Lash begins by recounting past environmental victories. He recalls using space-based environmental tracking, which, among other things, lead to Ikea making sure their wood comes from environmentally-friendly sources and helped decrease illegal logging in Cameroon. He also found tracking materials throughout the flow of economy lead to ridding arsenic from playgrounds. Furthermore, he mentioned his organization created a greenhouse gas reporting protocol that is used in carbon-credit trading.

The main portion of his talk and question-and-answer session is on the use of hydrogen as an energy source. Lash says hydrogen can or cannot be a clean source of energy. An example he uses is a car using hydrogen for fuel is a clean form of energy, but if the hydrogen is made from coal or natural gas, it is not a clean source of energy. He says nuclear-power-created hydrogen is a clean energy, but is dependent on the nuclear industry, which has not expanded in twenty years. He also recalls how corporations (Alcoa, GM, DuPont, Kinkos, etc.) created a co-operative in order to buy green power cheaply. Lash says this would work for others if given the proper governmental-policy changes. He believes wealthy nations should subsidize poor nations' clean energy initiatives since the environmental benefits are felt by both wealthy and poor nations.
