Carbon footprinting is currently not an exact process across all areas, however Greenredeem do have a series of tried and tested methods of measuring improvements, which include actual and estimated data readings. In collaboration with our partners and utility providers, we have established different ways to track and monitor all interventions, but furthermore we are continually developing and adopting the most up to date and accurate processes and technical solutions.

Our approach to determining the carbon footprint of positive environmental action:

  1. Identify and establish baselines that allow us to track performance
  2. Educate and interact with residents through content we know engages them
  3. Attribute a carbon saving to the environmental improvements

Identify and establish baselines to track climate change progress

Whatever the climate change initiative, we will establish baselines from which we can measure performance. For example, the amount of water a resident uses at home would be based on actual meter readings and compared to historical baselines. We monitor and track a resident’s engagement with campaign content and then measure the direct impact on their actions e.g. reductions in water.

Helen, 24, Tower of Hamlets

For this example, we look at Helen a London resident. We can see compared to her historical baseline she has saved 2,625 litres of water in July. What has triggered this and what influences do we need to consider?

As the chart highlights, seasonality & other key events had an impact on the average network usage of water. These are key consideration which influences the content served to residents.

All of Helen’s interactions with campaigns are recorded and monitored via our Digital Behaviour Change Platform, through which we build an understanding of her individual actions. This allows us to further personalise her experience and automate communications based on her interactions, building an eco-system that fosters continuous engagement.

Through these insights we determined the most effective and relevant way to communicate to Helen, delivering tactical messages to achieve the most impactful and sustained results.

Helen’s engagement in water-saving content

Focussing on July in isolation, Helen engaged with 8 activities in total, which contributed to the direct action of water-saving being achieved. New content i.e. blogs, articles, quizzes & pledges were served to Helen on a weekly basis to maintain her interest and momentum, tailored to Helen’s profile.

Associated carbon footprint saving

As an example of our approach, here we look at the carbon impact of some of Helen’s actions in July:

  • Reducing her shower time from 10 minutes to 4 minutes (further to campaign content / pledge, which motivated Helen to act)
  • Reducing her total water usage
Electricity saving based on the usage from a typical 8kW electric shower
 June July 
Shower time 10 mins4 mins
CO2e usage 500g 200g
CO2e saving per day  300g 

Helen’s new behaviour of showering for 6 mins less per day will save 109.5kg of CO2e per year.

Water-saving impact based on 1 litre of drained tap water = 1.06g CO2e
Total water saved  2,625 litres 
CO2e saving July   2.8kg 

Helen’s new behaviour of reducing her water consumption will save 33.6kg of CO2e per year.

In next week’s blog post we explore the benefits of linking different climate change topics to increase engagement and increase carbon reductions.
