Mexico and the United States Join Forces to Combat Carbon Footprint

Over the past decade, Mexico and the United States have intensified their efforts to reduce greenhouse gas (GHG) emissions, focusing on urban policies that promote reforestation and the use of clean transportation. This article analyzes the initiatives implemented between 2017 and 2024, comparing key statistics and exploring the challenges both countries face in 2025 to maximize the impact of these policies.

GHG Emissions Trends

 Mexico: In 2015, Mexico emitted approximately 683 million metric tons of CO₂ equivalent (MtCO₂e). By 2021, emissions had risen to over 714 MtCO₂e, accounting for 1.4% of global emissions. This 4.5% increase over six years highlights challenges in effectively implementing emission reduction policies.

United States: Between 1990 and 2017, CO₂ emissions in the U.S. increased by 2.9%. However, in 2023, emissions decreased by 2.19% compared to the previous year, reaching 4,682 MtCO₂e. This downward trend indicates progress in clean energy policies and sustainable transportation.

Reforestation and Clean Transportation Initiatives

Reforestation in Mexico: The "Sembrando Vida" program has been a cornerstone of reforestation efforts. In 2024, President Claudia Sheinbaum proposed at the G-20 to allocate 1% of global military spending to a worldwide reforestation program inspired by this initiative. Additionally, the inauguration of Parque Ecológico Lago de Texcoco in 2023 added one of the world's largest urban green spaces, strengthening biodiversity and serving as a carbon sink.

Clean Transportation in Mexico: The Clean Transportation Program, a collaboration between the Ministry of Communications and Transportation (SCT) and the Ministry of Environment and Natural Resources (SEMARNAT), aims to make freight and passenger transport more efficient and environmentally friendly. This program promotes the adoption of technologies and practices that reduce fuel consumption and GHG emissions.

Clean Transportation in the United States: Cities like Houston have led the transition to renewable energy, becoming global references in clean technologies. Additionally, in 2024, the company CAF, through its subsidiary Solaris, secured its first contract to supply electric buses in Seattle, reflecting a growing commitment to sustainable transportation.

Challenges for 2025

Despite progress, both countries face significant challenges for 2025:

1. Sustainable Financing: The implementation and expansion of reforestation and clean transportation programs require substantial investments. Alicia Bárcena, Mexico’s Secretary of the Environment, has emphasized the need to increase the budget for environmental projects, expressing optimism about securing additional resources.

2. Bilateral Coordination: Collaboration between Mexico and the United States is essential to address transboundary environmental issues. The "Border 2025: Mexico-U.S. Environmental Program" seeks to tackle environmental challenges in the border region, promoting an integrated approach and joint actions.

3. Technological Adaptation: The transition to clean technologies in transportation and energy requires continuous updates and adaptation to new solutions. Investment in research and development is crucial to maintaining momentum toward sustainability.

4. Public Awareness and Participation: Fostering an environmental culture among the population is vital for the success of these initiatives. Education and active participation from civil society can accelerate the adoption of sustainable practices.

Mexico and the United States have laid the groundwork for carbon emission reduction through reforestation and clean transportation initiatives, but there is still a long way to go. Looking ahead to 2030, investment in sustainable solutions will be key to meeting emission reduction commitments established in international agreements such as the Paris Agreement and the UN Sustainable Development Goals (SDGs). The challenge is clear: Can Mexico and the United States transform their cities into models of sustainable urban development? The answer will depend on the decisions they make in the coming years.
