Grant welcomes landmark Renewable Heating Obligation (RHO) Report published by TAZCH
The new reports details how the Irish Government could slash residential heating emissions quickly, cheaply, without disruption to consumers and at zero cost to the taxpayer. This can be done by altering its proposed Renewable Heat Obligation (RHO) rates of 1.5% and 3% and introducing a 20% blend of renewable liquid fuels.
