Co-operative Financial Services (CFS) has advised people wanting to invest in an ethical or environmentally friendly ISA to come to them.
More than two people in three (67 per cent) consider investing in ISAs offering positive environmental benefit, CFS reports.
"With a green ISA investors can get attractive returns without paying tax on what they earn, and help to support a more sustainable future for the environment," said Zach Hocking, head of savings and investments at CFS.
"I'd urge anyone who is yet to use their allowance for this tax year to think about investing as soon as possible. Miss the [April 5th] deadline and the tax break is lost forever."
Co-operative Financial Services offers ISAs deigned to benefit society and the environment.
These include the a Maxi ISA with Co-operative Insurance which wraps investments in CFS's socially responsible investment unit trusts.
Customers taking out a cash mini ISA are also assured their money will not be used to support businesses which cause harm to the environment.
