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

Green Gateway Initiative

10 Point Plan


8

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

The Green Gateway Approach


9

� 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:


10

� Gain pan-European acceptance of heat pumps and other

energy saving products

� Effectively position Mitsubishi Electric as a leading sustainable

company in Europe in a unified manner

Green Gateway: Going Forward

A success in the UK, actively considering extension of

Green Gateway Initiative to other EU markets
