The document outlines the commitment of all 12 Guinness Premiership clubs to their communities through centrally managed programmes.
Initiatives include the EDF Energy National Schools Rugby Programme as well as other schemes operated by individual clubs.
Last season clubs visited just under 2,000 schools to conduct over 7,000 programmes, totalling 100,000 man hours of work.
Caborn said: "I welcome professional rugby's continual commitment and investment into community sport.
"The clubs' and players' hard work can help drive up sport participation, deliver on social inclusion and inspire the next generation of rugby players through their coaching sessions in schools."
Premier Rugby and the Premiership clubs invest over 7% of their combined turnover into community programmes.
For the second year running, Business in the Community (BITC) has awarded Premier Rugby its '% Club' standard acknowledging the substantial community investment.
Eight of the 12 Premiership clubs participate in Business in the Community's Clubs that Count programme in an effort to tackle local and national education, health and social issues.
Premier Rugby chief executive Mark McCafferty said: "For 10 years Premier Rugby and the Premiership clubs have been investing in community initiatives.
"This report highlights our growing expertise and continued commitment. Our goal has always been for clubs to be at the centre of their community.
"We are now a partner of choice for many private and public sector organisations dealing with health, fitness and social exclusion issues.
"We're keen to expand our work in these areas and to continue to make a difference."
