The Carbon Removal Debate: Nature vs. Tech With UPS and Kearney

Written by Climate Impact Partners Published 27 May 2026 4 MIN READ

As expectations around net zero rise, companies are under growing pressure to decide where to invest: nature-based or tech-based carbon removals. The choice matters. By 2050, 6–10 billion tonnes of CO₂ will need to be removed from the atmosphere every year.

In our webinar, The Carbon Removal Debate: Nature vs. Tech, Climate Impact Partners brought together sustainability leaders from UPS and Kearney to explore how companies are navigating this decision in practice. The discussion moved beyond theory to focus on portfolio design, quality, risk, and the internal business case for investment.

The Carbon Removal Debate: Nature vs Tech

Watch the webinar to hear how UPS and Kearney are approaching the biggest questions in carbon removals: how they balance nature and tech, define quality, build the internal business case, and why they are acting now despite uncertainty.

Key Webinar Insights 

UPS and Kearney offered a practical view of how leading organizations are approaching carbon removals today. Four themes stood out:

  • Portfolio strategy beats binary thinking: UPS and Kearney are building blended portfolios that balance near-term nature-based solutions with durable tech-based removals, adapting their mix as their decarbonization journey evolves.
  • Credibility is the non-negotiable foundation: Both companies prioritize permanence, additionality, and third-party verification above cost considerations.
  • The business case extends beyond simple ROI: Carbon removals support broader strategic value, including client relationships, competitive positioning in RFPs, employee engagement, and long-term brand credibility. While difficult to quantify in traditional financial terms, this value shows up in customer trust and market differentiation, particularly as climate maturity increases across sectors.
  • Act early, but stay flexible: Waiting carries its own risks. Rising demand, potential supply constraints, and evolving standards mean early engagement builds access and optionality. The key is to start now with high-quality projects while retaining the ability to adapt portfolios as the market matures and internal strategies evolve.

What’s The Difference Between Nature-based Solutions and Tech-based Solutions?

  • Nature-based solutions (NBS) protect, restore, or improve the management of natural and modified ecosystems. They help address climate change while also supporting biodiversity, water resilience, and community benefits. Projects in forests, grasslands, wetlands, and oceans strengthen nature’s ability to absorb and store carbon, helping reduce greenhouse gases in the atmosphere. Learn more in our guide to nature-based solutions.
  • Tech-based solutions (TBS) help companies address hard-to-abate emissions with innovative, high-durability approaches. This includes carbon dioxide removal (CDR) solutions such as biochar, direct air capture (DAC), and enhanced rock weathering (ERW), which remove carbon from the atmosphere and store it for the long term. As one of the newest additions to the engineered solutions market, enhanced rock weathering typically comes at a higher price point, but it is poised to become a critical lever for atmospheric carbon removal and storage, both of which are widely cited as essential to reaching net zero. Together, these solutions can strengthen net zero strategies by helping companies tackle emissions that are difficult to reduce today while supporting long-term climate credibility. Learn more about CDR solutions.

A Deeper Look Into The Debate

Much of the market debate focuses on whether nature-based or tech-based removals are “better” or “more efficient.” But one message came through clearly in this discussion: that framing misses the point.

Instead of prescribing a fixed balance between nature-based and technological removals, we believe both are essential and have structured our portfolio to reflect that.
Pei Yun Teng, Senior Director of Impact & Sustainability, Kearney

Rather than treating nature-based and tech-based removals as competing choices, both organizations described building blended portfolios that can evolve over time. As Ryan King, Chief Growth Officer at Climate Impact Partners, noted, the challenge is less about picking a side and more about finding the right balance of risk, credibility, and budget while meeting internal needs and external expectations.

UPS: How It Is Building Its Carbon Removals Portfolio

Jessica Garcia, Sustainability Manager at UPS, said that carbon removals support UPS’s Carbon Neutral shipping offering for customers and are expected to play a later-stage role in its decarbonization strategy by addressing emissions that cannot yet be reduced, as we progress toward its 2050 carbon neutrality goal.

Cost matters and UPS uses a balanced mix of project types to manage price while maintaining confidence and customer trust.

Our customers can be price sensitive, so we leverage a range of options at different price points, allowing us to maintain a balanced approach with an averaged blended cost.

Quality and Delivery Risk Are Non-Negotiable

There was also clear alignment between experts on what makes a removals strategy defensible. Credibility, permanence, third-party verification, and delivery risk management were all treated as essential rather than optional.

Pei Yun and Jessica reinforced this point, stressing the importance of building a strategy that can stand up as standards and expectations continue to evolve.

  • Act early, adapt over time: While uncertainty remains, both organizations were clear that waiting carries its own risks. Rising demand, possible supply constraints, and evolving guidance, particularly around high-durability removals, mean that early engagement can help organizations secure access and maintain flexibility.
  • Kearney: How it is making the business case for carbon removals: “We think about our carbon removals portfolio approach in the broader context of our overall decarbonization strategy,” said Pei Yun. Pei Yun explained that the business case is not measured through a single ROI figure. Instead, carbon credits are evaluated in the context of broader strategic value, including credibility, client relationships, and competitiveness, especially in RFPs. Finance and legal teams are closely involved, reflecting a pragmatic approach that treats carbon removals as part of a wider decarbonization and commercial strategy rather than a standalone cost. Internally, Kearney frames carbon removals not simply as a cost, but as part of its commercial positioning.
We want to be recognized as a sustainability leader. For our credibility with clients, employees and partners, it’s important to demonstrate that we’re committed to investing in decarbonization solutions for the long run.

Navigating Uncertainty Without Losing Momentum

The discussion also touched on external pressures, from economic uncertainty to geopolitical instability and shifting market signals. While these factors may affect short-term dynamics, neither UPS nor Kearney suggested they had changed their long-term climate commitments.

If anything, rising scrutiny and future demand were seen as reasons to move early while preserving flexibility. Securing access to high-quality removals now can help organizations manage future risk even as their portfolios continue to evolve.

In Summary

The session reinforced a clear takeaway: there is no single right answer in the nature vs. tech debate. The strongest carbon removal strategies are grounded in high-quality projects, business realities, and the flexibility to evolve as the market matures.
