The Big Positive Weekend 2014 – The Oracle, WestQuay, Cabot Circus, Centrale, Brent Cross, Highcross, Bullring, Silverburn and Union Square

The Big Positive Weekend is a series of weekend events designed to support collaboration between consumer brands and bring sustainability engagement to the masses.

Sustainability. Campaign Creation. Consumer Communications. Retailer Engagement. Community Engagement. 


The brief

Design an engagement activity that utilises the powerful engagement platform presented by Hammerson’s shopping centre portfolio.

What we did 

Created a cross portfolio consumer engagement campaign – The Big Positive Weekend. The 2014 event reached 2.4 million and inspired over 216,000 actions.

The campaign provides a platform for collaborative retailer communications on sustainability. The first outing in 2014 brought together six consumer brands – Renault, Nationwide Building Society, E.ON, H&M, SEALIFE – in a nine week series of events from Southampton to Aberdeen.

The Big Positive Weekend is returning for 2016. A new look, a new theme – the conscious consumer. For more information on the opportunity get in touch hello@coriandercows.co.uk

"The consumer’s realisation of how much positive change you can drive with purchasing decisions is a defining moment in the shift to a more sustainable lifestyle. The Big Positive Weekend is designed to create many such ‘moments of truth’, whilst introducing products and services that fit the bill, in the very environment where action can immediately be taken."

Donna McKitterick, Director, Coriander Cows

The outcomes

Positive Places Sustainability Framework - Hammerson Plc

An evolution and re-launch of the sustainability framework for FTSE 100 Real Estate Company Hammerson with stakeholder and employee engagement to raise awareness.

Sustainability. Communications Strategy. Brand Messaging. Campaign Creation. Employee and stakeholder Communications.


The Brief 

To create a new communications framework for sustainability within Hammerson and to deliver key initiatives to raise awareness both internally and externally.

What we did

A new sustainability vision was developed – to create places that deliver positive social, environmental and economic benefits. 

Five core Positive Places commitments were outlined.  The commitments offer a quick insight into Hammerson’s deeper strategy and provide a clear communications framework for all activities across the group portfolio. 

A programme of employee and stakeholder engagement initiatives is underway to raise awareness of the commitments and facilitate their adoption at the shopping centre and retail park level. 

Key engagement activities include: 

  • The creation of a dedicated website - sustainability.hammerson.com, to communicate stories, data and strategic direction to investors
  • A new Positive Places display in Hammerson's retail showcase - a new innovation space with Hammerson's head office
  • A series of 3D cubes used to launch the new commitments at the BCSC Conference 2015

“Donna is an excellent sustainability communications and behaviour change specialist. She has delivered a number of complex projects for me at Hammerson providing great creative and strategic input as well as leading on project delivery. Highly recommend.”

Louise Ellison, Head of Sustainability, Hammerson Plc

The Butterfly Bank Volunteering Campaign - Hammerson Plc

The Butterfly Bank is an engagement platform co - created by Coriander Cows. It aims to inspire, reward and report on volunteering, community engagement and sustainable behaviours. We joined up with Hammerson in May 2014 to bring butterfly banking to employees across the Hammerson portfolio, including two offices and nine shopping centres.

The Butterfly Bank. Employee Volunteering. Charity Partnerships. Sustainable Behaviours. Employee Engagement. 


The brief

Hammerson's volunteering policy gives every employee three paid days of volunteering per year.  In previous years volunteering uptake has been fairly restricted, with most activity happening on the annual community day when up to 300 employees head out for one day. Hammerson are keen to drive uptake of the full volunteering allowance. 

What we did 

Hammerson joined up with Coriander Cows to utilise The Butterfly Bank engagement platform and concept. 

The Butterfly Bank was co-created by Coriander Cows to offer clients and partners an innovative new employee engagement tool.  

It's simple, we turn volunteering opportunities, new behaviours and sustainability initiatives into 'bankable' actions.  Employees can record their activity and bank virtual butterflies.  A clear reward structure is used, and when a target number of butterflies are banked a community investment or community project is delivered.

More on The Hammerson Butterfly Banking Challenge 

In May 2015, employees were set the challenge to bank 100,000 butterflies by the end of 2015, through volunteering and positive daily actions such as walking to work and buying organic.  

Hammerson had three key objectives.  Here's how we delivered on them: 

1) To make Community Day administration easier

This annual event sees nearly 300 employees volunteer on the same day. The Butterfly Bank platform enables employees to create an account, and from then on they can sign up to volunteer activities throughout the year with ease. This means the burst of engagement for community day builds a foundation for the year ahead. Their details are moved onto sign up lists, easily provided to volunteer partners. They can withdraw and see spaces counting down. 

