SEEDLING VS PLAN A

Plan A Alternative

If you’re looking for an alternative to Plan A, this guide can help.

Seedling is a robust carbon accounting tool built to be straightforward to run without a specialist team.

We’ll explain where Seedling is a great fit, where Plan A works better, and how to choose between them.

Seedling: Plan A, without the complexity

Plan A is a comprehensive sustainability platform built for organisations that want deep environmental insights, broad ESG coverage, and structured reporting aligned with major frameworks.

Seedling is similar, but designed to be more approachable. It enables teams - even without specialist sustainability expertise - to measure emissions accurately, build credible Net Zero plans, and make progress quickly, all with human support when needed.

Seedling may be the better fit if:

- Your organisation has up to ~2,000 employees
- You want a practical carbon solution that doesn’t require a dedicated team
- Your main goal is understanding and reducing your carbon footprint

See the detailed comparison below to understand how the platforms differ.

Plan A

Scope 1, 2 and 3 accuracy

Both platforms follow recognised carbon accounting standards and produce comprehensive Scope 1, 2, and 3 inventories. The typical starting point is financial data - analysing spend across suppliers and categories to identify major emission sources. From there, organisations refine results using activity-based data such as energy consumption, fuel use, or travel metrics to increase precision.

Platform ease-of-use

Seedling prioritises simplicity and accessibility. It’s designed for busy teams where carbon accounting is one responsibility among many, not a full-time role. Plan A offers a more feature-rich environment with extensive functionality and reporting depth. While powerful, this can require more time to learn and manage, particularly for organisations without dedicated sustainability staff.

Time to results

With Seedling, most clients can generate a robust footprint in a short timeframe. Built-in integrations with accounting platforms (including Xero, Sage, and QuickBooks), employee and supplier surveys, and automated data processing reduce manual effort. Plan A’s broader scope and setup requirements typically mean a longer implementation period before actionable insights are available.

1:1 data guidance

Both Seedling and Plan A provide access to sustainability experts who support clients throughout the data collection and calculation process. This guidance helps ensure inputs are accurate and that organisations understand their results.

Reporting granularity

Plan A supports highly detailed reporting structures, which can be valuable for complex organisations needing analysis across entities, business units, or regions.

Seedling supports companies with multiple subsidiaries as well, but maintains a streamlined process by aggregating data in ways that reduce administrative overhead while preserving decision-useful insights.

Integrations and real-time monitoring

Plan A connects with a wide range of enterprise systems and data sources, enabling ongoing monitoring and automated reporting - particularly useful for large organisations with complex data ecosystems.

Seedling focuses on integrations most relevant to small and mid-sized businesses, especially accounting tools and operational data sources that enable fast, reliable footprint calculations without heavy IT involvement.

Decarbonisation support

Both platforms extend beyond measurement to help organisations reduce emissions. Each includes modelling tools, recommended reduction actions, and expert support to guide implementation and track progress toward Net Zero goals.

Broad sustainability reporting

Plan A covers a wide spectrum of sustainability topics, including ESG disclosures and alignment with major regulatory frameworks. This makes it suitable for organisations with extensive reporting obligations beyond carbon.

Seedling concentrates specifically on carbon management - delivering high-quality Scope 1, 2, and 3 data and practical reduction planning without the added complexity of full ESG reporting suites.

Bespoke consulting

Seedling provides hands-on support to help clients succeed within the platform but does not typically undertake large custom consulting projects.

Plan A offers more tailored advisory services, including custom analyses, reports, and workshops. This approach reflects the needs of larger organisations that often require highly customised solutions.

What our clients say

Hear from our satisfied Seedling clients

"As a recently certified B Corp, finding a way to measure and reduce our carbon emissions as a business was a massive priority but we weren't really sure where to start. Seedling have been fantastic from the start at guiding us through the process, taking the time to explain and helping us improve our own knowledge, and their software has made everything a breeze! With an incredibly quick turn-around time, we have now received our insights and are looking forward to implementing the actions and targets that the team help us set in order to reduce our emissions and sharing that with our community through the integrated engagement functionality. I highly recommend Seedling and their great team, it was a pleasure to work with them and we look forward to doing so again."

“Before working with Seedling, we were managing our Carbon Reduction Plan manually in-house. The process was time-consuming, and we knew there were gaps. Seedling transformed this, making it 10 times faster and far more robust. They helped us achieve full coverage of our emissions and provided expert one-to-one guidance on decarbonisation, leaving us confident in our plan for the future.”

"We spoke to a few emission tracking partners before we spoke with Seedling, and Seedling's offer seemed too good to be true but it wasn't! Super straight forward platform, able to get face to face advice when we needed it, not expensive. Would definitely recommend."
