The 2025 Britain Talks Climate & Nature report, based on surveys of over 7,000 people and focus groups in England, Scotland, and Wales, examines public sentiment toward climate change and nature. It utilizes a segmentation model of British society to identify how different values influence perceptions of climate policy. The findings indicate that while there is broad concern for the environment and a preference for ambitious climate action, significant anxiety exists regarding the cost of policies and a lack of trust in institutions. The report argues that support for climate action increases when communication is clear, tangible, and focused on local community benefits.

International climate finance for Brazil grew by 84% between the 2019–2020 and 2021–2022 biennia, reaching an average of US$ 5.1 billion per year. This growth was primarily driven by the energy sector, specifically solar and wind power, and was characterized by a shift toward commercial financing instruments. While Western Europe, led by France, was the largest regional provider, the AFOLU sector—responsible for most of Brazil's GHG emissions—received only 11% of the total finance. Public institutions provided 58% of the funds, with multilateral development finance institutions (DFIs) playing a dominant role, while private finance grew fourfold to reach 42% of the total.

Merchant BESS in India became financially viable in 2024 due to falling battery costs and increasing price volatility in the Day Ahead Market (DAM). The report finds that BESS can achieve internal rates of return (IRR) up to 24% by combining energy arbitrage with ancillary services, with shorter-duration systems (1-2 hours) currently offering better returns than 4-hour systems.

The document outlines the existential risk posed by the approximately 12,000 nuclear warheads held by nine nations. It explains the physics of fission and fusion weapons and analyzes the catastrophic effects of detonations, ranging from immediate blast and radiation deaths in urban centers to global climate disruption. The guide highlights the instability of 'launch on warning' postures and the potential for 'nuclear winter' and ozone depletion, arguing that even regional conflicts would cause global famine and societal collapse.

The document presents 'Making Local Climate Action Possible', a toolkit co-designed by Climate Outreach, The Connectives, and UK local government officers. It aims to overcome barriers to business engagement—such as cost pressures and limited capacity—by providing guidance and messaging strategies based on three core principles: demonstrating purpose, empathy, and integrity.

The report examines 50 years of Enhanced Geothermal Systems (EGS) development, synthesizing data from 103 projects to identify trends in drilling speed, cost, and production. It highlights a shift toward commercial viability driven by oil and gas techniques, such as horizontal drilling and multi-well pads, and notes a surge in power purchase agreements (PPAs) totaling over 610 MWe. The analysis emphasizes that while incremental and step-change innovations have improved performance, further research into superhot rock and better data transparency are needed for global scaling.

International climate finance for Brazil averaged US$ 5.1 billion per year in 2021–2022, an 84% increase from the 2019–2020 period. This growth was primarily driven by the energy sector, particularly solar and wind power, and a significant rise in private capital from commercial financial institutions. While Western Europe was the largest regional provider, the report highlights a stark imbalance in sectoral allocation: the AFOLU sector, responsible for most of Brazil's GHG emissions, received only 11% of total finance. The majority of funds were earmarked for mitigation (80%) and delivered via commercial debt and equity, while grants and concessional finance declined by 43%.

International climate finance to Brazil averaged R$ 26.6 billion per year in 2021–2022, an 84% increase from 2019–2020. Growth was primarily driven by the energy sector, specifically solar and wind power, and a significant rise in private commercial financing. While Western Europe, led by France, was the primary source, the AFOLU sector—responsible for most of Brazil's emissions—received only 11% of total funding, mostly through public multilateral sources.

The fact sheet examines how loopholes in the international tax system allow multinational corporations (MNCs) and the super-rich to avoid taxes, resulting in an estimated US$492 billion in global revenue losses for governments in 2024. It critiques the OECD/G20 Two-Pillar Solution for favoring developed nations and lacking transparency, while advocating for the 'Taxing the Super Rich' initiative and the establishment of a UN Framework Convention on International Tax Cooperation to ensure more democratic and progressive global taxation.

The report analyzes the tension between national cybersecurity measures—such as data localization, technical standards, and technology bans—and the goal of open digital trade. It finds that while cybersecurity is essential for trust in the digital economy, divergent domestic regulations create market fragmentation and trade barriers. The document evaluates the lack of specific cybersecurity rules in WTO treaties, the emergence of 'soft' aspirational provisions in Preferential Trade Agreements (PTAs) and Digital Economy Agreements (DEAs), and the significant 'cyber capacity' gap facing developing countries and Least Developed Countries (LDCs). It concludes with recommendations for evidence-based domestic frameworks and enhanced international technical assistance to bridge the digital divide.

