This week’s Business 20, or “B20,” summit in Los Cabos, Mexico signals the launch of the Green Growth Action Alliance (G2A2), a partnership between the public and private sectors designed to dramatically scale-up private investment in “green” sectors like renewable energy, clean transportation, and sustainable agriculture.

The G2A2 includes representatives ranging from financial institutions like HSBC, to corporations like Walmart, to key public sector actors like the World Bank Group. WRI joins the effort alongside other environmentally focused organizations as an “analytical supporter,” providing research input and guidance to the G2A2’s upcoming activities.

We’re moving into the final week of Rio+20, and WRI’s experts are on the ground for all the action. Each day, we’ll bring you highlights of upcoming WRI events. Check out the details below on what we’ve got going on tomorrow. And be sure to visit the full list of all WRI events at Rio+20.

As for me, I’ll be at the climate events all afternoon today. Tomorrow morning, we’ll be bringing some journalists to visit Rio’s new Bus Rapid Transit (BRT) corridor, a system launched with guidance from WRI’s EMBARQ Center for Sustainable Transportation.

How can policymakers deliver low-carbon development, particularly clean energy, at affordable costs? What strategies have countries used to attain the economic benefits of building a clean energy industry while keeping the burden to consumers low —and who is succeeding, and why? These are just a few of the questions that policymakers grapple with when tackling the challenges associated with transitioning to a green economy, one of the key themes of the Rio+20 conference. They’re also questions that WRI seeks to answer through our upcoming, cross-country analysis of clean energy industry development.

Ten years ago, world leaders convened in Johannesburg to establish the eight Millennium Development Goals (MDGs), global strategies designed to end poverty, hunger, and disease by 2015. While the pledges were ambitious, they neglected to recognize a critical component of sustainable development: transportation. Development banks, governments, and other decision-makers spent the next decade focusing their attention on MDG priorities. Meanwhile, cities around the world faced worsening traffic congestion, increased air pollution, and dangerous roads.

We’re now face-to-face with the next major global development summit, the U.N.’s Rio+20 Conference. One of the biggest tasks at hand will be shaping new “Sustainable Development Goals,” plans that will pick up where the MDGs left off. This time, we can’t leave transportation out of the agenda.
