EU Technical Measures


EU project on supporting technical measures to reduce emissions from existing heavy duty vehicles

Sadler Consultants  led a research project for the European Commission on how the EU can support the greater use of technical measures, such as after-treatments, fuels, oils and tyres, that can help reduce the emissions of particulates and NOx from existing heavy duty and captive fleets.
This project involved reviewing technical measures, providing data for the EU cost effectiveness model and developing policies to support them. The key policy is developing an EU-wide certification scheme for retrofits to assist LEZs and road tolling schemes, but also include EU guidance, informal/semi-formal city groupings, and changes to the state aid system.
This project is now completed, and the final report submitted to the Commission, and is available below:

We run an EU-wide Network for Low Emission Zone authorities, which includes a public website with the only single source of iinformation on LEZs in Europe - www.urbanaccessregulations.eu.
Sadler Consultants has undertaken many reports and on air quality policy, including on Low Emission Zones, air quality policies in London, Europe and Asia, the impact and reduction possibilities for construction emissions.
Prior to setting up Sadler Consultants, Lucy was head of Air Quality for the Mayor of London, and lled the production and implementation of London’s first Mayoral Air Quality Strategy, one of the first to be implemented in any large city. This included:

*  the London Low Emission Zone Feasibility Study
*  air quality advice to the Central London Congestion Charge
*  assessing & guiding the air quality work of 33 London local authorities
*  negotiating emissions standards for London buses and taxis
*  producing emissions inventories, and guidance and helplines for emissions inventories for DEFRA
*  managing air quality modelling contracts
*  assessing planning applications and unitary development plans
*  ensuring consistency with all the Mayor’s other strategies, in particular transport, landuse planning,
    energy, noise and climate change
*  explaining policies to both public and stakeholders
*  developing measures that are well-founded in science, as well as being implementable, effective and
    politically acceptable
* a good understanding of political and stakeholder realities
*  significant experience of EU and national Government issues


Lucy’s work has also included advice to stakeholders, the UK Government and the EU, as well as cities and Governments in China, Hungary, India and around Europe.


Lucys previous background also included work on Government guidance and helplines, and prototype air quality monitor development and use.

Sadler Consultants (2005 - ) – Director

In August 2005, Lucy set up Sadler Consultants, as an independent consultancy specialising in air quality policy, and other aspects of air quality. A list of example publications completed as Sadler Consultants can be found under Recent Work.

The projects undertaken include the Low Emission and Environment Zones in Europe Network providing support to Low Emission Zone (LEZ) authorities and the only single source of information on LEZs around Europe, leading an EU research project: “Assessment of the impact on costs and emissions of technical measures on existing heavy duty vehicles and captive fleets”; reviewing technical measures including retrofits and cleaner fuels, providing data for the EU cost effectiveness model and developing policies to support them. Air quality management training under the German GTZ (foreign aid agency) for Indian delegates, leading international conferences including PRONET and Dustconf, various reports and talks on topics such as air quality management, low emission zones, emissions abatement possibilities.


Greater London Authority (2000 – 2005) – Principal Policy Advisor and Lead Officer on the London Air Quality Strategy for the Mayor of London

As the lead officer responsible for producing London’s first Mayoral Air Quality Strategy Lucy was responsible for devising, negotiating, and most importantly implementing policies and proposals to improve London’s air quality. Meeting the national objectives and EU Limit Values is a huge challenge for London.


Much of the work involved negotiating, liasing and networking to agree and implement the Strategy both with other interests inside the Authority, and with external stakeholders including local authorities, industry and transport operators. Lucy is well versed in political awareness having worked with amongst others, the Mayor, the 25 elected Assembly members and external stakeholders.


The most interesting of the many projects Lucy was involved with are:


*   Producing the Mayor’s Air Quality Strategy
*   London Low Emission Zone Feasibility Study – technical lead on the Steering Group for phase 2, and       author of phase 1
*   Air quality advice to the Central London Congestion Charge, and assisted in negotiating the 100%         discount on the cleanest alternatively fuelled vehicles


Assessing the air quality work of the 33 London local authorities, both of air quality assessments and action plans. Co-ordination of, guidance for and the sharing of information and best practice for London borough air quality work was essential to maximise the improvement of air quality in London.


Lucy had responsibility for ensuring that the air quality aspects of the largest planning applications were adequately addressed, and giving recommendations to refuse planning permission where appropriate. Ensuring that London planning guidance adequately included air quality was also an important part of this.

Close co-operation was essential on transport, energy, noise, planning, culture, biodiversity, economy, and waste issues, and Lucy ensured that consistency was maintained with these strategies, requiring an understanding of these areas. Consistency was also essential with sustainable development, the UK and London’s commitment to climate change, and particularly CO2 reduction targets

Lucy had responsibility for ensuring that the air quality aspects of the largest planning applications were adequately addressed, and giving recommendations to refuse planning permission where appropriate. Ensuring that London planning guidance adequately included air quality was also an important part of this.

Lucy had significant experience of EU and national government issues, as well as those in a number of other countries, particularly in the EU. Keeping informed of systems in other EU member states, through various conferences and dialogues was also required.
