The UK and Japan have reaffirmed their plans to promote mutual cooperation both in the public and private sectors, and recognise the importance of reducing carbon emissions.
Energy secretary Ed Davey met Shinzo Abe during a two-day visit by the Japanese premier.
The partnership hopes to continue to maximise the opportunities for UK-Japan commercial partnerships in low carbon goods and services, a sector now worth $5 trillion globally and growing at almost 4% a year.
UK and Japan will continue to work closely on international climate change and energy security issues including through the UK-Japan Energy Dialogue.
The two countries will also increase the scope for further co-operation and information sharing on policies (including information exchange with the private sector, as needed) on energy efficiency, nuclear energy, renewable energy, smart communities, energy storage, CCS technologies, electricity market reform, competitive and flexible gas markets.
In addition, their diplomatic missions will support companies to exhibit their new low carbon energy technology.
During the visit of Prime Minister Cameron to Japan in April 2012, ETI and Hitachi agreed to collaborate on the smart community project entitled Smart Systems and Heat Project.
Currently the two companies are working together on the initial phase of the project which includes system planning and design. In late 2016, the project will enter phase two, the on-site application phase.
The UK welcomes the establishment of the Innovation for Cool Earth Forum by the Japanese government, the first meeting of which will be hosted in Tokyo in October 2014.
ICEF aims to facilitate international co-operation on how innovation can address climate change through global discussions between researchers, business and policy makers.
