The report analyzes seven categories of enclosure-based and open measurement methods for greenhouse gas emissions in sanitation systems. It finds that while enclosure-based methods like flux chambers are widely used, they are limited by scale. Emerging optical and remote sensing methods offer broader coverage but are constrained by high costs. The document highlights a critical lack of empirical data for non-sewered sanitation in low- and middle-income countries and advocates for standardized, affordable methodologies and increased collaboration to improve national greenhouse gas inventories.

Between 2021 and 2023, commercial banks in G7 countries provided US$101 billion to the coal industry, with American and Japanese banks contributing over US$73 billion. The report highlights that this financing exceeds the G7-led pledges for Just Energy Transition Partnerships (JETPs) and calls for stricter capital requirements and prohibitions to ensure a phase-out aligned with 1.5°C goals.

Between 2021 and 2023, commercial banks from G7 countries provided $101 billion to the coal industry, with US and Japanese banks leading the funding. The report highlights that this financing far exceeds the G7-led funding promised for Just Energy Transition Partnerships (JETPs) in developing nations. It criticizes the G7's goal of phasing out coal by the first half of the 2030s as insufficient to meet the 1.5°C warming limit and calls for strict capital requirements and bans on coal developers.

The document assesses the viability of Canada's planned LNG expansion, concluding that it is incompatible with 1.5°C global warming targets and economically precarious. It highlights that new facilities would increase domestic emissions and divert clean energy resources. Economically, the brief warns of a global supply glut by 2030, with Canadian projects struggling to compete against lower-cost producers in Qatar and the United States, thereby risking significant losses for taxpayers and investors.

The report details a record-breaking Q1 2024 for aligned GSS+ debt, with USD 272.7bn added. Green bonds dominated the market, while Europe remained the primary regional source. The report also highlights the growth of sovereign GSS+ issuance, the emergence of nuclear energy in green bond frameworks in North America, and the evolving alignment of sustainability-linked bonds (SLBs) with Climate Bonds' methodology.

The report finds that while burning hydrogen in power plants is technically feasible, it is likely not a cost-effective solution for bulk power production or load following. The authors highlight significant inefficiencies, such as a 24% round-trip efficiency for electrolytic hydrogen, and high costs for necessary geological storage and transport infrastructure. Lifecycle emissions reductions for hydrogen derived from natural gas with carbon capture are limited (averaging 50%) due to upstream methane leaks. The report concludes that clean hydrogen production should be prioritized for heavy industry and transportation rather than the power sector, where clean firm generation (e.g., nuclear, geothermal) or other storage options (e.g., pumped storage hydropower) are generally more economical.

In 2023, Hong Kong's aligned GSS+ debt volume grew by 236% to USD 18.2 billion, driven primarily by the HKSAR Government's green bond issuance. The market is characterized by a strong preference for green-themed debt, with low-carbon buildings and land use as the primary use-of-proceeds categories. While the HKSAR Government dominates the local market, the Hong Kong Stock Exchange remains a key hub for offshore Chinese green bonds. The report also highlights the emergence of transition finance frameworks in mainland China and the introduction of the Hong Kong Taxonomy for Sustainable Finance to improve interoperability with international standards.

The report argues that fiscal policies—including roadmaps, tax incentives, guarantees, and subsidies—are essential to bridge the net-zero investment gap in the ASEAN+3 region. It identifies critical barriers such as a lack of suitable project pipelines, regulatory uncertainty, and the predominance of MSMEs. The document recommends a holistic approach combining these fiscal tools with non-fiscal policies like green taxonomies and mandatory climate disclosures to steer the financial sector toward sustainable development goals.

The report argues that labelled transition finance is currently stalled by 'transition-washing'—where finance is provided to entities without a credible plan to reach net zero. It identifies root causes such as a lack of scientifically robust, geography-specific emissions pathways and the prevalence of non-binding voluntary standards. Using sustainability-linked bonds (SLBs) and Japanese transition-labelled bonds as case studies, the author highlights issues like unambitious targets, immaterial penalties, and reliance on non-credible technologies like ammonia co-firing. To address this, the report recommends six guardrails: preparing national Paris-aligned pathways, establishing robust classification standards, building external verification capacity, implementing mandatory regulatory thresholds for protected labels, empowering regulators to penalise transition-washing, and enacting systemic reforms such as mandating transition plans for large firms.

The document assesses the viability of Canadian LNG expansion, concluding that it is incompatible with climate goals and economically precarious. It highlights that new facilities would increase domestic emissions and potentially strand assets due to a projected global supply glut and declining demand in advanced economies. The brief specifically notes that Canadian projects face higher production costs than competitors in Qatar and the United States, making them reliant on substantial public subsidies. It recommends a shift in investment toward green industries to avoid economic shocks and environmental damage.

The document analyzes India's high import dependence on copper and the global supply risks—including geopolitical instability in producer nations and declining ore grades—that threaten its economic and energy goals. It proposes a four-pronged strategy: diversifying primary supply through strategic partnerships, reforming trade duties to encourage domestic value addition, providing production-linked incentives for the smelting and fabrication industry, and rationalizing the GST on copper scrap to formalize the recycling sector.

