Greater London Authority (GLA) Emissions

Currently, the GLA is continuing with their emission policy as detailed in the table below; however, all generators, those between 37 - 560 kW, are now required - as of 1st January 2024 - to be Stage V, but Stage IIIA will only be permitted on site where Stage V is not feasible. [Note: there are no Stage IV generators, which is why the threshold moved to Stage V.]

Exemption applications are reviewed on a case-by-case basis, and sites must include the following evidence in their application:

- Correspondence with the supplier demonstrating that the site has asked for Stage V, but the supplier currently doesn't have a suitable Stage V available.

- Details of the supplier's Stage V current fleet and order to demonstrate that the supplier is quickly moving towards a Stage V fleet.

- If the supplier has Stage V in their fleet, but these are not suitable for the power demand on site, the site/supplier must also provide loading data to demonstrate the Stage V loading issues, and that bolt-on Battery and/or Fly-wheel technologies will not resolve those loading issues. 

Exemptions can only be applied for on the Mayor of London's NRMM Register

This will also apply to generators powering Tower Cranes from 1st January 2024.

 

As from January 1st 2025, the Greater London Authority (GLA) now stipulates higher controls on exhaust emissions from construction plant. All NRMM (Non-Road Mobile Machinery) will be required to meet Stage IV as a minimum.

If companies have any specific queries about the machinery on site, then they can contact NRMM@london.gov.uk

The following table shows the current and proposed requirements.

Further information on NRMM emissions and Opportunity Areas can be found on the Mayor of London, London Assembly website - GLA's NRMM information

Other local authorities are considering introducing controls on emission from construction machinery, and they will be strongly influenced by the GLA policy. This means that areas outside London may also be affected by these changes.

 

Frequently Asked Questions

Q) We do not hire cranes, we specialise in MEWPs (Mobile Elevating Work Platforms).  Do these come within scope of the proposals?

A) MEWPs do come within the general requirements from 2015, and the step change in 2020. CPA will be talking with IPAF and other industry bodies to help prepare the sector. The particular change that GLA are considering in 2018 applies only to the (current) exemption for mobile cranes, and has no impact on MEWPs.

Q) What about Crawler Cranes that do not travel on the road. Is anyone making it clear that there is a difference?

A) There was a block exemption for crawler cranes when the controls were first introduced in 2015. However, this was removed in 2016 because GLA had evidence that sufficient crawler cranes were available to meet demand, and there was no continuing justification for the block exemption. It is possible for a site to request exemptions for machines, but this has to be done on a case-by-case basis. 

Q) Are GLA looking for a total ban or will there be a daily charge?

A) The GLA do not have the statutory powers to levy any charges for this, as the rules are made under planning legislation. The principle is that it is a total ban, although sites can apply for exemption for particular machines on a case-by-case basis.
