The analysis finds that the Pan-Canadian Framework (PCF), if fully implemented, will leave a 2030 emissions gap of 161 million metric tons (MMT), which is 3.7 times larger than the 44 MMT shortfall predicted by the Canadian government. While an 'Extended' scenario—strengthening PCF policies through 2050—comes closer to the 2030 target, it still falls short of Canada's mid-century goal to reduce emissions by 80-90 percent below 2005 levels. The report highlights that the carbon tax and methane capture are the most effective PCF policies for 2030, and that both the PCF and PCF Extended scenarios would result in significant annual economic savings and thousands of lives saved by 2050 due to reduced particulate matter emissions.

The document analyzes the potential impact of the Trump administration's reversal of climate policies, such as the repeal of the Clean Power Plan, on U.S. emissions. It synthesizes data from seven organizations, estimating that 2025 emissions under Trump's policies would range from 5.6 to 6.8 GtCO2e, exceeding the U.S. Paris Agreement target. It also examines the potential for states, cities, and companies—represented by the 'We Are Still In' campaign—to offset these increases through clean energy transitions and local policy defense.

The report finds that 16 of the 25 major emitting countries and regions analysed are not on track to meet their self-determined NDC targets. While some countries like Brazil, China, and India are likely to achieve their targets with current policies, others, including the US, EU, and Canada, require additional measures. Furthermore, current policies are projected to fail to prevent emissions from increasing up to 2030 relative to 2010 levels in both developing and OECD nations, with only Japan and the EU projected to see further decreases.

One year after the Paris Agreement's adoption, the Climate Action Tracker (CAT) finds that national climate policies have made little progress. If NDCs are fully implemented, global warming by 2100 is estimated at 2.8°C, while current policies would lead to 3.6°C. A significant emissions gap remains for 2025 and 2030. The report highlights specific national trajectories, noting that most assessed NDCs are inadequate or medium in ambition, with particular concerns regarding the US, Russia, and Saudi Arabia, while noting positive renewable energy growth in India.

The report identifies a 'methane emission gap' between the Obama Administration's goal to reduce oil and gas methane pollution by 40–45% from 2012 levels by 2025 and the actual impact of its proposed regulations. It finds that proposed standards primarily target new and modified sources, while existing sources are projected to represent 90% of the sector's total methane emissions in 2018. To close the gap of at least 75 million metric tons CO2e, the report recommends requiring leak detection and repair, non-emitting pneumatic technologies, and the capture of gas from oil wells for existing sources.

Pennsylvania is required to reduce power sector emissions by 24-25 percent below 2012 levels by 2030 under the Clean Power Plan. Analysis indicates that current clean energy policies and improved power plant efficiency could achieve a 13 percent reduction by 2030. To fully meet or exceed targets, the state can expand its energy efficiency programs (Act 129) and alternative energy portfolio standard (AEPS) after 2021, potentially cutting emissions by 46 percent below 2012 levels by 2030. Such measures are described as cost-effective, with potential for the state to earn over $160 million annually by selling unused emissions allowances between 2022 and 2030.

The document analyzes Mexico's 2015 INDC, which commits to unconditional reductions of greenhouse gas (GHG) emissions by 22% and black carbon by 51% relative to a 2030 baseline. While noting Mexico's leadership as the first developing country to submit an INDC and its identification of a 2026 emissions peak, the analysis warns that current policy trajectories projected by external sources suggest emissions would continue to increase without further action. The authors recommend formalizing a robust baseline policy to avoid high-carbon lock-in and improving transparency regarding the expected emissions trajectory and the specific conditions required to meet conditional targets.

The 2015 update to the Massachusetts Clean Energy and Climate Plan for 2020 (CECP Update) outlines a comprehensive strategy to reduce greenhouse gas (GHG) emissions by at least 25% below 1990 levels by 2020. The plan identifies key drivers for these reductions, most notably vehicle GHG emission standards and the import of clean electricity. It also provides a framework for long-term goals, aiming for an 80% reduction by 2050 through a strategy of reducing energy consumption, decarbonizing the electricity supply, and electrifying transportation and heating. The report includes detailed assessments of building efficiency, transportation, electricity generation, and non-energy emissions, as well as research on land use and carbon storage in terrestrial and wetland ecosystems.

The report analyzes the implementation of the Effort Sharing Decision (ESD), which targets non-ETS sectors responsible for nearly 60% of EU emissions. While 15 Member States are projected to over-achieve their 2020 targets, others face significant gaps, particularly in road transport and buildings. The document highlights that while the overall EU 2020 target is likely to be met, several countries rely on flexibility mechanisms or planned additional measures rather than existing policies to close their emission gaps.
