New Impax fund raisings point to strong demand for environmental investing

September 20th 2007

Impax Group plc ('Impax'), the AIM listed investment management company, has
today announced two successful fund raisings, taking the funds managed or
advised by its wholly owned subsidiary, Impax Asset Management Ltd ('IAM'), to
over £930 million.

Impax Environmental Markets plc

This morning, Impax Environmental Markets plc ('IEM'), an environmental
investment trust listed on the London Stock Exchange ('LSE') that is managed by
IAM, held an Extraordinary General Meeting at which a vote was passed to issue
£105 million of subscriptions for C Shares.  It is expected that these shares
will begin trading on September 21st 2007.  The addition of the C Shares will
take the aggregate net assets of IEM to over £370 million, reinforcing the
trust's position as the leading closed end fund investing in the environmental
sector.

IEM invests predominantly in small and mid cap growth stocks active in
environmental markets throughout the world.  Over the past 4 years, IEM has
outperformed the FTSE All Share Index by 35 percentage points.

New Large/Mid Cap Fund

Impax has also announced today that it has been appointed as investment adviser
to the DIAM World Environmental Business Fund (the 'DIAM Fund'), a new fund that
will invest in a portfolio of mid-cap and large-cap stocks active in
environmental markets.  The DIAM Fund, which is incorporated in Japan, is an
open-ended public fund managed by DLIBJ Asset Management and DLIBJ Asset
Management International and has raised Yen 6.2 billion (£27 million).

Ian Simm, Chief Executive of Impax Group plc, commented: 'The further expansion
of our investment trust and the launch of the new fund in Japan reflect the
strong demand from investors for exposure to environmental markets.  Over the
past twelve months, Impax has doubled its funds under management, making it one
of Europe's largest and most experienced investors in this high growth sector of
the economy.'
