The UK has committed to low carbon targets, 80% total reduction by 2050. This will require buildings including hospitals to become "Net Zero" and even positive contributors toward this target. Research has shown that massive reductions are possible and that with the appropriate strategies there can be cost benefits which would help to ease the financial pressures on the NHS. By embracing low carbon energy as a resource and of value to the community, hospitals could start to see an income stream from their waste energy.
