Houston Airports is committed to carbon neutrality by 2030

Defining sustainability

Houston Airports adopted the triple-bottom-line definition of sustainability, which defines the need to be responsible stewards of the airport system’s financial, natural and people resources.

Sustainability is not only about minimizing effects on resources, but also recognizing the role of airports in creating enduring communities, acknowledging the social costs of air travel, and creating airports that are resilient to future stresses such as energy or water scarcity.

Sustainability is about operating airports in an efficient and responsible manner now and into the future.


Houston Airports is furthering carbon management and emissions reductions by seeking accreditation in the Airports Council International, ACI, Airport Carbon Accreditation process. The ACA process will map our current carbon footprint and provide the framework needed to reduce our carbon footprint to meet our initial goal of becoming carbon neutral by 2030.

The first requirement of the ACA process is to make a policy commitment to emissions reduction. With this statement, we have committed to calculate an annual greenhouse gas inventory, per for the ACA guidelines, for all three airports: George Bush Intercontinental Airport, William P. Hobby Airport and Ellington Airport.

Sustainable Management Plan

The Houston Airport System takes pride in maintaining a safe and dynamic air services network that fosters economic vitality for the transportation industry and facilities a strong level of global connectivity. From fleet services to terminal improvements, Houston Airports manages many aspects of airport operations while simultaneously enhancing the passenger experience.

In 2018, Houston Airports became one of 10 airports nationwide to finalize a Federal Aviation Administration approved sustainable management plan. The plan demonstrates the airport system’s continued commitment or provide world-class air service, operational efficiency and customer service while striving to become more sustainable.

In the five years that followed, Houston Airports committed to reducing its environmental impact in seven categories including energy, water, greenhouse gas emissions and sustainable design.

This Sustainable Management Plan is critical to the Strategic Priorities of Houston Airports:

  • Make our passengers happy 
  • Achieve “opening day fresh” conditions for our airports
  • Build the platforms for future success
  • Invest in our partnerships and our employees

The Houston Airports design standard is a minimum of 20% better than the 2015 International Energy Conservation Code. Our standard is currently being utilized in the construction of several buildings at Bush Airport, including the Federal Inspection Services building and the Mickey Leland International Terminal, which are part of the International Terminal Redevelopment Program.
