The report analyzes the energy strategy of the Three Seas Initiative (3SI) countries, finding that planned LNG and pipeline capacity will significantly exceed projected gas demand by 2030. It warns that this creates a risk of stranded assets and security vulnerabilities due to global price volatility. The author advocates for shifting investment from gas infrastructure to wind, solar, and grid interconnectors, noting that 3SI countries could reach a 67% renewable electricity share by 2030.

Bulgaria is at a pivotal energy transition point as coal's share of electricity generation fell below 30% in 2023. While solar power has grown rapidly, wind energy has stagnated since 2012. The report highlights a technical offshore wind potential of 4.3-5 GW in the maritime exclusive economic zone near Romania, which could lower wholesale power prices by 45% by 2030 if combined with increased onshore wind and better interconnections. To achieve this, the report recommends the swift adoption of a new offshore wind law, the implementation of Contracts-for-Difference (CfDs), and the update of the National Energy and Climate Plan with explicit 2030 targets.

The document argues that large-scale deployment of CCS is essential for Europe to reach climate neutrality by 2050, yet current draft NECPs show significant gaps in targets and planning. It provides a framework for Member States to assess storage capacity, map projects, engage stakeholders, and establish financing and regional cooperation for CO2 transport and storage networks.

The document argues that clean hydrogen should be treated as a 'precious molecule' and prioritised for 'no regrets' hard-to-abate industrial sectors rather than being deployed indiscriminately. It recommends that EU Member States move beyond a sole focus on renewable ('green') hydrogen to include other low-carbon pathways, such as nuclear ('pink') and natural gas with carbon capture ('blue'), to avoid resource constraints. The guide emphasises locating production close to end-users to minimise transport inefficiencies and suggests that hydrogen in transport be limited to heavy-duty trucking, aviation, and shipping, while light-duty vehicles should prioritise electrification. Finally, it advises leveraging EU and national support mechanisms to fund 'champion' projects across the entire value chain.

The document argues that superhot rock (SHR) energy—a subset of Engineered Geothermal Systems that accesses rock temperatures exceeding 400°C—could provide a zero-carbon, firm, and energy-dense power source available globally. It notes a significant gap in current EU planning, where only one country (Italy) mentions SHR in its draft NECP, despite 20 countries planning for geothermal energy. The guide recommends that Member States fund pilot demonstrations, map national SHR resources, contribute to a centralised EU geothermal data repository, develop national geothermal strategies, and create stakeholder collaboration platforms. It highlights that SHR systems can potentially produce up to ten times the energy of conventional geothermal wells and could support the production of clean hydrogen.

The report examines the planetary boundaries concept, which identifies nine bio-physical systems essential to human stability. It notes that as of 2023, six of these nine boundaries have been exceeded globally. The document explores the difficulty of 'downscaling' these global limits to national levels, discussing various allocation principles such as equality, needs, and sovereignty. It specifically evaluates the potential for Estonia to calculate its 'own share' of these boundaries to inform national environmental policy, while highlighting significant data gaps and the lack of a harmonized EU-wide methodology.

The report analyzes the fragmented ecosystem of AI audits, distinguishing between organizational conformity assessments and academic performance evaluations. It details the roles of internal, external, and community auditors, the methodologies used—such as input variation and benchmarking—and the current state of enforceable regulations in the US, Canada, EU, UK, and China. The document argues for a more diverse, trustworthy audit ecosystem with better data access and a focus on global impacts, including environmental and labor concerns, to move beyond 'null compliance'.

The Stockholm Environment Institute (SEI) collaborated with the Estonian government to create the country's first unified carbon footprint calculation methodology and emissions factor database. This tool allows public and private sector organizations to assess their environmental impact on a consistent basis, helping to avoid greenwashing and support EU environmental policy. Initial implementation in the Ministry of Defence and Ministry of Interior has led to measurable reductions in carbon emissions, waste, and water consumption, with the Estonian government aiming to expand these assessments across all ministries.

The document outlines how to make school catering procurement more sustainable in Estonia, aligning with European Commission guidelines and the 'Farm to Fork' strategy. It provides specific technical descriptions and evaluation criteria across several key areas: organic food, low-climate-impact sourcing (short supply chains and seasonal produce), plant-based diets, waste reduction, eco-friendly cleaning supplies, energy and water efficiency, and food education. For each area, it suggests how to set minimum requirements in technical specifications and how to award additional points during the bid evaluation process to incentivize higher environmental standards.

The report finds that while current national targets collectively aim for a doubling of renewable capacity by 2030, they often underestimate the actual pace of deployment. A global tripling to 11,000 GW is considered achievable if governments update targets to reflect recent growth and maintain a 17% annual increase in additions. The analysis identifies specific countries with high potential to increase ambition, such as Australia, Japan, South Korea, and the UAE, while noting that others like India and Saudi Arabia already have targets that aim for a tripling of their 2022 capacity.

