Sustainable World

In a sustainable world, resources are used to meet the needs of the present without compromising the future. Environmental protection, social well-being, and economic stability go hand in hand, promoting practices that preserve natural ecosystems, reduce waste, and encourage responsible consumption.

Exploring the psychology of long-term thinking, communication, and environmental action

At Essex, our team of psychologists are uncovering how people make decisions about sustainability, how they process risks, and what motivates meaningful environmental action to help us understand our place in an ever-changing world.

Our research explores how we can foster long-term thinking, communicate uncertainty more effectively, and challenge social norms that may stand in the way of change.

Some recent highlights

Future thinking drives action

Planning for the future doesn’t just help individuals, it helps the planet.

Our research shows that when people mentally simulate future outcomes, they’re more likely to engage in high-impact sustainable behaviours, like reducing meat consumption or supporting environmental policies.

The power of language in climate communication

How we talk about climate risks matters. Our studies show that framing rare but impactful events, like floods or rising sea levels, with positive probability language (for example “a small chance”) rather than negative terms (for example “unlikely”) helps people take risk more seriously.

Positive framing also builds trust in forecasters and promotes thoughtful decision-making.

Recognising rare risks

From wildfires to flash floods, rare disasters are becoming more frequent and costly. Yet, people often downplay them because of their perceived unlikelihood.

Essex researchers are investigating how to raise awareness of these low-probability, high-impact events so communities can prepare for them before it’s too late.

Challenging stereotypes for environmental progress

Our work examines how traditional gender roles shape sustainability attitudes. For example, pro-environmental behaviours like reducing consumption or using reusable products are often coded as “feminine” which can discourage some people from adopting them.

Understanding these barriers helps us design more inclusive sustainability campaigns.

Why it matters

Climate change, resource scarcity, and environmental disasters are some of the biggest challenges facing humanity. But how we think about, interact within, and experience our world can shape a more sustainable future.

At Essex, our psychological research helps create tools that build public trust, shift behaviours, and inspire global action, one decision at a time.
