The Rainforest Alliance launched the world’s first sustainable forestry certification program in 1989 to encourage market-driven and environmentally and socially responsible management of forests, tree farms and forest resources. The organization's SmartWood program helped found the Forest Stewardship Council (FSC), a non-profit organization that promotes responsible forest management globally, in 1993. SmartWood is accredited to certify forestry operations that meet the FSC's environmental and social standards. Operations that earn certification can use a seal on wood products so consumers know that the wood they are buying comes from forestlands that are managed in a way that conserves biodiversity and ensures the rights of workers and local people. SmartWood has certified more than 108 million acres (43,800,000 hectares)
of forest worldwide, making it the largest FSC certifier of forestlands in the world. The Rainforest Alliance's SmartWood program was ranked "top of the class" according to "Wood Products Legality Verification Systems: An Assessment," an independent report compiled by Greenpeace, an global environmental organization.
The Rainforest Alliance also works to connect certified communities and businesses to buyers of forest products. They work to build sustainable livelihoods by helping certified communities and businesses to market their products effectively and increase technical ability. By promoting green building and helping companies that purchase forest products to incorporate sustainability into their sourcing policies, they are also working to increase the demand for certified products.
The Rainforest Alliance's forestry program also provides training and technical assistance to small forestry operations on how to reach certification and educates consumers and people in the forest products industry about conservation and certification.

The Rainforest Alliance launched a sustainable tourism program in 2000 and provides small- and medium-sized tourism businesses in Latin America with training and tools to minimize their impacts on the environment and local communities. Since there are almost 70 existing sustainable tourism certification initiatives worldwide, the Rainforest Alliance decided that it would be more productive to support local certification programs (rather than creating its own certification body), help increase their international recognition and establish regional networks of certification programs to share resources and information and create standards for certification criteria. They also provide marketing support, training and technical assistance to certified businesses and businesses in the process of becoming certified. In addition, they work internationally to create partnerships with tour operators (hotels,lodges, travel agents, etc...) to green all elements of the tourism supply chain. In March 2008, the Discovery Channel noted that "the Rainforest Alliance has been a leader in developing a sort of meta-analysis of the various programs operating in the Americas - possibly leading to a world-wide standard for what ecotourism ought to achieve."
The Rainforest Alliance works to help people of all ages understand the role that every person plays in biodiversity conservation. They do this through their education site -- developed in conjunction with education experts -- and their Adopt-a-Rainforest program. They also work with several schools around the country, to help teachers implement the lesson plans.
The Rainforest Alliance developed free, on-line curricula that offers complete lesson plans, stories (in English, Spanish and Portuguese), presentations, posters and articles about societies and flora and faunain Latin America, plus on-the-ground conservation projects for kindergarten through eighth grade.
Through the Rainforest Alliance's Adopt-A-Rainforest program, individuals and school groups can donate money to support the programs described in the lesson plans. These donations can be made on the Rainforest Alliance website and describe exactly where the money goes and offers fundraising ideas.

, criticized Rainforest Alliance in his 2007 book Branded! for having "little tangible impact on the actual conditions under which work is done and workers are paid".
, does not offer producers minimum or guaranteed price, therefore leaving them vulnerable to market price variations: as an example, in the 1980s, a pound of standard-grade coffee sold for around US $1.20. In 2003, a pound sold for about $0.50, which was not enough to cover the costs of production in much of the world. The price of coffee has since rebounded somewhat, with prices for Arabica reaching $1.18/pound by the end of 2007 
In March 2007, Ethical Corporation reported that due to higher coffee market prices, Rainforest Alliance Certified farmers on average receive $1.20 per pound, or 9% less than the Fairtrade minimum price and premium and 20% less than the average price paid to Fairtrade certified producers.
Michigan State University professor Daniel Jaffee has criticized Rainforest Alliance certification, claiming that its standards are "arguably far lower than fair trade's" and saying "they establish minimum housing and sanitary conditions but do not stipulate a minimum price for coffee. Critically, they require plantation owners only to pay laborers the national minimum wage, a notoriously inadequate standard.
The Economist, however, seems to favor the Rainforest Alliance's method and notes that "guaranteeing a minimum price [as Fairtrade does] means there is no incentive to improve quality." They also note that coffee drinkers say "the quality of Fairtrade brews varies widely. The Rainforest Alliance does things differently. It does not guarantee a minimum price or offer a premium but provides training advice. That consumers are often willing to pay more for a product with the [Rainforest Alliance] logo on it is an added bonus, not the result of a formal subsidy scheme; such products must still fend for themselves in the marketplace."
, this use of the seal is the "most damaging dimension" of [Rainforest Alliance's] agricultural certification program and "a serious blow to the integrity of certification": "Yuban coffee, a very popular lower-grade canned coffee available nationwide in the US, proudly advertises on the front of its cans that 30% of the contents are Rainforest Alliance Certified. What are consumers to believe about the other 70% of that coffee? That it is pesticide-laced and irresponsible in its water use? In neither of the other certification systems with which [Rainforest Alliance] is associated, FSC forest certification and the Sustainable Tourism certification, would it allow the use of its logo with such a low bar.
The organization counters that this approach encourages larger purchases of beans from certified farms, having a greater global impact on the environment and livelihoods of farm communities as large roasters blend the beans into mainstream brands. Consumer Reports counters Conroy's implication that the label is misleading, judging it to be "clear and meaningful," and calling the Rainforest Alliance Certified label on agricultural products "highly meaningful."
