Sustainability isn't just about carbon. Most of the actions listed on Do Nation have wider impacts too, like improving wellbeing. In fact, 68% of users report improved health or wellbeing.

Cycling to work, eating less meat, growing your knowledge around sustainable innovations in your industry, and being part of a community of people taking positive action together. These can make us feel physically and mentally better.

Employees who feel better, work better too.

Nothing gets people talking like action. On average, each person talks to six people about their pledge and the programme. These conversations drive awareness and build a culture of sustainability.

People who engage in sustainability are more likely to factor it into their own work, which leads to significant innovations and commitments. For example, after pledging to use a reusable water bottle, a Network Rail director committed to phasing out the use of 100,000's water bottles on their sites.

It's not the main reason you're here but it's a nice side effect. Whether reducing travel costs, landfill taxes, or energy bills - behaviour change saves money. Simple.

In fact, the Carbon Trust estimates that workplace behaviour change programmes reduce energy costs by 10% on average.

Happy, healthy, and proud employees are also more productive and loyal. That's valuable too.