“The Butterfly Bank made community day promotion and sign up much faster and easier to manage. Plus, it has meant we can continue to promote volunteering across the rest of the year and reward behaviours we need to become a more sustainable company”.

Louise Ellison, Head of Sustainability, Hammerson Plc

Some stats: Community Day and The Butterfly Bank was launched at 5pm – 71 signed up and had booked their activity by 6.30pm. By lunchtime the next day, 120 had signed up. Within 3 days 222 days were booked.

2) To bring centre teams and office based teams together

Hammerson has teams across the UK based in shopping centres and retail parks. They were keen to both showcase what different centres were doing, to support involvement in community day at centre level and to encourage staff from across the group to join a different team in a different location for their volunteering. The platform brought together all community day opportunities in one place. It enabled London based staff to head out and join centre teams for their volunteering activity. Previous community day was arranged by the local centre teams and not communicated with the rest of the group until after the activity had taken place.

3) To encourage take up of the 3 days of volunteering on offer to all Hammerson employees

By utilising The Butterfly bank, employees can now visit the platform throughout the year to find new opportunities with our charity and local partners. 

We have created five bespoke butterfly banking themes for Hammerson that reflect key strategic areas for them. 

Employees are rewarded with virtual butterflies for each activity banked and regular recognition activities help to reward those leading the way.

Awards designed and delivered in October 2015 celebrated activity across the company and the fact that Hammerson employees met their challenge 3 months early. A new challenge has been launched.

you pledge, we plant – Nationwide Building Society

Consumer engagement activity promoting Nationwide’s sustainability commitments including the creation of woodland right here in the uk. Delivered as part of The Big Positive Weekend 2014, over 400 pledges were made by the public, with over 7 hectares of woodland planted in Hyde Dorset.

Sustainability. Conservation. Brand Messaging. Campaign Creation. Consumer Communications. Project Management.


The brief 

As the headline partner for Hammerson's Big Positive Weekend in 2014, Nationwide Building Society needed an interactive campaign that would promote their sustainability commitments. 

What we did 

We worked with Nationwide and their internal creative team to identify key messages for the consumer.  We identified Nationwide's plans to create new woodland areas in the UK as the core message to promote as we believed this would provide an emotional hook and a great opportunity to create a sensory experience for our shoppers with the creation of a woodland set. 

Shoppers were invited to take part in 'you pledge, we plant'.  They were introduced to four simple behaviours they could adopt that would help to protect our woodland.  Guidance and information was provided to help them adopt these behaviours.  They were invited into our woodland scene to make a personal 'photographic pledge' using our photo booth.  They could share their pledge instantly with friends and family. 

For every pledge made, Nationwide planted a tree - over 4000 trees were planted as a result of Big Positive Weekend pledges creating 7 hectares of woodland. 

"Nationwide is pleased to have been a headline partner for The Big Positive Weekend. It welcomed the opportunity to take our sustainability messages into the heart of the UK via the roadshows as we reached many different parts of the country. The campaign really captured the imagination of passers-by and helped us to promote our agenda. Nationwide volunteers enjoyed visiting the variety of local shopping centres to help people make their pledges to protect UK woodlands. We engaged with a huge 4,000 shoppers as they made pledges and because of this, over 4,000 trees have been planted in Dorset."

Lynn Forrester, Sustainability Manager, Nationwide Building Society

The Butterfly Bank - A new engagement approach

A platform and concept designed to make employee engagement on sustainability and community investment deeper and more rewarding.

Employee Engagement. Web Platform. Sustainable Behaviours. Community Investment. Recognition and Reward. HR. 


What is The Butterfly Bank 

An engagement platform and concept designed to help you inspire, reward and report sustainable and community behaviours.  With The Butterfly Bank you can: 

  • Mobilise employees, members, customers, suppliers or communities to take social and environmental actions, accelerating the journey to a more sustainable way of living and working
  • Launch or increase volunteering with our volunteer module where people can find, sign up to and track volunteering hours
  • Increase uptake of company driven activities such as the adoption of a new travel policy or recycling
  • Increase awareness of your company ethos and sustainability goals
  • Gain insight into your audience; what they like to doand what messages they respond to, making future campaigns and engagement more relevant and inspirational
  • Help build a great place to work in your company with an interesting new employee benefit

How it works 

The platform 

We'll work with you to shape the platform and communications to your needs in four easy steps. 

