The report details a co-creation process between Kalmar municipality and the Stockholm Environment Institute to align a new mobility strategy with the Agenda 2030 goals. The strategy aims for a transport mode split of 60% walking, cycling, and public transport and 40% cars by 2035. Analysis indicates strong positive impacts on public health and sustainable cities, though risks include social polarization among car-dependent groups and potential conflicts over land use for biodiversity. Key recommendations include implementing '15-minute city' planning, enhancing fossil-free maritime transport, and using life-cycle analyses in procurement.

The report outlines the activities of the St. Louis Controlled Environment Agriculture (STLCEA) Coalition, which selected AeroFarms to develop a large-scale commercial vertical farm and community-based farms in the St. Louis region. It evaluates various energy strategies to reduce the high carbon footprint of indoor farming, including the use of stranded assets like river cooling, underwater turbines, and waste-to-energy systems. Additionally, the document describes the establishment of a Center of Excellence (CoE) led by The Yield Lab Institute to foster knowledge sharing and technological innovation in the fragmented CEA industry while addressing food insecurity and racial inequality in north St. Louis.

The document argues that the DOE's proposed 4 kgCO2e/kgH2 standard is too weak and should be lowered to 1 kgCO2e/kgH2 to prioritize truly zero-emission hydrogen. It criticizes the GREET model for underestimating methane leakage and grid emissions, warns against the safety and environmental risks of carbon capture and storage (CCS), and demands that the hydrogen hub program incorporate strict environmental justice protections and community engagement.

The study compares two scenarios for managing dredged sediments in Malmfjärd Bay: landfilling and soil conditioning. Soil conditioning was found to be the most sustainable and economically viable option due to reduced fertilizer consumption, although it presents risks of eutrophication and toxicity that may require pre-treatment. Landfilling's primary impact is the emission of greenhouse gases during facility operation.

The document analyzes GHG emissions from coffee production, ranging from 3 to over 40 kgCO2e/kg roast coffee, with an average of approximately 20 kgCO2e/kg. It identifies land-use change, fertilizer use, and wet-processing effluent as the primary emission drivers. The briefing highlights that while polyculture systems sequester more carbon than monocultures, the overall footprint is highly variable based on location and practice. Key mitigation strategies include preventing deforestation, treating processing effluent, and improving fertilizer management, though implementation is challenged by the prevalence of smallholder farming.

The document examines the GHG footprints of soy production, emphasizing that land-use change (LUC) is the primary driver of emissions. It details emissions from farm-gate activities, processing, and transport, while comparing production systems and regional impacts, particularly in South America. Mitigation priorities focus on preventing deforestation and improving tillage and fertilizer practices.

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 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 outlines a step-by-step process for assessing organisational GHG footprints, based on international standards like the GHG Protocol and ISO 14064. It defines three scopes of emissions: Scope 1 (direct), Scope 2 (indirect energy), and Scope 3 (other indirect value chain emissions). A central feature is the provision of a database of emission factors specifically developed for the Estonian context, covering energy production, vehicle fuels, and waste management. The guide also discusses the relationship between GHG accounting and regulatory frameworks such as the EU Emissions Trading System (EU ETS), the Corporate Sustainability Reporting Directive (CSRD), and the EMAS environmental management system.

Earthjustice and several partner organizations request that the BLM defer approval of oil and gas drilling permits in Kern County, California. They argue the BLM has violated the National Environmental Policy Act (NEPA) and other laws by failing to provide public comment periods on Environmental Assessments (EAs). The statement highlights severe public health risks to environmental justice communities in Kern County, including high rates of asthma and cancer, and argues that the BLM's air emissions estimates are unrealistically low and violate the Clean Air Act. It further demands a 'hard look' at water scarcity, groundwater contamination from unlined waste pits, and the climate impacts of carbon-intensive California crude. Finally, it asserts that new drilling threatens the critically imperiled Temblor legless lizard.

