Carbon intensity and how BAM measure progress

Carbon Intensity

8-minutes to read

As well as measuring our actual footprint and making a comparison year on year, we also look at our carbon intensity.

This can be a more meaningful comparison because it shows our carbon emissions per £revenue, or per unit of production. This means it’s not impacted by business growth.

Our overall carbon intensity fell from 0.38kg/£revenue to 0.23kg/£revenue from 2019 to 2020.

However, we also look at the carbon intensity of every area of our business individually and measure it against the most meaningful unit. So, for example, if we’re looking at the carbon emissions of our staff commuting, we’ll measure the carbon emissions per member of staff. This gives us a true measure of how our staff commuting emissions have increased or decreased per employee. We can then identify what we’ve done well and do more of it. We can identify what we haven’t done well and address it.

UK offices and warehouse

2019 2020 % increase or decrease
Carbon emissions 18 tCO2e 21 tCO2e 17%
Carbon intensity 462kg carbon per employee 412kg carbon per employee -11%

Our emissions increased due to warehouse expansion and more employees. Our carbon intensity reduced because 100% of our London office and 20% of our warehouse energy came from renewable sources. Additionally, energy use was lower in the offices as staff worked from home during the pandemic.

Our carbon emissions have gone up due to growth – we sent more orders – and from an increased use of air freight, due to uncertainty around Covid-19. The carbon intensity has also gone up although less significantly. This is because growth has been removed from the intensity number, so it is reflecting the actual increased carbon emissions from our business activity, the air freight.

Staff commute

2019 2020 % increase or decrease
Carbon emissions 32 tCO2e 42 tCO2e 31%
Carbon intensity 821 kg/employee 824 kg/employee 0.4%

Our footprint increased as we had more warehouse staff and they needed to drive to work during the pandemic. The carbon intensity number shows that this increased volume of drivers was offset by the number of staff who were working from home. We’re keen to be back in the office but also committed to supporting staff to work from home more and to supporting their use of lower impact modes of transport when they do commute.

Business Travel

2019 2020 % increase or decrease
Carbon emissions 17 tCO2e 1 tCO2e -94%
Carbon intensity 436kg/employee 20 kg/employee -96%

We couldn’t fly for factory visits this year – seeing our supply chain for ourselves is essential so we’ll resume that work when we can. We couldn’t fly abroad for photo shoots either and so we had to get creative – we’re delighted with the results. We can now redefine which flights are 100% necessary and cut any flight that isn’t. The carbon intensity fell more than the emission because this cut in carbon was achieved despite employee numbers growing.

Raw material, fibre, fabric and garment production

2019 2020 % increase or decrease
Carbon emissions 2078 tCO2e 2582 tCO2e 24%
Carbon intensity 3.7 kg/unit sold 3.7 kg/unit sold 0%

We produced more this year increasing our emissions. Our carbon intensity or emissions per unit stayed the same. We expect the intensity to reduce next year once we’ve measured the impact of activities like switching our polyamide to recycled polyamide.

Customer Use

2019 2020 % increase or decrease
Carbon emissions 907 tCO2e 1126 tCO2e 24%
Carbon intensity 1.6 kg/unit sold 1.6 kg/unit sold 0%

Customers bought more this year so our emissions increased. Carbon intensity remained the same. We base customer use on 50 washes at 30 degrees and as we don’t anticipate changing that assumption, these numbers are likely to stay the same.

An increase in carbon emissions because of growth is still an increase in carbon emissions. We recognise that our growth is in part because consumers are choosing sustainable fibres over the alternatives. Showing carbon intensity simply allows us to identify whether the actions we are taking to reduce emissions are successful. Our goal is to be net zero carbon by 2030.
