ABOUT GREEN PLANET MAKERS
Building the link between retrofit installers and carbon markets
Installers deliver the improvements. GPM organises project evidence, supports installer participation and coordinates the carbon process through its programme relationships, including its managing-agent relationship with PNZ Carbon. Independent assurance and credit issuance take place through the applicable carbon-standard process, while GPM supports the commercial route connecting eligible retrofit activity with carbon-market value.
By rewarding measurable improvements to UK homes, we can support installer growth, reduce household emissions and contribute to warmer, more energy-efficient properties.
