About Us:

Regeneration, Economy and Planning in Westminster City Council is a world of extraordinary stories. Where innovative and open-minded people bring everything to the cause. Regeneration isn’t just about bricks and concrete. It’s about communities. It’s about the environment. It’s about the lives of people and how they feel about where they call home.

The Role:

As Principal Whole Life Carbon Officer you can make your own powerful contribution to Westminster’s success. You’ll join the Town Planning team and support our commitment to achieving Net Zero by reducing Scope 3 emissions associated with construction projects. With the support of the Innovate UK fund and in collaboration with Preoptima, we’re currently rolling out our Planning Application Carbon Evaluation and Reduction (PACER) digital platform - this will transform the review of whole life carbon assessments in planning, creating a robust, standardised and transparent process which will upskill officers and collate valuable data for informing policy.

It’ll be your responsibility to oversee the use and integration of this platform, ensuring consistency and accuracy of the review process, liaising with applicants and consultants to ensure its efficient use, and gathering feedback from our stakeholders with the aim of identifying challenges and improving the end-user experience. Supporting Policy Officers as they implement policy and guidance to achieve our Net Zero and Circular Economy aims will be another vital task, and we’ll also expect you to provide advice on whole life carbon requirements, and draft guidance and updates to environmental supplementary planning documents.

But your work won’t stop here - you’ll also assist the Principle Sustainability Officer in reviewing major applications and applications involving substantial demolition, support the review of carbon options appraisals submitted in pre-redevelopment audits, and critically analyse Whole Life Carbon Assessments submitted for planning applications. In addition, you’ll have a number of important budget responsibilities - these include applying and allocating funds to different functions and projects.

About You:

To be a success in this vital role you’ll have well developed technical knowledge of whole life carbon assessments, datasets and carbon conversion factors, and plenty of experience relating to the development and use of digital tools to undertake this sort of work. And as a collaborative, partnership-focused worker, you’ll have promoted awareness of climate change, net zero or environmental sustainability, and supported the uptake of net zero goals. Some knowledge of planning processes would be desirable, as would experience of retrofitting existing buildings, carbon options appraisals, stakeholder engagement and undertaking research to record the impact of interventions.

Capable of learning from experience, sharing your expertise with colleagues and upskilling the council, your superb communication abilities will see you interacting with a diverse range of stakeholders and presenting complex information clearly. This will include writing project plans, progress reports and policy recommendations, interpreting information from different sources and drawing sound conclusions. A critical and analytical thinker with good problem solving skills, you should also be able to plan your time effectively and deliver to tight deadlines.

When it comes to qualifications we’ll look for a degree in a relevant field - for example in architecture, structural engineering, building services or environmental engineering, and a post-graduate qualification or chartership in a related area would be desirable. Highly motivated, your strong commitment to environmental sustainability and the net zero transition will mean you stay up to date with the latest research and best practices in the fields of whole life carbon, the circular economy and sustainability. In addition, you should also have good knowledge of the latest innovations being employed or developed in the construction industry to reduce carbon emissions.