The report examines how G20 nations, which generate approximately two-thirds of global plastic waste, can utilize extended producer responsibility (EPR) to combat marine plastic pollution. Through a scoping review of 100 sources, it identifies a disparity in effectiveness between mandatory and voluntary EPR schemes, noting that mandatory systems generally achieve higher recycling collection rates. The document provides a detailed mapping of EPR regulations across G20 members and proposes a multi-level approach combining legislative strengthening, market incentives for recycled plastics, technological innovation in ecodesign, and the formal integration of informal waste workers to prevent plastic leakage into the oceans.

The report examines how AI accelerates biological research, creating a 'dual-use dilemma' where tools for medical advancement can be repurposed for bioweapons. It analyzes the 'risk chain' of biological weapon development, the capabilities of foundation models and biological design tools (BDTs), and the geopolitical landscape involving the US, China, and Russia. The document proposes a 'preferred' 2030 scenario characterized by geopolitical stability and responsible AI development, offering specific US policy recommendations across biosecurity foundations, technical governance, and international diplomacy.

Canada is falling behind its major non-U.S. trading partners in the implementation of key climate and sustainable finance policies, particularly in mandatory climate disclosure and the development of a national climate investment taxonomy. While Canada aligns on net zero commitments and carbon pricing, the lack of progress in other areas creates economic friction and risks exposing Canadian businesses to carbon tariffs. The report argues that accelerating these policies will help Canada diversify its trade and identify new growth opportunities in a global economy increasingly aligned on climate fundamentals.

The Canadian Climate Institute finds that Canada is lagging behind its major global trading partners in the adoption of key climate and sustainable finance policies. While Canada has implemented carbon pricing and net-zero commitments, it lacks a national taxonomy, mandatory climate disclosure, and formal transition plan frameworks. This policy gap risks increasing costs for Canadian businesses and hindering their ability to compete in markets that are increasingly aligning around carbon neutrality and transparent climate risk reporting.

China is advancing a 1.3 TW pipeline of utility-scale solar and wind projects, with operating capacity reaching 1.4 TW by 2025. The country has become a global leader in offshore wind, growing its capacity to 42.7 GW by March 2025. While offshore wind is being used to decarbonize coastal industries and produce green hydrogen, the sector faces challenges from the 2021 phaseout of national subsidies and competition from ongoing coal and gas developments. The report suggests adopting hybrid auction mechanisms and centralized marine spatial planning to ensure sustainable growth.

India's export economy is increasingly vulnerable to carbon-based trade measures, with 68% of its exports going to countries committed to net zero. The report highlights that 7.5 million jobs are exposed to active Carbon Border Adjustment Mechanisms (CBAMs), and sectors like professional services are among the most carbon-intensive globally. To maintain competitiveness against rivals like Vietnam and China, the document argues India must accelerate grid decarbonisation and update its 2025 Nationally Determined Contribution.

Ember proposes a comprehensive overhaul of European grid policy, arguing that electricity grids should be treated as strategic infrastructure for economic growth. Key recommendations include establishing a 'one-stop-shop' for financing, mandating independent and integrated infrastructure planning across energy carriers, and extending national planning horizons to 20 years. The briefing also advocates for a shift toward TOTEX-based regulatory approaches to incentivise flexibility and grid-enhancing technologies (GETs), alongside the standardisation of data sharing between transmission and distribution system operators to improve visibility of distributed assets and grid capacity.

The paper examines how the geopolitical contest between the US and China over critical minerals creates a strategic window for African countries to diversify investors and build domestic green value chains.

The paper examines how trade policy can accelerate the clean energy transition by expanding access to renewable technologies. It highlights the role of the APEC List of Environmental Goods and the need to address non-tariff measures and global value chain complexities. The author advocates for a comprehensive approach that includes preferential treatment for components and services to reduce the cost and increase the efficiency of renewable energy deployment.

The letter supports the UK government's announcement of a National Methane Action Plan and argues that for the plan to demonstrate global leadership, it must set explicit 2030 targets. The authors identify three critical areas for the plan: agriculture (land use and food strategy), waste (landfill biodegradable waste elimination and methane capture), and energy (ending routine flaring and venting, implementing leak detection, and reducing emissions from imported fossil fuels).
