Lindab's emission reduction targets approved by the Science Based Targets initiative
The Science Based Targets initiative (SBTi) is an international framework for climate targets in line with the Paris Agreement's goal of limiting global warming to 1.5°C. After a process of submitting data supported targets, including a long-term net-zero target for external validation, it is now established that Lindab's emission reduction targets have been approved by SBTi.
Lindab will join other pioneers in the private sector, registered and approved by the SBTi, to lead urgent climate action. With a long history of sustainability efforts, Lindab has already implemented activities aligned with these targets. These initiatives include using fossil-free and renewable electricity, installing solar panels at production sites, and expanding the standard product range to include ventilation products made from recycled steel in some markets, among other efforts. Lindab's ambition surpasses SBTi's minimum requirements, and in 2023, these ambitions were even exceeded.
"Lindab has an ambitious climate agenda. Having a third party carefully inspect, validate, and approve our targets in alignment with the latest science marks a significant milestone in our sustainability journey. While Lindab has a long-standing commitment to sustainability, we are now intensifying our efforts to achieve these ambitious targets," says Ola Ringdahl, President and CEO of Lindab.
As an overall net-zero target, Lindab commits to reach net-zero greenhouse gas emissions across the value chain by 2050. In the near term, there is a commitment to reduce absolute scope 1 and 2* greenhouse gas emissions by 56% by 2030 from the base year 2022**. Lindab also commits to reduce absolute scope 3 GHG emissions from purchased goods and services***, upstream transportation**** and distribution, waste generated in operations and use of sold products by 25% within the same timeframe*****. Long-term, Lindab commits to reduce absolute scope 1, 2 and 3 GHG emissions by 90% by 2050 from the base year 2022**.
Lindab also acknowledges the challenges and the cooperation required to achieve the set targets, such as the decarbonisation of the steel industry, taxation on greenhouse gas emissions, fossil-free transportation, and customers' willingness to pay for sustainable products. Lindab looks forward with confidence to doing everything possible, in collaboration with other actors, to overcome these challenges.
SBTi is a collaboration between CDP Disclosure Insight Action, the World Resources Institute, the We Mean Business Coalition, WWF and the UN's Global Compact. In addition to SBTi evaluating and approving companies' targets, the initiative also wants to raise awareness about companies taking responsibility for limiting the effects of global warming.
* Market-based approach.
** The target boundary includes land-related emissions and removals from bioenergy feedstocks.
***Included purchase of direct material.
**** Included in the target are transport between Lindab Group sites and transport to customer where Lindab pays.
*****The year 2022 is considered as a representative base year as operations had returned to normal levels after the pandemic. There were no significant temperature deviations compared to other nearby years, and data for scope 3 is available from this year.
Lindab Ltd - Temperature – cold facts on a hot topic
Well, maybe we exaggerated a bit calling indoor temperature a hot topic, but it’s an important part of the indoor climate when it comes to comfort and productivity. And to feel comfortable is a prerequisite for performing without hindrance. Both high and low temperatures can affect mental ability, work capacity, strength and mobility. This in turn can affect the frequency of accidents, work performance and comfort.
Thermal comfort
In the world of indoor climate we often hear the term thermal comfort. It is defined as “that condition of mind that expresses satisfaction with the thermal environment” in the globally recognized ASHRAE 55 and ISO 7730 standards for evaluating indoor environments. In other words – the situation where people are satisfied with the temperature and do not want a warmer or colder climate.
So, when do we reach that level of satisfaction? There is no exact answer to this question as there is no exact science. It all depends on the occupants age, clothing, health and their highly subjective opinion on what feels good. If a larger number of people are staying in a building with optimal conditions at least 5 percent of people are dissatisfied with the indoor climate. The aim should be to reach as few dissatisfied people as possible. But in general terms, for offices and schools, a suitable indoor temperature in the summer is 23-26°C, in the winter 20-24°C. The fact that it should be warmer in the summer is because the difference between outside and indoor temperature becomes too great otherwise, light summer clothes mean that we would freeze indoors if we did not raise the temperature slightly.
Calculating thermal comfort
Lindabs online calculation tool LindQST Indoor Climate Designer is updated with the method for analytical determination and interpretation of thermal comfort. It uses calculation of the predicted mean vote (PMV) and percentage of dissatisfied (PPD) indexes and the local thermal discomfort criteria DR (Draught Rate). The PMV index predicts the mean response of a large group of people on a 7-point thermal sensation scale, while PPD is directly linked to PMV and estimates the percentage of people who would be dissatisfied with a particular thermal environment. All based on the EN/ISO 7730 standard. Categorization of the thermal comfort calculations are according to EN 16798.
What happens when the temperature is not optimal?
At too high temperatures we get tired and have difficulties concentrating. It can also aggravate any pollution that is already present. At too low temperatures, we find it difficult to do things physically. In general, when there are complaints, the complainant often exaggerates the importance of one single factor, e.g. air temperature. There are actually a number of different factors that may affect the thermal comfort:
Environmental factors
– Air temperature
– Airspeed
– Relative humidity
– The average radiation temperature
Individual factors
– Activity
– Insulation, clothing
Ergonomics of the thermal environment - Analytical determination and interpretation of the thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria (ISO 7730:2005)
