A NetZero University Hospital

University Mollet Hospital has successfully achieved Net Zero in direct emissions

An internationally distinguished green hospital: 85% less CO2 emissions in 11 years.

Our Mollet University Hospital has won the

Silver award in the Ashikaga-Nikken Excellence Award

for Green Hospitals category of the International Awards 2021.

We are part of the problem: we must be part of the solution

Hospitals are some of the public centres with the greatest energy impact on the environment. For this reason, green culture must be part of the strategy and permeate the structure and processes of our centres. We work on waste management, appropriate use of resources, mobility, clinical management, and optimization of processes in order to reduce the environmental impact of our activity. Because, just as we are part of the problem, we must also be part of the solution.

Natural courtyards and sustainable architecture

Natural courtyards filter natural light in all rooms, reducing light consumption by 40% and CO2 emissions by 280,000 kg.

Radiant ceilings and sustainable roofs

The gravel and plant rooftops improve the thermal insulation and acoustic comfort. The radiant ceilings are an air conditioning system.

Collection and use of rainwater

An 80m3 cistern collects rainwater for the courtyards. In 10 years, annual water consumption had been reduced from 32,000 to 26,000 m3.

Recycling and waste management

In 10 years we have increased from 9 to 25 the types of waste we manage. We will continue to focus on recycling and waste management.

Sustainable processes

Reduction of length of stay in inpatient units

1 day of hospitalization generates 7kg of waste. If unnecessary stays are reduced, the environmental impact is also reduced. We prioritize home hospitalization and implement processes such as the Fast Track for knee and hip replacement to reduce hospital stays.

Avoid unnecessary travel & mobility

7% of indirect emissions are due to transportation. For this reason, we improve processes to reduce trips to the hospital. Online consultations have increased by 24%, we have implemented a new high-performance urology outpatient visit and a new channel of the Rehabilitation Service to improve follow-up of treatment from home

Avoid unnecessary duplication of diagnostic tests

High impact of diagnostic tests on energy consumption and waste generation. We analyze the processes to avoid unnecessary diagnostic tests for the benefit of patients and the environment

New more efficient systems

We work on permanent projects such as the recovery and treatment of anesthetic gases that seriously injure the ozone layer, improvements to the sterilization circuits to save water, the use of recyclable materials for the clothing of the surgical block, the treatment of the waters of the dialysis plant.

Governance, culture and education

The primary objective of the FSM was to prioritize the well-being of people and the environment.This strong focus on social and environmental responsibility has guided our goals and achievements throughout the years, resulting in our certification and recognition as a healthy and sustainable company.

From governance to all professionals

It all began with the commitment of senior management and institutional governance to define our strategy for climate change mitigation and the fulfillment of the 2030 agenda. This commitment was clearly expressed in policies, principles, and strategic objectives. Engaging various stakeholders, particularly our professionals, is crucial to achieving our objective. We have made environmental training mandatory for our staff and conducted a survey to gauge their perception, knowledge, ideas and training on climate change.

The result

The University Mollet Hospital has achieved a Net Zero in direct emissions.

We have reduced direct CO2 emissions by 85% in 11 years and the remaining 15% of emissions has been compensated through voluntary participation in the OCCC's compensation program

Our Goal

To achieve a carbon neutral footprint by 2050

Our spaces, environment and processes contribute to improving health. The Mollet University Hospital stands out for its architecture, a paradigm of this comprehensive approach and of our commitment to climate change
