Certified Green

LODI RULES for Sustainable Winegrowing is California’s original sustainable viticulture program. This program truly began from the ground up, with grape growers deciding it was important for the future of the Lodi region. Our certification process is rigorous, based in science, voluntary, and third-party accredited and audited. LODI RULES certified growers make up an innovative community with a history and commitment to farming quality winegrapes through the implementation of viticulture practices that balance environmental, social, and economic goals. LODI RULES is designed to communicate our commitment to sustainable agriculture to wineries and the general public.


LODI RULES has two key components. First, LODI RULES promotes winegrape grower adoption of over 120 sustainability practices, which are called “Standards”. The Standards were collaboratively developed by a team of Lodi winegrape growers, viticulture professionals, and scientists, and were first accredited by Protected Harvest in 2005. The LODI RULES Standards are the backbone of the program, and are organized into six Chapters: 1) Business Management, 2) Human Resources Management, 3) Ecosystem Management, 4) Soil Management, 5) Water Management, and 6) Pest Management. Each Standard meets three criteria: first, it is measurable; second, it addresses at least one of the three aspects of sustainability (environmental health, social equity, and economic viability); and third, it is economically feasible to implement. The LODI RULES Standards are the most thoroughly and rigorously vetted set of sustainability practices in California’s viticulture industry. All Standards have been peer reviewed by world renowned scientists, members of the academic community, and environmental organizations.

The second key component of LODI RULES is the pesticide risk model, PEAS, which is unique to LODI RULES. Pesticide Environmental Assessment System (PEAS) is a risk model used to quantify the environmental and human impact of all pesticides applied in a vineyard. The PEAS model generates an Environmental Impact Unit (EIU) for each pesticide, which is based on the pesticide’s impact on 1) acute risk to farm workers, 2) dietary risks from acute and chronic exposure to people who consume the product, 3) acute risks to small aquatic invertebrates, 4) acute risk to birds, and 5) acute risk to bees and pests’ natural enemies. Pesticide use by LODI RULES certified growers must fall below 50 PEAS impact units for the season.
