VERIFICATION/ ASSURANCE OPINION
On the basis of the methodology described and the verification work performed, we are satisfied that the
information and data contained within TRTC’s CSR Report of 2015 verified is accurate, reliable and provides a
fair and balanced representation of TRTC sustainability activities in 01/01/2015 to 12/31/2015.

The assurance team is of the opinion that the report can be used by the Reporting Organization’s Stakeholders.
We believe that the organization has chosen an appropriate level of assurance for this stage in their reporting.
The report is the second to be assured by an independent assurance team and TRTC has taken a bold step by
offering the report to evaluation against both GRI G4 guidelines and the AA1000 Assurance standard. This
shows a deserved confidence in their reporting process. In our opinion, the contents of the report meet the
requirements of GRI G4 Core Option and AA1000 Assurance Standard (2008) Type 1, Moderate level
assurance.

AA1000 ACCOUNTABILITY PRINCIPLES CONCLUSIONS, FINDINGS AND RECOMMENDATIONS
Inclusivity
TRTC is committed to being accountable to its stakeholders and to integrating inclusivity into its strategic and
management approach. A variety of engagement efforts such as survey and communication to employees,
customers, investors, local communities, suppliers and other stakeholders are implemented to underpin the
organization's understanding of stakeholder concerns. For future reporting, TRTC may proactively consider
having more direct involvement of stakeholders during future engagement.
Materiality
TRTC has established effective processes for determining issues that are material to the business. Formal
review has identified stakeholders and those issues that are material to each group and the report addresses
these at an appropriate level to reflect their importance and priority to these stakeholders. It is recommended
that the process and criteria applied to assess materiality to be formalized and documented to ensure better
consistent result in future reporting.
Responsiveness
The report includes coverage given to stakeholder engagement and channels for stakeholder feedback. Future
reporting would benefit from more reporting on the results of stakeholder feedback from this report.

GLOBAL REPORTING INITIATIVE REPORTING GUIDELINES CONCLUSIONS, FINDINGS AND
RECOMMENDATIONS
The report, TRTC’s CSR Report of 2015, is adequately in line with the GRI G4 Core Option. The material
aspects and their boundaries within and outside of the organization are properly defined in accordance with
GRI’s Reporting Principles for Defining Report Content. Disclosure of identified material aspects and
boundaries, and stakeholder engagement, G4-17 to G4-27, are correctly located in content index and report. It
may consider to have more descriptions of DMAs on TRTC’s internal mechanisms for monitoring the
performances, such as information collection, monitoring system, and methods for evaluating the effectiveness,
as well as to analyze the performance against goal and target for each identified material aspects.
