As policymakers and the public increasingly focus on greenhouse gas emissions reduction and sustainability, large waste management companies, including WM, Republic Services, and Waste Connections, are setting clear, quantifiable goals in their latest sustainability reports. Throughout these reports, the companies highlight their use of advanced, automated gas capture systems to reduce fugitive emissions across their landfills and meet stated goals.
According to WM’s 2023 Sustainability Report, their Connected Landfill™ technology integrates automated systems and telematics — to provide real-time data — to optimize landfill operations. By using automated wellheads, remote surface emissions monitoring, and advanced data analytics, WM maximizes gas collection efficiency and minimize emissions.
The company states that through their Connected Landfill™ technology, they are surpassing regulatory requirements for emissions. Rather than relying on manually walking the landfills, teams are “advancing measurement methods [for] more specific data that will enable us to target initiatives to capture landfill gas and reduce emissions.”
To meet the company’s goal to reduce absolute Scope 1 and 2 greenhouse gas emissions 42% by 2031, WM is focused on:
As called out in their report, WM uses strategies to reduce their landfill emissions, including:
With the goal to reduce absolute Scope 1 and 2 greenhouse gas emissions 35% by 2030, Republic Services spent $319M in Sustainability CapEx in 2022. These capital expenditures included “recycling and organics assets, landfill gas collection systems, leachate collection and treatment systems, and sustainable vehicles and infrastructure, based on the EU Taxonomy.”
As the company works toward their emissions reduction goal, it is clear from Figure 1 (below) that the vast majority of greenhouse gas emissions continue to stem from landfills.

In their 2022 Sustainability Report Climate Transition Road Map, Republic cites the need to scale specific strategies at landfills from 2023 through 2025 to get closer to meeting emissions reduction goals, including:
And from 2026 through 2029, to focus on “accelerating action” at landfills by:
According to Republic, minimizing and managing emissions from landfills to meet their sustainability goals means using technologies for “direct measurement” — to generate actionable data used to uncover the causes of emissions.
Waste Connections’ 2023 Sustainability Report highlights the company’s currently installed gas collection systems — installed “often in advance of regulatory requirements.” Collection systems are used at 55 of their solid waste landfills, with 27 of the sites equipped with facilities for beneficial reuse of the captured gas: electric generation or production of Renewable Natural Gas (RNG).
While Waste Connections is in the process of formal approval for their Scope 1 and 2 emissions reduction goal, the company mitigates fugitive emissions from their landfills by:
The publicly stated efforts of WM, Republic Services, and Waste Connections to leverage and expand automated landfill gas capture — while also using real-time, actionable data — reflect a strong commitment to sustainability and climate action.
By using automation and real-time monitoring — including LoCI’s patented data and control system to support landfill teams and reduce emissions — these companies are setting new standards for environmental responsibility and efficiency in landfill operations. The companies’ latest reports reinforce the critical role that technology and innovation play in achieving sustainability goals across their portfolios and minimizing potent greenhouse gas emissions.
