GAP’s tips on how to build a Sustainability Culture in your company

As the urgency of climate change and biodiversity loss becomes more apparent, companies are increasingly recognising that a commitment to sustainability is no longer optional, but essential.

Many companies have realised that the best way to mobilise the creativity and insights of their employees is to set up a ‘Green Team’, a group of employees who lead the charge on environmental actions within their company. 

To help companies make the most of their Green Teams, GAP has published a set of Top Tips for Green Teams.

(Click here to read our tips).

Green teams – groups of employees within an organisation who voluntarily come together to plan, implement and advocate for sustainable practices in the workplace – give employees a way to take part in something meaningful. Studies (like this one by IBM and this study by Deloitte) show that a majority of employees and job seekers want their employers to be involved in climate efforts. Green teams allow employees to take action on values they care about. 

GAP’s approach to sustainability emphasises “experimentation” – giving employees space to test out their ideas in a supportive environment. Green Teams can provide such a space, can boost morale and promote a shared sense of purpose at work.

How to Avoid Common Pitfalls

Setting up a green team comes with some challenges. Here’s how to avoid the most common ones:

    • Stay Clear of Greenwashing

      Avoiding “greenwashing” means focusing on sustainability initiatives that have a genuine impact on environmental issues, rather than superficial actions that might look good but don’t actually contribute to long-term change. While small actions, like removing single-use plastics in the office, can have value, they should be part of a broader, more impactful strategy.
      For green teams, this means aiming for substantive projects such as reducing emissions across the supply chain, improving energy efficiency in operations, or cutting down on waste. 

    • Get Management Support

      Without backing from leadership, Green Teams may struggle to get resources and authority. Showing managers the financial and environmental benefits of green team initiatives can help secure their support and resources.

GAP has several tips to help green teams reach their goals effectively. Have a look at our top tips for Green Teams here.

How GAP has developed these tips

These tips are based on the lessons we have learned from our programmes, and from academic research: that psychology matters when it comes to climate and biodiversity action. 

Many employees may feel strongly about climate action, but they may find it difficult to change their own habits (known as the “intention-action gap”). Other people may feel less urgency or responsibility to act on climate change when they perceive it as a distant issue, affecting other places, future generations, or people outside their community (known as “psychological distance”). Similarly, people often resist climate solutions they find too disruptive or inconvenient to their lifestyle, even if they recognise the need for change (known as “solution aversion”)

Green teams can help overcome these barriers, by providing clear, achievable goals that make climate action feel manageable and meaningful in a work context. 

By focusing on specific, impactful actions, such as energy-saving practices or waste reduction, green teams can make sustainability goals tangible and approachable for employees, helping to reduce the sense of overwhelm that often comes with climate action.

People are strongly influenced by the behaviour and attitudes of others around them. When sustainable practices are seen as the standard within the company, employees are more likely to adopt and support green initiatives. Effective green teams offer practical, incremental actions that feel achievable and manageable, reducing resistance and encouraging broader participation. Similarly, Green Teams can promote green actions and norms, and help make climate action more visible within the company. 

To mobilise employees effectively, a company Green Team can focus on a few high-impact areas that resonate with employees and are practical. 

Here is our list of potential areas of focus for corporate Green Teams:

1. Energy Conservation and Renewable Energy

    • Energy Efficiency: Identify those areas where energy can be reduced by upgrading to energy-efficient light, optimising heating and cooling systems, or encouraging better use of electricity.

    • Switch Over to Renewable Energy: Recommend shifting to renewable sources of energy such as solar or wind. Make the workers aware of what change might bring.

    • Empowerment to energy saving: Engage employees in energy saving by sensitising them on the need for switching off lights, equipment, and putting computers to sleep during after hours.

2. Waste Management

    • Reduce, Reuse, Recycle Campaigns: Help reduce waste by providing clear instructions on recycling, and ensuring compost bins and recycling bins are clearly marked and well placed. Optimise Office Supplies: Reduce paper use and single-use plastics by encouraging digital workflows and utilising supplies that can be refilled.

    • Waste Reduction Competitions: Consider rewards or incentives for employees or departments that consistently recycle properly or come up with ways to reduce waste. Introduce friendly interdepartmental competitions or monthly goals monitoring which team can do the most to reduce waste (like GAP’s digital waste challenge). 

3. Green Transportation and Commuting

    • Provide incentives or a commuter benefits programme for carpooling, cycling, walking or using public transportation.

    • Work-from-home policy: Flexibility to work from home could mean a decrease in the production of transportation emissions.

    • Electric Vehicle Infrastructure: EV charging points provided within the company’s car park, among others.

4. Green Purchasing Practices

    • Source Eco-Friendly Products: Try to find environmentally friendly sources and ethically produced materials for your office supplies and equipment.

    • Local Sourcing: Give preferential treatment to local suppliers, or suppliers who are certified for environmental considerations.

5. Climate Education and Employee Engagement

    • Contact GAP for suggestions on how to organise events, training sessions or seminars for employees on climate and biodiversity issues.

    • Encourage employees with ideas of sustainability at work, even going as far as initiating and leading green initiatives. Friendly Eco Challenges may also be staged to generate enthusiasm around certain objectives.

6. Protection of Biodiversity and Natural Resources

    • Plant native species, if available, in all exterior spaces. It could be anything extending from a rooftop garden to green walls.

    • Provide opportunities for employees to get involved with habitat restoration activities, including tree-planting events and clean-up events in parks.

7. Sustainable Building Operations

    • Strive for certification to attain building sustainability standards.

    • Promote water-saving behaviour in the organisation; collect rainwater; install Low-flow water systems in your buildings; 

    • Encourage natural ventilation or the use of energy-efficient heating systems.

8. Build A Green Culture

    • Incentives for Green Behaviour : Think of gift cards, extra paid days off, or recognition for those employees that continuously provide leadership and inspiration associated with sustainability. 

    • Green Ambassadors: Choose excited and energetic employees to take on roles as “Green Ambassadors” that will champion sustainable practices within their teams, to inspire others. 

    • Allow employees to monitor progress regarding sustainability efforts within the company as a whole, so they may set benchmarks and understand how their individual efforts will contribute to the big picture.
