The document examines the greenhouse gas (GHG) footprint of palm oil, noting that emissions range from -0.3 to over 20 kgCO2e/kg CPO, with an average of approximately 6 kgCO2e/kg CPO. The primary drivers of these emissions are land-use change (LUC), particularly the conversion of tropical forests and peatlands, and the degradation of palm oil mill effluent (POME). The report highlights that emissions are highly spatially heterogeneous, with peat-based production being significantly more carbon-intensive than mineral-soil production. Mitigation strategies focus on preventing further deforestation and peatland development, managing water tables in existing peatlands, and implementing POME treatment technologies such as biogas capture and composting. The document also compares production characteristics across key regions, noting that Southeast Asia has the highest yields and production volumes, while West Africa has the lowest.

The document examines GHG emissions from the wild-caught tuna supply chain, noting that emissions typically range from 8–9 kgCO2e/kg of edible weight or tuna product. Fishing fuel use is the dominant emission source, with significant variation based on the method used: purse seining is the least intensive (1.7–4.1 kgCO2e/kg EW), while longlining and trolling can be much higher. Other contributors include packaging—specifically metal cans—and air transport, which can exceed 10 kgCO2e/kg EW. Proposed mitigation strategies include rebuilding fish stocks to improve catch-per-unit-effort, switching to low-fuel fishing methods, streamlining packaging, reducing air freight, and decreasing seafood loss and waste.

The document examines the GHG footprint of the pulp and paper industry, noting that emissions range from 14 to 75 tCO2e/t paper (excluding biogenic forestry emissions). It highlights that pulping and papermaking are energy-intensive stages that dominate the footprint, while forest management—specifically deforestation and premature harvesting—represents a significant source of emissions and a major mitigation opportunity. The report emphasizes the need for standardized GHG accounting in the sector and suggests shifting to renewable energy and sustainable forestry to reduce impacts.

The document analyzes the GHG footprint of salmon, noting that emissions are dominated by feed, with total retail emissions typically between 7 and 10 kgCO2e/kg edible weight. It highlights significant variability based on production methods, feed composition, and transport modes, while identifying land-use change in feed and air freight as primary targets for mitigation.

The report analyzes the GHG emissions of maize production, noting an average on-farm emission of 0.6 kgCO2e/kg maize. It identifies land-use change, nitrogen fertilizer application, and tillage practices as primary emission drivers. The document highlights significant regional variability, with high emissions intensity often correlating with low yields in countries like Nigeria. Proposed mitigation efforts include preventing habitat conversion, adopting no-till or strip-till farming, and optimizing nitrogen fertilizer use through nitrification inhibitors.

The report examines GHG emissions from shrimp aquaculture, noting a wide range of intensities (2 to 99 kgCO2e/kg retail product) driven by production methods, feed, and land-use change. It highlights that while intensive systems are more common and generally less GHG-intensive per unit, the conversion of mangroves for extensive ponds creates massive emissions. Key mitigation opportunities include improving feed conversion ratios (FCR), adopting conversion-free feed, and transitioning to renewable energy.

The document analyzes the GHG emissions of chicken production, noting that cradle-to-retail meat averages 7–10 kgCO2e/kg edible weight (EW). Feed, particularly land-use change (LUC) from soy and oil palm, is the primary emission driver. The report compares broiler, layer, and backyard systems, highlighting that conventional industrial farming generally has lower emissions than organic systems due to better feed conversion and bird performance. Mitigation focuses on deforestation-free feed, optimized diets, and improved manure management.

The document examines how rising temperatures and worsening air quality in Japan threaten the health and performance of Olympic and Paralympic athletes, specifically highlighting the risk of exertional heat stroke and the impact of ground-level ozone. It provides data on Tokyo's warming trend since 1964 and lists specific sports at high risk, such as the marathon and triathlon. Mitigation efforts include relocating the marathon to Sapporo, implementing the 'Tokyo 2020 Cooling Project', and athlete acclimatization.

The document details how climate change is increasing the frequency and intensity of heat waves across the United States, leading to severe health risks and societal disruptions. It highlights the vulnerability of specific populations, such as the elderly and outdoor workers, and the role of the urban heat-island effect. The text argues that stabilizing carbon emissions and adhering to the Paris Agreement can significantly reduce the projected increase in extreme temperatures and the frequency of heat waves by mid-century.

The study finds that a significant portion of diesel vehicle emissions in 11 major markets exceed certification limits, contributing to 38,000 premature deaths globally in 2015. Heavy-duty vehicles are the primary source of these excess emissions. Implementing next-generation standards beyond Euro 6/VI could avoid approximately 174,000 premature deaths by 2040.

The report analyzes the mitigation efforts of 14 priority countries and regions, highlighting a wide variation in ambition and activity. While large emitters like India and Indonesia have established legislation and quantitative targets, many other partner countries, particularly in Africa and Small Island Developing States (SIDS), prioritize adaptation due to extreme vulnerability. The analysis identifies key trends, such as the integration of low-emissions paths into economic development strategies and a heavy reliance on donor-funded projects for capacity building and MRV systems.

The agriculture sector in Pakistan contributed nearly 42 per cent of national greenhouse gas emissions in 2012. To address this, the document identifies twelve mitigation options, prioritizing five cost-effective measures: improving irrigation/water management, reducing methane from rice cultivation, implementing agroforestry, promoting better manure management, and limiting basmati rice crop burning. Together, these five priority measures are projected to reduce emissions by 11.83 MtCO2e by 2030, representing a 4.3 per cent reduction from the business-as-usual scenario.
