The document argues that climate change impacts are not equal and are influenced by intersectional factors such as race, gender, power, and poverty. It provides examples of coalitions uniting debt activists, homeless advocates, racial justice groups, indigenous leaders, women's rights organisations, and labour unions to address systemic inequalities alongside the energy transition. These collaborations range from demanding unconditional debt cancellation for the Global South and vaccine equality to promoting 'carbon banks' for Black farmers in the US and integrating trans rights into environmental movements. The briefing highlights that integrating a social justice lens—recognising interacting systems of oppression—is essential for a diverse and effective climate movement.

The IEA Net Zero Scenario projects a massive expansion of solar and wind energy, with solar and wind together providing almost 70% of global electricity by 2050. It calls for an immediate end to new oil, gas, and unabated coal investments, forecasting a 90% decline in coal demand and a 275% decline in oil use by 2050. The transition relies heavily on the scaling of currently non-commercially viable technologies, including CCUS, hydrogen, and negative emission technologies (NETs), as well as a 60% increase in bioenergy use.

The document argues that agroecology, a science-based set of practices and social movement, offers a sustainable alternative to industrial agriculture, which accounts for up to 37% of global greenhouse gas emissions. It highlights that approximately 30% of global farms have already adopted agroecological principles, leading to increased crop yields, higher farmer incomes, and improved biodiversity. However, the briefing notes that scaling up these practices is hindered by governance and finance systems that heavily subsidize industrial agriculture, with only 1%-1.5% of agricultural and aid budgets currently supporting agroecological approaches. To overcome these barriers, the document recommends reorienting public funding, integrating agroecology into research and education, and increasing the participation of small-scale producers in food governance.

The document emphasizes that because CO2 is cumulative, delays in emission cuts lead to higher peak temperatures and greater ecological damage. It warns that overshooting the 1.5°C target and relying on underdeveloped negative emissions technologies (NETs) poses significant risks to marine ecosystems and biodiversity. The author advocates for transparent, comprehensive greenhouse gas mitigation plans and a 'green recovery' from COVID-19, noting that the economic and public health benefits of rapid decarbonization far outweigh the costs.

The document outlines the accelerating degradation of the Earth's cryosphere and oceans due to climate change. It details the rapid loss of ice sheets in Greenland and Antarctica, the thawing of permafrost, and the warming, acidification, and deoxygenation of the global oceans. These changes drive sea level rise, threaten biodiversity, and disrupt essential services like freshwater supply from mountain glaciers and food security from fisheries. The briefing emphasizes that while some damage is irreversible, cutting emissions can reduce risks and facilitate adaptation for vulnerable coastal and indigenous populations.

The document analyzes how human land use drives climate change and how climate change, in turn, degrades land. It highlights that while land currently acts as a net carbon sink, it could become a source of emissions. The brief emphasizes the role of agriculture and deforestation in land degradation and warns that current policy trajectories could significantly expand drylands and threaten global food security. It argues that sustainable land management, incorporating indigenous knowledge and gender-sensitive policies, is essential for limiting temperature rise to 1.5°C.

The document compares how different jurisdictions integrate climate change into environmental law. It finds that while the EU and New Zealand have explicit requirements for climate considerations in assessments, the US and Canada rely on guidance or separate acts rather than the primary environmental laws. The UK uses a combination of the Environment Act 2021 and the Climate Change Act 2008 to manage emissions and accountability.

The document presents a comparative analysis of multiple carbon dioxide removal (CDR) technologies and nature-based solutions, detailing their Technology Readiness Levels (TRL), estimated costs per tonne of CO2, and annual mitigation potentials. It highlights that while some methods like afforestation and BECCS have substantial contributions in Integrated Assessment Models (IAMs), others such as biochar and soil carbon sequestration are still in development or not yet incorporated into these global pathways. The analysis also weighs the co-benefits, such as improved biodiversity and soil health, against risks including land competition with food production and potential carbon reversal.

The report by Zero Carbon Analytics (ZCA) highlights the severe health and economic costs associated with the overconsumption of red and processed meats. Using data from the Global Burden of Disease study, ZCA finds that processed meat caused 295,000 deaths and red meat caused 334,000 deaths globally in 2021. The economic impact reached USD 285 billion in 2020. The analysis reveals a 'treatment-over-prevention' trend in wealthy nations—specifically in Europe, North America, Oceania, and Asia—where robust healthcare systems spend heavily to manage preventable chronic diseases rather than investing in dietary prevention. For example, Switzerland may spend up to USD 99,000 to avert one disability-adjusted life year (DALY) from processed meat. The report argues that a 30% reduction in the disease burden from processed meat could save billions annually in the US, Germany, UK, and France, allowing for the redirection of funds toward other health priorities, such as nursing staff.