The European Union's projected hydrogen demand is expected to rise from 8.3 Mtpy to over 60 Mtpy by 2050, with the World Energy Council estimating that 50% of this demand must be met through imports from regions such as the Middle East, North Africa, and the U.S. To ensure these imports are climate-beneficial, the Clean Air Task Force (CATF) advocates for a certification system that measures greenhouse gas (GHG) emissions across the entire value chain—including production, storage, transport, and conversion—rather than focusing solely on production facilities. The document highlights a regulatory gap, noting that the Gas Package's delegated act for GHG emissions methodology is not planned until 31 December 2024, which lags behind current market activities and Memoranda of Understanding. CATF recommends that the EU adopt a technology-inclusive approach covering renewable and low-carbon hydrogen (including blue hydrogen), incorporate stringent methane leakage criteria, and align its methodology with the Methane Regulation's monitoring, reporting, and verification requirements by 2027.

The European Union faces a significant hydrogen supply gap, with demand projected to rise from 8.3 million tonnes per year to over 60 million tonnes by 2050, necessitating imports from regions such as the Middle East, North Africa, and the USA. The Clean Air Task Force argues that current certification efforts are often voluntary or too narrow, focusing only on production plants rather than the full value chain. To avoid market uncertainty and investment risks, the document recommends that the EU's 'Gas Package' and subsequent delegated acts establish a technology-neutral certification methodology. This methodology must employ a full life-cycle analysis (LCA) that includes upstream methane leaks, transport, storage, and distribution to ensure genuine greenhouse gas reductions.

The document analyzes green public procurement (GPP) in Sweden and the Netherlands, focusing on the high-emission road transport and construction sectors. While both countries utilize GPP, the Netherlands employs more centralized, nationally developed tools and databases, whereas Sweden's approach is more decentralized. Key barriers in both nations include a lack of human resources, insufficient contract follow-up, and a need for better public-private dialogue. The briefing suggests that while GPP is widely practiced, more systematic implementation and standardized data reporting are required to meet national and EU climate objectives.

An executive summary by the Union of Concerned Scientists finding that the average new battery electric vehicle in the US produces over 50% less lifetime global warming pollution than comparable internal combustion engine vehicles. While EV manufacturing is more carbon-intensive due to battery production, the operational emissions savings quickly offset this 'debt,' with a mean breakeven point of 21,300 miles for cars. The report advocates for cleaner electricity grids, battery recycling, and increased EV accessibility to accelerate climate benefits.

The Union of Concerned Scientists finds that electric vehicles (EVs) in the United States produce significantly lower lifetime global warming emissions than gasoline vehicles, with the average EV reducing total lifetime emissions by 52% for sedans and 57% for pickup trucks. While EV manufacturing is more carbon-intensive due to battery production, the operational savings quickly offset this 'debt,' with breakeven points occurring between 17,500 and 21,300 miles. The report emphasizes that the emissions benefit of EVs increases as the electricity grid decarbonizes and recommends policies to accelerate renewable energy deployment, improve battery circularity, and increase vehicle efficiency.

The document outlines the evolution of EU CO2 standards for cars and vans, highlighting a 20% reduction target by 2025 and a 100% reduction by 2035 relative to 2021 emissions. It notes the introduction of mandatory Territorial Just Transition Plans for Member States and a requirement for the Commission to report on a common life-cycle CO2 emissions methodology by 2023. The text also observes that proposed interim targets for 2027 and higher 2030 goals failed to pass, potentially slowing the price decrease of electric vehicles.

The European Union is developing a certification mechanism for carbon dioxide removals (CDR) to address the lack of widely accepted standards and reduce risks to the environment and consumer protection. The Clean Air Task Force recommends that the EU adopt a framework based on the IPCC's approach, categorizing methods by removal process and storage timescale rather than the 'natural vs. technological' dichotomy. To ensure integrity, the document proposes that certified removals must be real, measurable, additional, permanent, avoid leakage, and avoid double counting. Additionally, it suggests the creation of EU-level scientific and stakeholder advisory boards to oversee the framework's implementation and its integration into voluntary and compliance markets.

The document argues that the current linear economy, driven by a culture of consumption and planned obsolescence, is unsustainable. It proposes a circular economy based on a systemic approach to maintain resource flows through regeneration and value retention. The authors emphasize that 100% circularity is physically impossible due to thermodynamics, but an optimum can be reached through a design mindset focused on extended life cycles and 'R' activities like remanufacturing and repair. Key barriers identified include outdated waste legislation, intellectual property laws, and consumer norms favoring ownership over access. The paper advocates for the use of public procurement as a lever to create markets for circular business models, such as functional sales where users pay for performance rather than product ownership.
