That can range from lifestyle choices such as diet, to increased recycling and a reduction in the use of packaging.
Green mortgages could be a good way to give homeowners the practical solution they need to enhance the efficiency of their homes.
A green mortgage is not a new thing, but is a generic term that can mean different things to different people.
Recognising the need for more green finance options, Kensington has launched its eKo mortgage.
These deals offer homeowners that are making energy-efficiency improvements £1,000 cashback when they adequately improve their efficiency rating in the first 12 months.
This will need to be evidenced by providing the property energy performance certificate and then undertaking another EPC after the work to qualify for the cashback payment.
This is an interesting approach that works for those buying an older property rather than new-build.
The eKo mortgages offer a range of two and five-year fixed rates, all without any completion fee and starting from 3.04 per cent for a two-year deal up to 75 per cent loan-to-value.
These are good examples of innovative thinking in the mortgage market.
