The Clean Air Task Force supports the Green New Deal's goal of net zero greenhouse gas emissions, emphasizing that deep decarbonization requires a diverse portfolio of technologies, including renewables, nuclear power, and carbon capture and storage.

The Union of Concerned Scientists' comparison of ExxonMobil's 2018 and 2019 climate reports finds that the company relies on unchanged energy demand assumptions and maintains a belief that the world will fail to meet Paris Agreement temperature goals. The analysis highlights inconsistencies in how the company describes methane reduction efforts, a lack of detailed low-carbon investment breakdowns, and the use of problematic graphs to suggest alignment with IPCC scenarios. While ExxonMobil acknowledges for the first time that its fossil fuel products are part of the climate problem, it continues to emphasize uncertainty regarding the pace of the global energy transition.

The report finds that the 45Q tax credit could lead to the annual capture and storage of approximately 49 million metric tonnes of CO2 by 2030 in the U.S. power sector, primarily through retrofits on coal and natural gas combined cycle (NGCC) plants. This deployment is found to be complementary to renewable energy growth and could meet two-thirds of the 2030 U.S. power sector goal set by the International Energy Agency (IEA) to limit global temperature rise to 2 degrees Celsius. The analysis emphasizes that the economics of the 45Q credit make enhanced oil recovery (EOR) more favorable than saline storage, necessitating rapid infrastructure development to realize the credit's full potential.

The document describes Arctic wetlands as critical ecosystems that store vast amounts of carbon and support biodiversity and Indigenous livelihoods. It warns that climate-driven permafrost degradation and human activities like drainage turn these areas into a 'time bomb' by releasing greenhouse gases and toxic mercury. Conversely, it argues that restoration and conservation can serve as a 'saving grace' for climate mitigation and adaptation. The briefing highlights the need for better wetland inventories and comparative analysis of management strategies to improve governance across Arctic states.

The document argues that the United States, as a top fossil fuel producer with a resilient economy, must phase out extraction faster than the global average to meet Paris Agreement goals. It introduces three principles: reducing production at a pace consistent with climate protection, accelerating phase-outs in economically resilient communities, and safeguarding human rights and the environment. The authors apply these principles to U.S. coal and onshore oil, identifying the Appalachian Basin and California's San Joaquin basin as high-priority areas for rapid wind-down due to high carbon intensity, lower relative economic dependence, and significant environmental or social harms.

The report finds that while some progress has been made, the world is not yet on track to achieve the 2020 climate turning point. Progress is uneven across the six milestones, with most outcomes designated as having insufficient or off-track progress, though some areas like shipping and public climate finance are on track.

The document examines the link between community land tenure and global sustainability goals, highlighting that while indigenous and rural communities manage over 50% of the world's land, only 10% is legally recognized. It presents evidence that secure tenure reduces deforestation and carbon emissions more cheaply than technological carbon capture. The author calls for legal reforms, simplified formalization procedures, and a more equitable playing field between communities and corporations to protect these critical carbon sinks and support rural livelihoods.

Friends of the Earth U.S. proposes a Green New Deal centered on a total transition to 100 percent renewable energy and ecological agriculture. The platform advocates for the rapid phase-out of fossil fuels, the elimination of subsidies for carbon-intensive industries, and the rejection of unproven technologies like carbon capture and geoengineering. It emphasizes a 'just transition' based on energy democracy, food sovereignty, and the protection of worker rights and frontline communities, while calling for the United States to address its ecological debt to the Global South.

The report asserts that "clean coal" is impossible, detailing the severe impacts of coal mining and combustion in South Africa. It examines technologies like HELE plants, CFB combustion, and CCS, concluding they fail to substantially reduce emissions or costs compared to renewables. It further notes that Eskom and Sasol have frequently sought postponements to comply with national air quality standards.

The report examines how carbon dioxide removal (CDR) and solar radiation modification (SRM) are promoted by fossil fuel interests to justify continued oil, gas, and coal production. It argues that these technologies often rely on fossil fuel by-products or enable enhanced oil recovery, creating a 'moral hazard' that distracts from viable renewable energy transitions.

The document details the operational framework for the 2019 Global Landscape of Climate Finance, defining climate finance as resources aimed at reducing emissions, enhancing greenhouse gas sinks, and increasing resilience to climate impacts. It establishes a standardized accounting methodology to avoid double counting and ensure data consistency across public and private sectors. The methodology prioritizes primary capital flows and financial commitments over disbursements, excluding secondary market transactions and investments that risk carbon lock-in. It provides a comprehensive sectoral breakdown for mitigation (e.g., renewable energy, energy efficiency, low-carbon transport) and adaptation (e.g., water management, coastal protection), and defines the geographic classification of countries into OECD and non-OECD regions.

