Climate Central analysis shows that 14 of the 16 host stadiums for the 2026 World Cup are experiencing more extremely hot days during the June-July tournament period than in 1970. Human-caused climate change is responsible for an average of 49% of these extreme heat days across all stadiums, with the highest impact seen in Miami and Mexico City. In 10 repeat host cities, the frequency of extremely hot days has tripled on average since they last hosted the tournament.

The report finds that anthropogenic climate change has significantly increased the probability of dangerous humid heat during the 2026 FIFA World Cup compared to 1994. Using Wet Bulb Globe Temperature (WBGT) as a metric, the analysis indicates that more games are expected to exceed the 26C and 28C thresholds recommended by FIFPRO for cooling breaks and postponement, respectively. While air-conditioned stadiums may mitigate risks for players, spectators at outdoor events remain vulnerable. The study concludes that without substantial adaptation and rapid mitigation of fossil fuel use, hosting summer tournaments in the northern hemisphere will become increasingly hazardous.

The document highlights the health risks posed by extreme heat to players, workers, and fans during the 2026 World Cup, noting that cities like Monterrey, Dallas, and Miami could exceed 35 °C. It discusses FIFA's implementation of three-minute hydration breaks and the potential for shifting match structures to four quarters. Additionally, it addresses the environmental impact of the tournament, specifically the high pollution levels resulting from travel across three host countries, and links these temperature increases to the burning of fossil fuels.

Mexico possesses world-leading solar resources that could technically supply 90% of its electricity when paired with battery storage. While reaching a 45% clean electricity target by 2030 could reduce US gas imports by 20%, a more ambitious 'solar superpower' scenario could eliminate these imports entirely. However, high local installation costs—38% higher for solar and nearly double for batteries compared to global averages—act as a significant barrier to this transition.

The document outlines how climate change increases the prevalence of climate-sensitive diseases and strains healthcare infrastructure, particularly in vulnerable border communities and among migrant populations.

The document outlines how climate change increases the prevalence of climate-sensitive diseases and strains health infrastructure, particularly in lower-income areas and along the U.S.-Mexico border. It highlights the risks faced by migrants and local populations, including heatstroke, Valley fever, and mosquito-borne illnesses, while suggesting specific reporting angles and expert resources.

The report analyzes Mexico's waste sector methane emissions, highlighting a significant increase since 1990 and a lack of integrated data systems. It identifies critical gaps in organic waste treatment, landfill gas capture, and municipal financing, while providing recommendations to strengthen the regulatory framework and improve stakeholder capacity to meet national climate targets.

Following a 2010 tragedy, Tecnológico de Monterrey (Tec) launched DistritoTec in 2014, a district-scale regeneration project in Monterrey, Mexico. The initiative focused on co-creating a shared vision with local residents and business owners to reverse decades of urban sprawl and population decline. By implementing mixed-use development, affordable housing, and 'complete streets'—including over three kilometers of improved pedestrian and cycling infrastructure—the project increased the district's population by 56% and reduced uninhabited homes by 27% between 2010 and 2020. The model, which emphasizes low-carbon mobility and community-led governance through the Neighborhood Council of DistritoTec, is now being replicated in three other districts within the city.

The Sub-national Climate Finance Initiative (SnCF) is designed as a blended finance private equity fund paired with a grant-funded Technical Assistance Facility (TAF) to support mid-sized sustainable infrastructure in developing countries. The Fund targets a total raise of USD 750 million, consisting of a USD 150 million concessional tranche and USD 600 million in commercial capital, aiming to invest in sustainable energy, waste and sanitation, and nature-based solutions. The TAF, targeting USD 28 million, focuses on project preparation, impact certification via Gold Standard, and local government capacity building. The initiative aims to mobilize up to USD 3.8 billion in total finance, with a target of 35-50 projects across up to 20 countries. Key target markets identified include Chile, South Africa, North Macedonia, Mexico, and Jordan. The Fund projects a net IRR of 9.4% for commercial investors and 5.4% for the concessional tranche, with a goal to avoid 77 million tonnes of CO2 equivalent over the infrastructure lifetime.

The report identifies a significant gap between Mexico's current climate-aligned bond issuance and the investment required to meet its emissions targets, while outlining opportunities across energy, transport, buildings, and water sectors.

The report identifies a significant gap between Mexico's climate goals and its current green bond issuance, which stood at US $1.3bn in 2016. It highlights substantial investment needs, particularly in energy (US $5bn annually) and transport (US $12bn for multimodal projects), and argues that mobilizing private institutional capital through green bonds is essential to meet these targets.
