The Union of Concerned Scientists is launching a national campaign to protect government scientists and scientific research from political attacks, specifically citing the Project 2025 agenda as a source of intensified threats. The organization intends to combat disinformation, hold corporate actors accountable, and advance clean energy and democracy goals at the state level to mitigate federal-level risks to climate progress, transportation, and global security.

Peru is implementing a phased roadmap to establish a national monitoring and evaluation (M&E) system for climate change adaptation, aligned with its National Adaptation Plan (NAP) and Nationally Determined Contribution (NDC). The system focuses on seven priority sectors—water, agriculture, fisheries and aquaculture, forest, health, tourism, and transport—and aims to be fully operational by 2030. The process is divided into four phases: Analysis (completed), Design (underway), Development (underway), and Implementation (not started). Recent progress includes the creation of a final project design, interoperability proposals for data exchange with the National Environmental Information System, and the establishment of a baseline for loss and damage indicators.

The document outlines the technical framework for the State of Climate Action series, focusing on tracking global greenhouse gas emission reductions and carbon removal. It details the process of translating sectoral transformations into actionable targets and the categorization of progress (e.g., 'on track' or 'off track'). The 2024 update introduces 2035 targets for 16 indicators, a new indicator for wind and solar power in electricity generation, and revised transport sector targets based on recent modeling.

The report details the implementation of Phase 2 of Rwanda's climate adaptation Monitoring, Evaluation, and Learning (MEL) system. Following a pilot in the agriculture sector, this phase focused on tracking seven specific adaptation indicators from Rwanda's Nationally Determined Contribution (NDC)—four in human settlements and three in transport—to evaluate the effectiveness of adaptation initiatives and inform future strategies.

The report finds that international concessional climate finance grew by 50% from 2019 to reach USD 81 billion in 2022, though it remains small compared to fossil fuel subsidies. Sub-Saharan Africa is the primary recipient of these flows. The analysis highlights a gap in adaptation finance and a lack of standardized impact metrics. Domestic concessional finance is heavily concentrated in high-income economies, particularly Western Europe, and focuses primarily on mitigation. The report recommends redirecting fossil fuel subsidies, targeting fragile and conflict-affected states, and streamlining project approval processes to enhance efficiency.

The guide argues against one-size-fits-all climate action lists, instead encouraging individuals to audit their own habits in four key areas: diet, electricity use, travel, and home temperature regulation. It highlights the environmental impact of agriculture, fossil-fuel electricity, and transportation, offering specific practical steps—such as shifting to plant-rich diets, upgrading to LED bulbs, and reducing air travel—to lower personal greenhouse gas emissions.

A fact-checking cell composed of experts from QuotaClimat, INRAE, the Institut Rousseau, Egis, and Blunomy analyzed ecological statements made during the May 2, 2024, European election debate. The cell found that ecology was not a priority for the moderators, leading to a lack of discussion on key transition themes such as agriculture, energy, and transport. Specific claims by candidates were flagged as false or misleading: Léo Deffontaines' claim about energy production for carbon neutrality was deemed partially false for omitting energy sobriety; Manon Aubry's figures for taxing super-profits and super-fortunes (125 and 250 billion euros) were identified as global rather than European estimates; and François-Xavier Bellamy's claims regarding French taxation and public spending levels were labeled as fallacious or false based on GDP percentages and investment needs.

The report provides a comprehensive vulnerability assessment for the Kintampo Municipal Assembly, identifying agriculture as the most sensitive sector. It combines historical climate data (1980–2020) with future projections to 2100, highlighting increasing temperatures and variable rainfall. The study identifies specific community-level vulnerabilities, with Busuama being the most vulnerable and Kintampo the least, and recommends targeted adaptation strategies including conservation agriculture, irrigation, and gender-responsive initiatives.

The SAVi assessment of the Tirana–Durres railway in Albania reveals that while the project is not economically viable under conventional financial metrics (BCR of 0.12), it is highly profitable from a societal perspective with a Sustainable Benefit-Cost Ratio (S-BCR) of 4.79. Over a 30-year period (2023–2053), the project is projected to generate cumulative discounted net benefits of EUR 270.34 million. The most significant financial gains come from avoided vehicle operating costs (EUR 96.79 million), followed by health benefits (EUR 44.93 million), time savings (EUR 44.39 million), and avoided accident costs (EUR 41.61 million). The report argues that integrating non-tangible social and environmental externalities—such as reduced CO2 emissions and improved public health—provides a stronger business case for sustainable transport infrastructure in Albania.

The report details how climate change threatens the Port Authority of New York and New Jersey (PANYNJ) through sea level rise, intense storms, and extreme heat. It provides specific projections for sea level rise in New Jersey and New York City, notes the increasing frequency of 'nuisance flooding' at The Battery, and highlights the vulnerability of critical assets like LaGuardia Airport's Runway 13/31. The document quantifies historical damages, such as the billions lost during Superstorm Sandy, and lists a comprehensive set of potential adaptation costs, including flood-proofing buildings, elevating infrastructure, and mitigating heat-induced rail and road degradation.

The EPA has launched Phase 2 of the Climate Pollution Reduction Grants (CPRG) program, offering $4.3 billion in a general competition and $300 million for tribes and territories to implement Priority Climate Action Plans (PCAP). Eligible projects must focus on greenhouse gas (GHG) reduction across sectors such as electric power, transportation, and industry, with a strict application deadline of April 1, 2024. The document advises states and municipalities to proactively coordinate and engage underserved communities to maximize funding opportunities within the tight timeframe.

Average annual climate finance reached nearly USD 1.3 trillion in 2021/2022, nearly doubling from 2019/2020 levels, though this remains only 1% of global GDP. Growth was primarily driven by mitigation finance in energy and transport, with significant concentration in China, the US, Europe, Brazil, Japan, and India. Adaptation finance, while reaching a record USD 63 billion, remains severely underfunded compared to the USD 212 billion annual need for developing countries by 2030. The report highlights a critical investment gap, noting that annual needs will increase to between $8.1 and $9 trillion through 2030, and over $10 trillion annually from 2031 to 2050.

The analysis of over 800,000 responses from the Klimatkalkylatorn tool reveals that the average Swedish household carbon footprint is 4.3 tons CO2e per person, with significant variations based on municipality type, income, and family structure. Food is the largest emission driver overall, while air travel causes the widest disparities between households. The study highlights that residents in commuting municipalities near large cities often have the highest footprints, whereas those in large cities have the lowest overall footprints, primarily due to reduced car travel.

The document argues that energy efficiency is essential for climate and development goals and can be accelerated by shifting individual and business decision-making through positive, emotion-based narratives. It outlines a framework for communication based on four pillars: empowering people, fostering positive emotional connections, recognizing champions, and innovating communication channels. The compendium utilizes case studies from G20 countries across sectors including buildings, industry, and transport to share lessons for global energy-efficiency actions.

The briefing asserts that current Nationally Determined Contributions are collectively insufficient to meet Paris Agreement temperature goals, necessitating that the Global Stocktake provide clear, sector-specific mitigation actions and targets. It proposes a comprehensive list of actions—including phasing out fossil fuels and subsidies, boosting renewables, and decarbonizing industry—to inform the 2030 and 2035 time horizons. The author suggests these outputs be integrated into the CMA cover decision or technical annexes and provide a structured guidance framework for Parties to update their NDCs with achievable targets aligned with IPCC emission reduction goals.

The document defines 'high-hanging fruit' as decarbonisation measures that are inaccessible to host governments due to extraordinary costs or insurmountable barriers. It argues that these projects are essential for enhancing overall climate ambition and proposes a shift in how voluntary climate finance and carbon crediting mechanisms identify and fund them. The author suggests redefining 'additionality' to include project inaccessibility, introducing specific labels for such projects, establishing dedicated funds for climate contributions, and calling for leadership from corporations and intermediaries to develop a project pipeline.

The research finds that a higher number of climate policies is associated with lower projected emission change rates up to 2030, a result that remains robust when controlling for GDP, historical emissions, and the rule of law. The study identifies specific policy gaps based on emission trends: countries with fast-increasing emissions lack policies in energy-demand sectors like buildings and transport, while those with stalling emissions lack cross-sectoral climate strategies. Across all groups failing to reduce emissions, there is a notable deficiency in policies targeting the reduction of energy and material demand.

The research evaluates climate neutrality trajectories in nine Swedish cities, finding that while political will and targets are strong, there are significant gaps in transport, construction, and food sectors. The authors highlight a disconnect between intent and outcomes, noting that the reliance on 'soft' policy instruments and contradictory economic incentives hinders progress, and recommend a shift toward more regulatory instruments and better alignment with superordinate governments.

The report analyzes the intersection of climate-resilient infrastructure and gender disparities in 19 African countries. It identifies how climate change disproportionately affects women—increasing labor burdens for food, water, and energy—and how inadequate infrastructure exacerbates these vulnerabilities. The document provides detailed socioeconomic profiles for several countries, including Benin, Cameroon, Chad, and Nigeria, highlighting gaps in education, financial inclusion, and political representation. To mitigate these risks, the ICRF proposes a three-component strategy involving blended finance, capacity building, and policy interventions, with specific entry points for gender mainstreaming such as prioritizing women-led companies in procurement and collecting sex-disaggregated data.

The report establishes a baseline emissions inventory for the Genesee-Finger Lakes Region, identifying transportation, agriculture, and residential heating as primary emission sources. It details a methodology aligned with New York State and IPCC guidelines, providing county-level breakdowns and a baseline projection that suggests a slight increase in total emissions by 2050.
