The World Wildlife Fund (WWF) last week attacked regulations surrounding the construction of coal-fired power stations for failing to demand they adopt Carbon Capture and Storage (CCS) technology.
The conservation organisation claims that demands that plants need only be capable of retrofitting CCS will lead to unnecessary delays to widespread introduction of the technology.
"Claims of CCS readiness do little more than refer to the need for power plants to leave space on the site for CCS equipment to be retrofitted in the future," said WWF-UK head of climate change Keith Allott.
"There's no deadline for conversion to full scale CCS, let alone any guarantee that this would be met."
CCS is a term for a range of methods used to capture carbon dioxide and is a way of cutting the CO2 emitted by up to 90%.
The Department for Business, Enterprise and Regulatory Reform is running a competition for a method of post-combustion CCS to be developed in the UK.
