The report examines the UK's progress toward an 80 percent emission reduction by 2050 as mandated by the Climate Change Act 2008. While the UK is projected to meet carbon budgets up to 2022, the analysis indicates that meeting the fourth carbon budget (2023–27) will require an acceleration of emission reductions and the timely implementation of additional measures. Key policy levers discussed include electricity market reform, the Green Deal, the Energy Company Obligation, the EU Emissions Trading System, and the EU Renewable Energy Directive.

The document defines cap-and-trade as a market-based system that sets a maximum limit on greenhouse gas emissions, creating a carbon price through the supply and demand of emission allowances. It details the differences between upstream and downstream regulation, compares cap-and-trade to carbon taxes, and lists existing programs such as the EU-ETS and RGGI.

Developed countries reported mobilising US$ 35 billion in Fast-Start Finance (FSF) from 2010 to 2012, exceeding the US$ 30 billion target. However, the report finds that much of this funding was not 'new and additional', often recycling existing pledges or ODA. Mitigation received the vast majority of funding (over 70%), while adaptation received only 18%. The distribution of funds closely mirrored traditional Official Development Assistance (ODA) patterns, showing weak correlations with recipient country vulnerability or greenhouse gas emission levels. The top five contributors—Japan, USA, UK, Norway, and Germany—accounted for nearly 80% of the total, with significant divergence in how they defined and reported eligible climate finance.