The document critiques carbon markets, specifically cap-and-trade and offsetting, asserting they fail to reduce global emissions and instead facilitate corporate power and human rights abuses. It highlights the failures of the Clean Development Mechanism (CDM) and REDD, and warns that the negotiation of Article 6 at COP25 could lock in these flawed mechanisms, further delaying urgent emissions cuts at the source.

The report advocates for the development and deployment of zero-carbon hydrogen and ammonia to address sectors that are difficult to electrify. It details production methods such as steam methane reforming with carbon capture and storage (SMR+CCS) and electrolysis, while highlighting the scalability of ammonia due to existing global infrastructure. The document examines applications in heavy-duty transport, marine shipping, and grid-balancing, and calls for coordinated public-private initiatives to manage safety risks and establish supportive policy frameworks.

South Africa's Low-Emission Development Strategy (SA LEDS) 2050 establishes a framework to place the country on a low-carbon trajectory while ensuring socio-economic development. The strategy focuses on a 'peak, plateau and decline' (PPD) emissions trajectory, with a peak projected between 2020 and 2025. Key interventions span the energy sector (diversifying the electricity mix via the Integrated Resource Plan and REIPPP), industry (energy efficiency and carbon taxes), AFOLU (conservation agriculture and afforestation), and waste (waste-to-energy and recycling). The document emphasizes a 'Just Transition' to protect vulnerable workers and communities, supported by research into hydrogen, fuel cells, and carbon capture and storage. Implementation relies on a combination of domestic funding and international climate finance.

The study found that four existing ozone damage functions used in terrestrial biosphere models failed to accurately reproduce observed ozone-induced biomass reductions in young European trees. However, the authors achieved a good agreement between observed and modelled damage by developing linear, plant-functional-type-specific dose-response relationships through the re-parameterisation of photosynthetically based injury functions.

Cement production accounts for 5.6% of global CO2 emissions, split between thermal fuel combustion (30-40%) and limestone calcination process emissions (60-70%). The report highlights that concrete naturally re-absorbs CO2 through carbonation, sequestering roughly 48% of process emissions over several decades. To reach carbon neutrality by 2050, the author models scenarios suggesting that capturing 80% of process emissions is sufficient if electricity is decarbonized, or 53% if thermal fuels are also fully decarbonized. Mitigation strategies discussed include energy efficiency, clinker substitution (reducing clinker content to 60%), and novel technologies from CarbonCure and Solidia.

The document finds that while some countries have improved their legal frameworks to combat deforestation, implementation remains weak due to corruption, lack of resources, and a failure to recognize the land rights of indigenous peoples and local communities (IPLCs). It highlights a strong correlation between high corruption and forest loss, and notes that illegal conversion for commercial agriculture—specifically palm oil, soy, paper/timber, and cattle—drives much tropical deforestation. While demand-side measures for timber are increasing in the EU, US, and Asia, similar measures for other commodities remain largely voluntary. The report also emphasizes the critical role of IPLCs in carbon storage, noting they manage 17% of total carbon in 64 assessed countries, yet face increasing violence and land grabbing due to insecure tenure.

The report finds that while some countries have strengthened forest laws, overall governance remains weak, particularly in poor nations. Illegal deforestation is endemic, driven by commercial agriculture for palm oil, soy, and beef. Progress in recognizing the land rights of indigenous peoples and local communities (IPLCs) is slow, and the lack of secure tenure contributes to increased violence and land grabbing. The report emphasizes that strong governance and the empowerment of IPLCs are essential for effective forest protection.

The report finds that while some countries have strengthened forest laws, implementation remains slow and often undermined by corruption and a lack of political will. Illegal deforestation is driven largely by commercial agriculture, particularly in Brazil and Indonesia. Progress in recognizing the land rights of indigenous peoples and local communities (IPLCs) is slow, and these groups face increasing violence and criminalization. While some emerging economies in Asia are adopting regulations to curb illegal timber imports, overall forest governance remains fragile, particularly in poorer nations.

The 2018 Northern Great Plains Donor Report details WWF's efforts to conserve grassland ecosystems through several key pillars. These include a Ranch Transition Pilot Project to address the risk of 56 million acres of farmland changing hands, and the development of a soil suitability model extending into Canada to predict crop conversion. Bison restoration efforts aim to establish five conservation herds of at least 1,000 bison each by 2025, with significant progress made at Fort Peck Reservation. For endangered species, WWF is testing Fipronil and vaccine baits to combat sylvatic plague in black-footed ferrets and prairie dogs. Additionally, the report highlights the Tribal Working Group on Sustainable Financing's work on tourism assessments and conservation planning for the Lower Brule Sioux Tribe, alongside collaborations with the US Roundtable for Sustainable Beef to implement sustainability metrics in the beef supply chain.