The 2023 assessment by WWF reveals that while 31% of the 42 analyzed asset managers showed minor or moderate improvements in managing nature and biodiversity risks, specific action regarding the seafood sector remains low. Only one asset manager has publicly disclosed seafood-specific E&S expectations for investee companies. The report highlights significant gaps in expectations regarding sustainability certifications and supply chain traceability. It notes a positive trend in Japanese asset managers' progress, likely driven by national biodiversity and IUU fishing regulations. WWF recommends that asset managers formalize biodiversity risk statements into actionable policies, set time-bound sustainability targets, and develop targeted 'blue' financial products to support a sustainable blue economy.

The document examines the three mechanisms of Article 6 (A6.2, A6.4, and A6.8) of the Paris Agreement, highlighting the tension between rapid operationalisation and the need for high-integrity standards to prevent greenwashing and human rights abuses. It details the specific sticking points for COP29, including transparency in bilateral trading (A6.2), the role of the Supervisory Body in the global market (A6.4), and the potential for non-market approaches (A6.8) to provide alternative climate finance. The briefing also analyzes the influence of these UN rules on the voluntary carbon market (VCM) and the controversies surrounding REDD+ credits and land-use offsets.

The 2024 Banking on Climate Chaos report reveals that the 60 largest global banks committed $705.8 billion to fossil fuel companies in 2023, with $347.5 billion directed toward companies with active expansion plans. JPMorgan Chase is identified as the worst financier of fossil fuels, while Japanese megabanks like Mizuho and MUFG are prominent in methane gas (LNG) financing. The report highlights significant policy gaps, noting that many banks use intensity-based metrics rather than absolute emissions targets and that some North American banks have rolled back previous exclusions for coal and Arctic oil and gas. It argues that current 'net zero' targets often serve as loopholes for continued investment in fossil fuel infrastructure, particularly in Southeast Asia.

The petrochemical industry is a growing driver of global oil demand and greenhouse gas emissions, with nitrogen fertilisers and plastics as primary contributors. Rapid capacity expansion, particularly in China, is projected to increase emissions beyond 1.5°C warming limits. While technical solutions and recycling are proposed, the low cost of virgin plastics and the limitations of 'downcycling' hinder progress, suggesting that policy should prioritise reuse and the reduction of single-use materials over simple substitution or recycling.

In 2023, solar and wind power continued to grow, with solar producing a record 5.5% of global electricity and wind reaching 7.8%. China was the primary driver for both, accounting for 51% of solar growth and 60% of wind additions. Conversely, coal generation reached a record high of 10,434 TWh (35% of the global mix), largely due to droughts in China reducing hydropower output, which fell by a record 88 TWh. Fossil gas remained the second-largest source at 23%, with growth driven by the US. Nuclear generation saw a slight rebound to 9.1% of the mix, while bioenergy reached a record 697 TWh (2.4%). The report notes that while solar and wind are on a positive trajectory, coal and gas must decline sharply, and nuclear and hydro must accelerate growth to meet IEA Net Zero Emissions targets by 2030.

In 2023, the world's top six electricity sector emitters—China, the US, India, the EU, Russia, and Japan—accounted for approximately 72% of global emissions from this sector. China remains the largest emitter, though it leads the world in wind and solar growth. The US and EU have seen long-term emissions declines driven by the replacement of coal with gas and renewables. India's emissions continue to rise as demand growth outpaces clean energy additions. Russia's electricity mix remains largely unchanged over two decades, while Japan is seeing a recovery in nuclear generation and a significant increase in solar share, despite very low wind deployment.

In 2023, the share of renewables in the global electricity mix exceeded 30% for the first time, driven by record solar and wind generation. Despite this, total power sector emissions reached a record high of 14,153 million tonnes of CO2 because clean growth could not fully meet rising demand and was hampered by a record fall in hydropower. While carbon intensity hit a record low of 480 gCO2/kWh, fossil generation increased by 135 TWh, primarily in emerging economies like China and India where droughts reduced hydro output.

The report identifies 2023 as the likely peak for global power sector emissions, forecasting a decline in 2024 driven by record solar and wind additions. While electricity demand is expected to rise due to electrification, data centres, and air conditioning, the growth of clean energy is projected to outpace this demand. The document highlights that tripling renewable capacity by 2030 could halve power sector emissions. It also provides case studies of China, Brazil, and the Netherlands to demonstrate how high-level ambition, incentive mechanisms, and the removal of technical barriers can accelerate the transition regardless of geographic or economic starting points.

The document assesses the current state of bioeconomy strategies across G20 nations, identifying three primary thematic axes: biotechnology (R&D&I), bioresources (sustainable use of biodiversity), and bio-ecology (sustainable development). It highlights the significant economic potential of the sector, citing estimates that its value could reach US$30 trillion by 2050. The report emphasizes the necessity of integrating indigenous and local knowledge, ensuring social equity, and aligning bioeconomy growth with biodiversity conservation and climate action. It further examines policy enablers such as Green Public Procurement and carbon pricing, and discusses financing mechanisms including nature markets and sustainability-linked bonds. The report concludes by proposing five key themes for the G20 Initiative on Bioeconomy's program of work: integration into growth plans, livelihoods and equity, enabling finance, facilitating biotrade, and measurement methodologies.
