Voluntary Markets

ClimeCo’s roots are in the voluntary carbon market, developing and commercializing projects to generate high-quality carbon offsets.

Beginning with the first of six N2O abatement projects in 2010 and continuing with the acquisition of several composting projects, ClimeCo today reduces millions of tonnes of CO2e emissions annually. We actively invest in a variety of voluntary projects and maintain a diverse portfolio of offsets to meet our customers’ volume, project, and geographical diversification needs. A dedicated team and numerous global partners make ClimeCo a trusted source for voluntary carbon offsets and renewable energy commodities.

I have never before worked for an organization quite like ClimeCo. With the help of our customers, we make an incredibly positive impact on the environment. The integrity, experience, and wisdom of our executive team has influenced me personally and guided the company’s growth in the voluntary carbon market.

Project Development

At the heart of ClimeCo’s operations is an expert project development team, focused first and foremost on GHG emission reduction projects.

ClimeCo is the largest producer of voluntary carbon credits in the Climate Action Reserve (CAR), the leading offset registry in the United States. As a recognized carbon project leader, ClimeCo has received CAR’s prestigious Project Developer of the Year award multiple times.

ClimeCo uniquely combines engineering, regulatory, and project management expertise with financial and market savviness to develop carbon offset projects that produce real emission reductions while delivering positive results for our project partners. We remain involved throughout the life of the project by managing annual verification audits, reporting requirements, carbon offset issuances, sales, and the retirement of credits.

Focus Areas

Nitrous Oxide (N2O) Abatement

ClimeCo manages 100% of the N2O voluntary abatement projects in the United States. N2O abatement technology provides the highest quality and quantity of guaranteed carbon credits available in the offset market. The carbon market enables organizations to implement voluntarily N2O abatement projects that would not be implemented without the sale of the resulting carbon offsets.

As the market leader and expert in N2O applications, ClimeCo helps clients understand the technology and can design the abatement system either within the ammonia oxidation reactor (secondary abatement) or beyond the absorption column (tertiary abatement)—whichever best serves the facility’s needs.

An N2O abatement project can typically reduce from 100,000 to over 1,000,000 metric tonnes of carbon dioxide equivalent (CO2e) per year.


ClimeCo partners with large-scale composting facilities, organic waste recycling companies, and municipalities to monitor, quantify, and register GHG emission reductions generated by the diversion of organic waste from landfills. Diverting this waste reduces a landfill’s methane emissions, which result from the decomposition of organic products.

ClimeCo has been intimately involved with the development of carbon credit quantification methodologies for several carbon offset programs (many with CAR). Our current projects involve some of the largest food waste composting facilities on the West Coast.

El Dorado Nitrogen, LP, Baytown, Texas

ClimeCo developed an N2O secondary abatement system for a nitric acid process facility using the CAR Nitric Acid Production Protocol V1. This voluntary project not only generates tradeable carbon offsets, which have significant monetary value, but also improves local air quality and contributes to the reduction of GHGs. More than 6.9 million carbon offset credits have been generated since the project’s implementation.

Policy & Advisory

ClimeCo provides advisory services to entities that wish to voluntarily reduce greenhouse gases (GHGs) to meet their ESG objectives. We tailor our services to meet the specific requirements of each client and application.

Focus Areas

Green Developments

With the rise of carbon-neutral communities, many land developers are seeking innovative ways to minimize or eliminate the carbon footprints of their development projects. Two rapidly emerging approaches that developers can use to reduce their overall environmental footprints include nature-based solutions and climate forward projects.

Value-Chain Sustainability

Often, as organizations reduce their carbon emissions, they seek to influence their value chain to follow suit. With help from ClimeCo, organizations can demonstrate their environmental commitment to suppliers and partners to further contribute to the overall success of their ESG programs. For example, entities with an agriculturally focused supply chain can benefit from ClimeCo’s expertise in:

  • Agricultural methane capture systems
  • N2O abatement projects from fertilizer production
  • Grassland management
  • Environmental Mitigation

As an important part of permitting, litigation, corporate disaster response activities and voluntary corporate sustainability initiatives, environmental mitigation have become a socially and economically viable solution for many organizations.

ClimeCo has extensive experience assisting corporate clients and attorneys in navigating the wide array of mitigation options available. Some clients require complete confidentiality and discretion whereas others may wish to promote their mitigation activities. If public relations strategy is important to your company, we can assist with branding and messaging around mitigation efforts and in selecting projects, activities, and credits that best meet your business and communications needs.
