ABU DHABI – More countries may be considering nuclear power to help them meet their energy security needs while tackling climate change, but the time taken to ramp up nuclear power supply will exceed the 2030 timeline for the world to nearly halve its emissions.

Mr Francesco La Camera, director-general of the International Renewable Energy Agency (Irena), told The Straits Times this in an interview on Jan 16, saying that countries should instead focus on ramping up renewable energy supply.

Climate scientists have said greenhouse gas emissions have to be cut by 43 per cent by 2030 to limit global warming to 1.5 deg C above pre-industrial levels.
