Since announcing the new strategy at the start of 2017 we have been active on all fronts to improve the business. In communications to date the focus has been on our strategy and progress, so as to not dilute the message. We have not been very vocal about our sustainability initiatives, except for stating that we are well on track to meet the minimum C-label EPC energy certificate requirement by 2023.

In 2018 we started to work on a future proof ESG programme. As NSI is a small organisation we have used an external advisor to provide the relevant support and manpower to help put together a detailed and ambitious programme.

Everyone at NSI has been involved in establishing the ESG programme. We have considered the UN Sustainable development Goals and have engaged with external stakeholders to come up with what we believe is a well-rounded programme. The three overarching sustainability priorities we have identified are: Future Proof Buildings, Energy & Carbon and Health and Well-Being.

Our sustainability ambitions clearly go much further than scoring on government-imposed minimum energy labels. To measure and judge our programme and impact we have decided to focus on the GRESB benchmark. We will publish our first GRESB score in 2019.

This will provide us with a base score and allow us to set a clear and realistic path for the years ahead, in line with our ambitions. The team fully recognises that this programme and our participation in GRESB will take time and effort to fully implement and see effects, but it is a way of working that we have already fully embraced. Our recent initiatives reflect this. Over the past four years we have fully renovated around 80,000 sqm of office space, including a full upgrade of the lighting with 25,000 LED units with motion sensors. We have also started to minimise gas usage and over 40% of the portfolio by sqm is using sustainable district heating, heating pumps or ATES systems. We are committed to increasing the use of sustainable solar energy but due to our recent disposals only 2.4% of our electricity usage is currently generated this way.

The following SDGs are currently most relevant to our ESG programme, and reflected in our overarching priorities:

The resulting materiality matrix plots specific topics by theme,

point of view. The materiality matrix was completed by 65% of
