Science-based Target Setting for the Aviation Sector
The guidance outlines a target-setting framework for the aviation sector based on the Science Based Targets initiative's (SBTi) Sectoral Decarbonization Approach (SDA). It defines carbon intensity pathways derived from the IEA's Sustainable Development Scenario, requiring the sector to reduce average carbon intensity by approximately 35-40% between 2019 and 2035, and 65% by 2050. The framework covers Well-to-Wake (WTW) emissions, excluding non-CO2 factors due to scientific uncertainty. It provides specific instructions for aircraft operators to converge toward sector intensity levels and for aviation service users to address Scope 3 emissions, including a linear annual reduction rate of 0.4% for business air travel. The document also specifies criteria for the use of Sustainable Aviation Fuels (SAF) and explicitly excludes out-of-value-chain carbon offsets from meeting science-based reduction targets.

Final Synthesis Report
The report evaluates the impact of SO2 emissions from large solid fuel combustion installations in South Africa, primarily those operated by Eskom and Sasol. It concludes that implementing stricter emission standards is technologically feasible and economically beneficial for society due to significant reductions in public health costs, despite the high capital costs for plant operators. The panel recommends a flexible regulatory approach where emission limits are tailored to the remaining lifetime of each plant, suggesting that plants operating beyond the mid-2030s should meet stricter limits of 250 mg/Nm3 or 500 mg/Nm3, while those retiring sooner may be granted more lenient limits of 1000 mg/Nm3. The report highlights that 'expedited retirement' of older coal capacity could reduce retrofit costs by approximately 25% and minimize electricity tariff increases.

Cars, Cobalt and the Congo
The energy transition increases demand for minerals like cobalt, nickel, and lithium, which are often sourced from poorly regulated mines in a few countries, leading to human rights abuses and environmental damage. While recycling and new battery technologies could reduce this demand, current recycling rates remain low, and the industry requires more transparent, enforceable sustainability standards.

The G7 Summit and Africa: International Commitments versus Local Realities
The 47th G7 summit reaffirmed commitments to a "green revolution" and the goal of halving collective carbon emissions by 2030, while pledging to end new direct government support for international carbon-intensive fossil fuel energy. However, the document highlights a disconnect between these goals and African realities, where fossil fuels account for approximately 80% of energy supply and many states are planning coal-fired power expansions. While the G7 welcomed the commitment of up to $2 billion via Climate Investment Funds, the document notes this is insufficient compared to the $20-30 billion per year the African Development Bank estimates Africa requires for climate action until 2030. Furthermore, the $100 billion promised by developed countries since COP15 remains unrealised.

G20: Developing countries need climate finance now to halve emissions by 2030
The author asserts that the failure of developed nations to meet the 2010 commitment to mobilise $100bn per year by 2020 for climate action in developing countries erodes international trust and hinders the transition to a net-zero world. Fulfilling this commitment is presented as a catalyst to trigger large-scale private investment in low-carbon solutions and climate-resilient industries, particularly within supply chains where 65-90 per cent of company emissions originate. The text emphasizes that only 21 per cent of these funds currently support adaptation, and argues that increasing this share would protect global economic stability by building resilience in developing nations. The author calls for G20 leadership to combine this funding with mandatory climate risk disclosure and carbon pricing to support the goal of halving global emissions by 2030.

Cutting Emissions Through Fossil Fuel Subsidy Reform and Taxation
The report uses the GSI-IF model to analyze 32 countries, representing 77% of global CO2 emissions, to determine the impact of removing fossil fuel subsidies and implementing a 10% fossil energy tax by 2030. It finds that subsidy reform alone could save nearly USD 3 trillion and abate 5.4 GtCO2e, while combining reform with taxation and sustainable energy investment could increase average emission reductions from 6% to 11.8% by 2030.

Transportation Deep Decarbonization Initiative Synthesis
The report argues that deep decarbonization of transportation requires a diverse set of solutions across technology, policy, and behavior, as no single technology can address all subsectors. Key strategies include the deployment of battery electric vehicles (BEVs) for light-duty and short-haul freight, hydrogen and ammonia for heavy-duty and marine transport, and sustainable aviation fuels (SAFs) for aircraft. The authors emphasize that efficiency improvements are a critical near-term tool across all modes. A central policy recommendation is the adoption of a performance-based, adaptive framework, specifically a Low Carbon Fuel Standard (LCFS) transitioning to a Zero-Carbon Fuel Standard (ZCFS) by 2050, to allow various fuels and vehicles to compete while reducing overall carbon intensity. The report also highlights the daunting nature of infrastructure transitions and the uncertainty of consumer behavior and automated vehicle impacts.

