In June 2013, Mexico implemented Latin America's first fuel-efficiency standard for light vehicles, developed with support from EMBARQ Mexico and Centro Mario Molina. The standard mandates a fleet average of 14.9 kilometers per liter by 2016, aiming to reduce CO2 emissions by 170 megatons and save consumers $2,700 USD per vehicle over its lifetime. By aligning with U.S. and Canadian regulations, Mexico has harmonized its standards, potentially increasing the global competitiveness of its automotive industry.

The Yucatan Peninsula Accord, signed in December 2010 by the states of Campeche, Quintana Roo, and Yucatan, represents Mexico's first sub-national regional climate agreement. The Accord aims to reduce vulnerabilities of local and indigenous populations through a joint low-carbon development scheme consisting of a regional adaptation strategy, a REDD+ programme in the Sian Kaan-Calakmul forest corridor, and a regional climate fund dedicated to scientific research. The document highlights that pooling resources at the sub-national level helped the participating states attract international and national funding that they could not secure individually. Key challenges identified include a lack of climate legal expertise among civil servants and the need to balance regional cooperation with state autonomy.

The document argues that the IFC's draft Sustainability Framework fails to adequately protect human rights, noting that references to human rights were removed from previous drafts. The signatories call for mandatory human rights due diligence for both the IFC and its clients, alignment with the UN 'Protect, Respect and Remedy' framework, and specific safeguards regarding water rights, gender impacts, forced evictions, and environmental damage.

The report outlines the results of expert dialogues held between 2009 and 2010 focused on North American energy and climate collaboration. It highlights a period of significant political uncertainty, particularly regarding U.S. federal legislation, and argues that Canada and Mexico must engage actively in policy discussions to avoid becoming "policy takers." Key areas for cooperation include carbon pricing, renewable energy investment, carbon capture and storage (CCS), and transportation fuel standards. The document emphasizes that while a unified "North American Bubble" for emissions targets is unlikely, pragmatic, sector-specific coordination and the harmonization of technical standards offer viable paths forward in the absence of a continental regulatory framework.

The report documents that commuters in cars, buses, trains, and ferries are routinely exposed to high levels of diesel exhaust, with ultrafine particles (UFPs) serving as the most sensitive marker of fresh diesel emissions. Findings indicate that diesel soot dominates roadway particulate matter and that in-vehicle exposures are significantly higher than ambient outdoor air, particularly in 'pull' trains and highway tunnels. The study concludes that diesel particulate filters (DPFs) are highly effective at eliminating the soot plume behind vehicles, significantly improving air quality for following commuters and pedestrians.

The ADAPTE project investigates the interaction between air pollution and extreme weather on human health in Latin American cities, specifically focusing on Mexico City, Santiago, Buenos Aires, and Bogotá. Initial findings indicate that suspended particles and nitrogen oxides in these cities significantly exceed WHO standards, with vulnerability varying by age, sex, income, and season.

The document analyzes the outcomes of COP15 for REDD-plus, highlighting the Copenhagen Accord's role as a political mandate for further action. It details the three-phase implementation approach proposed by the AWG-LCA and examines critical challenges including the definition of 'forest', the integration of REDD into Nationally Appropriate Mitigation Actions (NAMA), and the development of Monitoring, Reporting, and Verification (MRV) systems based on IPCC guidelines. The report also discusses the necessity of social and environmental safeguards for indigenous peoples and local communities, the role of the Green Climate Fund, and the potential for both grant-based and market-based financing mechanisms.

The ADAPTE project uses GIS to map the interaction between air pollution and extreme weather (heat and cold waves) to identify health risks in Latin American cities. Findings indicate that PM10 and NOx levels in Mexico City, Santiago, and Bogota significantly exceed WHO standards. The project identifies varying relative risks (RR) for respiratory and cardiovascular mortality based on season and age group, such as higher respiratory risk for children in Bogota during the cold season.

The document details the ADAPTE project, which uses GIS to map social vulnerability and mortality risks linked to air pollution and temperature extremes in Latin American cities. It highlights that PM10 and NOx levels in Mexico City, Santiago, and Bogotá significantly exceed WHO standards and notes that respiratory and cardiovascular mortality risks vary by age group and season, particularly in Bogotá.

The report examines the transition from traditional, inefficient bus services to modernized systems, primarily Bus Rapid Transit (BRT), across 13 cities in Latin America and Asia. It highlights that while these systems generally improve travel speed, reduce emissions, and lower capital costs compared to rail, they often suffer from rushed implementation, inadequate user education, and financial instability due to politically determined fares. The analysis emphasizes the importance of high-level political commitment, comprehensive planning, and the use of technical fare-setting to ensure long-term sustainability.

