In China & Throughout the Developing World, Cleaner Technologies are Critical to Sustainability 20  China is the leading GHG emitter in the world, with pollution levels increasing.  Traditional technologies have failed to balance China’s economic trajectory with environmental sustainability.  Developments in fuel efficiency technology will only partially offset projected pollution.  China’s need for energy security underscores the demand for alternative fuels and clean technology.

21  Vehicle exhaust is the major cause of air pollution in China today.  A long-term sustainability strategy means better, cleaner technology.  Perceived cost and infrastructure barriers are under attack.  Upfront capital expenditure and payback periods are reconciled over the long term.  Technologies that enable alternative fuels address pollution abatement and fuel efficiency. A Critical First Step: Greening China’s Transportation Sector Refuse and vocational trucks, shuttle buses, transit buses, motor coaches, and delivery vans powered by reliable, high-performance natural gas engines are working on roads in China and carrying people every day. With the global medium- and heavy-duty vehicle market projected to grow nearly 8% between 2009 and 2014, a rapidly-urbanizing China is a significant commercial opportunity.

22 Balance Risks & Opportunities with the Right Partnerships  Continuous advances in technologies are prompting commitments by industry leaders.  For China and developing markets, solutions must be technically feasible and commercially available.  It is critical to anticipate and defeat barriers to full scale adoption of these technologies.  Strategic partnering accelerates adoption and deployment.  Weichai Westport Inc. (“WWI”), a joint venture between Westport (35% interest), Weichai Holding Group Co. Ltd.,("Weichai Holding") (40% interest) and Hong Kong Peterson (CNG) Equipment Ltd. ("Hong Kong Peterson") (25% interest) to focus on the Chinese market. WWI develops, manufactures and sells advanced, alternative fuel engines and parts that are widely used in city bus, coach and heavy-duty truck applications in China or exported to other regions globally. WWI's facility in China currently has an annual production capacity of 40,000 engines.  Westport’s Clinton Global Initiative Commitment in Rural India

Asian companies in perspective Peer performance of Asian companies with those of other regions* Percentile scores Percentage of companies in a market within a percentile range * Data from Sustainalytics platform; June 2013

Connecting with Asian companies Demonstration of an appreciation of relevant rules and regulations Tying in conversations with national (and the Party’s) goals and priorities Best practice conversations often welcomed, but there’s resistance to ‘copy-pasting’ Western models Issues such as ‘human rights, as it is holistically interpreted, may stall conversations A lack of response may not mean that your message has had no effect ‘ESG’ is a novel term; regional differences ‘Soft’ and relationship approach; sustainability leaders frustrated by lack of investor action Questionnaire fatigue Appreciation of operational contexts – flexibility in your ESG approach
