Why work with me?

I understand climate issues

From my 10 years working in the climate & sustainability space, I have a solid foundation of knowledge that I bring to all my work.

Because of this foundation, I can ask thoughtful questions, get up to speed quickly, and share my own relevant experiences. By understanding enough of the details, but not being fully in the weeds, I can help you translate technical complexity into compelling stories that resonate with your audiences.

Particular areas of expertise include corporate sustainability and supply chains, the clean energy transition, green buildings and climate policy.

I think strategically

My background as a communications and marketing manager means I take a strategic and joined-up approach to content writing.

I don’t just write nice content in isolation, I am always thinking about how it fits into your wider strategy and your audience’s buyer journey. This means I can advise you on what type of content you need and suggest other ways to meet your goals.

I’m reliable

I pride myself on being dependable, reliable and easy to work with.

Having worked in busy comms teams, I know how important it is to have partners you can rely on and trust to turn in high-quality work on time, every time. I’m also fully insured.

I’m an experienced writer

I’ve been writing online for well over a decade.

I’ve been fully focused on writing professionally since I started my freelance business in 2024. Before that, as a comms and marketing manager, writing content, copy and messaging was a big part of my job (and one of my favourite parts!). I used to write my own blog, The Climate Lemon, where some of my most popular posts reached over 10,000+ views, and I also write on Medium, where my articles have been published by several publications.

In 2023, I completed a course on digital writing called Ship 30 For 30, where I published 30 short essays in 30 days, sharpened by writing skills and learned best practices for digital-first writing. Grabbing attention with compelling headlines and hooks, structured pieces so they are easy to read and skim, and building trust with credibility and personality are all key.

My passion shines through

I have dedicated my career to advancing climate action and sustainability.

Like you, I’m driven by my passion for climate action and my conviction that we can create a better future if we work together to implement and scale the amazing solutions we already have.

I work exclusively with clients working on climate and sustainability who are aligned with my values. I am a signatory of the Clean Creatives Pledge.
