Climate change means long-term changes in temperatures and weather patterns. Human activities, particularly burning fossil fuels, increase greenhouse gases and warm the climate. Reducing emissions and adapting to changing conditions both matter.
Low energy, low carbon and net zero
Low energy concerns energy demand. Low carbon concerns emissions, including the energy source and potentially materials and construction. A net-zero claim needs a defined boundary, measurement period and evidence for how residual emissions are addressed.
