Mapping Wedge Group's value chain emissions 

​​

Wedge Group Galvanizing is the UK’s largest hot dip galvanizing business, with 14 plants located across the country. The company has established a clear Sustainability Commitment, underpinned by the triple bottom line of People, Planet, and Profit.

​

Wedge has reported on its Scope 1 and 2 emissions for several years, to meet mandatory compliance requirements and as part of its wider commitment to achieving Net Zero. As a natural next step, Wedge engaged Lantern to help build a comprehensive inventory of its value chain greenhouse gas (GHG) emissions (Scope 3).

​

Working closely with Wedge staff in energy management, finance, and with senior leadership support from Wedge’s Technical Services Director, Lantern identified, collated and analysed Scope 3 data across relevant categories including: waste, fuel and energy-related activities, purchased goods and services, business travel and employee commuting.

​

Following the GHG Protocol guidelines, Lantern calculated Scope 3 emissions, with all methodology and boundaries clearly documented. Lantern also developed a set of recommendations for data improvement, along with tailored data collection templates and practical suggestions to streamline processes. These improvements will not only enhance reporting accuracy in the future but also support emissions reduction opportunities across multiple areas of Wedge’s operations and supply chain.

​

"Understanding our value chain emissions is a vital step in our journey to Net Zero. This work with Lantern gives us the insights we need to make informed decisions and continue leading on sustainability in the galvanizing sector."
