The report outlines a pathway for Lao PDR to reach net zero emissions by 2050, utilizing LEAP and NEMO modelling to compare a Baseline Scenario with a transformative Net Zero Scenario. Key findings highlight the necessity of diversifying the energy mix beyond hydropower, electrifying transport and cooking, and implementing carbon removal technologies. The analysis emphasizes that while hydropower remains dominant, the country must scale up solar, wind, and biomass to ensure resilience against climate-induced droughts. Achieving the target requires significant infrastructure upgrades, including grid modernization and the deployment of direct air capture (DAC) to offset residual industrial and agricultural emissions. The report also addresses critical economic challenges, such as high public debt and currency depreciation, and recommends strengthening regional cooperation through the ASEAN Power Grid and the APAEC framework.

This policy brief, produced to inform the Rio+20 United Nations Conference on Sustainable Development, outlines a long-term vision for transforming global energy systems to achieve sustainability. It argues that a fundamental shift is necessary to address simultaneous challenges of energy access, climate change, air pollution, and energy security, emphasizing that such a transition is technologically and economically achievable but requires integrated policy frameworks and scaled-up investments.

The report analyzes three scenarios—Ordinary Effort, Promoting Sustainability, and Green Growth—to model China's energy demand and carbon emissions through 2020. It finds that while industry will remain the primary energy consumer, aggressive policies in energy efficiency, fuel switching to natural gas, and the expansion of renewables and nuclear power can significantly decouple GDP growth from energy consumption and carbon emissions. Specifically, the Green Growth scenario demonstrates that carbon emissions could increase by only 50% compared to more than doubling under a business-as-usual approach, provided there is substantial investment in clean energy infrastructure and rigorous enforcement of efficiency standards across the industrial, transportation, and building sectors.

The document argues that the steel sector can be almost fully decarbonised by 2050 through a combination of hydrogen-based direct reduced iron (HDRI), carbon capture and storage (CCS), increased steel recycling, and material efficiency. It warns that to avoid stranded assets and catastrophic climate impacts, new blast furnaces without CCS must not be added and existing ones must not be relined after 2025. Policy interventions are required to provide clean electricity and green hydrogen, create lead markets, and implement carbon pricing, with a suggested price of around US$70 to avoid 1.3 Gt CO2 of emissions by 2030. International cooperation, such as the Glasgow Breakthrough on Steel, is highlighted as essential because demand growth is primarily driven by developing economies in Asia.

The policy brief examines how the Baltic States (Estonia, Latvia, and Lithuania) can utilise their renewable energy potential to achieve carbon neutrality by 2050. It argues that current grid infrastructure is insufficient and that significant investments in interconnections with Nordic countries—specifically Sweden and Finland—are essential to balance wind power fluctuations and reduce dependency on non-EU energy sources. The analysis compares various production and interconnection scenarios, finding that a 100% renewable target is feasible if the region integrates more deeply with the Nordic Power System (NPS).

The document assesses how constraints on biomass, specific metals, and water resources may impact the transition to a low-carbon economy. It evaluates various scenarios for biomass production, predicts cumulative deficits for metals like indium and tellurium, and examines the water-energy nexus, using a California case study to demonstrate how technology choices can mitigate water stress while reducing emissions.

The fact sheet outlines three scenarios: a Baseline scenario (BAS) where business-as-usual leads to a 98% likelihood of temperatures increasing by more than 2°C; a Basic Energy Access scenario (BEA) that provides basic energy for all while limiting global GHG emissions to 1,300 Gt CO2; and a Shared Development Agenda scenario (SDA) which aims for a more balanced global income distribution with per capita incomes of at least $10,000 for all nations by 2050.

The analysis estimates that by 2100, the cost of ocean damage under a high-emissions scenario (RCP6) would reach US$ 1,980 billion, compared to US$ 612.2 billion under a low-emissions scenario (RCP2.6). The avoidable damage—the difference between these two pathways—is estimated at US$ 1,367.4 billion per year by 2100, representing 0.25 percent of global GDP. The study focuses on five priceable categories: fisheries, sea-level rise, storms, tourism, and the ocean carbon sink, while explicitly excluding 'priceless' values such as biodiversity. It notes that the poorest countries, including those in Africa, East Asia, the Caribbean, and Pacific island nations, are most vulnerable to these impacts.

This policy brief by the Stockholm Environment Institute describes the application of an integrated water-energy-food-ecosystems (WEFE) nexus modeling approach (LEAP-WEAP-MACRO) to the Syr Darya River Basin. It argues that integrated modeling provides more realistic results than siloed approaches and demonstrates that international cooperation among Central Asian countries can increase water availability, boost agricultural production, and reduce greenhouse gas emissions compared to business-as-usual scenarios.

