Tracking climate action
NDC Design Jul 2021 - We evaluate the NDCs along key elements that are critical for the success of the NDC ambition cycle: 1. Increased mitigation ambition; 2. Comprehensiveness; 3. Implementation plan; and 4. Transparency.
Global climate action from cities, regions and businesses – 2021 Jun 2021 - This report is the third and the latest edition of the series since 2018 that take stock of climate action by cities, regions and businesses and their global aggregate impact on greenhouse gas emissions. The 2021 edition focuses on the progress of non-state and subnational actors toward their emissions reduction targets.
Greenhouse gas emission scenarios in nine key non-G20 countries: An assessment of progress toward 2030 climate targets Jun 2021 - This study compares greenhouse gas (GHG) emissions projections in 2030 under current policies and those under 2030 mitigation targets for nine key non-G20 countries, that collectively account for about 5 % of global total emissions today. These include the four largest non-G20 fossil CO2 emitting Parties to the UN climate convention pre-Paris Agreement (Iran, Kazakhstan, Thailand and Ukraine) and one of the largest land-use GHG emitters in the world (Democratic Republic of the Congo).
The Challenges of Assessing “Collective Progress”: Design Options for an effective Global Stocktake process under the UNFCCC May 2021 - This paper examines the questions of what an effective Global Stocktake process would look like, and what information and data are needed to support it.
Climate Action Tracker Global update: Climate Summit Momentum May 2021 - Climate action announcements at US President Biden’s Leaders Summit on Climate, together with those announced since September last year, have improved the Climate Action Tracker’s warming estimate by 0.2°C. End of century warming from these Paris Agreement pledges and targets is now estimated to be 2.4°C.
A review of successful climate change mitigation policies in major emitting economies and the potential of global replication Jan 2021 - This journal article in ‘Renewable and Sustainable Energy Reviews’ looks at climate change mitigation policies in five major emitting economies and the potential of global replication of sectors’ progress.
Decreasing costs of renewables in Argentina (two reports) Dec 2020 - The research looks at how cost reductions for renewable energy technologies impact energy planning and climate policy in Argentina, including in the NDC process. 
Subnational and non-state action in the EU Dec 2020 - This working paper describes the landscape, (additional) GHG emission reduction potential, and progress towards target realisation of subnational and non-state actors in the EU. 
The Emissions Gap Report 2020 Dec 2020 - The 11th edition of the UNEP Emissions Gap Report assesses the gap between “where we are likely to be and where we need to be”, which has become known as the ‘emissions gap’. Additionally, this year it examines two areas that are highly relevant for bridging the gap, especially during the COVID-19 pandemic: the shipping and aviation sectors.
The Climate Change Performance Index 2021 Dec 2020 - Developed by Germanwatch, NewClimate Institute and CAN, the index rates 57 greenhouse emitters globally since 2005.
