'Carbon Positive' ‘carbon zero’, ‘carbon neutral’, ‘zero energy’ or ‘zero emission’

• The terms ‘carbon zero’, ‘carbon neutral’, ‘zero energy’ or ‘zero emission’ apply to buildings that use renewable energy sources on site to generate energy for their operation, so that over a year the net amount of energy generated on site equals the net amount of energy required by the building.
• Carbon positive moves beyond carbon zero by making additional ‘positive’ or ‘net export’ contributions by producing more energy on site than the building requires and feeding it back to the grid.
• Carbon positive projects can make significant contributions by helping to address the carbon intensity and damaging impacts of past building practices and lifestyles, and by offsetting situations where carbon zero homes are not possible.
• Also in such areas carbon sequestration is more than carbon emissions and not just zero emissions.
