What is Sustainability?

Sustainability means taking proactive steps to protect Austin's quality of life now and for future generations. Sustainability is about finding a balance among three sets of goals:

An icon of three people. Shorter people stand on boxes so they are all the same height. An icon of the earth. An icon of a bar chart with lines growing upward. A dollar sign is next to it.

People & Equity

Ensuring community health, equity, and cultural vitality.

Planet & Environment

Practicing conservation for the health of our environment.

Economy & Prosperity

Supporting prosperity and promoting jobs.


What We Do

Brief and advise City of Austin department directors, the City Manager, Boards & Commissions, the Mayor, and City Council about sustainability aspects of City policies, programs, and initiatives.

Oversee and coordinate activities with departments that accomplish operational objectives sustainably, including green purchasing, energy conservation, recycling, green building, resource and water conservation, greenhouse gas reduction, and environmental reporting metrics.

Manage the Climate Program and related actions to reduce the City’s carbon footprint and be more resilient to the effects of climate change.

Offer educational outreach on conservation and sustainability initiatives to engage the community in making sustainability a priority – at home, at work, and all around town. We seek ways to inspire Austinites to take action for a bright green future for our community.

Promote partnerships and work with community members, organizations, and other government agencies to establish sustainability programs and practices.
