During his first term Johnson has spearheaded increased ITU-T activity in areas including: cybersecurity; climate change; and accessibility to ICTs for persons with disabilities.

His tenure has also seen a push for increased involvement of developing countries and academia in ITU's standards activities and a programme to address developing country concerns over lack of interoperability and conformity to ITU standards.

Among these achievements are his proposal for the new Global Standards Collaboration (Sydney, 2001), chairing the Reform Group on standardization prior to Plenipotentiary Conference 2002 and initiation of many reforms in ITU-T to speed up the work and increase the role of the private sector.

In addition he further enhanced the CEPT preparatory process for ITU conferences which he promoted in other regions.

This CEPT process, which includes European Common Proposals and co-ordination procedures was initiated by Jean-Louis Blanc (F) David Court (G) and Klaus Olms (D) at the Cardiff (1985) and subsequent meetings of CEPT's Radiocommunications Group, in preparation for ITU Conferences held in 1985, 1987 and 1988.
