Power grid issues are the leading cause of blackouts
The document asserts that blackouts are predominantly caused by infrastructure failure, human error, and extreme weather, rather than the deployment of variable renewables. It highlights a significant investment gap in electricity grids, noting that while renewable energy investment has more than doubled since 2015, grid investment has only grown by 24%. The briefing argues that modernising grids with storage, interconnections, and decentralised generation can enhance adequacy, operational security, and resilience, including 'black start' capabilities. However, the IEA warns that grids risk becoming the "weak link" in the energy transition due to underinvestment in ageing assets and the inability to keep pace with rising global electricity demand.

Debunking common renewable energy myths
The document argues that common myths about renewable energy are outdated and unsupported by evidence. It provides data showing that solar and wind are now the cheapest sources of new power generation, with costs falling up to 90% since 2010. It asserts that modern grids can manage intermittency through storage and diversification, and that renewables have significantly lower impacts on wildlife, public health, and waste compared to fossil fuels. Specific case studies, such as the April 2025 Iberian Peninsula blackout, are used to demonstrate that grid instability is often caused by technical planning issues rather than the presence of renewables.

Congo Basin deforestation threatens regional rainfall and global cocoa supply
Deforestation in the Congo Basin risks reducing regional rainfall by up to 40%, which could lead to cumulative cocoa yield losses of 3.06 million tonnes across nine African countries by 2050. This supply shock is projected to drive cocoa prices to USD 68.1 per kilogram by 2050, with deforestation accounting for 40.2% of that price. EU importers could face cumulative additional costs of USD 256 billion by 2050. The report argues that investing in forest conservation, particularly community-led restoration, is more cost-effective than inaction, offering avoided costs of USD 1.8 to USD 6 for every dollar invested.

Developing a pathway for food systems transformation
The briefing highlights that while food systems contribute over 30% of global greenhouse gas emissions, there is no cohesive global pathway with clear targets and timelines to reach net zero. Current efforts, such as the FAO roadmap, are deemed insufficient because they omit the need to reduce animal-sourced product consumption and lack key biodiversity targets. The author notes that while over 55 relevant targets exist across frameworks like the Paris Agreement and SDGs, they are disconnected, often non-binding, and lack financial targets. The document calls for a coordinated framework similar to the IEA's energy roadmap to integrate climate, health, and nature goals and minimize trade-offs.

Renewables Bulletin: BRICS Edition
The BRICS bloc generated over half of the world's electricity in 2024, with China dominating renewable energy production. While solar and wind capacity have grown exponentially in China, India, and Brazil since 2015, progress has stalled in Russia and South Africa. Hydropower's share of BRICS renewable generation fell from 82% in 2015 to 45% in 2023 as solar and wind expanded. China leads the bloc in total renewable energy jobs, though Brazil has the highest proportion of such jobs relative to its population.

The IEEJ: Japan's Unrealistic Gas Forecasts
The Institute for Energy Economics Japan (IEEJ) produces energy forecasts with significantly higher gas demand and carbon emissions than those of the IEA, ExxonMobil, and BP. This is driven by higher projected costs for solar and wind, a preference for thermal power as a backup to renewables, and optimistic forecasts for carbon capture and storage (CCS) deployment. The IEEJ maintains close ties to the Japanese government and industry, while Japan remains a major global financier and trader of gas.

Carbon offsets primer
The document examines the systemic failures of carbon offsetting, highlighting that most credits—particularly those for forestry and renewable energy—lack additionality and environmental integrity. It argues that offsetting often leads to an overall increase in emissions by delaying necessary mitigation and allowing continued investment in high-emitting technologies. The briefing concludes that carbon avoidance and reduction offsets have no place in ambitious climate policies, recommending that priority be given to direct emissions cuts and non-market-based climate finance.

