The Committee on Climate Change (CCC) has published its advice on how Wales can meet its legally binding carbon emissions reduction target of at least 80% by 2050.
The statutory body recommends Wales sets a first carbon budget for the period 2016-20 which limits emissions to an average of 23% below 1990 levels, and a second carbon budget (2021-25) to an average of 33% below 1990 levels.
The CCC also recommended an overall emissions reduction target of 27% by 2020, 45% by 2030 and 67% by 1990.
The body said the Welsh government's recently announced target for 70% of power consumption to be generated from renewables in Wales by 2030 is consistent with its scenarios.
“The Welsh government, together with many Welsh energy and environmental organisations, has called on the UK government to do more to support onshore wind and solar development in Wales,” it said.
“It is important that a way is found to deploy these technologies where they meet local planning criteria; the Welsh government can help to encourage low-carbon electricity through use of public procurement and use of planning powers.”
