1.Patagonia’s "Don’t Buy This Jacket" campaign
Patagonia stands out as a timeless case of genuine, environmentally friendly marketing. In a very bold 2011 New York Times ad released on Black Friday, the outdoor clothing company directly told consumers, "Don't Buy This Jacket." The campaign talked about the environmental cost of consumption and invited the customers to think twice about buying, and instead, they could fix, share, or resell their gear. Such a radical honesty was absolutely in line with the brand's core values of durability and being eco-friendly.

Outcome:
The brand displayed radical transparency; hence, a very big brand trust was created.
The communication was backed up by the company’s long-term activities, for example, its Worn Wear program for repairs.
Patagonia was able to paradoxically increase its sales and loyalty.
It helped Patagonia to be not only a real leader and trendsetter but also recognized as such by others.
2. IKEA’s circular business model
IKEA’s eco-friendly marketing strategy is exemplified by real measures such as its "Buy Back & Resell" program, in which customers can deliver old IKEA furniture and get store credit. The firm also commits to eco-friendly sourcing and makes use of such materials as bamboo and recycled wood for its goods.

Outcome:
Thus, the company turns sustainability into a democratic concept, which is affordable and a wise choice for the mass market.
The company protects itself from facing resource shortages in the future and, at the same time, builds strong customer loyalty.
IKEA’s move is not only about marketing campaigns, but it also shows the company’s long-term vision far beyond that.
3. Unilever’s "Sustainable Living Brands"
Unilever made sustainability the center of its corporate strategy with the help of the "Sustainable Living Brands" program. This program identifies brands like Dove, Ben & Jerry's, and Hellmann's that have a strong social or environmental purpose and are thus groupers. Unilever announced that these purpose-driven brands have increased their revenue 69% faster than the rest of the portfolio.

Outcome:
The company connects purpose directly with brand identity and product innovation.
The project demonstrates that sustainability can be a major driver for business growth, rather than just a cost center.

Outcome:
One of the main reasons for the success of the campaign is that the activism reflects the long-term values of the founders that have been there for years, and, thus, there is no greenwashing.
It transforms customers into fervent brand advocates and enthusiasts.
The brand is not scared to lose some consumers by this move, thus making its relationship with the core, like-minded consumers stronger.
Executing its platform for advocacy, it allows customers to be a part of the solution by simply making a purchase.

6. TOMS Shoes' evolving mission
TOMS was the brand that was built around the concept of "One for One", where the company would donate a pair of shoes to a child in need for every pair purchased. TOMS has moved on from the "One for One" model, but it is still committed to sustainability through its responsible packaging practices.
TOMS takes great care of its packaging by using 100% recycled, recyclable, or sustainably sourced materials for its shoeboxes and is a member of the CanopyPack4Good initiative that supports forest conservation.

Lush uses recycled materials for the products that come in packaging and gives back to customers through a pot recycling program that rewards them.

Outcome:
The company doesn't shy away from the problem of plastic waste but instead throws light on it with a solution that is both visible and impactful.

9. Starbucks' waste reduction programs
Starbucks is avoiding the environmental consequences of disposable cups by working on several fronts. The business launched reusable cup programs, strawless lids, and set a target to halve waste by 2030. In some places, their "Borrow a Cup" initiative enables customers to take a reusable cup and return it at a later time, thus marrying convenience with sustainability.

Outcome:
By modifying the behaviour of customers on a massive scale, the brand is contributing to the solution of the problem.
The initiatives are convenient for customers, thus the probability of them taking part is high.

Apple’s green marketing is heavily reliant on the changes the company is making in the use of recycled materials across its product lines. By 2025, the firm is committed to using only 100% recycled cobalt for batteries designed by Apple and 100% recycled rare earth elements for all magnets. The push for material innovation is a large part of the company's environmental messaging.

Outcome:
One of the ways to tell the sustainability story is to align it with Apple's reputation for being a pioneer.
The points made in the statement are clear, ambitious, and supported by a definite timeline; hence, they are more trustworthy.
It is a step in the right direction towards the problem of resource extraction for electronics.
Making sure the brand stays in line with the increasing worldwide rules on electronic waste and the supply chain is another plus for the brand.
11.Tesla’s core mission
Tesla may be selling electric vehicles, but the most sustainable marketing tool that sustains the brand over time is the core mission itself: "to accelerate the world's transition to sustainable energy". Every single thing from its cars to solar roofs is marketed as the "larger, purpose-driven" vision, helping the planet.

Outcome:
This is the most honest kind of branding as the company’s whole identity is based on one thing - sustainability.
The company secured the brand’s future by foreseeing the changes in regulations and consumer preferences that would favor clean energy.
By doing so, it amassed a devoted community of users who consider the mission as important as the product.
The firm differentiated Tesla from non-environmentally friendly car manufacturers, who were slow to react to the trend.
12. Interface inc.’s climate take back
Interface, a modular carpet manufacturer, represents a perfect B2B sustainable marketing example. First of all, the company achieved its "Mission Zero" objective, which means that it had no negative impact on the environment by 2020. Subsequently, it introduced "Climate Take Back" to become a carbon-negative enterprise. "Net-Works," a process whereby old fishing nets are used for making carpets, is one of the many programs that embody the brand's pledge.

The Hershey Company has charged ethical sourcing with being at the heart of its sustainable marketing. Since 2020, the company has been sourcing 100% of its cocoa from independently verified sources, and is partnering with organizations such as Fair Trade USA and Rainforest Alliance to that end. The outcome of that is that farmers get support for good agricultural practice, and the environment is protected along the supply chain.

Outcome:
It does an excellent job of addressing customers' most burning concerns about child labor and deforestation.
Third-party certifications serve as a different level of verification and trust.
In addition, it would be a great help in ensuring the long-term continuity of their primary raw material supply.
It speaks about the product’s origin in a positive way, thus giving more emotional value to the brand.
14. Timberland’s tree planting program

Apart from the product, its Tree Planting Program is a pledge to plant a tree per product sold, and it has planted over 10 million trees so far.

Outcome:

The tree-planting program, thus, furnishes the consumer with a positive emotional bond and sense of participation.
It develops a comprehensive brand image that revolves around the concept of sustainability and environmental stewardship.
It offers a very straightforward and quantifiable metric (trees planted) that consumers can help influence.