The 'Manuel de formation sur l’EEI' is a comprehensive training tool developed by UNEP and partners to strengthen capacities in integrated environmental assessment (IEA). It defines IEA as a process to produce future-oriented policy information on interactions between the natural environment and human society. The manual is structured into two volumes: Volume 1 covers eight basic methodological modules (ranging from process design and impact strategies to scenario analysis and communication), and Volume 2 provides thematic modules, specifically focusing on Vulnerability and Impact Assessments for climate change adaptation (VIA). The training emphasizes a participatory, interactive approach and is supported by a digital platform and an e-learning version to facilitate global collaboration and continuous learning among practitioners.

The document outlines a modular training framework developed by UNEP and IISD to help practitioners conduct integrated environmental assessments. It describes eight core methodological modules—covering everything from process design and impact strategies to data monitoring and scenario analysis—and a thematic module focused on climate change vulnerability and adaptation. The manual emphasizes a collaborative, iterative process aimed at informing policy decisions and improving environmental governance at national and regional scales.

The Clean Air Task Force (CATF) conducted monitoring in Austin, Boston, New York City, and Columbus to assess diesel exhaust exposure during commutes. The study found that commuters in cars, buses, and trains are exposed to diesel particle levels significantly higher than ambient outdoor air, with the highest concentrations occurring in the presence of heavy truck traffic or when trains are pulled by locomotives. The report highlights that while commuting accounts for only about 6% of a person's day, it may contribute over half of their daily exposure to ultrafine particles. To mitigate these risks, the report recommends retrofitting existing diesel engines with diesel particulate filters (DPFs), which can reduce particle emissions by up to 90%.

The Standing Committee on Rules and Procedures reports that its primary activity for the year was responding to a consultation regarding the selection process for the IAI Executive Council and its Board, stating otherwise that it was a quiet year with no other assigned tasks.

The report details how African Americans are disproportionately exposed to power plant emissions due to residential concentration in urban centers and proximity to facilities. It links these emissions to higher rates of asthma, infant mortality, and mercury exposure, while highlighting the compounding effects of poverty and lack of healthcare. The authors advocate for new legislation to reduce sulfur dioxide, nitrogen oxides, mercury, and carbon dioxide, and specifically call for the elimination of the 'grandfather' exemption in the Clean Air Act's New Source Review program.

The document examines how NAFTA's Chapter 11 provisions—specifically those regarding expropriation, national treatment, and performance requirements—can be used by investors to challenge environmental regulations. It highlights a lack of transparency and accountability in the ad hoc investor-state dispute process and suggests that the Joint Public Advisory Committee (JPAC) should push the Commission for Environmental Cooperation (CEC) and the Free Trade Commission (FTC) to reform these mechanisms to better balance investor rights with public interest.

The report details how power plant emissions—including particulate matter, ozone, sulfur dioxide, and mercury—disproportionately harm children due to their developing physiology and higher activity levels. It links these pollutants to asthma, stunted lung growth, neurological deficits, and infant mortality, while advocating for nationwide emission caps and a transition to cleaner energy.

The agreement between the Federative Republic of Brazil and the Inter-American Institute for Global Change Research (IAI) defines the operational status of the IAI headquarters in Brazil. It grants the IAI juridical personality and establishes extensive immunities for its premises, funds, and archives, protecting them from search, requisition, or execution. The Brazilian government provides specific physical facilities at the Instituto Nacional de Pesquisas Espaciais (INPE), including office space, equipment, and administrative staff. The agreement also outlines diplomatic privileges and immunities for the IAI Director and staff, including tax exemptions and freedom of movement, while requiring the IAI to respect Brazilian laws and cooperate with local authorities.

The document is a directory of delegations, observers, and secretariat staff attending the First Meeting of the Conference of the Parties in September 1994. It lists representatives from various national governments, scientific institutions, and international organizations, including the National Science Foundation and the Inter-American Institute for Global Change Research.

The report highlights that tropospheric ozone is a potent greenhouse gas and air pollutant responsible for approximately 0.23°C of present-day warming and nearly 500,000 premature deaths annually. It is not emitted directly but forms from precursors like methane, nitrogen oxides (NOx), non-methane volatile organic compounds (NMVOCs), and carbon monoxide (CO). The document identifies a significant gap in global climate strategies, noting that tropospheric ozone is largely absent from the Paris Agreement and most Nationally Determined Contributions (NDCs). It provides sector-specific policy levers—ranging from methane capture in oil and gas to electric vehicle adoption in transport—and presents case studies from Los Angeles, Mexico City, Beijing, and Europe to demonstrate the effectiveness of targeted pollution control. The report concludes with recommendations for policymakers to adopt multi-pollutant approaches, for scientists to fill knowledge gaps in regional climate effects, and for funders to increase the currently insufficient international development funding for outdoor air pollution.
