This article shows how a strengthening of existing plans by a global roll-out of successful, regional sector policies can ease the implementation challenge of reaching the Paris climate goals. The novel element of it is to integrate such detailed policy packages until 2030 into pathways that reach long-term targets until 2100 using an integrated assessment modelling framework. The study is only a first step in connecting the analysis of mitigation pathways towards the Paris climate goals with an assessment of the implementability of near to medium term (2020–2050) climate action that would be...

This article identifies and quantifies the 10 most important benchmarks for climate action to be taken by 2020 – 2025 to keep the window open for a 1.5°C-consistent GHG emission pathway. Abstract We conducted a comprehensive review of existing emissions scenarios, scanned all sectors and the respective necessary transitions, and distilled the most important short-term benchmarks for action in line with the long-term perspective of the required global low-carbon transition. Owing to the limited carbon budget, combined with the inertia of existing systems, global energy economic models find only...

This briefing paper introduces the Technology Needs Database (TND) compiled to support activities of the National Designated Entity (NDE) of Germany for technology transfer under the UNFCCC. The database captures technology needs identified by developing countries in Technology Needs Assessments (TNAs) and (intended) Nationally Determined Contributions ((i)NDCs) to achieve national climate goals in the areas of climate change mitigation and adaptation. Key findings Mitigation In the field of mitigation, the summary statistics reveal that technology needs are most frequently identified in the...

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...

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...

In this study, we have translated the global ambition of the Paris Agreement into concrete sectoral targets applicable to the Netherlands. This has been done by comparing projected pathways of climate-relevant indicators from various authoritative literature sources to what would be needed in order to be compatible with the Paris Agreement’s long-term goals. The Netherlands faces a steep road ahead if the economy is to develop in a way that is compatible with the Paris Agreement. While promising developments have taken place in certain sectors - i.e. in transport, where the country is a...

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...
