The Clean Air Task Force (CATF) opposes New York City's proposed biodiesel heating fuel mandate, arguing that increasing demand for vegetable oil-derived biodiesel drives the expansion of palm oil production. This expansion leads to the destruction of tropical peatland forests, particularly in Indonesia and Malaysia, resulting in significant carbon dioxide releases and public health crises. CATF contends that even soybean-based biodiesel contributes to these impacts through global market fungibility and that current USEPA lifecycle analyses underestimate these greenhouse gas emissions.

The document examines the limited global carbon budget available to restrict warming to 1.5°C and the resulting necessity for Australia to undergo a rapid energy transformation. It argues that current national pledges under the Paris Agreement are insufficient and that relying on future 'negative emissions' technologies is risky. For Australia, a 'fair share' of the carbon budget would be exhausted in less than six years at current emission levels, necessitating a shift away from fossil fuel extraction and exports.

The study identifies significant current potential for cultivating Acrocomia aculeata in Latin America, particularly in Central America, the Caribbean, northern Colombia, Venezuela, southern Brazil, and eastern Paraguay. However, it warns that many suitable areas are already used for agriculture or have high conservation value, and that under the IPCC A2A 'business as usual' scenario, most suitable growing areas could severely decline or disappear by 2080.

The paper evaluates the feasibility of the International Civil Aviation Organization's (ICAO) goal for carbon-neutral growth from 2020 onward. It finds that high-integrity carbon offsets and sustainable biofuels can provide a significant portion of the required emission reductions, suggesting that ICAO can maintain high environmental and sustainable development standards without compromising its goals.

The report evaluates the feasibility of ICAO's 'carbon neutral' goal for international aviation growth from 2020 onward. It finds that a selective approach to carbon offsets—focusing on high-integrity projects like methane avoidance—could meet 70–90% of projected demand (3.3–4.5 Gt CO2e) between 2020 and 2035. Including medium-confidence projects would further increase supply to 5.1 Gt CO2e, with REDD+ potentially adding 2.4 Gt CO2e. Alternative biofuels offer lower cumulative reductions (0.1–0.3 Gt CO2e) and face significant challenges regarding land use change and sustainable development, particularly with oilseed crops.

The Living Amazon Report 2016 provides a comprehensive overview of the Amazon biome, highlighting its immense biodiversity and critical role in global climate and hydrological regulation. It identifies primary threats including large-scale agriculture, cattle ranching, hydropower dams, and extractive industries, while advocating for a coordinated, biome-wide conservation approach. The report emphasizes the importance of protected areas and indigenous territories, which currently cover over 50% of the biome, and recommends strategies for enhancing climate resilience and securing water connectivity.

The World Resources Institute (WRI) argues that a CMU study underestimated the environmental benefits of low-meat diets because it failed to account for land-use change, grouped beef with more efficient meats like pork, and modeled 'healthy' scenarios that actually increased total animal-based food intake. WRI asserts that shifting to realistic vegetarian diets can reduce per capita land use and greenhouse gas emissions by approximately half.

The ADVANCE Approach is a partnership between the World Wildlife Fund (WWF) and the Columbia University Center for Climate Systems Research (CCSR) designed to move away from short-term consultant-based climate science engagement. It employs a seven-step co-generation process—analyzing context, developing learning questions, gathering data, obtaining feedback, revising information, providing integration guidance, and evaluating outcomes—to ensure climate risk data is fit-for-purpose and usable for local decision-makers. The approach focuses on identifying specific climate thresholds and variables relevant to stakeholders, such as maximum temperature in tropical regions or upland precipitation for mangrove conservation, and builds local capacity to interpret and apply this information to build resilience.

The document argues that global diets are converging toward resource-intensive Western styles, which threatens environmental sustainability and human health. Using the GlobAgri model, the authors demonstrate that reducing calorie and protein overconsumption among wealthy populations can significantly spare agricultural land and reduce greenhouse gas emissions. The paper introduces the 'Shift Wheel' framework to help the food industry implement these dietary changes through behavioral and marketing strategies.

The report by Eyes on the Forest (EoF) reveals systemic illegality in the Indonesian palm oil sector, specifically in Riau and Sumatra. Through chain-of-custody tracking, EoF demonstrated that FFB illegally grown in Tesso Nilo National Park and the ex Dalek area reached CPO mills and refineries operated by global giants including Wilmar, RGE (Asian Agri and Apical), Golden Agri-Resources (GAR), and Musim Mas. The findings suggest that current traceability efforts focusing on the mill level are insufficient to prevent the seepage of illegal products, as illegal FFB can travel up to 128 km to reach mills. The report argues that the high prevalence of illegal plantations—estimated by the Indonesian government at 50% in Riau—makes almost all CPO mills in the region high-risk, necessitating a shift toward full traceability to the plantation level.

