Sustainability Signals

Twice a year, Deloitte explores how environmental awareness and related behaviors are shifting by surveying roughly 20,000 respondents in approximately 20 countries across three main spheres—home, workplace, and civic participation. The results can help leaders track how environmental sustainability and related issues are impacting daily lives, yielding important signals about how consumers, employees, and communities are changing over time. We invite you to explore the interactive data dashboard and our growing collection of reports.

Sustainability attitudes and beliefs

A stable majority of global respondents see climate change as an emergency and believe that it is caused by human activity. Experience, in part, seems to drive attitude: Those who have recently experienced extreme weather events are more likely to think it’s an emergency. This is particularly prevalent among those between the ages of 18 and 34, who are also more likely to report feeling anger, sadness, hopelessness, fear, and guilt about climate change.

Recent experience with extreme weather events

Deloitte has been tracking respondents’ personal experiences with a variety of extreme weather events since 2021. Increasingly, people around the world report directly experiencing extreme weather. Across the countries surveyed, more than half of respondents said they experienced extreme weather—particularly extreme summer heat—across 2022, 2023, 2024, and early 2025.

KEY TAKEAWAY

Increasingly, people around the world are reporting experiencing shifts in extreme weather. These impacts are likely to grow more frequent and severe in the coming decades.

SELECTED FILTERS

Belief in human-caused climate change

Large majorities of respondents believe in anthropogenic (human-caused) climate change. With some variation, this is true regardless of the demographic. This is consistent with scientific consensus.

KEY TAKEAWAY

How respondents feel about climate change

Our survey asks about a range of different emotions respondents globally may feel about climate change. Younger respondents report feeling strong emotions about climate change, particularly when compared to those over the age of 55.

KEY TAKEAWAY

Our latest data show a steady presence in three of the positive emotions associated with climate change—hope, determination, and curiosity—across all three age brackets.

LEVEL OF AGREEMENT

Belief that climate change is an emergency

The majority of respondents worldwide consistently agree that climate change is an emergency. Globally, that’s true across age cohorts, but there is a pronounced age gap in the United States. Among 18 to 34 year olds, 55% say climate change is an emergency, compared to 48% of those who are 55 years old or older. The percentage of respondents who don’t think it’s an emergency increased during 2023 but has held steady near 20%.

KEY TAKEAWAY

People who say they have experienced a climate event are more likely to believe climate change is an emergency than those who have not.

Personal choices

To gauge the impact of awareness on action, Deloitte’s survey asks respondents about their shopping habits, community engagement, financial decisions, and other personal choices.

Are you changing your personal habits to help address climate change?

Despite a range of other pressures and priorities, most global respondents report changing their personal behaviors to help address climate change. People who think climate change is an emergency are far more likely to report that they have changed their behaviors to address climate change than those who do not.

KEY TAKEAWAY

There is a sizable segment of the population that say they are engaged in personal climate action, suggestion there are opportunities for products and messages that speak to this mindset.

Impact of climate change on relocation decisions

Data suggests that respondents are already factoring climate change into major life decisions. Globally, climate change is factoring into where respondents decide to live, with 50% saying it would be a decision criterion for a future move, and roughly 11% saying they had already or were planning to relocate due to climate impacts. Among 18 to 34 year olds, 66% say reducing their exposure to climate impacts would be a consideration for a future move, compared with just 44% among those over the age of 35.

KEY TAKEAWAY

Organizations that start considering current and future impacts will likely be better positioned to adapt to a hotter, less predictable world.

Climate-conscious investing

Roughly one-third of respondents globally say that sustainability considerations are impacting where they invest their money in some way (such as where they bank or which investments they choose). Tracking changes in this data over time could indicate how interest in climate-conscious investing might be shifting.

KEY TAKEAWAY

While the results do not indicate the size of respondents’ investments, nor what specific actions they are taking to incorporate sustainability considerations into their financial decisions, a notable portion of global respondents are aligning their financial investments with climate action.

Trade-offs for sustainable products

Globally, about half of consumers surveyed by Deloitte since 2021 purchase at least one sustainable product every month. However, sustainable products can come with trade-offs, including perceptions of higher costs, lower quality, or diminished performance. Even with the rise in global climate change awareness, for example, demand for sustainable products has not changed much, and has even slipped a bit over the past few years.

KEY TAKEAWAY

Insofar as price remains a challenge for people making sustainable product purchases, demand is likely to stall if consumers are forced to choose between what’s better for the planet and what’s better for their wallets. Companies that can offer competitive prices many find greater demand for their products than current sales seem to suggest.

Workplace engagement

The third dimension that Deloitte’s survey covers is how respondents’ perceptions of climate change can impact their experiences at work. Engaged employees can lend their skills and knowledge to tackle sustainability-related business problems and opportunities, flag potential issues for leadership, and help catalyze deep organizational change that could help companies achieve their sustainability goals.

Respondents’ perceptions of climate action at work

Among those surveyed worldwide by Deloitte, there has been a decline in the number of people across all regions who believe “[their] employer is doing enough to address climate change and sustainability.” In September 2021, 45% of global respondents thought their employer was adequately addressing climate change and sustainability. Our most recent data shows that, as of March 2025, only 38% continue to think

KEY TAKEAWAY

The results suggest a strong opportunity for employers to do more to engage their employees on this topic, and to understand the impact their actions may have on loyalty and attrition.

Impact of sustainability on respondents’ intent to switch jobs

Among respondents who are employed, about a quarter, globally, have considered switching jobs to work for a more sustainable company. And among job seekers, about a quarter say they will consider a potential employer’s position on sustainability before accepting a job.

KEY TAKEAWAY

Shifts in employee expectations could have a downside for companies that aren’t taking sustainability into account, placing them at a disadvantage in competition for some talent.
