Under the Energy Company Obligation (Eco) scheme, Blackpool Council has helped residents access funding for home insulation and more efficient boilers which it has credited for the falling emissions.
The biggest fall was in the domestic use of gas and electricity in homes, followed by large carbon reductions from the business and transport sectors.
The government figures showed the drop in emissions from Blackpool homes was the largest in the country.
Blackpool Council deputy leader Gillian Campbell said: “This is great news which shows Blackpool households along with this council, are leading the way to make this country greener and more energy efficient.
“Our insulation programmes are a real statement of intent that this council is determined to reduce its carbon footprint and bring residents’ fuel bills down too.
“I am delighted with the work that we’ve been doing over the last few years to make residents aware of ways to insulate their homes properly or get better central heating systems.”
The Eco scheme started in 2013 and compelled the UK’s largest energy suppliers to delivering energy efficiency measures in homes but will enter a transitional year in March 2017 before a new scheme is phased in.
