Geologic Carbon Sequestration
View the SCS Engineers educational library for greenhouse gas reduction and sequestration on our website – link below.


Capturing carbon dioxide and injecting it into a Class VI well for permanent geologic carbon sequestration, or CO2 storage, is a practice that industry leaders use to decarbonize manufacturing processes. Manufacturers use CO2 storage to reduce their greenhouse gas emissions and carbon footprint. There has been an uptick in proposed projects, both commercial hub-scale and single emitter-affiliated scale, particularly within the last year. The catalyst for the uptick in proposed projects is primarily the associated financial incentives, including federal tax credits and grant monies.

In this educational webinar, Professional Geologist Kacey Garber describes what manufacturers interested in geologic CO2 storage can expect the project landscape to look like in 2024. The video includes a discussion of the following:

  1. Recent and upcoming changes to Class VI Underground Injection Control (UIC) primacy or regulatory authority;
  2. Pending project status and anticipated changes in status;
  3. Recent and upcoming CarbonSAFE grant opportunities; and
  4. Evolving project opportunities in both conventional and unconventional settings.


Understanding the current project landscape and how and when future project opportunities might evolve is important for manufacturers considering the geologic storage of their CO2 stream, whether through a larger commercial hub or a smaller on-site project.

Waste Management & Research (WM&R) is offering a selection of papers published in WM&R covering a range of relevant state of the art developments in emission reductions. They supplement  recent developments with important publications that elaborate on related matters and contribute to making the case for a sound waste management that expressly and substantially supports reduction and control of GHG emissions. We hope that academic researchers and practitioners alike will benefit from this offer. 


COP28 Waste & Climate Virtual Issue is offered for a limited period of time free access to papers as fundamental points and to support decision makers on the importance of sound waste management and circular economy practices for controlling humanly-induced climate forcing.


The first paper in the line-up,  The impact of landfill management approaches on methane emissions is co-authored by Heijo Scharff, Hun-Yang Soon, Sam Rwabwehare  Taremwa, Dennis Zegers, Bob Dick, Thiago Villas Bôas Zanon, and Jonathan Shamrock.

ABSTRACT: This article reports on how management approaches influence methane emissions from landfills. The project team created various landfill operational scenarios for different regions of the planet with respect to waste composition, organic waste reduction and landfill gas recovery timing. These scenarios were modelled by applying a basic gas generation model according to the United Nations Intergovernmental Panel on Climate Change (IPCC) recommendations. In general, the IPCC’s recommended modelling parameters and default values were used. Based on the modelling undertaken, two options stand out as being the most effective methane mitigation measures in a wide range of conditions throughout the world: (a) early gas recovery and (b) reduction of the amount of biodegradable organic waste accepted in a landfill. It is noted that reduction of organic input to any given landfill can take many years to realize. Moreover, suitable alternative processing or disposal options for the organic waste can be unaffordable for a significant percentage of the planet’s population. Although effective, organic waste reduction cannot therefore be the only landfill methane mitigation measure. Early landfill gas recovery can be very effective by applying basic technologies that can be deployed relatively quickly, and at modest cost. Policymakers and regulators from around the globe can significantly reduce adverse environmental impacts from landfill gas emissions by stimulating both the early capture and flaring and/or energy recovery of landfill gas and programs to reduce the inflow of organic waste into landfills.

He is also one of our National Experts on Elevated Temperature Landfills. He has over three decades of experience on civil and environmental engineering projects related to solid waste management, and has performed landfill and landfill gas engineering projects (design, permitting, construction, and operations) in more than 15 states and several foreign countries. He is a licensed Professional Engineer in Virginia and North Carolina, a Board Certified Environmental Engineer (BCEE), and a member of the American Academy of Environmental Engineers and Scientists.

Bob has also directed and completed numerous project assignments related to solid waste planning and facility projects which have involved residential and commercial collection and recycling programs, as well as convenience centers, composting facilities, and material recovery facility design, permitting, construction, and operations consulting. He has authored several publications and made numerous presentations on air quality, solid waste management, landfill engineering and LFG management/control, design/operations, GHG emissions, composting, and regulatory compliance.

NJ Organics Summit: Addressing a Changing Climate


Organics processors, composters, haulers, regulators, academics, organics waste management professionals, sustainable community organizations, and nonprofits will join the conversation about New Jersey’s organics management practices. The Summit will feature experienced industry professionals, academics and regulators on topics of:

  • State and city food waste initiatives and climate change programs
  • The role and how to work with compostable packaging
  • Compost facility management (economics, PFAS, new techniques)
  • Funding and operating climate friendly organics business

SCS Project Director Greg McCarron is speaking at the Funding and Operating Climate Friendly Organics Businesses Panel 4 (4:00 – 5:00 pm). Be sure to visit the exhibitors and learn about some great organics recycling businesses in New Jersey!

California leads the way in the United States with a GHG MRP and C&T program that continues to grow and link with other jurisdictions. The California Air Resources Board (CARB) Market Readiness Proposal initially started with basic facility reporting and has grown and adopted to include multiple non-facility specific sectors of the economy, as dictated by the growing initiatives and programs that CARB joins or creates. However, as the program applicability may change, the basics tenants of MRP stay the same with reporting and verification at the center of the program.

By having CARB’s C&T Program as a separate program, entities have to navigate if they have a compliance obligation and how they will meet that obligation in addition to complying with reporting requirements. Entities can reduce their emissions by switching to biomass-derived fuels or meeting their compliance obligation by using CARB-provided allowances or purchasing allowances and/or compliance offset credits.

As CARB’s programs grow, it will likely trigger similar growth in the western North American GHG programs and regional agreements. As discussed, Québec’s C&T system, which is linked with CARB’s program, has been growing and is being used to meet the Canadian federal GHG rules that are being put in place. Ontario’s program was annulled but shows that the discussion on how best to reduce GHG emission is a topic that continues to thrive, and we may see new programs developing even though some may hit some setbacks. The PCC shows that even if a Market Readiness Proposal and C&T Program is not the particular method chosen by a region to reduce emissions, many regions still see reducing GHG emissions as the future to create jobs, develop the economy, develop new infrastructure and maintain growth while protecting the environment.