The study examines how fragmented climate policies, where some regions implement carbon taxes while others do not, lead to 'carbon leakage'—the relocation of emissions to non-participating regions. It distinguishes between industrial carbon leakage (ICL), driven by fossil fuel price changes, and terrestrial carbon leakage (TCL), driven by land-use changes. The findings indicate that TCL is the dominant form of leakage until 2050, primarily due to deforestation in non-participating regions as food and bioenergy production shift away from participating areas. The research concludes that the total leakage rate decreases as the size of the climate coalition increases, but even the most inclusive fragmented scenarios fail to limit global temperature rise to below 2°C by 2100.

The study finds that ethanol produced from cane molasses in Indonesia results in a 67% reduction in greenhouse gas emissions compared to gasoline, with emissions estimated at 29 gCO2e per MJ. While the Net Energy Value is -7 MJ/l, the Net Renewable Energy Value is 17.7 MJ/l and the energy yield ratio is 6.1. The analysis indicates that results are highly sensitive to molasses price, ethanol yield, and sugarcane yield, and suggests that energy and environmental gains can be improved through biogas recovery from wastewater and surplus bioelectricity generation via efficient cogeneration using sugarcane biomass residues.

The report examines the relationship between human migration and ecosystem degradation in the Great Lakes Region of Africa, focusing on case studies in Uganda, Ethiopia, and the Democratic Republic of Congo. It argues that while migration is not the primary cause of environmental pressure, it acts as an exacerbating factor that increases habitat destruction and unsustainable resource use. The document provides a framework for conservationists to integrate migration trends into land-use planning and natural resource governance.

The document argues that relying on future negative emissions to offset current insufficient climate action is a high-risk strategy. It identifies three primary risks: technological and biophysical infeasibility, unacceptable social and ecological impacts, and the potential for these measures to be less effective than expected due to reversals or irreversible climate tipping points. The authors conclude that while some land-based sequestration is possible, it cannot reach the scales often assumed in climate models without severe trade-offs.

The report examines 13 watershed investment programs in the U.S., focusing on how natural infrastructure—specifically forests—can be used to protect drinking water quality and quantity. It provides a framework for program development across three phases: building momentum, designing the program, and implementing the action plan. Key findings emphasize the importance of collaborative partnerships, scientifically informed planning, and diverse financing mechanisms, such as municipal bonds and water rate surcharges, to overcome barriers like insufficient funding and lack of outcome data.

The 2016 Orinoco Basin Health Report evaluates the Colombian section of the Orinoco River basin, assigning an overall health score of 3.2 (moderately good) based on 11 indicators. The analysis reveals a clear west-to-east gradient: western sub-basins like Alto Meta (1.9) suffer from high degradation due to agro-industrial expansion and oil and gas extraction, while eastern sub-basins like Matavén (4.4) remain more intact. Key threats across the region include deforestation, illegal mining, and unsustainable land-use changes. The report emphasizes critical data gaps in water quality monitoring and biodiversity inventories and aligns its findings with the UN 2030 Agenda for Sustainable Development.

The UNEP/SETAC Life Cycle Initiative provides global guidance on harmonizing LCIA indicators to improve the comparability and accuracy of environmental assessments. The document recommends specific metrics for climate change (GWP100 and GTP100), human health impacts from PM2.5, water scarcity (AWARE approach), and biodiversity loss from land use, while proposing an updated LCIA framework that distinguishes between intrinsic, instrumental, and cultural values.

WWF and the University of Maryland’s Center for Environmental Science (UMCES) are implementing a standardized process to create freshwater basin report cards. These tools synthesize complex data into accessible grades to empower stakeholders and improve management. The process involves six steps: stakeholder engagement, indicator selection, threshold definition, scoring, communication, and score improvement. A 2016 case study of Colombia’s Orinoco River Basin, which received a B-minus grade, demonstrates the model's application in addressing threats like land-use change and extractive industries.

The Plowprint report by WWF International tracks the gross conversion of intact grasslands to cropland in the US and Canada from 2008/2009 to 2015. Unlike net conversion studies, the Plowprint counts land as converted even if it later reverts to grass, arguing that the initial plow-up causes significant, long-term ecological loss. The analysis uses federal satellite-derived data to identify conversion hotspots and emphasizes the loss of ecosystem services such as carbon sequestration and water filtration. While noting that nearly half of the Plowprint area had reverted to perennial cover by 2015, WWF maintains that such restoration may not fully recover biological diversity or soil capacity. The document also outlines WWF's broader efforts to reduce grassland and forest conversion globally, specifically targeting soy, beef, and palm oil supply chains in Latin America and Southeast Asia.

The document refutes claims that WRI miscalculated biomass energy potentials and solar efficiency comparisons, arguing that solar PV is significantly more land-efficient than bioenergy. It challenges the existence of abundant 'marginal land' for biofuels, asserting that such lands often provide critical carbon storage or face economic and legal constraints. WRI further argues that bioenergy does not inherently reduce greenhouse gas emissions unless it drives yield increases beyond what is already required to feed the global population, and that it does not reliably reduce poverty or increase food availability.
