Our Net Positive Objective

OUR NEW POSITIVE PLACES OBJECTIVE IS TO BE NET POSITIVE FOR CARBON, RESOURCE USE, WATER AND SOCIO-ECONOMIC IMPACTS BY 2030

Hammerson is already a sector leader in both environmental and socio- economic performance. But we can do more. 

Our Net Positive ambition formalises this objective. 

“Hammerson taking a leadership role in Net Positive is extremely exciting, not just because of the significant positive impacts this will have from an environmental and socio-economic point of view, but most importantly because it will be able to transform the sector as a whole, by leading the way, showing others who will hopefully follow suit.”

Darren Berman, Lead Director, Upstream Sustainability Services, JLL 

Our Net Positive Areas

We aim to be Net Positive in four areas where we have the greatest material impacts and therefore the greatest opportunities to drive change. 


CARBON: Net Positive for Carbon means emissions avoided exceed emissions generated.

Our carbon footprint calculated on this basis is 192,000 tonnes. This forms the baseline against which we will measure our progress over the next 15 years. In order to first move to zero, then beyond into net positive impacts, we will: 

  • Minimise emissions through efficiency projects such as LED lighting installation, efficient switching systems and good management. 
  • Install renewable energy generating systems on our existing assets and new developments and maximise the use of generated energy on site.
  • Make sure all future developments are designed to minimise operational carbon emission.
  • Purchase 100% renewable electricity for the portfolios wherever possible.
  • Find creative ways to offset remaining emissions, through investment in offsite projects such as insulation of local homes or investment in renewable energy.

RESOURCE USE: Net Positive for Resource Use means waste avoided, recycled or re-used exceeds materials used that are neither recycled, renewable or sent to landfill.

Our operational and development activities generated 123,000 tonnes of waste in 2015, 67% of which was recycled. In order to move to a net positive position we will:

  • Minimise waste generated on our operational assets and maximise the recycling and reuse of waste materials on site.
  • Work with our contractors to minimise construction and demolition waste from our developments and maximise reuse and recycling.
  • Design waste out of our developments during the design phase, reducing resource consumption.
  • Minimise the use of resources that are neither recycled nor renewable through application of our design standards across all areas of work, including fit out.
  • Create innovative ways to offset any raw material use, and any waste sent to landfill. 

WATER: Net Positive for Water means water replenished by external projects exceeds water consumed from mains supply.

In 2015 1.6 million m3 of potable water was used across our portfolios. In order to move to a net positive position we will:

  • Reduce potable water consumption from mains supplies at our managed assets through water efficiency programmes.
  • Minimise water demand at new developments through design.
  • Invest in water harvesting and recycling technologies where possible at our managed assets.
  • Identify and undertake projects that will either replenish water resources or recycle waste water to offset potable water consumption.

SOCIO-ECONOMIC IMPACTS: Net Positive for Socio-economic impacts means making a measurable positive impact on socio-economic issues relevant to our local communities beyond a measured baseline.

In order to set our baseline and shape our plans, we will: 

  • Establish a clear placemaking strategy that reflects the needs of our local communities and delivers this through our asset management and development programme.
  • Set community engagement plans for each asset that address issues identified as relevant to the local community.
  • Set locally specific baselines and measure performance against these.

Our Baseline Data

In order to achieve this ambitious objective, it's vital we have a clear baseline.  Our Environmental and Socio-economic Footprints launched in 2017 provide this baseline and give us valuable insight into the potential impact of our activities.
