The UK has met previous emissions targets primarily through the energy supply sector, but currently lacks credible plans for two-thirds of the reductions needed to reach its 2030 target of a 68% reduction compared to 1990 levels. To address this, the Climate Change Committee (CCC) emphasizes that over 75% of future reductions must come from non-energy sectors, specifically transport, buildings, agriculture, and land. Key recommendations include accelerating the scale-up of methane-suppressing feed, deploying 5 MtCO2 of engineered greenhouse gas removals annually by 2030, and prioritizing low-carbon hydrogen for industrial use-cases like steel and ammonia production rather than home heating. In aviation, while a SAF mandate is planned for 2025 to reach a 10% target by 2030, the brief warns against overreliance on SAF due to feedstock constraints and suggests exploring e-fuels and hydrogen. Nuclear energy is identified as a long-term necessity, requiring a shift toward standardised products to reduce costs.

The Kenya Energy Transition & Investment Plan (ETIP) 2023-2050 outlines a pathway to Net Zero emissions by 2050, requiring approximately USD 600 billion in capital investment. The plan emphasizes an 'Orderly Transition' anchored by six key technologies: renewables, low-carbon hydrogen, battery electric vehicles, clean cooking, carbon capture and storage (CCS), and negative-emission solutions. Key sectoral shifts include a 20-fold increase in power demand met primarily by solar and wind, the total phase-out of fossil-fuel motorcycles by 2045, and a transition from traditional biomass to electric and improved biomass cooking. The transition is projected to create 500,000 net new jobs and reduce domestic oil and gas consumption by approximately 94% compared to a business-as-usual scenario.

Superhot rock energy involves tapping into Earth's deep heat (400°C or hotter) to produce high-density, zero-carbon power. While current geothermal is limited to specific volcanic regions, superhot rock could be accessed worldwide through deep drilling. The report identifies critical engineering needs in drilling, reservoir creation, and materials, suggesting that leveraging unconventional oil and gas expertise could accelerate commercialization.

The roadmap proposes two visions for Colombia's bioenergy sector: one focusing on new technologies (biomethane and biomass-based power/CHP) and another combining these with the expansion of first-generation biofuels. Modeling indicates that while both scenarios increase the bioenergy share in power and gas supply, they cannot prevent an overall decline in bioenergy's share of primary energy demand due to rapid GDP growth and urbanization. The most effective emissions reductions come from power generation and CHP, particularly by avoiding methane release from landfills and animal waste. Scenario I is identified as the most efficient in terms of emissions reduction per additional hectare of land, whereas Scenario II's ambitious biofuel targets would require significant imports as domestic land is insufficient.

The report argues that while fuel cells have high initial capital costs, they can be cost-effective by capturing 'distributed benefits' such as deferring utility distribution investments, providing premium reliability for the digital economy, and meeting strict urban emission standards. It proposes a commercialization path starting with grid-connected systems in commercial buildings and semiconductor fabs, eventually integrating with fuel-cell vehicles through vehicle-to-grid (V2G) systems.

The policy brief highlights the need for a new generation of technology companies to provide N2O MMRV services to address the 'super pollutant' nature of agricultural nitrous oxide. It advocates for a coordinated strategy involving federal agencies, state governments, and private partners to overcome barriers such as the lack of cost-effective sensors and data infrastructure. The brief suggests that improving N2O measurement will benefit voluntary carbon markets, corporate Scope 3 emissions management, and farm profitability by optimizing fertilizer use.
