About Carbon Responsible

The rapid increase in greenhouse gas production is driving detrimental environmental changes across the world. Urgent change is needed, particularly from businesses producing far reaching and significant environmental impacts. We believe that by enabling companies to accurately measure and as a consequence, reduce their environmental impact we can help them to deliver meaningful results in the Race to Net Zero. We enable companies to effectively measure and reduce carbon emissions by simplifying their reporting processes, advising on the setting of meaningful reduction targets and monitoring progress against these targets. This new role provides an opportunity to the successful candidate to practically help businesses to become more sustainable and to mitigate climate change impacts through the measurement and minimisation of corporate carbon emissions.

Carbon Responsible was founded in 2012 to provide data driven solutions to carbon management, supported by expert advisory services. Our core focus is on the measurement, reporting, management, and reduction of corporate carbon emissions. We are a small and rapidly developing company based in London, offering a hybrid work environment.

Our key products are corporate reporting, supply chain and product analysis and the development of reduction programmes. We do not sell offsets but do advise our clients on their use and optimal product selection.

We work with a broad spectrum of clients within the UK and beyond. The nature of our work is sustained involvement with our clients to facilitate annual reporting and delivery of their reduction targets. Reduction support involves activities ranging from the enablement of renewable energy projects through to behavioural change and specialist products to deliver efficiency in transportation.

Our data products constantly adapt to meet the demands of our clients and the rapidly evolving landscape of carbon emissions measurement, accounting, reporting, and target setting.
