Today, organizing any kind of large-scale event, whether an academic conference or an urban festival, inevitably leaves a mark on the surrounding area. Regardless of size, all events generate a visual impact. Emissions of greenhouse gasesThey consume water and energy, and produce a huge amount of waste that, if not managed properly, ends up weighing down the planet.
The key to changing mindsets is not just trying to be "greener", but quantify the actual damage in order to be able to act upon it. If we don't measure what we do, we're groping in the dark; that's why moving from theory to monitoring is the fundamental step for sustainability to stop being a buzzword and become an operational standard.
Understanding Environmental Aspects and Impacts
To avoid confusion, the first thing is to distinguish between appearance and environmental impact. environmental aspect It is basically everything the event "demands" from the environment (resources, water, electricity) and what it "returns" (fumes, garbage, spills). It is the direct cause of the disturbance.
Furthermore, the environmental impact It is the real consequence of those aspects. We are talking about air pollution, aquifer depletion, or soil degradation. To have a complete view, we must apply a life cycle perspectiveThis means that it is not enough to look at how much electricity is used on the day of the event, but to consider everything from the extraction of raw materials to manufacture the furniture to the final destination of the promotional gifts.
Strategies for a Minimal Footprint in the University Environment
In the university environment, where hundreds of conferences and fairs are held each year, some very interesting models have been implemented. One of the most ambitious goals is the zero waste productionThe goal is to ensure that absolutely nothing ends up in landfills. This is achieved through prevention, eliminating single-use plastics and promoting reusable tableware and modular signage.
Many centers have adopted the mandatory "green seal"A certification system that incentivizes organizers to reduce their waste levels. In some cases, waste generated per event has been reduced by more than 70% in just two years. For this to work, it is vital to appoint a sustainability coordinator or an ambassador to ensure that suppliers are committed to the environment.
Carbon Footprint Management and its Scope
The carbon footprint is the total measure of greenhouse gas emissions, expressed in CO2 equivalent. To calculate it correctly, emissions are usually divided into three categories or scopes. range 1 It focuses on direct fuel consumption, such as heating the premises or the environmental impacts of fossil fuels used in the organization's own vehicles.
El range 2 It measures indirect emissions from electricity consumed in heating, cooling, lighting, and electronic equipment. Finally, the range 3 It is the most complex and where the bulk of the problem usually lies, since it includes the travel of attendees, the origin of the food and the manufacture of the merchandise.
Pillars for Reducing the Impact of Urban Events
If we want an event to be truly respectful, we must address four main fronts:
- Mobility: This is the most critical factor, accounting for up to 80% of the total footprint. Priority should be given to locations near public transport, and the use of bicycles or carpooling should be encouraged.
- Feeding: Catering services should prioritize locally sourced products (zero-kilometer products) and plant-based menus, which have a much smaller water and carbon footprint. Furthermore, it is essential to manage surplus food through food banks.
- Energy: The use of LED lighting and the contracting of 100% renewable electricity are fundamental. Some innovations include the use of kinetic energy, such as bicycles where attendees generate the electricity to charge their mobile phones.
- Waste: Implementing the circular economy through the 8Rs. This involves everything from prohibiting the use of plastic bags and disposable until used reusable bottles and water "bricks" biodegradable, which also serve as an eco-friendly advertising medium.
Measurement, Monitoring and Compensation
Once the improvements are implemented, it's time to measure the results. Specific indicators are used for this purpose, such as kWh of energy, m3 of water, or kilograms of paper and cardboard generated. Data collection can be manual or automated, using surveys for attendees or reports from service providers.
The ultimate goal is to go through three stages: calculate, reduce and compensateThe calculation gives us the starting point, reduction is the direct action on the process, and compensation is the last resort, where environmental projects (such as planting trees) are financed to neutralize emissions that have been impossible to avoid.
The transition to sustainable events is an irreversible path, driven also by regulations such as the Waste and Contaminated Soils Law in Spain, which penalizes non-reusable plastic packaging. Adopting these practices not only helps the planet, but also improves the entity's reputation organizer and can represent considerable long-term economic savings thanks to resource optimization and logistical efficiency.