  1. Open a branch of The Butterfly Bank: It all starts here. Open your own branch of The Butterfly Bank and invite employees and/or customers to open an account.
  2. Set your Butterfly Bank Challenge: For every action people take, they’ll bank virtual butterflies. Inspire action with a clear challenge. A target number of butterflies to bank and a clear reward. We’ll help you to shape a community based reward that helps tell your story. It might be a new sensory garden for local children or the creation of a real butterfly bank to support local wildlife.
  3. Shape ways to bank butterflies:  Identify actions you wish to promote, from volunteering to recycling, or the adoption of new internal processes. We’ll turn them into bankable actions. 
  4. Use our reporting suite to create personalised reports:  You can report on volunteer hours, positive actions taken, behaviours adopted and more.  Plus, shape how you'll use our league tables to recognise those leading the way. 

Why it works 

It builds on personal passions and values: The line between home and work has become increasingly blurred over the past few years, with personal values playing a greater role in employer choice and a focus on the health and wellbeing of employees. We help an organisation to harness this new relationship with their workforce. With The Butterfly Bank, we set new behaviours and activities in the context of the things people personally care about. We create links and touch points that go beyond the borders of the organisation, with people’s personal passions and values driving activity.

It brings together community investment with engagement activity: We bring together community investment/donations with engagement activities. This is rare in companies, as the two are often delivered separately. We harness the corporate donations to drive new behaviours amongst employees by directly linking activity with funding in a simple and visible way.

It facilitates the capture and reporting of behaviours and volunteering: We are designed to make reporting as simple as possible and that means you can feedback what areas are most popular and which teams are most engaged and reward these activities. Plus, you can see which communication campaigns work best and shape future communications accordingly.

Feel Good Friday - Hammerson Plc

Designing an annual day of employee engagement activities designed to raise awareness of sustainability and celebrate health and wellbeing.

Health and Wellbeing. Sustainability. Employee Engagement. Campaign Creation. HR. 


The brief

Every year Hammerson provides employees with an environmental awareness day. For 2014, they wanted to embrace a wider remit for the awareness event, encouraging health and wellbeing amongst employees. 

What we did 

We helped to develop Feel Good Friday, a day of activities held at their head office.  The desire for the day was to create a feel good factor for employees. In order to do this we helped to develop the agenda and the campaign to drive engagement and uptake of the activities.

The day was developed around three core areas for developing health and wellbeing: 

  • Doing good feels good - easy ways to protect our natural environment, including a mini version of the Nationwide you pledge, we plant campaign designed for The Big Positive Weekend. 
  • A little alternative therapy - a little chance to taste some alternative therapies available. 
  • Healthy equals happy - a series of activities designed to improve fitness and nutrition


Over 50% of employees gave the event 9 or 10/10.  The remainder gave it 8/10.  

The event was so well received that it is returning for 2015, extending to Hammerson's Reading office giving employees the double the opportunity to feel good. Plus, we are extending activities to include nutrition and personal training plans, giving employees clear guidance for health and wellbeing going forwards.

"The day was fantastically prepared and really well organised. I would love to see it happen again next year."

The Natural Childhood Summit - National Trust and Ethicore

Coriander Cows worked with Ethicore to design a multi stakeholder summit event that brought together 150 key players in the fields of conservation, health and child welfare.

Stakeholder Engagement. Event and Workshop Design. Conservation.


The brief

The National Trust, Play England, NHS Sustainable Development Unit and RSPB engaged Ethicore to design and facilitate the launch of a new initiative to reconnect children with nature.  National Trust wanted to explore the potential for collaboration with other organisations in response to the natural childhood report produced in 2012. 

What we did

As an associate of Ethicore, Donna from Coriander Cows got involved in creating and leading the Natural Childhood Summit for The National Trust. The day brought together community leaders, charities, local government, corporate partners and academic experts to build consensus around action needed to give every child the opportunity to form a personal connection with the natural world.

Coriander Cows helped to develop and lead a day of workshops designed to identify shared goals which could form the basis of any coalition to reconnect children with nature.  As a team we..

  1. Developed a playful environment bringing the outdoor in
  2. Designed an innovation process to empower partners to innovate
  3. Facilitated a process and packaged the results to inspire action.

As well as lectures from leading players, a series of activities were run in smaller groups to elicit key goals, ambitions and targets for each stakeholder. Disruptive innovation design techniques were used to get stakeholders to consider their plans for the year ahead and how these could be adapted to increase the potential for reconnecting children with nature.


The summit led to the development of a multi organisation task force with a manifesto co created by all stakeholders at the event.

"Ethicore brought new insight and an innovative approach to stakeholder engagement - I recommend them highly!"
Helen Meech, Assistant Director, Outdoors and Natural Engagement, The National Trust


The Natural Childhood Report highlighted a growing problem with nature deficit disorder and a detachment from our natural environment. You can find the report here: The Natural Childhood Report, The National Trust and Stephen Moss.
