The G20 countries are responsible for around 80 % of global greenhouse gas emissions, and 85 % of global GDP. In the G20 countries, around 70 % of climate impacts could be avoided by limiting global warming to 1.5°C instead of 3°C. The G20 have a political responsibility as well as economic interest and capability to move the world towards a 1.5°C compatible pathway.

Carbon emissions from the world’s 20 biggest economies are rising. None of the G20 countries have plans that will put them on track to limit global warming to 1.5°C, despite the fact that most are technically capable and have economic incentives. To keep the Paris Agreement’s 1.5°C goal within reach, G20 countries will have to increase their 2030 emission targets by 2020 and significantly scale up mitigation, adaptation and finance over the next decade.

The CCPI is an independent monitoring tool of countries' climate protection performance. It aims to enhance transparency in international climate politics and enables the comparability of climate protection efforts and progress made by individual countries. Based on standardised criteria, the index evaluates and compares the climate protection performance of 56 countries and the EU, which are together responsible for more than 90 percent of global greenhouse gas (GHG) emissions.

Der Allianz Klima- und Energiemonitor vergleicht die G20-Staaten hinsichtlich ihrer Attraktivität für Investitionen in eine emissionsfreie Energie-Infrastruktur. Zudem berechnet er den momentanen und künftigen Investitionsbedarf – davon ausgehend, dass die Klimaziele des Pariser Abkommens, deutlich unter 2 Grad bzw. möglichst 1,5 Grad Erwärmung, eingehalten werden sollen. Der Monitor wurde zum dritten Mal von der Allianz SE in Kooperation mit Germanwatch und dem NewClimate Institute erstellt.

The 24th Conference of the Parties (COP24) will be held from 2 to 14 December 2018 in Katowice, Poland. The task for this summit is to show that, even with political headwinds, the international community is able to respond to the increased urgency of the climate crisis. With a package of three decisions, COP24 will be a success. In this Background Paper, Germanwatch sums up its expectations towards COP24.

The Brown to Green Report is the world’s most comprehensive annual review of G20 climate action, assessing progress on decarbonisation, climate policies, finance, and vulnerability to the impacts of climate change. The report is published annually by Climate Transparency, a global partnership of 14 climate research organisations and NGOs from the majority of G20 countries, many from emerging economies. Germanwatch is one of the main authors.

82% of the G20’s energy supply still comes from fossil fuels, according to the 2018 Brown to Green Report, released today. In Saudi Arabia, Australia and Japan fossil fuels make up even more than 90% of the energy supply, with little or no change in recent years. The 20 major economies play a key role for achieving the Paris targets because they alone account for 80% of global greenhouse gas emissions.

This working paper by Germanwatch and NewClimate Institute studies how Multilateral Development Banks (MDBs) can operationalize their commitment to align financial flows with the Paris Agreement, focusing on alignment with the Paris temperature goal.

In the trial of the Peruvian mountain guide Saúl Luciano Lliuya against the energy company RWE before the Higher Regional Court of Hamm, the court has now announced that it will select the experts for the taking of evidence itself.

Under the Paris Agreement, for the first time climate action was anchored in the context of international law. This requires countries to make their own unique contribution to the prevention of dangerous climate change. The next crucial step to follow this agreement is the rapid implementation by the signing parties of concrete measures to make their individual contributions to the global goal. For the past 13 years, the Climate Change Performance Index (CCPI) has been keeping track of countries’ efforts in combating climate change. The varying initial positions, interests and strategies of the numerous countries make it difficult to distinguish their strengths and weaknesses and the CCPI has been an important tool in contributing to a clearer understanding of national and international climate policy.
