Carlsberg Group is one of the world’s largest brewery companies, employing more than 41,000 people and with products available in over 150 global markets.
Selling billions of beers each year, the business has a significant direct and indirect environmental impact. This occurs across several areas, such as: the agricultural production of ingredients; the use of energy and water in the brewing process; and the manufacturing and recycling of bottles and cans.
Over the past decade Carlsberg has made good progress in reducing negative impacts throughout its operations and supply chain.
However, the business still did not feel that it was doing enough given the scale of the challenges the world currently faces. It recognised that increased levels of action would be necessary to deliver on the UN’s globally-agreed Sustainable Development Goals and the Paris Agreement on climate change.
Carlsberg therefore decided to strengthen its sustainability ambitions with targets towards 2022 and 2030. In order to develop these targets and make sure they would be credible, the business wanted to work with experienced, expert partners to provide technical support and practical guidance.
The Carbon Trust was selected to support Carlsberg on the issue of climate change, working closely with the group’s sustainability, utility management and supply chain teams, as well as a number of key suppliers. This involved three particular pieces of work.
The first step was to ensure the company was accurately measuring the end-to-end carbon footprint of its full value chain, incorporating both supply chain emissions and downstream customer use and disposal of products.
Secondly, stretching but achievable targets for emissions reduction were defined, that are in line with what climate science says will be required to limit global warming to no more than 2 degrees Celsius.
Finally, a roadmap was developed that set out how these targets could be achieved.
Value chain footprinting
A critical first step in developing an updated climate change ambition for Carlsberg was the measurement of the global carbon footprint of the business. This is because good quality measurement of emissions underpins the development of successful approaches to reducing them.
By identifying emissions hotspots it is possible to target action on areas of inefficiency, or seek out innovative product and business model solutions to reduce their impact. Accurate measurement also provides a baseline against which progress can be tracked, helping to understand which activities have been most effective.
The Carbon Trust supported Carlsberg by developing a database and emissions calculators, alongside a business intelligence dashboard that helped to highlight insights from the data. An important part of the approach was to make use of company data in its existing formats, to minimise any requirements for new data collection or input from different parts of the group.
The most challenging part of the footprinting process was to quantify Scope 3 emissions. This requires a greater use of estimates and assumptions based on secondary data, which are then used to understand impacts occurring at multiple points both upstream and downstream of the business.
This is an area where the Carbon Trust was able to support Carlsberg with its world-leading expertise, thanks to years of experience in emissions measurement across multiple economic sectors and regions. In particular it was important to understand where emissions arose at different product life cycle stages across various global markets, from the production of raw materials right through to the disposal of packaging.
The tools developed by the Carbon Trust allowed Carlsberg to understand both its total group footprint and the emissions per hectolitre of beer brewed, helping the business determine the full life cycle impact of its products and work to reduce it.
Setting a science-based target
Building on a detailed understanding of Carlsberg Group’s global impact, the next stage in the Carbon Trust’s work was to support setting a science-based target. This involved establishing that Carlsberg’s operational emissions reduction goals were fully in line with what is required to have a good chance of keeping global warming below 2 degrees Celsius above pre-industrial levels.
Carlsberg’s current commitment is to achieving net zero greenhouse gas emissions at its breweries by 2030, which would reduce the company’s total Scope 1 and 2 emissions by 92 percent from 2015 levels. This is supported by an interim 2022 target to cut brewery emissions in half from the same base year, which would reduce the company’s total Scope 1 and 2 emissions by 46 percent.
These targets go beyond the level of emission reductions required for the 2 degrees threshold, and are at a level that would contribute to limiting global warming to 1.5°C, the higher level of ambition contained within the Paris Agreement.
The Carbon Trust sits on the Technical Advisory Group of the Science Based Targets initiative and has worked with clients across multiple sectors to set science-based targets using different methodological approaches. This experience was used to tailor the principles of the initiative to fit with Carlsberg’s internal group targets and metrics, confirming that the company’s goals exceeded the levels of carbon emissions reduction required.
For this target to be recognised by the Science Based Targets initiative, Carlsberg also needed to have measured and put in place goals to reduce Scope 3 emissions. To do this the company made a further commitment to reduce the beer-in-hand value chain carbon footprint associated with its products by 30 percent by 2030, again using 2015 as a base year, with an interim target of reaching 15 percent by 2022.
This target was possible thanks to the value chain footprinting work that had already been completed with the Carbon Trust. This provided a measurement baseline and the business intelligence required to set stretching but achievable goals to have an impact with suppliers and customers.
