The analysis finds a modest positive correlation between the proportion of outdoor workers and worry about extreme heat at the county level, though this relationship varies by region. While the South and West show positive correlations, the Midwest and Northeast show negative correlations. At the state level, a stronger positive correlation exists. The document also notes a gap between heat worry and the implementation of worker protections, highlighting that some high-worry states like Texas and Florida have blocked local heat safety standards, while California's 2005 standards are linked to a 30% reduction in heat-related injuries.

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 analyzes the systemic difficulties G20 nations face in transitioning from fossil fuels, citing economic dependencies, infrastructure lock-in, and social risks to workers. It notes a failure to meet 2009 G20 commitments to phase out subsidies, with G7 and developing nations spending hundreds of billions in 2023. The text emphasizes South Africa's 2025 G20 presidency as an opportunity to champion a people-centered approach involving green industrial hubs and socio-economic safeguards for coal-dependent regions.

The building sector accounts for 18% of Canada's GHG emissions, necessitating a focus on upgrading approximately 11 million existing residential buildings. Achieving net-zero requires a balance of deep energy retrofits (DERs), fuel-switching to heat pumps, and expanding clean electricity. An annual investment of CAD 10-15 billion until 2040 could generate 200,000 jobs and CAD 48 billion in economic development. The document recommends strengthening building codes, implementing PACE financing, and integrating energy efficiency with affordable housing policies.

The document outlines a structured approach to NAP progress reporting, categorized into three primary objectives: tracking activities, evaluating performance, and learning/communication. It provides a detailed toolkit of 17 specific methods—ranging from simple checklists and traffic-light systems to complex indicator tracking and digital platforms—supported by real-world examples from countries such as Saint Lucia, Burkina Faso, and Finland. The guide emphasizes an iterative 'learning by doing' approach, urging countries to start simply and integrate gender equality and social inclusion (GESI) into their reporting frameworks.

The document outlines a framework for reporting progress on National Adaptation Plans (NAPs), categorizing methods into three primary objectives: monitoring status, evaluating performance, and learning/communication. It provides step-by-step instructions for 17 different methods, ranging from low-effort checklists to high-effort digital platforms and indicator tracking. The guide emphasizes a 'learn-by-doing' approach, encouraging countries to start with simple methods and increase complexity as capacities grow, while ensuring the integration of gender equality and social inclusion (GESI).

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.

Two years after the COP28 agreement to triple global renewable capacity by 2030, national targets remain largely stagnant. As of July 2025, the global sum of national targets has increased by only 2% since COP28, reaching 7.4 TW, which is significantly below the 11 TW required to meet the tripling goal. Only 22 countries have updated their targets, with the majority of these being EU member states revising plans through the National Energy and Climate Plan (NECP) process. Most non-EU updates occurred through routine planning cycles rather than as a direct response to COP pledges. Major electricity markets, including the US, Russia, and Canada, have either not set explicit targets or are unlikely to update them in 2025.

The report examines economic and societal trends affecting Germany's material prosperity and climate protection, utilizing mini-scenarios to 2040 to identify necessary actions for policymakers and experts.

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.

Susanne Riegraf, Deputy of the Federal Government Commissioner for Disarmament and Arms Control, delivered a keynote speech at the Berlin Biosecurity Dialogue on June 19, 2025. She highlighted the increasing risk of biological weapons due to the convergence of biotechnology, AI, and quantum computing, noting that AI-modified proteins can evade conventional detection methods. Riegraf discussed the limitations of the 1972 Biological Weapons Convention (BWC), which lacks a verification regime, and the need for NATO allies to enhance collective biodefense and early-warning systems. She also detailed Germany's interagency coordination challenges and its international support efforts through the German Biosecurity Programme and the Global Health Protection Programme.

Phaesun GmbH, in collaboration with Solar Cooling Engineering GmbH and Efficiency for Access, installed a solar-powered cold room in Homabay, Kenya, between April and September 2024. The facility, operated by WeHub Victoria Limited, uses SelfChill technology and thermal energy storage to chill up to 500 kg of agricultural products daily to 10°C. Built with wood and straw to minimize costs and carbon footprint, the project was funded by the Siemens initiative Cents4Sense, Siemens Stiftung, and the Efficiency for Access Research and Development Fund, keeping total investment costs under 30,000 EUR.

Deep-sea mining targets critical minerals like cobalt and nickel from polymetallic nodules, sulfides, and crusts, primarily in international waters such as the Clarion-Clipperton Zone. While proponents argue it can meet surging demand for the energy transition and avoid some terrestrial mining harms, the practice faces significant opposition due to risks of species extinction, disruption of the ocean's carbon sink, and threats to food security in small island states. Commercial exploitation remains stalled as the International Seabed Authority (ISA) has failed to reach a consensus on regulations as of July 2025, though some companies may attempt to bypass this via U.S. domestic law. Alternatives such as scaling up recycling and shifting to LFP or sodium-ion batteries could reduce the necessity of seabed extraction.

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.

Global Witness reports that 92% of surveyed environmental defenders have suffered online abuse, with Meta-owned platforms (Facebook, WhatsApp, Instagram) being the most frequent sites of harassment. The report highlights a direct link between digital attacks and offline violence, noting that 75% of those harmed offline believe online abuse contributed to it. It criticizes social media algorithms for promoting polarization and argues that inadequate moderation resources, particularly in Africa and Asia, leave defenders vulnerable to doxxing, cyberattacks, and criminalization. The document concludes that these digital threats create a chilling effect on the climate movement, leading to productivity loss and, in some cases, the cessation of activism.

The document warns that reforming the MSR2 before the ETS2 launches in 2027 could lead to an oversupply of allowances, weakening the price signal and jeopardizing the EU's 2030 climate target of a 42% reduction in covered emissions. It argues that high prices should be managed through 'complementary measures'—such as CO2 standards for vehicles and boiler phase-outs—and the strategic use of the Social Climate Fund and €300 billion in ETS2 revenue. The authors contend that existing safeguards, including a 'soft price cap' of approximately €55 per tonne and the early auctioning of 30% more allowances, are sufficient for the initial phase. They caution that any increase in allowance supply must be 'cap neutral' to avoid exceeding the carbon budget.

The document details the significant health and economic burdens of meat consumption and livestock production, linking red and processed meats to millions of deaths from non-communicable diseases and highlighting the risks of zoonotic diseases and antimicrobial resistance. It quantifies global healthcare costs and suggests that shifting toward plant-based diets could save trillions of dollars and millions of lives.

In June 2025, solar power became the largest source of electricity in the EU, generating 22.1% of the total supply. This milestone coincided with record-high wind generation for May and June and a record low for coal's share of electricity. However, the first half of 2025 saw an overall increase in fossil fuel generation, driven by higher gas use and lower hydropower output due to drought.

The report contends that Canadian LNG projects are high-risk investments due to capital intensity, market volatility, and declining global demand. It highlights that importers in Europe and Asia are shifting toward renewables to avoid the price spikes and supply shocks associated with LNG. The authors argue that new LNG infrastructure threatens to become stranded assets, potentially requiring further taxpayer subsidies, while simultaneously increasing global greenhouse gas emissions and delaying the energy transition.
