A product or system is only as low carbon as the materials and components from which it is made. More and more, companies expect their suppliers to have strong corporate and social responsibility policies that meet their own high standards. A sustainable supply chain will ultimately increase profitability. - Description added by: David Lockie

A product or system is only as low carbon as the materials and components provided they do not increase during its life the overall environmental burden  with its maintenance and repair costs. - Description added by: Andrew Schofield

Renewable and alternative energy sources are set to play an increasingly important role in providing the electricity, heat, cooling and fuels that society needs. There is a wide range of energy sources such as solar (both photovoltaic and solar thermal), wind, bio-fuels and biomass, hydro-electric, geothermal and heat pumps. - Description added by: David Lockie

Heating and cooling are typically extremely energy intensive technologies. In the United Kingdom the majority of heating in our homes and buildings is provided by burning natural gas. Renewable energy technologies such as solar heating, or heat pumps provide a sustainable low carbon alternative. Condensing boilers, and combined heat and power (CHP) also offer significant energy savings. In this circumstance energy that would have otherwise been wasted (which happens in traditional power plants) is instead used by the local community via a district heating scheme. Alternatively, a micro CHP system (such as a residential fuel cell, or Stirling engine) produces both electricity and heat to serve a local heat demand i.e. for a particular building. Energy efficiency technologies such as low carbon ventilation solutions can reduce the energy demands of buildings. - Description added by: David Lockie

Appliances, whether domestic, commercial or industrial, are consumers of electricity. A low carbon economy requires that these appliances be very energy efficient, both in use and when on standby. However, there are embedded carbon costs in appliances, from their manufacture and transport. These also needs to be considered when choosing an appliance. - Description added by: David Lockie

Communities consist of homes, businesses and sometimes industrial concerns, with infrastructure like health care, transport, communications, government and utilities. Many decisions about low carbon need to be considered at the community level in order to ensure that ‘joined-up thinking’ is applied to the process.
