The U.S. Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) are working to finalize rules for light-duty vehicles that could significantly reduce U.S. greenhouse gas emissions.

These rules, which could be released this week, will establish new fuel economy and greenhouse gas standards for passenger cars and light trucks for model years 2017 through 2025. Light-duty vehicles represent a significant portion of U.S. greenhouse gases, accounting for approximately 17 percent of U.S. emissions. If the forthcoming rules resemble the proposed standards published by EPA and NHTSA last November, they will be an important step forward in protecting the environment and shielding consumers from higher gas prices.

Highlights from the Proposed Rules

The proposed rules would establish an emissions standard of 144 grams of carbon dioxide (CO2) per mile for passenger cars and 203 grams of CO2 per mile for trucks. If vehicles meet the standards entirely through fuel economy improvements, cars will achieve 61 miles per gallon (mpg), while trucks will achieve 43 mpg [^1]. If cars and trucks attain these standards, vehicles sold in 2025 will consume roughly half the fuel as vehicles sold in 2008 (27 mpg), emitting about half the greenhouse gases.

One week ago, with assistance from EMBARQ India, the city of Rajkot, in partnership with Nirmal Foundation, launched the G-Auto service, debuting a new fleet of auto-rickshaws, featuring a unified brand and dial-a-rixa (call-in) service, on July 13. The initial fleet includes 50 auto-rickshaws. The service will scale-up in the coming months and is expected to reach a fleet size of around 500 auto-rickshaws at the end of the first year of operations.

Rajkot, a city of around 1.3 million people in Gujarat State, India, currently has a patchwork collection of auto-rickshaw fleets and companies, with more than 12,000 auto-rickshaws currently operating, many without formal fare structures or employment benefits for drivers. G-Auto service will continue to expand its fleet in the coming months, with support from EMBARQ India and the Rajkot Municipal Corporation (RMC). This partnership, fostered by EMBARQ India, has coalesced over the past eight months to allow for safe and reliable auto-rickshaw service for the people of Rajkot.

WRI's experts will continue to provide commentary and analysis of the results of the Rio+20 conference through our series, "Rio+20 in the Rear View." Check Insights this week and next for more post-Rio+20 coverage.

As we look to make sense of the Rio+20 conference that concluded last week, we can confidently say that transportation drove its way to the top of the sustainable development agenda. It’s a far departure from the last global development conference 10 years ago in Johannesburg, when transportation was conspicuously absent from the agenda and the resulting Millennium Development Goals. After the Rio+20 conference last week, transportation is now poised to become a significant part of the forthcoming Sustainable Development Goals, which are beginning to take shape as one of the conference’s major outcomes.

With transportation intricately tied to so many of the global mega-trends today—climate change, traffic fatalities, city growth and congestion, poverty, and air pollution—it was exciting to see sustainable transport finally included in development discussions. Here are a few of Rio+20’s major transportation outcomes:

It’s the final week of Rio+20, and WRI’s experts are on the ground for all the action. Each day, I’ll bring you highlights of what’s on the horizon. Check out the details below on the exciting things happening tomorrow. And be sure to visit the full list of WRI's Rio+20 events.

The formal text for Rio+20's official outcome document was agreed to today. Meanwhile, WRI hosted its event on governance (watch the video recording here), and I had the opportunity to spend some time with New York City Mayor Michael Bloomberg, who visited Rio de Janeiro's operation center. Plus, the Mayor of Rio highlighted the EMABARQ Center for Sustainable Transportation's work on the city's first Bus Rapid Transit (BRT) corridor.

The official, three-day Rio+20 conference begins tomorrow, June 20th. Here's what's on tap:

More than 50,000 international experts and leaders from government, NGOs, business, and other sectors are flocking to the United Nations' Rio+20 Conference in Rio de Janeiro, Brazil. Taking place 20 years after the first Earth Summit, Rio+20 aims to address two major, globally important themes: building a green economy and establishing a framework for sustainable development that will decrease poverty, boost social equity, and protect the environment.

Rio+20's informal sessions kicked off last week and will continue right up until the official conference on June 20th-22nd. WRI's experts in business, climate, energy, forests, governance, transportation, and more are on the ground for all the action. (Check out a full list of official WRI events at Rio+20).

Before WRI's staff headed to Rio, I asked our experts the following question: What is significant about the Rio+20 conference, and what do you hope will come out of it?

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.

The Rio+20 informal sessions kicked off this week, 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 world leaders gather to address global sustainability at Rio+20, the summit’s host city, Rio de Janeiro, just undertook its own green initiative—it launched its first Bus Rapid Transit (BRT) corridor.

The lives of millions of cariocas, Rio de Janeiro residents, have already started to change with the opening of the Transoeste, the city’s first BRT corridor. The public transit system, developed with assistance from EMBARQ – WRI’s Center for Sustainable Transportation, expects to help hundreds of thousands of Rio residents, providing them with safer transport, shorter commutes, and less pollution.

Three global organizations recently launched a new public database of bus rapid transit (BRT) systems around the world.

Here are some need-to-know numbers of BRT trends:

13 – Cities with BRT systems in the United States

24 – Cities with BRT systems in Asia

36 – Countries with BRT systems worldwide

95 – Different indicators used in the database

129 – New corridors implemented globally since 2000

134 – Cities with BRT systems

560 – Kilometers (348 miles) of BRT in Brazil—more than any other country

3,358 – Kilometers (2,087 miles) of BRT worldwide

110,000 – Passengers on New York City’s BX Select Bus Service, the highest volume of passengers of all U.S. systems

600,000 – passenger trips daily on U.S. BRT systems

22 million – passenger trips daily worldwide
