What is sustainability?

Understand what sustainability is, why it’s important, and the actions you can take to live more sustainably.

Sustainability is defined as ‘meeting the needs of the present without compromising the ability of future generations to meet their own needs’ by the United Nations Brundtland Commission.

When meeting our needs for things like energy, food, housing, and travel, we should only use what we can replace, protect the resources and materials we all depend on, and make sure everyone benefits equitably.

Sustainability helps to improve:

  • the planet, by making sure there is clean air and water, healthy soils and thriving wildlife
  • people’s lives, by committing to fairness, health, safety, and opportunity for all
  • prosperity, by using resources wisely so they last for generations to come

Sustainable Development Goals

The United Nations Sustainable Development Goals (SDGs) are a set of 17 global goals created by all UN member states and adopted in 2015.


Sustainable Development Goals are part of the 2030 Agenda for Sustainable Development. This is the world’s shared plan to make life better for people and the planet by the year 2030.

The SDGs have been designed to:

  • improve livelihoods
  • end extreme poverty
  • reduce inequality
  • protect the environment
  • improve economic growth

At the same time, they aim to tackle pressing global concerns like conflict, climate change and biodiversity loss, and protect the Earth and its resources for future generations.

The 17 Goals are all interconnected and interdependent so they shouldn’t be viewed in isolation. To make sure everyone benefits fairly, it’s important that we tackle them all.

A better future is everyone’s responsibility

There are lots of ways we can all contribute to a sustainable future, no matter our background, expertise or income.


Everyone’s contribution is vital to make sure that solutions are inclusive, just and lasting. For example, you can:

  • use your voice to share your knowledge and encourage others to be more sustainable
  • take action at work or where you study by following sustainable working practices, supporting wellbeing, and influencing those around you
  • change your personal behaviours by using less energy, travelling by low-carbon methods, buying and wasting less, and eating more plant-based foods
  • be an active citizen by campaigning for change, voting in elections, spending wisely and ethically, and engaging with your community
  • care for nature by creating more green spaces, and protecting plants, water, habitats and wildlife
  • support the sustainability of people by committing to safe working environments, fair pay, and equal and inclusive health, wellbeing and education
  • share and increase your knowledge through education and research, and talking to others about living sustainably

Our responsibility as a university


At Bath, we have a unique opportunity to support a pathway to a sustainable future.

Through the education we provide, we’re empowering our students with the knowledge and skills to help tackle global challenges.

Through our research, we’re seeking to find ways we can create a better and healthier world for people and planet.

However, we know that there are environmental and social impacts associated with our activities. We:

  • have many buildings, labs and student residences
  • move thousands of people for education and research throughout the year
  • buy lots of products and services

We want to maximise our contribution to a more sustainable world while minimising our negative impact.

To help us achieve this, we have a Sustainability Policy outlining our approach.

We also publish annual reports transparently outlining our progress and challenges for sustainability.
