industrial emissions is challenging, as heavy industry emissions are often intrinsically linked to the production process...

As part of its decarbonisation series , the Climate Action Tracker released an examination of gas in the power sector. The report warns that natural gas will have to be phased out along with coal, if the world is to limit warming to 1.5˚C, as spelt out in the Paris Agreement long term temperature goal. Key messages : To achieve the Paris Agreement’s long-term temperature goal, the power sector needs to rapidly transition to being carbon-free by around 2050. This requirement for a complete CO2 emissions phase-out, combined with increasing competition from renewables, results in a dwindling role...

The report based its investigation on the fact that to meet the Paris Agreement’s long-term temperature limit, the global energy system must completely decarbonise by mid-century. The Climate Action Tracker examined the trends driving decarbonisation in three key sectors of the global energy system: power, transportation, and buildings—and looked at what can drive rapid transitions in these areas. Key findings: Power Between 2006 and 2015 installed wind power capacity increased by 600 percent, and solar energy capacity increased by 3500 percent. By 2030, solar PV is projected to become the...

The Climate Action Tracker today spelt out ten important, short-term steps that key sectors need to take to help the world achieve the Paris Agreement’s 1.5˚C limit: All key sectors—energy generation, road transport, buildings, industry, forestry and land use, and commercial agriculture—have to begin major efforts to cut emissions by, latest, 2020. By 2025 they should have accelerated these efforts in order to reach globally aggregated zero carbon dioxide emissions by mid-century, and zero greenhouse gas emissions overall roughly in the 2060s. The CAT scientists warned that in today’s carbon...

Renewable energy and energy efficiency projects implemented in developing countries from 2005 to 2015 will reduce annual greenhouse gas emissions by almost half a gigatonne by 2020, according to the second report by the 1 Gigaton Coalition. These reductions could more than double, reaching one gigatonne, if developed nations deliver on commitments made in Paris last year to provide $100 billion in annual climate financing for developing nations by 2020, finds the report. One gigatonne is roughly equivalent to the emissions generated by transport in the European Union (including aviation) over...

The building sector accounts for around 20% of climate-changing emissions, and its energy demand is likely to double by mid-century without action, according to a Climate Action Tracker (CAT) analysis released today. While the technologies required to make new buildings zero-emissions are all available, the sector is not taking up those technologies as fast as it could and renovation rates are low. Delayed action would put pressure on other sectors to cut emissions, or require negative emissions to keep global warming within the Paris Agreement’s temperature limit. The building sector analysis...

Zero emission vehicles need to take over car market to reach 1.5°C limit: analysis Zero-emission vehicles need to reach a dominant market share by around 2035 for the world to meet the Paris Agreement’s lower warming limit of 1.5°C—and even that could be too late to avoid the need for significant negative emissions, according to new analysis by the Climate Action Tracker (CAT). This transformation of the passenger transport sector would also have to be accompanied by a decarbonisation of the power sector to ensure the electric vehicles (EV) are truly emissions free. In the first of its...

This “Brown to Green” report by Climate Transparency provides a comprehensive overview and assessment for the G20 countries, whether - and how well - they are doing on the journey to transition to a low carbon economy. The report draws on publicly available information and makes use of the assessment work of the Climate Action Tracker (CAT) (operated by NewClimate Institute, Climate Analytics, Ecofys and the Potsdam Institute for Climate Impact Research), Germanwatch’s Climate Change Performance Index (CCPI) and the Overseas Development Institute (ODI). It summarises and compares the findings...

Publication in Local Environment Assessing the concept's cultural legitimacy among stakeholders in the solar energy sector 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 decade. This article assesses the potential to use internationally...

The transition from fossil fuels to cleaner, safer energy technologies is under way. To pinpoint where decarbonization is happening most rapidly—and to extract lessons and best practices that can be applied to other areas of the global economy where progress is needed in the fight against climate change—this study by ClimateWorks, NewClimate Institute, Ecofys, and Climate Analytics compares past projections with actual developments in renewable energy, coal consumption, and passenger vehicles. Key findings include: Decarbonization of the power sector is happening faster than predicted. Reduced...

The international community is negotiating a new global climate agreement to be applicable from 2020 onwards. Parties aim at signing the agreement in December 2015, at the Conference of Parties (COP) in Paris. Until then, countries are already preparing proposals for their individual contributions, their Intended Nationally Determined Contributions (INDCs). The INDCs will, besides other elements, include mitigation contributions as central elements. Negotiations under the ADP have advanced and more concrete discussions are taking place, with the objective to finalise the new climate agreement...

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 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...
