The report finds that a rapid transition to renewable energy is 2-16 times better for nature and society than a business-as-usual scenario across 27 of 30 metrics, significantly reducing air pollution, biodiversity loss, and climate-related land degradation. While the transition increases demands on critical minerals, water for bioenergy, and river fragmentation from hydropower, the report argues these risks can be mitigated through strategic planning, low-conflict siting, and circular economy practices.

The report finds that limiting global warming to 1.5C requires a rapid decline in oil and gas production, with a minimum 65% reduction by 2050. It argues that developing new oil and gas fields is incompatible with this goal and would likely create stranded assets. To replace fossil fuels, the world must significantly scale up wind and solar deployment; the annual investment gap for these technologies is estimated at USD 450 billion until 2030, a sum that could be covered by redirecting funds currently slated for new fossil fuel exploration (USD 570 billion annually). The report also examines the 'dash for gas' in Europe following the Russian invasion of Ukraine, concluding that existing infrastructure can meet medium-to-long-term demand if consumption is reduced. Finally, it highlights legal risks from investment treaties, which could cost governments up to USD 340 billion in compensation claims, and criticizes the lack of transparency and ambition in corporate net-zero targets.

The policy brief argues that while free allocation in the EU ETS protects against carbon leakage, it mutes the carbon price signal for consumers, leading to underinvestment in material efficiency. To solve this, the authors propose a 'climate contribution'—a weight-based charge on the consumption of carbon-intensive materials sold in Europe. This mechanism would pass carbon costs to users and generate revenue for climate action without the high administrative complexity or trade conflict risks associated with border-focused CBAMs. The brief compares this approach against three other CBAM scenarios, concluding that combining dynamic free allocation with a climate contribution maintains a level playing field for exports and avoids 'resource shuffling' and downstream leakage.

The report evaluates a proposed wood biorefinery in Estonia with a projected capacity of 750,000 tonnes per year. Using the CEPI methodology, the study finds that the plant would have a negative fossil carbon footprint of -0.39 tonnes of CO2-e per tonne of finished product, primarily because the renewable electricity it exports to the grid replaces oil shale-based power. The plant is also estimated to sequester 1.3 tonnes of biogenic CO2-e per tonne of product. Compared to a 'zero scenario' where wood is exported to Nordic countries, the project is expected to reduce Estonia's overall greenhouse gas emissions by approximately 1.6% and increase the share of renewable electricity in national consumption to 26%.

The analysis finds that pursuing a net zero emissions pathway by 2050 in Ethiopia would increase the average real annual GDP growth rate by 1.4 percent relative to a business-as-usual scenario. While the NZE pathway requires an additional US$66.98 billion in cumulative investment costs by 2050, it is projected to generate $111 billion in cumulative co-benefits through increased real GDP and avoid $89 billion in costs, primarily in energy. Social co-benefits include an average of 672,000 additional green jobs and significant increases in disposable incomes (10.5 percent by 2030 and 53.1 percent by 2050). The benefit-cost ratio for investments in mitigation and adaptation is estimated to rise from 1.04 in 2030 to 2.99 by 2050.
