Carbon dioxide emissions fell to 673 million tons, the biggest drop since Germany’s reunification, the agency announced on Friday, confirming preliminary figures published by the Berlin-based Agora Energiewende think-tank in January.

Germany aims to cut its greenhouse emissions by 65% by 2030 compared with 1990, a step toward becoming carbon neutral by 2045. It is currently at around 46%.

“Germany is on track - for the first time. If we stay on track, we will achieve our 2030 climate goals,” Climate Action and Economy Minister Robert Habeck said in a statement.

A drop in energy-intensive industries’ output, along with a rise in renewable power production, contributed to the emissions decline, the agency said.

But the transport and building sectors failed to meet their emissions targets last year, risking the 2030 goals if further measures to decarbonize the sectors were not taken, the ministry said.
