This research paper examines the impact of energy efficiency (EE) on the costs of achieving the internationally agreed 2°C target by 2050, specifically estimating global cost savings up to 2030 by comparing an energy-efficient pathway against an energy-intensive pathway focused on energy supply decarbonization.

This report, produced by PBL, NewClimate Institute, IIASA, and Ecofys, analyzes projected greenhouse gas emissions for seven major emitting countries through 2030. It evaluates the impact of current, planned, and enhanced mitigation policies to determine their potential to narrow the gap between expected emission levels and those required to meet the 2°C climate target.

This briefing by the NewClimate Institute examines the feasibility, timing, and technical requirements for phasing out net global greenhouse gas (GHG) emissions to meet the 2°C temperature target. It defines 'net phase out' as the point where anthropogenic emissions are equal to or smaller than anthropogenic removals, and discusses the role of carbon budgets, renewable energy, and specific sectoral challenges.

The Sovereign Emission Rights Framework is a proposal by Sandbag, submitted to the European Commission in 2013, for an equitable global emissions trading regime. It argues that emissions rights should be distributed based on 1990 population shares and that historical emissions since 1990 should be counted against these budgets to avoid 'hot air' and ensure a fair distribution of the remaining carbon space needed to avoid 2°C of warming.
