The time for action is now.

Using a reusable shopping bag, switching to a renewable energy provider, video conferencing instead of flying - all of our actions have an impact on our planet.

Your employees make their pledges; Do Nation automatically measures their impact in terms of carbon, water, and waste saved. We take into account a user's previous behaviour, and follow up after two months to find out how they got on.

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

Cycling to work, eating less meat, reading up about sustainable innovations in your industry, and simply being part of a community of people taking positive action together. They're all things that can make people feel better - physically and mentally.

And employees who feel better tend to work better too.

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

By engaging staff in sustainability, they're more likely to factor it into their own work – unlocking significant innovations and commitments. For example, after pledging to use a reusable water bottle himself, 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 doing this, obviously, but it's a nice side effect. Whether by 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 a lot harder to attach a price tag to, but our sense is that it's a big one.
