Danfoss Achieves 74% Carbon Emissions Reduction in Expansion Valve Production

In a step towards sustainability, Danfoss has significantly reduced carbon emissions in the production of thermostatic expansion valves (TXV). Using low-GWP refrigerants in the valve bulb, Danfoss has cut emissions by 74% compared to 2019, with an ambitious goal of reaching an 85% reduction by 2030. This initiative not only supports Danfoss decarbonization targets but also aids customers in their own sustainability efforts. 

Walking the talk: How we’re accelerating our decarbonization journey with low-GWP refrigerants

In 2020, Danfoss took a significant step forward in our decarbonization journey. We committed to science-based targets, which the Science Based Targets (SBT) Initiative validated and approved in 2022. Those targets are to reduce our absolute scope 1 and 2 GHG emissions by 46.2 % by 2030 from a 2019 base year, and our absolute scope 3 GHG emissions by 15% within the same timeframe. In addition to that, we’ve committed ourselves to decarbonizing our own operations by 2030 and reducing our scope 3 upstream emissions by 25% by the same year.

Reaching these targets requires rethinking the way we operate across our entire value chain. We’ve developed a three-step approach to help us get there: reduce, re-use and re-source.

“In 2015, when the EU passed the F-gas regulation, we put together a team to identify low-GWP refrigerants that we could use in our TXV valves,” explains Lasse Nicolai Langmaack, Product Director, Mechanical Expansion Valves. “Each TXV valve holds only a small amount of refrigerant gas. However, as one of the largest players globally, producing in large quantities, even small reductions have a significant impact on our overall CO₂ emissions.”

The team spent hundreds of lab hours to find the right low-GWP refrigerant mix, and that investment of time and resources has paid off.

The strides Danfoss is making in decarbonizing its products benefits customers as well.

“Decarbonization is really a joint initiative across the entire value chain,” states Johanna. “Danfoss wants to be our customers’ preferred decarbonization partner, and by reducing the carbon footprint of our expansion valves, we help our customers on their journey towards a sustainable future.”

Lasse agrees and points out that the use of low-GWP refrigerants is just one area where the TXV valves reduce customers’ carbon footprint. “Our valves maintain a constant low superheat, which enables the refrigeration system to run at its most energy efficient way,” he says.
