Net zero by 2045: what Scotland's climate law means for construction
Scotland has one of the earliest legal net zero dates in the world. The Climate Change (Emissions Reduction Targets) (Scotland) Act 2019, which received Royal Assent on 31 October 2019, sets 2045 as the year by which net emissions must reach zero, five years ahead of the UK-wide target.
Why construction is central
Buildings matter twice: once for the carbon in materials and construction, and again for the energy used to heat and run them for decades. Construction and demolition also generate a large share of the UK's waste, which is why projects like the K-Briq recycled brick drew attention.
What the target pushes towards
- Zero-emissions heating in new homes, as tested in the Edinburgh Home Demonstrator at Granton.
- Modern methods of construction, which move work into factories to cut waste and improve quality; a Scottish evidence study looked at what offsite methods could do for affordable housing.
- Skills in low-carbon techniques such as Passivhaus (training example).
The legal target is fixed; the route is not. Ministers can adjust the target year only under conditions set in the Act, and interim milestones have been revised since 2019, so check the current text on legislation.gov.uk.
