SGN

Why it's on ClimateTicker

SGN is a regulated natural gas distribution monopoly whose core business — piping fossil gas to 5.9 million homes and businesses — is structurally misaligned with a 1.5°C pathway, because methane shrinkage accounts for ~98% of its carbon footprint. The company's genuine climate story is a slow, regulator-driven transition pivot: replacing cast-iron mains to reduce leakage, injecting biomethane, and piloting hydrogen repurposing of its high-pressure network. The transition narrative is real but embryonic, and the ultimate fate of the gas network under UK and Scottish electrification policy remains deeply uncertain — making this primarily a 'managed decline' asset dressed in green language.