COMMENTS ON POTENTIAL IMPACTS OF PROPOSED NEW COAL GENERATION UNDER THE SOUTH AFRICA 2019 INTEGRATED RESOURCE PLAN
The report argues that the 2019 IRP's goal of adding 1500 MW of new coal generation is technically and environmentally problematic. It concludes that 'clean coal' is a myth, as even high-efficiency, low-emission (HELE) technologies cannot eliminate significant air pollution and greenhouse gas emissions. The author finds that advanced ultra-supercritical plants and carbon capture technologies are currently unproven or cost-prohibitive at scale, making them unlikely to be implemented. Furthermore, the report asserts that the 2023 timeline for the first 750 MW is unrealistic and that new plants would inevitably cause harm to human and environmental health through emissions of toxic organic compounds, trace metals, and acid gases, as well as impacts from the broader coal supply chain.

Cutting Emissions Through Fossil Fuel Subsidy Reform and Taxation
The report finds that the complete removal of fossil fuel consumption subsidies across 32 modelled countries could reduce greenhouse gas emissions by an average of 6.09% by 2030. When combined with a 'subsidy swap' (reinvesting savings into energy efficiency and renewables) and a 10% energy tax, the average national emission reduction increases to 11.84%. The analysis highlights that while some countries like Venezuela see reductions over 30%, G20 nations provide the largest absolute reductions due to their economic scale. Financially, fossil fuel subsidy reform (FFSR) alone could generate USD 2.99 trillion in cumulative savings by 2030, offering a cost-effective mechanism for a 'green recovery' from the COVID-19 pandemic.

Driving Demand: Assessing the impacts and opportunities of the electric vehicle revolution on cobalt and lithium raw material production and trade
The report examines the global market for lithium-ion batteries and the critical role of lithium and cobalt. It uses Chile and the Democratic Republic of the Congo (DRC) as case studies to illustrate how developing countries can capture value from the electric vehicle (EV) boom while managing risks such as price volatility, technological shifts toward cobalt-free batteries, and social or environmental degradation. The document argues that while lithium demand remains stable, cobalt faces higher uncertainty, suggesting that producer countries should diversify into mining-related services to avoid stranded assets.

Measuring the Wealth of Nations: A review
The report argues that GDP is an insufficient measure of national well-being because it ignores the depletion of assets and favors short-term gains. It advocates for 'comprehensive wealth' measurement, which tracks five capital types: produced, financial, natural, human, and social capital. The document reviews global initiatives from organizations like the World Bank, UNEP, and OECD, noting that while human and produced capital have generally grown, natural capital is declining globally, particularly in developing countries. It concludes that comprehensive wealth accounts are essential for building resilience to climate change and achieving the UN 2030 Agenda's Sustainable Development Goals, specifically SDG 17.

Assessment of the NGFS’ second set of climate scenarios
The report argues that the NGFS's second set of 1.5°C scenarios are not aligned with the Paris Agreement and are unsustainable due to an over-reliance on fossil fuels, biomass, and carbon dioxide removal (CDR). It finds that these scenarios fail to account for the need to end fossil fuel expansion and rely on unproven technologies like Carbon Capture and Storage (CCS) to justify slower phase-outs of oil, gas, and coal.

Japan Is Not an Obstacle to a US “No-First-Use” Policy
The document contends that US concerns regarding a nuclear-armed Japan are unfounded and should not prevent President Biden from declaring a no-first-use policy. It bases this on two secret government inquiries (1970 and 1995) that rejected the nuclear option, overwhelming public opposition to nuclear weapons in Japan, and the fact that a small minority of conservative officials lack the political agency to pursue such a program. The report asserts that a no-first-use declaration would not undermine the US nuclear umbrella's deterrent function for Japan.

Chinese Infrastructure Provision to the Global South and the Setting of Rail Standards
The document analyzes the impact of China's Belt and Road Initiative (BRI) and the Trans-Asian Railway (TAR) Network on rail standardization, specifically the shift toward high-speed, standard-gauge rail. Using examples from Malaysia, Cambodia, and Lao PDR, it highlights that while technical standards are a concern, the primary challenges are project costs, debt sustainability, and the need for cross-border trade facilitation. The author recommends that African nations prioritize integrated regional planning, transparency in procurement, and low-carbon transport strategies to maximize the development impacts of rail expansion.

Global Climate Action from Cities, Regions and Businesses 2021
The report finds that while the number of non-state and subnational actors setting climate targets is growing, there is limited evidence that this ambition is translating into realized impacts. Full implementation of individual targets could reduce 2030 emissions by 2.0 to 2.5 GtCO2e/year, while international cooperative initiatives' goals could lead to a reduction of 16 GtCO2e/year. However, progress is uneven, with only half of city governments and 80% of companies meeting their 2020 targets.

Japanese banks still have to catch up with their European peers on coal
Reclaim Finance argues that Japan's three megabanks (Mizuho, MUFG, and SMBC) maintain policies that allow continued support for the coal industry. While the banks have updated policies to restrict direct project financing for new coal plants 'in principle', these policies contain exceptions and do not apply to general corporate financing. Between October 2018 and October 2020, these banks provided $39bn, $36bn, and $32bn respectively to companies on the Global Coal Exit List. The document contrasts this with European peers like Crédit Agricole and notes increasing shareholder and activist pressure on the Japanese institutions to align with the Paris Agreement.
