About Our Sustainability Efforts

At The Westin San Diego Gaslamp Quarter, we embrace our responsibility for environmental stewardship and are committed to integrating leading environmental practices and sustainability principles into our core business strategy.

-The Big Picture: By 2025, Marriott International has a corporate goal of reducing our overall environmental footprint by 15% in water intensity, 30% in carbon intensity, 45% in waste landfill and 50% in food waste.

-Our Role: We actively work to reduce our environmental impact and to continually improve practices aimed at conserving natural resources, minimizing waste and pollution, and enhancing indoor environmental quality.

-Promote the Green Way: Raising environmental awareness among our associates, guests and within our communities is paramount. The more we learn, the better choices we can make, and the greater impact we can make collectively.

Sleep Well:

A Sustainable Night’s Stay

We invite guests to Make a Green Choice by forgoing full housekeeping services for up to two consecutive days (excluding check-out day). As a thank you for participating, guests can receive Marriott Bonvoy™ points or choose to have a tree planted on their behalf. The benefits don’t stop there, when you opt into Make A Green Choice, you save...

-Enough electricity to run an Energy Star-rated laptop for 10 hours

-787 cups of water; that’s enough for 1 person to drink 2 cups per day for a year

-7 oz of chemicals which reduces toxicity in the environment

-Enough energy to heat a 400 square-foot room at 70 degrees for 4 hours when its 10 degrees outside

In planning our newly refreshed guestrooms and suites, we also kept sustainability in mind and added an energy management system, high-efficiency air filters, low flush pressure toilets, low flow aerators and 100% of lighting is LED.

Go Green for Your Meeting

Small changes to your set-up make a big impact. Start with a linen-less table decorated with a live potted plant, and use water pitchers as alternatives for bottled water. All of our paper products are made of a minimum 30% post-consumer recycled content, and recycling receptacles are strategically placed in the room.

What and how do we recycle? Almost everything!This includes paper, cardboard, aluminum, tin, glass and plastics. Our single-stream recycling program makes it even easier for our guests to participate.

For audio-visual needs, we encourage you to partner with our onsite provider, PSAV, utilizing ENERGY STAR® rated equipment, flip charts made of 30% post-consumer recycled content, and all markers made of certified non-toxic water-based ink.

Eat Well:

Eating Clean, Re-Defined

We support Marriott International’s #skipthestraw campaign as part of our Serve 360 efforts to reduce our environmental impact. If needed, straws are available upon request.

Seafood, and addressing its impacts, is critical for the health of our planet, the communities where we do business, the businesses we operate, and the guests we serve every day. By integrating sustainability and trace-ability, and improving our seafood procurement, we are committed to sourcing, offering and preparing higher quality sustainable products that positively contribute to the environmental, economic, and social well-being of farming and fishing communities.

We proudly offer shade grown, organic coffee and fair trade coffee, tea, cocoa and sugar; and our restaurants and banquet department are Styrofoam-free.

Food waste is minimized with our composting partner, Miramar Greenery, where it returns to Mother Earth. Cooking oil is filtered to extend its life and then recycled once unusable for cooking. We partner with New Leaf Bio fuel who takes our used cooking oil and turns it into high-quality bio-diesel. This is then used in place of petroleum diesel, reducing greenhouse gas emissions by 80%.

Play Well/Move Well:

Follow the Green Road

Guests are encourage to experience the city on foot, by bike or utilizing public transportation including San Diego’s free FRED transportation circuit.

Drive electric? Rest assured, electric vehicle charging stations are available with our valet.

Feel Well:

Every Initiative Matters

At Marriott International, we embrace our global responsibility to be a force for good. There is even more happening behind the scenes that makes a lasting impact to reduce our energy and water usage, including usage of a STEM battery storage system, high efficiency boilers, and low water usage foliage. We care about the dangers of releasing chemicals into the environment and have made a conscious decision to use Green Eco-lab cleaning products throughout hotel.
