This report by NewClimate Institute, PBL Netherlands Environmental Assessment Agency and the International Institute for Applied Systems Analysis (IIASA) provides an overview of projected greenhouse gas (GHG) emissions in 25 major emitting countries/regions up to 2030, taking into account the emission trajectories based on current policies and t

Authored by NewClimate Institute and The Climate Group and powered by CDP data, ‘States, cities and businesses leading the way: a first look at decentralized climate commitments in the US’ shows that the US can already meet half of its climate commitments under the Paris Agreement by 2025, if the 342 commitments included in the analysis are imp

This briefing presents the results of a preliminary analysis into United States’ subnational and non-state action and its impact on national greenhouse gas emissions, if fully implemented. The analysis covers commitments from individual actors, which set quantitative mitigation targets and for which historical emissions data are available.

The Paris Agreement, adopted in December 2015, calls for increased ambition by all nations worldwide in order to limit global warming to well below 2°C above pre-industrial temperature and to pursue efforts of limiting it to 1.5°C.

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.

This study conducted a comparative assessment of 48 greenhouse gas (GHG) emissions reduction scenarios for 2030 reported in seven studies published since 2011 based on bottom-up energy system analyses. This study conducted two sets of analyses.

This paper assessed Japan’s fair carbon budget consistent with the 2 °C target between 1990 and 2100 under three frequently referred effort-sharing approaches: Converging Per Capita Emissions (CPE); Common but Differentiated Convergence (CDC); and Greenhouse Development Rights (GDRs), as well as the consequent GHG emission pathways up to 2100 fo

This paper comprehensively reviews and assesses Japan’s climate change mitigation policies. Its objectives are threefold. First, it assesses the ambition level of the Warsaw Target in comparison with the Copenhagen Pledge and earlier 2020 mitigation targets.