EU considers replacing Russian LNG with US LNG
The briefing argues that the EU does not need new US LNG terminal approvals to replace Russian gas imports. US LNG capacity currently under construction (73 bcm) is over four times the volume of Russian LNG the EU imported in 2024 (17.1 bcm). Furthermore, two US projects that began operating in December 2024 alone provide 58% more capacity than those 2024 Russian imports. The document highlights a projected decline in EU gas demand—forecast to drop 29% by 2030 and 67% by 2040 relative to 2024 levels—warning that new long-term contracts beyond 2035 would create a gas supply glut.

Zero Carbon Zero Cost: Rooftop Solar Savings for Japanese Households
Zero Carbon Analytics finds that Japanese households with rooftop solar panels would have saved nearly 135% compared to those without in FY 2020, resulting in a net benefit of JPY 37,422 (USD 353). The report argues that Japan, which has the lowest clean energy share among G7 countries, can accelerate its energy transition by leveraging rooftop solar to overcome mountainous terrain constraints. It highlights the role of policy incentives like feed-in-tariffs (FiT) and tax credits in driving adoption in the US, EU, and UK, and suggests that Japan needs low-cost finance to reduce upfront costs and avoid diverting support toward unproven technologies like hydrogen.

Oil and gas fuelling extreme weather in Brazil
Attribution studies in Brazil indicate that fossil fuel combustion increased the likelihood and intensity of recent floods in Rio Grande do Sul and droughts in the Amazon. Despite these impacts, the Brazilian government continues to support oil and gas expansion, with plans to increase oil production by 63% and gas by 124% by 2032. Petrobras, which controls over 90% of domestic production, is estimated to be responsible for USD 500 billion in climate damages between 2018 and 2023. While Brazil has pledged to reduce emissions by up to 67% by 2035 and has successfully increased wind and solar power to reduce reliance on hydropower, its overall climate policies are rated as 'Insufficient' by Climate Action Tracker.

Net zero progress overblown by inconsistencies in land carbon accounting
The document examines how discrepancies between NDC accounting and IPCC standards lead to an overestimation of land-based carbon sequestration, potentially reducing the global carbon budget by 15-18%. It highlights that current NDC pledges for land-based removal involve approximately 1 billion hectares, which the author claims is impossible without threatening food security and biodiversity. Furthermore, the briefing critiques IPCC Integrated Assessment Models (IAMs) for ignoring land tenure, human rights, and the declining ability of natural sinks to store carbon under rising temperatures, suggesting that sustainable removal potential is up to 79% lower than IPCC estimates.

Empty Promises: Oil & Gas Decarbonization Charter Masks Massive Fossil Fuel Expansion
The Oil & Gas Decarbonization Charter, launched at COP28 by 50 companies, is criticized for focusing on upstream operational emissions while ignoring the larger impact of burning produced fuels. Analysis shows that between January and September 2024, Charter members approved 68 new oil and gas fields containing 14 billion barrels of oil equivalent, which could release nearly 5 billion metric tonnes of CO2. Ten companies, including ADNOC, Saudi Aramco, Petrobras, TotalEnergies, and Shell, are responsible for over 90 percent of these new reserves. These projects represent a commitment of nearly USD 250 billion in expenditure. While the IEA's 1.5ºC pathway requires global production to decline by nearly 20 percent by 2030, Charter companies are projected to increase their production by 17 percent by 2030.

Promises and reality of climate finance flows in Latin America and the Caribbean
The briefing highlights a significant funding gap in Latin America and the Caribbean (LAC), where current climate finance flows represent only 0.5% of regional GDP, far below the 3.7% to 4.9% estimated by ECLAC to meet Nationally Determined Contributions (NDCs). While developed nations eventually met the USD 100 billion annual pledge in 2022, the LAC region's share of international finance (17% between 2016-2020) consists largely of loans (81%), exacerbating regional debt. Financing is heavily concentrated in Brazil, Mexico, Costa Rica, and Colombia, with a strong preference for mitigation over adaptation projects.
