Our greenhouse gas footprint
The most meaningful way to measure the greenhouse gas (GHG) impact of our business is to look across the whole lifecycle of our products. Accurate measurement and transparent reporting of our GHG footprint helps us adapt our strategy, set ambitious targets, and assess our progress towards our 2030 halving commitment.
Why do we measure our GHG footprint?
What is the real GHG impact of a business like ours? For many years businesses thought about this question in terms of their own factories, where energy use is easiest to measure and where they had most control.
The direct emissions from our factories are a vital focus for us, and we measure them carefully - but they amount to less than 5% of our total GHG footprint. A much more meaningful picture of our impact comes from measuring across the value chain: from raw materials (primary packaging, secondary packaging and ingredients) to manufacturing, transport, storage at retail and at home, and crucially, consumer use and disposal, which account for over 60% of our total GHG footprint.
Climate change is a principle risk factor for both our business and society at large. For example, temperature increases and extreme weather events (storms, floods, droughts) can drastically raise the cost of raw materials and packaging, which in turn can affect the affordability of our products. Mitigating climate change starts by reducing our own environmental impact, which is why we measure our GHG footprint and track our progress towards halving our GHG impact by 2030.
How do we calculate our GHG footprint?
We've been calculating our GHG footprint across the value chain since 2010, measuring the emissions associated with the lifecycle of a large group of products that are representative of all our 12 product sub-divisions (Beverages, Deodorants, Dressings, Hair Care, Household Care, Ice Cream, Laundry, Oral Care, Savoury, Spreads and Cooking, Skin Care and Skin Cleansing). Our footprint focuses on 14 key countries (Brazil, China, France, Germany, India, Indonesia, Italy, Mexico, Netherlands, Russia, South Africa, Turkey, UK, and the US), which represent around 60-70% of our sales volume.
We calculate our GHG impact annually, both at an absolute level and ‘per consumer use’, which is the GHG impact of our consumers making a single cup of tea or doing a load of laundry. These measurements enable us to see where we are making improvements and where we still have work to do - for example, by innovating new, more energy-efficient products, or by improving our packaging.
Our 2017 GHG footprint
Our absolute GHG footprint is around 61 million tonnes CO2. The GHG emissions of our products are around 46.2g CO2e per consumer use. Since 2010, our GHG impact per consumer use continues to edge up and has now increased by around 9%† since 2010.*
Our 2017 footprint shows reductions in GHG emissions from the increased use of renewable energy in our factories, innovation (e.g. 95% reduction of phosphates from our laundry powders), and portfolio changes (e.g. the market growth of fast-rinse fabric conditioner). However, these GHG reductions have been negated by the acquisition of skin cleansing and hair care brands which sell products with above-average greenhouse gas impact per consumer use. These products are being used by consumers while taking heated showers and baths.
Our analysis shows that manufacturing and distribution represent less than 5% of our total GHG footprint, while consumer use accounts for over 60%. The product sub-divisions that make the largest contribution to our GHG footprint are those where consumers need heated water to use our products, for example showering, washing hair and laundry.

Assurance of our GHG performance measure
In 2017, PwC have carried out independent assurance of our latest GHG performance measure for the fourth year. Please see Independent Assurance for more details of our assurance programme.
* Our environmental targets are expressed against a baseline of 2010 and on a 'per consumer use' basis. This means a single use, portion or serving of a product.
