Green Gateway Initiative: the Challenge
� In the UK market, the air conditioning
industry was perceived to be part of
the environmental problem
� New approach was required to
change the mindset of policy makers,
building developers and public
� Green Gateway Initiative was
launched in 2007 locally by Mitsubishi
Electric’s UK Branch to achieve this

An initiative designed to change the mindset and
position HEAT PUMPS as an effective means to
reduce energy costs and CO2 emissions.
Green Gateway Initiative activities include:
� Demonstrating heat pump technology to UK Members of
Parliament, explaining how “ecodan” is a low-carbon alternative
to gas and oil
� Holding “low-carbon” and “ecodan” seminars about heating.
Presentations given by external and company speakers
�Providing audit tools to accurately measure and compare
energy consumption when efficient equipment (such as heat
pumps) are installed

� Acceptance as partner of the EU Commission’sSustainable Energy Europe (SEE) Campaign and
shortlisted in the “Market Transformation” categoryat the 2008 Awards
� “Best Green Corporate Initiatives Project 2008” at
EDIE (Environmental Data Interactive Exchange)
Awards for Environmental Excellence
� “Technology Award” for energy saving potential at
the Energy Institute (EI) Awards 2008
� Environmental Initiative Award of the Year
at the 2009 ACR News Awards
Green Gateway Initiative Results
Heat pumps gaining recognition among industry and
government authorities as way to meet legislative
requirements and reduce heating costs. Official
recognition and awards include:
