1. Skanska UK PAS2080 and the carbon process
Welcome & thanks for joining us …
In this presentation, we’ll explain:
What impact do buildings have on climate change?
What Skanska UK’s goals are
Why supply chain emissions are so important
What can we all do collectively to reach those goals

Environment and Carbon Manager – Infrastructure

2. Why low carbon?
“ The defining environmental issue of our generation is accelerated climate change.
“ We are putting carbon emissions reduction where it belongs: at the front and centre as one of the largest challenges the construction industry faces.”
Gregor Craig, President and CEO, Skanska UK
Skanska UK’s President and CEO, Gregor Craig, says that accelerated climate change is the defining environmental issue of our generation.
He says that Skanska UK is taking an industry-leading position on reducing carbon emissions: we have set a target of net-zero emissions by This will include all the emissions produced by our supply chain, from their work on our projects.
Greg says that reducing emissions is one of the most important challenges the construction industry faces.
He believes it should be an industry priority to reduce emissions, and that all construction companies should be aiming for net-zero emissions – including the supply chain.
He says the sector also faces significant efficiency and productivity challenges, and that there is a body of evidence that links carbon with cost.
Greg says that delivering better, and cheaper, solutions for our customers is another compelling reason to take carbon reduction seriously.

3. Net-zero carbon by 2045 Skanska’s target: including our suppliers
This is our main target.
We aim to be carbon-neutral, with net-zero emissions, across our portfolio of projects by 2045.
This includes all the supply chain emissions produced from work on our projects, during construction or maintenance work.
We think that this is an achievable goal.

4. Skanska UK direct emissions plus supply chain emissions
The whole story
Skanska UK direct emissions plus supply chain emissions
When we add in our estimate of supply chain emissions, it shows our real impact is around 10 times that.
Here is a key figure to remember:
Between 2010 and 2018, when we include our supply chain emissions, Skanska UK has emitted over 3 million tonnes of carbon.
That’s equivalent to burning around 18,000 acres of forest, that’s an area 8 times the size of Richmond Park.

5. PAS2080 and carbon management
Creates a strategy for carbon management across the life of a project
To deliver the benefits the whole value chain should be aligned and consistent in their approach
PAS2080 provides the framework for a carbon management process

8. Carbon/cost baseline
Using the cost model we calculate the carbon equivalent to use as a baseline for carbon reduction targets
Identify carbon hotspots and big wins
Skanska UK believes it’s important to tell the whole story, when it comes to carbon emissions.
Let me show you the size of the difference for Skanska UK.
Looking back to 2010, you can see the carbon emissions that we’ve traditionally reported, from our own offices and cars.
You can see it fluctuates at around 35 thousand tonnes of carbon every year.