The report details the creation of a comprehensive modeling framework for the Syr Darya River Basin, integrating the Water Evaluation and Planning (WEAP) platform, the Low Emissions Analysis Platform (LEAP) with the Next Energy Modeling system for Optimization (NEMO), and a macroeconomic model (Macro). This integrated approach allows for the simulation of complex interdependencies between water availability, energy production, and economic outcomes across Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan. The study evaluates six thematic narratives—ranging from business-as-usual to regional cooperation and ecosystem restoration—under four climate projections (Historical, Dry, Average, and Wet). Key findings indicate that pursuing isolated national interests increases water stress, while regional cooperation and efficiency policies significantly reduce unmet irrigation demands, lower greenhouse gas emissions, and boost agricultural value added and GDP.

Nigeria's Long-Term Low Emission Development Strategy (LT-LEDS) establishes a pathway to net-zero emissions by 2060. The strategy analyzes four decarbonization scenarios—Business As Usual (BAU), Current Policy Scenario (CPS), Gas Economy Scenario (GES), and Renewable Energy Scenario (RES)—concluding that the RES, supported by international aid (RES+), offers the most promising balance of low emissions and economic growth. The report details sectoral mitigation measures for power, AFOLU, industry, transport, and waste, alongside a comprehensive adaptation framework to protect the economy, particularly the agriculture sector, from climate-induced GDP losses. Implementation relies on policy, financial, and technological innovations, including carbon pricing and the establishment of a National Climate Change Fund.

Uruguay's Long-Term Climate Strategy (ECLP) establishes a roadmap toward CO2 neutrality by 2050 and stability in CH4 and N2O emissions. The strategy prioritizes climate adaptation and resilience due to the country's high vulnerability, particularly in its agro-industrial and coastal sectors. Key mitigation pathways include a second energy transformation focusing on electromobility and green hydrogen, the gradual substitution of clinker in cement production, and increasing carbon sequestration through native and commercial forestry. The document also emphasizes a 'Just Transition' to manage employment shifts in the energy and waste sectors, while aligning national efforts with the Paris Agreement's Global Goal on Adaptation.

The report examines the energy-agriculture nexus in Africa, focusing on five case study countries: Cameroon, Mali, Sudan, Tanzania, and Zimbabwe. It develops three primary scenarios—Reference, Moderate Improvement, and Accelerated Growth—to project energy needs for on-farm activities, crop processing, and transport. The analysis highlights that while high-input mechanized farming significantly increases commercial energy intensity, food security gains in some contexts, such as Sudan, can be achieved without proportional increases in energy consumption. The document also explores the role of agro-industries and the potential for energy efficiency improvements in irrigation and crop curing.

The report details the creation of the LEAP Ireland 2050 model to simulate GHG emissions from Ireland's energy and agriculture sectors. It evaluates the impact of the 2019 Climate Action Plan (CAP) targets, specifically electric vehicle (EV) penetration and residential retrofitting, while introducing the Application Script Editing Tool (ASET) to improve model topology and sensitivity analysis.

Ethiopia's Long-Term Low Emission and Climate Resilient Development Strategy (2020-2050) establishes a pathway to net-zero emissions by 2050. The strategy analyzes four scenarios: Business-as-Usual (BAU), NDC-aligned, Maximum Ambition, and Late Action. It prioritizes decarbonization in energy, transport, agriculture, forestry, waste, and industrial processes (IPPU). Key pillars include expanding renewable energy, electrifying transport, enhancing carbon sinks through reforestation, and modernizing agriculture. The document emphasizes a 'just transition' through a Women and Youth in Green Jobs Program and identifies a significant financing gap, estimating a total investment requirement of USD 154 billion for the NDC-aligned scenario.

The report calculates the ecological footprint (EF) of the North West region of England, finding it to be 6.2 global hectares (gha) per capita. This level of consumption would require more than three planets if adopted globally. The study identifies food consumption, construction, and transport as the primary drivers of the region's environmental impact, with food being the largest single EF component. It proposes 'Factor Four' efficiency scenarios to reduce these impacts by 2020 and 2050.

The report analyzes the relationship between urban transportation, energy consumption, and emissions in the Kathmandu Valley, Nepal. It finds that while CO2 emissions are relatively low globally, local PM10 levels frequently exceed national standards. The study proposes a 'PACKAGE' scenario—combining travel demand management, modal shifts to high-occupancy public transport, and stricter emission standards—as the most effective way to simultaneously reduce congestion, energy use, and pollutants.

The report analyzes the feasibility of decarbonizing Estonia's electricity production, which was 86.39% dependent on oil shale in 2013. Using the LEAP model and multi-criteria analysis, it compares several scenarios, finding that a 'LowCO2' path could reduce greenhouse gas emissions by 90% compared to 1990 levels by 2050. Achieving this requires phasing out oil shale subsidies, investing in grid interconnections with Latvia and Sweden, and significantly increasing support for energy efficiency and distributed renewable generation.
