Sustainable Events
For over 25 years, we've been bringing people together through exceptional events. As an award-winning, women-owned event management company, we understand that our responsibility extends beyond creating memorable experiences - it's about ensuring those experiences contribute to a better future.
Sustainability isn't an add-on to what we do; it's woven into how we work. From the technology brands we support to the not-for-profit associations we partner with, we're committed to reducing environmental impact while delivering events that captivate audiences and amplify influence. Our approach combines meticulous attention to detail with conscious choices that benefit people, planet, and business alike.
Our Story
Outsourced Events was created by Denise Sharpe and Alexandra Sibley in 2001, then operating out of a small office in Chiswick, West London. By 2007 the company had firmly established itself as a major player in the technology and associations events sectors with some of the world's most well-known technology and association brands amongst its clients.
The Goal
Having both worked in the event industry since the 1990s, Denise and Alexandra's goal was to create an event agency that could integrate so seamlessly with the client's own business needs and processes that they became an extension of their own team. This philosophy set the company apart from the competition back in those early days and continues to do so today.
Our Vision
Bringing people together to create a better world in which individuals, organisations, communities and our planet thrive. Our vision goes beyond events – to nurturing our team, supporting our global customers and community, championing change, spreading happiness and leaving a legacy for future generations.
Our Values
These values serve as our guiding principles, shaping every decision and action we take.
We put people first
At the heart of everything we do lies a fundamental belief: that having happy, fulfilled people is how to deliver exceptional results. That’s why we’ve created an inclusive company where every individual – whether a client, supplier, or team member - is treated with kindness and respect, and has the chance to flourish and grow.
We're partners.
Working collaboratively with clients and suppliers who share our values and priorities, we have forged meaningful long-term relationships, many lasting more than twenty years. Our connections across commercial and not-for-profit sectors means we can cross-cultivate ideas and bring the best of both worlds to our clients’ events.
We care.
Because we care, we work hard to deliver excellence with integrity, compassion, and commitment. We care for our clients, for the wider community we're a part of, and for the planet that sustains us all. We own what we do, every step of the way.
We challenge.
Embracing change and shattering complacency, our proactive approach and passion for innovation means that we always meet our clients’ evolving needs.
We're curious.
We love a challenge and excel at devising creative, progressive solutions to meet them. We expand possibilities, spark bold ideas, defy expectations, and work together to create extraordinary events.
Our commitments/affiliations
Outsourced Events has committed to set near-term company-wide emission reductions in line with climate science through the Science Based Targets initiative (SBTi). The SBTi is a corporate climate action organisation that enables companies worldwide to play their part in combating the climate crisis by setting targets aligned with limiting global warming to 1.5°C.
As a proud member of isla - the events industry's response to the climate crisis - we're part of a collaborative movement transforming how our sector approaches sustainability. Through isla's TRACE platform, we measure and report carbon emissions from our events with audit-ready data aligned with the GHG Protocol, giving us clear insights into where we can make the biggest impact. In 2025, we monitored one of our largeste events carbon footprint, to identify where we can make the biggest impact and inform our sustainability strategy moving forwards.
Building Expertise, delivering Impact
Members of the Outsourced Events team are currently undertaking MBAs that include dedicated sustainability segments, deepening their knowledge of environmental strategy and carbon management.
As well as being members of isla, we are guided and led by the OE Sustainability Task Force. We have committed to training the entire events team so that the team can provide clients with evidence-based advice on minimising their events' carbon footprints through proven sustainable practices.
