The target is tougher than one proposed by the European Commission, which proposes a 15pc reduction by 2025, and a 30pc reduction on 2021 levels by 2030.
Germany, which has a large automotive industry, is concerned that too strict reductions will hit jobs in the country.
The impetus is part of a programme that aims to reduce greenhouse gases by 40pc on 1990 levels by 2030.
