Copywriter carbon emissions and sustainability

We are looking for someone to source, research and write our regular client newsletter. Subjects covered are business environmental issues, primarily carbon emissions and the built environment. Articles need to be readable and accessible, yet knowledgeable and informative. Focus is on providing large companies with intelligence and information about environmental and social change. We will provide references and point you in the right direction regarding sources and subjects. Much of the content will be re-formating and editing articles and information that has appeared elsewhere online. The newsletter is produced every two months. We anticipate each issue will be between 8 and 12 pages, including at least one contributed article from another writer. Budget is per issue.
We will only consider quotes from freelancers who answer the two questions that form part of this posting.