The report evaluates solid oxide electrolyzer cell (SOEC) technology, highlighting its superior electrical efficiency when integrated with external heat sources, such as those found in steel, chemical, and nuclear plants. While the technology is more mature than often perceived—leveraging experience from the gigawatt-scale solid oxide fuel cell (SOFC) industry—it faces challenges regarding stack durability due to high-temperature thermal stress and the need to scale from small modules to hundred-megawatt systems. The report finds that raw material supply chains are not a bottleneck and that gigawatt-scale manufacturing is feasible within 18 to 36 months.

The document outlines a comprehensive approach to achieving the '30x30' target, emphasizing that numerical expansion must be coupled with qualitative improvements in governance and management. It details a three-phase implementation timeline (Review, Planning, and Implementation), defines key concepts such as OECMs and human rights-based approaches, and provides guidance on integrating biodiversity conservation with climate goals and national policies.

The report assesses Europe's geological CO2 storage potential, estimating theoretical capacity between 262 and 1520 GtCO2. It compares 'Domestic' (widespread) and 'Export' (limited basins) storage scenarios against 'Prioritised' and 'Technical Potential' demand scenarios. While Europe has sufficient long-term theoretical capacity, current announced projects are insufficient for 2035 demand. The study highlights that widespread domestic storage significantly reduces transport CAPEX compared to export-heavy models, though some countries like Finland and Estonia lack suitable sedimentary basins.

The report assesses Europe's theoretical CO2 storage capacity, estimating it between 262 and 1520 GtCO2, and matches this against industrial and non-industrial CCS demand scenarios for 2035 and 2050. It compares 'Export' scenarios (limited key basins) with 'Domestic' scenarios (widespread storage), finding that while Europe has sufficient long-term theoretical capacity, current announced projects are insufficient for 2035 demand. The analysis highlights that widespread domestic storage could halve transport CAPEX costs compared to export-heavy models, though certain regions like Northern Italy, the German North Sea, and Switzerland may face capacity constraints under high-demand scenarios.

The report argues that Central and Eastern European (CEE) countries can significantly lower wholesale power prices and enhance energy security by accelerating the deployment of wind and solar energy. By targeting 200 GW of capacity by 2030, the region could reach a 63% share of renewables in electricity generation. The analysis emphasizes that cross-country collaboration is essential to unlock over 100 GW of offshore wind potential and that aligning national strategies with EU policy could unlock approximately €137 billion in public funding.

The Stockholm Environment Institute (SEI) 2022 Annual Results Report details the organization's progress across three impact areas: reducing climate risk, promoting sustainable resource use and resilient ecosystems, and improving health and well-being. Key achievements include contributing to the COP27 decision to establish a loss and damage fund, developing the Global Environmental Impacts of Consumption (GEIC) indicator adopted at COP15, and implementing water management master plans in Bolivia. The report highlights the use of digital tools like LEAP, WEAP, and Trase to inform policy in various regions, including Africa, Asia, and Latin America. Organizationally, SEI reports an increase in scientific publications, a diversification of funding sources, and the implementation of a global monitoring, evaluation, and learning (MEL) procedure.

The report examines the fragmented state of Green Public Procurement (GPP) within the EU and proposes recommendations to leverage public purchasing power for decarbonization. Focusing on the construction and road transport sectors—which each account for approximately 12% of government procurement GHG emissions globally—the study analyzes case studies from eight EU Member States to identify best practices for meeting the EU's goal of a 55% reduction in GHG emissions by 2030.

The document examines the gap between EU Green Public Procurement (GPP) targets and actual implementation in eight Member States. It identifies systemic barriers—including fragmented governance, lack of standardized data, and limited procurement officer capacity—while highlighting successful local and national initiatives in Sweden, France, Germany, and others. The brief argues that the EU must harmonize reporting, institute mandatory requirements for high-emitting sectors, and provide better technical support to leverage public spending for climate goals.

The report finds that Green Public Procurement (GPP) in the EU is characterized by a fragmented approach with few binding requirements and significant gaps between national climate targets and actual procurement practices. While some regions like Catalonia and cities like Berlin show high ambition, most Member States rely on voluntary guidelines. The construction and road transport sectors are highlighted as high-impact areas where GPP could drive decarbonization, yet implementation is hindered by a lack of standardized data, insufficient capacity and time for procurement officers, and a lack of mandatory EU-level criteria. The report recommends harmonizing GPP definitions, introducing mandatory carbon criteria, and expanding the scope of EU Directives to include embedded emissions.

In 2022, the EU electricity mix was led by nuclear (22%), gas (20%), coal (16%), and wind (15%), with solar accounting for 7.3%. While solar and wind continued their long-term growth trends, nuclear and hydro experienced significant declines due to plant closures and drought. Coal saw a temporary increase to offset these losses, while gas remained the only fossil fuel to show growth over the last two decades.
