There are 26 million homes in the United Kingdom. Together they contribute 27% of the UK's carbon emissions, making the housing sector a vital part of the goverment's committment to an 80% reduction in carbon emissions by 2050.

Since 2007, the award-winning SuperHomes network has promoted the benefits of eco refurbishment using free Open Days. Pioneering owners of some of the UK’s most energy efficient homes host free tours and Q&A’s each September. SuperHomes are older homes that have been refurbished for greater comfort, lower bills and at least 60% fewer carbon emissions.

Currently there are over 180 registered SuperHomes in the UK and over 70,000 people have visited one. The aim is to inspire visitors to take action to green their own homes, by providing actionable ideas, such as improving insulation, installing alternative heating sources or producing their own renewable energy. The network hopes to register 500 SuperHomes by 2020 and attract 2 million visitors.

It is estimated that as many as 80% of all UK homes that will be in standing in 2050 have already been built. Of particular concern are the 7 million solid wall properties, most of which are difficult to heat. To meet its target of an 80% reduction in carbon emissions by 2050, the UK should be refurbishing 600,000 homes a year. At the current rate of change it will take over 500 years to refurbish these homes.

Jurgen Huber, who recently joined the network says:

"My house is now 100% carbon neutral. Along with my wife and two children, we use and generate 3300 kWh of electricity. We have no gas connection so we cook with the most energy efficient induction cooker, we heat water with an electric instantaneous water heater, and we heat rooms with a highly air source heat pump and electric underfloor heating. This is only possible because we insulated the house to a very high standard."

Huber explains that the first phase of his home renovation was done on a budget of £4000. This paid for all insulation materials, the air source heat pump, an induction cooker, and LED lighting. The PV solar panels added afterwards cost £12,000 and were financed with a bank loan. In 8 years Huber may make a bit of money but that’s secondary. He wanted to prove that anyone can have a retrofitted energy neutral house on a tight budget.

"The result is that we’ve a very comfortable home that can be quickly heated or cooled at very little cost. At the same time we’ve maintained the 1920s period character of the property which is something we love."

Huber's testimonial is a good example of how the SuperHomes network harnesses the enthusiasm of pioneering households to demonstrate the benefits of switching to low energy living.

The network's open days help visitors gain the confidence to green their own homes. Free tours and Q&A sessions allow visitors to find out more about both the benefits and the challenges involved in refurbishing an older home.

The IPCC’s Fifth Assessment Report firmly centered on the reality of human-driven climate change. If we don’t take immediate and tangible steps to reduce the consequences of these actions, we will face an environmental crisis that will have a major impact on mankind’s existence. Here in Tokyo, we are extremely concerned about this danger, as it poses a huge threat to our goal of becoming a sustainable and environmentally-friendly city.

In the year 2030, it is estimated that the number of people living in urban areas will exceed 60 percent of the world’s population, and measures at the city level are now crucial. The effects of climate change are already becoming apparent in a range of forms, and Tokyo is no exception. Tokyo has undertaken several measures to mitigate these effects, including launching the world’s first urban cap-and-trade program. In addition, Tokyo is implementing a number of pioneering initiatives, such as measures to counteract storm surges and floods, as well as major earthquakes, and advancing urban planning to realize a more resilient city.

At the same time, Tokyo is working with cities all over the world and engaging in a variety of international activities. In this way, Tokyo’s achievements have been introduced to the world, and we are proud to have gained high recognition in reports issued by the World Bank. Of these initiatives, Tokyo’s cap-and-trade program has received especially high praise internationally. In the program’s first year, FY2010, a 13 percent reduction in total CO2 emissions from base-year figures was achieved.

Further reductions were achieved in FY2011 and FY2012, with a 22 percent reduction from base-year figures recorded for both periods. Achievements to date have far surpassed the mandatory 6 or 8 percent reduction rate, producing a significant effect. Tokyo Cap-and-Trade has introduced retrofitting projects backed by vast amounts of investment for energy-saving technologies. Practical examples of which include the installation of LED lights, more efficient heating equipment, and improved day-to-day operational efforts.

We believe Tokyo’s success is highly reliant on a positive response from various stakeholders, including building owners, developers, tenants and related businesses following our initiatives. A lot of credit needs to go to the facilities under Tokyo Cap-and-Trade, including facility owners and related businesses that responded very positively to the program, resulting in its continued success.

As the 2020 Tokyo Olympic and Paralympic Games approach, Tokyo will continue to promote effective energy conservation and CO2 reduction measures in order to resolve climate change related issues and further strengthen energy policies, including greatly expanding the use of renewable energy, with a view to the global environment.

The World Bank’s “Putting a Price on Carbon” statement is very meaningful, as it will become a driving force behind the promotion of effective measures for climate change mitigation. If all of the world’s cities and nations cooperate to implement a variety of well-thought-out programs, promotion of measures for climate change issues will lead to a reduction in CO2 emissions, and even help avoid an eventual global environmental crisis.

As the Governor of Tokyo, a major city advancing innovative climate change mitigation measures, I endorse the World Bank’s “Putting a Price on Carbon” statement and express my full support. Firmly believing that this World Bank initiative will contribute to the sustainable development of the earth’s environment, Tokyo will call for other cities, nations, and companies that share in the same objectives to come together by endorsing this statement.
