From Greenwashing to Genuine Impact: Best Practices for Residual Emission Management

Offsetting residual emissions is one of the most intricate and debated aspects of corporate climate action today.

The process involves navigating a labyrinth of project types, verification standards, pricing structures, and varying levels of quality. Many companies, driven by the bottom line, prioritise the cost per offset, creating a competitive rush that often sacrifices the integrity and efficacy of their offsets. This has spurred widespread accusations of greenwashing, where well-intentioned efforts can sometimes do more harm than good and invite significant public criticism.

Yet, as deadlines for net-zero targets loom ever closer, organisations must increasingly develop strategies to address their residual emissions, and carbon offsetting remains a necessary tool to do so.

Despite the challenges, there are examples of organisations that have navigated the complexity, demonstrating innovative and responsible approaches to carbon offsetting. This blog aims to showcase these best practices, demonstrating how organisations of all sizes and types can navigate the complexities of offsetting to make a genuine impact.

The importance of following best practice approaches:

In the world of carbon offsetting, following best practices is not just advisable, it is essential to avoid the pitfalls of greenwashing and reputational damage. Mis-steps and investment in lower quality offsets is a genuine risk that could result in negative media coverage and unrecoverable costs. Having a clear, robust, defensible strategy and auditable approach based on best-practice is therefore critical.

Best Practice Corporate Strategies:

Despite these offsetting obstacles, here are some best practice approaches your company could include in its offsetting strategy:

Air Capture

1. Drifters: Offsetting 100% of Residual Emissions with Direct Air Capture

2 Drifters Rum, based in Devon, stands out as the world’s first carbon-negative rum distillery. They achieve this by using 100% renewable energy, electric vehicles for deliveries, and purchasing Direct Air Capture (DAC) offsets from Climeworks. Their approach ensures that they remove more CO₂ from the atmosphere than they emit, establishing them as leaders in genuine and effective sustainability practices.

2. Stripe: Carbon Capture Market Starter

Stripe has taken a leading role in fostering the carbon capture market through substantial investments in early-stage carbon removal technologies, no matter the cost per offset. Their Stripe Climate initiative funds projects like Climeworks and CarbonCure, focusing on permanent CO₂ removal. By supporting these innovative solutions, Stripe not only offsets their own emissions but also helps scale critical technologies to bring down prices for everyone.

Nature-Based

1. Apple: Diversified & Scalable Nature-Based Approach

Apple’s Restore Fund focuses on scalable, nature-based solutions for carbon offsetting. Recognising the limitations of current air capture technologies, Apple invests in reforestation, soil carbon sequestration, and biochar, which provide immediate and additional environmental benefits.

Creating their own fund, rather than purchasing existing offsets, allows Apple to have greater control and transparency over the projects they support. This innovative approach ensures that their investments align with their sustainability values and standards. It also allows Apple to rigorously verify and monitor projects through a comprehensive due diligence process, including initial screening, site visits, financial and ESG evaluations, certification, and ongoing monitoring. This level of oversight ensures that the offsets are credible, impactful, and contribute significantly to their environmental goals.

Local Offset Approaches

1. Swansea Bay Local Authorities: Local Approach to Residual Emissions

City Science partnered with Swansea Bay’s local authorities to create a tailored carbon offsetting strategy. This effort, part of the Economic Acceleration and Regeneration Through Innovation (EARTh) Project, focused on Carmarthenshire, Swansea, Neath Port Talbot, and Pembrokeshire. The study assessed local offset opportunities and identified viable projects such as tree planting, renewable energy installations, and soil carbon sequestration where local control and vetting could also be ensured. By evaluating the feasibility, costs, and benefits of these local initiatives, the project ensures that the authorities have a robust plan to effectively offset their residual emissions and achieve their carbon neutrality goals by 2030.

2. Heathrow Strategic Planning Group: Investing in the Local Area

City Science worked with the Heathrow Strategic Planning Group (HSPG) to develop a roadmap for local carbon offset projects. The study assessed local opportunities such as retrofits, EV charging infrastructure, and tree planting. By evaluating the feasibility and potential impact of these projects, City Science helped identify strategies for Heathrow to invest in the local area, supporting both carbon reduction and community benefits. This initiative aims to create a local carbon offset market that aligns with Heathrow’s sustainability goals and the broader regional decarbonisation efforts.
